Example 2 - Making services available to all address spaces z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |
|
This example shows how a service provider makes services available to all users. The example uses the same storage areas as Example 1 (see Table 1 for the storage areas used), however, it does not need the AX list. The main difference between Example 1 and Example 2 is Example 2's use of a system LX and an AX value of 1. A system LX allows the service provider to connect an entry table to all address spaces, and the AX gives the service provider PT and SSAR authority to all address spaces. Note: Do not use a system LX unless your service is intended for all
address spaces. Establishing a system LX makes the ASID of the address
space unusable until the next IPL. For more information about ASID
reuse, see Reusing ASIDs.
