I'm trying to run the sql command line "sqlplus" on my linux machine using the command "sqlplus / as sysdba". I get the following:
SQL*Plus: Release 11.2.0.1.0 Production on Tue Sep 20 12:28:29 2016
Copyright (c) 1982, 2009, Oracle. All rights reserved.
Connected to an idle instance.
then when I write statrup command I get :
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initSID.ora'
SQL> exit
Disconnected
I looked online for a solution and I followed whats written in https://community.oracle.com/thread/2178662 enter link description here I tried the following commands before starting sqlplus again : export ORACLE_SID=SID env|grep ORA|sort which give me the following information:
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
ORACLE_HOSTNAME= HOSENAME
ORACLE_SID=SID
ORACLE_UNQNAME=DB11G
last I wrote cat /etc/oratab ,, with the following result
# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
At the end, I tried to check if my database is running using the following command ps -ef|grep pmon which showed me
oracle 18023 11347 0 12:38 pts/5 00:00:00 grep --color=auto pmon
oracle 19686 1 0 Aug23 ? 00:05:11 ora_pmon_apertureSID
So now I'm not sure whats the problem. I need to run the sqlplus Can anyone guide me
