Try to understand the bequeath process

Question

Hi,
I want to understand the bequeath process. As I know, you don't have to use listener to connect the database if you log on the server. You can use the bequeath protocol, right?
In my rac environment, I have got the following situation.
1, ps -ef | grep oracle
oracle 5695 1 0 12:55 ? 00:00:00 oraclegrieth1 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
oracle 5804 1 0 12:55 ? 00:00:00 oraclegrieth1 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
oracle 5956 1 0 12:55 ? 00:00:00 oraclegrieth1 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
2, echo $ORACLE_HOME
[oracle@css-rac1 ~]$ echo $ORACLE_SID
GRIETH1
3, lsnrctl status
Service "griethXDB.css-net" has 2 instance(s).
Instance "grieth1", status READY, has 1 handler(s) for this service...
Instance "grieth2", status READY, has 1 handler(s) for this service...
4, sqlplus /nolog
SQL> conn sys as sysdba
Enter password:
Connected to an idle instance.
SQL>
5, sqlplus /nolog
SQL> conn sys@grieth1 as sysdba
Enter password:
Connected.
SQL>
Why can I without using @grieth1 not to connect the database?

Answer 1

The SID is case sensitive in Unix.
Your SID appears to be grieth1 as opposed to GRIETH1.
Please try using grieth1 for your SID.
