Hi All,

I am new to IMS(experienced in DB2 for z/OS), and trying to get familiar with regular tasks such as data refresh, backup, recovery, pcbgen, etc.


I am trying to understand how data refresh is done in IMS. In DB2 usually its through unload-load. My environment is having HALDB databases and IMS version is 12.

It will be helpful , if someone can give me steps(and if possible sample jcls) for doing data refresh in IMS.

Various methods.

You could do an unload/load.
If you have FileAid/IMS installed, you could do an extract/load.
If your production and test database definitions are the same, you could recover your test database from a production image copy.
You could write a program which extract the data from production and another program which will insert the extracted data into your test database.
