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

[Tommy.Holden@xxxxxxxxxxxxxxxxxxxxx]

SQL doesn't place a lock on the file.  I've used insert, update and delete 
with SQL while the files have been locked via programs lots of times with 
no issues.

Thanks,

Alternative to CPYF that doesn't apply a lock



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
