Network Maintenance Document Transcript

  • 1. Network Maintenance In this document: • Backing Up Database Files, 1 • Installing Operating System Service Packs, 2 • File Server Opportunistic Locking, 2 • Sharing an OfficeMate and ExamWRITER Database, 2 • Using a Robust File Server, 3 • Verifying Network Connectivity, 3 • Persistent Database Corruption, 4 Note OfficeMate Software Solutions limits the support it provides exclusively to its own products and therefore does not provide assistance and support for any issues related to the backup and restoration of data or network maintenance. Backing Up Backup your OfficeMate and ExamWRITER database files on a regular basis! A full Database database backup is the best way to make sure that you can recover your OfficeMate and ExamWRITER database files in the event of a hardware or software failure, Files computer virus attack, fire, theft, or natural disaster. If your office is a networked environment, you must close all OfficeMate and ExamWRITER programs that are open before you backup your data. The integrity of your backup is severely compromised, and in some cases invalidated, if you perform a backup while OfficeMate and ExamWRITER are open. Network Maintenance 1
  • 2. Network Maintenance Installing Operating System Service Packs Installing If your office is in a networked environment, it is important to download the latest Operating operating system service pack to ensure that your network computers contain the latest bug fixes for the network redirector and file system. System Service Packs To install operating system service packs, follow the instructions below: 1 Go to http://windowsupdate.microsoft.com. The Microsoft Windows Update Web page opens. 2 Click Express Install or Custom Install. Microsoft looks for updates. 3 Click Install to install operating system service packs and other Microsoft updates. File Server Opportunistic locking (oplocks) can increase the risk of database corruption when Opportunistic two or more clients on a network file server share the file. Microsoft Windows NT 4.0, Microsoft Windows 2000, and Novell file servers that support opportunistic locking Locking are susceptible to oplocks. Microsoft Windows NT 4.0, Microsoft Windows 2000, and Microsoft Windows XP that connect to a file server that supports opportunistic locking are also susceptible. The sections below provide information on how to avoid oplocks in the following operating systems: • Microsoft Windows 2000, 2 • Microsoft Windows XP, 2 Microsoft Windows 2000 To avoid oplocks on computers that are running Microsoft Windows 2000, you must install Windows 2000 Service Pack 3 (SP3). Install SP3 on the Windows 2000 file server where the OfficeMate and ExamWRITER database files are located and on each Windows 2000 client computer that connects to the Windows 2000 file server. Microsoft Windows XP To avoid oplocks on computers that are running Windows XP, you must install Windows XP Service Pack (SP1). Install SP1 on each Windows XP client computer that connects to the file server where the OfficeMate and ExamWRITER database files are located. Sharing an If possible, do not share OfficeMate and ExamWRITER database files that are stored OfficeMate on a Microsoft Windows 95, Microsoft Window 98, Microsoft Windows Millennium Edition (Me), or Microsoft Windows 2000 file share with Microsoft Windows NT or and Microsoft Windows XP clients. When you have a mixture of computers on a network ExamWRITER with some computers running Microsoft Windows 95, Microsoft Windows 98, Database Microsoft Windows Me, or Microsoft Windows 2000 and some computers running Microsoft Windows NT or Microsoft Windows XP, and you have to share the database with other network users, Microsoft recommends that you store and share Network Maintenance 2
  • 3. Network Maintenance Using a Robust File Server the database files on a Microsoft Windows NT or Microsoft Windows 2003 server with opportunistic locking disabled. Corruption can occur if you have Microsoft Windows NT or Microsoft Windows 2003 client computers share a file that is stored on a Microsoft Windows 95, Microsoft Windows 98, Microsoft Windows Me, or Microsoft Windows 2000 file share. This corruption can occur even if the Microsoft Windows NT or Microsoft Windows XP clients have opportunistic locking disabled. Using a Ensure that you have a robust file server that can handle the number of users and the Robust File requests that are made to OfficeMate and ExamWRITER database files. Also, ensure that the file server is not overtaxed with handling many other processes, such as Server Windows Domain Controller, Exchange Server, and SQL Server. The network administrator or other server users may reboot the computer to fix a problem with another important service (such as the mail server) or after applying new software, a service pack, or hot fix and may forget that the Microsoft Jet Database Engine is currently shared on the server. Rebooting the file server causes an unexpected database client connection interruption and may cause database corruption. To prevent interrupted client connections, close the database before the file server is rebooted or before file server software updates are applied. Place a robust file server in a secure location where it cannot accidently be turned off. Ensure that the server has an uninterrupted power supply (UPS) to protect it from intermittent power outages and power fluctuations. Ensure that the network file server has high performance hard drives, a good network card, and plenty of RAM so that the server can handle the load that is placed on it. Verifying OfficeMate and ExamWRITER use the Microsoft Jet Database Engine file-sharing Network database. A file-sharing database is a database in which all of the file processing occurs at the client. When a file-sharing database is used in a multi-user environment, Connectivity multiple client processes use file read, write, and lock operations on the same shared file across a network. If, for any reason, a process cannot be completed, the file can be left in an incomplete or corrupted state. Two examples of when a process may not be completed is when a client is terminated unexpectedly and when a network connection to the server is dropped. Ensure that you have a stable and fast network with solid network connectivity to the network file server. Avoid using OfficeMate and ExamWRITER over a wide area network (WAN), wireless connection, modem connection, file transfer protocol (FTP), or any other less-than-reliable network transport. Because Microsoft Jet Database Engine is a file-sharing database system, unreliable network transportation increases the chances of a dropped client. A dropped client can greatly increase the chance of database corruption. Other symptoms of network connectivity problems include problems with printing to shared printers, browsing the Internet, and inconsistent workstation performance. Network Maintenance 3
  • 4. Network Maintenance Persistent Database Corruption Persistent If you have followed all of the above network maintenance suggestions, but database Database corruption problems and other symptoms persist, complete the following tasks: Corruption • Ensure that all of your network hardware is working properly. One faulty network card, cable, or hub/switch can cause database corruption. • Employee a trained networking professional to analyze your network traffic for problems. • Consider restoring your data from a successful backup or send the database to OfficeMate Software Solutions for recovery (additional fee required).
