Abstract: A database comparison tool is provided that compares a source database to a target database. The database comparison tool performs the comparison in two steps: an initial comparison step and a confirmation step. In the initial comparison step, a server retrieves rows of a table from source and target database tables with a query using an agent. The server compares rows by using a hash value for all non-key columns. The resulting rows are flagged as potentially being out-of-sync. In the confirmation step, the server fetches the potentially out-of-sync rows from the source and target databases and performs a literal value-by-value comparison. Each agent receives a batch of rows, inserts the batch of rows into a temporary table, and performs a join operation between the temporary table and the actual source or target table. The agent returns the rows resulting from the join operation to the server.

Abstract: In accordance with an embodiment, described herein is a system and method for provisioning cloud services across heterogeneous computing environments. A plurality of provisioning instructions stored on a configuration management server can be partitioned into a plurality of ranges. A plurality of client nodes connected to the configuration management server can be configured into a plurality of groups, each group providing one or more computing environments on one or more virtual machines for hosting a cloud service. Each computing environment in a particular group can be associated with a provisioning instruction launcher that specifies a particular range of provisioning instructions. When a virtual machine in a particular group reboots, the computing environment on the virtual machine searches for the latest provisioning instruction in the range corresponding to the particular group.
