Modifying Installation Property Values

The response file contains parameter values (properties) that control installation and initial configuration.

Most Client Automation parameters have the prefix CA_ITRM, or CA_DSM, or ITRM_ or DSM_, or a prefix that indicates the component. Other parameters may be used by other CA products.

You can override the parameter values in the response file by using installdsm with the /R specification. This lets you modify the default installation behavior when running remote installations using the Infrastructure Deployment wizard or Software Delivery packages.

When you manually edit a response file, be careful with property values that are usually derived from other property values (mostly locations of directories and subdirectories). Do not hard-code a property value that was previously derived from another in order to not break any derivation relationship.

Example

SDLIBRARY (the location of the Software Delivery library) is by default derived from CA_DSM_CONFIGDATA (the location of Client Automation configuration data), which itself comes from CA_ITRM_BASEDIR (the main Client Automation location). These relationships are maintained in the supplied install.rsp response file. In a response file, if CA_DSM_CONFIGDATA is hard-coded as CA_DSM_CONFIGDATA=/data/CA/ConfigDataLocation and SDLIBRARY is hard-coded as SDLIBRARY=/data/CA/SDLibrary, the derivation relationships among CA_ITRM_BASEDIR, CA_DSM_CONFIGDATA, and SDLIBRARY are broken.

Note: Agent package-specific options are those installation parameters used during interactive deployment to specify the "additional UNIX install options" on the Agent Configuration page of the Infrastructure Deployment wizard. On that page, you can enter multiple install options, separated by spaces, to override existing options.
