ORA-600 that's scary stuff, As its a Oracle internal error, so always recommended to raise a ticket.
I did something else due to shortage of time:--
In my environments scenario this error came when I tried to run the database setup from data mover and it failed at
As i was under time pressure,instead of following up with Oracle I did the following steps.
As it failed while inserting into the PSDBOWNER table , there must be something fishy with the way PSDBOWNER table was created, So I created the DDL of PSDBOWNER table
SQL> select dbms_metadata.get_ddl('TABLE','PSDBOWNER','PS') from dual;
The output was :
CREATE TABLE "PS"."PSDBOWNER"
( "DBNAME" VARCHAR2(8) NOT NULL ENABLE,
"OWNERID" VARCHAR2(8) NOT NULL ENABLE
) SEGMENT CREATION DEFERRED
PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255
Then I dropped the table PSDBOWNER, and recreated the table using the above output
I reran the insert, and ORA-600 vanished.
Respond for any doubts, and keep experimenting!!
