Oracle Solaris on x86-64 (64-bit) kernel parameter tuning to avoid WARNING: EINVAL creating segment

edited Aug 19, 2010 8:26PM in Oracle Solaris System Administration (MOSC) 3 commentsAnswered
RDBMS 10.2.0.4 on Oracle Solaris on x86-64 (64-bit) 10.

Was trying  to increase SGA from  4GB to 5GB (we have 20GB phy mem) through Solaris Projects.  However, when we bounced the  RAC instance we got  the following warning MESSAGE upon the  instance startup (after ASM startup)  :
WARNING :EINVAL creating segment of size 0x000000014000300
fix shm parameters in  /etc/system  or equivalent  (we also set  SGA_MAX_SIZE and SGA_TARGET to   5GB)

These are the values of Oracle kernel parameters. Please let me know if anything is wrong (which prevents us from increasing SGA) or anything not required in general:

set shmsys:shminfo_shmmax=5368709120

Howdy, Stranger!
