ORA-12547 : TNS lost contact -- Onkar N Tiwary 2005-11-10
I checked for the alert.log also but no error reported there. the problem is errupting when a user is trying to connect to server from the client pc but on the server i am able to connect but that too without using connect string. I was wondering it might be a problem because of the patch as I had told earlier also that before we had been using
without any such error but when we applied a patch on this and upgraded to 126.96.36.199
then we started getting the error. Now after wasting a lot time on this issue, we were in a position to resolve this problem but then we had been another error
ORA-12500 : TNS listener unable to start dedicated server process
now we are planning for the re-installation of oracle using the method :
1. full database export
2. created script to create same tablespace with same users and same password
3. importing the dmp file
Is this method ok?????

Since today morning I am facing one problem :
ORA-12547 : TNS lost contact
when i re-started my server, i worked for couple of seconds and then again i was getting the same error. I searched on metalink which says its a bug which has been fixed in
and 10g and my db is 188.8.131.52
. however we had patched our database yesterday and since then we are getting this error. i reconfigured the listener on different port also but then too same error.
os : win 2k adv. server
