Answer

If the DB2 backup history file db2rhist. asc is damaged during database backup, and the error code SQL2048 is incorrect, perform the following steps:

1. Find the file in the NODE000x/SQL000x directory and its backup file db2rhist. bak to move the db2rhist. asc file to another directory.

2. Run the BACKUP command again. This command still reports the same error, but the DB2 system will automatically use db2rhist. bak to regenerate the db2rhist. asc file.

3. Run the BACKUP command again to run it correctly.

If the same error persists after performing the preceding steps, perform the following operations: 1. find the file in the NODE000x/SQL000x directory and its backup file db2rhist. bak to move these two files to other directories.

2. Run the BACKUP command again. This command still reports the same error, but the DB2 system will automatically regenerate the two files.
