Re: pages are shuffled, " CHGQRYA DEGREE(*NONE) " what this command does?

CHGQRYA controls parallel query processing. Do you have SMP installed? That's Symmetric Multiple Processing, a licensed option of OS/400. If you do and the query does not have ordering specified, the records will be returned in unpredictable order. Setting DEGREE to *NONE forces no parallelism, hence, records are returned in arrival sequence (probably). It will be slower, however. The real solution, usually, is to use an ORDER BY in SQL or set up sort specs in Query/400.

I assume this command is in the source? If so, try running it on your command line before executing the query, and see whether it fixes things. If so, get a sort spec in there.

These is a strange error which is coming when user is trying to print a statement for some a/c.

The pages are getting shuffled.(1,2,3,81,82....)
The proc that  is being called is as below:
QS36PRC/ YXXBT3.

In this the first statement is a runqry

         RUNQRY     QRY(YQAC/YSELECT) QRYFILE((Y3.ST4 +
                      *FIRST)) RCDSLT(*YES) +
                      OUTFILE(QTEMP/YSLFAX)

I copied the query to my library and ran the query. The output is perfect.
But when you issue a runqry from command line(or program) the pages are getting shuffled.


Looks like if the number of pages(or records) are more we are encountering this.
and also I would like to know
what below command does?
CHGQRYA DEGREE(*NONE)

Thanks so much for your help,
Murli.
