ZOMConfig
Enables user to alter the configuration of the ZOM services.
Syntax
ZOMConfig
Comments
This command brings up an option screen which enables the configuration of ZOM to be edited. ZOM configurations are stored in the registry. The options are
| Display Mode | When this option is set to Window, the ZOM status window is displayed while ZOM utilities are being executed. If set to Serial, ZOM status information is displayed a line at a time. If set to None, no status information is displayed. |
| Error Logging | When this option is turned on, ZOM maintains an activity log file as it executes its actions, including the relevant sections of the errors.trc file. It can slow ZOM operations as the log file grows. You can either turn the option off or regularly clear the errors.trc file by executing the commands:
set output errtrace set output terminal |
| Dependency Trace | ZOM maintains an online cross-reference of the dependencies among the objects in your application. This enables many of the powerful features of ZOM, but requires a reasonably large amount of disk space, and slows ZOM operations. Turning off the dependency tracing option saves disk space and speeds ZOM, but disables explosion and implosion operations, and disables ZOM’s display of cross reference information. Note: If you have been running with dependency information turned off, and then decide to turn it on, the dependency information is not automatically loaded for all objects at that time. You must turn dependency on, and then touch all the objects to be certain that the dependency database is up to date, using the following command: ZOMTouch * |
| Default Zim Directory | ZOM requires that all objects be assigned an explicit DirName. This is done by actually putting a value in the DirName field for the object, rather than leaving it $null or blank. If ZOM encounters blank or $null DirNames, it uses this value as the DirName, and puts the dirname in the Object Dictionary on your behalf. |
| Conventions On | If ZOM Conventions are on, ZOM sets two properties on your behalf if certain conditions are met:
|
| Explode Level | The explosion level determines the extent of actions ZOM undertakes automatically on your behalf on objects which depend on objects you directly manipulate. For example, if you destroy the EntitySet Employees, what should ZOM do to the Relationships and Roles which depend on Employees for their existence? Explode level can be set to either 0 or 1. Explosion level 0 defeats all dependency actions. Explosion level 1 touches objects that depend on objects which are recreated, renamed, moved, erased or destroyed. Explode levels greater than 0 rely on dependency tracking to be on in order to work. |
| New Keyword | This is a keyword assigned to all newly registered objects. It is a convenient way to keep track of which objects are new to your environment since you last reset this keyword. Throughout this document, this keyword is assumed to be the value “$new”. To reset the keyword so no objects are flagged as new, enter
ZOMSet +k $new ;k! $new |
| Changed Keyword | This is a keyword that is assigned to all objects which have an action applied to them which implies they have been changed in some way. These actions include such commands as ZOMCreate, ZOMReCreate, ZOMReName, ZOMMove, ZOMErase, ZOMDelete, ZOMCompile and ZOMUnCompile. It is a convenient way to keep track of which objects have been manipulated in your environment since you last reset this keyword. Throughout this document, this keyword is assumed to be the value “$changed”. To reset the keyword so no objects are flagged as changed, enter
ZOMSet +k $changed ;k! $changed |
| Environment Code | The Environment Code is used to co-ordinate multiple development environments in a team context. Refer to Team Development Projects and ZOM for more information about the environment code. If you are not coordinating programming teams or working at more than one development site, this field can be left blank. ZOM randomizes an environment code for you. |
| Express Mode | Certain operations such as ZOMExport can operate in either a set-oriented fashion (express mode is on) or a record-at-a-time fashion. In the former, the command performs more quickly. However, you do not see a separate status displayed for each object as it is processed nor is a separate log entry made for each object. This information is available when express mode is off. |
