However, you can set timeouts for the SQL call to return, should the JB be too slow to exchange platters or if the required platter is out of the JB and on the shelf (requiring manual loading). A message to sent to the console and you hope that an operator is looking at the screen at that point! I'm not sure whether Online/optical supports CD-ROMS, I thought it was only WORM and MO disks but I could be mistaken, >Also I would like to know about alternatives to Plexus to control the >jukebox or optical disk. Here's some mail I got from a ex-Plexan who makes an alternative ... "Consistency Point Technologies have a optical file system, OptiLink. It is similar to Plexus Storage Manager and works with Informix's OnLine/Optical. We also have a 'C' API that allows you to Optical Storage enable existing applications. OptiLink supports all the major hardware vendors, the major UNIX vendors and NT. Pricing is slot base and is very competitive with existing product offerings.
