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

https://windows7bugs.wordpress.com/2013/04/06/install-configure-oracle-weblogic-server-10-3-6-forms-reports-11g-on-windows8windows-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.

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

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

VB.Net | Active Directory | Windows Form Application for listing users & details in a grid view

Have you read our previous post about finding last logon date time value for a domain member computer or user yet? If not, please read about it here

Now, we are going to provide you a decent (Warning: Amateurish code blocks possible) Windows forms based application that could list all your domain users and few of their details including last logon date time values.

run

Above image demonstrates the run time interface of the application. Application has a search textbox, that could accept values before and after the user details are populated.

Before the population, the users will be limited to matching string, after population, the list could be refined against the combination of keystrokes

VB.net | Active Directory | Get last logon for computer/user account

Ever wondered how to fetch the last logon details for a domain member computer or user? Using .Net Microsoft has made it pretty easier for the developers to populate the active directory attributes to desired data repositories, however getting the last logon date time value still remains a complex stuff (for beginners like us), especially when your domain consist of multiple domain controllers and they are spread across different geographical areas and subnets :)

After dwelling for long a while, I came across a C# code snippet @ http://www.codeproject.com/Articles/19181/Find-LastLogon-Across-All-Windows-Domain-Controlle that was mostly built against http://www.rlmueller.net/Last%20Logon.htm

I had to copy the codes those were split into multiple blocks for proper explanations, re-arrange and then using the online C# to VB.Net converters, convert to readable VB.Net coding. Again, there were few mismatches and I was able to figure them out through stackoverflow & tech forums posts.

Without going on with what and how I did it, here comes the complete coding. Please note, this is a console application solution, and you should add the references as seen with the below image in order to successfully call the methods and types
