Presentation Information

Author: Nick Cosenza Company: iWay Software Presentation Title: Got Mainframe? What’s New for the Mainframe? Presentation Abstract: Join us for this presentation and see what iWay Software

has been up to on the mainframe! Learn what’s new with iWay’s Data server and CICS and IMS transaction system access and other important new capabilities. iWay Software, in its endeavor to be the world's largest integration software provider, has developed new and improved mainframe technologies. This session, which will include a live demonstration, may prove to be the one-stop shop for customers interested in unlocking information held within their mainframe transactional-based systems. The discussion will delve into the adapter offerings within the iWay Universal Adapter framework and the adapters offered within the iWay Server 7.x product line.


Got Mainframe? Agenda

Mainframe Data Adapter Updates

(The iWay Data Server)Mainframe Java Adapter Updates

(The iWay Adapter Factory) iWay Service Manager (iSM)Demonstration


Mainframe Data Adapter Updates


Got Mainframe? Adabas/DB

Connection Pooling support Last opened databases will be closed when

agent is disconnected or closed MU/PE derived sub/super descriptors Support for field’s SQL options


Got Mainframe? Adabas/DB

Postponed Database closing Databases participating in the request remain

opened until it changes one of the followingDatabaseFileDatabase open modeAccess mode (read/write)


Got Mainframe? Adabas/Natural

Two ways to access natural programs Invoke natural from CICS

Uses CICS Adapter to call natural CICS configurations required Transactional in nature

Natural batch adapter Runs natural batch programs No changes to the natural program


Got Mainframe? DB2

DB2 DB2 UNICODE Support Multiple Language Support BLOB data type for Update/Insert DB2 Nickname support


Got Mainframe? IMS/DB

IMS/DB Automatic IMS region reconnect feature

New parameter IMSRECOM in the IMS special service definition block

Time interval in min between attempts to re-connect to IMS region via DBCTL

Inserting data into non-keyed segmentHandle data insert into the non- keyed

segments Create synonym for logical DB


Got Mainframe? IMS/TM Via the iWay Data Server

Usability Table file IMS Select from IMS transaction WebFOCUS


Got Mainframe? CICS Via the iWay Data Server

Usability Table file CICS Select from CICS program WebFOCUS Compatibility with older CICS solutions


Got Mainframe? VSAM

RRDS support in VSAM Adapter Stage 1: Supported Stage 2: Adapter can utilize user provided

hash routine to generate RRN value for READ/WRITE operations

VSAM files under CICS control Read/write support Dirty reads avoided


Got Mainframe? Datacom/DB

Access File Attributes TRACE={ YES | NO | CBS } (file level) (YES is

obsolete, supported for compatibility) SEQACCESS={ YES | NO } (file level) FOUNDLIMIT=nnnnnn (segment and file level) REJECTLIMIT=nnnnnn (segment and file level) KEYNAME=eeeee (segment level) FIELD=<fieldname>, SIGN=<sign>, TYPE=C


Got Mainframe? Datacom/DB

New adapter enhancements Adapter is reentrant Only elements that contain active fields are

requested from Datacom Any field defined in the master file may be used for

joining Read in physical sequence by commands

GSETP/GETPS is used if parameter KEYNAME has no value for the Root segment and sequential access is chosen

Connection or URT Create synonym from Web console


Got Mainframe? IDMS/SQL

New adapter enhancementsForeign key support

Multi-segment master files Create synonym from Web console


Got Mainframe? LDAP Via the iWay Data Server

New Adapter for LDAP CR SYN and TABLE support for stored procedures

Using DBMS temporary files as HOLD Samedb feature


Got Mainframe? samedb

Example TABLE FILE STXT31T

SUM F02CHAR10 BY F01INTON TABLE HOLD AS TEMP FORMAT SAMEDB PERSISTENCE

GLOBAL_TEMPORARY IF READLIMIT EQ 10 END SELECT T1."F01INT", MAX(T1."F02CHAR_10") FROM TTXT31T T1

WHERE ROWNUM <= 10 GROUP BY T1."F01INT"; CREATE GLOBAL TEMPORARY TABLE TEMP ("F01INT" INTEGER NOT NULL , "F02CHAR10" CHAR(10) ,PRIMARY KEY("F01INT") ) ; INSERT INTO TEMP SELECT T1."F01INT", MAX(T1."F02CHAR10") FROM TTXT31T T1 WHERE ROWNUM <= 10 GROUP BY T1."F01INT";


Got Mainframe? JDBC Via the iWay Data Server

JDBC – Certified list on adapter tree


Got Mainframe? iWay Data Server Update and More Info

Unified server

Clear diagnostics for ALL Adapters

Migration path for all SSCTL server customers

Tony Hurrell Presentation:


Mainframe Java Adapter Updates


Got Mainframe? Mainframe Java Adapter Updates

Current IMS and CICS Java Adapters:

Local Transaction SupportCICS via extended call IMS/TM via IMS ConnectLUW extendedApplication control via process flow



Future IMS and CICS Java Adapters:

Global transaction supportCoordinator is J2ee application serverAdapter is resource manager iWay “remote APPC” on mainframe Two phase commitRecoveryMigration path for BEA/JAM customers



Mainframe Events for CICS

Current TCPIP sockets Byte string to XML using Cobol

Future EXEC CICS LINK program name CICS program name is remote system Program name could be iSM!


Mainframe Java Adapter Updates iWay Service Manager (iSM)


Got Mainframe? iWay Service Manager (iSM)

New iWay tooling iWay Service Designer Workbench

iWay process flow Application explorer

Mainframe connections Web Services

Demo: Integration example for CICS IMS/TM RDBMS: iWay adapter that accesses all your

database adapters
