SMF reports are gathered for many products to aid in configuration or measure performance. The CA MIM product suite has SMF reporting options available for all product components and allows for dynamic de/activation of these reports at will. This documentation provides examples on generating SMF reports for CA MIM and is to be used with chapter six of the CA MIM Programming Guide.

CA MIM uses a single SMF record for the record collection process. Using record subtypes, you can identify the statistical records to be collected for different reports available under the CA MIM facilities (such as GDIF, ECMF,TPCF, and so on). The major steps involved in the report generation process are:             

  1. Specify the SMF record number on a MIMINIT RECORDTYPE statement in the initialization member. Once this is set, you should not need to change it. (The default Recordtype is 189).
  2. Specify the record collection criteria using the SETOPTION command and begin the record collection process. Note that you must allow the record collection process to run for a while before dumping the SMF records to data sets.                      
  3. Dump the SMF records to a usable data set through the IBM IFASMFDP utility.                                                                
  4. Run a report or create a report output file.     

Before any statistical records can be collected for use in the reporting process, you need to specify an SMF record number. To do this, you place a MIMINIT RECORDTYPE initialization statement in the initialization member. For example, if you decide to use the default SMF record number of 189, then you would specify the following statement in the initialization member: MIMINIT RECORDTYPE=189                                                      

Now you are ready to specify the record collection criteria for the report or reports you want to run. Use the SETOPTION MIM STATCOLLECT command to specify the type of statistical records to be collected. (SETOPTION CMDS specified in MIMCMNDS)

The following are record subtypes for the CA MIM facility:Specify the SUBTYPE operand to select specific record subtypes for a facility or specify ALL to collect records for all record subtypes available under that facility. The record subtypes correspond directly to the reports available for each facility.

The following are record subtypes for the CA MIM facility:

Record     Facility    Description of Report                                

Subtype                                                                     

                                                                            

CF         CA MIM      CA MIM Control File Performance report is used to  

                       assist you in tuning the CA MIM control files. 

 

FC         CA MIM      CA MIM Control File I/O report details activity in

                       the CA MIM control files. It can be used in

                       conjunction with the CF report to assist with

                       control file placement.

 

VF         CA MIM      CA MIM Virtual Control File I/O Performance

                       report details the activity on the CTC devices.

 

 

The following are record subtypes for the CA MIA facility:

Record     Facility    Description of Report                                

Subtype  

  

TP         GTAF        Specifies the record subtype for CA MIA facilities for

           TPCF        both GTAF and TPCF. The resulting Tape Usage Statistics

                       report shows detailed information about tape device   

                       usage for devices managed by GTAF and TPCF.           

 

 

The following are record subtypes for the CA MII facility:

 

Record     Facility    Description of Report                                

Subtype         

                                                             

CR         ECMF        The CR record subtype is used to produce the CA      

                       MII Job Requeue (CR) report. This report provides a  

                       list of batch job requeue times as well as the names 

                       of the data sets causing the conflicts.              

                                                                             

DC         EDIF        The DC record subtype is used to produce the CA      

                       MII Enhanced Data Set Integrity Benefits (DC)        

                       report. This report summarizes the data set integrity

                       exposures prevented by EDIF.                         

                                                                            

DD         EDIF        The DD record subtype is used to produce the CA      

                       MII Enhanced Data Set Integrity Data Set Violation   

                       (DD) report. This report provides more specific      

                       information about integrity exposures detected and   

                       prevented by EDIF.                                   

                                                                            

EC         GDIF        The EC record subtype is used to produce the         

                       following reports:                                   

                                                                            

                       CA MII QNAME Enqueue/Reserve Count (EC) report.      

                       This report provides detailed information about      

                       enqueues and reserves processed by GDIF.             

 

The following are record subtypes for the CA MIC facility:

Record     Facility    Description of Report                                

Subtype                                                                     

                                                          

CN         GCMF        Provides an audit trail of cross-system commands      

                       issued through GCMF.                                  

 

For example, the following command tells CA MIM to collect statistics for the report subtype CF:

 

F MIM,SETOPTION MIM STATCOLLECT(SUBTYPE=CF)  

                                

The SETOPTION MIM STATCYCLE and STATINTERVAL parameters are used to determine the how long MIM waits between each statistical sampling, and how often samples are recorded to SMF datasets. To review these values, issue a MIM DISPLAY OPTION ALL command.           

 

The following are sample command syntax statements to enable MIM SMF tracing. Prior to issuing stat collect commands, issue these display commands to reset statistics:

 

D IO(CF,RESET)

D SERVICE=RESET     

 

If you wish to issue multiple subtypes, it's required that users re-issue the command for each subtype. For example, to enable SMF tracing for EDIF, you need to issue:

 

F MIM,SETOPTION EDIF STATCOLLECT(SUBTYPE=DC)

F MIM,SETOPTION EDIF STATCOLLECT(SUBTYPE=DD)

 

Noting the above statement, here are the STATCOLLECT commands for each component, utilizing the 'F MIM' TSO modifier command syntax:    

                                                    

F MIM,SETOPTION MIM STATCOLLECT(SUBTYPE=CF,FC,VF)                                    

F MIM,SETOPTION GDIF STATCOLLECT(SUBTYPE=EC)                                      

F MIM,SETOPTION ECMF STATCOLLECT(SUBTYPE=CR)                                      

F MIM,SETOPTION EDIF STATCOLLECT(SUBTYPE=DC,DD)                                   

 

Once you have run your report, please review the MIM programming guide for information on dumping and generating SMF reports via CA Easytrieve.
