Executing and deleting commands with FILEMGMT

Executing commands

Commands are executed on the appropriate commands screen.

To invoke the Execute Commands screen:

1. Issue the COMmands command (or press F6) from a screen that supports the command.
2. Select the commands you want to execute and press F6.

Note: Before you execute commands in Active mode that were previously executed in Inactive mode, run DDGEN against the file. Running DDGEN ensures that the dictionary file definition reflects the current status of the Model 204 file.

Execute Commands screen

Press the F6 (COMmands) key from any screen that supports the command. FILEMGMT displays the Execute Commands screen:

• If you entered a file name on the primary screen, only the commands staged for that file are displayed.
• If you did not enter a file name on the primary screen, the commands for all the files staged under your user ID are displayed.

The following Execute Commands screen shows all the files staged under a user ID.

FILEMGMT displays the names of files and their records, field groups, and fields. For each item, FILEMGMT displays the current or most recently executed command. To the right of the command, FILEMGMT displays the command status — for example, whether the command is pending, was executed successfully, or could not be executed because of an error condition or privilege violation. All the items that have been selected for execution at least once display a status. To the right of the status, FILEMGMT displays the date the command was requested.

FILEMGMT prompts you only for items that are currently staged by displaying an underscore character (_) in the prefix area to the left of the item name.

If a requested operation affects a set of records, field groups, or fields (for example, a file creation or record definition), FILEMGMT displays a prefix prompt only for the highest order of entity type. For example, file creation is a single operation, affecting the file and all of its records, field groups, and fields. Typing X in the file prefix area and pressing F6 confirms the file creation and automatically submits for execution all the Model 204 commands constructed for this file and its entries.

Execution options

The dictionary administrator determines the default execution option and the available options. Execution options determine how and when FILEMGMT executes the commands on the Execute Commands screen.

If your system supports more than one mode, you can override the default by specifying the option you want on the ACTIVE or INACTIVE line of the Execute Commands screen. Your choice affects only the items you select for the current session. The default option is restored for subsequent sessions.

FILEMGMT provides the following options:

Option	Function
Active Immediate	Commands for selected items are executed immediately after FILEMGMT verifies that you have the necessary privileges to execute the commands.
Active Delayed	Commands for selected items are flagged as pending after FILEMGMT verifies that you have the necessary privileges to execute the commands. FILEMGMT executes the commands at a later time in batch mode. Refer to the appropriate section of the Rocket Model 204 Installation Guide for your operating system for more information.
Inactive USE File	Commands for selected items are written to a Model 204 directed output (USE) file. Your run must contain one of these print statements: OUTxxxx file DD statement in the JCL option (z/OS and z/VSE) DEFINE PRINTER statement in the Model 204 CCAIN data stream (z/VM) If no name is specified, FILEMGMT uses the default file, OUTFILE. If OUTFILE is used, it must be defined with the option DISP=MOD.
Inactive Procedure File	Commands for selected items are written to a specified procedure file. The procedure file name has the format: FIM.acct.date.time Where: acct is your login account name. date is the current date (MMDDYY). time is the current time (HHMMSS).

Follow these guidelines when determining execution options:

• If you select the ACTIVE option, FILEMGMT checks all necessary passwords and privileges. These must be correct before FILEMGMT actually executes the command. If your login account password or the file password is invalid for a particular command, FILEMGMT reports an error condition on the line containing the file name.
• If the default is INACTIVE, and both USE and procedure files are available, the two options have Xs in the prefix area. Delete one of the Xs before you execute commands in the INACTIVE mode.
• INACTIVE option does not generate passwords for OPEN statements.
• INACTIVE option is required if you are recreating or copying a file from an earlier Model 204 release and choose to retain the file format of the earlier release.

The Execute Commands screen displays all the execution options supported by your system, and lets you change (and refine) the option you selected on the File Definition - Organization screen. The option you select on the Execute Commands screen applies to all the commands you select from the screen before you press the F6 (EXEcute) key.

