View source for GB DEFPERCENT

'''GB_DEFPERCENT''' is a dynamic [[System Parameters|system parameter]] that controls caching of files on [[Alpha]] and [[Integrity]] servers.  If a file is connected to RMS with the RMS global buffer DEFAULT option enabled, either a percentage (GB_DEFPERCENT) of the file is cached or up to [[GB_CACHEALLMAX]] blocks of it are cached, whichever results in a larger global buffer count. A percentage greater than 100 percent can be specified for GB_DEFPERCENT to provide growing room for a file in the global cache.

Note that although a maximum cache size of %x7FFFFFFF is supported for an indexed file, sequential and relative file organizations are restricted to a maximum cache size of 32767.
