Notice: WP_Scripts::localize was called incorrectly. The $l10n parameter must be an array. To pass arbitrary data to scripts, use the wp_add_inline_script() function instead. Please see Debugging in WordPress for more information. (This message was added in version 5.7.0.) in /var/www/wp-includes/functions.php on line 5663
So – I spent 7 hours working through a fancy REST API script, reading optimisation notes on Powershell queries, and re-working and re-writing the code to be simple and clean to finally post up a detailed ‘warts and all’ article.
And then I actually tried to use it! And it, er, didn’t quite go to plan.
So what is the issue?
Let’s look at a fairly basic hierarchy:
I’m using the Entity hierarchy in a fairly standard format. Reasonably ragged, some levels go to state and some into country, but functionally nothing that Essbase doesn’t handle perfectly.
Let me add the level zero flags.
Top section makes perfect sense – the issue comes with the Entity_NA member. Remembering the way our query works, for summary members we iterate to find the parent member of each level zero.
And now you can see the problem (and hopefully not just because I highlighted it in bright red). We have a ragged hierarchy, so the summary levels are ragged as well. While perfectly correct, this is very likely not what we want.
Fortunately- we’re in Powershell Country
Looking at the qualified names gives us a good idea on how to solve the issue though. By adding a “ParentMember” variable to the prompt, we can then filter on the qualifiedName to get only the members that have this upper level member.
{$member.items | Where qualifiedName -like "*``[$ParentMember*" | where childCount -eq "0"} #select only level zero UNDER the parent member
$Filename = "F:\PBCS_REST\Output.csv"
$AppName = "Demo"
$Dim = "Entity"
$Lev = 1
$ParentMember = "Total_Entity"
# Convert creds to auth headers
$Enc_Auth = [System.Text.Encoding]::UTF8.GetBytes(("{0}.{1}:{2}" -f $Domain, $Username, $Password))
$Enc_PW = [System.Convert]::ToBase64String($Enc_Auth)
$PBCS_REST_URL = "{0}/aif/rest/V1/applications/{1}/dimension/{2}/" -f $URL, $Appname, $Dim
$AllMembers = Invoke-RestMethod -Uri $PBCS_REST_URL -Method GET -Headers @{"Authorization"="Basic $($Enc_PW)"} -ContentType "application/json"
$Finalmembers = foreach($member in $AllMembers) # iterate through all the members
{$member.items | Where qualifiedName -like "*``[$ParentMember*" | where childCount -eq "0"} #select only level zero UNDER the parent member
while ($Lev -gt 0) # for any level higher than 0, recursively query
{
$lookup = foreach ($member in $Finalmembers) # for every member in the previous list (or level 0 for the first pass)
{$member.parentName} #add the parent names to the lookup table
$lookup = $lookup | sort -Unique # grab only the unique parents
$Uppermbrs = foreach ($member in $allmembers) #iterate through the entire list again
{$member.items | where {$_.memberName -in $lookup}} #filter now on the members in the lookup
$lev -- #iterate through the levels
$Finalmembers = $upperMbrs #assign the upper members to the new list
}
$Finalmembers | Select-Object memberName -Unique | ConvertTo-Csv > $Filename -NoTypeInformation # select the uniques and convert to csv
Much better! Now I can actually use this function to set up my Hybrid Dynamic Calc members correctly. The full updated Get-LevMbrs function is available below!

Obviously there are a number of manual ways to do it – simple Smartview exports, exporting the dimension and parsing the file, even writing a custom database export out to flat file – but none of them are particularly elegant and\or streamlined and would be very difficult to integrate into a metadata update.
When John mentioned that he had found a way, I was obviously intrigued! Basically in his investigation of the FDMEE on-prem to Cloud integration processes he found an undocumented data management query to return all of the members from within the requested dimension:
GET URL/aif/rest/V1/applications/App/dimension/Dim/
This query is from the data management layer – specifically querying the underlying FDMEE \ Data management tables that are populated by the target application metadata queries.
Running this query manually then returns a detailed listing of every single member including a large volume of metadata.
