You will get this error if the Job Monitor is down. The job monitor is a seperate Java application that monitors running jobs on DataStage.
You can actually stop and start this job monitor.

If you changed your uvconfig values, for example the T30FILE, you would need to do uvregen. But you will probably get an error saying...
Disk shared memory size of 13187020 exceeds maximum allowed size of 11829248
This is because, the shared memory settings DMEMOFF also needs to be adjusted. But what is the right value?

This means that the number of opened dynamic files exceeded the settings in uvconfig. This may also due to hung process that wasn't relased from the table. Typically, a simple restart of the DataStage server will resolve this issue. But you may also want to increase the value of T30FILE from the uvconfig.
To change this value, edit uvconfig file. The default is 200. Bump it up to 500 and play with the settings over time. If you still received the same error, just adjust the settings again.

Here's a quick tip on how to get a date in string YYYYMMDD format from ETL DataStage server job. Apparently using Oconv(@DATE, "DYMD[4,2,2]") will not produce a date in YYYYMMDD format as expected. It will produce YYYY MM DD (with space in between).

This is a quick tip on how you would do date operation in a Parallel Extender job. The date needs to be converted first to Julian date which is an integer, then convert back to date after doing the mathematical operation.

A snowflake schema is a star schema structure normalized through the use of dimension tables. For example dimension table hierachies are broken into simpler tables. In star schema example we had 4 dimensions like customer, time, store, product and sales fact table.

The ETL process involves mapping the data between source systems and target database such as data warehouse or data mart. The source data then goes through cleansing in the staging area. Then, the last step is transforming cleansed source data and then loading it into the target system.
