• ORA-12547: TNS: lost contact

  Hello

  That's what I did on my AIX unix server to meet the problem.

  I had Oracle 10 g 10.2.0.4 installed binaries and a DB running on this mobile.

  I got to level it to 11g.

  Downloaded and installed 11.2.0.4 version on the AIX server successfully.

  Updated 10g DB 'mobile' version 11g dbua utility.

  all tested fine and good connections.

  Now the next day today, I have to cleanup and delete the binary 10g of the server.

  And YES I used to clean it.

  Apps/opt/oracle/Products/10.2.0/dB/oui/bin/RunInstaller

  
  

  After this was done, I deleted manually the files of

  RM - r apps/opt/oracle/products/10.2.0

  
  

  Now, I see only binary 11g instead of ORACLE_HOME.

  
  

  I'm trying to connect to the database 'mobile' now, and it gives this error.

  I see my ORACLE_HOME, path of all the other variables are pointing to the correct location of g 11.
  

  I had a smooth ride that follows the blog below.

  I have relinked the executable and was able to start back again Sqlplus session.

  DBA - Oracle.com: how to create a link to the database software Oracle under UNIX

  I'm also pasting the material here, so that it is useful to others.

  with an Oracle installation program provided.

  -A set of patches Oracle has been applied via an Oracle supplied Installer.

  Reissue of links manually Oracle suggested in the following circumstances

  (even if the OS vendor can not required):

  -An upgrade of the OS has occurred.

  -A change was made to system OS libraries.  This can occur when you apply a patch to the BONE.

  -A new installation has failed during the relinking.

  -An individual Oracle patch has been applied (However, to recreate an explicit link

  instructions are usually included in the Readme or integrated

  the hotfix installation script)

  Step of restoring links:

  [Step 1] Log in the UNIX system as the Oracle software owner:

  ==============================================================================

  This is usually the user 'oracle '.

  [STEP 2] Ensure that your $ORACLE_HOME is correctly set:

  ===============================================================================

  For all platforms and the Versions of Oracle, performs this check of the basic environment

  first:

  % cd $ORACLE_HOME

  % pwd

  This will ensure that $ORACLE_HOME is set properly in your current environment.

  [Step 3] Check and configure the UNIX environment for a reissue of appropriate links:

  ===============================================================================

  For all Versions of Oracle and UNIX platforms:

  Generally, the specific environment variables of platform LIBPATH, LD_LIBRARY_PATH and SHLIB_PATH are already defined to include the locations of library of the system as "/ usr/lib.  In most cases, you need only check they are defined first, and then add the directory of $ORACLE_HOME/lib to them as appropriate.

  for example: setenv LD_LIBRARY_PATH $(ORACLE_HOME) / lib: ${LD_LIBRARY_PATH}

  [Step 4] For all Versions of Oracle and UNIX platforms:

  ===============================================================================

  Make sure you have correctly completed the step 2:

  Make sure you see the absolute path for

  $ORACLE_HOME in the definitions of variables.

  [Step 5] For all Versions of Oracle and UNIX platforms:

  ===============================================================================

  Check the umask is set correctly:

  umask %

  This should return a 022.  If it is not the case, the value of umask 022.

  % umask 022

  umask %

  [Step 6] Run the OS in question Oracle commands:

  ===============================================================================

  Important notes:

  * Before the restoration of the Oracle links, close the database and listener.

  Following commands out lots of text in the window of your session. To capture this release for download in support, redirect the output to a file.

  * If the re-establishment of links an installation of the client, it is expected that certain aspects of the following commands will fail if the components were not initially installed.

  For all UNIX platforms:

  Oracle 8.1.X, 9.X.X, 10.X.X or 11.X.X

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

  NEW TO 8i AND MORE *.

  A "reissue" script is provided in the directory $ORACLE_HOME/bin.

  % cd $ORACLE_HOME/bin

  relink %... .This will display all the options for the command.

  use: re-edit the link

  accepted parameter values: all, oracle, network, client,.

  interMedia, precomp, utilities, oemagent, client_sharedlib, ldap

  You can bind again most of the executable that is associated with an Oracle Server Installation

  by running the following command:

  % to reissue all the

  11.2.x special instructions (11.2.0.1,11.2.0.2 etc...)

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

  (A) starting at 11 GR 2 the script to repeat will not accept 'everything' as argument (it is also

  explained in: Oracle 11 g 2 connect new feature).

  See c) the traditional 'make' commands that can be executed independently.

  You can use the following command which will display only errors to the screen, as appropriate,

  but will capture the entire repeat the link in a log file:

  $ORACLE_HOME/Yes/bin/runInstaller - reissue - waitForCompletion - maketargetsxml $ORACLE_HOME/inventory/make/makeorder.xml.

