Re: replication
Dear Maria, I have not heard of CDR and have not used ER. But have used HDR. This provides a hot backup type facility. Where the secondary machine is updated based on logical log buffers from the primary machine. Only the primary can be updated, but the secondary machine remains in a read-only mode. The adminsitrators guide for 7.1 (only one I have sorry) explains the HDR. Regards, Jason On 11 Aug 1997 15:23:34 -0400, m.l.wilson@larc.nasa.gov ("Maria L.
