Database 8i not restarting !!

[7280]

Hi,
i had shutdown one of my instances running on AIX 4.3.3 because i wanted to increase Database Buffer Cache but if i try to restart the db i get this error:

oracle_test> sqlplus internal

SQL*Plus: Release 8.1.7.0.0 - Production on Fri Sep 19 19:30:28 2003

Enter user-name:

SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus

What does it mean? I need to restart the database.

I get this error while shutdowing:
Restarting dead background process EMN0
EMN0 started with pid=13

You got TWO_TASK set? Unset it and make sure ORACLE_SID is set .

I don't had set TWO_TASK:
oracle_test> echo $TWO_TASK

oracle_test> echo $ORACLE_SID

Hi

I had the same problem with a weird process running on background,

I had to Kill the process in youre case EMNO....

 

[7280]

There's no unix EMNO process right now..

Please do you have more ideas? Still in trouble!

In fact ORA-03106 is not TWO_TASK related
Check your NLS_LANG environment variable.
