RE: Converting from physical to logical standby

Steve,
For 9iR2 I attempted to extend my instatiate scripts for Physical
Standby (PSB) with Logical Standby (LSB) capabilities. It actually
worked, using vanilla hot backups.....4 out of 5 times. The quiesce
database is still needed, although it didn't take too long. So, no major
outage/standstill was needed. But, a real instantiation 'on the fly' is
not possible. AFAIK converting PSB to LSB is not possible. 

Whenever the script failed, for no obvious reason the next run went OK
most of the times. I haven't put too much effort into solving this,
because of the instability and restrictions of LSB, and lack of demand
for LSB. I'm a poor self-employed contractor ;-)

Best regards,

Carel-Jan Engel

RMAN Backup & Recovery says "RMAN backups cannot be used to create a logical
Standby database, because RMAN cannot quiesce a database".
