Oracle Forms 12c (12.2.1) first impressions

As I already posted over the weekend, several new Oracle Fusion Middleware Components were released by Oracle.

One of this new Components is Oracle Forms & Reports 12c (12.2.1).

I have been playing around a little bit with the latest release:

  • Oracle Forms & Reports 12c is now requiring a configured Meta Repository
  • Don't try to use as the underlying Oracle WebLogic Server 12c (12.2.1) the "standalone" WebLogic Server, you NEED to install the Fusion Middleware Infrastructure Option (1.4 GB download) or else you can not install the Forms & Reports Part on top of your WebLogic/Infrastructure
  • The new Enterprise Manager is really cool now :-) can be reached under http://yourserver:port/em

The Look'n Feel is completely redesigned, my personal feeling is that the Oracle ALTA UI from Oracle ADF was the base for this really cool redesign.

APEX 5.0 available for download

Since yesterday (15th April 2015) the latest Oracle Application Express (APEX) release 5.0 is available for download.

APEX 5.0 can be found under

The new APEX 5.0 is supported for all Editions of Oracle Database or higher, even Oracle Express Edition 11g (XE) can be used for the new APEX 5.0

OBIEE automatic redirect to a Dashboard via mod_rewrite

Normally end users would like to have a simple URL access for Oracle Business Intelligence Enterprise Edition (OBIEE) 11g like http://webhost:7777 and than to be automatically redirected to their Dashboard, instead of typing endless complex URL's.

Assuming you have following standard implementation of an OBIEE environment which contains an Oracle HTTP Server (OHS) configured with mod_wl_ohs to be proxied to point to your WebLogic Server hosting OBIEE and an OBIEE Server, you can simply use the available OHS module mod_rewrite.

In the following I will use the within OBIEE delivered "OBIEE SampleApp Lite" application to demonstrate how to configure the redirect to a specific Dashboard.
By default after login to OBIEE you will be directed to the "bieehome" (see imagine below).

That's quite ok for testing proposes, but the classical end user wants to be pointed normally to another Dashbord, e.g. the "QuickStart / Readme" out of the "OBIEE SampleApp Lite" application (see imagine below).

By looking into the URL for the above displayed "QuickStart / Readme" Dashboard, we can easily see that the URL is containing several HMTL URL Encodings (for a full reference of HTML URL Encoding see which are red marked:


Mostly we will find HTML URL Encodings like %2F (= forward slash) and %20 (= white space). As I was working in the past intensively with mod_rewrite, I know that such special characters within mod_rewrite rules brings you a lot of pains.

My first starting point was a usual to consult the mod_rewrite documentation ( and checking the various special flags for CondPattern like NE (noescape) and so on, playing around with RegExp. After multiple failed tests, I was thinking, why not to use the KISS approach :-)

Take from the above URL pointing directly to the "QuickStart / Readme" Dashboard all HTML URL Encodings. In this case four times %2F (= forward slash) and one time %20 (= white space) and replacing the HTML URL Encodings with the "real values" and placing them in my mod_rewrite rule as a double-quoted string:

Check in your httpd.conf that the mod_rewrite module is loaded:

LoadModule rewrite_module "${ORACLE_HOME}/ohs/modules/"

Add at the end of your httpd.conf the following 2 lines. First line is turning your RewriteEngine on and the second line defines your mod_rewrite rule, that all requests to http://webhost:7777 should be redirected to "/analytics/saw.dll?Dashboard&PortalPath=%2Fshared%2FSample%20Lite%2F_portal%2FQuickStart&page=Readme", but with the replacement of the real values of the HTML URL Encodings:

RewriteEngine on
RewriteRule   ^/$  "/analytics/saw.dll?Dashboard&PortalPath=/shared/Sample Lite/_portal/QuickStart&page=Readme"  [R]

Save your httpd.conf and restart your OHS server. Now when an end user is accessing the URL http://webhost:7777 he will be automatically redirected to http://webhost:7777/analytics/saw.dll?Dashboard&PortalPath=%2Fshared%2FSample%20Lite%2F_portal%2FQuickStart&page=Readme

Some times its really good to give even "unconventional" solutions a chance :-)

