ABAP+JAVA - Java-addon does not seem connected

[Former Member]

Hi,

I messed around with this new system a month ago and now that I finally got back to it the JAVA part don't seem to be working or the SCS instance is not connected to the Central Instance.

The SCS instance seems to be running fine.

Some questions:

1. In t-code SM51, should you be seeing any reference to the SCS/JAVA instance?

2. The <b>Central Instance number is 08</b>. The S<b>CS number is 10</b>. So I should be able to connect to the java part by browsing to http://hostname:51000 or not? (I get a page cannot be displayed)

3. When I for example trying opening the Solution Manager Diagnostics from the SAPGui the Internet Explorer window that opens try to browse to http:/hostname:8008/xxxxxxxxx . Should it not go to port 51000?

4. Is it correct that the Default parameter rdisp/msserv_internal = 2008 and that the SCS instance one = 3910?

5. Any other advice or ideas on how I can troubleshoot this?

Many thanks!

Hi,

some answers:

1. No

2. no. On the Java SCS only Java Message Server and Java Enqeue Server are running. Try http:/host:8108/msgserver you should get an answer from the Java Message Server because its http port is 81$$

3. not neccesaryl. In an ABAP+Java System the ICM distributes HTTP request between ABAP and Java world. 80$$ is the default http port if ICM. Without any URL prefix the ICM should redirect to the Java Dispatcher. When the URL has a prefix starting with sap, e.g. http://host:8008/sap/public/info its going to the ABAP side.

4. you find default ports at http://service.sap.com/security > Security in Details > Infrastructure. There should be a pdf called TCP/IP ports used by SAP software or something similar.

5. what do you want to troubleshoot? Everything seems to be fine
