CPU Patch Project

This is the project i have been assigned need suggestion, queris to check CPU,(qualified DBs), Road map...etc, any other suggestion
PHASE I
1) Identify all the existing oracle versions across the board for the preparation of cpu patch ===> you can logon to many servers and find out or contact the individual DBA to do it for you or ask India team to help you.
2) Identify the oracle versions qualified for cpu patch on non-prod env for the preparation of cpu patch
3) Identify the oracle versions need to be upgraded for applying the cpu patch on non-prod env for the preparation of cpu patch
4) Identify the oracle versions qualified for cpu patch on prod env for the preparation of cpu patch
5) Identify the oracle versions need to be upgraded for applying the cpu patch on prod env for the preparation of cpu patch
PHASE II
6)Check with the customer if we can test/install the cpu patch on the lab server & upgrade/cpu patch if we get the approval
7) Work with the customer to get an outage on non-prod qualified databases and schedule the change window for cpu patch
8) Work with the customer to get an outage on prod qualified databases and schedule the change window for cpu patch
9) Work with the customer to upgrade the oracle versions if the application is compatible with the upgraded version of oracle
10) If the customer provides acceptance for the upgrade, the databases will be upgraded and the cpu patch will be installed by the DBAs with in a maintenance window.

See also the Oracle On Demand Best Practices Critical Patch Update white paper which is a good reference document on CPU patching project.
However it seems that since July 2007, CPU patch will now also include many bug fixing for non security issues which might change application behaviour and raise the question about application testing needed. For example,
4711525 - PARSING BITMAPPED PLANS IS 3X TIMES MORE COSTLY
4712638 - ORA-00600 [15160] ORA-7445[KKOGBRO]
4722645 - ORA-7445 ON COMPLEX QUERY
There are 319 fixes in 6079588 (10.2.0.2 for Linux) but only 19 security fixes according to http://www.oracle.com/technology/deploy/security/critical-patch-updates/cpujul2007.html#AppendixA.

CPU patch July 2010 on Oracle 11.1.0.7 database

Hi,
I want to install the July2010 CPU patch (9655014) on a 11.1.0.7 database which was initially created with version 11.1.0.6.
The README file of the patch states the following about recompiling views:
3.2.2.2 Recompiling Views in the Database
You may skip this section if you have recompiled views for this database during the installation of a previous CPU or if the database was created with Release 11.1.0.6 or later.
So I assumed that I do not need to recompile the views but a little further in the README file I read:
If you want to check whether view recompilation has already been performed for the database, execute the following statement.
SELECT * FROM registry$history where ID = '6452863';
If the view recompilation has been performed, this statement returns one or more rows. If the view recompilation has not been performed, this statement returns no rows.
When I execute the select it returns no rows. So this is confusing. Should I perform a view recompilation or not?
And when I execute recompile_precheck_jan2008cpu.sql (strange name for a July 2010 CPU) it says:
SQL> @recompile_precheck_jan2008cpu.sql
Running precheck.sql...
Number of views to be recompiled :1969
Number of objects to be recompiled :4019
Please follow the README.txt instructions for running viewrecomp.sql
PL/SQL procedure successfully completed.
thanks in advance.
regards,
Ivan

