This ORA-04045 errors are related with the Privileges Issue for system User

The upgrade documents precisely states below in the section “Requirements and recommendations for Source database”
“Disable any custom triggers that would fire before/after DDL and enable them after the upgrade is complete.”

It is strongly recommended to abide by the pre-upgrade tasks as mentioned in the upgrade document.

TRIGGERS Should be disabled Prior to Upgrade.

1. We should disable all the triggers before staring the upgrade

To Disable :-

SQL> SELECT ‘ALTER TRIGGER ‘ || owner || ‘.’ || trigger_name || ‘ DISABLE;’ “ALTER Statement” FROM dba_triggers where TRIGGER_TYPE in (‘BEFORE EVENT’,’AFTER EVENT’,’AFTER STATEMENT’);
Example :-

alter trigger XXXXXXXXX disable;
To Enable:-

SQL> SELECT ‘ALTER TRIGGER ‘ || owner || ‘.’ || trigger_name || ‘ ENABLE;’ “ALTER Statement” FROM dba_triggers where TRIGGER_TYPE in (‘BEFORE EVENT’,’AFTER EVENT’,’AFTER STATEMENT’);
Example :-

alter trigger XXXXXXXXX ENABLE;

Or

2. Provide below Privileged

SQL> GRANT ADMINISTER DATABASE TRIGGER to SYSTEM;

Prior to upgrade to restart the Upgrade .

“_system_trig_enabled” = FALSE

Or set the following parameter to solve this error.

SQL> ALTER SYSTEM SET "_system_trig_enabled" = FALSE scope=both;
System altered.
