com.tibco.objectrepo.OperationFailedException: Error retrieving stream for VFile.

Resolution

This issue happens when the temp folders are corrupted, the temp folder has been cleaned or there is not enough space.
By default, system TEMP folder is being used by Java programs like Administrator/Hawk Agent and AppManage. We can configure temp folders for Administrator/Hawk Agent and AppManage to a different folder. Thus no other process will share this temporary directory so this kind of problem can be avoided.

  --in hawkagent_domainname.tra add the following parameter:
            java.property.java.io.tmpdir=/ust/tibco/hakwagent_tmp
  --in tibcoadmin_domainname.tra add the following parameter:
            java.property.java.io.tmpdir=/ust/tibco/admin_tmp
  -- in $(tra_home)/5.x/bin/AppManage.tra, add the following line:
            java.property.java.io.tmpdir=/ust/tibco/app_tmp
  --restart both Administrator and Hawk processes.

Check these temp folders for size regularly and make sure there's enough space for the temporary files. If you are cleaning up the temporary files, make sure that Administrator/Hawk Agent and AppManage are not running on the machine while doing so.
