Abstract

A method for recovering data of a cell in a Distributed Computing Environment (DCE) wherein each cell includes a server associated with a database, a DCE administrator workstation with DCE administrator software for managing the cell, and a plurality of users being included in at least one organization. This method comprises the following steps which are automatically performed by the DCE administrator software after initialization by the administrator workstation: a) generating for each organization, the DCE commands necessary for recovering all data associated with the users included in the cell, and b) building an executable program comprising the generated commands and data associated with each user included in the cell, the executable program being used to restore or duplicate the cell.

Claims

1. A method for automatically recovering the data of a cell in a Distributed Computing Environment (DCE) system comprising at least a cell and wherein each cell includes at least a server associated with a database, a DCE administrator workstation associated with DCE administrator software for managing the cell and a plurality of users, said users being included in a plurality of organizations;

said method comprising the following steps, which are automatically performed by said DCE administrator software after initialization by said administrator workstation;

in response to a request for a backup or duplicate operation,

listing all of said plurality of organizations by extracting from the cell data defining each of said organizations, and generating for each of said organizations, DCE commands necessary for recovering all data associated with the users included in said cell including data to manage said users, including the step of for each of said plurality of organizations, generating DCE commands necessary to create the organization and to list all users belonging to the organization; and

building an executable program comprising said generated DCE commands and data associated with each user included in the cell, said executable program being used to restore or duplicate said cell.

2. The Method according to claim 1, wherein the step of generating includes the following steps for each organization:

generating DCE commands necessary to add each user to said organization; and

generating DCE commands to create user characteristics of the users.

3. The method according to claim 2, comprising the following step performed before the step of generating DCE commands to create characteristics of the users:

getting a group within said organization to which said user belongs.

4. The method according to claim 3, further comprising the step of building a set of files containing both DCE commands and data.

5. The method according to claim 4, used to backup data belonging to users and data used by the DCE administrator to manage the users of said cell.

6. The method according to claim 4, used to duplicate a cell, further comprising the step of installing a new cell and configuring DCE software server code on a server of said new cell.

7. The method according to claim 6, further comprising the step of reworking data of said set of files in order to take into account a naming convention specific to said new cell.

8. The method according to claim 7, wherein said set of files is converted into an executable program.

9. The method according to claim 8, wherein said executable program is sent to the new cell being duplicated in order to be executed.

10. A method according to claim 2, wherein the step of generating DCE commands necessary to create said organization includes the steps of:

generating all the DCE commands necessary to create said organization; and

storing said all the DCE commands in one file.

11. A method according to claim 1, wherein all of the data needed to duplicate said all data associated with the users included in said cell, are contained within a single database;

and

said building step includes the step of accessing only said single database for recovering said all data associated with the users included in said cell.
