Just a few considerations about the COLD start.
What is a COLD start ?
> A COLD start will clear out the MQ (Message Queue) tables, that are used by server processes (CPs and WPs).
When should a COLD start be performed ?> Usually after updating the Automation Engine server (binaries and database).
> Sometimes,
old messages can be left in the MQ tables causing the Automic system to
not be able to start correctly, or freeze. The most common reason for
this is if the Automic system has been brought down ungracefully.
Does a COLD start impact task processing?> All tasks which were executing
any script (status: "generating", "post-processing",
etc.) will be in status "inconsistent" after the cold start.
> All "open" statistic
records (without end - timestamp) will be checked. If they are no longer
in activity window they will get a end time stamp.
How to perform a cold start ?> I listed 3 different ways of doing it in
this post.
