Hello,
I have Oracle 8.1.6.2 on Linux.
The host has 2 GB RAM,as you can see:
>free

             total       used       free     shared    buffers     cached
Mem:       2009368    1967188      42180    1888584     312100     788552
-/+ buffers/cache:     866536    1142832
Swap:      1052248         76    1052172

(oracle_at_i138)
I have 512MB of memory allocated to db_block_buffers and when I tried to increase this value even slightly (to 612MB) the instance didn't start, saying that it can't allocate shared memory. Why? There should be enough of it on this host.
TIA
