5.4 Create dedicated cache

Each UDV will be associated with one specific cache volume (CV) to execute the data transaction, whether it’s a global CV or a dedicated CV. Each CV can be assigned a different size. Unless specified, each UDV will use the default global cache volume. A dedicated cache volume must be created prior to setting up an UDV with the dedicated cache.

The total cache size will depend on the size of the RAM installed. By default, the total cache size is set to global cache. To create a dedicated cache volume, the desired CV size must first be determined then subtracted from the global cache. Resize the global cache by subtracting the amount needed for the CV. Finally create a new CV by setting the remainder cache to the new CV.

Figure 5.4.1

5.Fill in the desired size and click.

6.Done.

Note

The minimum global cache volume size should be no less than 40MB. The minimum dedicated cache volume size should be no less than 20MB.
