IMS 12: Simplifying

Connectivity


IMS to IMS TCP/IP Communications

Solution

– Provide communications between IMS systems using TCP/IP via two IMS Connect instances

Value – Enhances connectivity – Supports TCPIP communications to invoke transactions

between IMS systems without having to create or maintain a separate gateway solution

– Reduces the maintenance cost by eliminating the need to maintain a RYO IMS Connect gateway application solution

Multiple Systems Coupling (MSC) TCP/IP Link

Solution

– Support for MSC communications across a TCP/IP network • New physical link type MSPLINK TYPE = TCPIP

– MSC communicates with IMS Connect within a IMSPlex to

send/receive messages via the TCP/IP network • IMS Connect manages the TCP/IP communications

• MSC manages the message processing

• Structured Call Interface (SCI) used for communication

Value

Open Transaction Manager Access (OTMA) TCP/IP

Connection Enhancement

Solution

– OTMA can now send transaction messages from applications running a

dependent region across a one-way TCP/IP connection to another IMS

system for processing • Using SEND_ONLY protocol

• A remote IOPCB reply would go on remote HOLD queue (TPIPE = OTMxxxxx) and

require a RESUME_TPIPE

– OTMA destination descriptor has new parameters specified when a

remote IMS is the TCP/IP destination for transaction messages

Value

– Enhances connectivity

– Removes need for an intermediate gateway between IMSs

– Simplifies definition of remote IMS system as TCP/IP destination for

OTMA transaction messages

including: Alias, Client, Converter, Datastore, IMSPlex, Link, MSC,

ODBM, Port, Racfuid, RmtIMSCon, SendClnt, UOR

Value

– Efficiency by using single type-2 command to receive output that

requires several current IMS Connect commands

– Improve ease-of-use for managing IMS Connect resources, by

enhancing type-2 command architecture to include IMS Connect

resources

Shared Queues

Solution

– New capability removes the dependency on RRS in a

Shared Queues environment for • APPC synchronous conversations and OTMA CM1 (send-then-

commit) interactions Applies only to synclvl=None | Confirm

o Synclvl=Syncpt still requires RRS

• IMS is the sync point manager rather than RRS

– Shared Queues Front-End and Back-End systems use

XCF for communication

Value

– Improve performance and simplify the Syncpoint

process

Simplify


Enhanced OTMA Security

Solution

– New capability creates, shares and caches a single ACEE

associated with a RACF userid • Shared across multiple OTMA member clients (TMEMBER)

– 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

– Higher IMS availability for applications

Scalability


Additional OTMA/APPC enhancements

Solution

– New OTMA option for the input commit-then-send message to

request an IMS DFS2082 message when IMS transaction doesn‟t

send back an IOPCB to ease CM1 to CM0 application conversion,

reduce unnecessary timeout in remote application

– New APPC return code on DFSLUEE0 user exit to inform IMS to

discard asynchronous output message if cannot deliver, rather

than put back on the queue. Value

– Improving performance

– Enhancing availability

Scalability

Availability


IMS TM Resource Adapter Enhancements

Solution
