Shared memory
When a C UDR executes in a virtual processor (VP), it allocates memory from the shared memory of the database server.
To perform this allocation, the UDR takes the following steps:
- Ensures that dynamic memory allocations come from the shared memory
of the database server
All virtual processors can access database server shared memory.
- Chooses a memory duration to associate with this memory
The database server automatically reclaims its shared memory through an associated memory duration.
