Abstract

A method, and associated computer system, for redistributing software packages in a distributed computer network after a failed distribution attempt is made in a distributed computer network by a master network device. The method includes determining which intermediate distribution devices or servers were affected by the failed distribution. Then for each of these devices, identifying a distribution job that failed and retrieving from the particular distribution device stored distribution parameters, such as distribution control commands, a set of distributed packages, and a distribution list, used in the failed distribution. The method continues with building new distribution commands for the failed distribution job from the retrieved distribution parameters and then performing a redistribution of the set of software packages utilizing the new distribution commands.

6. The method of claim 4, wherein the redistribution performing is completed by a distribution manager running on the affected intermediate distribution device and the redistribution performing includes transmitting the new distribution commands from the redistribution tool to the distribution manager.

7. The method of claim 1, wherein the determining comprises accessing and searching records of failed distribution files storing information parsed from error alert messages generated within the distributed computer network.

8. The method of claim 7, further including after the redistribution performing, updating the failed distribution files to remove information corresponding to the failed distribution job at the affected intermediate distribution device.

9. The method of claim 1, wherein the distribution parameters retrieving further includes retrieving a distribution list for the failed distribution job and wherein the new distribution commands building includes creating a distribution list for use in the redistribution identifying the recipient network device that are to receive the set of software.

10. A computer system for distributing software in a distributed computer network having a plurality of intermediate distribution servers and end user devices communicatively-linked to a data communications network, comprising:

a master network device linked to the communications network and adapted for transmitting a distribution job for a set of software packages to select ones of the intermediate distribution servers, wherein the distribution job includes distribution data comprising a distribution list of the end user devices and distribution parameters including instructions on how to install the software packages; and

a redistribution tool configured for retrieving the distribution parameters and the distribution list from an affected one of the selected intermediate distribution servers that failed to complete the distribution job, for building commands for a redistribution of the distribution job from the retrieved distribution parameters and the distribution list, and issuing the redistribution commands to a distribution manager running on the affected intermediate distribution server to cause initiation of a redistribution job.

11. The computer system of claim 10, wherein the affected intermediate distribution server includes a log file for the failed distribution job and the redistribution tool automatically accesses and searches the log file to retrieve the distribution parameters and the distribution list for the failed distribution job.

12. The computer system of claim 11, wherein the log file further includes a list of the software packages for the failed distribution job and the redistribution tool retrieves the list and includes the list in the redistribution commands.

13. The computer system of claim 10, wherein the redistribution tool includes an interface manager configured for generating an interactive user interface at the affected intermediate distribution server to display the redistribution commands and to receive approval input from an operator prior to the issuing of the redistribution commands.

14. The computer system of claim 10, wherein the redistribution tool is maintained on a server linked to the communications network and is called from the affected intermediate distribution server to execute on the affected intermediate distribution server.

16. The method of claim 15, wherein the redistribution tool running includes identifying the failed initial distribution on the affected intermediate server, retrieving a copy of the distribution commands for the failed initial distribution stored by the affected intermediate server, and using the retrieved distribution commands in the generation of the redistribution commands.

17. The method of claim 16, wherein the redistribution tool running further includes displaying the redistribution commands at the affected intermediate server, querying for an approval of the displayed redistribution commands, and if approval received, issuing the redistribution commands to a distribution manager of the affected intermediate server to initiate the redistribution performing.

19. The method of claim 18, wherein the threshold limits are predetermined and stored in memory accessible during the comparing and wherein the threshold limits are selected to differ for at least some of the failure types.

20. The method of claim 18, further including running a redistribution tool on a one of the network devices determined to have failed to complete the package distribution to automatically generate a set of redistribution commands and performing a redistribution of software applications contained in the package distribution from the affected intermediate server based on the redistribution commands.

21.

22. The method of claim 18, wherein the error alert processing further includes retrieving identification data on a network device affected by the package distribution failure, the method further includes determining with the identification data whether the affected network device is included on an outage list, and further wherein the job ticket creating is not completed when the affected network device is determined to be included on the outage list.

23.
