Recommended Values for Network Tuning Parameters

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

Table 3-5 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
