分類： Oracle
【環境參數】
Host OS:：Win7 32bit
Client OS:：Oracle Enterprise Linux 5
虛擬機：VMware 10.0..1
Oracle版本：Oracle 11g R2
【障害場景一再現】
1、障礙描述：
在CentOS或者Oracle Enterprise Linux環境下，安裝Oracle11gR2的過程中，用戶在安裝Oracle時，
選擇了“Create and Configure a database”，在安裝的過程中出現了“[INS-20802] Oracle Net Configuration Assistant failed”的錯誤，
具體如下圖所示。

【障礙場景二再現】
1、障礙描述：
用戶在安裝Oracle時，選擇的是“Install database software only”之后，啟動DBCA時出現錯誤。
在用戶僅僅安裝完Oracle11gRoot數據庫軟件后（即，用戶在安裝Oracle時，選擇了“Install database software only”），准備通過netca來配置listener時，在執行netca的時候報出“[INS-20802] Oracle Net Configuration Assistant failed”錯誤。
2、障礙場景圖片
【問題原因】
DBCA程序由於缺少補丁包無法正常啟動，需要打p8670579_112010_LINUX.zip補丁包。
【解決方案】
到下述網站上下載p8670579_112010_LINUX.zip補丁包,按照README.txt步驟將該補丁打上后執行dbca,,創建db的圖形出來了,問題解決.
p8670579_112010_LINUX.zip下載：
免費下載地址在 http://linux.linuxidc.com/ （Linux公社的服務器）
用戶名與密碼都是www.linuxidc.com
具體下載目錄在 /2012年資料/8月/28日/Oracle 11gR2執行DBCA報錯誤
網上搜索了很多相關的帖子,基本上說的是64位的機器安裝了32位的數據導致的,但我的機器是32位的,
下載的oracle版本也是32位的,但也報這個錯誤.先不管了,按照網上說的需要打補丁p8670579_112010_LINUX.zip.
【補丁安裝步驟】
1.下載p8670579_112010_LINUX.zip,並上傳到服務器上的目錄/ftp
2.確認是否配置了ORACLE_HOME
[oracle@primary]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/db_1
3.檢查perl的版本,需要5.00503以上的版本
[oracle@primary 8670579]$ perl -v
This is perl, v5.8.8 built for i386-linux-thread-multi
4.Verify the OUI Inventory.
$opatch lsinventory //若沒有將opath的路徑加入到oralce用戶的PATH變量中，也可以使用以下命令：$/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch lsinventory
注意：
opatch命令是在$ORACLE_HOME/OPatch/目錄下,環境變量PATH中沒有包含該目錄的話,直接敲入opatch命令是提示找不到改命令的,這時需要將該目錄加入到PATH中.
命令結果如下所示：
5.解壓縮補丁包
$unzip p8670579_112010_LINUX.zip
6.確保數據庫已經停止。
$cd /ftp/8670579
$opatch apply //在8670579這個目錄下執行此命令
7. 若打完補丁成功，則會出現下屬結果。
【補丁補充的是什么地方】

README.txt里的說明如下:

