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, ...
– OTMA CI: clients include WOLA
– IMS Connect API: clients include DataPower
– ...
– All of which support cloud technologies and enterprise mobility
IMS Version 13
4
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
– 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
5
IMS 13 OTMA Enhancements ...
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
– 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
6
IMS 13 OTMA Enhancements ...
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
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
7
IMS 13 OTMA Enhancements ...
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}
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
8
IMS 13 OTMA Enhancements ...
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
– 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
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

IMS 13 OTMA Enhancements ...
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
– 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
11
IMS 13 OTMA Enhancements ...
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
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
12
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
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
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
– 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
14
IMS 13 ISC Over TCP/IP...
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
– 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
15
IMS 13 ISC Over TCP/IP...
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
– 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
16
IMS 13 ISC Over TCP/IP...
