|Oracle® Application Server Release Notes
10g Release 2 (10.1.2) for IBM zSeries Based Linux
This chapter describes issues associated with Oracle Forms. It includes the following topics:
This section describes general issues and workarounds. It includes the following topics:
Using a dual monitor configuration with Oracle Forms is now supported.
On Unix platforms, if you relink Forms executables after installation (for example, because you are applying a one-off patch) the permissions on newly created executables will not necessarily be the same as the originals. Use
chmod to change them manually.
Forms applications use Oracle Application Server Single Sign-On only for obtaining database connection authentication. Once this connection is made, interaction with Oracle Application Server Single Sign-On no longer occurs. Exiting a Forms application will not perform an Oracle Application Server Single Sign-On logout. Conversely, logging out of an Oracle Application Server Single Sign-On session will not terminate an active Forms session. The database session will exist until the Forms Runtime (e.g. frmweb.exe) on the server terminates, usually by explicitly exiting the form.
On SLES9, when you click the Forms link on the Enterprise Manager main page, the Forms Overview page is displayed. On this page, the Pie Chart showing the Memory Usage is broken and shows an unhandled exception error. When you click the User Sessions tab, it shows the Total Memory Usage, in percentage. Due to the way SLES9 operating system reports the memory of a process, the private and shared memory sections display very high values. To resolve this issue, apply the following patch:
This section describes configuration issues and their workarounds. It includes the following topics:
The EM_MODE parameter in
formsweb.cfg needs to be set to
1 for Grid Control to collect metrics. This parameter is set to
0 by default. You will need to restart the Enterprise Manager Agent.
After disabling Web Cache, Grid Control reports Forms targets as down, which is false. As a workaround, in the
targets.xml file in
%ORACLE_HOME%/sysman/emd, change the target property with the
NAME="ServletUrl" to read from the HTTP listener port instead of the Web Cache port.
If you encounter a FORBIDDEN error when using One-Button-Run with any of the supported Browsers other than Internet Explorer, verify if 127.0.0.1 (localhost) is in the proxy settings for your browser. If 127.0.0.1 is not in the exceptions list, then add it. This ensures that the browser will bypass the proxy server.
The environment setting FORMS_RESTRICT_ENTER_QUERY has a default value of
TRUE. This setting disallows users from using QUERY-WHERE functionality until it is set to
With Oracle Forms 10.1.2 and higher, the Forms PJC Wizard is part of the standard Forms installation. The PJC Wizard works with JDeveloper 10g (10.1.2) that is part of Oracle Developer Suite 10g. For versions of JDeveloper that are obtained from OTN, the PJC wizard is available as a separate Jar file to download and place into your JDeveloper installation.
In CJK languages, the Forms client may stop responding when clicking another item while inputting text through inline IME. As a workaround, disable the inline IME. See section 4.10.2, "Inline IME Support" in Oracle Application Server Forms Services Deployment Guide. This issue will be fixed in a future patch set.
The Install JDK 1.4.2 dialog appears when running a Form on the Web for the first time. When you click Install, the JDK 1.4.2 Plug-in is installed instead of the JDK 1.4.2_06 Plug-in. If you are attempting to use the JDK 1.4.2 plugin from Internet Explorer, and it is not currently installed on your machine, it will download the wrong version. The workarounds are:
formsweb.cfg by finding:
and change it to:
Run the Form (for the first time) from Netscape, which will go to the correct location for the download.
Go to the correct location and manually install the JDK 1.4.2_06 Plug-in.
When using Japanese NLS_LANG (JA16SJIS, JA16EUC etc.) if the queried CLOB data is longer than the maximum length (240 bytes by default) of the Text Item corresponding to this CLOB data, the query fails at runtime. The issue is that the CLOB data is correctly truncated with the maximum length of the Text Item (240 bytes by default) in English NLS_LANG, but not in Japanese NLS_LANG.
This issue may also raise error message
"FRM-92101" depending on your platform.
As a workaround, extend the maximum length of the Text Item to fit the length of the CLOB data.
