I got ” ORA-06564: object does not exist ”  error in Oracle database.

ORA-06564: object does not exist

Details of error are as follows.

ORA-06564: object string does not exist

Cause: The named object could not be found. Either it does not exist or you do not have permission to access it.

Action: Create the object or get permission to access it

object string does not exist

This ORA-06564 error is related to the named object could not be found. Either it does not exist or you do not have permission to access it.

To solve this error, Create the object or get permission to access it as follows.

SQL>select * from dba_directories where directory_name='DATAPUMP_DIR';
SQL>create or replace directory DATAPUMP_DIR as '/export/dump';
SQL>exit

mkdir -p /export/dump
chown -R oracle:oinstall /export/dump

If you got this error for any  table, you can try to give permission then try again.

GRANT privileges ON object TO user;

GRANT SELECT, INSERT, UPDATE, DELETE ON SCHEMA.TABLE_NAME TO USERNAME;

Another case is as follows.

While Selecting From External Table, ora-6564 occurred against the directory object.

ORA-06564: object <object_name> does not exist

The error obtained is:

ORA-06564: object <object_name> does not exist
06564. 00000 - "object %s does not exist"
*Cause: The named object colud not be found. Either it does not exist or you do not have permission to Access it.
*Action: Create the object or get permission to acces it.
Error at line: 3, column: 15

In the database exists the object <object_name> (is a directory), the path is correct and exists in the same machine, and the user has permission to read, write and execute on that directory.

Customer is accessing the external table of User A from User B by setting alter session set current_schema , then it is failing with ORA-06564

The user should have the proper privileges and login as that user and querying on the table will resolve the issue .
