Java LSFFlowJob exception during Import/Export of deployedFlows.

[sangeeta128]

We are trying to migrate from SAS 9.4 M7 to M8 version, we have client running on Windows citrix server (Windows Server 2019 Standard) and RHEL servers (RHEL 😎 for the metadata and application server.

The problem we are having is when we do import of the 'deployedflows' on the servers, it works fine when we import  from windows server but when we run the batch tool from linux servers it throws the below error at the end. We get a similar error when we also run the export command, all objects containing flows failed.

Also we noticed that if we run these commands using root access then it runs fine but with the sas user it gives this error.

Could someone help me on this please.

The platform.picklist file is the list of jars to load that includes the com.platform.LSFJobFlow class. Check the version of PlatformComputing_PM listed in the platform.picklist and confirm that version is present in <SASHome>/SASVersionedJarRepository/eclipse/plugins/, and that directory includes jobflow.jar.

[sangeeta128]

yes the version matches.

Version from platform.pickup -

This version also exists in /opt/sas/bin/SASVersionedJarRepository/eclipse/plugins/

Hi @gwootton 

We found the problem, thank you for leading us to the right location to check. 

The permissions of the jobflow.jar was not proper that's the reason it was running with root user but not the user we were using.

Thank you very much!

The error  says ClassNotFoundException:.
Please make sure the java is accessible\le to the SAS user running this job. JAVA_HOME must be included in his path.
This can be easily checked by running env in the bash shell.

[sangeeta128]

I'm having this issue only when I try to import/export the objects with type "DeployedFlow". Other import/exports works fine with the SAS user so I guess that concludes that the Java is accessible otherwise all import/exports would have failed.
