• Need help bridge database for MS SQL Server, error ORA-28546 configuration problems

  Dear all,

  I'm trying to configure Oracle to MS SQL Server(I don't have admin access to the MS SQL Server) database gateway.  When I try to test the dblink connection, I get the following error.

  I published select * from dual@xyz;

  ORA-28546: initialization of the connection failed, probable Net8 admin error

  My setup is as follows.

  1 oracle 11 GR 2 under Oracle Linux 6, the same gateway version is installed on the same server but different base directory.

  2 oracle DB base directory is u01/app/oracle/product/11.2.0/dbhome_1, gateway home directory is/u01/gateway.

  With this info, I rechecked the listener and saw that you are missing the ORACLE_HOME setting in the dg4msql section of SID. Please correct your entry to mssql_sid to:

  SID_LIST_LISTENER =

  (SID_LIST =

  (SID_DESC =

  (GLOBAL_DBNAME = db.abc.com.tw)

  (ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)

  (SID_NAME = orcl)

  )

  )

  (Program name = / u01/gateway/bin/dg4msql)

  )

  )

  Then please stop and restart the mssql listener and check again.

• After changing the port (1521 to 1525 in listener.ora and tnsnames.ora) OEM: the database is down

  Hello

  I'm installing Oracle Database 11 g 2 (11.2.0.4) on Oracle Linux 7.1.

  In short, what I'm trying to do now is changing the default port of 1521 to 1525.

  So I stopped the listener (lsnrctl stop) and then changed my listener.ora and tnsnames.ora:

  Listener.ora

  listener.ora # Network Configuration file: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

  # Generated by Oracle configuration tools.

  LISTENER =

  (DESCRIPTION_LIST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))

  )

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP (PORT = 1525))(HOST = localhost))

  )

  )

  ADR_BASE_LISTENER = / u01/app/oracle

  tnsnames.ora

  tnsnames.ora # Network Configuration file: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

  # Generated by Oracle configuration tools.

  BI =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP (PORT = 1525))(HOST = localhost))

  )

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = bi)

  )

  )

  And then changed the local_listener:

  SQL > ALTER SYSTEM SET LOCAL_LISTENER = "(ADDRESS = (PROTOCOL = TCP)(HOST=localhost) (PORT = 1525))";

  SQL > ALTER the REGISTRY SYSTEM;

  Finally, I started the listener (lsnrctl start) again.

  Then I tried to connect using Oracle SQL Developer to the customer. The port of 1525 works perfectly well.

  The problem is, when I open the OEM (Oracle Enterprise Manager), it says: "the database is down. Please specify the credentials of the host to access the restart and database diagnostic tools," which is like this: http://imgur.com/oKLPW65

  So I logged on the account of the host, and it shows that the database instance, listener and the agent is all down like this: http://imgur.com/Bzr84bz

  It seems that the port used by the OEM is always 1521.

  What should I do? Can someone help me solve the problem?

  Thanks in advance.

  UPDATE:

  After changing the emoms.properties & the targets.xml (thanks to Elisabeth), you will need to reconfigure dbconsole using emca.

  So what I'm doing is decreasing the config:

  $ emca - deconfig dbcontrol db-rest drop

  and then create again:

  $ emca - create config dbcontrol db-rest

  Voila.

  Best regards

  Jerry Antonius

  Hello

  Try to change the port numbers in the following files

  Don't port no 1521 to 1525

  $ORACLE_HOME /_SID/sysman/config/emoms.properties

  oracle.sysman.eml.mntr.emdRepPort = 1525 (before 1521)

  $ORACLE_HOME /_SID/sysman/emd/targets.xml

  (Before 1521)

  (Before 1521)

• Directives IFILE in tnsnames.ora give seemingly harmless errors

  I have a tnsnames.ora file on my local machine that contains a number of directives IFILE, that seems to cause a lot of errors in logging in SQL Developer Page (I use 1.5.4, but the behavior has been consistent since the beta releases).
  
  My tnsnames.ora file is just a pointer to other files tnsnames.ora, i.e.
  

  # tnsnames.ora Network Configuration File: c:\oracle\product\11.1.0\client_1\network\admin\tnsnames.ora
  # Generated by Oracle configuration tools.
  
  IFILE = c:\oracle\product\11.1.0\client_1\Network\Admin\tnsnames.ora.project1
  IFILE = c:\oracle\product\11.1.0\client_1\Network\Admin\tnsnames.ora.clientFoo

  This makes it easier for me to have the client or project specific TNSNames.ora files can I share (or borrow) to other people without having to manually edit a giant single file which combines information from several clients.
  
  Everytime I open SQL Developer, I get an error in the Page log at the bottom of the screen for each entry IFILE where
  
  Level = SEVERE
  Sequence = 53
  Elapsed = 63
  Source = oracle.dbtools.raptor.utils.TNSHelper
  Ifile = message not found c:\oracle\product\11.1.0\client_1\Network\Admin\tnsnames.ora.project1
  
  As far as I know, this is no problem for me - I can connect with happiness to all databases. Of course, I'd like to be able to avoid generating all these errors every time.

  Hi Justin,

  I see the error when it is unable to load the file because space.

  It looks like a problem with trim white space:
  works for me (no space after the =): IFILE = / home/turlochcurrent/separation/tmp/testtnsnames/dontfindme
  does not work for me (extra space after the =): IFILE = / home/turlochcurrent/separation/tmp/testtnsnames/dontfindme

  which is buggy/fixed easily if you can confirm that this workaround works around your question.

• When I need the machine tnsnames.ora and customer configurations?

  Hello
  
  I installed Oracle 11 g on Linux system and successfully created the databases. I can access the database (on server) Enterprise Manager and SQL * (by sqlplus SYSTEM/pass@ora). On another computer I installed the Oracle 11 g database Client (and chose the type administrator installation). Before you start the network for local configuration Setup Wizard Net Service Name, I started Enterprise Manager (the same address, what happens on the server). I was very surprised that I can access Enterprise Manager client without any additional configuration.
  I know, tnsnames.ora help with SQL * more (we can access SYSTEM/pass@ora and don't give no address ip and port).
  And my questions: can I access by Enterprise Manager of any client computer without creating tnsnames.ora and additional configurations client machine?
  Is SQL * more use only tnsnames.ora?
  
  Thanks awfully for help.

  Luk004 wrote:

  Yes, because the Business Manager is an application of 3 layers: you connect to an application server that connects to the database instance.

  Luk004 wrote:

  No.: each client must connect directly to the instance of database with a base layer Oracle Call Interface (OCI) must use tnsnames.ora.
  There are a few exceptions:
  -The thin JDBC driver: http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14251/adfns_environments.htm#sthref52.

• What configuration must define in tnsnames.ora

  Dear all,
  
  Need your help. I have zero knowledge in oracle. Now, I need to conenct to the Oracle database from my window via SQLPlus server, which configuration should I set in my tnsnames.ora? A or B?
  
  Set A
  PNTP =
  (DESCRIPTION =
  (LOAD_BALANCE = on)
  (FAILOVER = on)
  (ADDRESS_LIST =
  (SOURCE_ROUTE = yes)
  (ADDRESS = (PROTOCOL = TCP) (HOST = Hostname1)(PORT = 1521))
  ((ADDRESS = (PROTOCOL = TCP) (HOST = Hostname2)(PORT = 1521)))
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = pntp)
  )
  )
  
  Series B
  PNTP =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP) (HOST = Hostname1)(PORT = 1521))
  (ADDRESS = (PROTOCOL = TCP) (HOST = Hostname2)(PORT = 1521))
  (LOAD_BALANCE = yes)
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = pntp)
  )
  )

  How can i make sure the pointer are D:\oracle\ora92\network\ADMIN and not another folder? Can check from "environment variables "? WHich part?
  

  I suggest you go back to the documentation and reading.
  Please look at the following:

  http://download.oracle.com/docs/cd/B19306_01/install.102/b14312/post_install.htm#CHDBIHEE
  
  Then, on each client computer, configure either of the following settings:
  
      *
  
        Set the TNS_ADMIN environment variable to specify the location of the tnsnames.ora file and specify a service name from that file.
      *
  
        Place the tnsnames.ora file in the ORACLE_BASE\ORACLE_HOME\network\admin directory, and make sure that the ORACLE_HOME environment has been set to this Oracle home.
  

  Your tnsnames.ora file should contain the following, assuming that you have (n) number of nodes:

  PNTP =
  (DESCRIPTION =
  (LOAD_BALANCE = on)
  (ADDRESS_LIST=
  (ADDRESS = (PROTOCOL = TCP)(HOST = Hostname1-vip)(PORT = 1521))
  (ADDRESS = (PROTOCOL = TCP)(HOST = Hostname2-vip)(PORT = 1521))
  .
  .
  .
  (ADDRESS = (PROTOCOL = TCP)(HOST = Hostname(n)-vip)(PORT = 1521))
  )
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = pntp)
  )
  )
  

  Please mark as useful and correct issues and close the thread as answered.

  Kind regards.

• Instant tnsnames.ora for client Configuration procedure?

  The instant client has any tnsnames.ora or tnsping.exe. There is no 'normal' client available anywhere on the site of oracle, who needs this instant client which is completely unusable - http://download.oracle.com/docs/cd/B19306_01/server.102/b14196/network005.htm#CIHJHJGJ said to use Oracle Net Manager to set up the network for the instant client, but where to find the Oracle Net Manager? It is not available separately, but only with the Oracle sever Installer. Why does download the server in order to use just the customer?
  
  I created the structure of network/admin directory and copied the tnsnames.ora in it and also copied the tnsping.exe, but it does not say some 'no message file. Can someone please?

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14196/network005.htm#CIHJHJGJ said to use Oracle Net Manager to set up the network for instant customer,

  Where does say instant customer?

  and also copied the tnsping.exe Moreover,

  Copy of the files at random on installations of Oracle is obviously not possible.
  Please use an appropriate installation package. If you need administrative tools, I would say this type of installation by the full Client with the "Administrator".

  However, for normal applications need connection OIC/Net base libraries and to facilitate their deployment, Instant Client agrees very well.

• location of the file tnsnames.ora and Listener.ora

  Hello

  env: Oracle 11 g 2 - Orable Linux 6.2 64bits

  I set up a database for the client server. I installed IM and the House according to the standards of the Oracle RDBMS. Then I configured the listener to run BOF IM home. If the location of the 'ora, tnsnames' and 'listener.ora' files is $GI_HOME/network/admin.

  Customer's DBA is asking me to conform to the standard for the location of these two files. Here's what he asked for:

  / opt/oracle/owner = oracle, group = s/n (755 permissions)

  / var/opt/oracle owner = oracle, group = s/n (755 permissions)

  • -touch /var/opt/oracle/listener.ora
  • -touch /var/opt/oracle/tnsnames.ora
  • -chown oracle: dba /var/opt/oracle/listener.ora
  • -chown oracle: dba /var/opt/oracle/tnsnames.ora
  • -s /var/opt/oracle/tnsnames.ora /etc/tnsnames.ora ln
  • -s /var/opt/oracle/listener.ora /etc/listener.ora ln

  I'm completely lost here. I don't know if I'm moving these two files in the folder "/ etc", how the LISTENER know about the presence of these files in ' / etc '.

  His reason for this is to support the possibility of having several houses of Oracle's RDBMS. I don't know what he's talking about.

  Please notify.

  Best regards

  Thanks to you two!

  So basically this DBA do not like to follow standards of Oracle but his own.

  BINGO!

  What is the problem with the help of $ORACLE_HOME/network/admin for these two files if there were several homes of oracle on a server? Sorry I never got to work on a server with multiple oracle homes, so I have no idea.

  The 'standard' with several houses installation is to run the listener from the version the most recent House.  If all of the houses are of the same version (putting aside the question of 'why'), then just pick one that is going to be home for the listener.  If the installation program uses the Grid Infrastructure (ASM and/or Oracle Restart), you must run the listener from the House of IM, not House the database.

  There are some key things to consider here.

