Both those values are very small and should be raised immediately to improve performance, if nothing else. These numbers are not per-process but per-system so if you have more than a couple of jobs running at the same time they will quickly consume your available resources. Since you've stated that ...

Ravij, it is very important when posing sweeping questions like this to explain what you've already tried, otherwise we will assume that you haven't tried anything and are just looking for an easy answer. The concept of incrementatl aggregation is a relatively new one. Much, if not most, of the code...

khron, you won't need to split the job into multiple transformers - since if you initiate the run of a job you control whether the calling process waits for that job to complete or continues on without waiting. As I stated in my first mail, I don't have access to DS right now; but with just a little...

I re-read your original post, originally I just remembered your statement "it happens every time I run..." but then I saw that it was different places in the same sequence. This leads me to look at a system-level restriction with the number of concurrent files that can be open at any given time. If ...

Then I am almost certain that access rights are the culprit, especially since you have a shared container that can be used by different userids.

Ray, the site I am at has not only numerous machines but also several instances of DS on many of them. Although originally intended for temporary use during migration, they work out quite well. They are almost a 24x7 operation and "bouncing" a DS instance can take days to arrange, with more instance...

There are three basic approaches that you might take, the first one is the simplest for you: a) write a shell or awk script to read and parse the .CSV file into the parameter and then use the dsjob command line call to your DataStage job and pass the parameters to it. b) write a DataStage job that r...

The first likely cause is access rights - if another user created this hashed file and the umask wasn't set correctly, the userid you try to read/write to the file might not have sufficient UNIX permissions on the hashed file (if it is a type 30 Dynamic file, the path shown will be a directory under...

Ray - same thing for me; an 'urgent' compounded by a deliberate cross post in two forums equated to a "no answer".

Akrzy, see - progress already with Ray's response. Here's my 2-pence worth: The PX configuration specifies scratch devices. These are true scratch devices in that they won't be needed after a job finishes or aborts. So why use relatively expensive (in terms of I/O time) RAID constructs on them. If y...

Woah - if your "logical host" is the same as another virtual machine then you don't need to use a different memory address! You really only need to do this if two intances of DataStage need to co-exist on the same UNIX node; and from what I gather this is not the case.

You can only have one service running at a time, so you'll have to stop the Windows service before the DataStage one will work. If you really need both services at the same time you will have to read the documentation on changing the ports, I've never tried that before.

If the "logical host" is a distinct machine, with it's own IP address and nodename and it's own instance of UNIX then it should work. Basically the DataStage engine will use a reserved block of shared memory and communication ports, so if you wish multiple instances on the same machine you need to d...