Short answer: you dont need to run view_recompile_jan2008cpu.sql
Long answer:
>
SELECT * FROM registry$history where ID = '6452863';
If the view recompilation has been performed, this statement returns one or more rows. If the view recompilation has not been performed, this statement returns no rows.
When I execute the select it returns no rows. So this is confusing. Should I perform a view recompilation or not?
>
You will only get an entry in registry$history if you had a database that you had actually run the view_recompile_jan2008cpu.sql script which inserts a row into the table at the end of the script:
view_recompile_jan2008cpu.sql
Rem =======================================================================
Rem Insert values for patch into registry.
Rem =======================================================================
INSERT INTO registry$history (action_time, action, id, comments)
        values ( SYSTIMESTAMP, 'CPU', &&PATCH_NUMBER, '&&PATCH_DESC' );
COMMIT; In your case, you will get no entries in the table BUT you do not have to run the view recompilation so long as the database was created using a patched Oracle home of a release where Oracle says the view recompilation is not required.
>
SQL> @recompile_precheck_jan2008cpu.sql
Running precheck.sql...
Number of views to be recompiled :1969
>
This script has a very simple logic that just generates count of views and dependant objects that would need recompilation. The selection criteria does not include actually checking whether you actually need to apply the view recompilation script.
You can test this yourself:
Case#1: Run the recompile_precheck_jan2008cpu.sql on a database where you have applied the view recompilation script. You will find the count shows a non-zero value.
SQL> col action_time format a32
SQL> col version format a15
SQL> col version format a15
SQL> select action_time, version, id from registry$history where ID=6452863;
ACTION_TIME                      VERSION                 ID
24-JUL-10 12.52.15.390000 PM                        6452863
SQL> @recompile_precheck_jan2008cpu.sql
Running precheck.sql...
Number of views to be recompiled :1637
Number of objects to be recompiled :3487
Please follow the README.txt instructions for running viewrecomp.sql
PL/SQL procedure successfully completed.Case#2: Create a new database using a version that does not require the view recompilation patch. Run the recompile_precheck_jan2008cpu.sql. You will find the view count shows a non-zero value even though you do not need to recompile the views as mentioned in the Oracle patch notes.

CPU Patch for SOA BPEL -10.1.3.5 and B2B -10.1.2.0.4

We are in DOD -GOVT US marine corps.. WE are on 10.1.3.3.1 .. There is no CPU Patches for 10.1.3.3.1 nor
for 10.1.2.03-B2B
open issues/questions:
Open Issues:
1. What is Oracle's recommendation about upgrading 10.1.3.5 vs 10.1.3.4 (CPU Patch support length). Also CPU Patch support policy for BAM 10.1.3.3.1 and B2B 10.1.2.3.
2. Any MLRs to apply after upgrading SOA/BPEL/WSM/BAM/B2B 10.1.3.5 ?
3. Interoperability of OWSM 10.1.3.4, BAM 10.1.3.3.1, B2B 10.1.2.3 and SOA/BPEL 10.1.3.5. Can they co-exist or must they(one or more) be in same release level?

OAS 10.1.3.5 on Windows 64 bit, NO CPU patch for April?

After reading the CPU Advisory for April CPU 2011, it appears that for OAS 10.1.3.5 on Windows 64 bit, that there is NO CPU patch for April? It only shows a patch for Windows 32 bit. They do not mean that the 32 bit patch should also be applied on 64 bit Windows o/s having OAS 10.1.3.5? I just want to make sure I skip this CPU since I have 64 bit o/s.
I ask because the list of bugs fixed in the README for the 32 bit patch list 32 bit bug fixes , and then 64 bit bug fixes.
Edited by: user12152237 on May 9, 2011 6:17 PM

Somu, please check a topic 3 lines below. No, there's not a separate 64-bit installer, but there's a work-around albeit not supported by oracle.

FTPing .zip CPU patch files...

Hi
I have downloaded a .zip file for Oracle CPU Patch and wants to move it to UINX server. After connecting the UNIX server, beofre I say "put <filename>"...do I have to say "binary"?
Your answer will be highly appreciated.
Thanks & Regards
Ahmed.

Hello,
Besides the previous answer, generally (if you click on the patch detail) you have the size of the zip file in bytes.
For instance:
Size 1.1G (1123325074 bytes) So, once you have sent the zip file on the Unix server, you can check if it's size is correct.
Hope this help.
Best regards,
Jean-Valentin

Download of January CPU Patch, the filename is somewhat cryptic

I've tried to download the january cpu patch for three different o/s and when I click the download button, the file name looks right (i.e. p9952279_10105_SOLARIS64.zip), but when I click save the file name changes to a variation of letters and number (i.e. CAER8HUF.zip).

Determinating CPU patch version in 8.1.7.4. database

How can I determinate currently installed CPU patch version in oracle 8.1.7.4 database (HP True64UNIX). (some alternativ for "opatch inventory" from higher versions of databases)

Hi,
It's a great question about 8i...

