Question: 

JOB05 in Configuration allocates the SYSCTL file. 

When is this dataset populated - when you bring the system up for the first time? 

What gets put in the dataset? 

Answer

CV writes to the SYSCTL file from info in SYSTEM definition at every Startup and every Shutdown. 

DSECT #OPIDS describes the SYSCTL file (and IDMSOPTI). 

Mainly the SYSCTL file contains the SVC number and CV number for the CV and additionally a Nodename/DBname if one is defined for SYSCTL in the system statement. 


It also indicates if the CV is active or has been shutdown.

 

Here is an example of the contents of SYSCTL when the CV is active:

000001   NDOPI   Ðk Ð 4     

       00DCDDC400A90A0FD000 

       0054679000C2AC74E000

Here is an example of the contents of SYSCTL when the CV has been shutdown:

000001     OPIX  Ðk Ð 4

       0044DDCE00A90A0FD000
