if you try to execute the following query:
SQL> select * from OPATCH_XML_INV ;
ORA-29913: error in executing ODCIEXTTABLEFETCH callout
ORA-29400: data cartridge error
KUP-04004: error while reading file
SQL> select dbms_sqlpatch.verify_queryable_inventory from dual;
ORA-20001: Latest xml inventory is not loaded into table
first, you need to download the latest OPatch utility 18.104.22.168.14
second, the error i have faced due to that i am invoking the opatch utility outside ORACLE_HOME…… now you need copy it in your oracle home directory ( its a must ! )
scp -r /newopatch/OPatch/* .
a good reference is Doc ID 1602089.1
