Recommended Values for Network Tuning Parameters

Verify that the network tuning parameters are set to the values shown or higher values.

Table 3-6 Recommended Values for Network Tuning Parameters

Network Tuning Parameter	Recommended Value
ipqmaxlen	512
rfc1323	1
sb_max	4194304
tcp_recvspace	65536
tcp_sendspace	65536
udp_recvspace	655360 Note: The recommended value of this parameter is 10 times the value of the udp_sendspace parameter. The value must be less than the value of the sb_max parameter.
udp_sendspace	65536 Note: This value is suitable for a default database installation. For production databases, the minimum value for this parameter is 4 KB plus the value of the database DB_BLOCK_SIZE initialization parameter multiplied by the value of the DB_MULTIBLOCK_READ_COUNT initialization parameter:(DB_BLOCK_SIZE * DB_FILE_MULTIBLOCK_READ_COUNT) + 4 KB
