Socket Connections
In a managed environment, all socket connections between IMS TMRA and IMS Connect are persistent:
Reusable connections available from connection pools
Connection is disconnected when
Error occurred (except execution timeout), or,
Cleaned up by connection manager based on connection pool properties Two types of persistent socket connections
Shareable persistent (recommended)– IMS TM Resource Adapter generates clientID
Dedicated persistent *– Client application provides socket identifier using IMSInteractionSpec property clientID
In a non-managed environment, connections are disconnected after each interaction There is no pooling of connection
Connection cannot be reused
*Dedicated Connections will be stabilized and no new enhancements. Recommend to use Sharable connections

Transactionality
Capability that allows IMS transactions to participate as a resource in two-phase commit external transactions Requires a syncpoint coordinator
RRS on z/OS and/or an external coordinator, e.g.,IBM WAS (Websphere Application Server)
Requires client code that uses IMS TMRA
Local Environment WAS, IMS Connect, IMS, and RRS must be in the same
z/OS image **
Distributed environment (Global XA transaction) IMS Connect, RRS and IMS must all exist in the same z/OS image *
Remote environments use XA
IMS Connect
Acts as an extension to RRS and is the SDRM (Server Distributed Syncpoint Manager)
Assists RRS in communicating with other syncpoint coordinators
Acts as the CRM (Communications Resource Manager)

IMS OTMA Hold Queues
An OTMA Client can request, at Client Bid time, that OTMA allows each TPIPE to have a “special” queue, normally referred to as a Hold Queue
Requested by IMS Connect
Hold Queues are for Commit Mode 0 only Used when a message can not be immediately delivered
A message on a hold queue will only be sent by IMS when explicitly requested with a RESUME TPIPE from the client
Hold Queue is used in following cases OTMA client (or its remote client) returns a negative acknowledgement to IMS
Input to OTMA specifies “Send Only”, but IMS application creates a reply
An IMS application creates a message - other than the reply message itself - for an OTMA destination using an Alternate PCB
The name that identifies a Hold Queue has two components The OTMA Client name
A Remote Client ID which equals the TPIPE name
In other words, each OTMA Client has its own Hold Queues in IMS
To retrieve a message on a hold queue, the remote client must issue the RESUME TPIPE request through the OTMA client to which it is queued

Asynchronous Output – Super Member A super member is a special OTMA member to keep the IMS Connect
asynchronous messages for a set of IMS Connects SMEMBER= on the HWS statement
Benefit IMS asynchronous output messages are sharable for a set of IMS Connects.
The end users are not aware of this feature.
Ensures asynchronous output messages available to any instance of IMS Connect running in a Parallel Sysplex environment

Asynchronous Messages – Purge or Reroute
Asynchronous messages appears on a hold queue when Undelivered commit mode 0 output messages (e.g. during timeout or secondary
outputs)
Secondary output from program-to-program switch (primary interaction can be Commit Mode 1 or Commit Mode 0)
Application inserts to ALT PCB
Handling Purge
The output is discarded from the current queue (OTMA TPIPE)This is the default option
Reroute
The output is moved from the current queue to a user specified destinationCan be retrieved asynchronously
Retrieving Two modes: Single no wait, single wait

Asynchronous Messages – Purge or Reroute …
New options supported on shareable persistent socket connections only
PurgeAsyncOutput
IMSInteractionSpec property: purgeAsyncOutput
TRUE (default) means purge undeliverable CommitMode 0 output
FALSE means queue undeliverable CommitMode 0 output to:– “reRoute” Tpipe if specified, or
– Tpipe with name of shareable persistent socket connection
reRoute
Used only when purgeAsyncOutput is FALSE
IMSInteractionSpec properties: reRoute and reRouteName
TRUE causes undelivered Commit Mode 0 output to be queued to Tpipe whose name matches specified reRouteName
FALSE (default) causes undelivered Commit Mode 0 output to be queued to Tpipe whose name matches generated clientID of shareable persistent socket connection

Asynchronous Messages – Retrieve
Use Interaction Verb SYNC_RECEIVE_ASYNCOUTPUT_xx
Two modes
SINGLE
Retrieves one message per interaction if a message available at the time of the request
SINGLE_WAIT
Retrieves one message per interaction
Will wait for a specified time for message to appear on the hold queue
Specify hold queue name
using the Client ID property with dedicated connection
using the Alternate Client ID (reRoute Name) property with sharable connections
32 © 2007 IBM Corporation
IBM Software Group
Asynchronous Messages – Alternate Client ID Support
When WAS application issues a RESUME TPIPE, it can use a shareable socket and specify an Alternate Client ID
Enables application to use a shareable socket to retrieve asynchronous output messages that are queued to any specified clientID undelivered CM0 output
ALTPCB output messages
Simplifies writing of server application (“listener”) that retrieves messages for one or more hold queues
With this support, it is now possible to use shareable sockets in every case, and so avoid problems associated with Sysplex Distributor
IMS V10 adds new security check for RESUME TPIPE Check the userid associated with input message is authorised to access specified
TPIPE (alternate client ID)
33 © 2007 IBM Corporation
IBM Software Group
Asynchronous Messages – Alternate Client ID Support …
In this example, a SEND_ONLY transaction is used to create a message on a hold queue, which is then retrieved by exploiting the alternate clientID support
CM0 and Shareable sockets used in both cases

IMS V10 Callout Support
Asynchronous outbound support from IMS applications using ALTPCB
1. Asynchronous Callout to EJB Customer provides “listener code” in JCA EJB application
2. Asynchronous Callout to Message Driven Bean (MDB) Use JCA 1.5 inbound architecture support – MDB acts as listener, and
calls appropriate service or routine
End-to-end tooling available
3. Outbound Web Services support in IMS SOAP Gateway IMS SOAP Gateway acts as listener and calls Web Service
WDz tooling used to read WebService Description and generate IMS message definition and XML transformation routine
In each case, a reply from the called service will be processed by a new IMS transaction

Final Thoughts
Service Oriented Architecture has revolutionized the way business is done
Standard interfaces and qualities of service inherent in SOA have made integration of IT assets and heterogeneous systems a reality
IMS is well positioned as a major player in this space with a variety of technologies that project IMS assets into the SOA foundation model
