HSMAXPGS=value

Details

The HSMAXPGS= option specifies the maximum number of hiperspace pages that can be allocated in a single SAS session for all hiperspaces. The value of the HSMAXPGS= option is equal to the product of the values of the HSLXTNTS= and HSMAXSPC= options.

The value that you specify must be in the range 0 to 2,147,483,647. If you specify 0, SAS allocates 1,920 blocks of hiperspace to the library. Check with your system administrator for any site-specific maximum number of pages you can have.

If you are responsible for controlling resource use at your site and you are concerned with hiperspace usage, you can use the IBM SMF installation exit, IEFUSI, to limit the hiperspace resources that are available to users.
