Step 6--Format the RFS filepools

Bring up the CICS® region and sign onto the CICS region with a userid defined as an authorized user. Enter REXX, the default transaction id associated with the CICRXTRY exec. You should see the following line at the top of the screen, "Enter a REXX command or EXIT to quit" and a "READ" in the lower right hand corner. The cursor is in the lower left hand corner. You have now entered the supplied exec which allows the execution of REXX and REXX/CICS commands interactively.

You may now prepare the filepools for use by entering the command: 'FILEPOOL FORMAT pool1' where pool1 should be substituted by the filepool name you specified in the CICSTART exec.

Note:
The command should be entered as shown, including the apostrophes.

The interactive environment will echo each command at the next available line on the screen and any requested output will also be displayed. The FILEPOOL FORMAT command does not display any information. To determine whether the FILEPOOL FORMAT command worked successfully, enter "SAY RC". If a "0" is displayed on the next available line, the FILEPOOL FORMAT command was successful.

Continue this process until all RFS filepools have been formatted. You only have to format the filepool when a new filepool has been defined, or if you delete and redefine the clusters for an existing filepool.

If, in the process of formatting the filepools or interactively executing REXX or REXX/CICS commands and instructions, you fill the screen, a "MORE" indicator will appear at the bottom right hand corner. To clear the screen, press the ENTER key. Any time you want to clear the screen of data, you may press the CLEAR key. To exit from the interactive environment, you may press the PF3 key which simulates the entering of the "EXIT" REXX instruction. You may also enter the "EXIT" instruction yourself.

The interactive environment also provides for recalling previously entered commands. This is done by pressing the RETRIEVE key. The system has a default setting for this key of PF12. This may be customized using the SETSYS RETRIEVE command. Pressing the RETRIEVE key causes the previously entered line to be re-displayed at the input location. You can then modify this area if required and re-execute the instruction by pressing ENTER. Pressing the RETRIEVE key multiple times will continue to bring the next previously entered command to the input area.
