david2008:

I see you already have your problem solved. I wanted to mention, though, that instead of using a file, you could use the database itself. At the start of the run, check whether a lock entry exists in the table. If not, add an entry to the table. Do it in a transaction so you can avoid any race conditions. Then, when the run ends, delete the entry.

I only mention it because you're already pounding on the database.

When your only tool is a hammer, all problems look like your thumb.

    [Corion]: oiskuu: Depends on what you want to do with that information
    [tye]: I'm not depending on that feature. But I could in this environment. I'm using getlogin(). shrug
    [Corion]: For benign logging (which user started this DB instance), it's OK
    [tye]: We use auditd for security monitoring. So we can rely on auditing being enabled. I'm not sure who would want to not be able to audit. Maybe some VM inside another system with audit?
    [SuicideJunkie]: spies would want a system to not be able to audit.
