Parallel tasks during DB2 for Z/OS Copy

We are copying over a thousand tablespaces using LISTDEF. The Copy
utility is restricting the parallelism to 6, even though Parallel 20
is specified.

Environment:
Z/OS R1.4 in 64-bit mode
DB2 V7
LPAR has 8GB and 2 Logical processors
Job has Region of 64MB (changing this doesn't seem to make a
difference)

Job output has message:
DSNU397I DSNUBBID - NUMBER OF TAKSS CONSTRAINED BY VIRTUAL STORAGE
DSNU427I DSNUBBID - OBJECTS WILL BE PROCESSED IN PARALLEL
NUMBER OF OBJECTS = 6

If we run multiple jobs instead of a single job, we can half the
elapse time.

Does anyone know how to get the Copy utility to increase the
parallelism?

Please post all replies to the newsgroup.

Thanks in advance,
Norm

I came up with what I think is a good idea for making multithreading programming easier in any .NET language. I dont know where else to post it, so I'll try here. ..NET 2.0 adds the capability to write anonymous functions, it would be nice if there was a "parallel" statement, that could simplify writing threadprocs. e.g. (theoretical c#) public void DoSomeParallelStuff() {

Hi, actually I have a childform, which runs a self-written script interpreter (runs aprox. 1 min). I want to create more child-forms and I want to have the interpreters run parallel. Right now only the interpreter of the last created form is running until it is finished and then the other ones are continuing. How can I make parallel working child-forms

I'm doing some analysis that is readily broken up into many independent pieces, on a multicore machine. I thought it would be best to just queue like 1000 of these pieces in the ThreadPool, and let that object take care of running them in the background on the machine's free cycles. But I need the program to wait for all the queued pieces to finish before it continues. I tried giving each work item a ManualResetEvent and using...

Has anybody tried to run parallel python applications? It appears that if your application is computation-bound using 'thread' or 'threading' modules will not get you any speedup. That is because python interpreter uses GIL(Global Interpreter Lock) for internal bookkeeping. The later allows only one python byte-code instruction to be executed at a time even if you have a multiprocessor computer. To overcome this limitation, I've created...

If you are firing that many queries you better be using bind variables and parsing the query once and rebinding, and executing many times and NOT closing the cursor. Doing that will help you immensely lower CPU usage. You are sending the queries sychronsly and the type of queries you are sending are not suited for doing parallel queries on (" single row from the a table and uses the primary key in its WHERE predicate"). Parallel queries...

Hello all, I have got the pseudo-code below that I would like to convert to c language. The algorithm calculates Pi value. I am somewhat familiar with C language, but I am just starting to learn parallel programming. In this specific example, the idea seems to be simple: one must subdivide the main loop into pieces that can be executed by independent "tasks" (computers??). Then, each "worker task" executes a part of the loop a...
