Comments on: Do we need to compile LF when its PF changes

If the format level identifier changes for a file, programs that open the file will need to be recompiled in order to avoid a level check.

It doesn’t matter how the file was changed. If a PF was changed with CHGPF and the related LFs received a new level ID, programs that open the LFs will need to be recompiled.

No .. since you’ve changed the physical file and the logical file structure you want the programs to fail!!! (what if you made the first field in the file one character wider…..).

Thought I learned something new today. Tried the CHGPF command and it worked fine. New fields were in both th PF and LF without having to recompile them. The only problem I found is you still get a level check on the programs using the LF.
Is there a way to avoid this with out setting the file to *LVLCHK *NO?

1. If you used the command CHGPF or SQL ALTER TABLE you will not need to recompile the logicals

2. If the logical has a field list you may want to add the field to the logical and recompile the logical.

A few questions:Have you Compiled the PF?Did you compile the PF in the same library as the dependant LF’s?Basically, in order to compile the PF you will need to delete the LF’s and recompile them after the PF has compiled. The the answer to you wuestion is Yes, you must recompile dependant Lf’s.
