James,

I did this a long time ago. From memory (others will correct me if incorrect):

- do a SHOWLOGSTATUS to get the logid. The logid is likely set to AUTO (switch automatically to a new file when a certain size is reached).
- stop logging with the LOG logid;STOP
- Backup all the logfiles you have already then purge them from disc
- use the ALTLOG command to change the name of the logfile name to use e.g. HLHAM001
- start logging with LOG logid;START

The logging should be synchronized with database backups. We used to do the following at backup time:
- CHANGELOG (force switching to the next logfile in the sequence)
- LOG ;STOP
- Backup the database and associated logfiles
- LOG ;RESTART

Again, this is from memory. The command options and sequence may be a bit different but should be close I think.

Hope this helps a little.

François

Subject: [HP3000-L] Managing Image Logfiles

Now that the 918 has my attention and I am dusting off my old skill-set anyway I am doing a little housekeeping. One of the items I have encountered involves Image logging, which is something I never knew very much about to begin with.

We have a bunch of old Image log files having the form HLHAM999 where
999 appears to be a serial number.  Unfortunately we seem to have used up all the numbers (001-999) and the logging process seems stuck on using a single file (HLHAM899).  So my question is does the logging process automatically rollover and reuse old log files or do I have to purge these things myself? I am guessing the latter but I would like to know for sure.

Supplemental questions: If I must perform a manual purge then how to I handle the logging process?  Do I stop it and purge everything?  How to I set the serial number for the logger when I restart it?  In fact how do I turn the logger off and on if that proves necessary?

Sorry to publicly wallow in my ignorance here but I truly cannot remember how I set this up to begin with and I cannot afford the time to go research everything from scratch.
