J2EE connect failed

[Former Member]

Hi All

How to check j2ee connect is successful or not?

What does exactly j2ee connect check ..connection from <where> to <where> ?

We are frequently recieving alerts like j2ee connect failed.

How dbconnect is  different from j2ee conect.

Thanks

Hi

Thank you all for your response.

We recieved an alert J2EE connect failed when listener was down in dual stack.

It means  java instance to Database only or any other connections are there .I just asked that one.

JCmon Shows only running servers. It will not show connections

Can we use tnsping <SID> to check J2EE connect ?

If this is a dual stack then the J2EE stack will work only if the ABAP is up and running.

You need to make sure that the ABAP is working fine.

If the ABAP is up and Java is not starting then check the teace logs in the work directory and also the default traces.

If the listener was down then ABAP will have issues and that will also impact the Java.

J2EE Connect error could be because of the follwoing Reason:-

1. User Locked for Java RFC connection.

2. Java Message Server/Gateway Not Running.

3. Depends on which Java tool you are using for Administration (Sheel Console, NWA, Visual Administration) and its Configurtions.

Also Depeneding on your JCo version, there are different trace files which could give you the  Error..

Hi ,

Please check these senarios...

RFC - Means JCO and SM59...

SSO...

Servenode Satus...

1. RFC created should have checked the radio button 'registered server program' in SM59.

2. check if some restart or instance is down on Java instance.

3. Check in SMGW if program is sapfallback visible here. Goto-> Logged On Clients, here you should be able to see sapfallback entry.

How to check j2ee connect is successful or not?

JCMON before 7.11 now jsmon you can use to check .

What does exactly j2ee connect check ..connection from <where> to <where> ?

it is same thing as r3trans -d in abap. j2ee connect check connection from java instance to database.

Please provide server0 trace we can provide more answers on this.
