Description
The size of the user's server tables that are fixed by initialization
For non-SQL processing, FIXSIZE is determined according to the following calculation:
FIXSIZE = 2536 + ((LAUDPROC + 9) * 4)dwr + (LIBUFF + 4)dwr + (LOBUFF + 5)dwr + (LOUTPB)dwr + ((NGROUP + 12) * (NRMTFILE + NFILES + 1)) + (NRMTFILE + 1)dwr + (3 * (NORQS + 1))dwr
where:
- dwr, "double word rounded," means round to the next multiple of eight, unless it already is a multiple of eight.
-
The following adjustments might apply:
- NRMTFILE is zero except for PQO users.
- Add to the NFILES term (since its CCAIN value gets increased automatically by Model 204): +1 if either the SYSOPT 1 bit or 2 bit is set +2 if both the SYSOPT 1 and 2 bits are set
- If the value of the Model 204 KOMMOPT parameter is X '00', the default, extra control blocks are needed. Add 2944 bytes to the FIXSIZE calculation.
- If any SQL threads (IODEV 19) are specified in the CCAIN, add 6328 bytes for C language work areas to the FIXSIZE calculation.
Fixed server tables as well as variable server tables, those that can be modified during the Model 204 run, are discussed in Chapter 2 of the Model 204 System Manager's Guide.
