Hi All, I am facing strange problem, I installed 9i and 11g on same machine whiche is runng windows server 2003 service pack 2. I set ORACLE_HOME and PATH of both versions different and both are installed properly. But when i try to create new database using oracle 9i DBCA after reaching step 8 DBCA becomes unresponsive whereas i am able to create new database using Oracle 11g DBCA. After searhing the entier net i am not able to trubleshoot the problem.Moreover in both version i am able to access using CMD and i got the connectivity. I configure the listener for both on different port but when i run oracle 9i the screen shows first connectivity of oracle 11g sql* plus after that it is going to connect to oracle 9i this is my second issue. My system is having 1GB of RAM Please guys take this problem on high priority. Thanks in advance.
