Hi,
Nothing to investigate at the application side, there is everything to investigate at the network side.
Check the below points.
- is there any firewall in play
- is there any Network Address Translation into play
- have the correct ports been opened in the firewall
- is Oracle using random return ports (by default Oracle always uses 2 tcp/ip ports, the first one fixed, and configured in tnsnames.ora, the actual communication takes place on a radom port. If that is a problem at your site you need to fix that)
- You need to run netstat -r to identify which ports are actually used.

    Dear Friends,
    I am using Oracle Apps R12.1.1 and the DB Version is 11.1.0.7
    I am getting the following error in my DB Alert Log:
    TNS-12535: TNS:operation timed out

    Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=172.16.0.9)(PORT=34370))
    I would like to know this error is happening for the client 172.16.0.9?
    Is it related to any server issue? Is it any critical issue?
    Please let me know.
    Regards,
    DB

    Is this error frequently occuring?
    Sometimes due to network disconnection these kind of errors may happen.

  • TNS:operation timed out - on different subnets

    I am having a problem with Oracle on a company’s local network. The problem is manifested by
    TNS-12535: TNS:operation timed out
    error which happens when client repetitively makes connection to Oracle instance located on a different subnet (going via the network backbone). To illustrate this problem I wrote a simple batch file using SQLPLUS. The attached files:
    pingconnect.cmd, this command file executes a single SQL query in an infinite loop :
    @echo off
    :a
    sqlplus -S scott/tiger@oratns @seldual.sql
    goto a:
    seldual.sql - simple query that gets executed in the loop:
    select * from dual;
    exit
    sqlnet.log – error

    When I ran several (for example 7) instances of pingconnect.cmd, it runs for about 3-5 minutes and then fails with error TNS-12535 (see sqlnet.log). This happens with both Oracle 9i and 8i. This only happens when the client and server are located on the different subnets. This is confirmed by a network engineer who worked with me while I was performing tests on various network configurations.
    I am looking for the Oracle network tuning parameters to eliminate this problem. Any suggestions?

    Is it related?I can not say it is related with 100% certainty.
    You can conclude I had a REALLY lucky guess or there is high correlation between VM & having TNS-12535 error.
    It is your system & you are free to (ab)use it any way you choose to do so.
    We both know SQL*Net can & does work as advertised, but requires a properly configured OS & Network underneath it.

  • ORA-12535: TNS:operation timed out on other pc

    After installing the XE edition on a server, I can connect fine on the server itsself. But when I try to connect from a client machine, I get ORA-12535: TNS:operation timed out.
    My tnsnames on the client holds this string for the XE db:
    MyDB.10gXE =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = XE)
    any ideas???

    Rather than
    MyDB.10gXE =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = XE)
    why not go with the bulk standard tnsnames entry as follows:-
    XE =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MYSERVER)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = XE)
    I don't think the qualified MyDB.10gXE name is adding any value and may well confuse things.

  • ORA-12535 TNS:operation timed out from SQLPlus and Enterprise Manager Conso

    I keep getting a ORA-12535 TNS:operation timed out error, when I try to start my Database.
    I know its a timeout error, but I would like to know what is timing out and why. All I want is the database its self to run to allow me to connect to it via SQLPlus and JDBC.
    Is there any information on what the following services do and which ones I need to have running to use the database.
    Oracle OLAP 9.0.101
    Oracle OLAP Agent
    Oracle oraHome90Agent
    Oracle oraHome90ClientCache
    Oracle OraHome90PagingServer
    OracleOra90SNMPPeerEncapsulator
    OracleOra90SNMPPeerMasterAgent
    OracleOra90STNSListener
    Thanks for any help Tony

    Either reconfigure CONNECT_TIMEOUT to be 0, which means wait indefinitely, or reconfigure CONNECT_TIMEOUT to be some higher value. Or, if the timeout is unacceptably long, turn on tracing for further information.
    If you have oracle metalink, then read the following note;

  • ORA-12535: TNS:operation timed out on a win2000 Oracle instance

    Hi,
    i have a Oracle 8.1.5 instance on a WIN2000 PC.
    I can connect me to this database with sqlplus
    as long i stay on the PC (means i started the sqlplus
    on the same machine).
    When i try to connect from an other (unix-)system
    i get after a while (ca. 90 sec.) the error:
    ORA-12535: TNS:operation timed out
    tnsping works fine (answer comes back in one second)
    There are no firewalls or other "strange" things between
    the database and the failing client (on an other PC,
    also win2000, Oracle 8.1.5 everything works fine).
    Below you see the log with debug of the listener.
    I have also a trace on level SUPPORT but this is more
    than 1000 lines for just 1 or 2 TNSPINGs and one SQLPLUS
    connect. Due to this volume i decided not to attach it to
    this initial mail.
    Does any one have some advice or experiences ?
    Please advice.
    Best regards,

    Yes, the XP firewall is running. During the Oracle instalation it poped up twice, but I selected 'Unblock'. I can't turn it off because it is running using the domain settings, but I can add exceptions (programs or ports). Port 1521, tnsping or sqlplus are not blocked and there is an option 'Display a notification when Windows Firewall blocks a program' witch is checked.
