Effective in version 9.5.1, you specify the total cache size in the --cacheSize option in the InstallTests and RunTests DVOCmd commands. The PowerCenter Integration Service divides the cache size among all Aggregator, Joiner, Lookup, and Sorter transformations in the underlying PowerCenter session. The PowerCenter Integration Service allocates cache memory based on the transformation requirements, such as the number of rows processed, number of tests, and precision and scale of the table columns.
Previously, the cache size that you specified in the command option was the cache size for each transformation, except the Sorter transformation. Data Validation Option assigned 8 MB for each Sorter transformation. For example, if you set the cache size to 200 MB and the session contained two Aggregator transformations, two Joiner transformations, and one Sorter transformation, then each Aggregator and Joiner transformation received 200 MB of cache memory and the Sorter transformation received 8 MB of cache memory.
