    LEVEL ID CHECKPS
    Shows how often, in checkpoints, the level ID of a page set or partition is updated. When zero (0), down-level detection is disabled. When five (5), down-level is enabled.
    Use the following criteria to decide on a suitable value for this parameter:

    • How often are backup and restore methods used outside of the DB2 control (such as DSN1COPY or DFDSS dump and restore)? If rarely used, there is no need to update the level ID frequently.
    • How many page sets are open for update at the same time? If DB2 updates level IDs frequently, there is extra protection against down-level page sets. However, a performance degradation can occur if the level IDs for many page sets must be set at every checkpoint.
    • How often does the subsystem take checkpoints? If the DB2 subsystem takes frequent system checkpoints, set the level ID frequency to a higher value.

ACTIVATE I/O SCHEDULING
Determines whether the I/O scheduling feature is activated. DB2 parameter SPRMIOP in DSN6SPRM .
Field Name: QWP4IOP

VALUE FOR TRIGGER DRAIN
The percentage below 100% DSMAX that open data sets can reach before an asynchronous drain is started. The default is 1, meaning that asynchronous drain starts when the number of open data sets reaches 99% of DSMAX.
DB2 defers closing and deallocating the table spaces or indexes until the number of open data sets reaches one of the following limits:
  • The MVS limit for the number of concurrently open data sets.
  • 99% (default) of the value that you specified for DSMAX.
When one of these limits is reached, DB2 closes a number of data sets not in use equal to 3% (default) of the value DSMAX. Thus, DSMAX controls not only the limit of open data sets, but also the number of data sets that are closed when that limit is reached.
DB2 parameter SPRMTDD in DSN6SPRM.
Field Name: QWP4TDDN

MAX NUMBER OF DDS WITH HOLD

DETAILED MEASURED UNIT PRICE TRACKING
Specifies whether DB2® performs detailed tracking for measured usage pricing. You can select the following values:
YES
DB2 does detailed measured usage tracking if SMF type 89 records are activated. When SMF89 is set to YES, DB2 invokes a z/OS® service on every entry into or exit out of DB2 to ensure accurate tracking.
NO (the default value)
DB2 does not do detailed measured usage tracking. If the SMF type 89 record is activated, only high-level tracking is recorded in the SMF type 89 record. Selecting NO reduces CPU usage, but also increases the amount of time spent in DB2 as measured by SMF 89.
Note: Select SMF89 YES only if you use measured usage pricing.

  • When PREPARE or EXECUTE IMMEDIATE is performed
  • When REMOTE BIND of a package is performed.
ZPARM name DRDA_RESOLVE_ALIAS in DSN6SPRM.
Field Name: QWP4RSLV

PC YES SPECIFIED
Shows whether the IRLM uses the cross-address-space program call. This parameter determines where the IRLM lock control block structure is stored.
If you run a tightly-controlled environment and virtual storage is not constrained, use PC=NO. PC=YES is the conservative choice where insufficient information about the environment is available to make a well-informed decision.
With PC=NO, locks are managed in extended common service area (ECSA) and it is possible to achieve better CPU performance, because DB2 does not use cross-memory services for IRLM requests. However, ECSA is a limited resource and constrains the size of the private address space area available above the 16-MB line. The demand for ECSA storage to support locks may be excessive when one or more of the following conditions are true:
  • Extensive use of row-level locking
  • Ineffective lock avoidance
  • Infrequent application commits
  • Lock escalation via NUMLKTS and LOCKMAX is disabled because the applications cannot tolerate the impact
  • Effectively no limit on the number of locks taken by an application (NUMLKUS is set very high)
  • Multiple DB2 subsystems with IRLM PC=NO reside on the same z/OS image
Assuming the average lock consumes 536 bytes of storage, a single application which takes 100000 locks before a commit would consume almost 52 MB of ECSA when IRLM is configured with PC=NO. MAXCSA would have to be set to at least 52 MB. If a very large number of locks are held by concurrent application processes, the demand for ECSA may not be able to be supported.
Recommendation: If you run applications that have many of the above characteristics, it is strongly recommended to use PC=YES. Certain ERP vendor applications that run concurrent processes can acquire a very large number of held locks that would require a very large setting for MAXCSA, or cause an ECSA overflow which would adversely impact the availability of the z/OS image.
If PC=NO is selected, MAXCSA should be sized to support the concurrent number of held locks required and to avoid an ECSA overflow condition. When setting MAXCSA, check to ensure that the ECSA setting in PARMLIB is sufficient to support the aggregate demand from IRLM and other subsystems. The ECSA size for z/OS is specified by the CSA keyword in the IEASSYSnn member in SYS1.PARMLIB.
With PC=YES, locks are managed in the extended private area of the IRLM address space. This can increase the CPU cost of lock and unlock requests relative to PC=NO. However, with reasonable lock avoidance, the total CPU overhead is likely to be limited to 1 to 2%, which is well within measurement noise and therefore not significant.
With PC=YES, the MAXIMUM ECSA option is ignored but must not be zero. The amount of storage allowed for LOCK usage is determined from the extended storage provided to the IRLM address space at startup time. This amount is reduced by 200 MB to allow a buffer for IRLM and z/OS required storage and for DMBS MUST COMPLETE processes. The amount being monitored can be seen in the display message from the irlmproc,STATUS,STOR command. IRLM still uses CSA and ECSA for other purposes. If you need to create a dump for DB2 diagnostic purposes, you need to ensure that IRLM is included in the dump, and that the dump data sets are large enough to hold IRLM.
PC=NO is a good solution when one or more of the following conditions are true, particularly when running a data sharing configuration:
  • Optimal CPU performance is required
  • No constraint is necessary on available ECSA
  • Significant IRLM lock contention and a very large number of lock requests with ineffective lock avoidance
  • Relatively high IRLM SRB time
YES puts the lock control block structure in the IRLM private address space, and the program call instruction is used to address it. IRLM still uses CSA and ECSA for other purposes. With PC=YES, the MAXIMUM ECSA option is ignored.
Field Name: QWP5PCY

BLOCK OPT 1 ROW SORT (OPT1ROWBLOCKSORT)
YES indicates that sort access paths are disabled (if possible) if OPTIMIZE for 1 row with a query is used. If a possible access path avoids a SORT, DB2 chooses this access path.
ZPARM name is OPT1ROWBLOCKSORT in DSN6SPRM.
Field Name: QWP4O1RBS
