Oracle ora-12545 error

Hello
I have a problem to connect my database
error ora-12545 Connect failed because target host or object does not exist
I checked the forums for similar error
tried all the recommendation as
Check the file hosts, ping server... but nothing

My connection is like that
I have a server of db oracle on a RHEL 5.4
I have a client oracle on an other RHEL 5.4

I tried to connect to the Database via the client, but it does not work
I have configured my connection string (orcl)
tnsping work: tnsping orcl
Still I can't connect to the db Server

Here is something else
When I type sqlplus that comes from the command prompt
username
After the password
and then I had error ora-12545 connect failed because target host or object does not exist

but

When I connect like this: user/pass@orcl
it brings me to the shell prompt without giving error *.
as it connects and disconnects just after

Are there any newspaper I should enable or check?

What should be done to fix this?

Any idea would be appreciated?

Thank you

What do you see in the strace output file that corresponds to the time when SQL * younger disappear?

You can view the last 100 lines or more of the file?

In addition, you use an AMD processor on this system by chance? The reason why I ask is because of the following My Oracle Support note:

ORA-24550: SQL * Plus Client 32-bit can hang on a Linux X 86 - 64 OS with processor AMD [ID 1120724.1]

However, we have not seen any messages associated with this question in one of your outings, so may not be relevant at all.

    Hello

    I realize that your problem is that 10.2 HSODBC was never focused on the Windows 64-bit platform and was only available on 32-bit Windows.  You can not install the 32-bit on WIndows 64-bit HSODBC.

    Your only option is to install 11.2 DG4ODBC on your platform Windows 64 - bit, or if you have a RDBMS 10.2 installed on another platform, then you could use HSODBC as part of this installation and connect from the RDBMS on Windows 64 - bit using the links in the database.  HSODBC 10.2 software could not be installed as a stand-alone product and was only available as part of an RDBMS install.

    Kind regards

  • ORA-12545 alert.log anti spam

    Hello

    Windows 2008 server x 64

    Oracle 11.2.0.3 x 64

    Client reported the response time very slow with the database; especially with the initial connection to the database. STATSPACK reports do not seem to show anything unusual. What is good, and it may or may have an effect on the performance of the connection, is an abundant amount of ORA-12545 error in the alert.log from the database server, so much so that since May 1st the alert.log won 300 MB in size for this single error! Precise moments show messages in the listener.log but this newspaper does not provide any error and said just that the connection has a flag "establish".

    Couple questions

    1. Within the messages it says "Tracing not lit not." - which trace must be activated and how I can further debug?
    2. When the search for the error number, it seems that this message should be on the client side and not in the alert.log to database. This makes me believe that perhaps the database trying to make connections to some other db or similar and generates this error because the tnsnames.ora servers cannot be configured for such connection. My premise is false?

    Here is the full error:

    Same mistake.  Nothing is written for the journal of alerts.  IM starting to pull the hair is left on my head out and people start screaming for this database.  I could go back to datapump but I want to understand this.  Any help would be very much appreciated.

    Thank you.

    Yes, although this:

    connected to target database: IST_11G (DBID = 525645852)

    connected to the auxiliary database: IST_11G (unassembled)

    can say you that RMAN you connected the two separate databases, the process, instances should do research each other using tnsnames file entries.  Thus, incorrect tnsnames entries can have one instance pointing to itself.

    This problem started recently, and I understand that it is because of the dynamic ip of the linux machine. Previously the Linux m/c ip was 172.25.210.177 unfortunately was launched once the machine ip has changed in 172.25.210.148.

    To bring the database up I started as usual and got to the top, but when connecting db with the above error is being username/password@orcl.

    To solve the i changed the ip address in tnsnames.ora and listener.ora but no luck. Please advice how to solve.

    It will run until the next change of the ip address. If you want a permanent solution, you must assign a static ip address. Why is your dynamic ip address? What is a local testbox.foobar.com or a production system that must be accessible to other systems?

    I did not read the answer #7 until at the latest. Anyway, I was able to connect and what you said is correct.

    I ran the following command and was able to connect:

    ALTER DATABASE OPEN CONNECTABLE TO ALL;

    Thanks for all the help. This question is answered.

    Guys, there are 2 databases installed on the same server, to correctly configure the SID. Once set, I could see that the database is down and when starting it started working well.

    OK, so you have a software firewall (IPTables) running.  By default, it will not be configured to accept connections on port 1521.  You have two options...

    (1) disable the firewall completely.  Run these commands to do this...

    stop /etc/init.d/iptables

    chkconfig iptables off

    The first command stops the service.  The second command prevents revived at every restart of the OS.

    (2) add an exception to the firewall for port 1521.  I'm not a Linux expert, but it should be something like this...

    Change the configuration of IPTables with vi...

    VI/etc/sysconfig/iptables

    Add a new rule as follows...

    -A of ENTRY m state - state NEW-m tcp tcp - dport 1521-j ACCEPT Pei

    Save and close, and then restart the IPTables service...

    /etc/init.d/iptables restart

    NOTE: you must always change the name of this server to something other than "localhost".

  • Unable to connect to the remote computer (ORA-12545) DB

    Hi all

    Need help please, I'm stumped.  I am trying to connect to a database that is located in my work from home.

