Unit 3, Section 7: Documentation for screen formats and segment format reviewThis video describes the information that you need to know to format messages, such as segment formats, fill characters, logical paging, and MODname requirements. |
|
Unit 4, Section 14: Conversational programming, part 2This video concludes the discussion of conversational programming, more specifically, how to terminate a conversational transaction, processing options, and conversational programming examples. |
|
Unit 4, Section 13: Conversational programming, part 1This first video describes conversational transactions that permit IMS to retain information across multiple transaction iterations. |
|
Unit 4, Section 12: Limiting output message segments, and wait-for-input transactionsThis video describes limiting output message segments. Depending on how a transaction code is defined to IMS by IMS Systems Programmers, IMS can restrict both the size of output message segments and… |
|
Unit 4, Section 11: INQY (inquiry) callThe INQY call can only be used with an AIB. This video describes the INQY call, which can provide information about the state of resources, the execution environment, and other facts that can… |
|
Unit 4, Section 10: Application interface block (AIB)This video describes the AIB, which is an interface that provides a slightly different way for your program to issue a DL/I call. For some newer IMS calls, you can use only an AIB. |
|
Unit 4, Section 9: Exception handlingThis video describes various calls and functions that you can use for exception handling, specifically, ROLL and SET calls. |
|
Unit 4, Section 8: Initialize (INIT) callThis video describes in more detail how the INIT (initialize) call works. The INIT call can receive status regarding database availability by checking each DB PCB, and it can inform IMS that it is… |
|
Unit 4, Section 7: Managing database availabilityThis video provides an overview of how you can manage database availability by using the INIT call. |
|
Unit 4, Section 6: Log, statistics, and SNAP callsThis video describes the following service calls:LOG: This call is an explicit call interface that permits a program to write desired data to the log. STAT: This call is of primary interest to IMS… |
|
Unit 4, Section 5: Checkpoint and restartThis video describes the program flow of checkpoint (CHKP) and restart (XRST). The CHKP and XRST DL/I service calls are frequently used together so that a failed batch or BMP or JBP program can be… |
|
Unit 4, Section 4: I/O PCBThe I/O PCB is available and useful in both IMS TM and non-IMS TM environments (that is, for IMS transactions and Batch DL/I regions) that can process IMS system service calls. This video provides an… |
|
Unit 4, Section 3: GSAM considerationsGSAM is a simple IMS database access method that is available for any IMS (IMS DB, IMS TM, or IMS DB/DC) system that provides for enhanced data integrity following a program or system failure. This… |
|
Unit 4, Section 2: Batch message processing, part 2This second video on batch message processing describes the services provided by the IMS control region and converting a batch program to a BMP. |
|
Unit 4, Section 1: Batch message processing, part 1This first video describes batch message processing, BMP input, and queuing. |
