Methods and apparatus for providing adaptive private network database schema migration and management processes
System and techniques are described which apply a method for automatic database schema migration. An initial database is installed, according to rules that define tables of data, in an adaptive private network (APN) having a centralized management system including a network control node (NCN) coupled through the APN to a plurality of client nodes, wherein the NCN provides timing and control to the client nodes. An update to the initial database is received, wherein the initial database includes a first table of data stored in a first set of columns and the updated database includes a modified first table having a second set of columns that has a different number of columns as compared to the first table is automatically detected. One or more columns from the second set of columns that are different than the first set of columns are updated for data content.
1. A method of configuration conflict tracking, the method comprising:
determining a current configuration N of an adaptive private network (APN) having a centralized management system that includes a network control node (NCN) coupled through the APN to a plurality of client nodes, wherein the NCN is separate from the plurality of client nodes and the NCN provides timing and control to the client nodes within the APN;
generating, for a user A, a first changed configuration A-1 for the APN and a unique configuration identifier (UCID) list {N, A-1} which are both sent to the NCN;
determining in the NCN to update the current configuration N to the first changed configuration A-1, which becomes the next current configuration, since the NCN finds an identifier for the current configuration N in the UCID list {N,A-1};
generating, for a user B, a second changed configuration B-1 for the APN and a second UCID list {N,B-1} which are both sent to the NCN; and
determining, in the NCN and by searching for and not finding an identifier for the next current configuration A-1 in the second UCID list {N,B-1}, to not update the next current configuration A-1 since the NCN does not find the identifier for the next current configuration A-1 in the second UCID list {N,B-1}, wherein the user B is informed of the second UCID list {N,B-1} discrepancy with respect to the next current configuration A-1.
2. The method of claim 1 wherein the client nodes each comprise an APN appliance that communicates with other APN appliances over the APN using conduits.
3. A system for configuration conflict tracking, the system comprising:
a centralized management system including a network control node (NCN) for providing timing and control through an adaptive private network (APN) to a plurality of client nodes, wherein the NCN is separate from the client nodes; and
a processing node for determining a current configuration N of the APN, generating, for a user A, a first changed configuration A-1 for the APN and a unique configuration identifier (UCID) list {N, A-1} and for sending the first changed configuration A-1 and the UCID list (N,A-1) to the NCN;
wherein the NCN determines to update the current configuration N to the first changed configuration A-1, which becomes the next current configuration, since the NCN finds an identifier for the current configuration N in the UCID list {N,A-1};
wherein the processing node generates, for a user B, a second changed configuration B-1 for the APN and a second UCID list {N,B-1} and sends the second configuration B-1 and the second UCID list (N,B-1) to the NCN; and
wherein the NCN determines, by searching for and not finding an identifier for the next current configuration A-1 in the second UCID list {N,B-1}, not to update the next current configuration A-1 since the NCN does not find the identifier for the next current configuration A-1 in the second UCID list {N,B-1}, wherein the user B is informed of the second UCID list {N,B-1} discrepancy with respect to the next current configuration A-1.
4. The system of claim 3 wherein the client nodes each comprise an APN appliance that communicates with other APN appliances over the APN using conduits.
5. A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:
determining a current configuration N of an adaptive private network (APN) having a centralized management system that includes a network control node (NCN) coupled through the APN to a plurality of client nodes, wherein the NCN is separate from the plurality of client nodes and the NCN provides timing and control to the client nodes within the APN;
generating, for a user A, a first changed configuration A-1 for the APN and a unique configuration identifier (UCID) list {N, A-1} which are both sent to the NCN;
determining, in the NCN, to update the current configuration N to the first changed configuration A-1, which becomes the next current configuration, since the NCN finds an identifier for the current configuration N in the UCID list {N,A-1};
generating for a user B a second changed configuration B-1 for the APN and a second UCID list {N,B-1} which are both sent to the NCN; and
determining, in the NCN and by searching for and not finding an identifier for the next current configuration A-1 in the second UCID list {N,B-1}, to not update the next current configuration A-1 since the NCN does not find the identifier for the next current configuration A-1 in the second UCID list {N,B-1}, wherein the user B is informed of the second UCID list {N,B-1} discrepancy with respect to the next current configuration A-1.
6. The non-transitory computer-readable medium of claim 5 wherein the client nodes each comprise an APN appliance that communicates with other APN appliances over the APN using conduits.
