Excessive long runtime in phase ACT_TRANS during upgrade to EHP7ERP6
we are running an upgrade on an ERP system (Linux SLES12 & MaxDB 7.9), with target EHP7ERP6.
For some reason phase ACT_TRANS (activation of customer objects) takes in excess of 10 hours(!!!)
There seem to be no errors in the log files and the system is doing something (activity in SM50 and "top" shows some stuff happenning on OpSys level, too), its just happening very, very slowly.
There is never more than 20% load on system resources (RAM, disk, a.s.o.), no excessive swapping and never more than 2 or 3 disp+work processes active at once.
For me it looks like the system is activating one object at a time and that very, very slowly.
Is there any way to speed this process up?
For this is the test run for your production box and with 10+ hours for that phase alone, I am afraid we can't keep our downtime window.
As alway, thx in advance for all helpful replies.
SAP has by now (finally) looked at our system and they claim that, if the number of support package stacks to be imported is big enough, then 2+ days of solid runtime for step "execution" would actually be considered fast :-(
And the same goes for 5+ days for just building up a shadow system, should we decide to go that route.
They say there is nothing we could do to speed up either one of those processes.
