Operating System Manipulation Elements
Contents
Operating System Manipulation Elements are used to execute various tasks on a host. They include the following:
- <os:verifyHost>: Verify that a particular hostname is defined in the DNS.
- <os:verifyGDA>: Verify that the GDA on a host is operational and reachable.
- <os:execShellCmd>: Execute a script or command on a host.
- <os:execSQL>: Execute SQL commands against a database.
- <os:setEnvVar>, <os:getEnvVar>, and <os:verifyEnvVar>: Set, get, and verify environment variables on a host.
- <os:installPackage>: Deploy an IP on a remote host.
