My problem seems to be in starting the oracle management agent. The certification book I am using only explains this process for Unix platforms, not windows.

An interesting side note: when I opened the portlist.ini file, this is what I found;

Ultra Search HTTP port number =5620
Enterprise Manager Agent Port =
iSQL*Plus HTTP port number =5560

Notice that the value for the EM agent port is null.

Attempting to open the Ultra Search or iSQLplus yields the same error. I   believe that we are probably on the right track with the assumption that the missing http service is the issue. Hopefully, someone will be able to guide me on getting that installed soon. Received on Thu Jan 20 2005 - 16:11:59 CST
