Installing On Unix/Linux

OM Plus Delivery Manger can be installed on most commercial UNIX and Linux operating systems including, Sun Solaris 8, 9 and 10, HP-UX 11.x and greater, IBM AIX 5.1, 5.2 and greater, Red Hat Enterprise Linux Version 7 and greater, Red Hat AS/ES 3.0 and greater open source operating systems and other comparable Linux operating systems.

The OM Plus Delivery Manger installation process uses the uncompress command. Please ensure that the system is able to use this utility is installed or that a compatible utility has been linked in its place.

1. Download the appropriate install package for the system.

2. Unpack the package into an empty directory.

3. Run the following command.


( ./OMINSTALL\;1 for HP systems)

and follow the install prompts.

Starting the Daemons

  • For information on the daemons associated with OM Plus, refer to the following table.

Daemons Description
Admin Server Performs administrative system functions. The Client requires this to function correctly. To run, issue the dccbkadm command.
LPD Server Receives requests from other hosts using the LPD/LPR Protocol. To run, issue the dcclpdser command.
Network Status Used for remote communication. The Client requires this to function correctly. To run, issue the dccbkst command.
OM Plus Server Receives requests from another OM Plus application. To run, issue the dccompser command.
Scheduler Dispatches requests. OM Plus requires this to function correctly. To run, issue the dccsched command.
Remote Service Transfers printer definitions between OM Plus Servers. This service must be started from the command line by issuing the dccpingrem command. To stop it, the process must be killed.
Monitor Service Monitors and controls the status of the other services.

Starting the Daemons at Boot Time

  • The daemons can be set to execute automatically at boot time so the spooling services are automatically available. To do this, make symlinks in the rc startup directories and the init.d directory.

To set the daemons to start at boot time, run the following command:

# dcclplink

Setting the Unix Environment

  • For OM Plus to function properly, the environment variable LPHOME must be set to the base OM Plus directory (for example, /usr/lpplus), and the path must contain an entry for the OM Plus applications (for example, /usr/lpplus/bin). During the OM Plus installation, an entry is placed in the /etc/profile. To determine if the environment is set to use OM Plus, from the command line, enter #env.

The following example appears displaying the env command output with the OM Plus variables indicated in bold.










  • TERMCAP=/etc/termcap

Starting the Om Plus Unix Services

  • In addition to the environment variables, OM Plus adds the following lines to the services file.

Dccbkst 53971/tcp

OM Plus 53972/tcp

dcce2eser 53973/tcp

dccbkadm 53974/tcp

dccpingr 53975/tcp

Installing Over an Existing Version on Unix

If OM Plus is already installed on UNIX the new version can be installed while retaining all the user definitions set in the existing version. To install over an existing version, first stop all services (daemons), and then install the new version. To stop the daemons, run dccadmin and then from the services menu select the services to stop. For information, refer to dccadmin. Once all daemons are stopped, proceed to Installing on UNIX.
