Server tuning parameters:
txngroupmax:- Specifies the number of files transferred as a group between commit points,default 4096. (server and client )
bufpoolsize:- The database buffer pool provides cache storage, which allows database pages to remain in memory for longer periods of time.(1/8 to 1/2 of RAM),default-32MB
maxsessions:- specifies the maximum number of simultaneous client sessions that can connect to the server. default 25
tcpnodelay :- allows the data packets less than MTU(max transmission unit)size to be sent immediately,(with out nagle algorithm)
tcpwindowsize:- The TCPWindowsize option specifies the amount of receive data in Kilobytes that can be in-transit at one time on a TCP/IP connection.default 63kb in win 64kb in aix
movebatchsize/movesizeth :-This option specifies the number of files that are to be moved and grouped together in a batch, within the same server transaction. The default value for MOVEBatchsize is 40 and the maximum value is 1000. The default value for MOVESizethresh is 500 and the maximum value is 2048.(server operation)
Client tuning parameters:
MEMORYEFFICIENTBACKUP :- TSM backs up one directory at a time, by default TSM backup all directories at a time which is memory intensive.
RESOURCEUTILIZATION :- Regulate the number of sessions that the client can communicate with the server during process.
tcpnodelay :- allows the data packets less than MTU(max transmission unit)size to be sent immediately,(with out nagle algorithm)
tcpwindowsize:- The TCPWindowsize option specifies the amount of receive data in Kilobytes that can be in-transit at one time on a TCP/IP connection.default 63kb in win 64kb in aix
txnbytelimit:- The txnbytelimit option specifies the number of kbs the client program buffers before it sends a transaction to the server. default 25600, range is 300 - 2 GB.
