New Database Parameter to Open Db2 for LUW Backup Files in Read-Only Mode for Deleting It

Refer to case TS005462380 for more details. Due to the rise in hackers targeting backup data files, our company has implemented Retention Lock on all backup files, including Db2 database backup files and archive log files, by changing the file permission from read/write to read-only. When the Db2 backup files or archive log files are ready to be deleted by Db2, Db2 can not delete these files, because Db2 opens the files for read/write. A database parameter to regulate this behavior would be a great enhancement to help accommodate the Retention Lock that our storage system has implemented for security reasons.

Currently, we have to delete these files using a script that executes a Linux “rm -f” command. This can be problematic and error prone, putting all backups at risk of being deleted if not done right.

As more companies implement Retention Lock on their backup files, the Read/Write restriction will become more of an issue.
