Hi Bert,
Yes there are !
If you TSM server is d�dicated, depending on how much RAM you have, you can
adjust the ram used by TSM to ALL minus the network buffers you want.
Here is a sample for one of my small TSM Servers (256 MB RAM, 1 Eth 100, 1
Eth 10)
% no -a
thewall = 8192 => 4096 * Nb network interfaces (but < 1/4
RAM) (Eth,TR,X25,FDDI)
sb_max = 1048576
tcp_sendspace = 655360
tcp_recvspace = 655360
rfc1323 = 1 => TCP Extensions for High Performance
(buffers > 65535)
% lsattr -El sys0
maxmbuf 32768 Maximum Kbytes of real memory allowed for MBUFS True
=> maxmbuf must be the same as
% lsattr -El ent1
tx_que_size 512 TRANSMIT queue size True
rx_que_size 128 RECEIVE queue size True
media_speed 100_Full_Duplex Media Speed True
==> you can change the hardware buffers of your network card
To see avail values, just type
% lsattr -Rl ent1 -a tx_que_size
When you adjust, yous TSM BUFPOOLSIZE, check that you have enough RAM. If
bufpoolsize increases your swap files, you need more RAM. To see you much
RAM,
your TSM server uses, do the following :
% svmon -P <tsm_id>
Pid Command Inuse Pin Pgspace
11638 dsmserv.42 55741 16 37293
Pid: 11638
Command: dsmserv.42
Inuse * 4096 = used memory, if > than real RAM, you will have poor perf.
Good luck
Herve
