今天在opatch遇到了inventory目录的问题，下面对inventory手动创建做了一点实验。
测试环境:OS RHEL 5.8 DB:10.2.0.5.10 RAC环境
1，使用命令手动创建
[oracle@rac2 bin]$ /u01/app/oracle/product/10.2.0/crs/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=$ORA_CRS_HOME ORACLE_HOME_NAME=OraCrs10g_home CLUSTER_NODES=rac1,rac2 "INVENTORY_LOCATION=/u01/app/oracle/oraInventory"
Starting Oracle Universal Installer...
No pre-requisite checks found in oraparam.ini, no system pre-requisite checks will be executed.
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oracle/oraInventory
'AttachHome' was successful.
[oracle@rac2 ContentsXML]$ cat inventory.xml
<?xml version="1.0" standalone="yes" ?>

</HOME_LIST>
</INVENTORY>

</NODE_LIST>
</HOME>
<HOME NAME="OraDb10g_home1" LOC="/u01/app/oracle/product/10.2.0/db" TYPE="O" IDX="2">
<NODE_LIST>
<NODE NAME="rac1"/>
<NODE NAME="rac2"/>
</NODE_LIST>
</HOME>
</HOME_LIST>
</INVENTORY>
如果要创建集群中的所有节点的inventory，去掉-noClusterEnabled参数，如果有多个实例包括ASM，需要增加多次，注意ORACLE_HOME参数的值的不同。
下面是测试inventory目录是否创建成功，如果命令正常执行，说明成功。
[oracle@rac2 ContentsXML]$ cd /u01/app/oracle/product/10.2.0/db/OPatch

OPatch succeeded.
2，使用脚本创建
dd[oracle@rac2 oracle]$ rm oraInventory -r
[oracle@rac2 oracle]$
[oracle@rac2 bin]$ pwd
/u01/app/oracle/product/10.2.0/crs/oui/bin
[oracle@rac2 bin]$ ./attachHome.sh
Starting Oracle Universal Installer...
No pre-requisite checks found in oraparam.ini, no system pre-requisite checks will be executed.
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oracle/oraInventory
SEVERE:Remote 'AttachHome' failed on nodes: 'rac1'. Refer to '/u01/app/oracle/oraInventory/logs/AttachHome2013-04-29_07-37-05PM.log' for details.
You can manually re-run the following command on the failed nodes after the installation:
/u01/app/oracle/product/10.2.0/crs/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/u01/app/oracle/product/10.2.0/crs ORACLE_HOME_NAME=OraCrs10g_home CLUSTER_NODES=rac1,rac2 CRS=true "INVENTORY_LOCATION=/u01/app/oracle/oraInventory" LOCAL_NODE=<node on which command is to be run>.
'AttachHome' failed.
[oracle@rac2 bin]$ cd $ORACLE_HOME/oui/bin
[oracle@rac2 bin]$ ./attachHome.sh
Starting Oracle Universal Installer...
No pre-requisite checks found in oraparam.ini, no system pre-requisite checks will be executed.
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oracle/oraInventory
'AttachHome' was successful.
[oracle@rac2 bin]$
脚本创建，默认是在集群中所有的节点创建inventory目录。
下面是单实例创建的方法：
Steps To Recreate Central Inventory(oraInventory) In RDBMS Homes [ID 556834.1]
Execute runInstaller with -attachHome option for Oracle Home.
% ./runInstaller -silent -ignoreSysPrereqs -attachHome ORACLE_HOME=“<Oracle_Home_Location>” ORACLE_HOME_NAME=“<Name_Of _Oracle_Home>”
> setup.exe -silent -ignoreSysPrereqs -attachHome ORACLE_HOME=“<Oracle_Home_Location>” ORACLE_HOME_NAME=“<Name_Of _Oracle_Home>”
For Example:ORACLE_HOME=/u01/app/oracle/product/10.2.0.3
ORACLE_HOME_NAME=OraDb10g_home1
% ./runInstaller -silent -ignoreSysPrereqs -attachHome ORACLE_HOME=“/u01/app/oracle/product/10.2.0.3” ORACLE_HOME_NAME=“OraDb10g_home1”
If you have more than one oracle home you have to repeat STEP 4 for all remaining Oracle Homes making sure to provide unique ORACLE_HOME_NAME’s for each ORACLE_HOME.
inventory目录手动创建：等您坐沙发呢！
