Hot Topics:SERVICE RESTART required:
Beginning with z/VM 7.2, VMSES/E incorporates logic to identify service updates to VMSES/E "Core" components which are critical to its operation. When these updates are identified, VMSES/E issues a notification to this effect, (via message: VMF2760W SERVICE processing incomplete due to service that affects core VMSES/E parts), creates a service restart file, and cancels its operation. Service processing then must be resumed using a SERVICE RESTART command.
Service download updates:
The manner in which service content is compressed for Version 7 service orders was changed for Shopz orders as of 13 May, 2020, and for all ServiceLink (IBMLink) orders as of 12 September, 2020. All Version 7 service orders now use GIMZIP compression.
This newer form of compression — noted as v7 format by the mentioned ordering tools — is intended to be transparent with respect to how a received service package is processed, in that one continues to use the existing DETERSE command to decompress z/VM service package files.
When ordering service for z/VM levels prior to z/VM 710, be certain that v6 (TERSE) format compression is specified for your order. If a service package is ordered with v7 format, the z/VM 640 level DETERSE command will fail with a return code of 1031. In this situation, the 640 service will need to be ordered again, but in v6 format, which then should allow for successful DETERSE processing.
Note that GIMZIP compression will be used to improve service in the future, so please return to this page for updates. Also, ensure that you follow all instructions that are provided with a service order, including ignoring the GIMPAF XML and GIMPAF XSL files.
