Dear All,

Today we are getting the following error in our application

ORA-12518: Message 12518 not found; product=RDBMS80; Facility=ORA.

Last two week back I have change the oracle memory set up to autotmatically managed.  I increase the total memory to 2GB and SGA to 900MB (before 700) and PGA 239MB (no changes).  Before it was Archive Mode and no made it to No Archive mode.  Total memory of my HP Server on Window 2003 Server 32 bit.

After this for 2 times in this week we are getting the TNS connectivity error. The allert file copy is below.

Can anyone tell to solve this issue.

Howdy, Stranger!
