Error: "peoplesoftpsappserveragent encountered an exception and ldbal value in the psappsrv.ubb file is not turned on."
PeopleSoft configuration not enabled.
You will need to change the settings on your PeopleSoft server. The LDBAL value in the psappsrv.ubb and the psprcs.ubb files should be turned on (change N to Y) to get data on Queues and Requests in the PS_AppServer and PS_SchedServer agent tables.
After these changes are made the application server domains should then be recycled by shutting down, then using the psadmin command to regenerate the PSTUXCFG file and starting (booting) the domain. The changes in the .ubx and.cfg files above will take effect and the respective data will be collected.
