PSU 从11.2.0.3.0 -> 11.2.0.3.11 遇冲突解决全程

Oracle rdbms 打psu从11.2.0.3.0升级到11.2.0.3.11
参考patch :18522512
停应用，停监听与DB，将db的oracle_home下的OPatch目录加到环境变化PATH路径下，因为接下来要用opatch工具。
报错，说这个opatch工具太旧，要下载新的。
The OPatch version being used (11.2.0.1.7) doesn‘t meet the minimum version required by the patch(es). Please download latest OPatch from My Oracle Support.
下载了11.2.0.3.6的opatch工具，将内容覆盖Oracle_home的OPatch里面的内容，（做好备份）
一，首次尝试发现冲突

二、SR回复

此时我给MOS提了个SR，说了下情况。
Oracle工程师这么回复：
PSU patch 11.2.0.3.11 has conflicts
Here are the specific sub-patches of composite patch 18522512 that conflict with 12942119, 13004894
Sub-Patch 16619892 conflicts with 13004894
Sub-Patch 16902043 conflicts with 12942119 
大意是，我们的patch 18522512是复合patch ，里面有一些子Patch,这些子patch与我已打的patch12942119, 13004894有冲突。（一般patch号就是bug号）。什么是冲突呢？如果我打了个Patch修改了一个二进制文件，然后再打另外一个Patch又修改这个二进制文件，但是会把第一个patch的效果消除，那就是冲突。
Patch conflict occurs when patches try to modify same binaries. To resolve conflicts and get fixes of both conflicting patches, we need to apply merge patch.  
In case patch is conflicting PSU, then we say overlay patch instead of merge patch.  
In composite patch model, we need to look at which PSU conflicts with existing installed patch.  
In our case patch 13004894 patch conflicts with 11.2.0.3.7 PSU patch. So we develop overlay patch for 11.2.0.3.7 version,  
If you check patch 13004894, it would have released for other version as well, it means the patch conflicts with those PSU as well. 
一般来说，为了解决这种冲突，我们就要下载merge patch。merge patch能同时包含了两个冲突的patch的叠加效果。如果我们下载的是有冲突的PSU Patch，那么我们就用overlay patch的叫法来代替merge patch。意思是overlay patch也是叠加了冲突各方效果的psu patch包。对于psu patch这种复合的Patch包，我们需要知道这个包里面那个子patch与已经安装的patch产生冲突。在这个案例中，已经安装的patch 13004894与PSU PSU 11.2.0.3.7 与11.2.0.3.8有冲突。此时有同学要问了，我们要装的不是patch 11.2.0.3.11吗？怎么变成11.2.0.3.7了？

Dear Oracle team,
Thanks for your update.
11.2.0.3.11 is PSU version, not DB version. The last digit denotes at what PSU level the environment is.
Also PSU will not change the banner or binary version.
You can confirm this by querying
select * from v$version;
Reference:
Do Patchset Updates (PSU‘s) Change the Oracle Release Version/Fifth Digit? ( Doc ID 861152.1 )
PSU patches are composite. Suppose I have installed 11.2.0.3.4 PSU and applying 11.2.0.3.7 PSU, it will append fixes from 11.2.0.3.5 to 11.2.0.3.7
Old PSU will not be rolled back. In 10.2 and 11.1 old PSU will be rolled back while applying new PSU.
In 11.2 it has been improved. Time to rollback old PSU is saved.
More details at : Composite Patches for Oracle Products [Video] ( Doc ID 1376691.1 )
In our case the existing patches have conflict with Sub patches of PSU 11.2.0.3.11 while applying.
Those conflicting sub patches are 11.2.0.3.7 and 11.2.0.3.8. Existing patch has conflict with fixes of sub patches.
Hence we are applying overlay patches of those version.
In case the above update is not clear or if you have any doubts, kindly let me know. 

根据Oracle工程师的描述，11.2.0.3.11是一个PSU版本，而不是数据库版本。版本最后一位是代表该数据库PSU的版本。而我们的数据库是11.2.0.3，PSU不会改变它。参考（Doc ID 861152.1）
PSU patches是复合的，比如我要从11.2.0.3.4打到11.2.0.3.7，这个PSU会先从11.2.0.3.4打到11.2.0.3.5，再从11.2.0.3.5打到11.2.0.3.7。
在10.2与11.1中，打新的PSU时，老的PSU会回滚。但在11.2中就不会。参考(Doc ID 1376691.1).


