Using the Oracle Forms Migration Assistant

Oracle Forms provides a tool that updates obsolete usage in your PL/SQL code in order to migrate your Forms 6i applications to Oracle Forms. The tool issues warnings when it cannot make the required changes automatically. This tool has a command line and a wizard version.

This chapter contains the following sections:

Go to http://otn.oracle.com for the latest version of the tool.

What Does the Oracle Forms Migration Assistant Do?

The Oracle Forms Migration Assistant does the following for all Forms module types (including object libraries and PL/SQL libraries):

You run the Oracle Forms Migration Assistant in batch mode. You can re-enter the utility as needed to run the migration process on a Forms application more than once.

By editing the converter.properties file, you can set options before you start the batch migration. By editing the search_replace.properties file you can specify the strings that the Oracle Forms Migration Assistant will search for and replace, and edit the warnings that are issued when an obsolete Built-ins is encountered.

The tool creates a log file so that you can navigate to problem areas in the application and make modifications manually.

Mutiple Log Support

The Forms Migration Assistant allows you either to write all log information into a single log file or span mutiple log files. If the Forms Migration Assistant spans multiple log files, the Forms Migration Assistant generates individual log files for each module that is processed.

You'll need to specify the directory in which the Forms Migration Assistant writes the log files. The name of the log file which is generated is modulename_moduletype.log.

For example, if you process a module by name, such as test.fmb, the name of the log file is test_fmb.log. If you select test.fmb and test.mmb for migration, the Forms Migration Wizard does not overwrite the log files since the type of log file was specified in the converter.properties. The Forms Migration Assistant generates two log files: test_fmb.log and test_mmb.log.

Editing the converter.properties File

To change migration options, edit the converter.properties file in a text editor. You can set the following migration options:

Table 2-1 Oracle Forms Migration Assistant converter.properties File Options
Option Description

Log File Name (default.logfilename)

Specifies the file name and location for log information.

Reports Queue Table Installed (default.usequeuetables)

When using web-based reports, these queue tables can be used to monitor queued and processed reports. When used with the Oracle Forms Migration Assistant, the queue table provides detailed error messages when installed in the application schema. (For example, if a report cannot run due to uncompiled PL/SQL, you can use the queue table to query for full error messages.) The resulting report is automatically printed. See the Reports Services documentation for more information about the Reports Queue Table.

Reports Servlet Directory (default.servletdir)

Specifies the name that has been defined for the virtual path used for the Reports Servlet, which is used for running reports on the web. This setting is required when converting Run_Product calls to Run_Report_Object.

Reports Servlet Name (default.servletname)

Specifies the name for the Reports Servlet used for running reports on the web. This setting is required when converting Run_Product calls to Run_Report_Object.

Reports Server Host (default.reports_servername)

The name or IP address of the machine running the Reports Server. This setting is required when converting Run_Product calls to Run_Report_Object.

DESTYPE (default.destype)

The type of destination device that will receive the report output. See the Reports Developer Reference for details.

DESFORMAT (default.desformat)

The printer driver to be used when DESTYPE is FILE. See the Reports Developer Reference for details.

DESNAME (default.desname)

The name of the file, printer, e-mail ID, or distribution list to which the report output will be sent. See the Reports Developer Reference for details.

Reports Server Host (default.reportshost)

The name or IP address of the machine running the Reports Server. This setting is required when converting Run_Product calls to Run_Report_Object.

Editing the search_replace.properties File

The search_replace.properties file contains the strings that the Oracle Forms Migration Assistant will search for and replace. It also contains a list of obsolete Built-ins that will generate warnings.

Adding Search-and-Replace Strings

You can edit this file to add your own search-and-replace strings, as follows:

  1. Open the search_replace.properties file in a text editor.

  2. Go to the end of the list of search-and replace strings.

  3. Add a string to search for and replace using the following syntax:

    SearchString|ReplaceString
    
    
  4. Save the search_replace.properties file.

    Note: Do not delete the last two commands in the search_replace.properties file. See the release notes for more information.

Modifying Warnings for Obsolete Built-Ins

The warnings for Built-ins have the following syntax:

<class>.Message=<WarningMessage>
<class>.Warning1=<BuiltIn1>
<class>.Warning2=<BuiltIn2>
<class>.Warning3=<BuiltIn3>
etc.