FILEMGMT displays or prompts you for the following information:

Prompt	Response
REPORT Use	Type the name of a directed output (USE) file to which FILEMGMT is to write a printable report. The report has the same format as the Execute Commands screen, except that the REPORT line shows the user account name and the current date and time. If you select this option, your run must contain one of these print statements: OUTxxxx file DD statement in the JCL option (z/OS and z/VSE) DEFINE PRINTER statement in the Model 204 CCAIN data stream (z/VM) Note: Of the four command options described below and in the preceding Execution Options section, the screen prompts only for those that were selected by the DBA on the Dictionary Administration File Management Facility screen.
ACTIVE	Commands can be executed in immediate or delayed mode.
Immediate	Commands are executed as soon as you issue the EXEcute command on the Execute Commands screen and FILEMGMT confirms your privileges. FILEMGMT displays X if this is the default for your system. You can type X to select this option if no X is displayed.
Delayed	Commands are ready for execution. They are assigned a status of pending and can be subsequently executed in batch mode. FILEMGMT displays X if this is the default for your system. You can type X to select this option if no X is displayed.
INACTIVE	Commands can be written to a Model 204 directed output (USE) file or stored in a procedure.
Use	Commands are written to the USE file specified to the right of the Use prompt. The necessary print statements are the same as for the REPORT Use prompt. Select this option by typing X to the left of the prompt.
ProcFile	Commands are written to the procedure file specified to the right of the ProcFile prompt. The format for the procedure file name is described in the Execution options section. Select this option by typing X to the left of the prompt.
Password	If you selected the ProcFile option, enter the password (if any) associated with the procedure file. Type a valid password for the file (1-10 characters containing no spaces, commas, or colons).
Filename	FILEMGMT displays the name of the file that you entered on the primary screen, or displays the names of all files staged under your user ID. If the file is currently staged (for example, for a file creation), you can select the file by typing X in the prefix area to the left of the file name. The absence of a prefix prompt means that the file is no longer staged for a command. FILEMGMT displays on the same line as the file name: FILEMGMT command requested for the file. See Commands generated from FILEMGMT for a listing of the commands. Status of the command. A status preceded by an asterisk (*) indicates that the command cannot be executed until you provide FILEMGMT with more information. Any other status indicator shows the results of the most recent execution attempt. A blank status indicates the command was never selected for execution. Status Meaning CmdGen'd Commands were generated in INACTIVE mode. EXEC PENDING You executed a command in ACTIVE Immediate mode and were restarted or the system crashed before the command was completed. To recover, run DDGEN to ensure your dictionary is synchronized, and reissue the command. FilePriv The operation failed because you have insufficient file privileges. Fistat The file is physically or logically inconsistent. (See Restarts.) M204.nnnn The operation failed because of an incorrect password or some other error condition. nnnn indicates the Model 204 error message number. OpenError FILEMGMT was unable to open the file. Pending The command was selected but is not yet executed. Pending status occurs in ACTIVE DELAYED mode. PrevExecuted The command for a field was previously executed as part of a different record or field group. *REC DEFN REQD The record must be completely defined before the command for the record can be executed. SizeError The available space is insufficient for an INCREASE command. *SIZING REQD The file was staged for CREATE, but sizing information was not provided. Successful The command was executed successfully. UserPriv You attempted to execute a CREATE command and do not have superuser privileges. The date (MM/DD/YY) the command was requested. If the command status is the result of an error or incomplete execution, an asterisk appears in front of the date.
Password	If required, type a valid password for the file (1-10 characters containing no spaces, commas, or colons). FILEMGMT indicates on the same line whether the file is active or inactive. Active or Inactive indicates the mode in which the commands for this file were last executed. If you re-execute the commands, you can change the execution mode by selecting another option at the top area of the screen. For more information, see the discussion of execution options, above.
Record	FILEMGMT displays the name of a record, field group, or field for which a command Field has been generated. The command, status, and execution date are displayed on the same line. For more information about the line, see the Filename prompt, above.