=========================================================================
Interim Patch for Base Bug: 8670579
=========================================================================
Date: 25th February 2010
-------------------------------------------------------------------------
Platform. Patch for : Linux x86
Product Patched : NETWORK
Product Version # : 11.2.0.1
RAC Rolling Installable : YES
Online Installable : NO
Bugs Fixed by this patch:
-------------------------
8670579 - DBBETA :NETCA/DBCA FAILED WITH HOTSPOT VIRTUAL MACHINE
Patch Preinstall Steps
----------------------
1. For non-recommended patches, you must have the exact symptoms
described in the service request (SR).
2. Confirm the version of Perl installed and configured for the ORACLE_HOME.
Oracle requires that all customers have at least Perl 5.00503 installed
and configured for patching activities inside the ORACLE_HOME. Follow
these steps to check the Perl version for the ORACLE_HOME being patched:
- source the ORACLE_HOME environment
- execute "perl -v"
- verify that the returned version of Perl is 5.00503 or higher
If the Perl configured for the ORACLE_HOME is not at 5.00503 or
higher, follow the directions in this metalink note to update to
a more recent version:
https://metalink.oracle.com/metalink/plsql/ml2_documents.showNOT?p_id=189489.1
3. Verify the OUI Inventory.
OPatch needs access to a valid OUI inventory to apply patches.
Validate the OUI inventory with the following command:
% opatch lsinventory
If the command errors out, contact Oracle Support and work to validate
and verify the inventory setup before proceeding.
4. Review and download the latest version of OPatch.
Oracle recommends that all customers be on the latest version of OPatch.
Please review the following metalink note and follow the instructions
to update to the latest version if needed:
https://metalink.oracle.com/metalink/plsql/ml2_documents.showNOT?p_id=224346.1
5. Confirm executables appear in your system PATH.
The patching process will use the unzip and the opatch executables. After
sourcing the ORACLE_HOME environment, confirm both of these exist before
continuing:
- "which opatch"
- "which unzip"
If either of these executables do not show in the PATH, correct the problem
before proceeding.
6. Create a location for storing the unzipped patch. This location
will be referred to later in the document as <patch_top>.
7. Unzip the patch zip file into the <patch_top>.
unzip -d <patch_top> <zip_file>
8. Shut down services running from the ORACLE_HOME.
Before applying this patch, do a clean shut down of all services
running from the ORACLE_HOME.
(a) In a non-RAC environment:
Shut down all services that are running from this ORACLE_HOME.
Confirm the return status from each shutdown command to verify
the shutdown is successful and there are no errors.
(b) In a RAC environment:
For each node in the RAC system, shut down the services for
the specific machine that are running from the ORACLE_HOME.
OPatch will be used on each node in the RAC system one at
a time. If this patch is not rolling RAC installable treat
it as a non-RAC environment and shut down all services.
As an example, in the case of a two node RAC system:
1. Stop instances running on node 1.
2. Run 'opatch apply <patch_top>/8670579' on node 1.
3. When the apply finishes, opatch asks for confirmation
before going on to apply the patch to node 2.
4. Start instances on node 1.
5. Stop instances running on node 2.
6. Ask opatch to continue to applying the patch to node 2.
7. Start instances on node 2.
9. Apply pre-requisite updates.
Patch Installation Steps:
-------------------------
1. Set your current directory to the directory where the patch is located.
% cd <patch_top>/8670579
2. Apply the patch.
Use the following command to apply the patch to the ORACLE_HOME:
% opatch apply
When OPatch starts, it will validate the patch and make sure there
are no conflicts with the software already installed in the ORACLE_HOME.
OPatch categorizes two types of conflicts:
(a) Conflicts with a patch already applied to the ORACLE_HOME
In this case, please stop the patch installation and contact
Oracle Support Services.
(b) Conflicts with subset patch already applied to the ORACLE_HOME
In this case, please continue the install, as the new patch
contains all the fixes from the existing patch in the ORACLE_HOME.
The subset patch will automatically be rolled back prior to the
installation of the new patch.
Patch Post Install Instructions:
--------------------------------
sqlplus / as sysdba
exec SYS.DBMS_METADATA_UTIL.LOAD_STYLESHEETS;
Patch Deinstallation Instructions:
----------------------------------
1. Make sure to follow the same pre-install steps when deinstalling
a patch. This includes verifying the inventory and shutting down
any services running from the ORACLE_HOME / machine before rolling
the patch back.
2. Change to the directory where the patch was unzipped.
% cd <patch_top>/8670579
3. Run OPatch to deinstall the patch.
% opatch rollback -id 8670579
注意：
opatch命令是在$ORACLE_HOME/OPatch/目錄下,環境變量PATH中沒有包含該目錄的話,直接敲入opatch命令是提示找不到改命令的,這時需要將該目錄加入到PATH中.
