We were having problems with a very low directory cache hit rate even though we had a large cache. I didn't mention it in my note, but we have another system in the cluster which had identical hardware, a smaller directory cache, but a much higher hit rate. Everyone was puzzled. The solution was simple, allocate more pool (I can hear all of the RSX guys saying, "of course, allocate more pool..."). Turns out that when the ACP goes to allocate the caches and finds that it can't get enough memory, it reverts to a small default and tries to allocate that. Yes, we did use AUTOGEN to set things up. Don't worry DEC, the SPR is in the mail... ---------------- Marty Sasaki uucp: harvard!sasaki Strategic Information arpa: sasaki@harvard.harvard.edu 80 Blanchard Road bitnet: sasaki@harvunxh Burlington, MA 01803 phone: 617-273-5500
