admin repository configuration for LAC 5 in cluster

[Ido Neamani]

If I would like to 2 instances of LAC 5.0 (deployed on apache tomcat servers)  to run as a cluster with admin repository.

In such scenario, Does the admin repository folder be configured in a shared mapped folder to each of the tomcat nodes so each instance of the LAC will point to this shared admin repository folder  ?

Or should each lac instance in the cluster should write to its own dedicated admin repository ?

This topic is quite vague for me and I will be glad if someone can provide additional info regarding it and how does each of the lac instances in cluster should be synced with each other. 

 

Thanks,

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.
