DSXchange

Of course, since the UniVerse source code is full of tried and true hashing algorithm, it would make sense that one of those were deployed.

The Dynamic file structure would be the logical choice as it supports keys of any type and length.

Craig is correct. 8.5 windows is still using "at" for scheduling.

How much CPU time is being used by your stage. User time is computation time, System time is either time spent doing I/O or Semaphore (System) activity, etc.

Mostly the Grid sites. I know of 4-5 sites. It would be nice to know if there are any other users of GRID on DSXchange

Go into the Datastage (UniVerse) environment within your project. You can do this by cd $DSHOME ; ./dsenv; ./bin/uvsh From there, execute a LOGTO PROJ_NAME Once there, there is a DS.TOOLS Menu (just enter DS.TOOLS at the prompt). One of the options in the menus is Rebuild Indexes. I have found this ...

Hi All, I'm looking for the larger Datastage sites. Don't need the name of the company (although would be nice), but System Config, and number of jobs executed on a daily basis would be great. Data volume would be fantastic but that may The site I'm working with is on a grid with 10 compute nodes an...

Has anyone setup multiple headnodes in a Datastage environment. We are executing on a grid and looking at upgrading from 1 headnode to 2 headnodes. Do we need 2 XMETA and Websphere environments or is it leveraging off of existing infrastructure? I'm not asking for the answer, but just a hint. I'm re...

As a rule of thumb, never EVER develop a Datastage job in enterprise with 1 node. Even if you have a small single core CPU, you are still able to develop jobs using 2 nodes. It may not run fast but performance is not the issue. When developing with 2 nodes, you exercise the parallel aspects of data ...

Are you going to have the two products co-exist or will you be replacing the 7.x release with an 8.x release? If you are replacing the 7.x with 8.x I would make sure you clean up the registry between the deinstall of 7.x and the install of 8.x. The Microsoft registry can get cluttered and may preven...

Thanks Ray. That what I thought. The IBM documentation says to shut down everything but I was pretty sure ASBnode was outside the realm.

Had to document it for my offsider however :)

I'm making a mod to the uvconfig file within the Datastage engine and performing performing a "uvregen" and restart of the engine with a uv -admin -start

Do I need to shut down and restart the ASBnode as well?

Thanks in advance,

There is a kernel patch for Linux for PDFLUSH. This is a known LINUX issue with EE.

My site has patched SUSE kernel for this, but it may be called something else in Redhat.

Every time you use a transformer stage, the data is exported, processed by the C++ code in the transformer and re-imported with data validation into the Datastage run machine.

This is a very expensive operation to perform 6 times. Instead use a Switch stage to segment the data.

I worked with a customer in Denver and they have scheduled a Datastage job in cron to run every 5 mins. It's not real-time but close. You could also write a unix script to check for the existance of a file within the directory in question, and if there are any files, submit the datastage job to proc...

And is there a technical question that can be answered in this forum :)

There is a forum for this type of post outside of the technical questions/answers forum.