Unfortunately? It’s not the best metadata. ‘MemberLevel’ is a misnomer – basically you have +1 for the dimension name and -1 for everything else. ‘QualifiedName’ is useful, but because it’s a parent child listing you still need to iterate in order to actually identify where you are. Still – we should be able to construct some queries to give us what we want!
Let’s start nice and simple – setting up our query:
$Username = "Username"$
Password = "password"
$URL = "https://planning-test-pivot2.pbcs.ap1.oraclecloud.com"
$Domain = "pivot2"
$AppName = "Demo" # This is the name of the Planning application
$Dim = "Entity" # This is the dimension you're querying
$Filename "F:\PBCS_REST\Example.csv"
# Convert creds to auth headers
$Enc_Auth = [System.Text.Encoding]::UTF8.GetBytes(("{0}.{1}:{2}" -f $Domain, $Username, $Password))
$Enc_PW = [System.Convert]::ToBase64String($Enc_Auth)
$PBCS_REST_URL = "{0}/aif/rest/V1/applications/{1}/dimension/{2}/" -f $URL, $Appname, $Dim
$AllMembers = Invoke-RestMethod -Uri $PBCS_REST_URL -Method GET -Headers @{"Authorization"="Basic $($Enc_PW)"} -ContentType "application/json"
$AllMembers | ConvertTo-Csv > $Filename -NoTypeInformation
This returns everything and utilises powershell’s built in csv converter to render something reasonable.
Useful but not what we want – let’s build out a query to just return level 0 members.
$Finalmembers= @() # Create an array for the members
try{
#Trigger the dim query
$AllMembers = Invoke-RestMethod -Uri $PBCS_REST_URL -Method GET -Headers @{"Authorization"="Basic $($Enc_PW)"} -ContentType "application/json"
foreach ($member in $AllMembers)
{$Finalmembers += $AllMembers.items | Where-Object {$_.childCount -eq "0"} | Select-object memberName -Unique }# filter for the level 0 members (where no children)
$Finalmembers | Select-object memberName -Unique | ConvertTo-Csv > $Filename -NoTypeInformation # select the uniques and convert to csv
}
Catch {throw $_.Exception.Message}
We can’t use a level indicator, but it’s simple enough to just check if the members have children. This now returns us a nice simple list of members.
Great! So Level 0 is nice and easy. Recently however, I’ve been doing some work with EPBCS Hybrid and found myself reminiscing about Celvin’s incredible Essbase Member Operation Utility – specifically it’s ability to bulk update higher level members to a new storage type. So I got wondering, what if we want greater than level 0?
$Lev = 2 #define the level to return
# Trigger the Dim Function
$Finalmembers= @() # Create an array for the members
#Trigger the dim query
$AllMembers = Invoke-RestMethod -Uri $PBCS_REST_URL -Method GET -Headers @{"Authorization"="Basic $($Enc_PW)"} -ContentType "application/json"
foreach ($member in $AllMembers) {
$Finalmembers += $AllMembers.items | Where-Object {$_.childCount -eq "0"} | Select-object memberName,parentName -Unique # filter for the level 0 members (where no children)
}
while ($Lev -gt 0) # for any level higher than 0, recursively query
{
$upperMbrs=@() # build an upper level array
foreach ($member in $Finalmembers) # for every member in the previous list (or level 0 for the first pass)
{
$upperMbrs += $AllMembers.items | Where-Object {$Finalmembers.parentName -eq $_.memberName} #give the details where the previous levels parent member equals the member name
}
$lev -- #iterate through the levels
$Finalmembers = $upperMbrs | Select-object memberName,parentName,alias -Unique # select only the unique members (to make the recursion quicker)
}
$Finalmembers | Select-object memberName -Unique | ConvertTo-Csv > $Filename -NoTypeInformation # select the uniques and convert to csv
So this is a little more convoluted – but basically we’re finding the Level x members – getting all their parents and then looping and recursively searching up the hierarchy.
One note to make at this junction – this is not speedy code. Recursive loops through the pipeline with a where-object as a filter is….about as bad as you can get for performance! It’s not that awful – pulling big dimensions (10k+ members) takes around 5 mins. Buuuuut….yeah, performance is important. Let’s re-write it.
