- January 24, 1994
-
- The following Marketing and Support statement is being provided to
- customers currently using or considering using Novell's NetWare
- Name Service (NNS).
-
- Audience: Interested NNS customers upon request, NetWire, Product
- Information and Technical Support for release to
- customers inquiring about Novell's NNS Strategies.
-
- - NetWare Name Service (NNS) was first released to market in
- December of 1990. Since that date many sites have installed
- NNS primarily for the purpose of simplifying tasks related to
- network administration.
-
- - NNS was designed as an interim solution for customers wanting
- a simple naming service prior to the release of NetWare 4,
- which began shipping April 1993. NNS was not designed as a
- complete solution nor was it intended to be an alternative to
- Novell's Directory Service. For example, NNS does not offer
- time synchronization services, a vital part of NetWare 4's
- Directory Services which resolves conflicts when administering
- the directory services database.
-
- - NetWare 2.x/3.x customers who have not deployed NNS, yet who
- are planning to upgrade to NetWare 4.x in the future, are
- encouraged to upgrade directly to NetWare 4 rather than use
- NNS as a transition solution to get to NetWare's Directory
- Services.
-
- - At the present time, Novell has no plans to release further
- enhancements to NNS. Reported NNS bugs will continue to be
- addressed unless the reported problem requires a design change
- to NNS.
-
- - Currently, technical support for NNS is provided by
- 1-800-NETWARE (internationally 801-429-5228). Engineering
- support, which includes bug fixes to NNS utilities, is also
- available through 1-800-NETWARE (internationally
- 801-429-5228). Design changes and product enhancements are no
- longer available for NNS.
-
- - NetWare 4 was released in April, 1993. NNS customers have
- until October 31, 1994 to migrate their NNS domains to NetWare
- 4. At that time all Technical and Engineering support for
- NNS, including bug fixes, will be withdrawn.
-
- The following guidelines and restrictions apply to NNS. These are
- additional guidelines to those contained in the NNS documentation.
-
- 1. Synchronization for binderies within an NNS domain should be
- performed from a single administration workstation at a time.
- Simultaneous synchronization from multiple nodes can cause
- bindery corruption. Consult the NNS manual for a list of
- utilities that may synchronize the binderies within an NNS
- domain.
-
- 2. NNS employs no real time synchronization services to manage
- bindery modifications in the NNS environment. Multiple points
- of administration for a single NNS domain should be avoided.
- Locating NNS domains across remote locations should also be
- avoided.
-
- 3. NNS "toggles" connection 8 when administering domains with
- more than 8 servers. (i.e. connection 8 is used to update the
- 8th server in the domain then the 9th, then the 10th, etc.)
- Care should be taken to insure that connection 8 is free
- before initiating domain administration tasks for domains with
- greater than 8 servers. Due to the number of difficulties
- experienced by some NNS sites, Novell no longer recommends
- extending NNS domains to include more than eight servers per
- domain. Active NNS sites with more than 8 servers per domain
- are encouraged to consider reducing the number of servers in
- their domains.
-
- 4. Due to the number of difficulties experienced by some NNS
- sites, and also due to performance issues related to domains
- with large numbers of objects, Novell no longer recommends
- extending NNS domains to include more than 1,000 objects
- within a single domain. In order to facilitate manageability,
- NNS sites with more than 1,000 objects per domain are
- encouraged to consider reducing the number of objects in their
- domains.
-
- 5. Adding a file server to a domain or synchronizing file servers
- within a domain has been known to cause random password
- assignment to user accounts.
-
- 6. Synchronization performance on an NNS network may be affected
- by a number of factors. These include:
- - the number of file servers in the domain
- - the number of bindery objects (users and groups)
- within the domain
- - the physical layout of the network
- - the speed of both the server and the client
- involved in the synchronization process
-
- Using NNS with a large number of file servers, a large number
- of bindery objects, or in a WAN environment is not recommended
- and can result in poor performance. The use of multiple
- domains may help alleviate these problems.
-
- 7. Due to potential conflicts in bindery administration, NNS may
- be susceptible to bindery corruption. Bindery corruption on
- file servers within NNS domains can manifest itself in a
- variety of ways. Network administrators should be especially
- vigilant to make sure their binderies are free of corruption.
- If bindery corruption occurs, administrators should use the
- latest version of bindfix off of NetWire to solve the problem.
-
- 8. Some sites utilize NNS domains primarily to allow users within
- the domain to submit print jobs to a single domain print queue
- which is then serviced by a single domain printer. Such sites
- may also wish to consider utilizing printing services, such as
- the NetWare Print Server NLM, to concurrently service print
- queues located on different servers.
-
- The following guidelines and restrictions apply when using NNS in
- conjunction with Novell's recently released NCP Security Signature.
- These are additional guidelines to those contained in the NNS
- instruction manual and the NCP Security Signature documentation.
- Failure to follow these guidelines may result in binderies within
- an NNS domain becoming "out of sync".
-
- 9. When any server in an NNS domain is set to NCP Security
- Signature level 3, all clients within the domain should be set
- to level 1 or higher. Clients running at level 0 cannot
- synchronize servers running at level 3.
-
- 10. Likewise, when any client in an NNS domain is set to NCP
- Security Signature level 3, all servers within the domain
- should be set to level 1 or higher. Servers running at level
- 0 cannot be administered by clients running at level 3.
-
- The following guidelines apply to NNS domains that will be upgraded
- to NetWare 4.x Directory Services (NDS). Please refer to NetWare
- 4.x marketing and technical information and related product
- documentation for a better understanding of the concepts presented
- here.
-
- 11. With the release of NetWare 4.0, Novell has withdrawn NNS from
- the price list. NNS was intended as an interim naming service
- for those customers wishing to administer multiple 3.x and 2.x
- servers. It was not intended that long term support be
- provided to NNS.
-
- 12. Novell will end technical support for NNS on October 31, 1994.
- Existing NNS sites have until October 31, 1994 to fully
- migrate their NNS domains to NetWare 4.x. Customers with
- existing NNS licenses are encouraged to take this into account
- when adding new NNS domains or adding additional servers and
- users to existing NNS domains.
-
- 13. To facilitate manageability and to avoid service problems when
- upgrading NNS to NDS, Novell recommends that all servers
- within the NNS domain be migrated to 4.x with the same time
- frame. To simplify the upgrade to NDS, customers using NNS
- are encouraged to plan and properly size their NNS domains
- prior to beginning a migration to NDS. If an entire NNS
- domain cannot be migrated to NDS within the same time frame,
- customers may wish to resize the NNS domain prior to doing the
- upgrade to NetWare 4.x.
