This video describes High Availability Large Databases (HALDBs): when you should use them, their capabilities, and other features of HALDBs.
|
|
This video continues the discussion of programming standards by coding a common copy member for all DL/I calls, using pre-coded SSAs, pre-coding a common PCB for each database, coding a common PCB…
|
|
This video describes common programming standards and best practices such as using COPY facility for COBOL and using %INCLUDE facility for PL/I.
|
|
This video describes the AIB. Using the application interface block (AIB) provides an alternate way of establishing which PCB should be used for a DL/I call. A DL/I call that uses the AIB can refer…

This video covers several more service calls that can help with exception handling, such as the ROLL call, which permits an application program to back out processing to some earlier point.
|
|
This video discusses how the INIT call is initialized. INIT call is issued implicitly by IMS by PCB at scheduling.
|
|
This video describes the INIT call. The initialize (INIT) call allows an application program to:Receive status information regarding database availability (by checking each database PCB) Inform IMS…

|
This video describes three more service calls: LOG: an explicit call interface that permits a program to write data to the log. STAT: most commonly used while developing or enhancing an IMS program…
|
|
This video describes the CHKP and XRST DL/I service calls. These service calls are frequently used together so that a failed program can be restarted and resume processing from near the point of…
|
|
This video describes the I/O PCB. The I/O PCB is a non-database PCB that is used in IMS TM systems to communicate with some device for input and output between a program and an end user of IMS in…
