Hi all! For some education reason a try to start Oracle with SGA=1,4Gb on RELENG_7_0 I put many "trace" code-lines into linuxolator sources and find what Oracle after successful call shmget() try to create files on /dev/shm, aka /dev/shm/ora_orcl_$SHMIDT But don't set O_CREAT flag for open(), only specify O_LARGEFILE flag So, at linux_open() the path (/dev/shm) not converted to linuxolator path. (I mount tmpfs on /compat/linux/dev/shm mountpoint whith options rw,size=2Gb) I find what O_LARGEFILE is only Linux spec flag for open() and I look for correct (aka BSD) way to to change behavior of linux_open() Have fun! chd ps. sorry for my english (
