J just installed a new copy of Oracle Database 12c Enterprise Edition with following basic install time settings:
Skip software updates
install database software only
single instance database installation
English language
Enterprise edition
use windows built-in account
install path: C:\Oracle\
The installation went smoth without any critical warnings or errors.
After installation when I start SQL*Plus command line it requires me
User Name:
Password:
I have not specified any of these during installation. S, what could probably be the credentials?
I tried using my windows log-in user & password to login (Nte: My windows log-in name has a white space in middle as: FirstName LastName) but it issued me an ERROR message as:
Enter user-name: ******* ********
SP2-0306: Invalid option.
Usage: CONN[ECT] [{logon|/|proxy} [AS {SYSDBA|SYSOPER|SYSASM|SYSBACKUP|SYSDG|SYSKM}] [edition=value]]
where <logon> ::= <username>[/<password>][#<connect_identifier>]
<proxy> ::= <proxyuser>[<username>][/<password>][#<connect_identifier>]
Then I tried using same user name without white space but got another Error message as:
Enter user-name: ***************
Enter password:******
ERROR:
ORA-12560: TNS:protocol adapter error
Is there anywhere I am going wrong? Please suggest me the solution
Thanks...
My suggestions:
1: First ensure that you have specified ORACLE_SID AND ORACLE_HOME environment variable before trying to login. You can try following commands to set those environment variables:
Put correct path and sid_name for the following commands and insert them system environment variable. Don't forget to check the value of respective environment variable before login attempt.
ORACLE_BASE=C:\oracle;
ORACLE_HOME=$ORACLE_BASE\product\11.2\db_1;
ORACLE_SID=sid_name_here;
PATH=$PATH:ORACLE_HOME\bin;
Now, issue should get resolved if you getting trouble because of environment variable.
2: Next, verify the status of listener. See the output of following commands to confirm the status of listener:
lsnrctl status
lsnrctl services
Above command show the status of listener and associated service. If you didn't see SID and associated service name, You need to start listener service (i.e. from services.msc).
3: Sometimes, you might be getting this issue because of TNS_ADMIN not setup properly. Configure TNS_ADMIN in system environment variable and also mention in the tnsnames.ora file. Refer link for the discussion configuring TNS_ADMIN in windows environment.

I am trying to install informatica 10.4 on windows but while domain creation, it is throwing me permission issue, but i am running the installer as admin and took the command from logs which was giving issue and ran it in cmd as admin but still the same issue.
I feel installer is trying to add permissions for wrong domain / user.
How to change that to correct domain / user?

Just installed Oracle 11g XE (Windows), but can't connect in SQL Developer or run any command in CLI.
When try to connect in CLI using SYS or SYSTEM with password defined during the install, get the following error:
ORA-12638: credential retrieval failed
When I tray to connect via SQL Developer (tried via SID and Service Name, hostname=localhost, port=1521, SID=xe), get this error:
Status : Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in
connect descriptor
Already tried change SQLNET.AUTHENTICATION_SERVICES = (NTS) to (NONE) in sqlnet.ora file. When I do this, get the following error when try to connect with the SYS or SYSTEM user and password:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Already tried every solution in Google results, like reinstall, stop and start services... Mostly ask for first connect in CLI to make some changes, but even this I can't accomplish.
Any suggestions on how connect to the database?
Found the solution:
I was installing in my company Windows user domain.
First uninstall any instance of Oracle XE 11g.
Switch to a local administrator Windows user and install Oracle XE 11g.
Sign off and back to company Windows user.
Edit the file C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN\sqlnet.ora (or equivalent to your installation path). Change SQLNET.AUTHENTICATION_SERVICES = (TNS) to SQLNET.AUTHENTICATION_SERVICES = (NONE).
This change will allow you connect to database from you company Windows user.
As seen here: Error ORA-12638 in Oracle Database 11g
Try the following: Open command window, cd to Oracle bin directory, enter sqlplus /nolog. If you get a prompt enter connect / as sysdba. If you get connected then you can try "startup".