Startup or Shutdown of multiple WebLogic Managed Servers via WLST script

Normally you will have multiple Managed Servers within one WebLogic Server Domain. The classical approach to startup or shutdown these multiple Managed Servers are:

  • using the WebLogic Server provided scripts startManagedWebLogic.[sh|cmd] and stopManagedWebLogic.[sh|cmd] in your Domain Directory
  • using a WLST script with the command shutdown()
The first option by using the startManagedWebLogic.[sh|cmd] and stopManagedWebLogic.[sh|cmd] requires that you provide the name of the Managed Server and the AdminURL, which is not quite flexible.   The second option has a small disadvantage in case you run the command shutdown() against a Managed Server which is currently not running. You will receive error messages like:
weblogic.server.ServerLifecycleException: Can not get to the relevant ServerRuntimeMBean for server DemoManaged

Specially when you are trying to shutdown multiple Managed Servers within such a WLST script that uses the command shutdown(), if you hit such an error the WLST script will terminate and the potential following shutdown() commands for other Managed Servers will not be executed.

With below WLST script, you can avoid this problem and perform your startup or shutdown tasks in a more elegant way.

The WLST script is using a properties file, in my case named which contains following:


The property serverlist is containing a comma seperated list of Managed Servers which you want to control.

The WLST script is moreover using an input value (start or stop). Before performing either the start() or the shutdown() command, the script will check for the MBean ServerRuntimeMBean if its existing or not for the given Managed Server.

import getopt
# Load the properties file with all necessary values
# Split the provided Server List String for the FOR LOOP in start and stop command
# Get the command, must be 'start' or 'stop'

# Check the provided command
if getcommand != 'start' and getcommand != 'stop':
  print 'usage: <start stop="stop">'

# Connect to the Weblogic Admin Server
# Connection Details are retrieved from properties file
connect(adminusername, adminpassword, adminurl)

# Change to the root of the MBean hierarchy

# Start Block
if getcommand == 'start':
   # Loop over the splitted Server List string
   for s in serverlistSplit:
     # Is a ServerRuntime MBean existing for current Managed Server?
     # If yes, the current Managed Server is already running and we dont need to do anything
     bean = getMBean('ServerRuntimes/' + s)
     if bean:
       print 'Server ' + s + ' is ' + bean.getState()
       start(s, 'Server', block='false')
       print 'Started Server ' + s

# Stop Block
if getcommand == 'stop':
   # Loop over the splitted Server List string
   for s in serverlistSplit:
     # Is a ServerRuntime MBean existing for current Managed Server?
     # If no, the current Managed Server is already down and we dont need to do anything
     bean = getMBean('ServerRuntimes/' + s)
     if bean:
       shutdown(s, 'Server')
       print 'Stopped Server ' + s
       print 'Server ' + s + ' is not running'


Place the properties file and the WLST script in one directory, adjust the properties file to your landscape.

To call the WLST script just source the required script setWLSEnv.[sh|cmd] out of your WLS_HOME/server/bin directory and then execute following command:

java weblogic.WLST [start|stop]

asmcmd non-interactive commands in MS-DOS Batches

In the last days I was fighting with a nice behaviour of the asmcmd non-interactive mode in MS-DOS batches.

I wanted to delete several files located in ASM within a MS-DOS batch:

REM Script: asm_cleanup_DB112.cmd
set ORACLE_BASE=E:\oracle
set ORACLE_HOME=E:\oracle\product\grid-11.2.0
asmcmd rm -f +TEMP/db112/temp_01.dbf
asmcmd rm -f +TEMP/db112/temp_02.dbf
asmcmd rm -f +REDO1/db112/redog1m1.dbf
asmcmd rm -f +REDO1/db112/redog2m1.dbf
asmcmd rm -f +REDO1/db112/redog3m1.dbf
asmcmd rm -f +REDO1/db112/redog1m2.dbf
asmcmd rm -f +REDO1/db112/redog2m2.dbf
asmcmd rm -f +REDO1/db112/redog3m2.dbf
As soon as I run the batch, the first file got deleted, but then the batch execution stops without continuing the next steps :-( I try to place the files into Single-Quotes, into Double-Quotes, but nothing helps, after the first asmcmd command the batch execution stops ...
This behaviour even occurs with "ls" commands and so on.
Oracle Metalink search = 0
Oracle Technet Forums = 1 thread with the same problem, but no answer since more then 2 years
After a little playing and re-thinking, I only found following solution: Build a FOR Loop in my batch.
I just created a textfile with my files which I want to delete:
# Content of File asm_file_list.txt
Then I changed my batch to the FOR loop, which simple reads my above textfile with the list of my files to be delete and executed for each line the "asmcmd rm -f" command:
REM Script: asm_cleanup_DB112.cmd
set ORACLE_BASE=E:\oracle
set ORACLE_HOME=E:\oracle\product\grid-11.2.0
for /f %%a in (asm_file_list.txt) do ( 
asmcmd rm -f %%a

