4 1 Overview This document describes the configuration information you should pay attention to when you install an Oracle Database 11g R2 for IMC on the Linux operating system and after the installation. The database version used in this guide is Oracle Database 11g R2. If you are using a different Oracle database version, the configuration procedure may differ slightly. Before installing IMC, install Oracle Database 11g R2 first. Then restart the operating system, and proceed with the IMC installation. This guide only provides a generic Oracle database installation procedure. You can configure your Oracle database based on system software and hardware to achieve optimized performance. For more information, see the Oracle Database Installation Guide, Oracle Database Quick Installation Guide, and Oracle Universal Installer and OPatch User s Guide at Currently, you can install the database on a separate database server and save the IMC data on the database server. To install the database on a separate database server, follow these guidelines: On the IMC server, install an Oracle client with the same version as the database. Create a data file folder on the database server before you start the installation. When deploying the IMC components, you can input the local path to the folder. 1

5 2 Preparing for Installation CAUTION: Type rather than copy and paste commands during database installation to make them correctly recognized. A 32-bit operating system must use the 32-bit Oracle database and a 64-bit operating system must use the 64-bit Oracle database. Before installing Oracle Database 11g R2, log in to the system as a root user and complete configurations as follows: Checking required software packages Before installing the Oracle database, make sure that you have installed required software packages on the operating system. If you are running Linux AS 5 or 6.1, use rpm qa to check all the installed software packages, and use rpm -q to check whether an rpm file is available. When a software package is not installed, copy the software package to your local device and use the rpm -i xxx.rpm command to install it. The software packages that are to be installed are: binutils compat-libstdc elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc gcc-c libaio-devel libaio libgcc libstdc libstdc++-devel make sysstat unixodbc unixodbc-devel libxext CAUTION: Make sure you install the following software packages: glibc (32bit), libaio (32bit), libgcc (32bit), and libstdc (32bit). 2

6 NOTE: On Linux AS 5, you can locate uninstalled software packages in the server directory of your installation disk and use the rpm ivh command to install them. On Linux AS 6.1, you can locate uninstalled software packages in the packages directory of your installation disk and use the rpm ivh command to install them. Checking the disk space Before installing the Oracle database, make sure that the hard disk drive where the home directory is located has at least 10 GB free space (The actual memory space requirements for the home directory depend on the managed devices and the number of performance monitoring instances) and the hard disk drive where the /tmp directory is located has at least 400 MB free space. To view available space on hard disk drives, use the following command: #df -k Adjusting kernel parameters To ensure the normal operation of the Oracle database, adjust the kernel parameters in the /etc/sysctl.conf directory using a text editor. If you are running Linux AS 5 or 6.1, make sure that the following kernel parameters take the same or larger values than those recommended: kernel.shmall= kernel.shmmax= kernel.shmmni=4096 kernel.sem= fs.file-max=65536 net.ipv4.ip_local_port_range= net.core.rmem_default= net.core.rmem_max= net.core.wmem_default= net.core.wmem_max= After you adjust the kernel parameters, use the /sbin/sysctl -p /etc/sysctl.conf command to make them take effect. Creating required user and groups user password You must create the oracle user, the oinstall group, and the dba group before installing Oracle because: Only the oracle user can install, start up, or shut down the Oracle database. The oinstall group user can install Oracle software The dba group user can manage the database. To create them, use these commands: Execute the following commands as the root user: groupadd oinstall groupadd dba useradd -g oinstall -G dba d /home/oracle m s /bin/bash oracle 3