$AllMembers = Invoke-RestMethod -Uri $PBCS_REST_URL -Method GET -Headers @{"Authorization"="Basic $($Enc_PW)"} -ContentType "application/json"
foreach ($member in $AllMembers) {
$FinalMembers = $member.items | where childCount -eq "0"
}
Firstly changing to a where clause from a where-object clause removes our script block meaning we can only do a simple comparison, but this massively speeds up the iteration.
while ($Lev -gt 0) # for any level higher than 0, recursively query
{
$lookup = foreach ($member in $Finalmembers) # for every member in the previous list (or level 0 for the first pass)
{$member.parentName} #add the parent names to the lookup table
$lookup = $lookup | sort -Unique # grab only the unique parents
$Uppermbrs = foreach ($member in $allmembers) #iterate through the entire list again
{$member.items | where {$_.memberName -in $lookup}} #filter now on the members in the lookup
$lev -- #iterate through the levels
$Finalmembers = $upperMbrs #assign the upper members to the new list
}
$Finalmembers | Select-Object memberName | ConvertTo-Csv > $Filename -NoTypeInformation # select the uniques and convert to csv
For the recursion – building the parent member as a lookup list with a single iteration means we can run through it much quicker.
Much much quicker.
But wait! You want to query using generations instead of levels? Alright then. We can’t use recursion up the ParentName hierarchy, instead we’ll use a (glorious) hackjob and look at the qualifiedName. By counting the number of members in the qualifiedName reference we can work out which generation it is!
$Gen = 5
$v2 = (measure-command{
$AllMembers = Invoke-RestMethod -Uri $PBCS_REST_URL -Method GET -Headers @{"Authorization"="Basic $($Enc_PW)"} -ContentType "application/json"
foreach ($member in $AllMembers)
{$Finalmembers = $AllMembers.items | Where-object {(($_.qualifiedName) -ne $null) -and (($_.qualifiedName).split(".").count -eq $Gen)}}
$Finalmembers | Select-object memberName -Unique | ConvertTo-Csv > $Filename -NoTypeInformation # select the uniques and convert to csv
}).totalseconds
Write-Host ('15k members {0} secs' -f $v2)
Same basic logic – except we’re filtering out the nulls, and then counting the number of “.”‘s to define how deep we are in the hierarchy.
A bit slower – but reasonable given the size of the dimension.
Hopefully that helps – I’ve built out the queries above as powershell functions available below – feel free to modify, use etc as needed, making sure to always test test and test again before running anything in Production.

So, this is really a continuation of the previous one. Just as a recap:
the REST API is awesome
It lets us do all of the same functions as EPMAutomate, but with significantly better error handling and logging abilities
It also has a few ‘new’ tricks up it’s sleeve
I make terrible REST puns.
So – RESTating the Obvious
Where I’d left off, we’d written a powershell script to delete the existing load file, upload a new load file, run a data load run and IF it errors download the log.
Great for one file, but what if we have a bit of data…what if we have a folder?
And this is what that log file looks like – remember we’re only getting the logs for the failed loads.
SquaREST peg in a Round Hole
So let’s talk about the FDMEE\Data Management log for a moment.
In many ways, this is literally the best log of…well, anything…that you can currently get out of PBCS. No access to the Essbase calc log, no access to the FR logs, no access to the MDXQuery logs.
So this is literally a replica of the FDMEE log, with options to set the log level and capture all the detail.
But, it’s still a bit all over the place. The actual reporting of errors is pretty good, but we’re definitely going to need some parsing to get anything useful out of it.
So looking through it, the errors we’re looking for are here:
This is the standard error code for an essbase (ASO) data load with missing metadata.
A pipe and comma delimited error handle broken down by line with the following fields:
Note: If anyone can think of a method of pulling that order out dynamically from anywhere else (specifically the UD1+ order), please let me know!
