Required data
To calculate the space allocation requirements, estimate some values for the environment in which you want to run CICS® IA.
Refer to the worksheet supplied in Table 1 and Table 2. These values are used in later
calculations.
Required Data | Description | Value |
---|---|---|
PROG_TRAN_RATIO | Estimate of the number of transactions and program associations. For example, program PROGA can be associated with more than one transaction. | |
NUM_CICS_PROG | Number of programs that contain EXEC CICS commands. | |
AVG_EXEC_LONG | Average number of EXEC CICS calls, per program, that have a data space key greater than 32. These commands are the EXEC CICS ENQ and EXEC CICS DEQ. | |
AVG_EXEC_SHORT | Average number of EXEC CICS calls, per program, that have a data space key less than or equal to 32. These commands are all EXEC CICS commands apart from EXEC CICS ENQ and EXEC CICS DEQ commands. | |
AVG_DTP | Average number of EXEC CICS DTP calls, ALLOCATE, CONNECT, SEND, CONVERSE, and FREE commands. | |
NUM_DB2_PROG | Number of programs that contain EXEC SQL commands. | |
AVG_DB2 | Average number of EXEC SQL calls per program. | |
NUM_IMS_PROG | Number of programs that contain EXEC IMS™ commands. | |
AVG_IMS | Average number of EXEC IMS calls per program. | |
NUM_MQ_PROG | Number of programs that contain EXEC MQ commands. | |
AVG_MQ | Average number of EXEC MQ calls per program. | |
NUM_AFF_PROG | Number of programs that contain EXEC AFF commands. | |
AVG_AFF | Average number of EXEC AFF calls per program. | |
NUM_NATURAL_PROG | Number of Natural programs that contain ADABAS or PROGRAM calls. | |
AVG_NATURAL | Average number of ADABAS or PROGRAM calls per Natural program. |
Required Data | Description | Value |
---|---|---|
NUM_REGION_V | Number of CICS regions sharing the VSAM file. This value is required to calculate the VSAM file space allocation. | |
NUM_REGION_D | Total number of CICS regions in which CICS IA is collecting. This value is required to calculate the DB2® table and index sizes. The CICS IA DB2 database can contain data from more than one set of VSAM files. |
