IMS Version 12


Fast Path Serviceability

Solution– DEDB data sharing enhancement

• When an IMS system sends a notify message to its data sharing partner systems, new message DFS0066I is issued for each responding system

• Any partner that fails to respond causes the IMS that originally sent the notify message to issue DFS3770W

• User may need to cancel the IMS for which there is no DFS0066I message

Value– User can determine which IMS is non-responsive providing a quicker response to

a system hang

Serviceability

clients– New maximum ACEE aging value of 99,999 seconds

Value– Reduce the system storage for RACF ACEEs while providing better security and

performance– More efficient usage of storage for caching RACF ACEEs– Earlier notification of OTMA clients when IMS is terminating– Higher IMS availability for applications

IMS Version 12


Enhanced APPC/OTMA Synchronous Shared QueuesSolution

– Provide option to use MVS Cross Coupling Facility (XCF) for communication instead of RRS between Shared Queues Front-End and Back-End systems

• IMS is the sync point manager rather than RRS • AOS= parameter specifies new options to use XCF• New AOSLOG= parameter to request 6701 log record

– Remove RRS dependency for APPC’s synchronous conversation and OTMA’s Commit Mode 1 (send-then-commit) with sync level of NONE or CONFIRM

Value– Improve performance and simplify the syncpoint process by using XCF

IMS Version 12


Additional OTMA/APPC Enhancements

Solution - OTMA– Commit Mode 0 (CM0) request DFS2082

– When IMS application does not reply to the IOPCB

Value– remote application performance improvement- removes timeout wait

Solution - APPC– LU 6.2 Edit exit routine (DFSLUEE0) option

• Discard an asynchronous output message IMS cannot deliver

Value– Performance and availability improvement

24

IMS Version 12


MQ Message Expiration …

– User-Specified Expiry time (message-level)

• A value is passed to IMS if an MQ message expiry time (MQMD.Expiry) exists for the message AND the service parameter is set– Value is in 10ths of a second

– The residual expiry time for the message is built into the OTMA interface• MQ expiry time minus the time that was spent in the MQ queues

LINUX

Appl places (MQPUT)

MQIIH tran

MQMD.Expiry =100

MQMD.Expiry =60(6 sec)

IMS

OTMA: EXPRTIME usedis 6 seconds

Checked at:- Input Receipt- Msg enqueue- Appl GU

From the remote application perspective (business as usual):

- The MQPUT application will be unaware of an expiry unless it

specifies a Report option which can specify

–MQRO_EXCEPTION (Just the Expiration report)

–MQRO_EXCEPTION_WITH_DATA (First 100 bytes of the message)

–MQRO_EXCEPTION_WITH_FULL_DATA (All of the message)

IMS transaction expiration for an OTMA message Is checked in 3 phases:

- When the message is received (input receiving phase)

- When it is queued (enqueuing phase)

- When the IMS application issues GU (GU phase)

IMS Version 12


IMS 12 Systems Management

Enhancements

IMS Version 12


IMS Repository and Usage for Dynamic Resource Defin ition (DRD) Resources

Solution– Simplifies IMSplex DRD resource management– Provides a single centralized store for the DRD resource definitions

• Usage of IMS repository is optional, DRD users can continue to use Resource Definition Data Set (RDDS) instead of the repository

– Allows DRD resource definition changes to be made in repository and rolled to one or more active IMS systems

Value– Simplified management of DRD resource definitions– Eliminates the need for managing multiple Resource Definition Data Sets (RDDS) for

each IMS

IMS Version 12


Import Command Enhancement

Solution– IMPORT command may be used to update resources

• Previously, IMPORT was not allowed for existing resources– Updates required deletion then IMPORT

• IMS 12 allows IMPORT for existing resources– OPTION(UPDATE) must be included in command– Resource is updated if it already exists

Value– Usability of IMPORT and DRD is enhanced

IMS Version 12


ACB Member Online Change NAMEONLY Option

� OPTION(NAMEONLY) added for member online change

– Command processes only the named member(s) of the staging ACBLIB

– Smaller WADS

– Better use of storage system cache by WADS

IMS Version 12


Log Archiving for Non-Recoverable Databases

� Problem addressed by this enhancement

– Online backout using archived log stops when it encounters a “missing” log record

• Backout is incomplete, other database updates may not be backed out and will be stopped

– Batch backout using archived log does not backout updates to non-recoverable database but sets no flags in DBRC to prevent its use

� Control statement not to archive non-recoverable database log records

– Option applies to specified databases

� Benefit

– Eliminates potential database integrity and operational problems

SLDS CMPRSNR((dbd1,ddn1)(dbd2,ddn2),...|ALL)

SPEs: IMS 10 PM18093; IMS 11 PM19363
