Sets match control parameters for a shareable image and specifies the match algorithm. This option allows you to control whether executable images that link with a shareable image must be relinked each time the shareable image is updated and relinked. Format GSMATCH=keyword,major-id,minor-id GSMATCH=EQUAL,link-time-derived-major-id,link-time-derived-minor-id (default)

keyword Identifies the match algorithm used by the image activator. Specify one of the following keywords: Keyword Meaning EQUAL Directs the image activator to allow the image to map to the referenced shareable image when one condition is met: o the major and minor ID for the shareable image, as saved at link time in the image file, are equal to the IDs found in the actual shareable image file at activation time. LEQUAL Directs the image activator to allow the image to map to the referenced shareable image when two conditions are met: o the major ID for the shareable image, as saved at link time in the image file, is equal to the major ID found in the actual shareable image file at activation time o the minor ID for the shareable image, as saved at link time in the image file, is less than or equal to the minor ID found in the actual shareable image file at activation time. ALWAYS Directs the image activator to unconditionally allow the image to map to the referenced shareable image: o regardless of the values of the major and minor ID for the shareable image, as saved at link time in the image file, and the values of the IDs found in the actual shareable image file at activation time. Note that you must still specify values for the major ID and minor ID parameters to satisfy the requirements of the option syntax. major-id Specifies the major identification number. minor-id Specifies the minor identification number. When a shareable image is created without specifying a GSMATCH= option, the linker by default creates one. It sets the EQUAL match control and uses portions of the image creation time, as a binary value, for the major and minor IDs. In general this is sufficient to set a unique value for the IDs each time the shareable image is linked. On I64, the linker uses bits 40 through 54 of the binary time value for the major ID and bits 8 through 39 for the minor ID. On Alpha and VAX, the linker uses bits 32 through 46 of the binary time value for the major ID and bits 16 through 31 for the minor ID.
