Printing out the context

This recipe here is for completeness rather than because it is in any way complex.

Getting ready

Open the jo_cook_ch10_0080_tContextDump job.

How to do it...

The steps for printing out the context are as follows:

1. Open the Context tab, and you will see a set of context variables.

   

2. Drag a tContextDump component from the palette.

3. Attach a tLogRow component.

4. Run the job.

How it works...

tContextDump simply dumps all the context variables defined within the job into a flow that can then be logged via tLogRow.

There's more…

This component is most useful when running code that has been deployed to a server, because the log information is usually stored in a file. This allows us to check the values of the context variables at the time of execution that would otherwise be hidden from us. This is invaluable for debugging a deployed process that has failed.

Tip

Often, contexts contain sensitive information, such as user names and passwords to system resources. If you do not want these to...
