Oracle database 11g R2 | Issues with accessing enterprise manager | ssl_error_weak_server_cert_key

Hi guys

There is a problem with accessing the Oracle enterprise manager for 11g R2. After a default installation, the EM console will not even load in Internet explorer, while recent versions of firefox will show an error like following:

An error occurred during a connection to FQDN 1158. The server certificate included a public key that was too weak. (Error code: ssl_error_weak_server_cert_key)

This is due to the SSL certificate that used for securing the enterprise management console, if you are not using the database at a production environment, you can disable the secure mode and get the enterprise manager online with minimum efforts.

Please follow the instructions as given below

From an elevated command prompt

set ORACLE_UNQNAME=DATABASENAME

Issue the following command

emctl unsecure dbconsole

(Check the below image for more clarity)

dbconsole_http_change

The above exercise restarts the dbconsole service and you should able to access the enterprise manager without any issues.

Side note: Should you allow DBConsole (Enterprise Manager) & other Oracle services start automatically?

Allowing dbconsole & Oracle services starting with each restart of your laptop or desktop boxes having standard hardware configurations would be very displeasing experience. Oracle services require resources(true) and they definitely take much more time to start up and be online against most of other Windows services.

If you have a box that has barely 4GB memory and processor from an old generation, I suggest you to change the startup method to “Manual” from automatic immediately after the installation. Well, your call :)

Below find the Oracle services for which you can safely change the startup mode as “Manual”

  1. OracleDBConsole<database name> (Aka Enterprise manager, allows you to change system wide configurations, setup backups etc)
  2. OracleMTSRecoveryService (Microsoft Transaction Server, read more here at http://docs.oracle.com/cd/E11882_01/win.112/e26104/using.htm#NTMTS001)
  3. OracleOraDb11g_home1TNSListener (Oracle listener service, mandatory)
  4. OracleService<database name>(Oracle database service)

Once the database configurations are made, you are hardly going to use enterprise manager regularly. That means you don’t even have to start the DBConsole service every time while you restart the database service.

Oracle default Services

I hope the above guidelines help you to save much of the limited resources and let you use your box more effectively while the Oracle services are running.

Windows 8 | Wan miniport | device disconnected

For unknown reasons, the Wan miniport(s) available with Windows 7/8 could start showing errors & giving the user no apparent solutions to fix them, including uninstalling them.

I had the same situation when all of a sudden one of my PPTP connections started giving errors like “Device disconnected”, properties for the PPTP connection not shown and not allowing me to delete the connection in the corrupt state.

After few attempts, I came across a workable solution, posted with Microsoft support site. Unfortunately, this time I forgot to bookmark the page, however, still remember the entire steps. Please find them listed below

View – > Show hidden devices

1

Right click the Wan Miniport device with yellow exclamation mark

(Enlarge the images for more details)

Now force install the driver. Once the installation is over, you can safely uninstall this device. Follow the same for all the Miniport devices those are showing the exclamation mark. Once you are done with the uninstall processes, don’t do anything else. Just restart the computer and start creating the VPN connections once again.

The above exercises must have fixed the Wan miniport issues for you.

Weblogic Server 10.3.6 64Bit on Windows | Difference between 32Bit Installation(s)

Install & Configure Oracle Weblogic Server 10.3.6 & Forms & Reports 11g on Windows8/Windows 2008 R2

Was one of our maximum sought posts & recently I decided to go for a fresh installation of Weblogic 10.3.6 64Bit installation + Forms & reports 11g R2 64Bit. We repeat one of the best articles explain how to is available here and what we are going to provide you additional is few of the things those are different from a typical 32Bit installation.

JDK 8 is not supported (Or my two attempts didn’t bring any fruits)

Node Manager Windows service installation is not offered during the normal/custom installations. That means you MUST install the node manager service by running the .cmd file provided. Default location for the .cmd file is …\wlserver_10.3\server\bin and the file name is “installNodeMgrSvc.cmd”. You should execute this .cmd file from an elevated command prompt!

If you prefer to install a service for Admin server, we have altered the script a little bit and please find it below.

[code language=”text” gutter=”false”]
echo off

SETLOCAL

set DOMAIN_NAME=ClassicDomain

set USERDOMAIN_HOME=D:\WebLogic\user_projects\domains\ClassicDomain

set SERVER_NAME=AdminServer

set WL_HOME=D:\WebLogic\wlserver_10.3

set WLS_USER=weblogic

set WLS_PW=pass123

set PRODUCTION_MODE=true

set MEM_ARGS=-Xms512m -Xmx512m

call "%USERDOMAIN_HOME%\bin\setDomainEnv.cmd"

call "%WL_HOME%\server\bin\installSvc.cmd"

ENDLOCAL

[/code]

I really hope the above tips will make your Weblogic installation more enjoyable.

