CV startup slow

Issue/Introduction

An IDMS CV is taking much longer than normal to startup.

Environment

Release: All supported releases.

Cause

This can be caused by startup AUTOTASKs, particularly if they have the PREEMPT option set.
Startup AUTOTASKs are submitted between the following two messages:

11.56.42 JOB04436 +IDMS DC013006 V7 T0 ATTACHING STARTUP AUTOTASKS
11.56.42 JOB04436 +IDMS DC013005 V7 T0 CENTRAL VERSION INITIALIZATION COMPLETE

If a startup AUTOTASK has the PREEMPT option, then that task must complete before user tasks are allowed to run.
This can have the effect of delaying startup.

Resolution

Investigate any startup AUTOTASKs defined for the CV and ideally determine if any have the PREEMPT option.
If it is acceptable for the application, change it to NOPREEMPT.
