  I just installed Oracle on mu Ubuntu 12.4 following the instructions here:

  and here:

  However, when I try to log on to the database, I created during installation using sqlplus, it hangs for a minute or two until it-error:

• managing the Oracle ERROR ORA-12170: TNS: Connect timeout occurred

  Hello all dear
  
  We have a server that is responsible for collecting data from some customers. In each of these devices, we have installed Oracle 11.2 g and that they are connected via DB-link. There is a stored procedure that test the connection before doing this either by running the command (+ select count (*) of dual@db_link1+). In the situations that one of the clients is not accessible, this ORA-12170 error occurred and there will be an end to MS. Now, I want to avoid this and want to sp jump this client and connect to another. I wonder if there is an exception that is raised by this fatal error and we can do it.
  
  Thank you

  Thank you

  You know what is the exception: it is 12170. So can you not name and use it in a normal EXCEPTION clause? http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/errors.htm#sthref889

• ORA-12537

  Hi friends,
  
  I have a 3rd party application that runs on Oracle 10 g DB (Aix 5 L). It worked properly for 1 month now.
  
  But suddenly today it struck this ORA-12537?
  
  Which of the following statements is close to this scenario? or do you have other ideas?
  

  What to do with ORA-12537: TNS: connection closed error
  The ORA-12537 is an information message and means that the connection has been closed. This can be caused by a number of reasons:
  1. Database is shut down (maybe for nightly backup), but connection to database was kept by client.
  2. A time-out occurred on the client-connection.
  3. When firewall closes idle connections.
  3. A configuration problem in sqlnet.ora or listener.ora.
  4. You have a path name that is too long for the Oracle TNS client on windows. (MetaLink Note:263489.1 )
  This issue is due to the connection string being large enough that the connection packet is being split into two packets and then sent to the listener. There are several workarounds for the issue.
  a. Install the exe in a shorter named directory.
  b. Modify the TNS Names entry so that it is shorter.
  c. Replace domain names with IP Addresses if that shortens and vice versa.
  d. Remove any parameters from the entry that are not needed.
  e. Patch the Database Listener to the most recent version.
  5. Oracle security is enables (for example in Oracle Apps). Solution either:
  a) Edit sqlnet.ora file and add your client-ip to tcp.invited_nodes.
  b) Remove secutity by editing sqlnet.ora and comment out parameter tcp.validnode_checking = yes by adding # at the beginning of the line.

  What do you mean by #1 "kept silent"?
  
  All this will fail on the first day of release, but its been running for 1 month now :(

  There are several reasons that occur this error. One of these processes to achieve (sessions), first check that. So now again once you get this error then connect as sysdba and:

  sqlplus "/as sysdba"
  
  select count(*) from v$session;
  
  show parameter processes;
  
  show parameter sessions;
  

  If reached setting process you increase this setting in the form:

  alter system set processes= scope=spfile;

  When everything has failed, read the Fine Documentation

  http://www.Oracle.com/technetwork/database/features/OCI/IC-FAQ-094177.html

  "How can I specify the connection in Instant Client mode strings?
  All methods NET naming Oracle does not require the use of ORACLE_HOME or TNS_ADMIN (to locate the configuration such as tnsnames.ora or sqlnet.ora files) work in Instant Client mode. In particular, the connection string can be specified in the following formats:

  A SQL Connect URL string in the form:

  Host: [port] [service name]

  such as:

  dBase-Server - 5:4321 / ORDERS

  As a pair of keyword / value Oracle Net. For example:

  "(DESCRIPTION = (ADDRESS = (PROTOCOL = tcp) (HOST = dlsun242)
  (PORT = 5521))
  (CONNECT_DATA = (SERVICE_NAME = bjava21))) »

  Naming methods that require TNS_ADMIN locate configuration files continue to work if the value of the TNS_ADMIN environment variable.

  If the TNS_ADMIN environment variable is not defined and TNSNAMES entries for example, inst1, are used, the variable ORACLE_HOME must be set, and the configuration files are supposed to be located in the directory of $ORACLE_HOME/network/admin.

  Please note that the ORACLE_HOME variable in this case is only used to locate the Oracle Net configuration files, and any other component of Client Code Library (OCI, NLS and so forth) don't use the value of ORACLE_HOME.

  The adapter unreserved or empty connection strings are not supported. However, another way to use the empty connection string must affect on UNIX TWO_TASK environment variable, or the LOCAL Windows variable, a tnsnames.ora entry or a pair of keyword / value Oracle Net. If LOCAL or TWO_TASK is set to a tnsnames.ora entry, then the tnsnames.ora file must be loaded by setting ORACLE_HOME or TNS_ADMIN.

  Thanks in advance.

  I've learned to trust in your obfuscation you covered something important, or you are showing some apples and oranges.  Error to declare you come from not being able to find referenced in tnsnames.ora entry, but the way you say you created your link db, you hardcoded the entire connection, so he never users tnsnames.ora.

  I would change the definition of db_link

  create the database link * _DBLINK

  connect to the USER IDENTIFIED BY 'user '.

  using "REM."

  Then create an entry in your tnsnames.ora

  REM =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = *. *. *. *)(PORT = 1521))

  )

  (CONNECT_DATA = (SERVICE_NAME = REM)

  )

  )

  Also, use server name instead of the HOST = IP address

  The closer looks that you can miss brackets final closing on your original definition.

