The best-fit Java class for an Informix DATETIME value is java.sql.Timestamp. Java.sql.Timestamp technically inherits from java.util.Date; although, there are some semantic differences which are not typical of inheritance relationships. All the constructors, getters, and setters which are not deprecated for Date and Timestamp use values based on Greenwich Mean Time (GMT). They are offsets in milliseconds from the epoch, January 1, 1970 00:00:00 GMT. So, it would be logically consistent for Timestamps to convert to DATETIMEs using the GMT... [More]

At present most of the Informix configuration parameters can be modified dynamically. Typically, users run 'onmode -wf' or 'onmode -wm' command to dynamically change a specific configuration parameter. But there may be a situation when you need to modify multiple parameters at once. For example, you have ten Informix instance and want to tune some of SQL statement cache configuration parameters on all the Informix instances. Now, you can import a configuration file using onmode command to change multiple configuration parameter... [More]

This technote describes how the number of jobs that a DataStage project can have may be impacted by Operating Systems' limitations. When you reach the maximum number of folders the OS allows then you won't be able to create new jobs. Please refer to the technote that lists some suggestions about how to address this problem.
This a great resource to understand how to use APT_DUMP_SCORE and how to read scores in parallel jobs. This document written by the Development team uses a example to show the sections of a typical score and includes descriptions for every section, partition and operator notation, and even suggested self-training excercises Please refer to the published technote
