10.1 Maintenance Policies

Do not directly run the halt command (in Solaris) or switch off the power. In this way,irretrievable damages may occur on the DMS.

To ensure the stable and reliable running of the DMS, comply with the following:

z It is recommended to configure an Uninterrupted Power Supply (UPS) on the DMS WSto protect the system against hardware corruption, system crash and data loss due to theunexpected power failure.

If the DMS server cannot be configured with the UPS, after being informed that the

power will be shut down, the administrator must close the DMS server in the correct waybefore the WS is powered off.

z Whenever you need to power off the DMS WS, follow the sequence: exit the DMS, exitthe database, and run the init 6 command to restart the WS.

z After the system is started, run two applications, that is, the client and the SystemMonitor.

These two programs do not need to be closed, so that the administrator can monitor thesystem status at any time.

z The accounts of the NMS WS need to be divided according to their level and are grantedto the maintenance personnel.

The password of the administrative level account is only granted to the maintenance

personnel.z Do not play games on the DMS server, do not install other unnecessary software or do

not use it for other purpose.

z Do not connect any other computer or portable computer to the network where the DMSserver is to avoid the problems, such as the IP address conflict or virus infection.

z Keep the equipment room clean and dry.

10.2 Routine Maintenance List

Routine maintenance is preventive maintenance.According to different period, themaintenance is divided into daily, weekly, and monthly maintenance.

In the command, the /dev/rmt/0n indicates the tape that is used for backup.

It is recommended to back up at least the Solaris system files as follows.

If you cannot find the files /etc/defaultrouter and /etc/Routes, you need not to back up thesetwo files.

/etc/hosts

/etc/netmasks

/etc/nodename

/etc/hostname.*

In the file name, the "*" is the name of the network card, such as ce0. You can view it by the ifconfig a

command.

/etc/net/ticlts/hosts

10.4.4 Backing Up the Database Manually

Description

You can manually back up the configuration data of the DMS database as required to reducethe loss of data in some accident and to recover the DMS as soon as possible.

To reduce the workload of the routine maintenance, it is recommended to back up all DMS

database data. The scheduled backup mode is primary and the manual backup mode issecondary.

Procedure

Step 1 Start the database backup tool and log in to the server to be configured.Step 2 Choose Configuration > Database Set and create the set of all databases.Step 3 Choose Configuration > Backup Device and modify the path of the backup device.Step 4 Choose Operation > Manual Backup and manually back up the DMS database.

For operation details, refer to section 9.2 "Manual Backup."

$ su

Password:

Step 3 View the current server time and run the commands as follows:# date

Step 4 This step is optional. If some abnormity occurs, perform the following:z Modify the server time.

For details, refer to Chapter 1"Setting the NMS."

z In the case that NTP is abnormal, reset the NTP service.For details, refer to section "8 NTP Configuration."

Abide by the following principles to clear the user rights:

z Delete the useless user name in time.z For the new added devices, grant rights to the users who maintain the devices.z Strictly group the user rights according to the user group and operation set. Set the users

who have the same rights to the same group. Do not grant rights to a single user toreduce the effect on the NMS performance.

----End

10.5 Monthly Maintenance
