Oracle Temporary Database Optimization
Zerto utilizes a temp data disk feature to optimize the replication traffic of Oracle temporary databases and it is enabled on a per-virtual disk basis. When enabled, an initial copy of the virtual disk is replicated to the recovery site, but no subsequent changes to the disk are replicated. This ensures that any application that uses the virtual disk for an Oracle temporary database sees the disk and original files in a recovery scenario without requiring any manual reconfiguration. The temp data disk feature can save over 50% of replication traffic, journal space usage, and VRA load.
Zerto best practice: Keep all Oracle temporary databases on separate virtual disks and utilize the Zerto temp data disk feature. You can test the impact of the temp data feature on bandwidth usage by editing the VPG settings to turn off the temp data feature.
