Requirement for Free Hard Drive Space

Make sure that there is sufficient space on the hard drive for the database. A minimum of 25 GB is

recommended as an initial amount of free hard drive space for the database. Additional space will

be needed as the database grows. You can manage the database size by periodically purging old

records. Kofax Documentation Exchange Server can also block database requests if the free drive

space reaches a specified threshold. For information about freeing hard drive space, refer to the

Kofax Document Exchange Server Administrator’s Guide.

Dedicated Server Requirement

Kofax Document Exchange Server should not be installed on a domain controller or a system with

Active Directory. OpenLDAP, which is installed with Kofax Document Exchange Server, conflicts

with the port used by Active Directory and generates the following error: “OPENLDAP

Deployment Failure.”

Registry Access

Kofax Document Exchange Server needs to modify the Registry during installation. If you are

using software that restricts changes to the Registry, turn it off while installing Kofax Document

Exchange Server.

program is running. Restarting the server will cause the installation to fail.
