RE: Significance of TWO_TASK

TWO_TASK is like ORACLE_SID, but it directs Oracle clients to resolve via TNS rather than looking for that SID directly via BEQ.

So, if my SID is TEST on the local machine, and I do:

$ export ORACLE_SID=TEST
$ sqlplus system/manager

I will connect to the instance with a SID of TEST on the local machine. But if Oracle is running on a remote machine, and I set up TNS name "TEST" (in tnsnames.ora) for it, then try those commands, it will fail, even tho'

$ sqlplus system/manager_at_TEST

will succeed. However, if I then do

$ export TWO_TASK=TEST
$ sqlplus system/manager

It will work as expected - the client will take the TNS name "TEST" to be its default instance, and connect via TNS.

HTH, g
