Kernel param for hyperfabric
Need some information about the kernel Param' clicreservedmem.
Have read the SAM help and need a practical setting in an oracle environment between two v2600's and 4 N class servers, using hyperfabric, any ideas ?

Try this link for some more information about the parameter.

Not sure about your particular circumstances though.

Re: Kernel param for hyperfabric
Hi,
clicreservedmem specifies how many bytes of system memory are to be reserved for I/O-mapping use by user processes in high-speed, distributed-server environments such as those used for running large database-processing programs.(defaults value 0)
The configurable parameter clicreservedmem provides a means for setting aside as much as 15/16 (approximately 93%) of total system memory for use by applications that perform large-volume, memory-mapped, network I/O. While this value could be as much as 512 Gbytes or even 1 Tbyte, it more commonly ranges from about 1 Gbyte to perhaps 64 Gbytes. Regardless of the value chosen within SAM, the actual memory reserved by the system cannot exceed 15/16 or total system memory.
I hope this helps
