AIX - out of memory error (any AIX experts on?)
713555Mar 12 2012 — edited Mar 13 2012Oracle EE 11.2, AIX 5.1
Been asked to look at a performance issue on AIX, I made some SGA changes and bounced the DB, however when i did i got out of memory processes trying to start the DB, 16gb of RAM on the box, SGA is 6gb the OS had nabbed a bit of the 6gb so i couldnt start the instance. Did a bit of reading and from what I can gather found AIX OS uses all memory available, I bounced the box to free it up, started the DB ok, I monitored the free RAM, after a while I could see the RAM at 0% idle again so if I needed to bounce the Db again, or if the instance crashed and tried to recover, Id have the same problem.
Anyone know AIX and comment on what this is behaviour is and how to resolve? Or a link to an explanation?
hoping theres a kernel "maxmem" setting or similar. google has let me down on this one.
