Subarea communication management configuration

For a subarea communication management configuration (CMC), use the following worksheet:

Table 1. Worksheet for subarea communication management configuration
Step	Description	Formulas (decimal)	Common	Private	DISPLAY STATS ID
1	Number of 4KB pages allocated for the SNA internal trace table.	(trace tab + 4) * 4096	= ________		2
2	Determine the size of the IOBUF parameter. This value is defined in the SNA start list. These buffers hold data transmitted to and from SNA.	Used in questions 4 & 10			3
3	Number of channel-attached communication controllers (NCP) activated and owned by this SNA.	COMMON STORAGE: (NCPs * 1200)	= ________		5
4	Sum value of MAXBFRU parameters for all channel-attached communications controllers activated by this SNA. MAXBFRU is defined in the HOST definition statement of the NCP channel-attached major node definition.	COMMON STORAGE: ((IOBUF size + 98) * 2 * maxbfru NCPs)	= ________		3 & 6
5	Number of PUs defined in this SNA. Include all PUs defined to SNA in PU definition statements, and those controllers defined in CLUSTER definition statements. Include locally attached, remotely attached, dynamically added, switched, ICA, and NCP (including NTRI) PUs.	PRIVATE STORAGE: (defined PUs * 850)		= ________	48 + 67
6	Number of device type LUs defined in this SNA. Include the locally attached LUs, and the LUs attached through an NCP. In addition, include the LUs defined to SNA in LU definition statements, and those devices defined in TERMINAL statements. Do not include applications.	PRIVATE STORAGE: (defined LUs * 820)		= ________	50
7	Number of independent LUs either locally, remotely, or CDRSC defined. Include all independent LUs for which SNA provides boundary function services and all NTRI independent LUs.	COMMON STORAGE: (indep Lus * 270) PRIVATE STORAGE: (indep Lus * 400)	= ________	= ________	80
8	Number of device type LUs owned by this SNA in session with an application program owned by this SNA.	COMMON STORAGE: (LUs w/appls * 500) PRIVATE STORAGE: (LUs w/appls * 420)	= ________	= ________	71
9	Number of device type LUs owned by this SNA in session with an application program in another SNA.	PRIVATE STORAGE: (cross node LU ses * 400)		= ________	73
10	Number of device type (nonapplication) LUs in session with a TSO application.	COMMON STORAGE: (TSO LUs) * (2300 + IOBUF size)	= ________		55 & 3
11	If the SNA topology agent is being used, enter the number of resources being monitored.	PRIVATE STORAGE: (num res * 3500)		= ________	N/A
		Total Common = ________ 1024	= ________KB (totcom)
		Total Private = ________ 1024		= ________KB (totpri)