The FaiREST Parser
So if we grab the second field, we’ve got the specific missing members that failed. That’s fairly easy to parse in Powershell
# Okay - this is where we get fun...
$AllMissingMembers = New-Object System.Collections.Generic.List[System.Object] #create a list for the missing members
Get-Content $Logfilename | # open the file
Select-string "Error: 3303" | # find any Error 3303 strings (Missing members)
foreach{ #for each error row
$data = $_.line.split("|",[System.StringSplitOptions]::RemoveEmptyEntries).Trim(); # split them into members and data rows
$AllMissingMembers.add($data[1]) #build an list of missing members
}
$UniqueMembers = $AllMissingMembers | Select -unique # select the unique items
Without wanting to write a discourse on powershell, the functions are as follows:
Create a generic list object
Open the file (get-content is a little slow with bigger files, but these are pretty small)
Grab all of the rows that start with “Error:3303”
For each of those rows, split up the rows using the “|” delimiter
Grab the second item in the row (arrays start at zero!) and add it to the list
Once you’ve got all the members, create a unique list
Wham Bam – we have a unique list of members in a powershell list.
Now, to be honest we could stop here. It’s pretty easy in Powershell to just write that member list into an email – attach the data lines to give it context – and send it to the administrator.
But, 8 lines of code does still not a good blog post make. We’ve got the REST API – let’s try to get fancy.
Conceptually it’s great. Useful for new projects, new employees, new assets etc. Gives the users the ability to dynamically add metadata and can be fully scripted in with @RETURN controls and validation.
It’s the biggest downside? It doesn’t work in Smartview – and in reality, that’s such a gamebreaker that I’ve gone off it completely in PBCS, or alternatively on premise ‘created’ my own with the groovy CDF.
But – this process isn’t user facing – so let’s see what we can do with it!
Let’s create a couple of “Unmapped” nodes in our dimensions
Obviously you’d want to select only as many members as you’re likely to need per load file – and remember these get created in the essbase cube, so don’t add 300 additional hidden members in your dense dimension!
Once that’s done and refreshed into essbase – we can call the REST command to add members to those nodes.
For this we need to connect to the Planning API:
REST Resource - Add Member
POST /HyperionPlanning/rest/{api_version}/applications/{application}/dimensions/{dimname}/members
Similar to the dataload process, we’ll be creating a payload to post through the body of the REST POST query.
Similar, also to the dataload process, the documentation is slightly incorrect.
Instead of Name the member must be listed as memberName.
foreach($UniqueMember in $UniqueMembers) #Now we have a unique list of members, lets iterate and add them!
{
$CreateMbrURL = $URL + $RESTPlanning + "/dimensions/Product/members" # Create the Rest Add Member URL
# Generate the Add Member payload
$AddMemberPayload = "{
""memberName"": ""$UniqueMember"",
""parentName"": ""Unmapped Product""
}"
#Create the member
$restReponse = Invoke-RestMethod -Uri $CreateMbrURL -Method Post -Body $AddMemberPayload -Headers $Headers -ContentType "application/json"
If ($restReponse.Status -gt "0")
{write-host "Member Creation Unsuccessful - " + $restReponse.Details}
Else
{write-host $UniqueMember "- Member created Sucessfully"
}
Obviously I’m being lazy and not generating the ParentName dynamically – up to you as to how you achieve this, but assuming your dimension members are all prefixed with the same letter it should be reasonably easy. You could also create multiple dynamic child enabled members within a single hierarchy – might be useful to map unmapped Balance Sheet members into one node and unmapped P&L members to another.
Importantly, the new member seems to inherit the data storage operator from it’s parent member. Which is useful, because every possible permutation of the actual documentation that I tried didn’t work.
"dataStorage": "STOREDATA" #what the documentation says
"dataStorage": "Store Data" #what the response body is
"DataStorage": "StoreData" #removing spaces
"DataStorage(FINRPT)": "Store Data" #Similar to the planning header
This was made even more frustrating because every failed attempt doesn’t return an error message, but instead a full 500: HTML Error. So, once again, if anyone knows the correct syntax, please let me know?
RESTructuring the cube
So now we’ve dynamically added the members that are missing, we need to refresh the essbase layer. In ‘theory’ (though I didn’t test this) – if you were loading through the Planning connection, you wouldn’t even need to do this step! But because we’re loading into the ASO cube, let’s refresh the cube.
