Question

New session to database are refused by the listener TNS-00510 and TNS-12500

Asked by: rateesh



Hai guys,


I am facing some problem with my database Oracle 8.1.7 running on windows 2000 service pack 2 .The server has Physical Memory of 2 Gb Ram . Now to the problem, new connections to the database are someties rejected giving the following error

  TNS-12500: TNS:listener failed to start a dedicated server process


the listener log file gives the following error

==============================================================================
TNS-12500: TNS:listener failed to start a dedicated server process
 TNS-12540: TNS:internal limit restriction exceeded
  TNS-12560: TNS:protocol adapter error
   TNS-00510: Internal limit restriction exceeded
    32-bit Windows Error: 8: Exec format error
==============================================================================


this is happening randomly and at time of high CPU activity. I went through some oracle docs and it said that it could be due to lack of resources or memory .I guess that new session could not be started by the listener. Task manager shows that around 1.9 gb of ram is being used.


Around 180 sessions access the database through out. sharedpool is set to 385 MB Buffer cache is 400 Mb Sort_area_size is set to 2 Mb.
Processes parameter is set to 220.


Thanks in advance
