PurgeImageSource (system param)

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP

Controls whether image data can be purged to the %tmp% device whilst processing an image when virtual memory is getting low. In systems with a disk, it often makes sense to point the %tmp% device at a disk and to leave this parameter at its default value of true . Setting a value of false in this case makes it more likely that the RIP will run out of virtual memory during the processing of a job. However, in a diskless environment setting the value to false makes sense because the %tmp% device may well point to a RAM disk within the same memory pool as the RIP. Purging memory to the RAM disk simply moves the data from one place to another within the same memory pool and therefore does not help to avoid running out of virtual memory and will degrade performance.

Default: true .
