GB_CACHEALLMAX is a dynamic system parameter that determines the number of blocks cached by the RMS on Alpha and Integrity servers. If a file is connected to RMS with the RMS global buffer DEFAULT option enabled, the number of of blocks cached is either a maximum of the GB_CACHEALLMAX parameter or a percentage of the file, whichever results in a larger global count.

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.