Windows |Rotate your display

 

Once in a while, awkwardly you press a combination of keys and all of sudden your display is upside down or either by right or left side and you are baffled without an idea how to bring it back to the normal position? Here is the magic key combination

CTRL+ALT+UP Arrow Key (Normal position)

Try the following ones

  1. CTRL+ALT+Down Arrow key (Inverted/upside down)
  2. CTRL+ALT+Left Arrow Key (Taskbar by your right side vertical)
  3. CTRL+ALT+Right Arrow Key (Taskbar by your left side vertical)

Remote Server Administration Tools for Windows 8.1

 

If you are a windows domain administrator, Microsoft “Remote Server Administration Tools for Windows 8.1” would be a perfect companion which will assist you to carryout a major chunk of domain related activities without leaving the comfort of your chair, from a Windows 8.1 client box!

rat

Please note each version of Windows client (starting from Windows 7) requires platform supported update package from Microsoft for the installation, thus, you cannot download the remote administration package for Windows7 or Windows 8 and expect to get it installed on Windows 8.1

Further, You must have US English language installed (Keyboard language is not enough, less said). You must download and install the language pack before installing the remote administration update package.

You must run the Windows Update and make sure your box is patched with latest updates, to avoid any possible installation failures

Install Oracle Database 11g R2 on Windows 8.x, Windows 10

Update: 9th October 2015

The installation procedure mentioned below are applicable for Windows 10 also. So enjoy! I just finished installing the 11G R2 64Bit database in my computer running Windows 10 64Bit professional.

1

I believe if someone is attempting to install Oracle database in a laptop or desktop machine, it is purely for limited development requirements or learning.

A many who are new to Oracle database may not able to install the software on many versions of Microsoft client OS like Windows 7 or 8 until certain levels of hacks are made.

Ignore what “I know everything” geeks screaming across tech forums, asking you questions like “DID YOU READ THE CERTIFICATION MATRIX”

You don’t have the time, neither do I.

Let us install the Oracle database 11g R2 this time on a Windows 8.1 (Update 1) dell laptop with following configuration 8GB memory, 1TB Hdd, Windows 8.1 update 1 64Bit Other oracle software installed

  1. Developer Suite 6i
  2. Developer Suite 10g

Download the installation files from Oracle repositories

  1. There are two files to download, a total of 2GB
  2. Extract the zip files and move the files inside a single folder

Once extracted, you have something like below

  1. Folder Now Switch to the second folder, which reads as “win64_11gR2_database_2of2”
  2. Open up the “components” folder (D:\Oracle11gR2_64Bit\win64_11gR2_database_2of2\database\stage\Components)
  3. There will be four sub-folders within “Components” folder, copy them to D:\Oracle11gR2_64Bit\win64_11gR2_database_1of2\database\stage\Components folder

That’s all. Just start the installation process. Make sure you have changed the virtual memory settings of your box prior the installation (If you already have developer suite 10g, you already changed it) Start the installation by executing “setup.exe” setup You will get one warning, about not meeting the recommended environment requirements (/me chuckles). We didn’t check the 32Bit version of Oracle Database 11g R2, however the method should be same. Hope you enjoyed another post from us

Linux shell script file for Start/Stop Weblogic Services

 

This time we are sharing a shell script for starting/stopping Weblogic services. This shell script can

  1. Start Weblogic Admin Server (after starting Node Manager)
  2. Once the Admin server started, you can start the forms and reports services using the Admin Console
  3. Unless conflicts, you should able to access the Oracle enterprise manager console as well

Copy the content below in plain text file first, change the extension to .sh and set the execute permissions

echo "Starting WebLogic Domain"

nohup $MW_HOME/user_projects/domains/ClassicDomain/bin/startWebLogic.sh > /dev/null 2>&1 &

# Sleep until exiting
sleep 60
echo "All done, exiting"
exit

echo "Stopping Weblogic Server & Node Manager"

nohup $MW_HOME/user_projects/domains/ClassicDomain/bin/stopWebLogic.sh > /dev/null 2>&1 &

sleep 30

# echo "Killing Nodemanager process now"

output=`ps -ef | grep -i nodemanager.javahome | grep -v grep | awk {‘print $2’} | head -1`
set $output
