We can reduce this download time by keeping a copy of these files on client side prior to accessing the application. If we place these file on the default CLASSPATH of JRE , JRE use these files form client side instead of downloading it from server. Suppose JRE is  installed  in C: drive, you can place these files in following directory,

C:\Program Files\Java\jre6\lib\ext

Now when you access Forms 11g application, JRE loads all required JAR files from  \ext directory.  This saves significant time on a slow connection.

In oracle Forms this key mapping is defined in fmrweb.res file. Oracle provided a tool named “Oracle Terminal” in Forms 6i to customize key mapping. In Forms 10g and Forms 11g this file is directly editable.  In Forms 11g this file can be located at following location

$Instance_home\config\FormsComponent\forms

In Forms 10, frmweb.res can be located in \forms directory

As you know, in Forms 10g and 11g “List of values” is mapped to “Ctrl+L” key. Following section explains how to change “List of values” to F9 key. Let have a look at the following line in frmweb.res file which maps “List of values”  to “Ctrl+L” key

76   : 2 : “Ctrl+L”         : 29 : “List of Values”

it very important to understand the syntax.

76: is the key code of  “L” character

2: means that it will be accessed with “Ctrl” key, 1 is used for “Shift” key and  0 is used to access it stand alone

Ctrl+L: it is the key used to access

List of values: it is function called when the “Ctrl+L” is type

To re-map List of values from “Ctrl+L” to F9 key, we need key code of F9 key which is 120. A complete list of key codes can be view at following link

Keyboard keys and Key Values

Now edit key mapping for  List of values as under

120  : 0 : “F9″             : 29 : “List of Values”

To test it, restart your forms application. Now List of values is available with F9 key. similarly if you want to use “Shift+F”  for List of values, use following mapping

120  : 1 : “Shift+F9″             : 29 : “List of Values”

and use following mapping to access List of values with “Ctrl+F9″

120  : 2 : “Ctrl+F9″             : 29 : “List of Values”

Web.Show_Document('http://domainname.com:8090/reports/rwservlet?userid=username/password@db& server=ReportsServer_1&desformat=PDF&destype=cache&report=report.rdf&paramform=yes','_blank');

In above call username and password are visible in URL, causing security problem. Oracle has provieded serveral methods to resolve this problem, one of these solution is to define keymapping in CGICMD.DAT file.  In Reports services 11g this file is located at following location

$DOMAIN_HOME/servers/WLS_REPORTS/stage/reports/reports/configuration/cgicmd.dat

In Oracle Reports services 10g this file can be located in  \reports\conf directory.

To define a key mapping, append follwing line at the end of  the file

userlogin:      userid=username/password@db  %*

Restart reports server/Managed server, now you can call your report using following URL

Web.Show_Document('http://domainname.com:8090/reports/rwservlet?userlogin&server=ReportsServer_1&desformat=PDF&destype=cache&report=report.rdf&paramform=yes','_blank');

You can define key mapping for as many parameter as you need using following syntax,

userlogin:      userid=username/password@db server=ReportsServer_1 desformat=PDF destype=cache %*

# Parameter related to the version of the Java Plugin
jpi_mimetype=application/x-java-applet;jpi-version=1.6.0_12

Note that forms services is configured with  JRE 1.6 update 12.

Each time Firefox  tries to load java applet, it looks for  java version 1.6.0_12. If your system has other version installed then you get following message,

Additional Plugins are required to display all the media on this page

To resolve this problem either install JRE 1.6 update 12 or edit you FORMSWEB.CFG to omit the java plugin as under

# Parameter related to the version of the Java Plugin
jpi_mimetype=application/x-java-applet

Now as FORMSWEB.CFG do not include any specific version java, Firefox will load java applet with any available java plugin.

Note that, there is no such issue with Internet Explorer.

In case of OID, you can install either Oracle Internet Directory 11g or Oracle Internet Directory 10g (10.1.4.3.0). As Oracle Fusion Middleware has no Single sign-on, so you must install single Sign-on version 10g (10.1.4.0) with Delegated Administration services.

If you want to use OID 11g you can install it with Oracle Database 11g (11.1.0.7.0) or Oracle Database 10g (10.2.0.4). For OID 10g you should use Oracle Database 10g (10.2.0.4). Although OID 10g(10.1.4.3.0) can be installed on 10.1.0.5 or higher version but Portal 11g and Discover 11g repositories support only Oracle Database 10g (10.2.0.4) or oracle Database 11g (11.1.0.7.0).

Weblogic server is required for Oracle Internet Directory 11g and for Forms, Reports, Portal and Discoverer 11g.

If you have decided to proceed with Oracle Internet Directory 11g, visit following links to view step by step installation guide,

Create a directory as  C:\myapp
Now create an HTML file named  “MY.HTML” and place it in C:\myapp directory.
Now locate the file weblogic.xml in following directory

$DOMAIN_HOME\servers\WLS_FORMS\stage\formsapp\11.1.1\formsapp\formsweb.war\WEB-INF\

Now add following line to  weblogic.xml file

<virtual-directory-mapping>
<local-path>C:\myapp</local-path>
<url-pattern>myapp/*</url-pattern>
</virtual-directory-mapping>

Now open  Forms.conf file which can be located at following location

$ORACLE_INSTANCE\config\OHS\ohs1\moduleconf

Add following two line in this file

AliasMatch ^/forms/myapp/(..*) “C:\myapp/$1″
WLExcludePathOrMimeType /forms/mypp/

Now Restart HTTP server and open following URL

Http://localhost:8090/forms/myapp/my.html

If page is displayed, virtual mapping is successful.

