(CREATION OF A HISAM OR HIDAM DBD/ PSBS
WITH PROCOPT=A AND LS)

INTRODUTION TO SSAS
(UNQUALIFIED)

IMS RETRIEVAL AND UPDATE CALLS (GHU,GHNP,ISRT,REPL,DLET) USING SSAS EFFECTIVELY (QUALIFIED & MULTIPLE CONDITIONS WITH RELATIONAL OPERATORS)
DEMO
(DB MAINTENANCE PROGRAM - ISRT/REPL/DLET)

MULTIPLE DB POSITIONING USING SSAS EFFECTIVELY (COMMAND CODES - F, L, D, P, N) ONLY HIGH LEVEL OVERVIEW (UNDERSTANDING THE CONCEPT ONLY) ON SECONDARY INDEXING, IMS LOGGING, BATCH BACKOUT, RECOVERY & RESTART)
DEMO
(USING COMMAND CODES - PATH CALL RETRIEVAL,
SETTING PARENTAGE AND USING GNP)

1. WRITING AN IMS CHECKPOINT RESTART PROGRAM
2. IMS EXERCISES (COMING UP WITH BETTER IMS
CALLS)
3. ENHANCING EXISTING PROGRAMS
4. USAGE OF GSAM
