IAMSMFVS JCL Requirements
The JCL statements required to execute IAMSMFVS are as follows:
EXEC Statement
Specifies the IAM VSAM SMF ANALYSIS program name - IAMSMFVS. A large region parameter may need to be provided, based on the number of data sets that are being tracked. IAMSMFVS uses above and below the 16-megabyte line storage.
DD Statements
The following table describes the required DD statements for running IAMSMFVS. The amount of DASD space required for the temporary work files of SORTIN, SORTOUT, and SORTWKxx will depend entirely on the amount of SMF data that is being processed. A month's history tape is going to require much more DASD space than just a daily snapshot.
DD Name | Description |
STEPLIB or JOBLIB | Specifies the IAM Load Module Library. This statement may be omitted if the IAM modules are in a link list, as is recommended. |
SYSPRINT | Specifies where the IAMSMFVS reports are to be printed. Usually a SYSOUT data set. |
SYSMF | Identifies the file containing the input SMF data. This may be an active SMF data set or any file containing off loaded SMF data. |
SYSIN | Specifies the control card input data set. Usually a DD * data set. |
SORTIN | Specifies a work file that contains extracted SMF data that is used by IAMSMFVS to create the reports. This data will be passed to the external sort. |
SORTOUT | Specifies a work file, which will be returned from the external sort routine. |
SORTWKnn SORTLIB | If there are any DD statements needed by your sort program (i.e. SORTLIB, SORTWKnn, etc.), they must be included. Refer to documentation for your sort. |
VSAMCSV | An optional DD card that when present will contain information on the VSAM data sets in comma separated format (CSV) for easy use in a spread sheet. There will be a row for each VSAM cluster that are in the VSAM EXCP REPORT, and will contain information that is in the EXCP report and Data Set Summary reports. It is to be a sequential data set with no DCB characteristics specified. Only a few tracks are necessary to be allocated for this data set. |