Note that virtual mapping for Forms 11.1.1.2 is not supported in this way.

Deploy Images and Icons in Forms 11g

Similarly mapped virtual directory can be used to deploy icons and images. To deploy icons or images do following.

Add icons/images to a JAR file using following command

<Oracle Home>\jdk\bin\jar –cvf myAppIcons.jar *.gif

Now place this myAppIcons.jar file to c:\myapp directory .
Now modify formsweb.cfg file by adding following bold face words,

archive=frmall.jar,/forms/myapp/myAppIcons.jar
imageBase=codebase

This JAR file can also be places in a pre-mapped directory like  $ORACLE_HOME\forms\java.
If you do not want to create JAR files of icons, you can directly place your icons in  $ORACLE_HOME\forms\java directory

Oracle database creates server processes to mange requests of user process. All user process issues SQL statements, it is the responsibility of Server process to execute these statements and return results to user process. Each server process has one PGA. PGA is memory where server process executes statements and stores information. PGA consists of Private SQL Area, session memory and SQL work Areas.

Each statement in oracle is associated with a Private SQL area. Private SQL area can be divided into persistent area and run-time area. Persistent area contains bind information, i.e. the values for bind variables. Runtime area is used to execute the statements. Private SQL area is created in PGA if the connection is established using dedicated server. In case of shard server connection, Private SQL area is created in SGA.

PGA also contains Session Memory which is used to store session information for example session variables and logon information.

Few queries require complex operation like Hash Join or sorting. These operations are performed in the memory. To perform these tasks, SQL work areas are created in runtime area. The size of SQL work areas should be large enough that it can contain  data accessed by SQL statements. If size of work area is not large enough then response time may increase and hurt database performance. Oracle supports automatic memory management of work areas. Automatic management involve to steps, first you decide maximum memory available for PAG. Then use PGA_AGGREGATE_TARGET initialization parameter to set maximum memory available for PGA. This will only work for dedicated server mode. Because in shared servers, SQL work areas are created in SGA.

ORA-02248: invalid option for ALTER SESSION

To resolve this problem simply upgrade your Developer 6i release by applying a patch or by fresh installation. For example, when I first time encountered this problem, I was using Forms Builder 6.0.5.0.2. I removed my previous release and installed Developer release 6.0.8.8.0. After up-gradation I was able to connect to 11g server without further problem.

When I first time tried to run my form, Forms Builder 6.0.8.8.0 asked me to re-enter password. This is because 11g has new Case sensitive password feature. When I first time connected to Forms Builder, I supplied correct password which was in lower case. When I tried to run form, Forms Builder tried to connect to 11g server with upper case user and upper case password. This is default behavior of Forms builder. Similar problem occurred when I tried to call reports from Forms using RUN_PRODUCT() method. To resolve this problem either set database users passwords to upper case or issue following SQL command to disable case Sensitive password feature.

ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE;

Upgrading your Developer release will resolve you problem but you must remember that developer 6i with 11g is not a supported combination by oracle as support for Developer 6i has been dis-continued. Oracle recommends upgrading you developer to latest version like Oracle Developer Suite 10g or Forms 11g.

http://exploreoracle.com/2009/09/06/rman-script-to-take-full-database-backup/

Now we have scenario in which all data files have lost, we have also lost controlfiles. But some how, we haven’t lost archivelog files since last backup. In this case, we can recover our database using RMAN backup and archivelog files. We shall only lose data which was in current online redo log file. Remember, at startup our database in not opened.

Invoke RMAN and connect to database using following command.

RMAN> connect target /

Now set DBID with following command, it should be the Id of your database.

RMAN> set dbid=1216018526

Now start database in nomount stage.

RMAN> startup nomount;

Now configure controlfile autoback location.

RMAN> set controlfile autobackup format for device type disk to 'd:/rmanbackup/%F’;

Use following command to restore controlfiles.

RMAN> restore controlfile from autobackup;

Using this way all three control files will be restored to their default locations. However, there is another way to restore controlfile if you do not want to restore controlfile using “from autobackup”.  In this method,  first connect to database, and then start it in nomount stage.  Now locate the file name  which contains controlfile backup in d:\rmanbackup,  copy its  name.  Now issues following command to restore control file

RMAN> restore controlfile to ‘c:/CONTROL01.CTL’ from  ‘d:/rmanbackup/C-1216018526-20090905-00′;

In this command  ‘C-1216018526-20090905-00′ is name of backup file which contains controlfile backup. This file can be from autobackup or from  other backup. Other back means controlfile backup taken using “backup format” method in RMAN.

Above restore controlfile  command will create only one controlfile at ‘c:/CONTROL01.CTL’. Now copy this first control file at its location and save as it two times to create CONTROL02.CTL, and CONTROL03.CTL files.  using this method you do not need to set DBID, and autobackup control file location.

Restoration of control file is key point in database recovery. As control file has the information about all datafiles. Once control file is restored, database can be mounted.  Mounting of database is necessary.  All recovery operation can only be performed in mount stage. You can mount your database using following command.

RMAN> mount database;

After mounting database, this is time to restore all datafilese. To restore database, use following command.

RMAN> restore database using tag full_db;

Media Recovery should be performed on database before opening. In this step archivelogs are applied to recover data since last backup and to bring database in consistent stage.

RMAN> recover database;

Issue following command to open database and reset logs

RMAN> alter database open resetlogs;

Following snapshots show full recovery process.
