Manually configure the Oracle 10g EM dbconsole

Overview When you choose to create a preconfigured database during the Oracle 10g installation, you can select the Oracle Enterprise Manager (OEM) interface that you want to use to manage the database. The following options are available: Database Grid Control This option is available only if an Oracle Management Agent is installed on the system. When the Installer detects an Oracle Management Agent on the system, it allows you to choose this option and specify the Oracle Management Service that you want to use to manage the database. If an Oracle Management Agent is not installed, you must choose to use Database Control to manage the database. However, if you install Oracle Management Agent after you install Oracle Database, you can then use Grid Control to manage this database. Database Control This option is selected by default if an Oracle Management Agent is not installed on the system. However, even if a Management Agent is installed, you can still choose to configure Database Control to manage the database. Custom installation If you choose the Custom installation type or the Advanced database configuration option during the installation, the Installer does not display the OEM setup screens. Instead, it runs the Database Configuration Assistant (DBCA) in interactive mode, which enables you to create a custom database. DBCA also enables you to specify the Oracle Enterprise Manager interface that you want to use. Furthermore, you can also use DBCA after the installation to configure Database Control for a database that was not previously configured to use it. However, if you decide to setup your own Database, you must install the Database Control manually. Setup your own Database and manually install the Database Control The Database Control relies on various underlying technologies to discover, monitor, and administer the Oracle Database environment. From the Database Control, you can monitor and administer a single Oracle Database instance. The Database Control Framework consists of the Database Control and its underlying technologies: A local version of the Oracle Management Service designed to work with the local database or clustered database. A local Oracle Management Repository installed in the local database and designed to store management data for the Database Control.

The following steps have to be performed. Create your own Database More information to setup your own Database can be found here: For Windows 2000 For Linux Create the Database Control Repository and setup the OC4J Application Server Make sure, that you can connect to the Repository Database (Test it with SQL*Plus). Examples for Setup Files can be found here: Windows Linux LISTENER.ORA listener.ora SQLNET.ORA sqlnet.ora TNSNAMES.ORA tnsnames.ora Now start the Oracle EM dbconsole Build Script ($ORACLE_HOME/bin/emca for Linux and $ORACLE_HOME/Bin/emca.bat for Windows). $ emca -repos create $ emca -config dbcontrol db STARTED EMCA at Fri May 14 10:43:22 MEST 2004 Enter the following information about the database to be configured.

Troubleshooting If you have troubles to connect, check your local configuration which can be found in $ORACLE_HOME/<hostname>_<SERVICE_NAME>. For Example our DbConsole Setup Directory looks as follows: $ pwd /opt/oracle/product/10.1.0/akira_AKI1/sysman/config $ ls -l -rw-r--r-- b64InternetCertificate.txt -rw-r--r-- emagentlogging.properties -rw-r--r-- emd.properties -rw-r--r-- emomsintg.xml -rw-r--r-- emomslogging.properties -rw-r--r-- emoms.properties -rw-r--r-- OUIinventories.add The most important file is emoms.properties, where you can find all the configuration parameters. #Fri May 14 10:54:49 CEST 2004 oracle.sysman.emSDK.svlt.ConsoleServerName= akira_Management_Service oracle.sysman.eml.mntr.emdRepPwd=0b878f6184e8319d emdrep.ping.pingCommand=/bin/ping <hostname> oracle.sysman.eml.mntr.emdRepPort=1521 oracle.sysman.eml.mntr.emdRepDBName=AKI1.WORLD oracle.sysman.emSDK.svlt.ConsoleMode=standalone oracle.sysman.emRep.dbConn.statementCacheSize=30 oracle.sysman.db.isqlplusUrl= http/://akira/:5560/isqlplus/dynamic oracle.sysman.emSDK.svlt.ConsoleServerPort=5500 oracle.sysman.eml.mntr.emdRepRAC=FALSE oracle.sysman.emSDK.emd.rt.useMonitoringCred=true oracle.sysman.eml.mntr.emdRepPwdEncrypted=TRUE oracle.sysman.db.isqlplusWebDBAUrl= http/://akira/:5560/isqlplus/dba/dynamic oracle.sysman.emSDK.svlt.ConsoleServerHost=akira oracle.sysman.emSDK.svlt.ConsoleServerHTTPSPort=5500 oracle.sysman.eml.mntr.emdRepServer=akira oracle.sysman.eml.mntr.emdRepSID=AKI1 oracle.sysman.emSDK.sec.ReuseLogonPassword=true oracle.sysman.eml.mntr.emdRepConnectDescriptor= (DESCRIPTION/=(ADDRESS_LIST/= (ADDRESS/=(PROTOCOL/=TCP)(HOST/=akira)(PORT/ =1521)))(CONNECT_DATA/=(SERVICE_NAME/=AKI1))) oracle.sysman.eml.mntr.emdRepUser=SYSMAN oracle.sysman.db.adm.conn.statementCacheSize=2 oracle.sysman.db.perf.conn.statementCacheSize=30 Automatically start and stop the DB-Console $ emctl start dbconsole $ emctl stop dbconsole $ emctl status dbconsole Oracle Enterprise Manager 10g Database Control Release 10.1.0.2.0 Copyright (c) 1996, 2004 Oracle Corporation.
