NW04 SR1- missing J2EE_DB_TYPE


I installed Was 6.40 + J2EE addon from the NW04 SR1 disks and all went well. I subsequently ran the EP6 pre-requisite tool and this found a problem with the J2EE Engine. The problem was "Missing J2EE_DB_TYPE".

I have had a look at the system information for the J2EE engine (by going to the J2EE start page and then clicking system information), and this shows:

database name: NULL

database host: NULL

I checked the WAS installation and profiles and everything seems OK. I checked the windows environment variables and these seem OK too. I looked in the SLD and the Java Was is listed; and the SLD has been correctly updated with the system and DB information. I have also been through every pane in the config tool and could not see any place to manually set these variables.

Does anybody know how these variables are set or why the J2EE engine is unable to determine the values for these.

I eventually got EP6 installed by removing the call to determine the DB type and name from the control.xml file and hard coding the values. But I guess that if I don't fix it then it will come back and cause me problems later on.

Hope someone can help.

    I managed to find the answer to this one myself. The reason was that the Java Was install failed to put the following entries in the default profile:




    After I manually entered these parameters and restarted sap everything worked as expected.
