Issue/Introduction

Broadcom LDAP is being used to make changes to X(SGP) records in ACF2. These X(SGP) records use a masked SYSID of ****. Currently LDAP is only issuing commands for the current SYSID it is running on. How can other SYSIDs such as **** be specified? Can the ALTSYS parameter be used?

Resolution

The ACF2 GSO OPTS parameter ALTSYS will only be referenced when an application (for example LDAP) utilizes the Search Source Group List by SYSID Subroutine (ACF00SSY). When ALTSYS is specified, ACF2 builds source group tables for the specified SYSIDs which allows an application to access E(SGP) or X(SGP) type records for SYSIDs other than the current system. 

This is useful when using a SYSID or masked SYSID of ****  for source group records. In order for some applications to locate these records, subroutine ACF00SSY is used by the program in combination with specifying ALTSYS(****). This allows the application to access E(SGP) or X(SGP) type records that were created under a masked SYSID.

Note: Depending on the command being issued by the application, specifying ALTSYS(****) may have undesired effects. For example, issuing an F ACF2,NEWXREF,XCF(****) will cause an ACF79949 XCF SEND COMMAND INCOMPLETE message due to the fact that SYSID **** does not actually exist as a system. This message is typically preceded by a CASECCFS message that will display the active system(s) that the command was successfully sent to.
