Required diagnostic data collection for RMAN backup
1. Provide the alert.log and related tracefile of the target database.
2. Provide details on the location where backup is being placed. I.e., tape, local disk, nfs mount, data domain, etc. Call the file srdc_rman_backup_answers_<date>.txt before submitting.
3. Submit rman script. Rename the script to srdc_rman_backup_script_<date>.txt before submitting.
4. Submit full rman output of execution. Rename the output file to srdc_rman_backup_output_<date>.log before submitting.
5. If possible, reproduce the error/issue with debug enabled using:
a. Before invoking rman, set the following environment variable:
Unix:
export NLS_DATE_FORMAT='DD-MON-YYYY HH24MISS'
Windows:
set NLS_DATE_FORMAT=DD-MON-YYYY HH24MISS
b. Invoke rman with:
rman trace=srdc_rman_backup_debug_<date>.trc log=srdc_rman_backup_output_<date>.log
c. execute:
connect catalog ..... /* if rman catalog is being used */
set echo on;
debug on;
<COMMANDS>
debug off;
6. If it is impossible to re-execute, connect to the target database and capture:
- Download attached script srdc_rman_backup_output.sql
- Connected as SYSDBA run the script
eg:
SQL> @srdc_rman_backup_output.sql
7. Compress (in .zip or .tar.gz format) all above files. Call the file srdc_rman_backup_details_<date>.zip/.tar/.gz before uploading to SR.
The following files are expected to be uploaded:
srdc_rman_backup_answers_<date>.txt
srdc_rman_backup_script_<date>.txt
srdc_rman_backup_output_<date>.log
srdc_rman_backup_debug_<date>.trc
ps:
REM srdc_rman_backup_output.sql - collect RMAN information with backup.
