    purging active data from change table

    Hi,
    I want to purge a change table for those data for which the subscriber has not been able to call PURGE_WINDOW. Now is it possible ? tehn how?

    I know that a change table can be forcefully dropped while active subscribers still exist
    by using the force option of DBMS_CDC_PUBLISH.DROP_CHANGE_TABLE

    Now Can I purge forcefully those data for which subscriber do not call purge_window ?
    otherwsie the size of the change table gets growing since not calling of purge_window.

    Using which script can I install JVM and how to check whether that is installed or not?

    Regards

    Deba

    Hi,

    To install JVM,

    run initjvm.sql script in $ORACLE_HOME/javavm/install directory.
    you have many other scripts in the same directory connected with java.

    To check whether its installed properly

    SELECT Count(1)
    FROM dba_objects
    WHERE object_type Like '%JAVA%';

    this query will return more than 4000 rows,

    To remove JVM run rmjvm.sql

    Hi,

    Dont know about the purging problem.

    "If initjvm.sql executed properly, the total count of Java schema
    objects should be greater than 8,000,"

    Sorry i said 4000
