Tenant virtual processor class

Tenant virtual processor classes are specific to tenant databases. If you configure multitenancy for your Informix® instance, you can specify that session threads for tenant databases are run in tenant virtual processors instead of CPU virtual processors.

You can create a tenant virtual processor class by defining the class and the number of virtual processors when you create a tenant database. You can assign a tenant virtual processor class to multiple tenant databases. Set the VP_MEMORY_CACHE_KB configuration parameter to create a private memory cache for each CPU virtual processor and tenant virtual processor.

A tenant virtual processor class is automatically dropped when all tenant databases that include the virtual processor class in their definitions are dropped.
