System Monitoring Plug-in Installation Guide for IBM DB2 Database

Release 6 (3.1.1.0.0)

E11113-01

December 2007

This document provides a brief description about the Oracle System Monitoring Plug-In for IBM DB2 Database, details on the versions the plug-in supports, prerequisites for installing the plug-in, and step-by-step instructions on how to download, install, verify, and validate the plug-in.

Description

The Oracle System Monitoring Plug-in for IBM DB2 Database extends Oracle Enterprise Manager Grid Control to add support for managing IBM DB2 Database instances. By deploying the plug-in in your Grid Control environment, you gain the following management features:

Platforms Supported

The plug-in supports monitoring of IBM DB2 instances on Linux, Unix, and Microsoft Windows.

Versions Supported

This plug-in supports the following versions of products:

Prerequisites

The following prerequisites must be met before you can use the plug-in:

Setting Up the JDBC Driver

The JDBC driver is available from IBM, and consists of the following files that the Agent must be able to access:

To set up the IBM DB2 Universal Type 4 JDBC driver, do the following:

  1. Create a jdbcdriver directory under agent/sysman/ and place the .jar files listed above in that directory.

  2. Add the location of each individual driver .jar file to the classpath.lst file under the $ORACLE_HOME/sysman/config directory.

  3. If the Agent is installed on a system that is part of an OS cluster, then you need to edit the classpath.lst file under the $ORACLE_HOME/<node_name>/sysman/config directory, where node_name is the name of the system where the Agent is installed.

    If the classpath.lst file does not exist, create the file. For example, the classpath.lst file in a UNIX environment might appear as shown in the following example:

    /home/usera/agent/sysman/jdbcdriver/ibm/db2jcc.jar

    /home/usera/agent/sysman/jdbcdriver/ibm/db2jcc_javax.jar

    /home/usera/agent/sysman/jdbcdriver/ibm/db2jcc_license_cu.jar

Using a Suitable Operating System User and Assigning Authorities and Privileges

The System Monitoring Plug-In for IBM DB2 accesses the table functions used in IBM DB2. For the plug-in to have access to the table functions, you have to use a suitable operating system user and assign this new user to a user group. The operating ssytem user must have at least the minimum privileges. In addition, you have to assign the correct authority levels to this user.

Note:

IBM DB2 users must be operating system users. IBM DB2 cannot have its own database users because it relies on the host operating system for security.

If you do not have an operating system user already created, first, create one on the host where IBM DB2 is running. Then, follow these steps to assign this user to a new or existing UserGroup.

  1. Open the IBM DB2 Control Center.

  2. From the tree view, select the database or database alias to which you want to connect.

  3. Connect as an admin user.

  4. From the tree view, select User and Group Objects.

  5. From the right pane, select the already-created operating system user.

  6. From the Authorities panel, select Connect to Database.

  7. To verify the applied changes, try connecting to the database.

Note:

These steps can also be performed from command line using IBM DB2 SQL.

Also, assign authorities and privileges for the operating system UserGroup. The authorities supported with IBM DB2 are SYSADM, SYSCTRL, SYSMAINT, DBADM, and LOAD. The SYSADM, SYSCTRL, and SYSMAINT authorities cannot be granted using the GRANT SQL statement. These special authorities can only be set from the database manager configuration file. DBADM privilege can only be granted by user at SYSADM authorization level.

SYSMON authority level is required to monitor IBM DB2. This level is required to access the table functions, such as SYSPROC.SNAPSHOT_DATABASE, which are used in IBM DB2.

Follow these steps to set SYSMON authority level to your UserGroup:

  1. At the db2=> prompt, run the following commands:

    db2=> update dbm cfg using sysmon_group USERGROUP
    db2 => db2stop
    db2 => db2start
    
  2. To check whether the changes are effective, run the following command:

    db2 => get dbm cfg
    

    The following will be the output of the previous command:

    Database Manager Configuration
    Node type = Enterprise Server Edition with local and remote clients
    .....
       SYSADM group name     (SYSADM_GROUP)   =
       SYSCTRL group name    (SYSCTRL_GROUP)  =
       SYSMAINT group name   (SYSMAINT_GROUP) = 
       SYSMON group name     (SYSMON_GROUP)   = USERGROUP
    ......
    

Note:

To understand how authorities and privileges are implemented in IBM DB2, access the IBM Web site.

Deploying the Plug-in

After you ensure that the prerequisites are met, follow these steps to deploy the plug-in:

  1. Download the IBM DB2 Database Plug-in archive to your desktop or computer on which the browser is launched. You can download the archive from the Oracle Technology Network (OTN).

  2. Log in to Enterprise Manager Grid Control as a Super Administrator.

  3. Click the Setup link in the upper right corner of the Grid Control Home page, then click the Management Plug-ins link on the left side of the Setup page.

