Open Enterprise Server [1] (OES) is a server operating system published by OpenText. It was first published by Novell in March 2005 to succeed their NetWare product. [2]
Unlike NetWare, OES is a Linux distribution—specifically, one based on SUSE Linux Enterprise Server. [3] The first major release of Open Enterprise Server (OES 1) could run either with a Linux kernel (with a NetWare compatibility layer) or Novell's NetWare kernel (with a Linux compatibility layer). [2] Novell discontinued the NetWare kernel prior to the release of OES 2, but NetWare 6.5 SP7, and later SP8, can run as a paravirtualized guest inside the Xen hypervisor (officially supported until 7 March 2012, Novell self-supported until 7 March 2015).
Novell released OES 1, the first version of OES, on 25 March 2005. [2] Since some users wanted backward compatibility with NetWare, Novell offered two installation options: OES-NetWare and OES-Linux. These are two different operating systems with different kernels and different userlands.
OES-NetWare is NetWare v6.5 equipped with NetWare Loadable Modules for various Novell services (such as NetWare Core Protocol, Novell eDirectory, Novell Storage Services, and iPrint) and open-source software (such as OpenSSH, Apache Tomcat, and the Apache HTTP Server). [4]
OES-Linux is based on the SUSE Linux Enterprise Server (SLES) with added NetWare services ported to the Linux kernel: e.g. the NetWare Core Protocol, Novell eDirectory, Novell Storage Services, and iPrint.
Novell released OES 2, the second version of OES, on 12 October 2007. It was the first SLES-Linux-kernel-only OES, but it retained the OES-NetWare operating system option, as NetWare 6.5 SP7 can run as a paravirtualized guest inside the Xen hypervisor. The SLES base of the OES 2 was later updated to SLES 10 SP1.
Features introduced in OES 2 include: [5]
See also (based on different OES editions):
OES 11 was released on 12 December 2011 based on SLES 11 SP1 64-bit. The NetWare Kernel was removed after OES 2. This is the first version of OES to be 64-bit (x86_64) only. NetWare 6.5 SP8 was still possible to run as a 32-bit only para-virtualized guest inside the Xen hypervisor.
Micro Focus released OES 2018 in November 2017, with three service releases (the last being OES 2018 SP3 in July 2021). All releases were all based on SLES 12 and its service packs.
While SUSE was sold by Micro Focus in 2018, [9] SLES support and updates are included with an OES installation, provided at least one OES component is installed.
OES 2023 was released in October 2022, using a base of SLES 15 SP4. It includes a new Unified Management Console (UMC) to supersede iManager for server management, TLS 1.3 support and was bundled with NetIQ eDirectory 9.2.7. [10] Breaking with previous convention, OES 23.4 (rather than SP1) was released in October 2023, and was rebranded to OpenText, [11] after their purchase of Micro Focus earlier in the year. General support was extended to 3 years from the usual 2 years of previous releases. [12]

Novell, Inc. was an American software and services company headquartered in Provo, Utah, that existed from 1980 until 2014. Its most significant product was the multi-platform network operating system known as Novell NetWare. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide.
NetWare is a discontinued computer network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a personal computer, using the IPX network protocol. The final update release was version 6.5SP8 in May 2009, and it has since been replaced by Open Enterprise Server.
IPX/SPX stands for Internetwork Packet Exchange/Sequenced Packet Exchange. IPX and SPX are networking protocols used initially on networks using the Novell NetWare operating systems. They also became widely used on networks deploying Microsoft Windows LANs, as they replaced NetWare LANs, but are no longer widely used. IPX/SPX was also widely used prior to and up to Windows XP, which supported the protocols, while later Windows versions do not, and TCP/IP took over for networking.
Btrieve is a transactional database software product. It is based on Indexed Sequential Access Method (ISAM), which is a way of storing data for fast retrieval. There have been several versions of the product for DOS, Linux, older versions of Microsoft Windows, 32-bit IBM OS/2 and for Novell NetWare.
UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis. UnixWare is typically deployed as a server rather than a desktop. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed as a server operating system.
M+NetMail was an ISP-grade E-mail package by Messaging Architects. It was designed to deliver scalable messaging and calendaring services, using Internet-standard protocols, across a large enterprise, or to a large group of users who are not particularly associated. The original name for the product, when owned by Novell, was Novell Internet Messaging System (NIMS). Messaging Architects showcased NetMail on its MyRealBox website, this service was discontinued on June 1, 2011.

AppArmor is a Linux kernel security module that allows the system administrator to restrict programs' capabilities with per-program profiles. Profiles can allow capabilities like network access, raw socket access, and the permission to read, write, or execute files on matching paths. AppArmor supplements the traditional Unix discretionary access control (DAC) model by providing mandatory access control (MAC). It has been partially included in the mainline Linux kernel since version 2.6.36 and its development has been supported by Canonical since 2009.
