I have recently started working with Oracle 8.0.5. The task I
am trying to achieve is to copy a large number of rows from one table
to another to speed up a query. The number of rows is around the
200,000 figure from a table of about 1 million. The problem I am
getting is that when I run my query (which annoyingly worked first
time) I get this error:
ORA-01555: snapshot too old: rollback segment number 9 with name "RG3"
too small
I have tried to adjust the rollback setings with the Oracle Storage
manager, but whenever I set a new rollback segment to Online I then
cannot access it any longer and get the error..
ERROR initializing rollback ORA-00942 table or view does not exist.
If I right click on a rollback segment it crashes the client!
I have tried increasing the size of the RBS table to 100 Meg but still
get this error (it was initially set to about 10K!! (would I need to
add a new rollback segment for it to use this new space that I have
added?
Also is there a way of turning off the rollback, so data is writen
directly to the db without going through the rollback ??
Please help.. this is driving me nuts..
Thanx in advance
Graeme
