Use PL/I to determine the algorithm for an IMS HALDB PSE
IBM Information Management System's High Availability Large Database (IMS HALDB) is a partitioned database, and a Partition Selection Exit (PSE) is an Assembler routine that is used to distribute records across the partitions. There is no way to prove if the algorithm in a PSE will provide a desired distribution without implementing the PSE beforehand. Since implementing a PSE affects database availability, a way is needed to evaluate PSE algorithms without affecting availability. This article describes an approach to evaluate algorithms using a High Level Language (PL/I) to produce a uniform distribution.

Exploring IMS disaster recovery solutions, Part 4: Coordinated IMS and DB2 solutions
Every customer needs a disaster recovery (DR) plan. The strategy will differ from one customer to the next. For IMS, there are two types of DR solutions: 1) IMS specific, and 2) Storage Mirroring. In this tutorial, we explore the IMS specific DR solutions. There are solutions that use only the IMS base product and solutions that use the IBM IMS Tools products. For each DR solution, there will be a discussion of the key concepts related to that solution.

Exploring IMS disaster recovery solutions, Part 3: IMS Recovery Expert solutions
Every customer needs a Disaster Recovery (DR) plan. The strategies used differ from one customer to another and they differ in time to recovery and loss of data. For IMS, there are five types of DR solutions: restart, recovery, recovery and restart, coordinated IMS and DB2 restart, and coordinated IMS and DB2 disaster recovery and restart. Here in Part 3, we explore both the recovery and recovery and restart solutions provided by the IMS Recovery Expert product.

Exploring IMS disaster recovery solutions, Part 2: IMS Base and IMS Tools recovery solutions
Every customer needs a Disaster Recovery (DR) plan. The strategies used differ from one customer to another and they differ in time to recovery and loss of data. For IMS, there are five types of DR solutions: restart, recovery, recovery and restart, coordinated IMS and DB2 restart, and coordinated IMS and DB2 disaster recovery and restart. Here in Part 2, we explore the recovery solutions that use only the IMS base functions and some of the functions in the IMS Tools.

Exploring IMS disaster recovery solutions, Part 1: Overview
Every customer needs a Disaster Recovery (DR) plan. The strategies used differ from one customer to another and they differ in time to recovery and loss of data. For IMS, there are five types of disaster recovery solutions: restart, recovery, recovery and restart, coordinated IMS and DB2 restart, and coordinated IMS and DB2 disaster recovery and restart. While the Storage Mirroring recovery solutions are classified as restart solutions, we will focus only on the non-Storage Mirroring IMS disaster recovery solutions in this series.

Finding and resolving IMS database exceptions using the Tools Base Administration Console for z/OS
The IBM Tools Base Administration Console for z/OS displays exceptions and statistical information in a graphical web interface. Because Administration Console provides access to database reports, historical trends, and displays exception messages, you can easily manage the overall health of your resources on a z/OS system. The following tutorial focuses on how you can manage a group of IMS databases and how to troubleshoot a problem when one of those databases has an exception.

Use Java in IMS dependent regions
This article helps IMS administrators, system programmers, and application programmers who are interested in using Java(R) within IMS dependent regions. This article highlights and gives examples of the steps needed to deploy Java in IMS dependent regions, including Java Batch Processing (JBP), Java Message Processing (JMP), and Message Processing Program (MPP) regions. The MPP example shows the capability to interoperate between COBOL and Java.

IMS solutions: Utilizing the IMS synchronous callout function to invoke a CICS Web service through IMS SOAP Gateway
This article uses a sample scenario to demonstrate how to use the synchronous callout function of IMS to invoke an existing CICS Web service through the IMS SOAP Gateway. The scenario takes an existing IMS application written in COBOL and enhances it to request additional information from an existing CICS Web service. The article provides an overview of the sample configuration, code samples, and step-by-step instructions on how to generate necessary artifacts. The article also provides information on how to troubleshoot problems you may encounter while recreating the scenario.
