Hi DBA gurus,
�
I am do a performance test. Find that running same query using tns connection string with SCAN host name is 5 seconds slow than using tns connection string points to a specific host name (17seconds �VS. 12 seconds). Is this normal?� Is there are any special requirement to run�gather schema stats tasks in a RAC environment? Could anyone shed light on these?
�
Thanks,
Lu
