GregBefore doing the RUNQRY, execute STRDBG without any program. Then you will get messages in your job log that will say why the optimizer took the action it did - create a copy.
Is FILENAME the PF name of the LF name? When you use RUNQRY like this, I'm not sure what happens.
You might try DYNSLT on the LF. If it helps, keep it. Look it up in InfoCenter for what it does.
The STRDBG is the most important thing to do first. HTH Vern At 08:14 AM 8/16/2005, you wrote:
I created a logical file over a rather large physical file to help speed up a long running program. I'd like to look at the data retrieved by the logical file so I can get ready to test the changed program. When I do RUNQRY *N FILENAME the system returns "Query running. Creating a copy of file FILENAME in LIBNAME". This grinds away for a long long time and I have to kill my session. >From Google I find that this message comes from OPNQRYF. The question is what's going on here? If there is an access path created by the CRTLF command why doesn't it just display the data? Other logical files instantly display records. The DDS for the LF does contain select and omit directives. Is that any significance? I don't think the program will run quicker if the operating system is going to build its own path to the data.
