The problem with 10G is it isn't compatible with lower releases. For example if you do a "lsnrctl status" etc. Typically what happens is some monitor program like BMC's Patrol or OpenView issues a command using the lsnrctl from whatever ORACLE_HOME exists for the database it is monitoring. 10G doesn't like that if it isn't a 10G OH. Was wondering if a more elegant/problem-free solution than my soft link exists. Thanks Larry -- //www.freelists.org/webpage/oracle-l
