• ORA-12560 error when you try to make a data pump

  I installed oracle 11g and was trying to make a pump of the dev machine data to my computer but when I run the impdp command I get an ORA-12560: TNS:protocol adapter error.
  
  A co-worker thought that I might need to add a loopback adapter, as this had been the only thing different from his machine, where everything worked fine so I added map of closure, but this still does not work. We thought that perhaps the adapter should be set up first, I so uninstalled the database and installed again, but this also does not work, I still get the same error message.
  
  Any ideas on what I should try?
  
  Thanks for any help you can give me.

  Please post the output of the following...

  Set oracle_sid=
  
  Impdp ........
  

  I mean it please just paste in the command prompt... It is a great help

• ORA-12560 error adapter, connect to the remote database

  I started to learn Oracle for the last week or two, and certainly my installation process was a bit special. In the end, I try JBoss to connect to the database, but for now, I just want to try a simpler installation.
  
  I use Instant Client on Windows 7 with Oracle 11.2 running on a RedHat 5 virtual machine. When I connect with the following...
  
  sqlplus sys@domain:1521/sid
  
  It crashes, it's finally time. When I use...
  
  sqlplus sys as sysdba @domaine: 1521/sid
  
  It asks for my password, then gives me the error of the adapter, after I get it.
  
  My listener status is:

  My main reason to use Instant Client is simply to test the connection to the database remotely. What other information should I post? Any help would be much appreciated.

• XE on CentOS: ORA-12560 error

  I just installed XE on a CentOS 5.2 system and accesses the database by using the web page of Apex (homepage of database). I put the HTTP properties database accessible from local and remote. I am unable to connect to the database from another pc, or by using a web browser or via SQLplus and get generic error 12560 thru SqlPlus.
  
  On the PC, I put the IP address of the server in a file entry pointing to the installation of XE tnsnames it. I'm sitting next to the server and can it ping, but still cannot connect. I can post the tnsnames entry?

  You have an active firewall on the server?

• Oracle Database 11 g installation problem: ORA - 12560:TNS: Protocol adapter error.

  People,

  Hello. Initially, my Windows XP host name is 'localhost' and IP 127.0.0.1.

  I installed Oracle Database 11 g with Windows XP successfully and all customers in the database with the database instance running.

  For some reason, I uninstalled all of the database server and remove the whole installation directory /oracle.

  I have configured the address IP of Windows XP in 192.168.196.101 to ping other machines.

  For my needs, I installed Oracle Database 11 g with Windows XP again. During step 7 of 8: Oracle Database Configuration Assistant, I got this error:

  ORA - 12560:TNS: Protocol adapter error.

  I click on the button "Password management", there is no line in this window (no user name, no account of the lock).

  I have check the listener as below:

  C:\ > lsnrctl
  LSNRCTL > start
  His output: earphone HEADSET name has already been started.
  LSNRCTL > status
  Its release:... Service DB1 has 1 instance. The instance BD1 ready state. The command completed successfully.

  I check \Oracle\cfgtoollogs\dbca\DB1\trace file, the entry is:

  Listen [0] = LISTENER address = (ADDRESS = (PROTOCOL = TCP (port = 1522))(HOST=localhost))

  I also check \oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\SAMPLE\tnsnames.ora file and listener.ora file, the entries are the same as below

  HOST = localhost port = 1522

  I think that HOST = localhost and port = 1522 is the cause of the ORA-12560 error because Windows XP was configured in HOST = 192.168.196.101.

  But I do not understand how to solve this problem.

  Can any folk tell me how to solve this problem? must cancel the installation of 8 on step 7 and install it again?

  
  Thank you.

  > The problem is that I am installing Oracle Database 11 g with Windows XP

  Why? above is NOT a supported combination.

  What makes you think that it should work without error?

  Go to control panel services and are looking for what is called OracleServicexxxx. If it is not there you don't have a database.

  Jeff,

  I don't have anything with OracleServiceXXXX in my windows services.
  Why is it missing? Is this something I've done or (not) during installation?

  I guess that you have selected the option to create a database.

  I could use the database Configuration Wizard to create a database.

  This is the best option at this point.

  I have the suite starting with Oracle

  OracleOraDb11g_home1TNSListener
  OracleOraDb11g_home2TNSListener
  OracleOraDb11g_home3TNSListener
  OracleOraDb11g_home3ClrAgent
  OracleRemExecService
  OracleMTSRecoveryService
  Oracle_app_abc ~ product_112 ~ 1.0_dbhome_1ConfigurationManager

  I guess that OracleOraDb11g_home3TNSListener came with the most recent installation. How can I get rid of all previous headphones? I believe that I don't need them.

