Murali, This is an odd error message. Oracle creates a
pool of memory in the SGA for sending messages globally
in the cluster. The amount of memory that is allocated is
128 bytes * MAX (lm_ress, db_block_buffers, 10000), so
you get at least 1,280,000 bytes of memory for this
messaging. My guess would be that the defaults are being
set and the memory needed to create message buffers is
not available. I am surprised that you are not getting
some other messages like dynamic allocation of locks or
dynamic allocation of resources. This could be a Compaq
thing as well. I am running OPS(8.1.7) on NT and Solaris
and I have not seen this error. You could attempt to set
lm_ress to a value greater than 10000. The problem you
will run into is that Oracle now dynamically sets the
defaults for lm_ress and lm_locks in 8.1.7 and they have
not documented how to override the values. In 8.1.7 you
have to specify lm_ress=(minvalue,maxvalue), this is the
same for lm_locks as well. Oracle doesn't use the
minvalue but does set the parameter to the maxvalue. So
if you set lm_ress=(10000,25000) then lm_ress actually
gets 25000. Doing this may help with the warning.