7 Set the Oracle user password: passwd oracle Modifying the access right on the Oracle directory To enable the oracle user to execute the oracle database installation program, you need to modify the owner and access right of the directory where the Oracle database installation program is to be saved. # chown -R oracle:oinstall /home/oracle/ # chmod -R 775 /home/oracle/ Creating the Oracle base directory, directory owner and access right, directory owner, and access right Use these commands: mkdir -p /u01/app/ chown -R oracle:oinstall /u01/app/ chmod -R 775 /u01/app/ Modifying the profile file To make the environment variables of the Oracle database take effect automatically with the system loading, you need to modify the profile file as follows: #su - root #vi /etc/profile ORACLE_BASE=/u01/app/oracle ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1 ORACLE_SID=orc1 PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin LD_LIBRARY_PATH=$ORACLE_HOME/lib export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH where, The directories for ORACLE_BASE and ORACLE_HOME are flexibly set specific to the directory structure. ORACLE_SID is the Oracle database instance ID. Note that you must specify consistent ORACLE_SID in the subsequent installation procedure. Save the file after setting the language environment variable. Setting environment variables for the oracle user To ensure normal startup and operation of the Oracle database, you must configure the environment variables for the oracle user. For example, set the environment variables in file.bash_profile in the home directory: su - oracle vi.bash_profile 1. Open the file and set the language environment variable according to the language your system supports. 4

8 LANG=en_US.UTF-8 export LANG 2. Add the following line at the end of the text. umask Save the file, exit the system, and re-log in as the oracle user. exit su - oracle export DISPLAY=localhost:0.0 Checking the availability of environment variables Before installing the Oracle database, make sure that the environment variables have taken effect. Otherwise, you will fail to install the Oracle database. For more information, see "How to verify if the environment variables take effect? (page 63). Uploading the Oracle database to be installed Copy the Oracle installation package to the /home/oracle directory and decompress the package. If you use the installation disk, just follow the guide of the disk. Now, the preparation for installing the Oracle database is completed. Restart the operating system and then proceed with the Oracle installation. 5

9 3 Installing Oracle database 11g R2 After restarting the operating system, log in to the system as the oracle user, and perform the following command in the installation package directory: $./runinstaller.

52 5 Configuring a network service name CAUTION: If IMC servers deployed in distributed mode do not use the same database, do not configure network service names with the same name but different configurations for the IMC servers. When IMC servers are deployed in distributed mode or use a separate database server, you must configure a network service name for the IMC server to connect to its database server. The network service name includes the parameters, such as the name, host name, protocol, and database name. You can configure the network service name in the following ways: Execute the command as an Oracle user: Netca The window, shown in Figure 44 (page 49), for configuring an Oracle network service name appears. Figure 44 Welcome interface Select Local Net Service Name configuration and click Next. The Select an Operation window appears, as shown in Figure 45 (page 50). 49

This name is automatically added to the list for selecting a network service name when you install IMC. Click Next to advance to the service name screen, shown in Figure 54 (page 56). 55

59 Figure 54 Whether to configure another network service name If you want to configure another network service name, select Yes and click Next. If not, select No and click Next to access the configuration complete screen, shown in Figure 55 (page 56). Figure 55 Complete network service name configuration 56

60 Click Next to complete network service name configuration, shown in Figure 56 (page 57). Figure 56 Finish Click Finish. To illustrate the network service name configuration, take the following application scenarios for example: Scenario 1: If Server A (master IMC server), and Servers B and C (subordinate IMC servers) use local databases and have been configured with network service names TNSNAME_A for connecting to Server A, TNSNAME_B for connecting to Server B, and TNSNAME_C for connecting to Server C, respectively, you must configure the other two unavailable network service names for each server, for example, TNSNAME_B and TNSNAME_C for Server A. The configuration of the same network service name must be the same. Scenario 2: If Server A (master IMC server), and Servers B and C (subordinate IMC servers) use a separate database server DBServer_D and have been configured with a network service name TNSNAME_D for connecting to DBServer_D, Servers A, B, and C can use the network service name TNSNAME_D when you install IMC on them. NOTE: The network service names in the example are for illustration only. 57

