| Specifies the size of the resident-table (100%) buffer.              |
| This buffer holds entries from tables which have been defined        |
| in the Data Dictionary with buffer type X (buffer all entries        |
| that belong to active clients) and G (buffer entries according       |
| to a generic key specification).                                     |
|                                                                      |

| ipc/shm_psize_10: In standard systems, the resident-table buffer is  |
| stored in shared memory pool 10. If you change the size of the       |
| buffer, then you must change the amount of memory in pool 10 by the  |
| same amount. You can remove the buffer from the pool by setting the  |
| parameter ipc/shm_psize_19=0.                                        |
| Removing the buffer from pool 10 simplifies your profile management. |
| The buffer is stored in its own shared memory segment, which is      |
| allocated automatically when the server is started.  You do not have |
| to change ipc/shm_psize_10 when you change the buffer size.          |
| You cannot remove the buffer from pool 10 in AIX systems.            |
| In AIX, the number of shared memory pools that can be allocated      |
| is limited.                                                          |
|                                                                      |
