Upgrade to PT 8.54 "Converting Database Data Types" step for Oracle Unicode DB
The Task 1-6 (Converting Database Data Types) for the upgrade of PeopleSoft PeopleTools from 8.53 to 8.54: We use Unicode Oracle DB. The sub task "Reviewing Oracle Settings" instructions indicate that the character length semantics (NLS_LENGTH_SEMANTICS) had to be set to "CHAR" in init.ora for Unicode databases. The note in the documentation specifies that this change to be made at this point of the upgrade.
The following sub task, "Generating Oracle Conversion Scripts" had instructions to set db_block_size, SGA_TARGET, SHARED_POOL_SIZE etc to specific values.
Question: Is there a point during or after the upgrade that the NLS_LENGTH_SEMANTICS need to reset to its original setting (ours was set originally to BYTE)? Same question regarding the values for the items referred in the Generating Oracle Conversion Scripts step. There was no step/documentation indicating a reset and wondering if I have to reset these or should leave them as they are.
