This video covers IMS DB repair techniques that are specific to HALDBs, such as re-creating the ILDS and primary index from the recovered DBDS.

This video describes standard IMS database recovery methods, application repair techniques, and correcting IMS database problems. The next video will look at specific considerations for HALDBs.

This video covers some database layouts that should be useful for you to understand how to repair and recover the IMS catalog database, specifically looking at:- Library Integrity utility DBD Map of…

This video provides an overview of the the structure and purpose of the IMS catalog, which is an IMS high availability large database (HALDB). The goal of this video series is learn how to repair and…

This video describes the candidates for HALDB, critical factors in the successful implementation of HALDB, and where to find more information about HALDB.

This video describes how performance can be affected by the OLR process.

This video describes the commands used to get information about the OLR process. The video also covers the data that is captured by logging during the OLR process.

This second video describes the online reorganization process: copying segments, application access, subsequent reorganizations, and creating output data sets.

This first video provides an overview of the benefits, environments, naming conventions, and more for online reorganization.

This video describes various HALDB considerations such as locking, logging, OSAM sequential buffering, data set groups, and data sharing.

This second video about application considerations describes initial loads with logical relationships and with secondary indexes, limiting a PCB to one or more partitions, and DL/I Calls with HALDB.

This first video about application considerations covers processing a secondary index as a database and initial loads.

This video describes the support for secondary indexes with HALDB and the limitations of adding secondary indexes with HALDB.

This second video continues the discussion about what changes that you can make to the database and partitions for HALDBs.

This first video describes changes that you can make to the database and partitions for HALDBs.

This video describes the HALDB Toolkit, which was formerly known as the IMS HALDB Conversion and Maintenance Aid. You can use this IBM product to help with the HALDB migration process.
