I have downloaded Oracle XE 11.2.0-1.0 and installed it on a CentOS 6.3 virtual machine with 1.5GB memory and 3GB of swap.
SYS and SYSTEM set to have password 123456. I have set
I can connect to this database with SQL Developer with the SYSTEM user. But when I want to connect with
sqlplus it says:
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
ps -fe | grep pmon shows this:
oracle 1164 1 0 11:26 ? 00:00:00 xe_pmon_XE
I have logged in as root user and I just type
sqlplus with no arguments then it asks for user name and password.
Can anyone help?
I have removed the trailing
ORACLE_HOME and it solved my problem.
