environment valuables after upgrade to 11.2.0.2
We recently upgrade a Oracle 10.2.0.4 database to 11.2.0.2. The upgrade went successfully.Right now, we have a task to create a test database on this server with 10.2.0.4.I have set up ORACLE_HOME, ORACLE_BASE, ORACLE_SID, PATH, LIBPATH to point to 10.2.0.4 home. When I use "env", it did show all the environment valuables point to 10.2.0.4 home.However when I run "which sqlplus" , it always show the path of Oracle 11.2.0.2.And once I login sqlplus, and run "!env", all the environment valuables point to 11.2.0.2 home.Have anyone seen this before?What I can do to get it fixed?
