11. 11 2. Diagnostics The Definition of Metrics – Metrics are units of measurement used to assess the health of your system. Each target comes with a predefined set of metrics. These metrics in turn have thresholds associated with them. – Thresholds are boundary values against which monitored metric values are compared. For example, for each disk device associated with the Disk Utilization (%) metric, you can define a different warning and critical threshold. Some of the thresholds are predefined by Oracle, others are not. Overview

94. 94 Configuring Grid Control Administrators 1.About Groups Administrator

95. 95 Groups Grid Control groups are user-defined logical sets of targets that enable you to: ‧ Manage sets of systems as a single functional unit ‧ Quickly determine overall status and health of a subset of the grid’s managed targets ‧ Get summaries of open alerts and job activity ‧ Run Host and SQL jobs against group targets ‧ Apply blackouts, grant privileges, and set notification rules collectively to all group members Configuring

96. 96 Types of Groups ‧ Groups (generic) ‧ Database groups ‧ Host groups Configuring

97. 97 Creating Groups On the Home page, click Targets and then click Groups. ‧ Select the group type and click Go. ‧ Select the targets to include in the group. ‧ If the type is Group, also select Metrics. Configuring

98. 98 Monitoring Groups On the Group Home page, you can monitor all the targets in a group. Configuring

99. 99 Monitoring Group Performance You can monitor a group’s performance. Configuring

100. 100 Monitoring Group Targets You can monitor all the targets in a group. Configuring

101. 101 Super Administrator A super administrator has the ability to perform all of the following tasks: Select the group type and click Go. ‧ Create, modify, and delete any Grid Control administrator ‧ Create any role in the system ‧ Perform any action on any target in the system ‧ See all areas of the Management System primary tab Configuring

102. 102 Creating Administrators On the Grid Control Home page, click Setup, and then click Administrators. Configuring

103. 103 Creating Roles Super administrators create, grant, and revoke roles. Roles include: ‧ System privileges ‧ Targets ‧ Target privileges ‧ Administrators ‧ Other Roles Configuring

104. 104 Notifying Administrators About Issues ‧ Notifications help administrators resolve issues quickly by notifying them when certain conditions exist. ‧ The following items need to be defined for an administrator to receive notifications: –Notification method –E-mail addresses –Notification schedule –Notification rules Configuring

105. 105 Setting Up Notification Methods Notification methods define how an administrator is notified. Configuring

106. 106 Defining E-Mail Addresses E-mail addresses are used to send notifications to you. Configuring

107. 107 Defining a Notification Schedule Notification schedules determine who is notified when alerts or other issues occur. Configuring

108. 108 Using Notification Rules Notification rules act as filters to determine which notifications are sent to an administrator. Configuring

109. 109 Preferred Credentials Preferred credentials simplify access to targets that you manage. Preferred credentials are set for the following target types: ‧ Databases ‧ Host ‧ Listener Configuring

110. 110 Preferred credentials may be set, modified or deleted from the Preferred Credentials page. Setting Preferred Credentials Configuring

111. 111 Managing Target Subtabs Customizing Grid Control target subtabs to match your division of system responsibility. Configuring

112. 112 Troubleshooting When you want to collect tracefiles before making a TAR

113. 113 Troubleshooting When you want to collect tracefiles before making a TAR you could face a problem using DBconsole and could not find what caused it, please search it from Metalink first, then open TAR. In this case, OSS needs a clear problem description about what is happening now and well organized tracefiles with DEBUG mode. Setting DEBUG mode become effective after restarting DBconsole. DBconsole is dependent on Database but different serivce, this action does not affect Database service.

114. 114 When you want to collect tracefiles before making a TAR (Cont’d) 1. Stop DBconsole Service 2. Move the files in $ORACLE_HOME/ /sysman/log into another directory 3. Open $ORACLE_HOME/ /sysman/config/emomslogging.propertie s 4. Set log4j.rootCategory=WARN, emlogAppender, emtrcAppender To log4j.rootCategory=DEBUG, emlogAppender, emtrcAppender 5. Open $ORACLE_HOME/ /sysman/config/emd.properties 6. Set EMAGENT_PERL_TRACE_LEVEL=ERROR To EMAGENT_PERL_TRACE_LEVEL=DEBUG 7. Start DBconsole 8. Reproduce the problem 9. Compress all the files in $ORACLE_HOME/ /sysman/log and upload in on your TAR. 10. Unset DEBUG mode Troubleshooting