For example, for the class obsoleteMenuParam, the warnings are coded as follows:

obsoleteMenuParam.Message=Menu Parameters are no longer supported, the parameter 
and usage of %s should be replaced using a Forms parameter or global variable.
obsoleteMenuParam.Warning1=MENU_PARAMETER
obsoleteMenuParam.Warning2=QUERY_PARAMETER
obsoleteMenuParam.Warning3=TERMINATE

<class> is a group of Built-ins that have a common warning. <WarningMessage> can contain one variable string (%s).

When the Oracle Forms Migration Assistant finds a Built-in for which a warning should be issued, it logs the warning and replaces the variable string (%s) with the Built-in name.

Classes that have already been created in the search_replace.properties file are:

You can add more Built-in warnings to an existing class, or create new classes and warnings:

  1. Open the search_replace.properties file in a text editor.

  2. Go to the end of the list of warning messages.

  3. Add a warning to an existing class or create new classes and warnings using the syntax described above.

  4. Save the search_replace.properties file.

    Note: Do not delete the last two commands in the search_replace.properties file. See the release notes for more information.

Starting the Oracle Forms Migration Assistant

You should upgrade the common modules (such as OLB files) and Libraries (PLL files) that a Form relies upon and ensure that these are available in the FORMS90_PATH, before running the migration assistant.


Note:

For UNIX, an xterm display is required to run the Oracle Forms Migration Assistant.



Note:

The forms90\rp2rro.pll and forms90\EnableDisableItem.pll files should be in the FORMS90_PATH in order to convert RUN_PRODUCT to RUN_REPORT_OBJECT.



Note:

In UNIX, set the variable FORMS90_PATH, such as
setenv FORMS90_PATH $Oracle_Home/forms90


To start the Oracle Forms Migration Assistant on Windows, enter:


ifplsqlconv90 mode=batch module=<modulename> log=<log>

To start the Oracle Forms Migration Assistant on UNIX, enter:

f90plsqlconv mode=batch module=<modulename> log=<log>

You can also specify additional command line parameters, as described in Table 2-2, "Oracle Forms Migration Assistant Command Line Parameters":

Table 2-2 Oracle Forms Migration Assistant Command Line Parameters
Parameter Description

modulename (required)

Specifies the module to migrate. The modulename parameter can take only one value. See "About the Migration Assistant in Batch Mode" if you want to migrate more than one file at a time.

log (optional)

Specifies the log file to which the migration results are written. If not specified, the default values from the converter.properties file are used.

Mode (optional)

This option has two values (batch and wizard). Use mode=batch to run Converter in Batch mode.

Information about the progress of the migration process is displayed on the screen. It is also saved to the log file that you specify in the converter.properties file. (To change migration options, see Editing the converter.properties File.)

Check the log file for information about required migration steps that the tool did not modify. Manually make these changes to your application.

About the Migration Assistant in Batch Mode

You can convert multiple applications by running the Forms Migration Assistant in batch mode from the command line. Batch mode is useful for converting multiple Forms applications. For example, on Windows NT, create a batch file (for example upgrade.bat) that contains the following:

for %%ff in (%1) do call ifplsqlconv90 module=%%ff

Then run the batch file as follows:

upgrade *.fmb

or

upgrade foo*.mmb

On UNIX, create a shell script (for example upgrade.sh) that contains the following:

for file in $*
do
   f90plsqlconv.sh module=$ff
done

Then run the shell script as follows:

upgrade.sh *.fmb

or

upgrade.sh foo*.mmb

Starting the Migration Assistant in Batch Mode

To start the Migration Assistant in batch mode in Windows:

ifplsqlconv90 mode=batch module=<filename> log=<logname> 

To start the Migration Assistant in batch mode in UNIX:

f90plsqlconv  mode=batch module=<filename> log=<logname> 

where <filename> is the name of the file you want to convert, and <logname> is the name of the log file that will get generated.

In the following example:

ifplsqlconv90 mode=batch module=d:\temp\test.fmb log=d:\temp\test.log

Forms Migration Assistant will look for the file "test.fmb" in the d:\temp directory and will name the generated log file "test.log" and place it in the d:\temp directory. You can give the log file any name you want and specify any location you want. By default the log file is written in $ORACLE_HOME\bin. The module parameter can take only one value.

The output of the conversion is displayed on the screen. It is also saved to the default log file. Note that in batch mode, all converter options are taken from the converter.properties file. To change the converter options, see "Editing the converter.properties File".