61 6 Managing Oracle database 11g R2 To operate the database, you must log in to the system as oracle. Perform the commands in the subsequent sections as the oracle user unless otherwise specified. NOTE: The following operations apply only to the Oracle database server. Enabling the Oracle service manually 1. Enable the listener controller After rebooting the operating system, enable the listener controller using the following commands: $ cd $ORACLE_HOME/bin $./lsnrctl start To view the status of the listener controller named lsnrctl, use the following command: $./lsnrctl service 2. Enable the Oracle database After ensuring that you have successfully started up the listener controller, start up the Oracle database with the following commands: $ cd $ORACLE_HOME/bin $./sqlplus sys/ora123 as sysdba SQL>startup SQL>exit where, sys is the name of the administrator user of the Oracle database, and the user password is ora123. After running the preceding commands, you can successfully start up the Oracle database. Configuring Oracle database 11g R2 After installing the database server, make some configurations by changing the configuration file directly, or using the tool netmgr offered by Oracle. The following part of this section describes how to configure the Oracle database by using netmgr. Tool netmgr locates in the $ORACLE_HOME/bin/ directory. To enable netmgr, use the following commands: $ cd $ORACLE_HOME/bin/ $./netmgr Adding the database service for a listener On page Oracle Net Manager, select node LISTENER from the navigation tree. Select Database Services from the list box and then click Add Database. Specify the global database name, Oracle home directory, and the SID specified during the Oracle installation. Make sure the global database name and the SID are the same as those configured in the database identification page (see Figure 11 (page 16)). The detailed configurations are shown in Figure 57 (page 59). 58

62 Figure 57 Add the database service for a listener Setting the maximum number of Oracle processes and Oracle connection limit By default, the Oracle database allows 150 connections at most. When multiple IMC modules are deployed in centralized mode, or database errors occur on some IMC modules, you must set a proper maximum number of Oracle processes and a proper Oracle connection limit. For more information about the configuration procedure, see HP Intelligent Management Center Getting Started Guide. Shutting down the Oracle service manually To shut down the Oracle service, you need to shut down the Oracle database first, and then the listener controller. 1. Shut down the Oracle database Execute the following commands: $./sqlplus sys/ora123 as sysdba SQL>shutdown immediate SQL>exit where, sys is the name of the administrator user of the Oracle database, and the user password is ora Shut down the listener controller $ cd $ORACLE_HOME/bin $./lsnrctl stop Now, the Oracle service is shut down. 59

63 Configuring Oracle automatic startup To achieve Oracle automatic startup at the Linux operating system startup, register Oracle as the system service. 1. Copy the script file named oracled.tar.gz to the Linux operating system and then use the following command to unzip the file: tar -xzf oracled.tar.gz NOTE: The oracled.tar.gz file is in the manual/db/oracle directory of the IMC installation package. 2. Copy the unzipped file to the directory of /etc/rc.d/init.d/. (Execute the cp command as a root user.) cp oracled /etc/rc.d/init.d/ 3. Modify the attribute value of the file to 755 with the command chmod. (Execute the chmod command as a root user.) chmod R 755 oracled 4. Execute the service register command as a root user: chkconfig --add oracled 5. Edit the Oracle configuration file /etc/oratab, and change the last line: vi /etc/oratab Change the line: orcl:/u01/app/oracle/product/11.1.0/db_1:n to: orcl:/u01/app/oracle/product/11.1.0/db_1:y Save and quit the configuration. 6. You can use the commands of service oracled start and service oracled stop to start and stop Oracle services. Creating a database user Follow these steps to create a database user: 1. Log in to the Oracle database as the user SYS:./sqlplus sys/imc123 as sysdba sys is the username and IMC123 is the password. 2. Create a database user: NOTE: create user imc identified by imcpassword; imc is the username and imcpassword is the password. For IMC to correctly identify the password during installation, make sure that the password does not contain any of the following characters: ` ' \ "! ( ) & \\ $ < > / ^ \t 3. Grant the sysdba privilege to the user: grant sysdba to imc; 60

