Hi there,
When a hashed file "pre-load file to memory is Enabled", a warning message as the following is showed. This hashed file is very small (only three rows in it). It doesn't need 128M cache. In another case, the problem is - Unable to allocate memory - means not enough memory for the cache. SO do we have the control of cache size?

Can the size of hashed file cache be controled?

Re: Can the size of hashed file cache be controled?
The hash file will use the minimum amount of memory necessary to cache the file. It will not EXCEED this setting. Why you get a YELLOW warning message beats me, but you did post an INFO green message.olgc wrote:When a hashed file "pre-load file to memory is Enabled", a warning message as the following is showed.

Only by limiting the data you put into the hash file to be cached. Otherwise, its a maximum cache size.olgc wrote: In another case, the problem is - Unable to allocate memory - means not enough memory for the cache. SO do we have the control of cache size?

You have global control over the hashed file cache sizes via the Administrator client's project Tunables tab. The configuration parameter DISKCACHE can also be used.
There is a separate manual on caching hashed files (dsdskche.pdf); reading this should answer all your questions.
