IBM i Data Queue damage

Post by MarkDuignan » Mon Oct 12, 2015 6:47 pm

For LongRange RPG users only …………

We have encountered two instances in the last year of IBM i data queues in library LRNG_TEMP becoming ‘damaged’.

IBM i object damage is most likely to happen when your IBM i terminates abnormally (eg: a power outage with no UPS).

The risk of this type of object damage causing an operational problem can be eliminated by clearing library LRNG_TEMP when restarting after an abnormal IBM i shutdown. Use the CLRLIB command to do this.

Alternatively, many sites shutdown their QINTER and AXES subsystems regularly (eg: every night). So if you always clear LRNG_TEMP before restarting subsystem QINTER and AXES you would eliminate this risk and minimize disk space usage.

LongRange RPG incorporates the aXes product.
The following aXes Administrators guide section talks about when to stop and restart aXes.
This is the point where including a CLRLIB LRNG_TEMP would be beneficial
