IBM i Data Queue damage
Posted: Tue Oct 13, 2015 10:47 am
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.
