upgrade steps• Will not install JDK 1.4.2

Rapid Install Tech Stack• New tech stack code installed to new path• To retain existing tech stack path install it twice.

For example:– Original 8.0.6 and iAS ORACLE_HOME at

/ora01/PROD/…– Install new tech stack to /ora01/PRODupg– Use new OUI to remove Oracle Home at /ora01/PROD– Install new tech stack again to /ora01/PROD– Use OUI to remove tech stack at /ora01/PRODupg

Rapid Install Tech Stack• From stage area: rapidwiz –techstack• For details, Rapid Install manual chapter 5

Upgrading JDK and JInitiator• Oracle recommends using JDK 1.4.2 with

11.5.10• Download JDK 1.4.2 for your operating

system, Metalink note 130091.1• Upgrade to JInitiator 1.3.1 using Metalink

note 124606.1 • Requires users to download new JInitiator

Tips for Applying Maintenance Pack

• Correct errors found by pre-upgrade validation scripts

• Turn off custom triggers and applications before applying patch 3140000

• Save time and apply custom AutoConfig changes after upgrade is complete

• Work in parallel with Oracle Support

Tips for Applying Maintenance Pack

• Skip adpatch workers that fail for applications you are not using

• Open a tar to confirm no cross-application issues

• Manually re-run script that failed when problem resolved

Skipping Adpatch Workers• Select option 8 on adctrl menu to skip

adpatch workers

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

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

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

Maintenance Pack Problems• Adpatch.log:

FAILED: file aftcm049.sql

• Adworker.log:ORA-20000: Oracle Error Mkr4= -904

ORA-00904: "RULESET_NAME": invalid identifier • Problem caused by Advanced Queue corruption

that occurs when upgrading to 9.2.0.x from 8.1.7.x. Follow note 231074.1 and run the three patch scripts provided.

Maintenance Pack Problems• For errors uploading .ldt files, upload

manually using adodfcmp:adodfcmp userid=jtf/xxx touser=apps/xxx priv_schema=system/xxx changedb=yes mode=tables odffile=xxx.odf logfile=xxx

• Specifying ‘changedb=no’ will show changes without making them

Maintenance Mode• New feature with 11.5.10/AD.I• Adpatch requires maintenance mode• Use adadmin option 5

Maintenance Mode

Maintenance Mode• Be sure to disable Maintenance Mode or

users cannot login to Financials

Adpatch Hotpatch• If you want to apply a patch without

enabling maintenance mode and disabling user access:adpatch options=hotpatch

• The Maintenance Utilities manual indicates this causes severe performance degradation

Helpful Tips• Transfer setups between instances using

FNDLOAD, Metalink note 274667.1 – Concurrent program definitions– Responsibilities– Menus– Profile Options– Value Sets– And more!

Pre-Compiling JSPs• Java Server Pages (JSP) compiled when

user first accesses a page• May result in noticeable delay• Perceived as ‘performance’ problem• Pre-compile all or first used JSPs

Pre-Compiling JSPs• Compiled JSPs normally stored on web tier

at $OA_HTML/_pages/_oa__html• Unix command ‘ls –ltr’ shows:

– Pages used– Order pages are compiled

• Use ojspCompile.sh as explained in Metalink note 215268.1

Pre-Compiling JSPs• Compile JSPs using a regular expression$JTF_TOP/admin/scripts/ojspCompile.pl --compile -s \ 'OA%' -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

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

OATM• Convert database to Oracle Application

Tablespace Model. See Metalink note 248857.1

– Reduces over 300 datafiles to 12– Saves a lot of disk space!– Easier to manage– Migrate tablespaces incrementally– Large tablespaces can take a LONG time to

migrate

Summary• Spend the time to plan your upgrade before

starting it• Long for the days of \ Row Erase?• Keep careful notes of what you’ve done• Use the tools Oracle provides to make your

system easier to upgrade and maintain
