I'm setting up FreeBSD 4.1 to run Oracle for Linux. The Oracle docs say the SHMMAX should be set to 0.5 * (physical memory), which in my case would be 0.5 * 131072 = 65536, if I understand correctly. From reading the tutorials and mailing list archives regarding Oracle on FreeBSD, I see that the SHMMAX setting is deprecated and the setting SHMMAXPGS should be used instead. So, here is where I'm stuck. If SHMMAX == (SHMMAXPGS * PAGE_SIZE + 1), as per LINT, then SHMMAXPGS == SHMMAX / PAGE_SIZE + 1, or 65536 / 8192 + 1, which is 9. This is far different than the numbers given in the handbook or in the tutorial at http://www.lf.net/lf/pi/oracle/install-linux-oracle-on-freebsd, which are set at 10000 and 4097 respectively. Has my logic gone wrong here? Joseph To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
