When the DB2 table space is full, you need to perform cleaning operations to free up space. Here are some common cleaning methods:<\/p>\n

    \n
  1. Delete tables or indexes that are no longer in use: By checking the usage of tables and indexes, removing objects that are no longer in use can free up space. You can use the following command to find unused indexes:<\/li>\n
  2. Retrieve the table name and index name from the SYSCAT.INDEXES table where the STATISTICS_TIME is not yet recorded.<\/li>\n
  3. Then use the DROP INDEX command to remove any indexes that are no longer in use.<\/li>\n
  4. Reorganize the tablespace: You can use the REORG TABLESPACE command to reorganize the tablespace and free up space. For example, you can use the following command to reorganize the tablespace:<\/li>\n
  5. Reorganize the tablespace named .<\/li>\n
  6. Clean up log files: You can free up space by using the ARCHIVE LOG command to remove archived log files from the active log directory. For example, you can use the following command to clean up log files:<\/li>\n
  7. Save the log file for the database in the specified destination .<\/li>\n
  8. is the destination path for archived logs.<\/li>\n
  9. Compress Tablespace: The COMPRESS TABLESPACE command can be used to compress the free space in a tablespace and release space without losing data. For example, you can use the following command to compress a tablespace:<\/li>\n
  10. Shrink the tablespace named .<\/li>\n
  11. Adjusting the tablespace size: If the tablespace size is set too small, you can use the ALTER TABLESPACE command to adjust its size. For example, you can use the following command to increase the tablespace size:<\/li>\n
  12. Increase the size of the tablespace with ALTER TABLESPACE command.<\/li>\n
  13. The size has been increased.<\/li>\n<\/ol>\n

    Before performing any cleanup operations, make sure to back up the database and related log files to prevent data loss. Additionally, the cleanup process may have a certain impact on the performance of the database, so it is necessary to carefully assess and plan before execution. It is best to perform cleanup operations during non-peak hours.<\/p>\n","protected":false},"excerpt":{"rendered":"