  Are still there the previous installations? You must run the net configuration assistant in each installation and remove the listener. If you can't that set them off. You can also check the SC utility that can be used to remove services.

• ORA-12560: TNS:protocol adapter error. Virtual MACHINE works on old MBP and Win7 but not on new MBP [mid 2015 retina], speed or network problem?

  We strive to use our VM on the new retina MBP (mid-2015) with MacOS X 10.11 (El Capitan) but we had a problem starting from Oracle. If we first converted our ESX VM but once on the Mac laptop Oracle (v12.1.0.1.0 on WIN2012R2) does not open the database, error;

  ORA-12560: TNS:protocol adapter error

  Does not change us any setting on the virtual machine itself so services work fine. Network has set the IP with host only. Tried with Fusion 7.1 & Fusion 8.0.2 new Mac with nothing doesn't. Also with the different versions of the VM tools. Tried to remove the NIC in Fusion and recreate, don't sucses.

  Funny enough the same virtual machine starts fine on PC (workstation 10.3.0 & Win7), MBP beginning 2011 (Fusion 7 & Mac 10.10) or ESX itself for Oracle opens the database!

  That's why we think in the direction of the new MBP specific? speed or network issue? Ring the bells?

  
  

  Help appreciated!

  Bottom line, this is a problem of Oracle who dislikes the MBP on a virtual machine.

  for reference;

  Virtual MACHINE works very well on all platforms, but not on the latest MacBook Pro (retina, 15 inch, mid-2015). So, when you try to use sqlplus you might get the error that there is no such thing as SID. Earphone works very well, but the DB process does not record with earphone or work correctly also. But the process is running and a SID tnsping returns an OK. This isn't a problem of configuration Oracle as the VM and DB works well from the moment where you run the virtual machine on a PC or an old MBP. Either way, Virtualbox has the same problem so not a problem of Fusion.

  I will record a deal with Oracle but I doubt that it is corrected.

• Error ORA-12560 on Ora11g after reboot

  Now having a major problem...
  
  I've recently set up a database under the following:
  -Oracle version: 11 GR 2 64 bit (standard)
  -OS: Windows Server 2008, running on VMWare
  -File system: ASM (thanks to grid infrastructure)
  The infrastructure of grid and Oracle itself have been installed under the same account. (It was a special local account that has been set up and account administrator privileges required).
  
  Everything is rising and running, was able to connect and everything. I made a few changes (setting mode archive log).
  
  I then did a restart of the computer.
  
  Now, whenever I try to connect as sysadmin (sqlplus "/ as sysdba") or any other user, I get the following error:
  ORA-12560: TNS protocol adapter error
  I have the problem that I try to access it locally or remotely. Manager of the company seems also not working do not.
  
  Any idea what the problem might be? I can do a TNSPing for the database, and the listener seems to be started.
  
  There were 2 small problems that I'm nut sure are related:
  -Although I installed everything under the same local administrator account (I called dbadmin), when I go in lsnrctl I can't use "reload" (gives me a "tns01190": user is not authorized to perform the requested listener command. ") but I can use if I login as "Administrator".
  -When I looked at the registry, the 'ORACLE_mydb_AUTOSTART' is set to false. There are other parts which must be autostarting, but aren't?

  Everything is rising and running, was able to connect and everything. I made a few changes (setting mode archive log).

  I then did a restart of the computer.

  Now, whenever I try to connect as sysadmin (sqlplus "/ as sysdba") or any other user, I get the following error:
  ORA-12560: TNS protocol adapter error
  I have the problem that I try to access it locally or remotely. Manager of the company seems also not working do not.

  Any idea what the problem might be? I can do a TNSPing for the database, and the listener seems to be started.

  There were 2 small problems that I'm nut sure are related:
  -Although I installed everything under the same local administrator account (I called dbadmin), when I go in lsnrctl I can't use "reload" (gives me a "tns01190": user is not authorized to perform the requested listener command. ") but I can use if I login as "Administrator".
  -When I looked at the registry, the 'ORACLE_mydb_AUTOSTART' is set to false. There are other parts which must be autostarting, but aren't?

  Under Windows, if your db service is not started, you will get the error reported.
  You can also get this error with the database service started, the database upward and operation, but your have not set ORACLE_SID in the right (or any!) value.
