Home Screen
The Home screen is displayed when you initiate SMU. Use this screen to:
Specify a Control File
If you specified a Control File when you initiated SMU, the Control File property is prefilled with the file details and the creation date and time is displayed on the status line.
View or change application settings.
Update or clone your application.
Specifying a Control File
To specify a control file, enter the title in the Control File property.
Valid formats of the Control File are:
TESTSYS
TESTSYS ON TESTPK
TESTSYS/LINCCNTL
TESTSYS/LINCCNTL ON TESTPK
(TEST)TESTSYS
(TEST)TESTSYS/LINCCNTL
(TEST)TESTSYS/LINCCNTL ON TESTPK
Viewing or Changing Application Settings
To view or change system settings, display the application, Database, COMS, and OLTP Options screens. If all the settings meet your requirements, enter Y in either the Update or the Clone property.
If you choose to update application settings, a Copy Options screen is displayed. Transmit the screen when you have reviewed the settings. A Change Summary screen is displayed showing the actions that takes place as a result of your changes. Enter Y in the Proceed with update/clone property and transmit.
Do not attempt to change the settings on the Copy Options screen unless you are an experienced user. |
CautionSystem Options Screen
The System Options screen enables you to enter a new application name and new family settings. To enter a new usercode, you must initiate SMU from a privileged usercode. (If you are cloning your application, you must enter either a new usercode, or a new application name and database name.)
If a value is not entered in the ROC file family property, the name of the ROC file family value defaults to the value in the ROC DB family property on the Database Options screen.
Database Options Screen
The Database Options screen enables you to enter:
A new database name
DMS compilers, software usercode and family
New database family settings
If you are cloning the application and not changing the usercode, you must specify a new database name.
If you specify a DMS usercode and family, SMU updates the DASDL to use that DMS software and uses the compilers in that location to compile the database and generated software.
COMS Options Screen
The COMS Options screen enables you to enter a new window name, protected input and protected output file settings.
If you are cloning the application, you must specify a new window name.
OLTP Options Screen
For OLTP-enabled applications, the OLTP Options screen enables you to change OLTP service names.
If the number of server names exceeds the number displayed on the screen, enter N or P in the Next/Prev property to scroll the display.
Copy Options Screen
The Copy Options screen is displayed if you entered Y in the Update property on the Home screen.
If the properties are prefilled with an entry of Y, SMU has detected the need to relocate files within that category. If a property is prefilled with an entry of N, you cannot change it.
If you change a property from Y to N, SMU prevents the relocation of files within that group. You might use this action if a pack has been lost and part of the application is to be restored to another pack. For example, if the object pack was lost, the System object files could be reloaded to another pack. You could then enter Y in the Update property to change the object pack. As the object files are at the target location (and not at the source), the attempted relocation of the object files can be prevented.
Change Summary Screen
The Change Summary screen displays the SMU actions that takes place as a result of the setting changes you have requested. The following table lists the possible messages and their meanings.
| Message | Meaning |
