oraInventory存放的是Oracle软件安装的目录信息，Oralce的安装升级都需要用到这个目录，来看看Oracle文档中对这个目录的一点说明：
All Oracle software installations rely on this directory. 
Ensure that you back it up regularly. 
Do not delete this directory unless you have completely removed 
all Oracle software from the system.

oraInventory目录的位置是由oraInst.loc文件决定的：
/etc/oraInst.loc (AIX and Linux Platform)
/var/opt/oracle/OraInst.loc (Solaris and HP-UX platform)

$cat /etc/oraInst.loc 
inventory_loc=/app/oracle/oraInventory
inst_group=dba
删除或丢失oraInventory目录的内容，都有可能导致升级报错，例如在运行opatch时就有可能遇到以下报错：
10G中：
$opatch lsinventory
Invoking OPatch 10.2.0.4.3

OPatch failed to locate Central Inventory.
Possible causes are: 
    The Central Inventory is corrupted
    The oraInst.loc file specified is not valid.
LsInventorySession failed: OPatch failed to locate Central Inventory.
Possible causes are: 
    The Central Inventory is corrupted
    The oraInst.loc file specified is not valid.

OPatch failed with error code 73
$opatch lsinventory
Invoking OPatch 10.2.0.4.3

List of Homes on this system:

Inventory load failed... OPatch cannot load inventory for the given Oracle Home.
Possible causes are:
   Oracle Home dir. path does not exist in Central Inventory
   Oracle Home is a symbolic link
   Oracle Home inventory is corrupted
LsInventorySession failed: OracleHomeInventory gets null oracleHomeInfo

OPatch failed with error code 73
9I中报错：
OPATCH_JAVA_ERROR  : An exception of type "OPatchException" has occurred: 
OPatch Exception:

  An exception occurs
  The inventory pointed at location /app/oraInventory is not valid

在10G中可以运行以下命令进行oraInventory目录重建：
$cd $ORACLE_HOME/oui/bin
$./runInstaller -silent -attachHome \
> ORACLE_HOME=$ORACLE_HOME \
> ORACLE_HOME_NAME="ORACLE_HOME"
Starting Oracle Universal Installer...

no system pre-requisite checks will be executed.
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /app/oracle/oraInventory
'AttachHome' was successful.
js_znjh_1./app/oracle/product/10.2.0/db_1/oui/bin$
10.2.0.2以上的版本，还可以直接运行attachHome.sh脚本：
$cd $ORACLE_HOME/oui/bin    
$./attachHome.sh
Starting Oracle Universal Installer...

No pre-requisite checks found in oraparam.ini,
