Hi All,

Can any body will suggest me ow to add enviornment variable in datastage parallel job.

Could you explain bit more on you question.
You can add User defined Variable through Datastage Adminstrator client.
And you can use the same in jobs, optionally with $PROJDEF default value.
$ENV is used to access the OS variables in you jobs.

Hi,

Actually I want to assign some values to the enviornment variables from a particular job during run time and I want to refer these values in the sequence job.
please let me know whether it will work or not.

you can create the env variable under user-defined category either in the job properties option or in the DS administrator and can pass defalut values during run time.

okay.
but there are several options avaliable in job properties like

1-general
2-parallel
3-compiler
4-operator specific
5-reporting

so please be specific how I have to add the enviornment variable.

I am using recent 7.5x ds version parallel job in unix platform.
Another thing can reffer these variables in sequence job.

please suggest me.

Go to parameters tab in job properties, you will find Add Environment Variable bottom right, click on that and hit on New. Follow the commands then.

I don't believe the question as asked is being addressed:

It's not about creating and using variables during runtime but about creating and setting variables during runtime.

Carry on.

Do you mean:
(a) add a new environment variable that a job can use as a job parameter?
(b) add an environment variable to a job as a job parameter?
(c) change the value of an environment variable while a job is running?
(d) something else?

The first requires use of the Administrator client or editing the EnvVarDefns section of your DSParams file (which has implications for promoting into test/production).

The second involves clicking the Add Environment Variable button in the job's properties (Parameters tab).

The third is unsupported.

The fourth involves you responding to this post.

Hi Wurlod,

Sorry for late reply.

Actually I want to pass values of some attributes to the enviornmental variable in a parallel job so that I can reffer these values in the sequence job to use in the email notification activity.

So will you please tell me for this purpose how I have to add the enviornmental variable and pass the values to those variables.

Isn't that (c) in Ray's list? If so, you're going to need to take another path.

Hi Craig,

About which path you are telling.
Please mention

Forget about my 'path' statement. You need to resolve the confusion about what exactly it is you are trying to accomplish. Ray posted a list of four possible meanings - which one is correct? Any? None?

To me, it sounds like (c) which is the third item in his list and as mentioned, it is unsupported. Hence my assertation that - if (c) is the answer - you'll need to find another way to solve your problem.

Hi,
You can take the option (d) (something else)from ray's given options..
Actually I want to assign values to the ENV from a job.
And that value will be reffered in the sequence job.
If without ENV my problem can be solved then please suggest.

Its similar to passing values between jobs. Write your value to a flat file and in the sequence job activity, define a parameter to the job that needs to read that value. In the derivations you can call a small routine that cats the file and reads its contents using DSExecute().

Umm... that's (c).

As noted, pass this value via a flat file or User Status.
