I have installed the OracleXE112_Win32 on windows. When i was connecting to DB getting following error.
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory
Process ID: 0
Session ID: 0 Serial number: 0
And i was given the startup commnad in the command prompt it was giving "Insufficient privileges".
To fix the issue can i run the following commands.
# su - oracle
$ source /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh
$ sqlplus / as sysdba
Still i have not used the SQL developer, using the SQl Run command.
Please help on this.
