Receiving Multiple Copies of the Same Message

Try these possible solutions:

After implementing SYSPLEX, you may see duplicate messages from external systems on local consoles. To prevent this, change the MSCOPE parameter to local-system-ID or *.
For example, if D C,* shows that MSCOPE=*ALL, and this console is receiving duplicate messages, then enter the following z/OS command:
```
VARY console,MSCOPE=*
```
Users of CA Remote Console who use CA MIC to collect message from external systems to local CA Remote Console sessions, should specify SYSPLEX=NO on the RCSINIT statement to prevent duplicate messages from being displayed at the local RCS session.
