    Hi

    I m getting this error.

    Running Oracle 816 on NT 4.0 .
    Processes - 160
    Sessions - 190

    How can i find max no of TNS conectins to database ?

    Oracle says

    TNS-12540 TNS:internal limit restriction exceeded

    Cause: Too many TNS connections open simultaneously.

    Action: Wait for connections to close and retry.

    Most likely it is a resource issue. Do you have enough physical menory and swap space? Is there any OS limitation on concurrent network users?

    Hi,

    RAM on my server is 2 GB.

    Pagefile is of 10 GB.

    No WinNT Err is observed with this error.

    My oracle.exe is taking memory equal to 1.5 GB.

    What to DO now ?

    3 GB Option

    Hi,

    Will enabling the 3 GB option may help me to overcome the problem.


    Or can I go for MTS config ?

    I think you can do either of the following:

    1) Increase value of PROCESSES parameter.

    2) Change to MTS.
