Question: I have defined some external stored procedures using Microfocus Cobol in my database and every time I make a change to them, I have to shut down DB2 to get the new version picked up. Is there any better way to do this?
This is true for all external routines that use external,
In Part 1, I talked about some of the first steps that a developer should go through when it comes to tuning queries. In this article, I will go through the initial steps in evaluating a SQL query using the Db2 explain output.
When it comes to tuning a query, program, or even an application that most developers are not sure where to begin or what may be causing response time issue(s). This article is here to help!
A database lock is a mechanism utilized by Db2 to govern the access to a database object amongst different transactions. This article describes the locking mechanism for Db2 (for LUW).
Locking and latching are both key mechanisms employed by relational database management systems to ensure data integrity, consistency, and the serialization of resources. In the Db2 for z/OS IRLM manages the locks, but both Db2 and IRLM have internal latches.
