Resolve "CWPKI0734E Could not connect to the job manager" in WebSphere

This error appears when attempting to register as application server or deployment manager with a job manager.

 

When completing the form to regster an application server or deployment manager with the job manager, ensure the hostname is the hostname of the job manager server. The port should be the port of the job manager, which is 9943 for HTTPS or 9960 for HTTP by default. Use the HTTP port of security is not enabled, and use the HTTPS port if security is enabled.

 

Ensure the job manager is running. For example, if the job manager is running on a Linux server, the ps command can be used to determine if the job manager is running. If the ps command produces a long string of text, the job manager is running.

~]# ps -ef | grep JobMgr
root 28476 1 0 Feb09 ?  00:15:45 /opt/IBM/WebSphere/Dmgr/profiles/JobMgr01 . . .

 

Ensure the job manager, application server, and admin agent are using similar security configurations. For example, if the job manager is configured to use Federated repositories for authentication, then the admin agent and application server should also be configured to use Federated repositories for authentication.

 

On the job manager server, check the SystemOut.log. For example, the SystemOut.log may have an SSL connection exception. In this example, the cause of the problem may be that the job manager, application server, and admin agent are not using similar security configurations.

~]# cat /opt/IBM/WebSphere/Dmgr/profiles/JobMgr01/logs/jobmgr/SystemOut.log
. . .
SSLC0008E: Unable to initialize SSL connection. 
Unauthorized access was denied or security settings have expired. 
Exception is javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