• ORA-12518: TNS:listener could not hand off client connection

  Hello

  I'm getting "ORA-12518: TNS:listener could not hand off client connection" error trying to connect to the "PDB". Here are the details of my env and I do:

  Windows 7

  My PC to install Oracle 11 g 2 Client (that's how I got this PC). And I already 11 GR 2 installed Oracle software and a local database that is named "ORCL" (whichdesignates currently the stop).

  Yesterday, I installed Oracle 12 c (12.1.0) and created ORCL12C (CBD) and a PDBORCL (PDB). I connected to the PDBORCL as SYS and created user 'SCOTT '.

  I am able to connect to ORCL12C (PEH) without any problem (SQL * more and TOAD). I can go to PDBORCL (alter session set container = pdborcl) without problem. But I get the error above (ora-12518 am) when I try to connect to the user 'SCOTT' created in 'PDBORCL' using SQL * more or TOAD. I want to connect to the user SCOTT and create objects in schema SCOTT, etc.. I get the same error, even if I try to connect to the PDB as user SYS (alter session command works fine).

  I am new to 12 C. So it is quite possible that I'm doing something fundamentally wrong.

  Hello

  I think you are the problem of configuring the following listener results:

  >

  1. (SID_DESC =
  2. (GLOBAL_DBNAME = PDBORCL)
  3. (SID_NAME = PDBORCL)
  4. (ORACLE_HOME = u01/app/oracle/product/12.1.0/dbhome_1)
  5. )
  6. )

  >

  as you can see, you have defined an entry static listener for SID PDBORCL. If I read your message correctly, you are CDB Instance SID is ORCL12C and you're PDB is PDBORCL.

  So, in my opinion, as part of the configuration is the problem. PDB is saved as a dynamic Service to the Instance that you added

  an entry static listener for a non-existent Instance. And so you're static listener overlaying the APB Service dynamic PDBORCL configuration.

  and that is why it does not work.

  Look at the output of a registerd APB to a listener success:

  lsnrctl status

  ...

  Summary of services...

  Service '+ ASM' a 1 instance (s).

  Instance '+ ASM' READY State, has 1 operation for this service...

  Service 'ORCL12C' has 2 occurrences.

  Instance of 'ORCL12C', status UNKNOWN, has 1 operation for this service...

  'ORCL12C' instance, State LOAN, has 1 operation for this service...

  Service 'PDBORCL' has 1 instance (s).

  'ORCL12C' instance, State LOAN, has 1 operation for this service...

  The command completed successfully

  ..

  Hi EdStevens,

  I used option TNS with Alias network as 'OCA010' in Sql Developer.

  I checked in tnsping and tnsnames.ora directory is correct.

  Please find below the exit of tnsping:

  Have you worked from the link I provided?  (I don't think you have time to do).

  It is possible that your tnsnames.ora is corrupted by some weird characters printable somewhere.  In some versions of the oracle, he might be sensitive to spaces vs. tabs.  If in doubt, netca to add entries, rather than doing it by hand.

• ORA-12505, TNS: Listener does not currently of SID in the connection descriptor (code: 2 011)

  I get this error when you try to create a data store for Oracle database of the Disqualification.

  ORA-12505, TNS: Listener does not currently of SID in the connection descriptor (code: 2 011)

  I am able to connect to this database by using the same credentials through SQL, but the Disqualification, I'm not. Do I need to do anything in linux server before the implementation of Oracle data warehouses?

  Thank you

  Ravi

  There are a number of ways.

  1 use a JNDI connection configured in WebLogic and select by name

  2. use the LDAP connection or TNS - see http://docs.oracle.com/middleware/1213/edq/DQEXT/config_dbase.htm#DQEXT202

  3. Add an oracle.xml file in [local disqualification home] / dbconnectors with the following content. This will allow you to select the service name in the standard Oracle data store wizard:

  Class = "com.datanomic.utils.databasespecies.species.Oracle"

  MaxNameLength = "30" invalidnamechars ="" ' >

  %Species.Oracle

  {JDBC:Oracle:Thin:@${service = "srv"? /': "} ${host}: ${port} {service ="srv"? '/' : ':'}${sid}

  Oracle

  {JDBC:Oracle:Thin:@${service = "srv"? /': "} ${host}: ${port} {service ="srv"? '/' : ':'}${sid}

  ${superior (schema = "? user: schema)}

  dbproductname ~ = '(?i) oracle'

  name ~ = ' $BIN\\ [A-Za-z0-9 + /] {22, 24} ==------$\\p {digit} +'

  user = ${user}

  password = ${password}

• ORA-12154: TNS: could not resolve the connect identifier specified

  Hello

  I installed Oracle 11 g server in Windows 2008 and also installed customer DB 64 & 32 on the same server client.

  When I try to test the Oracle DB connection using the UDL file, I get the error message below. Please could you help me solve this problem.

  -Microsoft Data Link Error.

  Test connection failed because of an error initializing provider.

  [DBNETLIB] [ConnectionOpen(connect()) (Connect()).]

  SQL Server is not, or access is denied.

  --------------------------- OK  ---------------------------

  I have connected to SQL using sysdba and tried to connect to the schema. It is not connection and throwing below error.

  "ORA-12154: TNS: could not resolve the connect identifier specified.

  I checked the TNSNAMES.ora file. Everything seems fine.

  Thank you

  Hello

  I see just a glance on the tnsnames file you are missing at least one sign =...

  You have

  ORCL

  (DESC...

  You should have

  ORCL =

  (DESC...

  There may be other issues too, but give that a try at first - you better run netmgr to allow oracle to create the file for you.

  See you soon,.