  ORACLE_HOME = $ORACLE_HOME 2 > & 1 | Tee $ORACLE_HOME/install/relink.log | grep-i error | WARNING - iv grep

  (C) running the commands ' do ' independently:

  For executables: oracle exp, imp, sqlldr, tkprof, mig, dbv, orapwd, rman,

  svrmgrl, GMO, ogmsctl

  % cd $ORACLE_HOME /rdbms/lib

  % make install f ins_rdbms.mk

  NOTE: After the restoration of the links the oracle executable, make sure that the

  permissions on executable are 6751 (- rwsr - s - x). If they are

  not, run the following command as the Oracle software owner:

  % cd $ORACLE_HOME/bin

  % chmod 6751 oracle

  For executables: sqlplus

  % cd $ORACLE_HOME/sqlplus/lib

  % make install f ins_sqlplus.mk

  For executables: isqlplus (Oracle9i and above)

  % cd $ORACLE_HOME/sqlplus/lib

  % is install_isqlplus ins_sqlplus.mk f

  For executables: dbsnmp, oemevent, oratclsh

  % cd $ORACLE_HOME/network/lib

  % make install f ins_oemagent.mk

  NOTE: After the restoration of the links the dbsnmp executable, it is necessary to run

  the following commands as root (so that the ownership/permissions on)

  the executable file is correct):

  # cd $ORACLE_HOME/bin

  # chown root dbsnmp

  # chmod 6750 dbsnmp

  For executables: names, namesctl

  % cd $ORACLE_HOME/network/lib

  % make install f ins_names.mk

  For executable files: osslogin, trcasst, trcroute, onrsd, tnsping

  % cd $ORACLE_HOME/network/lib

  % make install f ins_net_client.mk

  For executables: tnslsnr, lsnrctl

  % cd $ORACLE_HOME/network/lib

  % make install f ins_net_server.mk

  
  How to Tell if Relinking was successful:

  ===============================================================================

  If the restoration of links has been a success, order brand will eventually return to the operating system

  ask without an error. It will NOT be a type 'successful rebinding.

  Message.

  If you receive an error during the reissue of links:

  ===============================================================================

  Check that the message that you have received a fatal error itself says, not a warning. Reissue of links errors usually complete the relinking process and contain the verbiage that is similar to the following:

  "Fatal error", "Ld: fatal', 'Exit Code 1'"

  While the warnings will look like: ' ld: WARNING: choice - YP appears more than once, first affecting decision-making '

  and more often can be ignored.

  If you receive an error that terminates the process of relinking, your first step

  should be to extract the relevant information about the error to do

  output:

  This can be broken down into three basic steps:

  1. determine the usefulness of the BONE that returns the error.

  'ld', 'make', 'cc', 'mv', 'cp', 'ar' is the common sources.

  2. identify the type of error:

  "Permission denied", "Undefined Symbol", "File not found" are common types.

  3. identify the files or the involved symbols.

  I searched MOS (Metalink) and also reviewed a few sites using Google. All the information indicates that this problem most often occurs when you try to connect to an existing database using sqlplus. I have not found that everything about this error message when the database was created.
  
  Does anyone have advice on how to troubleshoot the problem? Can you point me to some documents that could help with this issue?

  In which group is the user to network?
  What group you chose in the group administrator of the ASM?
  Authorities who have your oracle executables (in the House of the grid and Oracle Home)?

  If you cloned Oracle Home, then it is very likely that the oracle Oracle executable Home is owned by oracle: oinstall, but it must be owned by oracle: asmadim (or prabably s/n) in your case.

  Use setasmgidwrap on the oracle executable in the House of the Oracle and this should solve your problem.
  (DBCA imlicitly calls it).

• ORA-12547 TNS LOST during the 12 c dbca on grid infrastructure.

  Hi all

  In my test environment, I installed the 12.1.0.1 9 VMware and REDHAT 6.4grid infrastructure. After a successful installation of the grid infrastructure and database binary when I try to create the database with dbca, show me ORA-12547 TNS LOST.

  Installation is 2 node grid infrastucture ASM on shared disk. Using binary grid and oracle grid and database users respectively.

  I searched forum and METALINK also, I got a part the documents below.

  1. doc ID 1069517.1 : it says to check the permissions on the files binary oracle as below. I thought it was ok.
  

     - rwsr-s - x 1 184286251 9 August 16:25 /home/oracle/app/oracle/product/11.2/db/bin/oracle asmadmin oracle

  
  

  2 many docs suggested to check libaio-*. rpm. I found that libaio x86_64 RPM is installed but libaio i686 rpms were missing. I installed them also.

  
  

  But still, I get the error.

  Please suggest.

  Kind regards

  Hi gurus,

  I am puzzled to this problem, no one else is having problem connecting to the database except a user who always gets "ORA-03135: connection lost contact" when you try to connect to the test and Prod environment.

  Get the same error when you try to connect via EDIVIEW (application) or the prompt of commands or cygwin terminal directly.

  tnsping works fine and return connect credentials

  Here's what I did troubleshooting:

  1. make sure that the user is not locked in the database

  2. place the database restricted and provided this user mode access restricted and tried the connection as long as that user, not luck.

  3A bounced the listener

  4A rebounded from the database

  5. some online forums suggest to increase the timeout setting in sqlnet.ora, in our environment, we use the OID and the sqlnet.ora is the central directory. If this cannot be the issue that everyone can connect.

  6. I checked the sqlnet.log file and there seems to be no incoming connection from this user or machine.
