| Short description : Size of Resident-Table Buffer |
------------------------------------------------------------------------

------------------------------------------------------------------------
| Parameter description : |
| ----------------------- |
| |
| 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). |

| Effects upon other parameters : |
| |
| ipc/shm_psize_10, zcsa/db_max_buftab |
| |
| 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. |
