Process network transactions without IMS DB by using IMS TM with an external database management subsystem, such as DB2 UDB for z/OS. Use DBRC to maintain system log information that might be needed to restart IMS. Run batch application programs in a TM batch region by using IMS TM to do batch processing with DB2 UDB for z/OS.

IMS-DB Tutorial. A Complete Reference for Mainframe Programmer. Get Started Audience: IMS-DB tutorial will be useful for anyone, be in a student, a software Engineer or anyone who is serious towards mastering the IMS-DB in Mainframe.

See the complete version of An Introduction to IMS. IMS DB provides access to these databases from applications running under: IMS Transaction Manager; CICS Transaction Server for OS/390® and z/OS; z/OS batch jobs; WebSphere Application Server for z/OS; DB2 UDB for z/OS stored procedures

IMS as a transaction manager can execute application programs which access IMS databases as well as DB2 tables. This session explains how the External Subsystem Attach Facility (ESAF) works and how IMS and DB2 can work together. DB2 provides database services for IMS MPP, BMP, IFP and IMS batch.

With the IMS attachment facility, Db2 provides database services for IMS dependent regions. DL/I batch support allows users to access both IMS data (DL/I) and Db2 data in the IMS batch environment, which includes: Access to Db2 and DL/I data from application programs. Coordinated recovery through a two-phase commit process.

IMS performs the actual manipulation of data in the data base. IMS consists of a set of program modules that intercepts all requests that programs make for accessing the data base. IMS uses DL/I to provide a set of programming standards for interfacing with DL/I modules.

2022年10月26日 · While IMS is still widely used in Fortune 1000 and global companies, there is a growing number of those companies that are looking to move from IMS to Db2 to use standard SQL for writing queries and maybe more importantly, tap into a deeper pool of talent to support the Db2 environment.

2012年10月6日 · DB2 is a relational structure database and IMS is a hierarchy structure database. why are you use in the developing new and existing application programming? I develop in both DB2 and IMS but lately more DB2 since Web applications can use DB2 data directly whereas in IMS you cannot (would need to possibly convert some …

2022年4月20日 · Db2 optimizes queries internally whereas IMS programmers construct access paths to data. This additional requirement will cause Db2 to consume more CPU. But, of course, that additional CPU brings with it the enormous benefit …
