RMAN connection to catalog to use FAN ?
Morning
When I look to backup a database, I use rman to connect to the target DB , and to the rman catalog
rman connect target / catalog /@rman_catalog.local
Works perfectly.
However, we patch the OS (Linux OEL7), each month.
As the RMAN Catalog is on a RAC cluster, we usually take one node down, and patch the OS (for example), and then restart the instance. Once its up and running, we take another RMAN catalog instances down, patch the OS and restart. So the database is not taken down, but the each instance is - and the OS is patched, and patched on a rolling node by node.
