IBM is clarifying requirements that determine whether or not customers
qualify for aggregated Parallel Sysplex License Charge Pricing.
Qualifying criteria that define the "actively coupled" requirement
have been added to the Parallel Sysplex License Charge Exhibits.
Customers that do not meet the qualifying criteria will not have the
advantage of aggregating MSUs in calculating PSLC prices.
All customers that are currently receiving aggregated Parallel Sysplex
pricing, customers who have outstanding aggregated Parallel Sysplex
pricing proposals, and customers that are likely to request aggregated
Parallel Sysplex pricing soon.
This announcement does not effect PSLC charges for single systems.
IBM is clarifying requirements to qualify for aggregated Parallel
Sysplex License Charge pricing.
The clarification of the criteria is intended to provide customers
with with a more precise definition of actively coupled so they may
more easily determine when they achieve active coupling and qualify
for aggregated Parallel Sysplex License Charge pricing.
Planned Availability Date January 13, 1998
The PSLC Exhibit and the Attachment for Parallel Sysplex License
Charges require that customer's machines be operating in an "actively
coupled" environment to qualify for aggregated PSLC pricing. The
criteria clarifies what it means to meet that requirement.
To be considered "actively coupled" customers must comply with
the following conditions:
1) All Processors in the Parallel Sysplex must be physically
attached via coupling links to a common Coupling Facility
from Group B of the PSLC Exhibits and via timer links to
a common sysplex timer.
Note: If a Coupling Facility is divided into multiple logical
partitions (LPAR's), all processors must be attached to the
same Coupling Facility LPAR.
2) All OS/390 and MVS/ESA V5 images that comprise the Parallel
Sysplex environment must have at least one common systems
enablement function activated to use the coupling facility
across all images in the sysplex. Eligible Systems Enablement
functions are listed below:
-Application Data Sharing including:
-- IMS TM: with IMS DB or DB2
-- CICS: with IMS DB or DB2 or VSAM RLS
-- TSO and DB2 data sharing
-- An eligible Independent Software Vendor's Data
Base from Group C of the PSLC Exhibits.
-GRS Star Implementation
-JES2 Checkpoint in the coupling facility
-RACF database caching
-SmartBatch multisystem processing
-Automated tape sharing and switching
-VTAM Generic Resources
-VTAM MULTINODE Persistent Sessions
-System logger SYSLOG (OPERLOG)
-System logger LOGREC
-System logger Resource Recovery Services
3) The configuration and operating modes described in this exhibit
must be the normal mode of operations for this environment. The
OS/390 and MVS Image(s) participating in the above sysplex
function(s) must account for at least 50% of the total OS/390
and MVS workload on each machine.
A processor can only be in one Parallel Sysplex for pricing
purposes. If the processor is partitioned, and the partitions
are in different qualifying Parallel Sysplexes, the customer may
select which Parallel Sysplex the processor will be included in for
The customer must notify IBM when they qualify for aggregated
PSLC pricing under these criteria for current and new Parallel
Sysplexes. Sysplex pricing will apply on receipt of the
Customers currently receiving aggregated PSLC pricing who do not meet
this definition of actively coupled will be granted a grace period in
which to take action to meet the criteria prior to losing the benefit
of aggregated PSLC pricing. The grace period will vary depending on a
number of factors, among them, the number of processors and the
complexity of the sysplex function being implemented. Customers should
contact their IBM representative to determine their grace period.
Customers that do not meet the criteria at the end of the grace period
will lose the benefit of aggregated Parallel Sysplex pricing.
Effective today, customers adding or upgrading processors to existing
sysplexes for current workloads will continue to receive aggregated
PSLC Pricing during the grace period. Customers adding a processor to
existing sysplexes for new workloads must meet the criteria before this
processor's associated MSU's will qualify for aggregated PSLC pricing.
Customers installing a new Parallel Sysplex after this criteria is
announced will receive aggregated PSLC pricing when they meet this
IBM may request verification of Parallel Implementation via RMF or
The qualification criteria are effective immediately.
