When the DB2 transaction log space is full, the following solutions can be implemented:
1. Increase transaction log space: The transaction log space can be expanded by increasing the number of log files or increasing the size of each log file. Using the ALTER DATABASE command to increase the number of log files, and using the ALTER TABLESPACE command to increase the size of each log file.
2. Compress transaction log: Use the COMMIT WORK AND DISCARD command to compress the transaction log. This command will delete the committed transaction logs from the transaction log file, freeing up space.
3. Commit unprocessed transactions: Check for any uncommitted transactions and either commit or rollback. Uncommitted transactions can occupy transaction log space and cause the transaction log to become full.
4. Regularly backup transaction logs: Regularly back up transaction logs to delete committed transaction logs from the transaction log file, freeing up space.
5. Increase the number of transaction log files: Increasing the number of transaction log files can increase the available space for transaction logs. Use the ALTER DATABASE command to increase the number of log files.
6. Monitor transaction log usage: Regularly monitor the usage of transaction logs and take measures to prevent the transaction log from becoming full. Please note, before operating the database, backup the database to prevent data loss.