Run the batch again and be happy :-)

Long live Oracle Forms - New Statement of Direction

Oracle (Grant Ronald) published today (15th March 2012) an updated Statement of Direction for Oracle Forms and Reports.

The major statement within this Statement of Direction is:

Oracle has no plan to discontinue support of Oracle Forms. Furthermore, a new version of Forms, Oracle Forms 12c, is planned for delivery as a component of Oracle Fusion Middleware 12c.
Thats really a clear and positive statement from Oracle :-)

The complete Statement of Direction can be found under following link:

Lets wait for Oracle Forms & Reports 12c :-)

ASM-00203 and Windows 2008 R2

I was fighting right now with my favorite Operating System and ASM :-)

I just installed Oracle Grid Infrastructure on a standalone Windows 2008 R2 server (successfully) and wanted to stamp some disks with the tool asmtoolg.exe. After I started the asmtoolg from a command prompt, I receive immediately an error message:

ASM-00203: No valid devices found

Cool :-) Oracle Metalink brings back following result:

After a little bit playing, I found following solution:
Open your Windows Explorer, navigate to your %ORACLE_HOME%\bin and do a right-click on the tool asmtoolg.exe and chose the Option "Run as administrator" and be happy :-) Now I could run the asmtoolg.exe without any error messages.

I was logged in as a local administrator and the above error message came up for me, only after I used above method I could stamp my disks. I really love my favorite Operating System ...

Bye bye WebCache - Welcome Oracle Traffic Director

I am currently sitting here and listen to the WebCasts for the new Oracle WebLogic Server 12c Release.

Some highlights:

  • More then 200 new features
  • Java EE 6 fully profile certified
  • Seamless upgrades (let's see the reality :-) )
  • Introduction of Oracle Traffic Director
In my opinion one of the highlights is the introduction of the Oracle Traffic Director, which will be the replacement of the Oracle WebCache on Exalogic platforms. I will miss the WebCache, I really learnt over the years to love this tool ;-)
Oracle Traffic Directory will be officially supported only with Exalogic platforms, but also runable on 64bit OEL platforms ;-)

The downloads for the new Oracle WebLogic Server 12c ( should be available on Oracle Technology Network from the 5th of December 2011 going.

Note 2nd December 2011: There is also a Data Sheet for the new Oracle Traffic Director available

Why you should never create own objects under SYS

I got many times the request by developers to create objects under the SYS schema and my comment is normally "NO". Here is a nice showcase, why the creation of own objects under the SYS schema can become really dangerous:

conn / as sysdba
select count(*) from dba_objects where status = 'INVALID';
-- Now lets create a simple table named SYSTEM under the SYS schema
create table SYS.SYSTEM (id number);
Table created.
-- Now check for invalid objects again.
-- Note: I didnt do anything special after the creation of the table SYS.SYSTEM
select count(*) from dba_objects where status = 'INVALID';

The critical point here is the name of the created table. As soon as you are creating a table named SYSTEM under the SYS schema, you will get immediately a huge number of invalid objects under SYS, most of them are DBMS-Packages, ALL-Views and DBA-Views. The number of invalid objects you will get is depending on your Oracle Release, even a recompile with utlrp.sql will not validate all objects, there will still be invalid objects.

To get ride of this problem, just drop the table SYS.SYSTEM and recompile all with the utlrp.sql script.

This shows clearly why you should not allow the creation of application related objects under the SYS schema.