Did you try to start the Oracle RDBMS service via Services (services.msc)?
Do you use an spfile? Check the registry for ORA_SID_NAME_PFILE that is different from default location of $ORACLE_HOME/dbs. Also check the default location. Use only the default location or the registry entry removing either the registry entry or the file in the default location depending on which you want to use.
I followed the instructions mentioned to install SQL*Plus from Oracle Instant Client and How to Install SQLPlus.
SQL*Plus is successfully installed on my system but I cannot login and use it. There is a similar question here and here, but it is does not solve my problem.
On googling, most sources said that we enter a password upon installation, but I was neither prompted nor displayed any password. (I can attach terminal screen shots if it is required)
Is there any way I can login and start using SQL*Plus? Is there any default username or password?
I am stuck here: sqlplus username/password#//dbhost:1521/SID
I need a valid username and password. scott/tiger was of no help.
sqlplus / as sysdba gives this -> ERROR: ORA-12162: TNS:net service name is incorrectly specified and prompts me to enter username and password which I don't have.
I originally asked this question on AskUbuntu feeling its more appropriate there. If this question does not belong here, please comment and I will remove it.
EDIT:
I executed these statements after reading from here:
ORACLE_HOME=/u01/oracle; export ORACLE_HOME
ORACLE_SID=asdb; export ORACLE_SID
Now, On executing sqlplus / as sysdba I get the error message
ERROR: ORA-12545: Connect failed because target host or object does not exist
On executing sqlplus64 scott/tiger#//dbhost:1521/SID I get the error message
ERROR: ORA-12154: TNS:could not resolve the connect identifier specified
It does not have anything to do with Ubuntu. When you enter sqlplus / as sysdba sqlplus tries to connect to the local database, which sid and oracle home should be specified by the environment variables ORACLE_SID and ORACLE_HOME. You, obviously, have not defined these variables.
All you need is to get the username, password, host name, where your database is located, port for the listener (the default port is 1521) and the Oracle SID. Then connect with sqlplus username/password#//dbhost:1521/SID. If you know the password for SYS user and have orapwSID file in the $ORACLE_HOME/dbs directory on the server side, you can connect with sys with the following command: sqlplus sys/password#//dbhost:1521/SID as sysdba.
moving everything into instant_client_11_* directory worked for me.
When I run the NetCA silently on Windows Server 2012 R2, it prompts me to specify a password "Oracle Home User Password". Is there some way that I could provide the password as a parameter or in the response file. I do not see any default property in the netca.rsp but was wondering how to make it completely unattended.
FYI, the output when I run the netca in silent mode. See the last line in the output where it prompts me to specify the password. Also, I am running the command prompt as administrator and I have even tried to login as 'oracle' user account to run the netca, but I run into the same prompt.
C:\oracle\product\12.1\dbhome_1\BIN>netca -silent -responsefile "C:\Oracle DB Server and Client\installer\netca.rsp"
Wed May 13 10:42:44 EDT 2015 Oracle Net Configuration Assistant
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = C:\Oracle DB Server and Client\installer\netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Enter Oracle Home User Password:
I was able to resolve the issue by providing the password in the response file.
#SERVICEUSERPASSWORD;String;Windows service user password
# If the oracle home is installed as secure user, supply the password
SERVICEUSERPASSWORD=""<password>""
Its a bit confusing when it prompts for "Oracle Home User Password" while the property in the response file reads SERVICEUSERPASSWORD.
I'm trying to connect to from SQL*Plus and get error ORA-12154, but I can connect from SQL Developer without any error. I can tnsping and also lsnrctl is okay and the listener is up and running.
I can connect as sys like sqlplus sys as sysdba which works fine; but with another user I do sqlplus username and when I type the password it gives me:
ORA-12154: TNS:could not resolve the connect identifier specified
SQL*Plus interprets an # symbol as the start of a TNS alias. If your password has that in it then it will be interpreted that way even if you are not trying to connect over SQL*Net, but with a local connection. So if you do:
sqlplus user/p#ssword
... then it will take just the p as the password, and the #ssword as the alias, so it will try to find a TNS alias of ssword in your tnsnames.ora file. Since that doesn't exist, you'll get the "ORA-12154: TNS:could not resolve the connect identifier specified" error.
That applies when you put your password in at the prompt too, so if you do:
sqlplus user
Enter password: p#ssword
you'll get the same thing. You can connect by enclosing the password in double-quotes:
sqlplus user
Enter password: "p#ssword"
but you can't do that with the unprompted version.
You're probably better off changing your password to something without that particular character if you want to be able to connect from SQL*Plus as well as from other clients that don't interpret TNS in the same way.
SQL Developer, for example, accepts the password and connection settings as separate fields; it isn't trying to parse the string you entered to identify its components, so it doesn't get confused. Even if you tell SQL Developer to connect using a TNS alias, it will use the tnsnames.ora value you select from its drop-down list, it won't try to take it from the user or password fields.
This one worked for me ( and was easier to implement from my behalf )
From : TNSPING OK but sqlplus gives ORA-12154?
Create an environment variable TNS_ADMIN that points to the directory where your tnsnames.ora file resides. Then try to connect with sqlplus.
TNS_ADMIN = D:\oracle\12.1.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora
If that works, then my guess is you maybe installed the Oracle client software too, and when you run sqlplus, it looks for the tnsnames.ora file in your client home.
-- Instructions for Adding the Environment variable TNS_ADMIN in windows
Go to control panel / system
select Advanced system settings
Select "Advanced" tab, and the environment variable button is at the bottom.
create new variable TNS_ADMIN and give the path where the .ora files are stored. e.g. C:\app\oracle\product\11.2.0\client_1\network\admin
