Oracle 11g 新特性 -- Online Patching （Hot Patching 热补丁）说明

一．官网说明

MOS 的文档：RDBMSOnline Patching Aka Hot Patching [ID 761111.1] 有说明。这里取部分内容。

A regular RDBMSpatch is comprised of one or more object (.o) files and/or libraries (.afiles). Installing a regular patch requires shuttingdown the RDBMS instance, re-linking the oracle binary, and restarting theinstance; uninstalling a regular patch requires the same steps.

On the otherhand, an online patch is a special kind of patch that can be applied to a live,running RDBMS instance. An online patch contains a single shared library; installing an online patch does not require shutting downthe instance or relinking the oracle binary. An online patch can beinstalled/un-installed using Opatch (which uses oradebug commands toinstall/uninstall the patch).

1.1 How does Online Patching differ than traditionalpatches?

--online patching 与传统patch 的区别：

1. Online patches are applied and removedfrom a running instance where traditional patches require the instances to beshutdown.
2. Online patches utilize the oradebug interface toinstall and enable the patches where traditional diagnostic patches arelinked into the "oracle" binary.

--online patch 使用oradebug 接口来install和 enable patches。
3. Online patches do not require the "oracle" binary to be relinkedwhere traditional diagnostic patches do.
4. There is additional memory consumption and processstart time penalty for online patches.

--online patch 需要消耗一些额外的内存和时间。

1.2 How Does the Online PatchMechanism Work ?

--online Patch 的工作机制

We firstconstruct a shared library that contains the relevant fixes and/or diagnostics.When we need to install the online patch, we use oradebug commands to tell eachoracle process to perform several steps:

--首先构造一个包含相关的fix或者diagnostics的shared library，当安装online patch时，使用oradebug 命令来通知每个oracle 进程按如下步骤进行切换：

1. Map the shared library into theiraddress space.
2. For each modified function in the patch, change theoriginal function in the text segment so that it performs a jump/branch to the"new" version in the shared library.
3. If the patched code references static variables inthe binary, have these references resolve to the right memory location.
4. If the patched code references static functions inthe binary, have these references resolve to the right memory location.

Uninstalling an online patch is the undoing of step 2: weremove the jumps/branches from the text segment and restore the originalinstructions.

1.3 Required Support from the OS

OnlinePatching requires two major items of support from an OS:

--Online Patching 主要需要OS 2方面的支持：

1. Ability to change protections on text segment pages andmodify these pages - For example, Linux x86 32-bit and Solaris 64-bitprovide COW (copy-on-write) semantics for text pages: once a text page is modifiedby a process, that process now has a private copy of that page. Note that theimplementation currently assumes COW-like semantics: it is not designed to workon an OS which provides the ability for one process to modify a text page suchthat this change affects all other processes which are sharing the sameimage/binary.

2. Support for shared libraries or DLLs - Online patchingrequires the ability to "bundle" modified code into a shared libraryor DLL such that it can be dynamically loaded by oracle processes. Ideally, theoracle binary should also be linked in such a way that shared libraries canrefer to global functions and variables in the binary; for example, on Linux,the oracle binary is linked with the "--export-dynamic" flag. (Currently,the mkpatch utility assumes that nothing special needs to be done when apatch's shared library has references to global functions/variables in thebinary; it is assumed that the dynamic loader will handle this when the sharedlibrary is loaded.)

Currently SupportedPlatforms：

Online patching iscurrently supported on these platforms/systems:

01 HP-UX Itanium.............................. ( requries OS Patch HPUX 11iv3 (11.31) + [March2008 Quality Pack + PHKL_38038] )
02 IBM AIX on POWER Systems (64-bit) .. ( requires AIX 6.1 + TL-02 +SP-01 onwards )
03 IBM: Linux on POWER Systems
04 IBM: Linux on System z
05 Linux x86
06 Linux x86-64
07 Microsoft Windows x86 (32-bit) .......... ( requires Opatch toolversion 11.2.0.1.1 )
08 Microsoft Windows x86-64 (64-bit)
09 Oracle Solaris on SPARC (64-bit) ........ ( requires SunOS kernelpatch 137111-04 )
10 Oracle Solaris on x86-64 (64-bit) ........ ( requires kernel patch137112-04 )
11 HP-PARISC Notsupported
12 Windows/Itanium Not supported

1.4 OPatch - How are Online Patches Installed?

OPatch is the recommended (Oracle-supplied)tool that customers are supposed to use in order to apply or rollback patches.It maintains an inventory of patches, and ensures that two conflicting patchesare not simultaneously installed. OPatch was recently modified to supportonline patches, which means that it can apply/rollback online patches, as wellas detect conflicts between any two kinds of patches. As such, it is notnecessary for customers to execute the "oradebug patch" commands;OPatch does this.

