ORA-29283: invalid file operation
ORA-06512: at line 6
29283. 00000 - "invalid file operation%s"
*Cause: An attempt was made to read from a file or directory that does
not exist, or file or directory access was denied by the
operating system.
*Action: Verify file and directory access privileges on the file system,
and if reading, verify that the file exists.

Any help why iam getting this error?

Hi, @francy77
In schema1 i granted
grant insert,update, delete on t_table_var to ico
Grant the SELECT privilege, as well as INSERT, UPDATE and DELETE.
It sounds like ico has the SELECT privilege only via a role. Roles don't count in AUTHID OWNER stored procedures; all the necessary privileges must be granted directly to the user, or to PUBLIC.
Also, does ico have the CREATE PROCEDURE system privilege?
EDIT: After reading @paulzip 's reply (below) I added AUTHID OWNER above.

You need the select privilege too,
Also, another thing to bear in mind, is the procedure defined with definer rights (permissions are based on who owns the procedure) or invoker rights (permissions are based on who is calling the procedure)?
The default is definer rights.
Example of invoker rights....

create or replace procedure update_par(pcod in varchar2) authid current_user is

I don t know why but granting select was enought, as your suggestion there was a missing SELECT in the grant instruction, so I added it and it works;
The strange thing is that indeed without the select even the delete dos't worked;