Dear Oracle team,
Thanks for raising your queries.
Query: As I know,18522512 was 11.2.0.3.11.After I apply it after (3),Why I should down psu11.2.0.3.7 at(4)?Did the psu 11.2.0.3.11 not contain 11.2.0.3.7?
Ans: Yes, PSU 11.2.0.3.11 includes 11.2.0.3.7 PSU also.
In 4th step we are downloading patch 13004894 of 11.2.0.3.7 version.
While applying 11.2.0.3.11 PSU, it applies PSU patch 11.2.0.3.7 also which is not installed earlier.
Existing Patch 13004894 has conflict with 11.2.0.3.7 PSU, hence we are applying 13004894 of 11.2.0.3.7 version
Query: Apply PSU patch 18522512
Do you meadn I just put in
"cd 18522512
opatch apply"？Should I "startup" and "@catbundle.sql psu apply"?
We are applying patch only at binary level in 3rd step, i.e. opatch apply
Database start up and catbundle execution is covered in step 7
We can do this step along with opatch apply, but for applying overlay patch (step 4) again we have to shutdown the database.
To avoid that we apply all patches at binary first, then start the database to execute catbundle.sql 

11.2.0.3.11的PSU是包含11.2.0.3.7的PSU的。Apply 11.2.0.3.11的PSU，是会先APPLY 11.2.0.3.7版本的。但是，已经存在的patch 13004894跟这个11.2.0.3.7 PSU有冲突，因此我们需要安装13004894的11.2.0.3.7版本，这个PSU，是会包含11.2.0.3.7的PSU与13004894这个patch的协调版本。

三，实际操作
Thanks for contacting oracle support. 
PSU patch has conflict with existing installed patches. 
Merge patch is available for this conflict. You can follow below steps to apply patch 
1) Shutdown oracle services and then take backup of Oracle database, oracle home and central inventory 
2) Rollback conflicting patches 13004894,12942119 
opatch rollback -id <patch id> 
3) Apply PSU patch 18522512 
4) Download following overlay patches from Oracle support, 
https://updates.oracle.com/download/13004894.html 
choose platform as ‘Linux X86‘ and version as 11.2.0.3.7 
p13004894_112037_LINUX.zip 
https://updates.oracle.com/download/12942119.html 
choose platform as ‘Linux X86‘ and version as 11.2.0.3.8 
p12942119_112038_LINUX.zip 
5) Unzip the downloaded patches and apply. It will not have conflicts 
6) Start the database 
7) Perform PSU patch post Installation Instructions as specified in Patch Read me file 
Please let me know if you require more details/assistance on any steps 
We would like inform you about new MOS feature. 
A new Patch Conflict Checker feature is available in the latest release of MOS. This is accessible from the Patch Search results screen ("Analyze with OPatch" button) and allows you to analyze candidate patches for conflicts and request merge fixes a lot more easily and quickly at the time of patch download itself. This feature allows you to: 
1. Analyze patches for conflicts right at the time of patch download - All you need is your Opatch inventory. 
2. Locate already available replacement patches – So, you can download resolution patches immediately. 
3. Request a merge patch right there, if no replacement patches exist - You will not have to spend time logging a SR. 
For more information and a demonstration video, please see Note 1091294.1 - How to use the My Oracle Support Conflict Checker Tool. Should you need assistance get started, I am glad to set up a call/web conference to walk you through the steps.

（4）然后我们再下载13004894 这个与11.2.0.3.7 PSU能相融合的patch。再下载12942119这个能与11.2.0.3.8 PSU相融合的overlay Patch，并分别apply上。
（5）然后按照18522512 PSU的read me file里面的post Installation Instructions，进行catbundle。
sqlplus ‘/as sysdba‘
startup
@catbundle.sql psu apply

我们必须先做(3)，再做(4),(5)，也就是说先PSU18522512 后，再打overlay patch，而不能是先做overlay patch。
否则会报这样的错。

Recommended actions: This patch requires some other patches to be installed in the Oracle Home. OPatch cannot find those required patches in the Oracle Home.

而这个16619892，正是产生冲突的那个sub patch。
完成。
