SELFTUNETXNSIZE

Specifies whether Tivoli Storage Manager can automatically change the values of the TXNGROUPMAX, MOVEBATCHSIZE, and MOVESIZETHRESH server options. Tivoli Storage Manager sets the TXNGROUPMAX option to optimize client-server throughput and sets the MOVEBATCHSIZE and MOVESIZETHRESH options to their maximum to optimize server throughput. The default is NO.

Note:
Although the values of TXNGROUPMAX, MOVEBATCHSIZE, and MOVESIZETHRESH may be changed, the settings in the server options file are not changed. Issuing a QUERY OPTION command displays only what is set in the server options file.
