  23. Skipping Adpatch Workers • Select option 8 on adctrl menu to skip adpatch workers Jeff Slavitz, Computer Creations Inc.

  24. Hung Adpatch Workers • Most workers end in a few minutes. If one runs abnormally long it may be hung. • Confirm with ‘top’ • Use adctrl option 3 to shutdown all workers • Hung workers will not shutdown • kill -9 `ps –ef | grep adwork | cut –c 9-14` • You may also need to kill adpatch job Jeff Slavitz, Computer Creations Inc.

  25. Hung Adpatch Workers • Hung workers still show status of ‘Running’ • Use adctrl option 4 to fail all jobs • Then adctrl option 2 to restart all failed jobs • Restart adpatch Jeff Slavitz, Computer Creations Inc.

  26. Maintenance Pack Problems • Adpatch.log: • FAILED: file MTL_COPY_ORG_REPORT_TEMP.xdf • Adworker.log: Error in executing statement ALTER TABLE INV.MTL_COPY_ORG_REPORT_TEMP MODIFY ... ORA-00600: internal error code, arguments: [25012], [68], [0], [], [], [], [], [] • Work-around is to set "_disable_multiple_block_sizes" = true in the database init.ora Jeff Slavitz, Computer Creations Inc.

  36. Pre-Compiling JSPs • Compile JSPs using a regular expression $JTF_TOP/admin/scripts/ojspCompile.pl --compile -s \ '%' -log $LOGFILE --flush $JTF_TOP/admin/scripts/ojspCompile.pl --compile -s \ 'Apps%' -log $LOGFILE --flush • Compile an individual JSP $JTF_TOP/admin/scripts/ojspCompile.pl --compile -s \ 'jtflogin.jsp' -log $LOGFILE --flush Jeff Slavitz, Computer Creations Inc.

  37. Managing AutoConfig • AutoConfig re-writes: • Oracle 9i init.ora, tnsnames.ora, listener.ora, sqlnet.ora • Oracle 8.0.6 listener.ora, tnsnames.ora • Make your system AutoConfig independent using ifiles: • ifile last line in above files • ifile name defined in context file Jeff Slavitz, Computer Creations Inc.
