Take the 2-minute tour ×  The file /var/local/odbc/DDODBC.DAT is
being created/accessed on some (not all) servers when the
database is accessed via Perl dbi:ODBC.  I did a full crawl
through /var/local/odbc on a server that does create the file
and a server that does not, and everything is identical (md5sum)
save for the existence of that file. There is no difference in
the environment and the odbc.ini and odbcinst.ini files are also
the same.  I'm currently at a loss. I'm interested because this
file caused a db issue that was resolved by force-removing this
file.  share|improve this question  1 Answer 1  up vote 0 down

file DDODBC.DAT is (typically) created when there is a licensing
conflict on the host. In our case, our license is for servers
with a maximum of 16 CPUs, however we installed the driver on a
host with 24 CPUs. The driver realized this, made note of it
(with DDODBC.DAT), and will, eventually, switch itself into
evaluation mode.  sh
