John Peters, JRPJR, Inc. 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 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 Pauluss 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.

01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 21 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 22 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 reorgs 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 25 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. 01/17/08 NorCal OAUG Training

Day, Paper 5.14 John Peters, JRPJR, Inc. 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 ('APPS_TS_ARCHIVE', 'APPS_TS_INTERFACE', 'APPS_TS_MEDIA', 'APPS_TS_NOLOGGING', 'APPS_TS_QUEUES', 'APPS_TS_SEED', 'APPS_TS_SUMMARY',

'APPS_TS_TOOLS', 'APPS_TS_TX_DATA', 'APPS_TS_TX_IDX', 'SYSTEM') and segment_type != 'SPACE HEADER' -- Note:271866.1 group by tablespace_name, segment_type; 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 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 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 30 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; 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 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; 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 34 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 WE8ISO8859P1 To AL32UTF8 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 35

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 Day, Paper 5.14 John Peters, JRPJR, Inc. 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_platfor ms 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 39 Patches, Patches, Patches 4872830, Per Note 331221.1, Section 1, Step 2 5873146, Per Note 331221.1, Section 1, Step

3 5753621, Per ML 362203.1 5064356, Note:5064356.8 patch was unavailable so we ended up working around this by changing the NFS mounts parameters 3897122 and 4352110, on the Source DB Update system data in SYSTEM_PRIVILEGE_MAP using an SQL statement per Oracle Support 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 40 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc.

42 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 44 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. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 45 R12 Upgrade What we all want to know more about. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 46

TUMS report is available to assist in identifying steps that can be skipped. 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 48 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 01/17/08 NorCal OAUG Training Day, Paper 5.14

01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc. 50 R12 Upgrade Differences (cont.) We dont run AutoUpgrade. We now use adpatch, and u*.drv file. This is a special version of the AD utilities (R12.AD-A) that must be applied via patch just before you begin the upgrade on the older OraApps version. 01/17/08 NorCal OAUG Training Day, Paper 5.14

John Peters, JRPJR, Inc. 51 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 01/17/08 NorCal OAUG Training Day, Paper 5.14 John Peters, JRPJR, Inc.
