How do I delete a printer in Linux?

Warning: As always, please exercise caution when performing system maintenance, especially when initiating processes that can potentially delete data.

  • Log into the server as root or become root
  • Delete printer from CUPS
    • NOTE: Replace lp1 with the name of the printer being configured (lp1, lp20, etc.)
lpadmin -x lp1
  • Delete UV driver file:
    • NOTE: Replace lp1 with the name of the printer being configured (lp1, lp20, etc.)
rm /usr/spool/uv/
  • Delete queue in UV (delete the line starting with LP1):
    • NOTE: Replace lp1 with the name of the printer being deleted (lp1, lp20, etc.)
vi /usr/spool/uv/sp.config
  • Remove the printer hostname (lp1) and IP address from the /etc/hosts file:
    vi /etc/hosts
  • Refresh the UV spooler:
usa -R
  • The printer is now  can be delete from the  Eclipse level

How do I access the PDW.DATA samba share from Windows:?

From any Windows PC you can access the windows direct share (the /u2/exports directory) by simply going to the main Start menu, choosing Run and typing in the hostname or IP address of your eclipse server.

For example:




You should then see the PDW.DATA folder as well as other Eclipse samba shares.

Meltdown and Spectre Vulnerabilities


Epicor Eclipse is aware of the Meltdown-Spector  vulnerabilities affecting many modern microprocessors from Intel, AMD, POWER and ARM chips that could allow hackers to access a computer’s memory and steal passwords, encryption keys and other private information from open applications.

Because it’s a vulnerability in the CPU hardware implementations, not a bug in the Eclipse application program, there is no “patch” from Eclipse.

We recommend that customers to check with their hardware and Operating System (OS) vendors for applicable patches as the solution for Meltdown and Spectre.

Epicor’s Response

  • Apply the firmware update via BIOS update
  • Apply the operating system (RHEL, Windows and AIX) patch
  • Apply hypervisor patches where applicable

Recommended Customer Actions

We recommend that customers to open a service request with Eclipse Systems support team and deploy patches on their platform and underlying infrastructure on a mutually agreed schedule.

Q: How do I patch my system?
A:Install Red Hat updates.
A:Install Dell Firmware Update.

Q: Will these fixes slow down my server?
A:  Yes, there is performance impact caused by additional overhead required for security hardening, but the actual performance degradation that customers see may vary considerably based on the nature of their workload, hardware configuration and system constraints.

Q: Can I disable these fixes?
A: Yes, you can disable the kernel patches if you fell confident that your systems are well protected by other means. Please see this article from Red Hat for a step by step instructions.


Eclipse Database Replication

UniVerse Database Replication


Eclipse HA

Data replication frequency: typically “real time”
Time to recovery: typically a few minutes

Eclipse customers that want “real time” replication can use UniVerse’s native replication functionality. The software is configured to capture writes to the database and replicate them to a secondary server while preserving the integrity of the database. Recovery is also quick, since the Eclipse software is already up and running on the secondary server. This solution is implemented and supported directly by the database vendor, Rocket Software, so please contact your account manager for more details.