--Oracle 推荐使用OPatch来安装。

All OPatch versions after 11.1.0.6 areOnline Patch aware.

The syntax to install an Online Patch is:

opatch apply online-connectString <SID>:<USERNAME>:<PASSWORD>:<NODE>

example:

$ opatch apply online -connectStringdb11202:sys:oracle -invPtrLoc/u01/app/oracle/product/11.2.0/dbhome_1/oraInst.loc

For RAC you can list allof the instances:

opatch apply online -connectString<SID>:<USERNAME>:<PASSWORD>:<NODE1>,<SID2>:<USERNAME>:<PASSWORD>:<NODE2>,...

The USERNAME and PASSWORD are those of a user that hasSYSDBA privileges. The USERNAME and PASSWORD can be left blank if the OSuser applying the patch has the SYSDBA privilege. Also the NODE is optional ifthe patch is being applied locally.

--USERNAME 和PASSWORD 需要SYSDBA 权限，或者留空，使用OS 认证。

1.5 How to disable or remove the fix from some SIDs

If you want disable or remove the fix forsome SIDs, You need to use the opatch util DisableOnlinePatch as following :

opatch utilDisableOnlinePatch -connectString<SID>:<USERNAME>:<PASSWORD>:<NODE> -ph Patch location

-ph 参数：
Specify the valid patch directory area. This utility will disable the givenpatch in the database instances.

for details, see:

opatch util DisableOnlinePatch -help

example:

opatch util DisableOnlinePatch -connectString OP1:sys:manager: -ph/home/oracle/10188727/online

(...)
Invoking utility "disableonlinepatch"
Disabling and removing online patch 'bug10188727.pch', on database 'OP2'

OPatch succeeded.

Note:
the presence of "/online" at the end of "valid patch directoryarea"

1.6 How do I know which patches are eligible to be appliedonline?

--如何判断patch 是online patch
If the fix is online patchable there will be directory online that is created.Also the readme will contain the information regarding this, always read thereadme file when applying a patch for any new information or informationrelated to that specific patch.

--如果是online patch，那么patch里会包含一个目录，叫online，并且也可以查看readme 文件。

Example:

$ cd <PATCH_TOP>/10188727
$ ls
etc/ files/ online/ README.txt
$ tree online
online
|-- [embde 4096] etc
| |-- [embde 4096] config
| | |-- [embde 290] actions.xml
| | |-- [embde 22] deploy.xml
| | `-- [embde 1326] inventory.xml
| `-- [embde 4096] xml
| |-- [embde 5376] GenericActions.xml
| `-- [embde 1663] ShiphomeDirectoryStructure.xml
`-- [embde 4096] files
`-- [embde 4096] hpatch
`-- [embde 177874] bug10188727.pch

The better way to check if a patch is online is to use the following command

--最好的方法是使用如下命令来检查是否是online patch：

$ cd <PATCH_TOP>/10188727
$ opatch query -all online

1.7 How are Online Patches rollback'ed?

--如何回滚onlinePatch：

Using "opatch" you can rollbackthe patch：

--使用如下命令：

opatch rollback -id <patchID> -connectString<SID>:<USERNAME>:<PASSWORD>:<NODE1>,<SID2>:<USERNAME>:<PASSWORD>:<NODE2>,...

The USERNAME and PASSWORD are those of a user that has SYSDBA privileges. TheUSERNAME and PASSWORD can be left blank if the OS user applying the patch hasthe SYSDBA privilege. Also the NODE is optional if the patch is being appliedlocally.

Using opatch does not remove the patch, it simply disables it (rolls it back)and removes the patch entry from the inventory. This behavior may change in thefuture.

