Oracle Database Discussions

dear all.

Facts:
Oracle Std edition 10g r2 10.2.0.1
RHEL AS linux version 4.

I connect through dblink from db1 to db2 in order to insert select millions of rows. Suddenly, the session shows me the next errors:


ERROR at line 1:
ORA-02068: following severe error from DB_PLELDS (this is my dblink)
ORA-01089: immediate shutdown in progress - no operations are permitted

My alert log shows :

i think that this error is about queue, but in note 1014091.102 (metalink) doesn´t explain well. I have to add more job_queue_processes?

thanks a lot for your help.
