Hi,
We are using Networker module for Oracle. Oracle DB 11g release is
11.1.0.7. We are not using catalog database. While taking backup we
are using
4 channels and it uses 4 channels to write to single tape. For
restoration we are using 2 channels, but it is using only 1. Hence
restore is getting delayed.
What could be the reason? We are writing INDEX files also to same
tape as backup tape.
Backup scripts are given below:
Backup Software:
EMC Networker 7.5.1 Build 269
Networker Module for Oracle 4.5
Backup Hardware:
Tape Library: FibreCAT TX48 with 2 LTO4 Drives and 12 slots (1 slot
dedicated for cleaning tape).
Group details are given below:
