OTMA Enhancements

� OTMA (Open Transaction Manager Access) value proposition

– Strengthens IMS as a foundation for open integration technologies

• Used by:

– IMS Connect: clients include IMS TM resource adapter and WAS,

WMB, WESB; DataPower; IMS Soap Gateway, ...

– IMS MQ Bridge: clients include WMB, RYO, ...

3

– IMS MQ Bridge: clients include WMB, RYO, ...

– OTMA CI: clients include WOLA

– IMS Connect API: clients include WebSphere Smash

– ...

– All of which support cloud technologies and enterprise mobility

IMS Version 13

IMS 13 OTMA Enhancements ...

� OTMA early termination notification

– Autonomic enhancement for higher availability that allows OTMA clients to be informed of an IMS shutdown earlier in the termination process

• Potentially reduces unsuccessful attempts to send in new transaction

messages that cannot be processed

– Can expedite shutdown processing

4

– Can expedite shutdown processing

– Planned outages (e.g., /CHE FREEZE | DUMPQ | PURGE)

• Sends resource monitor protocol message during Phase 1 of IMS shutdown

– Unplanned outages (e.g. abend)

• OTMA issues XCF IXCLEAVE immediately after the log buffers are purged

• Function being added to IMS 12: APAR PM73869

IMS Version 13


� A new global flood control option that enforces the global flood limit

– Rejects new transaction input and protects IMS from storage exhaustion

• Versus just a warning message

– Note: Individual Member level flood control is unchanged

• Warning at 80%, Rejection at 100%, Relief at 50%

• Enabled by

5

• Enabled by

– Issuing “/DIS TMEMBER ALL INPUT xxx” command

• Previous releases caused only a warning

– Specifying INPT value in a special new member client descriptor

• Reserved name of DFSOTMA

IMS Version 13


� A special new client descriptor (optional)

– Using existing ‘M’ descriptor type in DFSYDTx member of IMS.PROCLIB.

M client-name keywords

Where:

client-name is DFSOTMA

6

client-name is DFSOTMA

keywords are: INPT= <VALID> global flood control limit DRU= <Ignored>T/O= <Ignored>MAXTP= <VALID> global max number of tpipes that can be created

M DFSOTMA INPT=22222

– New system client name for all the OTMA members, DFSOTMA, is introduced to set global values

For example:

IMS Version 13


� Enhancements to OTMA destination descriptors

• Simplify asynchronous messaging to WMQ

• Remove the need to code the DFSYPRX0/DFSYDRU0 exits

• Provide dynamic change capability with the Type-2 commands

– New descriptor TYPE={MQSERIES}

7

– New descriptor TYPE={MQSERIES}

• Provides asynchronous callout and messaging support (ISRT ALTPCB)

– Specification of EXIT={YES | NO}

• Determines whether or not the OTMA exits are to be called

– Corresponding enhancement to IMS Type-2 OTMADESC commands

• [CREATE | UPDATE | DELETE |QUERY] OTMADESC

– Recoverable across warm and emergency restarts

IMS Version 13


� New mechanism to differentiate between CM0 versus CM1 output message counts for HOLDq-capable clients

– Can help analyze potential bottlenecks

– Enhancement to /DISPLAY TMEMBER TPIPE command and output

• Provides separate counts for the two output queues

HOLDq is a TPIPE secondary queue used

for three types of messages:

• ALTPCB messages chained to the

first control block used for IOPCB output

• Send-only messages

• Rejected IOPCB output

8

– PRIMARY versus HOLDq

• Applicable only to HOLDq-capable clients, e.g. IMS Connect

– Output messages retrieved using Resume TPIPE protocol

• Only affects non-shared queue systems

– New OUTPUT display parameter is mutually exclusive with SYNC and QCNT

parameters

IMS Version 13


� Concerted effort to reduce MIPS in IMS 13 includes OTMA

– More efficient hashing technique for control blocks

• IMPACT to an environment depends on volume of activity

• Example:

– Every CM1 (Send-then-commit) transaction request has a control block

associated with the port TPIPE during processing

10

associated with the port TPIPE during processing

• If a slowdown in IMS or zOS occurs or if the system is actively

processing large numbers of requests then an increasing number of

these blocks remain active

• The improved hashing technique results in a more timely and efficient

search for a specific block during application GU or checkpoint

– Usage of the CPOOL and DFSBCB in XCF Message Exit instead of

the STORAGE OBTAIN macro

– Removal of unnecessary MVCL hot spot

IMS Version 13


� Enhancement to ICAL synchronous callout request

– Addresses partial response message due to inadequate application specification

• Provides the ability to complete the retrieval of a reply message

– Without having to re-issue a complete ICAL “SENDRECV” and associated

network transmission costs

11

network transmission costs

– New “RECEIVE” subfunction code

• With an expanded response area

– Retrieves the response message after an ICAL “SENDRECV” is issued with an

inadequate response area specification and gets partial data (AIB RC X’100’, AIB

RS X’00C’)

• IMS 13 keeps a copy of the entire response message in the control region

private storage

– Until a subsequent ICAL “SENDRECV”, syncpoint, or application

termination

IMS Version 13

IMS 13 ISC Over TCP/IP

� ISC Over TCP/IP value proposition

– New option that supports TCP/IP network connectivity for Intersystem Communication (ISC) connections

• IMS – CICS

– CICS 5.1 is requires

12

– Provides a strategic protocol alternative to SNA/VTAM

• Allows an all inclusive TCP/IP solution for networks

– Supports a communication capability with CICS that is in-line with evolving

technologies

IMS Version 13

IMS 13 ISC Over TCP/IP...

� Highlights

– Supports both static and dynamic terminals

• Static terminal definitions

– SYSGEN stage 1 TYPE, TERMINAL, SUBPOOL macros

– DFSDCxxx PROCLIB member

• Dynamic terminal specification

13

• Dynamic terminal specification

– Logon descriptors in the DFSDSCMx or DFSDSCTy PROCLIB member

– Leverages IMS Connect

• Enhancements to the HWSCFGxx configuration member

– No IMS Connect user message exit changes

– Uses CSL to communicate between IMS and IMS Connect

• Requires Structured Call Interface (SCI) and

Operation Manager (OM)

IMS Version 13


� Functionality

– CICS IPIC (IP Interconnectivity) provides START / RETRIEVE(asynchronous processing) support

• When CICS is a front-end system:

– IMS response mode transactions are not supported

14

– IMS response mode transactions are not supported

– IMS conversational transactions are not supported

– CICS application program cannot use SEND/RECEIVE

• When IMS is a front-end system:

– Transaction support is the same for both ISC VTAM and ISC TCP/IP

– Transaction flow is always asynchronous

• No change to existing programs on either side of the

connection

IMS Version 13


� IMS terminal definitions

– Static terminals:

• TYPE, TERMINAL, VTAMPOOL and SUBPOOL macros in Stage 1 gen

– Continue to be required for static ISC terminals (VTAM or TCP/IP)

• New keyword: ISCTCPIP in DFSDCxxx

– Specifies that an ISC terminal is to use the TCP/IP support

15

– Specifies that an ISC terminal is to use the TCP/IP support

– Addition, modification, deletion of the ISCTCPIP parameter requires a cold start

• If ISCTCPIP is changed and IMS crashes, ERE ignores the change

– Dynamic terminals (ETO):

• New Logon descriptor information

– UNITYPE=ISCTCPIP, LCLICON=name of local IMS Connect

• User descriptors are optional

– Default user descriptor of DFSUSER will be used

IMS Version 13


� The Common Service Layer (CSL) provides the Structured Call Interface (SCI) for communications

– Each IMS and its local ISC-routing IMS Connect system must be part of the same IMSplex

– IMS Connect’s HWSCFGxx configuration member

• New CICSPORT parameter in TCPIP statement

• New ISC statement

• New RMTCICS statement

16

• New RMTCICS statement

• The Operations Manager (OM) provides type-2 cmd support

– Across an MSC link

– And synchronously receive the response back during the same UOW

– Where IMS internally schedules the transaction initiated by the ICAL call as an

OTMA transaction

• Uses a new type of OTMA destination descriptor (TYPE=IMSTRAN) which has been

introduced specifically for synchronous program switch support

– And the target transaction can be

• An IFP, MPP, MD BMP, or JMP in IMS TM or TM/DB environments

MPP4

IMS Version 13


� Uses OTMA Destination Routing Descriptors

– Which externalize the routing definitions and specifications for callout

messages and synchronous program switch messages

• Allowing up to 510 destination routing descriptor entries defined in

DFSYDTx member of IMS.PROCLIB

– With new TYPE= IMSTRAN for synchronous program switches

21

– With new TYPE= IMSTRAN for synchronous program switches

D entry_name keywords Where entry_name is descriptor entry name and can be masked by ending in an *

keywords are: TYPE=IMSTRANLTERMOVR=name
