Introduction:

While I was performing SMPE updates under CSM, I got the error message:
"All SC package integrator threads are dead"

I cannot perform any operations under CSM now, I don't understand what may cause the issue.


 

Question:

Why do I have the message: "All SC package integrator threads are dead" under CSM?

Environment:
CSM 6.0 - Supported z/OS releases -
Answer:

A workaround is to recycle MSMTC but to resolve this problem, you have to check the values of your

MAXTHREADS and MAXTHREADTASKS parameters.

If you have the SYSVIEW product, you can select: 

MENU USS

15 USYSCONF USS system configuration options

and check what are the values for MAXTHREADS and MAXTHREADTASKS.

 

If you don't have the SYSVIEW product, to display current settings, you can run the following command:

DISPLAY OMVS,OPTIONS

You have to check what are the values for these parameters: MAXTHREADS and MAXTHREADTASKS

If these values are too low, for example 500, these values must be multiplied by 3 to support CSM, so you should have:

MAXTHREADS         1500
MAXTHREADTASKS 1500

 

You can use the SETOMVS operator command to change these values dynamically without performing the IPL of the operating system. To change them dynamically, issue the following operator commands:

SETOMVS MAXTHREADS=1500
SETOMVS MAXTHREADTASKS=1500
