Platform: Sun Solaris
DB Version: 188.8.131.52
I see a delay of of 10 to 15 seconds before the SQL> prompt appears when I connect to using the following statement:
$ sqlplus /
I have checked to make sure that oracle tracing is not set, and I verified in the $ORACLE_HOME/otrace/admin directory, and there are not .dat files existing.
I am not sure why it takes so much delay on this database alone, while it takes only 2 to 3 seconds to connect to other databases.
I even tried tnsping and the response is less than 10 ms.
Any help would be much appreciated.
How long time does it take to connect via FTP? If long, then the problem might not be within Oracle.
You may try to to transfer the listener to another port. Before doing that however, check that you use the IP address of the database server in the listener.ora and tnsnames.ora files, check that tracing is not on (for the listener, SQL*Net too).
Try to flush the shared pool: ALTER SYSTEM FLUSH SHARED_POOL; and add log_directory_client='null' to sqlnet.ora.
If in tnsnames.ora set NAME of server:
1) Try to set IP address to Oracle server directly
2) Try type server name using full dot notation aaa.bbb.orsserver
Check firewalls and proxy servers if they exists.
Check tracerout from client box to oracle server.
