Hi All,

We are deploying Oracle Calendar 10g on redhat AS 4. I get error message 
when I run ocasctl -stats -on

Accessing "OCASStats"Error (0x50101): The shared memory block does not 
exist.

I also get another error message in another log file as follows:

Could not open/create cache table (0x51208)


When I check /proc/mminfo, I found that there is no MemShared part

[root at oct1 ~]# cat /proc/meminfo
MemTotal:      4150196 kB
MemFree:       3905332 kB
Buffers:         15692 kB
Cached:         122108 kB
SwapCached:          0 kB

However, there is a MemShared part on redhat AS 3
cat /proc/meminfo

        total:    used:    free:  shared: buffers:  cached:
Mem:  4217614336 4049330176 168284160   376832 291663872 2934161408

SwapCached:          0 kB

We have checked all systems with redhat AS 4 in our environment. There are 
no MemShared parts on Redhat AS 4


What cause this problem? We have update all the latest patches.


Thanks,
