Environment

Release : 18.0, 18.1

Component : Endevor Software Change Manager

Cause

Using the default PoolMaxSize="0" for ENDEVOR.cfg so STC Pooling was disabled.

If STC Pooling is enabled, ENF will submit spawn task WSEWSSTC as soon as Tomcat starts.  

If STC Pooling is disabled, ENF won't submit spawn task WSEWSSTC until Endevor user issue the REST or SOAP request (For example user can issue REST API request using Endevor Eclipse Based UI or ZOWE CLI Endevor plugin). 

Resolution

To enable STC Pooling configure a non-zero PoolMaxSize per: Install and Set Up Web Services > Configuration Files > How to Enable STC Pooling
NOTE: Maximum value is 40.
