With AT&T Sys V/386 Release 3.2.2, the maximum shared memory allowed out-of-the-box is 512K (as defined in the "mtune" file). Our Turbo and OnLine engines can make use of much larger amounts if available. Are there any hidden dangers to boosting the mtune constraints to allow larger values to be set in stune? Right now, I'm running with a SHMMAX of 8 MB (8388608) and a SHMALL of 8192, and it appears to work OK. This is on a 6386E/33 with 24 MB and an unlimited user license. (I also boosted SEMMNS to 120, if that matters). Are there any potential dangers here? The doc "recommends against" exceeding the regular mtune limits, but they don't say why or give guidelines for SHM* parameters in large memory configurations. -- Alan S.
