Memory Allocation

Memory Allocation

You can set the minimum amount of cache memory that the Association transformation uses. The default setting is 400,000 bytes.
Set the value in the
Cache File Size
property on the
Advanced
tab.
The default value represents the minimum amount of memory that the transformation uses. The Association transformation tries to obtain a multiple of the default value, depending on the number of ports you associate on. The transformation uses this formula to obtain cache memory:
(Number of association ports + 1) x default cache memory
For example, if you configure seven association ports, the transformation attempts to allocate 3.2 million bytes, or 3.05 MB, to cache memory.
If you change the default setting, the transformation does not try to obtain additional memory.
If you enter a cache memory value that is lower than 65536, the Association transformation reads the value in megabytes.
