ORA - series Errors Occur During Oracle Database 11g Export Operation, Preventing Normal Completion

edited Apr 29, 2025 5:23PM in Database Utilities (MOSC) 2 commentsAnswered

Dear Oracle Support Team,We encountered issues while performing a database export operation using Oracle Database 11g Enterprise Edition Release 11.2.0.4.0.The export command we executed was `expdp system/sysdba DIRECTORY=backup_expdp CONTENT=METADATA_ONLY DUMPFILE=xxx schemas=hytpdxxx,hytpdyyy`. During the operation, multiple errors occurred: - First, when attempting to switch users to execute the command, we got the error `su: incorrect password` (although we later successfully executed the relevant command as the root user). - After executing the export command, a series of ORA errors appeared, including `ORA-31626: job does not exist`, `ORA-31638: cannot attach to job SYS_EXPORT_SCHEMA_xx for user SYSTEM`, ORA - 06512 - related error

Howdy, Stranger!
