Extract Job Name and Short Description for all Jobs

[Rangs]

Can someone please suggest how to extract all Job Names and its corresponding short description into a text file using a DataStage Job. Probably by querying the repository.

What Stage to use and whats the SQL ??.
What privilige is required to do such a task ??
What connection parameters need to be used in the source extraction stage ??

You can parse the exported dsx file.
But you can alternativly get these information from DS_JOBS.
But when I tried to get Description from DS_JOBS, I get the following error.

Code: Select all

DataStage/SQL: syntax error.  Unexpected symbol.  Token was "DESC"

Not sure, if we need get it by other means.
Hope Kim or Ray or someone else will answer this.

The descriptions are stored within the DS_JOBOBJECTS, not with the DS_JOBS, that's why you could not find it in DS_JOBS.

Try

Code: Select all

SELECT EVAL "@RECORD<4>", EVAL "@RECORD<7>" FROM DS_JOBOBJECTS WHERE OLETYPE='CJobDefn'

You can use a UV stage to extract the required records from the DS_JOBS table (the short descriptions ARE stored there, as well as in DS_JOBOBJECTS). The advantage of using DS_JOBS is that the relevant column names all exist in the metadata. Importing them into DataStage, however, requires a "trick", since this table is one of those explicitly blocked to the import process. Create a synonym in the project, for example MY_JOBS, and import the table definition from that.

Code: Select all

COPYI FROM VOC DS_JOBS,MY_JOBS

will create the synonym. When it's no longer required:

Code: Select all

DELETE FROM VOC WHERE @ID = 'MY_JOBS';

Ray the description field in DS_JOBS does not match the one in DS_JOBOBJECTS. I would create ShortDesc field before importing the metadata as Ray described. Here is the SQL for your UV stage.

Code: Select all

INSERT INTO DICT DS_JOBOBJECTS 
(
   FIELD, 
   CODE, 
   EXP, 
   NAME, 
   FORMAT, 
   SM
) VALUES (
   'ShortDesc', 
   'D', 
   '4', 
   'ShortDesc', 
   '64L', 
   'S' 
)
; 

Code: Select all

select
   DS_JOBS.NAME JobName FMT '40L',
   ShortDesc
from 
   DS_JOBOBJECTS, 
   DS_JOBS
where 
   DS_JOBOBJECTS.OLETYPE = 'CJobDefn' 
   and DS_JOBOBJECTS.OBJIDNO = DS_JOBS.JOBNO 
   and DS_JOBS.NAME = 'BuildEtlOleTypeHash'
; 

The DS_JOBS.NAME = 'BuildEtlOleTypeHash' needs to be removed but is good for testing.
