Database refuses connection

edited Apr 9, 2012 4:45AM in Database Networking (MOSC) 4 comments

Hi,

I am using Oracle 8.0.6, Win Srv 2003 (32-bit). The server has 12GB RAM, but utilizes less bcoz of 32 bit.

I am facing a strange situation now a days. Sometimes the users cannot connect to the database if the no of sessions reach 420+. We have set the limit for max sessions around 555. When i faced this situation, i got the below error file on my pc.


Fatal OSN connect error 12547, connecting to:
 (DESCRIPTION=(CONNECT_DATA=(SID=ORCL)(CID=(PROGRAM=TOAD.exe)(HOST=ATIQ)(USER=Ateeq)))(ADDRESS_LIST=(ADDRESS=

(PROTOCOL=ipc)(KEY=GNP.WORLD))(ADDRESS=(COMMUNITY=tcp.world)(PROTOCOL=TCP)(Host=134.50.X.X)(Port=1521))(ADDRESS=

Howdy, Stranger!
