Ensuring communication in your environment

Security is enabled by default starting from version 10.1, but is usually no configured in most back-level environments. If security is not configured in your current environment, perform the following steps to ensure all IBM® Workload Scheduler components can communicate correctly:

Install the fix for APAR IJ47731, if your current environment is earlier than 9.5 FP4. The fix is available on IBM Fix Central for version 9.4 FP7. For other product versions, contact Software Support. For more information, see IJ47731: CHECKSYNC JOB FAILED IN IWS 10.1 FP02 - AWSJCL075E ERROR
Install the backup master domain manager at version 10.2.2.
Stop WebSphere Application Server Liberty Base on the backup master domain manager at version 10.2.2, as described in Application server - starting and stopping.
Browse to the following paths:

on Windows operating systems

TWS\broker\config

on UNIX operating systems

TWS/broker/config
Set the Broker.Workstation.PortSSL property to false in the BrokerWorkstation.properties file.
Start WebSphere Application Server Liberty Base on the backup master domain manager at version 10.2.2, as described in Application server - starting and stopping.
Run the following commands on the back-level master domain manager:
1. ```
optman chg cf = ALL
```
  This command changes the enCarryForward option so that all incomplete job streams are carried forward.
2. ```
JnextPlan -for 0000 -noremove
```
  This command extends the production plan without removing successfully completed job stream instances.
3. ```
optman chg cf = <original value>
```
  This command returns the enCarryForward option to its original value.

The new backup master domain manager can now communicate with the back-level network.

If you want to switch the new backup master domain manager to master, stop the broker on the back-level master domain manager, and switch it to master domain manager.

What to do next: You can now proceed to Configuring security.