--使用opatch命令不会remove 这个patch，它是简单的disable online patch并从inventory中移除patch entry。在以后的版本中可能会改变这种方式。

Example:

$ opatch rollback -id10188727 -connectString db11202:sys:oracle -invPtrLoc/u01/app/oracle/product/11.2.0/dbhome_1/oraInst.loc

Others not recommended way are:

--还有2种不推荐的方法：

1. Using "oradebug" to disablethe patch

SQL> oradebugpatch disable <patch_id>.pch

2. Shutting theinstance down and removing the orapatch*.cfg file. After stopping theinstance do the following:

cd $ORACLE_HOME/hpatch
rm orapatch$ORACLE_SID.cfg

Removing the orapatch*.cfg removes all of the online patches currentlyinstalled for the instance.

Note:
its recommended to rollback only when the online patch is not required for anydatabases in the same ORACLE_HOME.
In case you have done a rollback the online patch can be disabled only by -phoption for the other SID's (see How to disable or remove the fix from someSIDs)

二．Online Patching 说明

说明：该部分内容摘自OCP 050 教材。

在Oracle 11g中提出了online patch(也叫hot patch)的特性；Hot patching允许我们在实例始终在线的情况下安装，启用或禁用一个修复补丁（fix）或者诊断补丁（diagnostic patches）。

使用热补丁可以安装、启用和禁用正在运行的活动Oracle 实例上的bug 修复或诊断补丁程序。使用热补丁是可在应用热补丁程序时避免停机的建议解决方案。Oracle 提供了使用opatch 命令行实用程序对任何Oracle 数据库进行热补丁的功能。如果代码的更改范围和复杂性都较小（例如，诊断补丁程序或小型bug 修复），则可提供热补丁程序。

2.1 安装热补丁程序

（1）应用热补丁程序不需要关闭实例、重新链接Oracle二进制文件或重新启动实例。

（2） OPatch 可用于安装或卸载热补丁程序。

（3） OPatch 可以检测两个热补丁程序之间以及热补丁程序与常规补丁程序之间的冲突。

可以使用以下命令来确定某个补丁程序是否为热补丁程序：

opatch query -is_online_patch <patchlocation> or

opatch query <patch location> -all

注：

打过补丁的代码将作为动态/共享库提供，该库随后会被每个Oracle 进程映射至内存中。

（关于热补丁的机制可以参考1.2 节的内容。）

2.2 热补丁的优点

(1) 无停机时间，不中断业务

(2) 安装和卸载速度极快

(3) 与OPatch 集成：

检测冲突

在补丁程序清单中列出

在RAC 环境中工作

(4) 虽然不改变磁盘上的Oracle二进制文件，但热补丁程序在实例关闭和启动时都保持有效。

2.3 常规补丁和热补丁

常规补丁基本上要求关闭数据库实例。

热补丁不需要任何停机时间。在安装热补丁时，应用程序可以继续运行。

同样的，无需停机便可卸载已安装的热补丁程序。

常规补丁和热补丁的对比，如下图：

2.4 热补丁注意事项

（1）可能不是所有平台上都有热补丁程序。当前在以下平台上有热补丁程序：

– Linux x86

– Linux x86-64

– Solaris SPARC64

--这个具体可以参考：1.3 小节。

（2）要消耗一些额外的内存。

– 确切的内存数取决于：

— 补丁程序的大小

— 当前运行的Oracle 进程数

– 最小内存数：每个Oracle 进程大约占一个OS 页面

如：一个操作系统(OS) 页面在Linux x86 上一般为4 KB，在和Solaris SPARC64 上为8 KB。

在平均大约一千个Oracle 进程同时运行的情况下，这意味着一个小型的热补丁程序大约额外占用4 MB 内存。

（3）在每个Oracle 进程安装或卸载热补丁程序之前，可能会有一段极短的延迟（几秒）。

（4）并非所有bug 修复和诊断补丁程序都可用作热补丁程序。

极大部分诊断补丁程序可作为热补丁程序提供。对于bug 修复，则具体取决于其性质。并非每个bug 修复或诊断补丁程序都可用作热补丁程序。但热补丁工具的长期目标是为关键补丁程序更新提供热补丁功能。

（5）不能在停机时间使用热补丁程序。

（6）如果可能有停机时间，则应以常规补丁程序方式安装所有相关的bug 修复。

三. Online Patch 操作示例

测试环境是11.2.0.3：

SQL> select * from v$version;
