IMS Application Modernization - IMS UG May 2012 Stockholm, Helsinki

  1. 1. Kyle CharletSTSM, IMS SOA and Modernizationcharletk@us.ibm.comIMS Application Modernization © 2012 IBM Corporation
  2. 2. AgendaIMS modernization overview IMS database solutions IMS transaction management solutions DataPower and IMS connectivity IMS TM application development IMS TM connectivity2 © 2012 IBM Corporation
  3. 3. IMS Modernization Solutions IMS access anywhere IMS TM and DB Resource Standards-based data server and TM Adapters Open systems access Web services Web 2.0 (Mashup Center) WebSphere TM/DB access Universal JDBC Java API driver T IMS C P Java Universal DLI / C API driver Catalog I TM Access DB access P RYO z/OS DataPower IMS SOAP Gateway TM access3 © 2012 IBM Corporation
  4. 4. IMS Open Database Solution statement Extend the reach of IMS data – Offer scalable, distributed, and high-speed local access to IMS database resources Value Business growth – Allow more flexibility in accessing IMS data to meet growth challenges Market positioning – Allow IMS databases to be processed as a standards-based data server Key differentiators Standards-based approach (Java Connector Architecture, JDBC, SQL, DRDA) Solution packaged with IMS Enables new application design frameworks and patterns JCA 1.5 (Java EE) JDBC4 © 2012 IBM Corporation
  5. 5. IMS Open Database JavaEE JDBC Universal drivers DLI Direct IMS JavaEE Universal DRDA over TCP/IP z/OS JDBC DRDA over TCP/IP drivers DLI DRDA over TCP/IP Open Systems (e.g.; LUW) IMS z/OS5 © 2012 IBM Corporation
  6. 6. Solution highlights – JEE deploymentUniversal DB resource adapter JCA 1.5 – XA transaction support • Manage multiple datasource connections in a single UOW – Local transaction support • Manage multiple datasource connections each in their own UOW – Connection pooling • Pool released connections for future use – Connection sharing – Multiple programming models available • JDBC (Universal JDBC driver incorporated) • CCI with SQL interactions • CCI with DLI interactions6 © 2012 IBM Corporation
  7. 7. Solution highlights – JDBCUniversal JDBC driver Significant enhancements to classic JDBC offered in IMS 9 and IMS 10 – Standardized SQL support – XA transaction support (type 4) – Local transaction support (type 4) – Concurrency control • Control release of distributed locks – Updatable result set support – Batching support • Fetch multiple rows in a single network call – JDBC metadata discovery supportStandard SQL and metadata discovery enables significant integration opportunities for IMS7 © 2012 IBM Corporation
  8. 8. Solution highlights – DLIUniversal DLI driver – Java implementation of DL/I API – Complete DL/I support for database access – All IMS command codes supported – Can mix usage of JDBC and DLI drivers in the same application • SQL cannot always express what DLI offers8 © 2012 IBM Corporation
  9. 9. Open Database and the Universal driversDeep synergy with the IMS catalog – Direct access to IMS metadata in the catalog – Virtual and cloud deployment capabilities • No longer file-system dependent for metadata – Industry-leading data type support • Complex and flexible – Mapping supportDeep synergy with Java z/OS and z196 – Significant performance improvements – Continued partnership with Java z/OS labContinued SQL standardization and support – Including similar connection parameters as DB2 for commonality across IBM drivers – More to comeContinued integration across the IBM portfolio9 © 2012 IBM Corporation
  10. 10. Data typesData types have multiple metadata elements – Application data type • Universal drivers use application data type to present data to clients – Physical data type • Universal drivers use physical data type to marshal/unmarshal data to and from the database – Example • Application data type is DECIMAL(10,2) [decimal with precision 10 and scale 2] • Physical data type is a signed packed decimal (AD community doesn’t need to know this)New data type support – Structs (nested n levels with no constraint on element data types) • Accessed via SQL and DLI – Arrays (nested n levels with no constraint on element data types) • Accessed via SQL and DLI – User-defined • Name of UDT can be defined to the catalog and intended to be used at runtime by Universal drivers to marshal/unmarshal data • Can be part of a Struct or Array element10 © 2012 IBM Corporation
  11. 11. MapsMapping support – A Map is metadata that describes how a field (or set of fields) are mapped for a particular segment instance – Metadata captures the various cases and for each case defines the set of fields to be used for that case – Maps can be defined to the catalog – Example •Insurance segment mapped multiple ways depending on value of a ‘Policy Type’ field Policy Type Property Type Rooms Value Address Make Model Year Value Color M - - - - Ford Escort 1989 2K Red 555 Disk Drive H Single Family 5 500K - - - - - Way, 9514111 © 2012 IBM Corporation
  12. 12. Additional enhancements SQL – FETCH FIRST <n> ROWS ONLY – INNER JOIN <table2> ON <table1.col1> = <table2.col2> Connection properties – currentSchema – maxRows – fetchSize – Tracing • traceFile, traceFileAppend, traceDirectory, traceLevel Variable length segment support – VL segments contain a two byte length (LL) field that will identify the size of the segment instance – Universal Drivers are now sensitive to the LL field of a VL segment and will manage the IO area of the segment instance on all CRUD calls12 © 2012 IBM Corporation

  15. 15. IMS 12 catalog Trusted IMS metadata information Comprehensive view of IMS database metadata (including application metadata) managed by IMS with standard access patterns (JDBC/SQL) Offers metadata discovery and exchange via IMS Open Database and the IMS Explorer for Application Development Scalable Open Database solution – large scale deployment into virtualized production and test environments Enables broad IMS integration into the IBM and non-IBM portfolio of tools (Optim Development Studio, Rational Asset Analyzer, InfoSphere Data Architect, etc) PSB PSBGEN source PSBLIB ACBLIB IMS ACBGEN IMS Explorer DBD DBDGEN source DBDLIB Catalog15 © 2012 IBM Corporation
  16. 16. IMS catalog – intended support PSB PSBLIB source DDL IMS Explorer Catalog ACBLIB DBD DBDLIB source IMS • IMS DB changes start with catalog • IMS loads resource information from catalog • ACBLIB/PSBLIB/DBDLIB updates will be the by-product of catalog updates • Tools that use these libraries can continue to operate, but should migrate to catalog • PSB and DBD source can still be optionally generated from PSBLIB and DBDLIB16 © 2012 IBM Corporation
  17. 17. Dynamic database - Data Definition Language SQL incorporates DDL to modify the schema of a database Authoring DDL is straight-forward with sophisticated tooling support in the industry SQL/DDL can be used to update/add metadata in the catalog without the need of a GEN – Directly update the catalog IMS can be notified of such an update and load the new definitions It is our intention to offer this type of dynamic definition for IMS17 © 2012 IBM Corporation
