Custom OIM Login Code Fails On OIM 11g Clustered Deployement (Doc ID 1415376.1)

Last updated on JULY 21, 2020

Applies to:

Identity Manager - Version 11.1.1.3.0 to 11.1.1.5.0 [Release 11g]
Information in this document applies to any platform.

Symptoms

Implemented a custom java class (login part of the code shown below) which implements the OIM APIs to perform various actions in OIM on a two node cluster (node1 on host1 and node2 on host2):

Hashtable env = new Hashtable();
env.put(OIMClient.JAVA_NAMING_PROVIDER_URL, PROVIDER_URL);
env.put(OIMClient.JAVA_NAMING_FACTORY_INITIAL, OIMClient.WLS_CONTEXT_FACTORY);
OIMClient oimClient = new OIMClient(env);
oimClient.login(USERNAME, PASSWORD.toCharArray());


The code uses the string: "t3://<hostname1>:<port>/oim,t3://<hostname2>:<port>/oim" to connect to the 2-node OIM cluster.
This fails with the following exception :

When connecting to node 1 only (meaning using the "t3://<hostname1>:<port>/oim" URL), login calls are successful.
