• 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.

  Hello...
  
  I'm new to dba and I have a few questions about the ldap.ora and sqlnet.ora files... one of my friends wants to connect to a remote database (no port number)... they sent ldap.ora and sqlnet.ora files... they say that these files are to be placed under $ORACLE_HOME/network/admin... i'm a little confused here that this path is available only on the side level db...
  
  Oracle's NET8 is installed in the system... I do not know where to incorporate the files ldap.ora and sqlnet.ora allowing it to connect to this base... Please guide me on fixing this problem... Thanks in advance...

  Yes,

  You must keep the ldap.ora and sqlnet.ora under ORACLE_HOME/ntwork/admin Local computer for you is maybe praying/NET80/admin.

• Oracle files for configuration n/w. (sqlnet.ora)

  Hello all;
  
  I read the oracle documents. That is to say
  
  In the simplest form, Oracle uses three files for configuration n/w. They are
  
  Tnsnames.ora, SQLNET.ora, listener.ora
  
  When you use the remote connection, we use the listener.ora and tnsnmes.ora files.

  Oracle 10 g say differently, 11g saying differently the documents.. I know ...?

  You know, put entire sentences and paragraphs bold loose really resembling scream, many even in capital LETTERS for HELP! (see what I mean?)

  I don't know what are your specific references, when you say that the documents "tell us differently', but I think the best description/definition of"net service name"is located in the Setup Guide glossary. To quote:
  ======================================================================
  NET service name

  A simple name for a service that resolves to a connect descriptor. Users to formulate a connection request from a user name and password with a net service name in a connection string for the service to which they want to connect:

  SQL > CONNECT user_name
  Enter the password: password
  SQL > @net_service_name

  Depending on your needs, the net service names can be stored in a variety of locations, including:

  Tnsnames.ora, on each client, local configuration file

  Directory Server

  Service external naming, such as the Information Service Network (NIS) or cell Directory Service (CDS)
  ======================================================================

  The net service name is in your example of your tnsnames.ora, "ORGDB."
  The name of the service is, of course, "orcl.orgdb.com".
  'Domain name' is a standard networking term.

  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.

  SQLNET.ora is a very simple text file. I have to agree that you should be able to just build one and then distribute it.

  Maybe I didn't explain well enough.

  The problem is that the work will be done my Solaris System Admin (SA) who go out once a month. He takes with him are preparing with the difference, including work on Oracle and work when the package is installed, the work of the Oracle will be as well.

• Setting server or client SQLNET.ora

  Hello

  I do not understand if sqlnet.ora-oracle documentation. I have my perception of this file is only a client-side configuration file.

  MetaLink docID: 151972.1 describe the detection of connection dead DCD, but we're not sure if we set this client-side or server-side?

  Greetings * T

  SQLNET.ora files are optional on the client and the server. However, if you need to configure something that is only done by the sqlnet.ora, you must create the file (if it does not exist).  DCD is a device by which the * server process sends a probe packet (ping) to the customer in order to see if the client is still alive and he answers.  Thus, this configuration is performed on the server.

  (for example, another setting aside server in the sqlnet.ora is 'sqlnet.inbound_connect_timeout')

• Sqlnet.ora instance configuration when instances share the same host

  Is it possible that we keep this configuration for the instance and keep others outside this configuration?

  Altan

  Laughing out loud

  And the use of valid_node and invited_node is fairly lame to start. I always wondered why implemented oracle implementation in their layer of sqlnet at all, being the right place to do the filtering on the router ip.

  So now you must be wondering why a single instance - and no others - used it in the first place. The solution to your dilemma will depend on the answer to this question. It could be that for a particular instance of filtering IP was valid. However, the decision to do so at the level of the layer of tns was wrong, and then pass that instance to a host with other bodies which have different requirements only aggravated the original error.

• entries ADRCI SQLNET.ora

  Hi all
  
  I'm using Oracle 11 g R2. (11.2.0.3)
  
  My team application ask to add the bottom of the entries in the customer oracle sqlnet.ora file no server:
  
  DIAG_ADR_ENABLED = FALSE
  
  DIAG_DDE_ENABLED = FALSE
  
  DIAG_SIGHANDLER_ENABLED = FALSE
  
  It affects my database somehow? Disadvantages there?
  
  Kind regards

  That the definition of these parameters on fake change structure of directories of my trace files?

  No, I don't think that these false setting can change the directory structure, because the automatic diagnostic repository (ADR) is a directory structure that is stored outside the database. Setting these false stops just to create the path and save the files that are needed to send the support of Oracle. When the DIAG_ADR_ENABLED parameter is set to OFF, the tracing of the non - ADR files is used.

  See Structure, content and the location of the automatic diagnostic repository:

  Concerning the sqlnet.ora setting, it is possible to set two values as follows, but it is not always well managed
  (in a version NONE is ignored):

  SQLNET. AUTHENTICATION_SERVICES = (NONE, NTS)

  Furthermore, it affects the connections only (anyway be careful before changing this parameter).

  Thus, it is likely that the root cause of your accident.
