    Hello Raj,

    Is this a newly installed system or a copied system? We seethis problem quite frequently where a system has not been copied using the correct method, or if when during the installation the correct listener port number was not specified.

    Please use the confit tool to make sure that the JDBC connection data matches your Oracle Listener configuration.

    Kind Regards,

    David

      Hi Raj,

      Idially, Java part will be invisible from SAP MMC if the installation for ABAP+Java (ofcourse it's possible to have visible with insntallation options available) and the Java part of it is controlled by ABAP start/stop requests.

      Otherwise, If you are able to login to the system (ABAP), please use SMICM where you can check whether Java status, if requir you can go for Java alonoe Restart also.

      Raj, Please give me points if it helps you.

      Thanks

      Chandra
