CTOCSF – Copy the Message Statistics File

The CTOCSF utility copies the Message Statistics file. The utility is generally used to create a new Message Statistics file whose size is better adapted to the site’s needs.

Before copying the file, the following steps must be followed:

1. If the Control-O monitor is active, stop the Control-O statistics collection task using the command

   F CONTROLO,STOPSTAT

   Message CTO189I indicates that statistics accumulation has stopped.

2. Verify that no users have allocated the Message Statistics file using Control-O screen OM.
3. Rename the current Message Statistics file (input file for the copy operation), for example, using ISPF 3.2 or 3.4.
4. Perform the following steps:
   1. Enter ICE and select Customization.
   2. In the Customization screen, set Product ID to CTO.
   3. Select major step "Customize Control-O Dataset Parameters."
   4. Select minor step "Control-O Dataset Parameters."
   5. Change parameter STREC# from (for example) 10000 records to 20000 records to change the size of the new Message Statistics file.
   6. Select minor step "Save Parameters Into Product Libraries."
   7. Select minor step "Allocate and Format CTO Statistics Files."
   8. Create and format a target statistics file using the CTOFRSTF program.
   9. Submit the job and create a new Statistics file.
5. Edit member CTOCSFJ in the Control-O JCL library. Change DD statement DASTF DSN to match the name specified in Step 3.
