The next step
For all DBAs, systems programmers and technical support personnel the logical follow-on to this is the five-day IMS/DB & IMS/TM for Technical Support course.
- Headphones with a microphone.
- Sufficient bandwidth, at least 1.5 Mb/s in each direction.
On successful completion of this course you will be able to:
- Describe the architecture of IMS batch and online systems
- Analyze database and communication calls
- Identify appropriate logical and physical database design features
- Describe the structure of secondary indexes and logical relationships
- Use IMS utilities to backup, restore, and reorganize the database
- Discuss the facilities available in IMS to provide data integrity and system availability.
- Trace the flow of a transaction through an IMS system
Who Should Attend?
All those working in IMS Applications and Database Development, or any systems and operations personnel who require an understanding of the IMS environment.
A general understanding of the IBM enterprise server (mainframe) computing environment and an appreciation of application development concepts is assumed.
