Export an Individual Component

In Workbench you can export an individual component from the Develop tab. You can save the file in text or XML format.

1. Select the application containing the component to export in the Applications portlet of the Develop tab.

2. Select the component to be exported in the Components portlet.

See the descriptions for each of these parameters in Parameters for the ExportComp Utility.

Note: You can set defaults for this utility using the Set Tool Defaults dialog. see Set Defaults.

You can specify the following parameters using the Export a Component dialog:

Specifies the format of the file to be exported:

Specifies whether metadata (AlterBy, AlterDate, Creator, CreateDate) should be exported with the component. If this parameter is not set, OpenROAD assigns no metadata to the exported component. To use this parameter, you must also specify XML as the file input format.

Specifies the path and name of the file (.exp or .xml) to which the component is being exported. By default, the name of the component is provided; overwrite this to change it. Click Browse to display a standard File Selection dialog so that you can save the file to a different location.

Lets you use this command as if you were another user, username.

Note: You, not username, own all files created by OpenROAD.

Specifies the name of a log file. This entry field can be used only if Execute in Background is enabled and Trace Window is set to Yes. If the log path specified is not a full path, the file is created in the ingres\files directory.

Lets you control display of the Trace window by entering one of the following values:

Specifies that the Trace window appears but suppresses informational messages output by the system

Specifies that the Trace window appears minimized as an icon

Specifies that the Trace window does not appear, and a log file is not created

Note: This entry field can be used only if Execute in Background is enabled.

Appends the trace output of the current command to the end of the existing error log file. Otherwise, that log file is replaced. This entry field can be used only if Execute in Background is enabled.

Note: The error log file, w4gl.log, is located in %USERPROFILE%\AppData\Local\OpenROAD\Profiles\installation_ID. If the -L flag is passed, a new name and location can be provided for the OpenROAD log file.

Begins a new process while you are using this utility.

If enabled, Execute in Background makes Username, Log Path, Trace Window, and Append to Log File available for use.

Note: You can set defaults for this utility using the Set Tool Defaults dialog. see Set Defaults.

Command Line Method of Exporting Components to a File (BackupApp)

To export a component to a file, start the BackupApp utility from the command line:

w4gldev backupapp out database application file [-nowindows]

[-ccomponent | -l [-xml [-xmeta]] [-uusername] [-Lfilename] [-vversion]

[-T{yes|yes,min|yes,logonly|all|all,min|all,logonly|no}] [-A] [-t]

For more information about including default attribute values and indenting XML elements when exporting, see Effect on File Size of Including Default Attribute Values and Indenting XML Elements.

The following parameters and flags are available from the command prompt:

Specifies the export mode of the BackupApp utility

Specifies the name and location of the database in which the application resides

Specifies the name of the application from which the component is being exported

Specifies the name of the file to which the component is being exported (.exp or .xml)

Lets the application run without the window manager running. This option does not provide full batch mode execution, because some interaction with the application still may be required through the Trace window.

Specifies the name of the component to be exported

Directs the BackupApp utility to treat the file parameter as the name of a file containing a list of component name and component source file pairings (separated by a comma)

Specifies XML format

Specifies whether the original XML metadata (AlterBy, AlterDate, Creator, CreateDate) is exported to the XML component file. If this parameter is not included, OpenROAD assigns new metadata to the exported component. To use this parameter, you must also specify -xml as the file input format.

Lets you use this command as if you were another user, username.

Note: You, not username, own all files created by OpenROAD.

Specifies the name of a log file. If the log path specified is not a full path, the file is created in the %II_SYSTEM%\ingres\files directory.

Specifies the version of the component to export

Controls the display of the Trace window by entering one of the following values:

Specifies that the Trace window appears but suppresses all informational system messages

Specifies that the Trace window appears minimized as an icon, and all informational system messages are suppressed

Specifies that the Trace window does not appear, but all messages are saved in a log file without informational system messages

Specifies that the Trace window does appear and all messages are written

Specifies that messages are written to the Trace window, which appears minimized as an icon

Specifies that the Trace window does not appear, but all messages are saved in a log file

Specifies that the Trace window does not appear, and no log file is created

Appends the trace output of the current command to the end of the existing error log file.

Note: The error log file, w4gl.log, is located in %II_SYSTEM%\ingres\files.

Specifies that transactions are committed after each component is exported from the database

IMPORTANT! Using this parameter decreases contention and log file use. However, if your database server terminates abnormally or the utility is aborted before completion, only some of the application components are exported.

An exit code of zero (0) means success; a non-zero exit code indicates an error.

The following example exports a component, “comp1” from application “myapp” in the database “mydatabase,” in OpenROAD text format to the export file “comp1.exp”:

The following example exports a component, “comp2” from application “myapp,” in XML format to the export file “mycomp.xml.” Metadata is not included in the file:

w4gldev backupapp out mydatabase myapp mycomp.xml -ccomp2 -xml

The following example exports a component, “comp3” from application “myapp,” to the export file “mycomp.xml.” Metadata is included in the mcomp.xml file:

w4gldev backupapp out mydatabase myapp mycomp.xml -ccomp3 -xml -xmeta

The following example exports the component source files and comma-separated component name and component source file pairings in the file “comps.lst”:

This will export three components from the application “myapp” (in database “mydatabase”) into the following export files:

• “helloworld” is exported into the file “hw.exp”
