The course contains 6 units:
Unit 1: A single ECB running on one I-streamThis unit describes how the z/TPF system manages a single ECB running on a system with one I-stream.
Unit 2: A single ECB running on one I-stream with VFAVirtual file access (VFA) is a memory cache that the z/TPF system uses to cache database records in local memory. By keeping copies of records in VFA, ECBs can access database records from local memory much faster than reading the records from DASD. This unit describes how the z/TPF system manages a single ECB that runs on a system with one I-stream with VFA.
Unit 3: Multiple ECBs running on one I-streamThis unit describes how the z/TPF system manages multiple ECBs that run on a system with one I-stream.
Unit 4: Record locking and serializationThis unit describes how the z/TPF system manages record locking and serialization. Record locking is a key part of z/TPF application architecture, which allows multiple ECBs to make consistent updates to the z/TPF database without data loss or corruption.
Unit 5: Multiple ECBs running on multiple I-streamsThis unit describes how the z/TPF system manages multiple ECBs running on multiple I-streams.
Unit 6: CPU-intensive and long-running ECBsThis unit describes how the z/TPF system manages CPU-intensive and long-running ECBs.
