Before We Start A Quick
Audience Survey
• How many of you have are on 11.0, 11i,
12?
• How many of you have started an R12
upgrade project?
• How many of you plan to upgrade to
R12 in the next 18 months?
• How many of you have already
migrated your DB to Linux?

Purge Junk Out of the DB
• Take a look at what is using the majority of
the space in your DB
select OWNER,
SEGMENT_NAME,
sum(BYTES) obj_size
from DBA_SEGMENTS
group by OWNER, SEGMENT_NAME
order by OBJ_SIZE desc;
• This query does not take into account index
space usage for an object

Account Generators had errored out long ago and
prevented processes from being purged. This was
fixed around 2006-03.
Oracle Support provided a script to close these
processes out so they could be purged.

18
Customization space hogs
• We dug through some of the custom objects
and found error and audit tables that were
not being purged.
XXCUST_F_CONCURRENT_REQUESTS
• This one is a history table of all concurrent
requests run, (maintained through on delete
triggers on concurrent request tables). We
summarized the historical data to save space.

19
Purge Summary
• Now is the time to start reviewing your
DB to purge out the junk.
• We removed about 30GB of junk. We
could not fully recover the space until
OATM had been implemented.
• Take a look at Lynne Paulus’s
presentation that occurred today in
session 4.14.
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
20
Get current on Tech Stack
• You should get the most recent AD pack
for patching.
• R12 does not support JInitator, so you
should start your migration now to the
Native SUN JRE. Your users will
probably be accessing your existing
instances and R12 from the same
desktops.

iSetup
•
•
•
•
This tool is a hidden gem in the OraApps.
Not the old iSetup, completely rewritten.
No additional license required.
Allows you to migrate setups and data
between OraApps Instances and Operating
Units.
• Allows you to create a snapshot of setups
then run difference reports to see “What has
changed all of the sudden…”.
• Mohan Iyer is giving a presentation on this
topic today in session 5.06.

OATM - Oracle Applications Tablespace Model
• How many of you have already
migrated to OATM?
• OATM FAQs, ML Note: 269293.1
• How to run OATM migration utility,
Note: 404954.1
• OATM Release 11i – Tablespace
Migration Utility, Note: 248857.1
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
23
OATM Benefits
• Reduces the total number of tablespaces (and
indirectly data files) to 12, classified by data
being stored.
• By consolidating the objects, space reorg’s of
tables/indexes are now possible.
• Reduces the total number of data files that a
checkpoint process needs to update.
• Currently optional, not mandatory at this
time. However, Oracle assumes OATM for
new module tablespaces.
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
24
OATM Migration Utility How Does It Work
• Generates scripts to create new
tablespaces, migrate actions, shrink
source tablespaces, purge empty
tablespace.
• Migration can be done incrementally
(tablespace by tablespace) – not
recommended. Or the whole system at
one time – recommended.
• You will need twice the disk space as
your existing instance.

OATM Uniform Extent Size
OATM creates the tablespaces with a
Uniform Extent Size.
Several notes on ML recommend an
extent size of 1MB.
Tables without any rows, will occupy
the minimum 1MB allocation for the first
extent.
In our instance this amounted to about
a 20GB overhead.
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
26
OATM Issues
• Apply patch 5467526, Note:389472.1, and
BUG 6454441, or ATG-H, RUP6.
• If the source tablespaces are locally managed
they will have space header data that will
prevent the files from being shrunk
completely Note:271866.1
• Shrink script have bugs and attempt to shrink
too fall and you will get:
ORA-03297: file contains used data beyond requested RESIZE value
• When completed you will probably need to
copy your datafiles back to the original disks.

27
OATM Issues
(cont)
• The Tablespace Migration Utility left some
LOB Segments in the Source Tablespaces and
did not report errors.
select tablespace_name, segment_type, COUNT(*)
from dba_segments
where tablespace_name not in

28
OATM Issues
(cont)
• You can find the object migration scripts
with the following query:
select * from FND_TS_MIG_CMDS where OBJECT_NAME = ‘xxxx‘;
• The fix we received from Oracle
Support was some manual edits to the
created scripts, then rerun them
manually.
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
29
OATM Issues
(cont)
• Double check the tablespaces are really
empty before dropping them. Oracle uses
the following syntax:
drop tablespace AK including contents and datafiles;
This forces the tablespace to be dropped
even if there is something in it.
select *
from DBA_TABLESPACES dt
where not exists (select 'Y'
from DBA_SEGMENTS ds
where ds.TABLESPACE_NAME = dt.TABLESPACE_NAME
and ds.SEGMENT_TYPE != 'SPACE HEADER' -- Note:271866.1
)
order by dt.TABLESPACE_NAME

31
OATM Issues
(cont)
• OATM only handles database objects that have space
allocated in DBA_SEGMENTS.
• GLOBAL TEMPORARY tables point to a tablespace at
time of creation.
• We have 70 of these that are pointing to the original
schema data tablespace, which has now been
dropped.
• The only way to find these was to write a script to do
a select count(*) from the object, which will throw:
ORA-00959: tablespace 'QPD' does not exist
• From within the OraApps this throws no error
message. You get a blank message window, or no
indication at all.
• Others have reported this issue on ML.

