Installing CAE components Db2® Query Monitor CAE components include the CAE agent, the CAE server, and the CAE browser client. Note: If you are migrating from a previous version of Db2 Query Monitor, see Upgrading. Installing the CAE agentThe CAE agent requires several installation and customization tasks. You must configure an MVS™ user ID to run the CAE agent, define CAE parameters, and customize the JCL needed to initiate the CAE agent. There are special considerations if you are using the fault-tolerant CAE server customization.Installing the CAE serverThe CAE server can be installed on either Windows® or USS. Additionally, the CAE server can function alone (single-server installation) or as part of a HAFT installation.Ensure High-Availability Fault-ToleranceIn Db2 Query Monitor, High-Availability Fault-Tolerance (HAFT) capability enables you to assign a CAE server as a backup for a primary CAE server . The backup CAE server ensures that the monitoring of queries continues if the primary CAE server fails. If the primary CAE server fails, the backup CAE server starts automatically and provides all the functionality that was provided by the primary CAE server.Creating and importing a hostname-based, self-signed certificate - WindowsFollow these steps to create and import a hostname-based, self-signed certificate for a CAE server on Windows®.Creating and importing a hostname-based, self-signed certificate - USSFollow these steps to create and import a hostname-based, self-signed certificate for a CAE server on USS.Logging in to the CAE browser client using multi-factor authenticationThe CAE browser client supports multi-factor authentication (MFA) login using your user ID, MFA token, and password.Exporting a certificate alias from different truststore types - USSFollow these steps to export a certificate alias from a different truststore type for a CAE Server on USS.Exporting a certificate alias from a JKS type trust store - WindowsFollow these steps to export a certificate alias from a JKS type trust store for a CAE Server on Windows®.Configuring SSL handshakes to use TLS 1.2The CAE server and the CAE agent perform the handshakes using the default SSL protocol, which can include SSL3.0, TLS1, TLS1.1, or TLS1.2.Defining secure connectionsIf you want to define a secure connection between Db2 Query Monitor and a network peer (such as a Db2® subsystem), Db2 Query Monitor must trust that peer.Parent topic: Installation and maintenance