The FRM-92102 error appears and existing Forms sessions disconnect after adding a new user to JAZN (OC4J_BI_FORMS | Applications | formsapp | Security). Thus, if you're adding new JAZN users to the OC4J_BI_Forms instance, you should do this while no Forms session is running.
On the System Component Tables in Enterprise Manager, the CPU and Memory statistics are collected every minute, by default. Note that this potentially can mean that any CPU spikes will not be displayed. In addition, if Forms server processes are dormant, awaiting client activity or requests, it is perfectly normal for the CPU usage to report 0.0%.
On the Forms Overview page, the CPU and Memory statistics are gathered each time the page is rendered when you click the Overview Tab or when you click the refresh icon next to the timestamp. However, due to an operating system restriction, if the Response Time from the Forms Servlet is less than 16ms, it will display as 0.00ms.
This section describes documentation errata. It includes the following topics:
In the topic "About Converting Modules from Binary to Text Format", it states:
"The text version of a module is a human-readable file that describes its objects and code."
It should read:
"The text version of a module is a human-readable file that describes its objects and PL/SQL code translated into hex."
The FIXED_LENGTH property, as mentioned in the online help, is obsolete. It is mentioned as a property of the SET_ITEM_PROPERTY Built-in, and in the PL/SQL and Forms Reserved Words.
In the Oracle Forms Services Deployment Guide, the following parameters are invalid:
In Oracle® Forms Migrating Forms Applications From Forms 6i 10g (10.1.2.0.2) for Windows and UNIX, in Chapter 2, Using the Oracle Forms Migration Assistant, the sample UNIX script says:
for file in $* do frmplsqlconv.sh module=$ff done
This small script does not work in Unix. The corrected script is:
for file in $* do frmplsqlconv.sh module=$file done
In Chapter 6, the section titled "Enabling OracleAS Single Sign-On for an Application" describes correctly the steps to add this parameter to the configuration section of a chosen application. However, if you change an existing section such as the default, the steps are slightly different as the parameter already exists.In this case, Step 5 becomes is where you select the parameter and enter a new value.
In Section 18.104.22.168.1 of Oracle Application Server Forms Services Deployment Guide, the description for Mapping F2 is written as:
To map F2, change the default entry for F2, "List Tab Pages", to another key. Here is an example of the default entry:
113: 0 : "F2" : 95 : "List Tab Pages"
This must be explicitly changed to another key mapping such as the following:
113: 8 : "F2" : 95 : "List Tab Pages"
The last line should read as:
113: 8 : "Alt+F2" : 95 : "List Tab Pages"
In section 7.5.12 of Oracle Application Server Forms Services Deployment Guide, there is a sample formsweb.cfg configuration. The last named section is written as:
[salesApp] form=sales.fmx userid=sales/salespw@orcl
However, this example should read as:
[salesApp] form=sales.fmx userid=sales/salespw@orcl jvmcontroller=
In section 9.2.2 of Oracle Application Server Forms Services Deployment Guide, the script tag is written as:
It should read as:
In section 9.2.5 of Oracle Application Server Forms Services Deployment Guide, the default threshold description is written as:
The default unreasonable threshold is set to 60,000 milliseconds, which may be too small for Oracle Forms Applications. You may want to change this default to 1 minute.
The correct description should read:
The default unreasonable threshold is set to 60,000 milliseconds, which may be too small for Oracle Forms Applications. You may want to change this default to 1 hour.
In section 9.3.1 of Oracle Application Server Forms Services Deployment Guide, the
EndUserMonitoringURL parameter is written as:
It should read as:
EndUserMonitoringURL=http://<hostname>:<webcache port number>/oracle_smp_chronos/oracle_smp_chronos_sdk.gif
Without the correct
EndUserMonitoringURL parameters, End User Monitoring will not work.
Oracle Application Server Forms and Reports Services Installation Guide does not include the kernel parameters for OracleAS Metadata Repository.
For the correct list of these kernel parameters and the procedure to set them, refer to "Section 4.4.2 Kernel Parameter Settings for OracleAS Metadata Repository" in Oracle Application Server Installation Guide.
