Oracle 7 -> 8 Migration Issues

Oracle 7 -> 8 Migration Issues

Oracle 7 -> 8 Migration Issues

(OP)
What issues have people come across when migrating ftom Oracle 7 to 8?

I'm considering recommending the upgrade and I'd like to get some feel (from an independant source that's not trying to sell me consulancy) for the scal of the project.

Regards

RE: Oracle 7 -> 8 Migration Issues

Well itsa really very troublesome and ireally do mean so.
We've just migrated from 7.3.2 to 8.0.3 and it stinks there are problems of all nature including even the pmon gewts stuck considering many issues i'm even planning to downgrade to 7.3.4

RE: Oracle 7 -> 8 Migration Issues

My experience has been good, as long as the target version of Oracle is 8.0.4.2 or above. 8.0.3 has too many problems, and while 8.0.4.0.0 fixed most of them, it introduced two known problems (with RMAN and Parallel Server) that weren't fixed until 8.0.4.2.

8.0.5 is best; very much bug-free, near as I can tell, plus some new stuff for Enterprise Manager, so use 8.0.5 if you can.

By way of a tip, be aware that the "7->8 Migration" utility, although it comes on the Oracle8 CDROM, this component must be installed under the existing Oracle7 "$ORACLE_HOME", not the new Oracle8. The "mig80" program itself must be linked with Oracle7 and run as an Oracle7 program. Sort of counter-intuitive...
