I was installing CA SOI 4.2 in MSCS environment. My plan is to install EEM in Cluster environment, since it is now available with 4.2 version.I installed the EEM on both the nodes and i ran the HA kit, but it failed. I installed the EEM along with Manager.
I don’t think you can run HA Toolkit for EEM Cluster setup.
Here is the procedure to setup EEM in failover.
Can you please check below document where it says that EEM can be installed on Cluster.
How to Configure Node A - CA Service Operations Insight - 4.2 - CA Technologies Documentation
Below is that Article.
The CA EEM release that is shipped with CA SOI uses CA Directory as its data store. This component provides built-in support for data store replication. When CA EEM is installed in a cluster environment, data store replication ensures that customization of the Operations Console such as preferences, users, and group configuration is consistent regardless of the active node. We recommend data store replication to eliminate the need to repeat configuration and preferences on each node.
When CA EEM is installed on two cluster nodes, Node A reports to CA EEM on Node A when active. Similarly, Node B reports to CA EEM on Node B when active. CA EEM has its own data store on each cluster node. Each CA EEM is configured to extract LDAP data individually, because this data is not replicated.
Complete the following process to configure CA EEM data store replication:
Specify SOI-<VIRTUALNODE> in the Application Name field.
When you run the HA Resource Kit on each cluster node, a page opens asking to configure CA EEM data store replication if CA EEM is installed on the cluster node. Click Yes on this dialog.The Resource Kit customizes the required files for multi-write, which automatically synchronizes the application data in the CA EEM data store. This data includes Operations Console privileges, groups, and preferences, but not external users and groups extracted from external sources such as Active Directory.A confirmation page opens.
Configure CA EEM on each cluster node regardless of data store replication. If CA EEM is configured to use an external directory, configure each node, because external directory data is not synchronized.
The communication on cluster nodes is already trusted, so CA EEM data store replication does not use certificates in a cluster environment.
Got your point.
Basically, EEM is not cluster aware but in this scenario we are installing EEM on 2 SOI Cluster nodes as documented below
What is the error when running HA toolkit? Can you attach a screenshot?
So basically i tried various methods:-
1) Installed EEM on 2 nodes which are in cluster. Ran HA kit (SSAHA). Gave me an error. Snapshot attached.
2) Installed EEM on 2 nodes which are in cluster and performed the steps as mentioned by you https://docops.ca.com/ca-embedded-entitlements-manager/12-51/en/configuring/failover-configuration/how-to-set-up-a-failover-environment/configure-a-primary-server
It ran perfectly fine. No Errors
3) Installed EEM on 2 nodes which are in cluster and then installed SOI Manager (Manager, MQ Server and Universal Connector Client) on the same 2 nodes (Since as per the document EEM needs to be installed along with SOI Manager). Ran the HA kit (SSAHA), it asked me to select the cluster drive and completion pop up came. Snapshot attached.
But as per the document, it says that the HA kit page opens asking to configure CA EEM data store replication if CA EEM is installed on the cluster node. This did not happened with me.
Hello Ankur, can you please raise a case with CA Support to followup on this.
Thanks and kind regards,
Ankur had raised a support case, after following the SOI Wiki page for this configuration, now EEM is configured as explained in the document
