Replacing OSGi bundles in an OSGi JVM server

Use this update method when service outages can be tolerated during the update process. No new CICS® resources are created, but you might need to update the existing BUNDLE resource definition.

To replace an existing OSGi bundle in an OSGi JVM server with a new version of the OSGi bundle, use the following steps.

1. In the Bundles view in CICS Explorer®, disable and discard the BUNDLE resource for the CICS bundle that you want to update. The OSGi services that are part of that CICS bundle are removed from the OSGi framework and are not listed in the OSGi Services view of CICS Explorer.
   Note: No services that are implemented by the OSGi bundle are available in the OSGi framework from this point until the completion of step 3, so any users of these services suffer a service outage.
2. Optional: Edit the BUNDLE resource definition if the updated CICS bundle is deployed in a different directory in zFS.
3. In the Bundles view in CICS Explorer, install the BUNDLE resource definition to pick up the changed OSGi bundle. The OSGi bundles and services in the CICS bundle are installed in the OSGi framework.
4. Check the status of the OSGi bundle in the OSGi Bundles view in CICS Explorer. The new version of the OSGi bundle is listed with a state of active.
5. In the OSGi Services view in CICS Explorer, check that the new version of all the OSGi services that are implemented by the new version of the OSGi bundle are in the active state.
