submitting JCL jobs, transforming the result

into the right format…

Not as error prone as before

Completely new requirements due to increased complexity

So far, views did not play an important role in the SAP context no monitoring available

For CDS views are essential

crucial to have a possibility to monitor CDS statements, which means the views / functions,

especially with regards to their dependencies

So far, static SQL was not common in the SAP context no monitoring available

With ZDO it changed (~thousands of procedures & triggers for ZDO)

Two detail views to provide information about them, their create statements, and their dependencies…

With CDS it changed (new need to monitor the CDS functions)

DB2 12 Enablement


Requirements for DBA Cockpit with DB2 12

Minimum Requirements for

Toleration of DB2 12:

SAP Support Package Requirements have

been aligned to the DB2 11 Requirements –

if your system is ready for DB2 11, it works

with DB2 12 as well

SAPCL 721 Patch Level 11 or higher

Recommended Requirements to be met in

order to provide Full Support for DB2 12:

See SAP Note 2302525 - DB2-z/OS:v12:CCMS:

DBA Cockpit with DB2 12

Provides an overview about the changed areas

Lists the ABAP support package levels for SAP

and SAPCL


DB2 12 Readiness Check

Run Report DB2_V12_CHECK in order to check if

prerequesites are met.

Also available as correction instruction

See SAP Note 2355075


Installation Parameters with DB2 12

Installation Parameters has been enabled for DB2 12

New SAP Note 2239553

has been made available


Statement Cache Enhancements


New Wait time counters for

L-locks and P-locks are helpful for

monitoring the workload on DB2

Data Sharing

Avg wait time for pipe wait

(INSERTS) concerns the monitoring

of new SQL INSERT algorithm in

DB2 12

Avg wait time for parallel queries

to sync parent/child tasks

provides better monitoring for query

parallelism

This is helpful for CDS


New TS Type PBR RPN & Lift Partition Limits (1)

New TS Type PBR RPN now supported

In that context – DSSIZE on partition level



New TS Type PBR RPN & Lift Partition Limits (2)

Dependent on a new TS type

adjusted limit calculations within

DB02 KPIs

TS Limits

Partition Limits

Index Limits

In correlation to new TS type

support of extended RID


Virtual and Real Storage

IFCID 225 was

enriched with some

new counters within

the DB2 12. The

following metrics

appear on the Virtual

and Real Storage

monitor:

Real storage in use

for 64-bit (KB) (2G

frames) for DBM1 and

DIST


EXPLAIN Table Changes

So far: Explain Table Maintenance performed directly by DBA Cockpit

Table layout etc. delivered via SAP SPs

Check and adaption done automatically

Now: Explain Table maintenance performed via Stored Procedure ADMIN_EXPLAIN_MAINT

DBA Cockpit now simply calls ADMIN_EXPLAIN_MAINT (effective for DB2 11 as well)


Benefits:

Explain table layout always current (independent of SAP maintenance level)

Robust against DB2 intra-release changes


Planning Calendar (DB 13) and Space Monitor (DB02)

Enabled DB12 features within Planning Calendar:

New keyword for RUNSTATS: Invalidatecache YES/ NO (SAP Note 2261867)

New mapping table format for REORG (SAP Note 2251508 )

Automated RUNSTATS PROFILE via SYSSTATFEEDBACK (SAP Note 2306718)

Stored procedure DSANCCOX was enriched with new result set fields (SAP Note 2345842)

Enabled DB12 features within the Space Monitor:

Lift partition limits for UTS PBR RPN (SAP Note 2265560)

New limit calculations (SAP Note 2284249)
