I don't know if this will help, but this happened to me 10 minutes ago and I did a ps -ef to see what processes I had running on my server. I then stopped all processes that were running gracefully. I continued to shutdown the database and then restarted my database. After I restarted the database, I restarted all of my processes and everything seems to be running smoothly now, and I am no longer getting that error. I have a lot of users accessing the database at all times of the day.

Check the Environment variables : ORACLE_SID ORACLE_HOME ORACLE_BASE LD_LIBRARY_PATH etc. All of these should be set in order to bring Oracle DB.

Log into sever manager or sqlplus, connect as internal and then issue the STARTUP command. You can optionally specify the STARTUP command with the PFile argument.

ORACLE_SID is suppose to be set as an environment variable. So just give type set at your shell prompt and it should tell you whether its set or not.

Hope this is of some help.

Hi,

You have not started your database before attempting to connect to it.

Follow these steps to connect to oracle (linux version)
NOTE: A SPACE IS CUMPULSORY AFTER / SYMBOL IN sqlplus / as sysdba.
To start database..

$ lsnrctl start
$ sqlplus / as sysdba
sql> startup

after this the database is initiated & started.

sql> exit

login into user like (scott or system)as

$sqlplus
username: scott
passwd:*****

sql>

steps to stop database:

exit the dbuser scott or system whatever

sql> exit

$ sqlplus / as sysdba

sql> shutdown

sql> exit

$lsnrctl stop
