TNSPing to 100% available databases (accessible from other machines, i.e. I can do TNS ping to these databases from other machines) returns me following error: TNS-12535: TNS:operation timeout. At the same time I can telnet to database host/port and see http://dba.stackexchange.com/questions/63251/tns-12535-tnsoperation-timeout that proper tnsnames file is being used. Environment variables are configured as appropriate (ORACLE_HOME, TNS_ADMIN, Path). Also I can connect via telnet using service/host name + port - so this is unlikely a firewall issue. After enabling Oracle client logging I can see following error related details in tnsping.trc: snlinGetAddrInfo: enrty snlinGetAddrInfo: getaddrinfo() failed with error 11001 snlinGetAddrInfo: exit The only strange/suspicious thing about this machine is that it had multiple versions of oracle client installed (10, 11.1, 11.2) - removal of all versions apart from 11.1 & reinstall/repair of 11.1 haven't resolved this issue. Also it seems to me that v10 of client was not removed properly - it disappeared from Programs and Features, but files in installation folder had not been deleted. Any advice on what to check / how to resolve this issue? oracle oracle-11g-r2 share|improve this question edited Apr 17 '14 at 8:40 asked Apr 15 '14 at 14:41 Mikhail 21541017 What is the status of the listener? –Andrew Brennan Apr 15 '14 at 15:27 Not sure how to check this. This is on a client side? I can't find lsnrctl.exe in my client folder... Please provide more details on how to check this if possible. –Mikhail Apr 15 '14 at 15:41 Though I guess

Oracle TNS-12535 and Dead timed out Connection Detection by Svetoslav Gyurov on 31st March 2016 No comments These days everything goes to the cloud or it has been collocated somewhere in a shared infrastructure. In this post I'll talk about sessions being disconnected from your databases, firewalls and dead connection detection. Changes We moved number of 11g databases from one data centre to another. Symptoms Now probably many of you have seen the operation timed out following error in your database alertlog "TNS-12535: TNS:operation timed out" or if you haven't you will definitely see it some day.

It's important to mention that those errors are RESULTANT, they are informational and not the actual cause of the disconnect. Although this error might happen for number of reasons it is commonly associated with firewalls or slow networks. Troubleshooting The best way to understand what's happening is to build a histogram of the duration of the sessions. In particular we want to understand whether disconnects are sporadic and random or they follo
