Flux requires UPDATE, INSERT, DELETE, and SELECT access to all of its tables, and SELECT permission on FLUX SYSTEM TABLES to access the next available sequence number to generate keys for audit trail entries (e.g., SELECT FLUX_AUDIT_TRAIL_SEQ.NEXTVAL FROM DUAL). Make sure that the Flux database user is granted all of them.
UNIX File Permissions
Flux requires that the user running Flux have read, write and execute permission over the Flux folder. Verify that the permission set is: drwxrwxr-x.
