Subpool Technology and Advantages:
Starting with Oracle 9i, Shared pool can be split into multiple child buffer pools (Subpool) for management to increase concurrency and reduce competition.
Each subpool of shared pool can be viewed as a mini Shared pool with its own independent free List, memory structure, and LRU
Conclusions1, the parameters associated with the shared pool are: shared_pool_size,shared_pool_reserved_size,_shared_pool_reserved_pct
_shared_pool_reserved_min_alloc
2,shared_pool_reserved_size generally default is Shared_pool_size 5%, this ratio is controlled by the parameter _shared_pool_reserved_pct
3,_shared_pool_reserved_min_alloc controls the minimum allocation size in the reserved pool, with a default size of 4400 and a range of 4000bytes to 6
Article Title: Memstat -- view memory usage of the shared library. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
We can use a tool such as top or System Manager to check the memory usage of each process. However, the memory contains not only the processes you run, but also the

ABAP provides import/export and set/get parameter statements to store and access user memory, server memory, and database. However, many may not know much about this. Next we will test their differences and relationships through examples. 1. After a user logs on to ABAP memory, a maximum of six windows can be opened for one system. This is known as external mode in SAP. In the same window

the database to the library search path. You can use either of the following methods to set the search path for a library file:
Specify the library search path in the environment variable LD_LIBRARY_PATH.
Add the library search path to the/etc/ld. so. conf file.
It is wise to add the paths that may store library files to/etc/ld. so. conf.
The addition method is extremely simple. It is okay to directly write the absolute path of the library file into it, one line at a time. For example:

The system calls MMAP () to map a common file to implement shared memory. System V maps files in the SHM of a special file system to implement shared memory communication between processes.That is to say, each shared memory area corresponds to a file in the shm of the special File System (this is linked through the shmid_kernel structure), and will be elaborated
