Update Manager uses Microsoft SQL Server and Oracle databases to store information. Update Manager does not provide a reporting capability, but you can use a third-party reporting tool to query the database views to generate reports.


The Update Manager database does not contain information about the objects in the inventory, but contains internal inventory entity IDs. To get the original IDs for virtual machines, virtual appliances, and hosts, you must have access to the vCenter Server system database. From the vCenter Server system database, you can retrieve the ID of the objects that you want to access. To obtain the Update Manager database IDs of the objects, Update Manager adds the prefix vm- (for virtual machines), va- (for virtual appliances), or host- (for hosts).
