Why might a process erratically report an ORA-00068 for a consistent "alter session set sort_area_size"? There is some code setting workarea_size_policy to manual and attempting to set sort_area_size to 2147483647. The value is hardcoded so it doesn't change. But sometimes the code works, sometimes it doesn't. Code was called from a job on a two node cluster. Error when raised is consistent: ORA-00068: invalid value 214783647 for parameter sort_area_size, must be between 1835298655 and 0. Running the commands manually in a sqlplus session works consistently. Thoughts? Cheers, Dominic