This also opens up another REST API command: executing a job.
Nice and simple – first you create a job within PBCS and then you call it. Since Cameron Lackpour has already enthused the world with multiple blog posts on the topic I won’t belabour the point.
Basically create a refresh cube job and give it a name you remember.
Once that’s done, we call it very similarly to any other planning command, setup a quick payload and run it.
#Now all the metadata has been added, trigger a database refresh
$RefreshURL = $URL + $RESTPlanning + "/jobs" # Create the Rest refresh URL
# Generate the refresh cube payload
$RefreshPayload = "{
""jobType"": ""CUBE_REFRESH"",
""jobName"": ""Refresh_with_Kill""
}"
$restReponse = Invoke-RestMethod -Uri $RefreshURL -Method Post -Body $RefreshPayload -Headers $Headers -ContentType "application/json"
$RefreshURLResponse = $RefreshURL + "/" + $restReponse.jobID
$RefreshComplete = $false
while(-not $RefreshComplete)
{
#Call the status of the job
$Checkrunning = Invoke-RestMethod -Uri $RefreshURLResponse -Method Get -Headers $Headers -ContentType "application/json"
#check if the status is still running
if ($Checkrunning.status -eq "-1")
{
#wait for 5 secs
Start-sleep -seconds 5
}
Else
{
#if the refresh is a sucesss,
if($Checkrunning.status -eq "0")
{
#Job was sucessful
write-host "Refresh Sucessful - " $Checkrunning.details
}
Else
{
#job failed
write-host "Refresh Failed - " $Checkrunning.details
}
$RefreshComplete = $true
}
}
Once again – we have to roll our own process to check when the job is complete. Calling the REST API job by itself will simply run the job, but for this step we need to wait for it to complete . Perhaps surprisingly (or perhaps not), this is different to the loaddata API calls.
From the original POST REST command we get the JobID, and then we run a GET command on that Job ID and we get the status. Why Oracle decided to change between the definition of Status and Details between the Data Management API and the Planning API is a question best left for the Oracles.
RESTuffing the Turkey
(The puns are really getting tortured. Sorry)
Final Step? Reload the data of course!
# invoke Request to Reload the data
$restReponse = Invoke-RestMethod -Uri $DataLoadURL -Method Post -Body $Payload -Headers $Headers -ContentType "application/json"
$responseURL = $restReponse.links[0].href
$ReloadComplete = $false
while(-not $ReloadComplete)
{
#Call the status of the job
$ReloadRunning = Invoke-RestMethod -Uri $responseURL -Method Get -Headers $Headers -ContentType "application/json"
#check if the status is still running
if ($ReloadRunning.Jobstatus -eq "RUNNING")
{
#wait for 5 secs
Start-sleep -seconds 5
}
Else
{
#If the load is a sucess, confirm
if($ReloadRunning.Jobstatus -eq "SUCCESS")
{
#job completed
write-host "Data Reload Sucessful - " $ReloadRunning.jobStatus "Executed by " $ReloadRunning.executedBy
}
Else
#It may have failed for another reason (not metadata) - post details
{
#job failed
write-host "Data Reload Failed - " $ReloadRunning.details
}
$ReloadComplete = $true
}
}
This is simply a repeat of the original data load commands. Only item of interest is that I’m using different variables ($ReloadComplete) as strictly speaking I’m still within the error handle of the original data load process.
So. What does this actually look like over a folder? Specifically this folder?
Well – to be honest, it looks pretty damn amazing.
Dynamically creating metadata, refreshing the cube as it goes and reloading only the impacted data files.
Going TerRESTrial
Once completed, it’s Child’s Play…I mean Childz play…I mean Child’s Play to add the new members to an email to the Admin\Business owner to move them to their correct home.
So there you have it, a fully automated, metadata creating, folder loading, fully logging, back to base emailing, data load process that doesn’t require EPMAutomate to run.
Not too bad for less than 250 lines of code!
As always, I’m deeply indebted to previous works from Jake Turrell and John Goodwin – without whom I would have undoubtedly given up.
