The IOA LOG File Space Calculation screen (shown in the following figure) enables you to specify values to calculate the required space allocation.

Note: The IOA LOG file is a wrap-around file. Failure to allocate the Log with sufficient space may cause essential messages to be overwritten and lost. For example, if SPY281 messages are lost, then the Control-M Statistics file may be missing the statistics for the most recent job occurrences.

 Enter or change values and press Enter.                                        

 Examine the resulting space requirements.                                      

 Use this space allocation in subsequent installation steps ? ==>      (Y/N)    

 Numbers specified must conform to your sites's peak work load.                 

 -------------------------------------------------------------------------------

              Number of days to retain LOG records  ==> 7                       

  CTM/CTR     Maximum Number of jobs per day        ==> 10000                   

  CTD         Maximum Number of jobs per day        ==> 1000                    

  CTO/CMEM    Number of rules ORDERED per day       ==> 1000

 -------------------------------------------------------------------------------

 Enter the Block Size to be used for the IOA LOG file, Valid values are:        

        6200  The standard block size prior to version 6.2.00                   

       23400  The optimum block size for 3380 DASD devices                      

       27800  The optimum block size for 3390 DASD devices                      

 Allocation : Number of blocks  =  130000        (ILBLKNO)                      

              Number of records =  224200        (LOGSIZE)                      

              Block Size        =  27800         (ILBLKSZ)                      

              3380 Tracks       =  130000      3390 Tracks       =  65000       

Note: You can choose the block size of the IOA LOG file. Also, if you choose a large block size you will increase performance when accessing the IOA LOG file.

If you are going to install Control‑M, Control‑M/Restart or Control‑D, specify the maximum number of jobs to be submitted each day.

If you are going to install Control‑M/Analyzer, Control‑O or the CMEM facility of Control‑M, specify the maximum number of Control‑M/Analyzer, Control‑O or CMEM rules to be processed each day.

Note: These values should meet the requirements of INCONTROL products that you plan to install in the future, using the same IOA environment.

The following parameters are calculated by ICE using the numbers specified:
