• Unable to connect to the database from Oracle Forms server

  Hello

  I installed Oracle Forms on top of Weblogic server. When I try to connect to an Oracle Forms home by TNS naming database, it returns error "ORA-12504". It works fine when I use EZConnect.

• not able to connect to the database using the oracle instant client

  Hello
  
  I am not able to connect to the database using the instant oracle from my local PC client. They use to connect to the database files and sqlnet.ora files LDAP.ora. If I want to test the connection, I found this executable tns wasn't there, so not able to tnsping. So I'm not able to solve this problem.
  
  Please let me know if a solution for everything
  
  Client Oracle: oracle 10.2bFAT client 32-bit
  
  Platform: windows 7 64-bit
  
  Thank you
  Veera

  There is little that tnsping can do sqlplus can't.

  Instead of
  tnsping mydb.myorg.com
  Try
  sqlplus-s-L /@mydb.myorg.com
  or
  sqlplus-s-L user/[email protected]

  If you get
  ORA-12154: TNS: could not resolve the connect identifier specified
  you know that the customer could not resolve 'mydb.myorg.com '.

  If you get
  ORA-12541: TNS:no listener
  then "mydb.myorg.com" could be resolved, but there is no listener it running.

  If you get
  ORA-12514: TNS:listener is not currently of service requested in connect descriptor
  then "mydb.myorg.com" could be solved, the listener is in place, and the database is out of service.

  If you get
  ORA-01017: name of user and password invalid. connection refused
  you know that 'mydb.myorg.com' has been successfully resolved, and the database is running.

  If you want more details, such as how and what "mydb.myorg.com" is resolved, turn the tracking by adding the following to "sqlnet.ora:
  TRACE_LEVEL_CLIENT = ADMIN
  TRACE_DIRECTORY_CLIENT = C:\TEMP (a writable directory)

  Then you will find lines like this in the trace file:

  -THE INFORMATION SOURCE PARAMETER FOLLOWS-
  Attempt to load system pfile source C:\oracle\network\admin\sqlnet.ora
  Source of the setting successfully loaded

  Attempt to load the local pfile source C:\Dokumente und Einstellungen\lanadvall\sqlnet.ora
  The parameter source has not been loaded.

  This shows you which configuration files are read, followed by the settings real read.

• Connect to the database using oracle forms

  Hello experts,
  
  I have installed on my computer, Oracle Developer Suite 10 g (10.1.2.0.2) (including the forms and Designer) and after that I installed Oracle Database 11 g Express Edition (11.2) Beta.
  both facilities are on the same (local) computer.
  When I chose to connect to the database, he wonder about the data connection to the database:
  username, password and database.
  I'm sure that the user name and password are correct, because I have no problem to connect directly to the database (via sql * more).
  could you please tell me what I should write in the field database? I trid XE but it dose not help.
  Can I need to make some changes manully so that it works?
  Please note that the operating system is Windows XP service pack 3.
  
  Thank you for your help.

  Dear all,

  I did the next thing through to connect to the database.
  
  (1) first of all I did called ODBC1 odbc driver

  I guess that your listener.ora always has a section of SID and you did not copy paste... Then please post the entire file

  Please open a command line window and do:
  C:\oracle\ora9I\bin\hsodbc
  After all output including the call.

  Published by: kgronau on March 6, 2012 18:31
  When the listener above is still correct, the cause would be that you have 2 SID with the same name in your listener.ora:
  SID_LIST_ODBC1 =
  (SID_LIST =
  (SID_DESC =
  (SID_NAME = ODBC1)
  (ORACLE_HOME = C:\oracle\ora9I)
  (PROGRAM = hsodbc)
  )
  (SID_DESC =
  (GLOBAL_DBNAME = ODBC1)
  (ORACLE_HOME = C:\oracle\ora9I)
  (SID_NAME = ODBC1)
  )
  )

  Please change to:
  SID_LIST_ODBC1 =
  (SID_LIST =
  (SID_DESC =
  (SID_NAME = ODBC1)
  (ORACLE_HOME = C:\oracle\ora9I)
  (PROGRAM = hsodbc)
  )
  )

  Published by: kgronau on March 6, 2012 18:34
  Once you change the listener, please stop and start the listener called odbc1: odbc1 stop lsnrctl and lsnrctl start odbc1

• slow down the connection to the database (Oracle enterprise 11g ed on RHEL 4)

  Hello
  I am facing problem when connecting to the database connection using sqlplus to my database the time consuming and it increases as the number of users connect to it increases. (although with a user of sqlplus scott/tiger@db takes 15 seconds and when simultaneously if multiple users try to connect then time required in connection is alsomost = number of user * 15 seconds.)
  
  same tnsping takes huge when 4-5 user tries to connect to the database.
  What should I do for debugging?

  Hello

  Try this:
  -Remove any nameserver entry in /etc/resolv.conf on server
  -Add name to the/etc/hosts machine like that
  127.0.0.1 localhost.localdomain localhost
  10.10.20.134 piorovm.localdomain piorovm

• Link to the database of Oracle 11 g 11.2.0.3.0 to SQLServer 2012 - 11.0.5058.0 (X 64)

  Hello.

  I want to connect from Oracle to SQL Server. I did the following steps:

  (Taking into account, that I want to connect to a database SQL SERVER called GS2PIASQL03\INSTANCE3)

  Create the odbc connection in the oracle called running GS2PIASQL03 Server

  Name: GS2PIASQL03

  Description: GS2PIASQL03

  Server: GS2PIASQL03\INSTANCE3

  With authentication sql server using a login ID and passwotrd entered by the user

  Connect to sql server to obtain default settings for the configuration option extra

  User: rema_read

  Password: xxxxxxx

  Master default database

  Use ANSI quoted identifiers

  Use nulls, padding and ANSI warnings

  Perform the conversion of character data

  Finishing and test the source data before TESTS COMPLETED successfully.

