Configuring the Agent

You can configure the Informix agent using the following methods:

• By using VCS Cluster Manager (the VCS graphical user interface) to edit a resource group template for the Informix agent. See Configuring the Agent Using Cluster Manager (Java Console), or,
• By directly editing the sample main.cf file supplied with the Informix agent (see Configuring Informix Agent by Editing the Configuration Files). This method requires that VCS be stopped and restarted before the configuration takes effect.

Configuring the Agent Using Cluster Manager (Java Console)

A template for the Informix resource groups is automatically installed when you install the Informix enterprise agent. Using the VCS Cluster Manager, you can view the template, which displays the Informix service group, its resources and their attributes. You can dynamically modify the attribute values as necessary for your configuration.

Importing the InformixTypes.cf File

To use the Informix template, import the InformixTypes.cf file to the VCS engine by using Cluster Manager:

1. Start Cluster Manager.
2. Click on the File menu and select Import Types.
3. In the Import Types dialog box, select the file:
     /etc/VRTSvcs/conf/sample_Informix/InformixTypes.cf
4. Import the types file for Informix.
5. Save the configuration.

At this point, the Informix types have been imported to the VCS engine. The Informix agent can be configured without interrupting or stopping VCS.

For detailed information about using the VCS Cluster Manager, refer to the chapter on administering VCS from Cluster Manager (Java Console or Web Console) in the VERITAS Cluster Server User's Guide.

Creating a New Service Group Using Cluster Manager (Java Console)

To create a new service group, import the InformixTypes.cf file and then download the InformixGroup template by starting the Service Group Configuration Wizard from the Cluster Manager.

Creating an Informix Service Group

1. Launch the cluster configuration wizard in one of the following ways:
   • Select Tools>Configuration wizard from the Cluster Explorer menu.
   • If no service groups exist on the system, the Cluster Explorer prompts you to launch the Cluster Configuration wizard. Click Yes when prompted.

   The Loading Templates Information window appears and launches the wizard.

2. Read the Welcome screen and click Next.
3. Specify the name of the service group and the target systems on which it is to be configured.
   1. Enter the name of the service group.
   2. In the Available Systems box, select the systems in the cluster on which you want to configure the service group.
   3. Click the right arrow to move the selected systems to the Systems for Service Group table. To remove a system from a table, select the system and click the left arrow.
   4. Indicate whether you want the service group to become online automatically when VCS starts, by clicking on the Startup checkbox beside the system name. Specify the order in which you want the systems to fail over by assigning priorities to the cluster systems.
   5. Click Next.
4. In the Would you like the service group to be based on a template? window, click Next.
5. In the Select Templates dialog box, select the Informix template (InformixGroup) on which to base the service group.

   If the names that you specified for some resources for the new service group are already in use, a window opens notifying you of this. This window also includes a list of alternative names. You can select an alternative name, or modify the name. Click Next after resolving the name clashes.

6. Click Next to create the service group based on the selected template. A window opens indicating that the commands are being sent to the add group, its resources, and the attributes and dependencies specified in the template. A progress indicator displays the percentage of the commands fired. The actual commands are displayed at the top of the indicator.
7. Click Next when prompted that the service group has been successfully created.
8. A window opens listing the service group's resources and their associated attributes. Click Finish to accept the default values and complete the configuration.

   You can modify the default values of the resources according to your specific configuration requirements. For details see the following section.

Editing the Resource attributes

This section describes the procedure to edit attributes using the Cluster Manager. For
a list of attributes that must be configured for the Informix service group, refer to attribute definitions for the Informix resource type on .

1. Select a resource from the list on the left. Its attributes appear in the right pane.
2. Select the attribute to be modified.
3. Click the edit icon in the Edit column.
4. Enter attribute values in the Edit Attribute window. To modify the scope of the attributes, select either Global or Local option. For non-scalar values, use the + or the X buttons to add or delete values, respectively.
5. Click OK.
6. Repeat the procedure for each resource and its attributes and click Finish. Edit the attributes for all the resources according to your configuration.
7. Follow the wizard instructions to complete the configuration. Click Finish to quit the wizard.
