IFM IPC Exception
-------------------------
Hi, I'm trying to update process variables using IFM, but it's failing at the update stage with error message "An IpcException has occurred while invoking the method: setProcessVariable on process-execution2 (localhost:5024)". I know this is a permissions issue, but I am already an administrator of the process I am trying to update, so what other permissions are there?

Is the IFM node set to "Run as whoever started the process" ?

In addition to consider what was suggested above, can you post the rest of the stack trace? There should be several "Caused by" clauses describing the root cause.

Search for the phrase "Caused by", the stack trace you posted doesn't have it, meaning it's not useful to determine the root cause.

The relevant error is:
com.appiancorp.kougar.driver.exceptions.IpcObjectClassException: invalid object class: class java.lang.Long
this is not permissions related. It indicates Appian was expecting a Long but got something else instead. It seems the issue is with your syntax to update value assuming you're using the IFM Manager Plug-in.
To avoid errors I suggest you use this other one instead "Get and Set External Process Variables" which is easier to use for the purpose of updating a variable

Hi,
"Get and Set..." isn't really an option as I need to update multiple processes, plus the associated security and tasks. I managed to get the original query to parse, it was just a case of getting it to include speech marks around the variable. However, I now have an issue with updating a user type - with or without the quotations it fails to parse. It is of the form:
UPDATE 287 SET PV brm_User= [simondev] WHERE [pv!areaCode_text = 112]
Any idea what form this should take?

1. Creae a process variable of type user and assign the desired value
2. Run this
UPDATE 287 SET PV brm_User= [pv!myUserVariable] WHERE [pv!areaCode_text = 112]
