shmat() error on 2.6 sparc2 running 7.3.4

Hi,

I'm trying to install oracle 7.3.4 on a sparc2 running solaris 2.6 with 64 Mbytes RAM. The error message ORA-07307 says it's unable to attach sga, and to verify that the attach address is valid.

How do I determine what the attach address is, and whether or not it's valid? Does anyone know of any good resources that explain how oracle calls shmget and shmat?

Thanks in advance for any assistance,

pfm

Here is my /etc/system changes, as suggested by oracle:

	 set shmsys:shminfo_shmmax=8388608
	 set shmsys:shminfo_shmmin=1
	 set shmsys:shminfo_shmmni=100
	 set shmsys:shminfo_shmseg=10
	 set semsys:seminfo_semmns=200
	 set semsys:seminfo_semmni=70
	 set semsys:seminfo_semmsl=50

And output from tstshm

	(oracle)>>tstshm
	Number of segments gotten by shmget() = 50
	Number of segments attached by shmat() = 10
	Segments attach at lower addresses
	Maximum size segments are not attached contiguously!
	  Segment separation = -2162688 bytes
	Default shared memory address = 0xef3e0000
	Lowest shared memory address  = 0xdfe70000
	Highest shared memory address = 0xef3e0000
	Total shared memory range     = 259457024
	Total shared memory attached  = 20971520
	Largest single segment size   =  2097152
	Segment boundaries (SHMLBA)   =     4096 (0x1000)