  Please I really need your help I really really need this to work and I'm completely lost know.

  Vinny.

  Hey Vinny,

  No, the host tnsnames.ora must not refer to the place where the SQL * Server database is active.  The tnsnames.ora entries is intended to guide the user who calls the database link by using this entry to a listener running on the computer and the port in the entry. The listener then directs the user to everything that is referenced by the SID in the listener. If it is an Oracle database, then you are linked to the database. If this is an entry of gateway referenced by having the (HS = OK) then you are linked to the gateway which then liaises with what non-Oracle database is accessible through the gateway of the option.  You cannot directly connect to the non-Oracle database by using the IP address of machine non-Oracle in tnsnames.ora. You need to go through the door entry referenced by the listener to establish the connection.

  For the listener, you can set the path to the ORACLE_HOME of the gateway or RDBMS. However, the best option is to give the listener a different name from the default, so for the gateway, you might have-

  SID_LIST_LISTENER_GTW =

  (SID_LIST =

  (SID_DESC =

  (SID_NAME = GS2PIASQL03)

  (ORACLE_HOME=S:\app\oracle\product\11.2.0\tg_1)

  (PROGRAM = dg4odbc)

  )

  )

  LISTENER_GTW =

  (DESCRIPTION_LIST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SLPIAM29)(PORT = 1525))

  (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1525))

  )

  )

  You can then use-

  stop LISTENER_GTW

  Start LISTENER_GTW

  Kind regards

  I have to confirm whether Oracle Business Intelligence Enterprise Edition can be supported on the basis of data Oracle 12 c.

  Thank you.

  OBIEE supports Oracle DB 12 c, you can check in the matrix of certification for details (google for the matrix).

  For a certified system, you need to upgrade from weblogic, if it's just to test or a certified system is not required you can also use it directly.

  In case your 12 c is configured as multitenant you must specify a connection to a PDB file and not the CDB (but still using a SYS / SYSDBA account) in the RCI.

• Connect to the database with SQL * more: is TNSNAMES. ORA used?

  Hello

  We have a local database called DEV01 and a copy of this database in a data center. To be able to connect to both databases, the TNSNAMES file. ORA

  on the local database server (not the one in the data center) has the following entries:

  / * Entry for the local database * /.

  DEV01_local, DEV01_local. WORLD =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = server01) (PORT = 1521))
  )
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SID = DEV01)
  )
  )

  / * Entry for the database in the data center * /.

  DEV01, DEV01. WORLD =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = server02) (PORT = 1521))
  )
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SID = DEV01)
  )
  )

  When I connect to the local database server, I set the Oracle environment as follows:

  export ORACLE_SID = DEV01

  export PATH=/opt/oracle/app/oracle/product/9.2.0/bin:$PATH

  export ORACLE_HOME=/opt/oracle/app/oracle/product/9.2.0

  Now I start SQL * more as follows:

  Oracle # > sqlplus user/user

  SQL > select instance_name, host_name from v$ instance;

  INSTANCE_NAME HOST_NAME

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

  SERVER01 DEV01

  As the SID is on two databases of the same (DEV01) I really don't understand how Oracle decides which of the SQL databases * more connects to.

  Is it the entry in the TNSNAMES file. ORA?

  But when I start SQL * more as follows:

  Oracle # > sqlplus user/user@DEV01_local

  SQL > select instance_name, host_name from v$ instance;

  INSTANCE_NAME HOST_NAME

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

  SERVER01 DEV01

  or

  Oracle # > sqlplus user/user@DEV01

  SQL > select instance_name, host_name from v$ instance;

  INSTANCE_NAME HOST_NAME

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

  DEV01 server02

  everything is as expected.

  Does anyone know who is the chosen database when just to connect with 'sqlplus user/user' (without the @DEV01 or @DEV01_local)?

  Any help will be appreciated!

  When you connect to the local database that is connected to the server01, you need only specify the sid in the environment, in this case, Oracle tnsnames file to connect, actually uses, it uses any of the listener.  It uses what is called a connection needed.  It is purely a side connection server, and as long as the sid is located in the environment resolves to a database running on that server, you will be get connected.

  When you connect using the @connect_descriptor, like you second case, then Oracle will use the configured naming, including tnsnames, methods to solve the 'real' database  In this case, the auditor is required to create the connection to the database.

• RCU error: unable to connect to the database using the contact information provided

  Hello

  I am not able to connect to the database using the remote control 11.1.1.10.1 to create patterns. I ran the UCR even a week ago and I managed to connect. My database and listener are up and running and the host and the credentials are correct. I don't know where is the problem. Any help will be appreciated. Attaching the screenshot for reference.

  Hi Handal

  Thanks for the reply. Looks like someone had blocked the firewall settings, so I was unable to connect to the database using the port.

  Thank you

• ODAC 12 c Release 3 (12.1.0.2) do support the access to the database to Oracle 10 g Release 2 or later?

  Hi ODP.NET Experts.

  ODAC 12 c Release 3 (12.1.0.2) ONLY does support the access to the database to Oracle 10 g Release 2 or later?

  
  

  It does not mean that this will not work for versions earlier before Oracle Database 10g Release 2?

  Thank you and best regards,

  Alan
