Parameter
zcsa/calendar_area
Short Text
Size of Calendar Buffer
Parameter Description
Specifies the size of the calendar buffer. This buffer holds all defined holiday and factory calendars. Calendars are stored in the data base in tables TFACS and THOCS. The buffer is initialized at system startup: all defined calendars are loaded. If the buffer is not large enough for all calendars, then they are loaded dynamically when they are accessed.
If problems arise relating to the buffer capacity, you can save storage space by deleting unused calendars or increasing the size of the calendar buffer.

Are other parameters affected or dependent?
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_11=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.
Values allowed
Buffer size in bytes.
Recommended value for systems of all sizes
500,000 bytes.
