How SIDR and SIDL values for remote trans and descriptors are stored

For the resource definitions that have different attributes among IMS systems (such as the SIDR and SIDL values for each MSC-capable system), the stored resource definitions in the repository consist of a generic section (for the common attributes) and an IMS-specific section (for the attributes that are different for each IMS system).

For remote transactions and transaction descriptors, the SIDR and SIDL values are not the same. The SIDR and SIDL values for each IMS system are maintained in the repository in an IMS-specific section. Each IMS has its own specific section for the SIDR and SIDL values. For local transactions and transaction descriptors, the SIDR and SIDL values are set to 0 in the repository in the generic section. When the stored resource definition is imported from the repository either during AUTOIMPORT processing or during processing of the IMPORT command, the SIDR and SIDL values are set to the lowest local SID value of the IMS system where the runtime resource definition is created.

The SIDR and SIDL values in the repository for remote transactions and transaction descriptors remain in the IMS-specific section and are not updated or collapsed into the generic section when the EXPORT command with the SET(IMSID(*)) keyword is issued. To modify the SIDR and SIDL values for remote transactions and transaction descriptors, you must issue the EXPORT command with a specific IMS ID specified on the SET(IMSID) keyword or the default SET(IMSID()) keyword to route the command to the IMS whose definitions are to be exported.
