There is no other solution but to back up the database to try the above scheme, but also encounter the above error in the logical backup. You have no choice but to use rman for backup.

According to the document 1940340.1, it may be that the application of PSU is caused by oracle buf.

Follow the steps as follows:

Create pfile='/home/oracle/pfie.ora' fromspfile;\

SQL > alter system set java_jit_enabled = FALSE;-10g is not required

SQL > alter system set "_ system_trig_enabled" = FALSE;

SQL > alter system setJOB_QUEUE_PROCESSES=0

SQL > startup restrict

SQL > @ catbundle.sql psu apply-restore parameters after running

SQL > alter system set "_ system_trig_enabled" = TRUE

SQL > alter system setJOB_QUEUE_PROCESSES=10

Restart the database.
