Last updated on FEBRUARY 03, 2019

Applies to:

Oracle General Ledger - Version 12.1.3 and later
Information in this document applies to any platform.


The following error is encountered when performing an account inquiry.

ORA-03106: fatal two-task communication protocol error
FRM-40505: ORACLE error: unable to perform query.

The issue occurs for all users and seems to occur only when the intercompany segment is populated with a value. It doesn't happen for all of them, but does each time a specific intercompany segment value is used.

Users perform inquiry every month and say that it worked fine before this month.


Recently upgraded our database from 11.2.04 to and also applied January CPU and PSU patches.