    I'm running into the following question (see the command and the error below):

    )

    )

    -------------------------------

    I checked that I can establish a TCP connection to the DB server on the specified port, using the same information in the file TNSnames.ora (see below):

    -------------------------------

    ansichart@ansivm:~/src/perl$ nmap - sT Pei 1521 orarac9-scan

    -------------------------------

    I have another terminal opens to a server at work and I can connect to the DB with sqlplus very well.  I checked the record for this database on the tnsnames.ora file is the same as it is at work.

    In conclusion, I can connect to the database to work, but I can't go home, even if I am using the same connection information and verify that port 1521 is available on this database from home server.  So why can't a DB connection?

    Any ideas?

    Thank you

    It simply means "Unknown host name." In other words, the hostname used for the connection could not be resolved to an IP address.

    I checked that I can establish a TCP connection to the DB server on the specified port, using the same information in the file TNSnames.ora (see below):

    You check hostname orarac9-analysis only. You do not check that the hostname provided by the Oracle SCAN earpiece can be resolved by your platform.

    That you connect to a listener to SCAN, it will do its magic (balancing/alternate/whatever) and return, the customer asked the name a redirect to your client driver - he tell where to find the service.

    If the driver of your client gets a host name and port in return. He then tries to connect to that to establish your Oracle client-server session. If the RAC has been implemented with FCAC's typical host names, your customer will get names like vip1-orarac9 and orarac9-vip2 returned. Probably as FULL domain name too.

    This means that your platform must be able to resolve these host names. This isn't. Thus the error.

    In the file/etc/hosts of your platform, define the list of hostnames (hostnames SCAN, Public and VIP) CARS.

  • Clients unable to connect due to the ORA - 12545 Intermittent in RAC environment

    We deal with this problem.
    Whenever we connect customer oracle application to our database server.
    ounces it connect and the next moment, it shows the error ORA-12545: Connect failed because target host or object does not exist.

    After searching on Google, I found many recommendations for this.
    the one I like is:

    +(source: Internet) +.

    Whe LOCAL_LISTENER is nothing or is not set correctly, PMON can record the VIP host name and the physical hostname with the REMOTE_LISTENER. This is incorrect in the CARS, but if this happens, the client may intermittently be routed to an endpoint listens on one of these addresses. If the client cannot resolve the host name physical or even vip host name, the connection will fail with ORA-12545.
    And first set is important to check the output for: lsnrctl services < nom_recepteur >
    You should not see the physical hostname in the information manager for your RAC instances. Here is an example of a services of incorrect lsnrctl < nom_recepteur > output to a 2 node RAC cluster:
    oracle_rac_listener lsnrctl services
    Service 'oracle.oracle.com' has 2 occurrences.
    'Orcl1' instance, State LOAN, has 2 managers of this service...
    Managers:
    "DEDICATED" set up: 0 denied: 0 status: ready
    REMOTE SERVER
    (ADDRESS = (PROTOCOL = TCP)(HOST=myphysicalhost1) (PORT = 1521))
    "DEDICATED" set up: 326 refused: 0 status: ready
    LOCAL SERVER

    "Orcl2", State LOAN, has 1 operation for this service...
    Managers:
    "DEDICATED" implemented: 394371 refused: 0 status: ready
    REMOTE SERVER
    (ADDRESS = (PROTOCOL = TCP)(HOST=myphysicalhost2) (PORT = 1521))
    Here's an example of what it should look like when LOCAL_LISTENER is configured correctly:
    oracle_rac_listener lsnrctl services
    Service 'oracle.oracle.com' has 2 occurrences.
    'Orcl1' instance, State LOAN, has 2 managers of this service...
    Managers:
    "DEDICATED" set up: 0 denied: 0 status: ready
    REMOTE SERVER
    (ADDRESS = (PROTOCOL = TCP)(HOST=myVIP_host1) (PORT = 1521))
    "DEDICATED" set up: 326 refused: 0 status: ready
    LOCAL SERVER

    "Orcl2", State LOAN, has 1 operation for this service...
    Managers:
    "DEDICATED" implemented: 394371 refused: 0 status: ready
    REMOTE SERVER
    (ADDRESS = (PROTOCOL = TCP)(HOST=myVIP_host2) (PORT = 1521))
    Open a session with privileges to the instance and run the following commands so that LOCAL_LISTENER is correctly configured:
    change the value system LOCAL_LISTENER = "(address = (protocol = tcp (host = < your_vip_node1 >))(port=1521)) range = the two sid ="INSTANCE_NAME1";"
    Do the same for the 2nd instance where is set to < vip_host_node2 > and the sid is defined for the 2nd instance name.
    change the value system LOCAL_LISTENER = "(address = (protocol = tcp (host = < your_vip_node2 >))(port=1521)) range = the two sid ="INSTANCE_NAME2";"
    Now the correct address using the VIP host name is registered against the Auditors in the cluster.
    The client must be able to resolve all forms of the VIP host through their file/etc/hosts. that is, short name and complete.


    now my concern is:

    To change the LOCAL_LISTENER parameter in the init.ora/spfile database, it will require a downtime? or it will have a negative impact on our existing RAC databases?
    Please suggest?

    Thank you
