JControl fails at start

[Former Member]

We just added a dialog instance on a new server, sapinst runs all the way through, but fails because it cannot start the instance.

This is the trace file for dev_Jcontrol.

I do remember this is kind of a false error, because all of the java settings are correct. Can anybody help us with this?

Perry,

Is your JAVA_HOME environment variable set correctly in all locations? You should add the jre path (d:\usr\java\bin) to the system path variable.

<i>Cannot find Java compiler [d:\usr\java\bin\javac.exe].</i>

Yes, the following has been set:

SAPINST_JRE_HOME = D:\usr\java

JAVA_HOME = D:\usr\java

Appended to PATH: D:\usr\java\bin

Ah, but HOW did you set them

Make sure they are System variables (the lower frame of Environment Variables screen), and not User variables (the top frame).

Been there, done that, got the t-shirt.

Well, believe it or not, it had nothing to do with java path, it was a permissions issue. I went back to the install docs. it said that SAPService<SID> should not be a member of domain users and its primary group should be SAP_<SID>_GlobalAdmin. I made the changes, and "VIOLA", it started....

Hi Perry,

See if this helps :

The engine is not able to start due to problems detecting the JDK.

<b>1.</b> Check that you have installed the correct JDK version. Read the section entitled 'Confirmation of the VM in use' in Note 943498 to find the appropriate platform-specific note.

To identify the current version of the JDK, execute the following command at command line level:

java -version You must have installedthe complete JDK/JSDK (including the Java Compiler javac).

<b>2.</b> Check if there are redundant JDK versions and make sure that the SAP J2EE Engine uses the correct JDK version. Therefore, <b>verify thecorresponding parameter in the instance profile

/usr/sap/<SID>/SYS/profile/<SID>_JC<num>_<host>

jstartup/vm/home = <jdk home directory>.

This parameter has a higher priority than the environment variable JAVA_HOME. </b> - On Unixsystems, it is important to verify the user rights.

If you experience problems with the JDK, open a message under the component for the relevant JDK provider (for example, BC-OP-SUN-JSE).

Thanks,

Sai Kondapi.
