Fix Oracle Temp Tablespace Release Issue

When the Oracle temporary tablespace cannot be released, it may be due to uncommitted transactions or long-running queries locking the tablespace. Here are some ways to resolve this issue:

1. Ensure there are no pending transactions: First, use the following SQL statement to check for any uncommitted transactions:
2. Retrieve all the columns from the V$TRANSACTION table.
3. Make sure that any pending transactions are either properly committed or rolled back.
4. Make sure there are no long-running queries: Use the following SQL statement to check for any long-running queries:
5. Retrieve the SID, SERIAL#, USERNAME, and SQL_ID from the V$SESSION table where the STATUS is ‘ACTIVE’.
6. If there are long-running queries, consider terminating these sessions to free up table space.
7. Manually release table space: If the above methods cannot solve the problem, you can try releasing table space manually. First, use the following SQL statement to view the usage of table space:
8. Retrieve the file name, size in bytes, maximum size in bytes, and if the file is set to automatically extend from the database temporary files.
9. Next, manually release table space using the following SQL statement:
10. Resize the temporary file path in the database to zero.
11. The temp_file_path is the path of the tablespace to be released.
12. Restarting the database instance: If the above methods do not solve the problem, you can try restarting the database instance. This will forcefully release all table spaces, but it will interrupt the normal operation of the database, so please proceed with caution.

If the above methods fail to resolve the issue, it is recommended to contact the Oracle database administrator or technical support for further diagnosis and resolution.
