A method, system, and computer program product for management of large multi-database installations. The method form commences by analyzing a multiple database installation to determine a set of candidate upgrade operations to apply to individual instances of heterogeneous databases in the multiple database installation, and then scheduling an order in which order to apply individual operations from among the set of candidate upgrade operations. In exemplary operation, the candidate upgrade operations comprise database version upgrades, database stack upgrades, and/or database listener upgrades. Some embodiments exploit homogeneity and/or groupings in order to parallelize performance of various upgrade operations during mass upgrade of multi-database installations. In addition to performing upgrade operations in the form of database version upgrades, database stack upgrades, and/or database listener upgrades, the installation can be upgraded by receiving application upgrades.

Upgrade of heterogeneous multi-instance database clusters

Techniques are described for upgrading systems that include a first set of agents for collecting target data from a plurality of targets and sending the target data to a first management server. In an embodiment, a second set of agents is pre-deployed. Each pre-deployed agent is configured to, upon activation, collect target data from a respective target of the plurality of targets and send the target data to a second management server. While the pre-deployed agent remains inactive, an agent from the first set of agents collects and sends the target data to the first management server. When a first batch of one or more pre-deployed agents is activated, each activated agent begins collecting target data and sending the target data to the second management server. For agents not in the first batch, the first set of agents continues to collect and send the target data.
