software can retain up to 1,000 rolled over log files for each log that is being generated. For example, if you are generating two log files, MYDM_en_US_UTF-8.log and MYDM_fr_UTF-8.log file, you can maintain up to 1,000 backup log files for the MYDM_en_US_UTF-8.log and 1,000 backup log files for the MYDM_fr_UTF-8.log.
The number of log files retained is determined by the value of SM_BACKUP_FILE_LIMIT. When a Manager starts up, it renames a file that matches its log filename, adding a .bak to the name. If there is an existing .bak file, the .bak will be replaced with .NNN.
For example, if the SM_BACKUP_FILE_LIMIT environment variable is set to 3, the process is as follows:
-
A log file is created and it is named MYDM_en_US_UTF-8.log.
-
The MYDM_en_US_UTF-8.log file created in step 1 is rolled over:
-
The MYDM_en_US_UTF-8.log file created in step 1 is renamed to MYDM_en_US_UTF-8.log.bak.
-
A new MYDM_en_US_UTF-8.log file is created.
-
-
-
The MYDM_en_US_UTF-8.log file created in step 2 is rolled over:
-
The MYDM_en_US_UTF-8.log file created in step 3 is rolled over:
-
The MYDM_en_US_UTF-8.log file created in step 4 is rolled over:
-
Since the limit of MYDM_en_US_UTF-8.log.NNN files that are retained is set to 3, when the MYDM_en_US_UTF-8.log file created in step 5 is rolled over:
