A computer readable storage medium includes executable instructions to analyze sort options associated with an input table and a comparison table. It is determined whether a consistent sort can be performed by a first database associated with the input table and a second database associated with the comparison table. A first sort operation is performed on the input table at the first database and a second sort operation is performed on the comparison table at the second database when a consistent sort can be achieved. Sort operations on the input table and the comparison table are executed at a common sort engine when a consistent sort cannot be performed by the first database and the second database.

A computer readable medium includes executable instructions to audit data migration. The executable instructions include instructions to define a data migration path from a source to a target. Audit points are specified within the data migration path. Audit statistics to be generated at the audit points are identified. The audit statistics including data corresponding to individual data values transmitted over the data migration path. Audit rules to be applied against the audit statistics are established.

Apparatus and method for dynamically auditing data migration to produce metadata

A method and apparatus for interfacing with a stateless NFS (Network File System) server. A pseudo-open state is created for a file when a request from a network client for accessing the file is received in a network server. The term pseudo-open data relates to a set of data that is kept in a network server. The pseudo-open describes the state of a file being currently accessed via an NFS server in the network server. The pseudo-open data differs from normal file state data in that it can be created or recreated at will, thus preserving the stateless functionality of the NFS server. Thus, if a request is received at any time and there is no pseudo-open state established for the file, the pseudo-open state will be established or reestablished at that time. If, on the other hand, a request is received for which a pseudo-open state already exists, the overhead of creating the pseudo-open state is avoided, and the existing data is used. The pseudo-open state is stored in a file-system data structure called VNODE. Each active file has an associated VNODE. The pseudo-open state of a file can be then closed. The state of the file can be changed to a higher or lower level of access privilege via open-promotion or open-demotion operations, respectively. Open-demotion refers to the change of a file state to a lower level of access privilege.