John Peters, JRPJR, Inc.
32
OATM Issues
(cont)
Two work arounds exist:
1. Recreate the missing tablespaces the
objects point to
2. Run the following scripts to retrieve
the DDL for the GLOBAL TEMPORARY
tables, drop them and recreate them.
set LONG 50000
select dbms_metadata.get_ddl(UPPER('TABLE') ,
UPPER('AD_PTCH_HST_EXE_COP_TMP'),UPPER('APPLSYS') )
from dual;

33
OATM Summary
The OATM process took about 24
hours of down time to complete.
We are still working the GLOBAL
TEMPORARY TABLE issue with Oracle
Support.

Linux DB Migration
•
Migrate from HP/UX 64bit, 10.1.0.4 to
Red Hat Linux 4 64bit, 10.2.0.3
•
Change database character set From

DB Migration Choices
1. Export/Import
– Export DB on HP/UX, Import DB on Linux
– Use data pump (and legacy exp/imp)
– Well documented:
•
•
10g Export/Import Process for Oracle Applications
Release 11i, ML Note: 331221.1
10g Release 2 Export/Import Process for Oracle
Applications Release 11i, ML Note: 362205.1
– Use R12 Rapid Install to create target
10.2.0.2 ORACLE_HOME, patch up to
10.2.0.3
01/17/08 NorCal OAUG Training

36
DB Migration Choices
(cont)
2. Transportable Tables Spaces
–
–
Copy datafiles from HP/UX
Run through RMAN to convert:
•
•
–
–
–
–
Endian format of data (byte ordering)
Character set
Create Linux DB without OATM tablespaces
“Attach” datafiles to Linux DB, (there are really
about 9 steps to complete this process)
Limited Oracle Documentation, none around
OraApps
Roger Schrag, Database Specialists, Inc. has a
great presentation on this topic:
http://www.dbspecialists.com/presentations.html#changing_platforms
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
37
What did we choose…
•
We spoke with Stephen Chan about
being a Beta customer for the
Transportable Tablespaces migration.
But this process looked like it would
be a fairly major investment of time to
develop and work out the kinks.
•
We chose to follow the documented
and proven Import/Export method.
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
38
Boy were we wrong…
•
Evidently, the export/import
processing with OraApps databases is
not as simple as following the
documented steps and using the
supplied parameter files.
•
We still have not succeeded at this
and are currently working issues with
Oracle Support.

Data Pump Issue 1
•
If a database user is assigned a
custom user profile that uses a custom
function it will error on the creation of
the user profile .
•
Workaround, manually create the
function and user profile in the
database prior to importing
01/17/08 NorCal OAUG Training
Day, Paper 5.14
John Peters, JRPJR, Inc.
41
Data Pump Issue 2
•
•
•
Data Pump can not handle XML Types.
These have to be migrated using the
legacy exp/imp process.
Why not just use the legacy exp/imp
process, it can not handle all of the
data types as well.
Workaround, run the import, find the
errors and then run the legacy
exp/imp process for those objects.

Data Pump Issue
•
(cont)
We are still working a variety of other issues
related to:
–
Data types not converted
–
Queue objects not converted and expected
before tables can be converted
……….
–
Please pre-create the object type in the target database and
then retry the datapump import with following parameter
TRANSFORM=oid:n
And we are trying to dig through the
thousands of errors to determine the real
precedence/root cause issues.

43
So where are we now…
•
For now we are upgrading the database to
10.2.0.3 on HP/UX and leaving the
character set as is.
•
And I thought we were taking the more
conservative approach…..
•
So my advice to everyone is to get these
tasks out of the way well in advance of your
R12 upgrade, so you will have time to work
the issues around these tasks.

HP/UX 10.2.0.3 Upgrade Warning
ML Note: 362203.1,
Oracle Applications Release 11i with
Oracle 10g Release 2 (10.2.0)
There is an error in Section 1, Step 12. The
three patches 5892355, 5871314, 5755471
must be applied for any 64bit OS. The
patches correct issues introduced on earlier
32bit to 64bit upgrades.

R12 Upgrade Steps
Same basic procedure as in the past
• Section 2, Preparing for Upgrade
(~33 steps)
•
Section 3, Upgrading to R12
•
Section 4, Post Upgrade
•
TUMS report is available to assist in
identifying steps that can be skipped.

R12 Upgrade Size
•
Oracle says to expect the following
size increases:
– 3% for 3 years of historical conversion
– 8.3% for 12 years of historical conversion
•
I am going to allow the database files
to autoextend up to a maxsize that
will allow for an approximate 10%
increase

R12 Upgrade Differences
•
No upgrade assistant spreadsheet:
upgasst.xls
•
This has been replaced by the ‘Maintenance
Wizard’. See ML Note 215527.1. This is
installed in a new RDBMS 10g with a 10g
iAS ORACLE_HOME on a UNIX or Linux
machine.
•
We are not using this at this time.

R12 Upgrade Differences
(cont.)
•
•
We don’t run AutoUpgrade.
We now use adpatch, and u*.drv file.
•
This is a special version of the AD

R12 Upgrade Differences
(cont.)
Upgrade by request
• You can defer historical data
conversions to a post upgrade step
• Concurrent requests will run in the
background to convert historical data
• You can decide to perform additional
historical data conversions any time in
the future
• Oracle uses this mechanism to convert
some default historical data
