Move Cache Directory

You can move the default cache directory from the Oracle MaxRep Replication Engine to the Oracle FS System.

Prerequisites

An Oracle FS System LUN that is configured with the Oracle MaxRep Home storage profile.
Note: Create the LUN on the an Oracle FS System that is on the same SAN fabric as the Replication Engine.
The new LUN is mapped to the Replication Engine. Use the Map LUN action from the Toolkit for MaxRep of the Oracle MaxRep GUI.

At the time of installation, the home LUN is configured on the Replication Engine. The home LUN is the cache directory for the web server, configuration files, and replication data and as a result, can be IOP intensive. If your system configuration is very large or you need faster drive access to cache your data or web server, you can move the home LUN to the Oracle FS System. There are several factors that can affect home LUN performance such as the amount of replicated pairs and their associated change rates.

As a general guideline, when the number of replicated pairs for a home LUN reaches 50, Oracle recommends moving the home LUN to external storage. When you create the new LUN use the Storage Profile, Oracle MaxRep Home.

Log in to the Support User Interface page on the control service Replication Engine.
Result:
The Dashboard page displays.