64 NOTE: Database users must be granted with the sysdba privilege for connecting to the database. Otherwise, deployment errors occur. Setting the character set for the Oracle client After installing the Oracle database ("Installing Oracle database 11g R2 (page 6)), you must set the NLS_LANG environment variable to comply with the client language environment. To make the NLS_LANG environment variable automatically take effect with the system loading, modify the /etc/profile file as follows: vi /etc/profile To set the language environment variables for client character set NLS_LANG, use these commands for different languages: English NLS_LANG=AMERICAN_AMERICA.WE8IS08859P15 export NLS_LANG Other languages Set a proper character set with the following format. NLS_LANG=LANGUAGE_NATIONAL.CHARACTERSET export NLS_LANG. TIP: You can set WE8ISO8859P15 for western European languages. Make sure the character set is set correctly, or garbled characters may appear. For more information about setting the client character set, see the Oracle Database Globalization Support Guide at 61

65 7 Installing IMC After completing all the configurations, reboot your operating system and log in to it as the root user. For information about how to install IMC, see IMC Installation Guide. TIP: After installing IMC, use the following commands to enable the IMC deployment monitoring agent. /opt/imc/deploy]#./dms.sh start /opt/imc/deploy]#./dma.sh 62

66 8 FAQ How to handle the case where the system displays that the space is not enough when creating the database instance? Check whether you have the file in the etc/sysctl.conf directory correctly configured. For more information, see "Adjusting kernel parameters" (page 3). How to handle garbled characters displayed on IMC? The garbled charactersmay be caused by the following reasons: Incorrect character set for the database Garbled characters may appear if you set the character set that is incompatible to IMC. For example, you set the English character set for Chinese IMC system. To solve this problem, reinstall the Oracle database, and select the correct character set. Incorrect character set for the clients Garbled characters may appear when NLS_LANG is not correctly set or modified during IMC operation. To solve this problem, correct the environment variable and restart the server and IMC. Incorrect environment variables for the server and the default installation of the Oracle database If you install the Oracle database by using the default mode, the Oracle is set with the default character set according to the LANG environment variables, which may not be correctly set. For example, if you use the default installation where LANG is C to install a database of Japanese character set, WE8ISO8859P1 will be set as the character set, so garbled characters appear. To solve this problem, follow the correct steps to re-install the Oracle database. You can follow the steps as in "Installing Oracle database 11g R2" (page 6) to install the Oracle database. TIP: For more information about setting the database and client character sets, see the Oracle Database Globalization Support Guide at How to verify if the environment variables take effect? Execute the command echo $variable name to verify if the configurations about the home directory, Oracle LIB, and Oracle instance take effect. For example: #echo $ORACLE_HOME /u01/app/oracle/product/11.1.0/db_1 #echo $LD_LIBRARY_PATH :/u01/app/oracle/product/11.1.0/db_1/lib #echo $ORACLE_SID orcl How can I update database passwords for IMC? The usernames and passwords used by the IMC modules are stored in cipher text in file \common\conf\ server-addr.xml in the installation path. You can use the./pwdmgr command to obtain passwords in clear text or update the latest passwords to the file. 63

67 Usually, a user can use the database management tool to change the database password of a certain IMC module. To ensure communication between IMC and the database, use the./pwdmgr command to update the corresponding password in file server-addr.xml. If IMC is deployed in distributed mode, you must update the password for every IMC server, as shown below. [root@daemon8829 imc]# cd deploy/ [root@daemon8829 imc]#./pwdmgr.sh modify config_db imc_config dbpasswd Change password successfully In the preceding commands, dbpasswd represents the latest database password of the imc_config user, config_db represents the database name, and represents the IP address of the database. To obtain the IP address and name of a Oracle database, view the settings of the corresponding user in file $IMCROOT/common/conf/server-addr.xml. If the database server connection is very slow, what can I do? Verify the DNS configuration: use the vi editing tool to check the DNS configuration information in the directory of /etc/resolv.conf: cd /etc vi resolv.conf serch rhel55x64.imc nameserver nameserver
