i have to add the parameters
em/initial_size_MB= PM
em/max_size = 100000
when i entered the value of max_size = 100000
value is not permitted default is 64000
and one more thing is
rdisp/ROLL_MAXFS = [BE] * 100
rdisp/ROLL_SHM = [BE[ * 100
please can you give me the details of value for this its very urgent
Thanks very much
how much space and database version are you using for memory base on the memory you have to tune your parameters you can refer sap notes 327494/203924

em/initial_size_MB = <PHYS_MEMSIZE> is the piece of EM memory, reserved in page file. I would not recommend to set it to lower value as your RAM, because if EM is exhausted next EM chunk allocated is equal 1GB -> might lead to page file fragmentation.
em/max_size = 100000
this value must not be larger than "RAM+Pagefile size" as this is limitation for EM, that could be allocated in page file

rdisp/ROLL_MAXFS = [BE] * 100
rdisp/ROLL_SHM = [BE[ * 100
you can look in ST02 and ST02-History at "Max usage" for these parameters and reduce/increase them correspondingly

If it´s "very urgent" open an OSS call.
Buffers always depend on implementation (number of users, number of active modules, number of customizing transports getting transported, Unicode/non-unicode)... Tuning them is an iterative process, where you use a value, let the system run for some days and check them again.