Full code line available below. As before don’t run code against a production environment that you don’t understand, and make sure it’s doing exactly what you want before you do!

I’m not one to wax lyrical, but y’all are amazing. I’m honoured to call you my friends.
So – what’s next
So after an amazing week, returning from KScope17 I found myself full of verve and enthusiasm, motivation and endorphins Actually, Becky is always this enthusiastic…bad example.
So I figured I’d hit the ground running and bang out multiple quick posts about the REST API in PBCS. Also gives me an excuse to make bad REST puns through the entire post.
Needless to say, 4 weeks, 1 SR, 2 OTN posts, hours trolling though the amazing John Goodwin’s blog backlog and some urgent twitter DM’s to the guru and I’m finally ready to post.
RESTating the background
So, I could write a whole background of what a REST API is and it’s benefit to developers – but I’ll leave this to the very talented Jake Turrell. This is his recorded session from KScope 16, where he discusses the anatomy of a REST API request, talks through JSON and does a live demo (because doing something completely crazy and unsupported in front of a live audience is ALWAYS a great idea!).
It was one of my favourite presentations from KScope16 so I cannot strongly recommend it enough!
Without further RESTraint
So now you know what the REST API can do, let’s throw some code at the wall and see what sticks.
I’m going to walk through a very simple (and oft repeated process!) of uploading a datafile to a PBCS instance and triggering a data load rule.
Firstly though, let’s see what the same process looks like in EPMAutomate.
The code lines are fairly simple – Oracle has exposed REST functions through very simple batch parameters
Steps are:
Login
Delete File
Upload File
Trigger data load
Logout
And this is what it looks like for a successful run:
And this is what it looks like with a failed load – I’ve added a data record for an entity that doesn’t exist
UncleaREST logging ever…
So we know we ‘can’ do it through EPMAutomate, but that logging is pretty atrocious. For anyone wondering, the EPMAutomate command does return an Errorlevel, but it doesn’t return any real details and there is no way to easily identify and grab the log.
POST /interop/rest/{api_version}/applicationsnapshots/{applicationSnapshotName}/contents? q={"isLast":true,"chunkSize":444,"isFirst":true,"extDirPath":inbox\}
GET /interop/rest/{api_version}/applicationsnapshots/{applicationSnapshotName}/contents
My code language of choice for today is Powershell – I’m still a bit rusty with Groovy, and Powershell has a very useful set of REST functions built in.
So the first tasks are to set variables, pass through some parameters and define the authorisation headers. I’m going to use the very elegant get-content function to pull all my variables from an XML file (read more about that here). In addition, I’m defining the specific REST API URLs for both the LCM and Data load functions.
We also need to create an encoded header for authentication – the format of which is as follows:
Domain.Username:Password
This then needs to be encoded into UTF8 and THEN converted into a base64string and added to a JSON header.
We can then split up the folder and file names to generate all of the required parameters. This is where using a ‘real’ code language is incredibly helpful – giving you a set of string and file system parsing parameters rather than needing to roll your own.
So we finally get to our first REST command – the delete function.
For this command we need to URL encode the file path of the target to pass it through
Basically that converts the following path:
inbox/BS/BS_Actual_Jan-13.txt
into
inbox%5cBS%5cBS_Actual_Jan-13.txt
We then send the REST Delete command with the authentication header and the URL encoded filename. We also set the content type:
-contenttype "application/json"
in order to get the query return information in a JSON format.
This is where we start to see the value of using the REST API for queries. If a REST query fails, we will get a set of return information – in the case of the Delete function, we get the following return dataset in a JSON format.
Which we can easily parse into an actual error handle – Note: I got this simply by running the delete function twice
Much better than EPMAutomate and a simple ErrorLevel!
PRESTaging Data
# LCM Rest URL (for uploading files)
$inboxfolder = $inboxfolder.Replace("\","/") # The insanity as to why I have to do this....
