5. Set <strong>the</strong> envir<strong>on</strong>ment variables MPSSCFGFILE and MPSSERRFILE. MPSSCFGFILE<br />
should point to <strong>the</strong> c<strong>on</strong>fig file that was created in Step 3. MPSS writes any errors<br />
during runtime to file.<br />
6. Preload MPSS interposing library mpss.so.1, and bring up Oracle server. It is<br />
recommended to put <strong>the</strong> MPSSCFGFILE, MPSSERRFILE, and LD_PRELOAD<br />
envir<strong>on</strong>ment variables in <strong>the</strong> Oracle startup script.<br />
With all <strong>the</strong> env variables menti<strong>on</strong>ed above, a typical startup script may look like<br />
<strong>the</strong> following:<br />
echo starting listener<br />
lsnrctl start<br />
echo preloading mpss.so.1 ..<br />
MPSSCFGFILE=/tmp/mpsscfg<br />
MPSSERRFILE=/tmp/mpsserr<br />
LD_PRELOAD=/usr/lib/mpss.so.1:$LD_PRELOAD<br />
export MPSSCFGFILE MPSSERRFILE LD_PRELOAD<br />
echo starting oracle server processes ..<br />
