DSXchange

One of my Job sequences has only one stage: an "execute command" stage that calls a script called #pPathNameScrpt#/#pSed#, where both params are defined in the job properties box. This command never executes when I run the sequencer, though the run log shows the correct command being called, and a reply of 0. However, if I write out the entire path and script name w/o using any parameters, the correct command is actually executed on the server. Eventually, I will add more stages to the sequencer, but I'd like to get past this hurdle first.

I am wondering why I can't use the parameterized version of the execute command stage. The code below is the DS generated code for the sequencer, and I was hoping someone could review it. Isn't it fishy that the parameter values are never set?

Try it without the #'s.

Tried it.. didn't work. Any other ideas?

This stage does not work with parameters. It is documented with Ascential and an eCase has been opened. No work around as of yet. I believe they said it would be addressed in 7x.

The parms are not being evaluated and replaced with the value.

Nuts! But, thanks for the info.

I actually have several sequencers with similar "execute command" stages that do work, so I guess it's a hit or miss thing.. I wonder why sometimes the stage works and sometimes it doesn't.

- BP

Parameters in the command path are not supported since version 5, in case anyone is wondering.

I can't imagine that it has worked if you were passing parameters since this is a known issue since, as Ken states, version 5.

I created a job sequencer in which i have 2 jobs that has to be executed .
But its run only the first job. In the log it say 2nd job executed but i don't see the result. Which indicate that the 2nd job wan't executed.
This is with 7.x on unix

Thanks for all the input.

Below is an example of generated sequence code in which there are 2 execute command stages (at L$5$Start, L$6$Start) and one JobActivity(at L$4$Start).

In this example, both L$5 and L$6 use params to generate commands. L$5 always works (i.e. the before_count log gets created with the correct info), L$6 never works. I'm thinking that if I could figure out why L$5 works, I might be able to come up with a hack to make L$6 work. Any ideas?

Methinks you have a quotes issue:

For grins put this into a shell script and execute the shell script. It probably works. Pass the shell script your parameter values on the command line.

Ken,

Thanks for your help.

I do have a '#' issue on the #pInputFile param, but I fixed that and it still doesn't work.

I have tried doing:

sed '1d;$d' path/file >> path/newfile

and it works file..

Which set of quotes do you think is the problem? The set encasing the entire statement (it was generated by DS) or the single quote set around the sed option?

- BP

I have been burned in the past using embedded quotes within DSExecute, which is all a sequencer uses in its command stages. I try never to directly execute Unix commands unless they are basically very simple (mv, cat, rm, etc). You have little control over error handling in the command stages.

I prefer to have a shell script control the exceptional handling of whatever it is doing, then return the mindless pass/fail error value.

In your case, I'd put the sed statement into a shell script, complete with redirection nested in the script. This way, all DS has to do is run a script and give it command line parameters. Ex:

bigpoppased.ksh Put in your command stage:
#pathtoscripts#/bigpoppased.ksh as the command
path/file path/newfile as the parameters

You should see that the command doesn't find the path to scripts, unless your search path magically finds it.
