Re: Use of PF or LF as Work files

[rob@xxxxxxxxx]

How is the physical file created?  From DDS?  Is there an access path in 
the physical that is actually used in the process that puts data into it? 
If not, then use the access path defined in one of your logicals.
Tis a rare case that is improved by taking the physical and creating 
another physical from it versus just putting a logical over it.  Not that 
it doesn't happen, however.

Oh, there are sometimes that you can create some usable access paths 
without the use of SQL or DDS.  For example:
DSPUSRPRF USRPRF(*ALL) OUTPUT(*OUTFILE) OUTFILE(MYLIB/MYFILE)
CHGPF FILE(MYLIB/MYFILE) MAXMBRS(1)
ADDPFCST FILE(MYLIB/MYFILE) TYPE(*PRIKEY) KEY(UPUPRF)
RGZPFM FILE(MYLIB/MYFILE) KEYFILE(*FILE)
You cannot add a constraint against something in QTEMP though.
Nothing to stop you from getting fancy
ADDPFCST FILE(MYLIB/MYFILE) TYPE(*PRIKEY) KEY(UPPWCD UPPWCT UPUPRF)

Use of PF or LF as Work files






I noticed in this old process, one program creates the work file (PF) and 
the next pgm creates a Work file logical, and then prints the report off 
of this logical. Is there any benefit to this, could there not be a PF 
work file to print or would this take longer? The logicals are used 
previously bec. there are several print programs however mine is not part 
of that group.
