When you are running LAC in a cluster, both nodes must be looking at the same admin repository.
This can be accomplished by either:
1. Starting up all nodes by pointing to a URL or Git having the repository using the LAC_REPOSITORY_CONFIGURATION_URL startup option.
See: Configure Live API Creator to Run as a Cluster - CA Live API Creator - 5.0 - CA Technologies Documentation
2. Bundle the WAR file of Live API Creator with your admin repository, and install the updated WAR on all of the nodes.
See: Example: Deploy the Bundled WAR to a Cluster - CA Live API Creator - 5.0 - CA Technologies Documentation
Note that when you are running in a cluster, LAC should be serving as the runtime platform processing the API requests. You should not be making any changes to the APIs running on a cluster.
Hope this clarifies your question.
Many thanks for this info. now it is clear for me.
i will walk through the documentation and point the prod nodes to a URL
