FAQ - Upgrade procedures

A list of questions and answers related to upgrade procedures:

Q:How do I upgrade a component that was originally installed without SSL configuration?
A: To configure SSL attributes, perform the following steps:
  1. Set the security_level parameter to force_enabled in the workstation definition and the secureaddr parameter to the secure port, as described in Configuring SSL attributes.
  2. Set the nm SSL full port parameter to the value of the secure port in the localopts file. For more information, see Localopts details
Q: What happens if I do not remember the password for the default certificates?
A: Before starting the upgrade, test the passwords for the certificates using the following keytool commands:
  • keytool -list -keystore TWSServerTrustFile.jks 
-storepass my_password
  • keytool -list -keystore TWSServerKeyFile.jks 
-storepass my_password
Q: Can I install a backup master domain manager at version 10.1 Fix Pack 5 in a back-level environment?
A: If you have a back-level environment, for example version 9.4, you can install a backup master domain manager at version 10.1 Fix Pack 5, but it is recommended you check your security configuration.
Most 9.4 environments are not configured with SSL, which is enabled by default starting from version 10.1. To ensure communication between all components, perform the following steps:
  1. Install the fix for APAR IJ47731, if your current environment is earlier than 9.5 FP4. To obtain the fix for your product version, contact Software Support.
  2. Install the backup master domain manager at version 10.1 Fix Pack 5.
  3. Stop on the backup master domain manager at version 10.1 Fix Pack 5, as described in Application server - starting and stopping.
  4. Browse to the following paths:
    on Windows operating systems
    TWS\broker\config
    on UNIX operating systems
    TWS/broker/config
  5. Set the Broker.Workstation.PortSSL property to false in the BrokerWorkstation.properties file.
  6. Start on the backup master domain manager at version 10.1 Fix Pack 5, as described in Application server - starting and stopping.
  7. 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.
