Process Manager server. Spread the database logs and table spaces across a RAID array to<br />
distribute disk use. Tune the SCA.SYSTEM..BUS database and the BPEDB as<br />
follows:<br />
► db2 update db cfg for sysdb using logbufsz 512 logfilsiz 8000 logprimary 20<br />
logsecond 20 auto_runstats off<br />
