Dbms_datapupm, dump file permissions

Question

Oracle 11.2.0.2
Using dbms_datapipe APIs I can successfully create the dump file. However, that file does not have read or write permissions, so the UNIX user can not zip and ftp the file as required, not can it chmod the permissions. Please, advise. Thanks.

Answer 1

Use ACLs. For example:
hpux > # whoami
hpux > whoami
oradba
hpux > # Create directory /tmp/acl_test for datapump files
hpux > mkdir /tmp/acl_test
hpux > # set directory /tmp/acl_test access to rwx for owner (Unix user oradba) and no access to group and other
hpux > chmod 700 /tmp/acl_test
hpux > # set ACL access to directory /tmp/acl_test file itself to rwx for user oracle
hpux > setacl  -m u:oracle:rwx /tmp/acl_test
hpux > # set ACL access to any file created in directory /tmp/acl_test to rwx for user oracle
hpux > setacl  -m d:u:oracle:rwx /tmp/acl_test
hpux > # set ACL access to any file created in directory /tmp/acl_test to rwx for user oradba
hpux > setacl  -m d:u:oradba:rwx /tmp/acl_test
hpux > # show directory /tmp/acl_test ACLs
hpux > getacl /tmp/acl_test
# file: /tmp/acl_test
# owner: oradba
# group: appdba
user::rwx
user:oracle:rwx
group::---
class:rwx
other:---
default:user:oracle:rwx
default:user:oradba:rwx
hpux > # create Oracle directory object
hpux > sqlplus / << EOF
hpuxcreate directory acl_test as '/tmp/acl_test';
hpuxexit
hpuxEOF