Oracle 10g CPU patch

Oracle 10g on Windows server 2003. I need to do CPU patch. I follow the patch instructions, but I have some questions:
1. back up %oracle_home% directory. Is this just to copy whole directory to different disk?
2. clean shutdown all Oracle services: I know this includes db, listener, db control, anything else?
3. The Db has ASP application on the top. How to shutdown application? what components should I look at?
Webserver that uses Oracle client in the mid-tier?
4. What does ODBC application mean?
5.What does this mean? "make sure no applications are using the driver sqora32.dll"
6.What does "Oracle Instant Client" mean? Is this regular Oracle client tool installed on application server? I guess not.
Appreciate any help.

My question: Is this just to copy to different disk OR you have other way to do it?It is a suggestion that will allow you to recover. In some cases (non-production) I will skip this step.
In production, I will ask the Backup team to make an extra backup of the entire ORACLE_HOME so they can do a quick restore if I mess up. (Then I'll be extra careful not to mess up.)
And yes, if you are comfortable that a disk copy will be sufficient to do a complete restore, then that should be OK as well.

2.clean shutdown all Oracle services: I know this includes db, listener, db control, anything else?
I don't have ASM or ClusterwareThe you probably don't need to worry about it.
If you have any other Oracle stuff (BI Suite, SOA Suite, etc) that tries to log on to the database, these must be made aware of the outage - usually by shutting them down. Even if they are not on the same server.
>
3.What does this mean? "make sure no applications are using the driver sqora32.dll"
My question is where and how can I find this DDL?
Are you seriously saying you do not have access to an OS file-search tool?
At least one copy is in ORACLE_HOME/bin
>
4. What does "Oracle Instant Client" mean? Is this regular Oracle client tool installed on application server? I guess not.
My question is that is this tool to get installed on Oracle server or application server? My vendor installed the Oracle server for us, how do I know if this tool got installed or not?It is a completely separate download. It is usually installed at the client, not on the server. However, since you have a vendor install, you may want to discuss this with the vendor.
The big challenge with Instant Client is that it is not an 'install' . It is just an unzip into an arbitrary directory, and does not get recorded in the registry. So almost impossible to find without the SysAdmin's install notes.

Need info on CPU patches

Hi,
Could someone please explain me what CPU patches are. Is it some security patch?
Is it mandatory to apply these patches every quarter. And if we apply, will there be any performance related issues?
Thanks!

The application of the Oracle quarterly patch CPU set is optional. If your testing requirements are too high to make application of multiple patches per year impractical then you might just apply every other or even one of the patch sets per year. The CPU patches are cumulative so if you apply the most recent you have all the prior patches.
The above is providing you do not need a specific fix provided by one of the patch sets. You current version of Oracle and when you plan to upgrade may also be a factor in determining if you need/want to apply a specific CPU.

Did you find a solution to this issue? We are having a similar issue trying to deploy a Paypal IPN on OAS 10.1.2.3. The IPN messages coming from Paypal appear to be attempting an SSLv2 handshake. In our case SSLv2 is disabled due to our security requirements so the connection is killed by our App Server. We have found that manually sending the IPN messages works correctly.

Differences between PSUs and traditional CPU patches

Hi, this is Eric Maurice, Director Oracle Software Security Assurance. In the past, I have been getting a number of questions about the differences between the Patch Set Updates (PSUs) and traditional Critical Patch Update (CPU) patches.
On August 11th at 11:00AM Pacific / 2:00PM Eastern, the Independent Oracle User Group (IOUG) will host a webcast on Database Server security patching featuring two speakers from Oracle: Bruce Lowenthal, Director for Security Alerts, and Lois Price, Director for Product Lifecycle Services.
The purpose of this technical webcast is to discuss the various aspects of the Critical Patch Update (CPU) program, which are specific to Oracle Database Server. The speakers will spend a significant portion of the webcast discussing the differences between the Patch Set Update (PSU) and traditional CPU patches. An overview of the CPU program will also be provided, and ample time will be set aside for a Q&A session at the end of the presentation.