$UploadURL = $URL + $RESTLCM + $LoadFile + "/contents?q={""isLast"":true,""chunkSize"":500,""isFirst"":true,""extDirPath"":""$inboxfolder""}"
#Upload File
$restReponse = Invoke-RestMethod -Uri $UploadURL -Method Post -Headers $Headers -Infile ($LoadPath + "\" + $LoadFile) -ContentType "application/octet-stream"
If ($restReponse.Status -gt "0")
{write-host "File Upload Unsuccessful - "$restReponse.Details}
Else
{write-host "File Upload Successful"}
Now we deal with the upload, and this is where the ‘/’ deliminators get a little funky.
My URL is basically the REST API plus a filename, but I have to now define an extDirPath to load a file into the inbox directories for data management. Unfortunately this needs to be parsed as a Unix file path, therefore the slashes must be reversed
$inboxfolder = $inboxfolder.Replace("\","/") # The insanity as to why I have to do this....
In another ‘learn from my mistakes and frustrations’ – the documentation indicates that the folder structure is “extDirPath”:”/inbox”
However this is incorrect – you don’t need a leading ‘/’ before inbox. This is the correct final syntax:
Now onto the data load – the first step is defining a REST body payload – this defines the load periods, job name, import and export modes as well as the (optional) filename.
Once again, this is where the documentation differs from the reality.
Note only a single Period is listed? Yeah. Anyways, through trial and error – mostly by looking at what the EPMAutomate commands were using – I tested startperiod and endperiod and it worked.
So here we get to the final load commands. The data load trigger is a POST command, passing through the Payload in the body, and the standard headers.
Remember that the API URLs are different between the LCM (data import\export) and the Data Management URLs. Specifically, the data management URL is
aif/rest/V1/jobs
The second command
$responseURL = $restReponse.links[0].href
is defining the rest response URL for this specific load – once again, very useful because we can poll this using a REST GET to check the status of the load.
$Jobcomplete = $false
while(-not $Jobcomplete)
{
#Call the status of the job
$Checkrunning = Invoke-RestMethod -Uri $responseURL -Method Get -Headers $Headers -ContentType "application/json"
#check if the status is still running
if ($Checkrunning.Jobstatus -eq "RUNNING")
{
#wait for 5 secs
Start-sleep -seconds 5
}
Else
{
#if the load is a failure, download the log
if($Checkrunning.Jobstatus -eq "FAILED")
{
$Logname = [System.Web.HttpUtility]::UrlEncode($restReponse.LogfileName.Replace("/","\")) <# The definition of insanity.... #>
$DownloadURL = $URL + $RESTLCM + $Logname + "/contents"
Invoke-RestMethod -Uri $DownloadURL -Method Get -Headers $Headers -ContentType "application/json" | Out-File -FilePath $($LogFolder + "\" + $Rulename + "_" + $LoadPeriod + ".txt") -Force
write-host "Job Failed - Log Downloaded -" $($LogFolder + "\" + $Rulename + "_" + $LoadPeriod + ".txt")
}
Else
{
#job completed sucessfully
write-host "Job completed Sucessfully - " $Checkrunning.jobStatus "Executed by " $Checkrunning.executedBy
}
$Jobcomplete = $true
}
}
The final component of the script – and this is where using the REST API shines. By polling the job status we can check for a failed run – and then, because one of the return codes is the logfile name (see $restReponse.LogfileName) we can then selectively download that specific log file.
Note once again we have to deal with some slight insansity – the filename of the log is a returned as a windows format (‘\’ slashes) whereas to download the file we need to convert it BACK to a unix format. We then use a fairly standard GET command and write the output to a text file.
ARESTted Development
So there you have it, a full walkthrough of uploading a datafile and triggering a load rule using the REST API.
I’ll put the full code at the bottom – mostly to help anyone deal with the insanity of needing to chop and change the folder paths. Standard caveats apply, don’t run code you don’t understand in your production instances (or any instances!) and no warranties implied or otherwise.
I’ll be noting some of the updates\issues in the documentation and sending something through to Oracle – would make a lot of this development significantly easier!
Next I’ll be extending this process a bit further – actually parsing the downloaded log into actionable errors!
Any questions\issues, leave a comment. Happy RESTing!
Cheers