  4. Click Import.

  5. Click Browse and select the plug-in archive.

  6. Click List Archive.

  7. Select the plug-in and click OK.

  8. Verify that you have set preferred credentials on all Agents where you want to deploy the plug-in.

  9. In the Management Plug-ins page, click the icon in the Deploy column for the DB2 Database plug-in. The Deploy Management Plug-in wizard appears.

  10. Click Add Agents, then select one or more Agents to which you want to deploy the plug-in. The wizard reappears and displays the Agent you selected.

  11. Click Next, then click Finish.

    If you see an error message stating that the preferred credential is not set up, go to the Preferences page and add the preferred credentials for the Agent target type.

Configuring IBM DB2 for Health Indicator Metrics and Database Monitoring Metrics

The following sections explain the postinstallation configuration steps you need to perform on IBM DB2.

Configurations Required for Health Indicator Metrics

The health indicators for instance and database objects are enabled and disabled using the database manager configuration parameter -- HEALTH_MON. Then, the table functions -- HEALTH_TBS_HI, HEALTH_DB_HI, and HEALTH_DBM_HI get populated. These functions are used by the plug-in to show the alerts triggered based on the thresholds of health indicators.

Note:

Enabling these settings may result in some overheads, such as CPU and memory. Therefore, follow these steps only if you want to view the Health Indicator metrics.

To enable or disable the HEALTH_MON by CLP (Command Line Processor), run the following command:

db2==> update dbm cfg using HEALTH_MON [on;off]

To check if your changes are effective, run the following command:

db2==> get dbm cfg

The following is the output:

.....
.....
.....
Monitor health of instance and databases (HEALTH_MON) = ON
.....
..........

For more information, access the IBM Web ste.

Configurations Required for Avoiding Metric Collection Errors for Database Monitoring Metrics

To avoid metric collection errors for for the "Database Monitoring" metrics, make a call to the GET_DBSIZE_INFO package so that the STMG_DBSIZE_INFO table gets created and populated with the required data.

The GET_DBSIZE_INFO procedure calculates the database size and maximum capacity. The calculated values are returned as procedure output parameters and cached in the SYSTOOLS.STMG_DBSIZE_INFO table. The procedure caches these values because the calculations are costly.

The SYSTOOLS.STMG_DBSIZE_INFO table is created automatically the first time the procedure runs. If there are values cached in the SYSTOOLS.STMG_DBSIZE_INFO table and they are current enough, as determined by the snapshot-timestamp and refresh-window values, then these cached values are returned.

If the cached values are not current enough, new cached values are calculated, inserted into the SYSTOOLS.STMG_DBSIZE_INFO table and returned, and the snapshot-timestamp value is updated. The last parameter in the GET_DBSIZE_INFO call is refresh window.

Default value refresh window (time difference between successive calls) is 30 minutes. If your database is growing at a faster rate, then you can set a lower value.

To make a call to GET_DBSIZE_INFO by CLP (Command Line Processor), run the following command:

db2==>CALL GET_DBSIZE_INFO(?, ?, ?, -1)

In this case, the refresh window is 30 minutes.

For more information, access the BIM Web site.

Adding Instances for Monitoring

After successfully deploying the plug-in, follow these steps to add the plug-in target to Grid Control for central monitoring and management:

  1. From the Agent home page where the plug-in was deployed, select the IBM DB2 Database target type from the Add drop-down list, then click Go. The Add IBM DB2 Database page appears.

  2. Provide the following information for the properties:

    • Name — Name for the plug-in

    • JDBC URL — URL name for the IBM DB2 JDBC Driver connectivity.

      For example,

      jdbc:db2://<server>:<port>/<database>

      The JDBC URL argument represents a data source. Parameter definitions are as follows:

      • jdbc:db2 — Indicates that the connection is to a DB2 UDB server.

      • server — Domain name or IP address of the database server.

      • port — TCP/IP server port number assigned to the database server, which is an integer between 0 and 65535.

      • database — Database alias, which refers to the DB2 database catalog entry on the DB2 client.

        The database name is determined by the DB2 server being used:

        DB2 for Linux, Unix, and Windows Servers — If the connection is to DB2 UDB for Linux, UNIX, and Windows servers, database is the database name defined during installation.

    • JDBC Driver — (Optional) Name of the DB2 Universal JDBC Driver.

      For example,

      com.ibm.db2.jcc.DB2Driver

    • Username — Valid user name for the database.

      For more information, see Using a Suitable Operating System User and Assigning Authorities and Privileges.

    • Password — Password for the user.

  3. Click Test Connection to make sure the parameters you entered are correct.

  4. Reenter the encrypted parameters from step 2 if the connection test was successful, then click OK.
