Re: Alternative to CPYF that doesn't apply a lock

I had a similar problem, and just wrote a quickie RPG program that reads the
source file and writes to the destination. If you have unique keys on the
destination file or any of its logicals, be sure to program for the
possibility.

Hi List

We have a program that makes use of the CPYF command to copy data from a
work file in QTEMP to a corresponding file in our data library.
Depending on the file being used there can be upwards to 100,000 records
being copied which is starting to cause a problem as the CPYF applies a
lock to the file being copied into.

The help text describes the restriction as:

o During the time a CPYF request is run, the file specified for
the To file (TOFILE) parameter may be locked (similar to an
*EXCL lock with no timeout) so that no access is possible.

Because the file is locked this is causing other programs to fail
CPF4128 and RPG1216 errors. I am thinking about putting in a change to
use an SQL insert instead of the CPYF and was wondering if anybody knows
whether or not using SQL would apply a lock to the receiving file.

Thanks in advance

Jonathan