  1. the auditor is to receive and process applications for connecting customers.  This is why the listener has no meaning on the Server.  Similarly, its configuration file, listener.ora, only makes sense on the server.

  1a. a single listener, using the default name of the LISTENER and the unique default port of 1521 is quite capable of--indeed, we wanted to - several multiple databases editions of multiple service homes.

  2. the tnsnames.ora file provides a name resolution and address customers.  So it has the sense that on the client computer.

  2. when a database uses a db link to access a different database, the first database acts as a client to the second - as with any other LDAP client.

  Hi Thibaut Lacroix,.

  You have the database entry in the tnsnames.ora file? If this isn't the case, you must set.

  And then you export the sid before calling the rman target /.

  Please check and let us know the status

  Yes, we know. You said, in almost all positions, you did on this subject. We got that. Believe me, we understand that. Can we move on to solve your problem?

  Enter the user name: ops Sham $
  Enter the password:
  Connected to:

  Because, despite the "ops$"... ops$ feint isn't an authenticated OS account. This is a database of authenticated account. It's only a database of authenticated account because you gave it a password. From your previous post to Justin:

  -quote from the previous post to start-

  SQL > CREATE USER ops$ sham IDENTIFIED EXTERNALLY.
  Created by the user.
  -suspend - quote

  OK, at this point, you have an authenticated os account "$ops Sham".

  -quote to continue-
  SQL > GRANT CONNECT TO the Sham ops$;
  Grant succeeded.
  -suspend - quote

  Now, the operating system account 'sham' should be able to connect with a simple "sqlplus / '.

  -quote to continue-
  SQL > grant dba to simulacrum of ops$;
  Grant succeeded.
  -suspend - quote

  Now, anyone who uses the operating system account 'sham' can connect without a password and have all the privileges listed in the role of "dba".

  -quote to continue-
  SQL > alter the simulacrum of $ ops user identified by shamos.
  Modified user.
  -end quote-

  But now change you your account "$ops Sham" and gave it a password. OPS$ feint is therefore more than a bone authenticated account. It is now a database authenticate the account, but with a rather misleading name. At this point, if you are trying to connect as "sham of the ops$", you will need to provide a password.

  Note: most web links either saying, we can choose to connect with DB.
  I want to know the difference why this sqlplus command / error display

  Because you're tying to use authentication with an operating system account that is not an operating system os authenticated account in the database. Put "ops$" on the name of the account is NOT what makes an authenticated os account. What makes authenticated os sets the account as "identified on the outside. If you create as 'identified by somepassword', OR if you CHANGE to 'identified by somepassword' then it is NOT authenticated os.

• Creating a service; What must be included in tnsnames.ora and JDBC url?

  DB version: 11.2.0.2
  Operating system platform: Solaris 10
  
  We have a 2 RAC node.
  

  DB name   = mbsprd
  Instance1  = mbsprd1
  Instance2  = mbsprd2

  I want 1 Instance (mbsprd1) to use for our OLTP and Instance 2 (mbsprd2) application to use for another nature DSS request.
  
  According to the syntax

  srvctl add service -d <dbname> -s <ServiceName> -r <Preferred Instance> -a <Available Instance>

  I create 2 services
  
  -Creation of a service called OLTP

  srvctl add service -d mbsprd -s OLTP  -r mbsprd1 -a mbsprd2

  -Creation of a service called DSS

  srvctl add service -d mbsprd -s DSS  -r mbsprd2 -a mbsprd1

  -Start services

  srvctl start service -d mbsprd -s OLTP
  
  srvctl start service -d mbsprd -s DSS

  I guess the above steps are sufficient to set up a service on the side server.
  
  I would like to know what needs to be done on the client side.

  Can someone tell me to solve this problem in Linux? (I am new to the Linux operating system)

  Hello
  You see that your PATH variable does not contain the path to the bin of the Oracle home directory.

  Oh, after changes in the .bash_profile, you disconnected and connected again, so that changes in .bash_profile may take effect?

  Disconnect then reconnect and then check sqlplus from the terminal.

  Also if the problem persists, then paste the above values again.
