Information in this document applies to any platform.
While upgrading to 22.214.171.124 (with DB PSU 126.96.36.199.160419 applied),the Oracle 12c-DBUA-upgrade process sets PGA_AGGREGATE_LIMIT to 2 GB.
This causes pga_aggregate_target > pga_aggregate_limit.In example below pga_aggregate_target has been set to 3700MB before upgrading to 12c. The DBUA set pga_aggregate_limit to 2 GB, so 3700 MB for PGA can’t be used. This forced an ORA-04036 in alert.log
Target Home had the April 2016 DB PSU 188.8.131.52.160419 Patch 22291127 installed
