Oracle TWO_TASK setting and default database logon

Hi,

We are attempting to configure our application with a dedicated Oracle 8.0 database server on a separate Solaris 2.7 host.

We've set the TWO_TASK environment variable to the separate alias name configured in the tnsnames.ora file, and it works fine. All connections are diverted to the dedicated database server.

The problem is that the default username and password logon are disabled as soon as TWO_TASK is set.  Hence, all the supporting shell scripts which use default logon in the form "sqlplus /", or "sqlplus -s /" now fail.  Default logon has been used extensively in our application environment, so this is a major hurdle.

Any suggestions or tips that don't require major rework of the shell scripts would be most welcome.

Thanks

Phillip Prince

The TWO_TASK variable is set so that you can connect to a database thro' Net8 listener without specifying a connect string.

Unless this is your requirement, you need not use TWO_TASK to connect to your database in the first place.  Instead set the ORACLE_SID in your user's .profile.  This is commonly the way to connect locally from the server in which your database is running.

If you have your TWO_TASK variable set and try connecting using OS authentication (/ or OPS$USER), Oracle cannot verify your OS authentication (in Unix member of DBA group) since you are connecting thro' Net8 at this point.
You should then Unset TWO_TASK everytime before you connect using O/S Authentication (and use ORACLE_SID to point to your DB).

Hope this helps..

That's right, good point Ramesh. So before calling the shell scripts:

unset TWO_TASK
export ORACLE_SID=yoursid

Then run the shell scripts as per usual.

Hi, Philip,

Perhaps:

export ORACLE_SID=$TWO_TASK
unset TWO_TASK
