Issue/Introduction

After recycling of DB2 the SYSVIEW for DB2 Data Collector started task does not start. 

The Data Collector finished with RC=00 and DBG39039I message.

DBG39039I TERMINATION COMPLETE FOR DATA COLLECTOR FOR DB2 SUBSYSTEM SSID

Environment

Release : 20.0

Resolution

There was the following error message in the Data Collector output.  

DBG46005E DBT2 03:54:42 MEMBER RECORD NOT RETURNED FROM IXC FUNCTION
  
The DBG46005E error message is a problem with Sysplex and Data Sharing.    

 DATA-SHARING=YES             /* DATA SHARING IQL AND PROCESSING
*  DC-GROUP=                    /* INSTALLATION DC GROUP NAME    

Normally the DC-GROUP parameter is wrong and the Data Collector was not able to communicate with the other Data Collector members of the Data Sharing. All the members in the Data Sharing should have the same DC-GROUP parameter.  
  
However in this particular case there was a SSM (OPS/MVS) error and the Data Collector was not able to communicate with the other members in the Data Sharing. 
  
After the SSM (OPS/MVS) error was fixed the Data Collector started up correctly.
