dear all,

i have different issue with respect to oracle central inventory.

tota oracle users(userid)=3(oracle,ora10_ca,ora10_gs)
three different oraclehomes for all the above users.

single central inevntory /u01/oraInventory for (ora10_ca,ora10_gs).

another central inventory user(oracle) /oracle/oraInventory.

when i issue optach lsinventory as user (oracle).

i get below message.


$ opatch lsinventory

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

$ echo $ORACLE_HOME
/oracle/ora10g
$ echo $ORACLE_BASE
/oracle
$ id
uid=204(oracle) gid=203(dba) groups=204(oinstall)
$

my query.

though the user(oracle) has seperate ORACLE_HOME,ORACLE_BASE,ORACLEINVENTORY why it needs to point to other other oracle inventory used by user(ora10_ca,ora10_gs).
