Java has had quite a few security issues recently. Therefore, it definitely makes sense to enable the Java Updater and to install every Java update right after Oracle releases it. However, on my different Windows (64bit) boxes I could not configure the Java Updater. There was simply no “Update” tab…
When I tried to access a network share on a Windows 2008 server locally (!) today using a DNS alias I configured, I got System error 5 has occurred. Access is denied (Systemfehler 5 aufgetreten. Zugriff verweigert in German): As you see in the screenshot, the shares are enumerated correctly…
In one of my recent PowerShell scripts I needed to find out if certain commands (in my case “svn”, “git”, “ant” and “mvn”) were available or not. I wrote this small function that tries to call the given command and returns whether it is callable. function commandAvailable($cmd, $options) { $error.clear();…
Until today, I thought to be able to connect to an Oracle database from your Windows machine, you need to install the complete Oracle client including the Enterprise Manager etc. (>1GB). However, today I finally found a way to use Oracle via ODBC using only the InstantClient (ca. 50MB) on…
Apparently, PowerShell’s get-content cmdlet automatically converts the contents of text files into an array of strings, splitting the contents at the line breaks (see Using the Get-Content Cmdlet). In many cases this is convenient: Contents of file test.txt: 1 2 3 gc text.txt | % { write-host “line: ” $_…
After I installed the latest version of PL/SQL Developer on my Windows 7 64bit machine today, I got the following error message when trying to connect to an Oracle database: Initialization error Could not initialize “D:\oracle\product\11.2.0\client_1\bin\oci.dll” Make sure you have the 32 bits Oracle Client installed. As I’ve found out,…
When installing Microsoft Baseline Security Analyzer (MBSA) the installation on my Windows 7 64bit machine failed with error code 2738. However, I found the solution for this problem in the Chip forum: Remove the registry key HKEY_CURRENT_USER\SOFTWARE\Classes\Wow6432Node\CLSID\. Register vbscript.dll running regsvr32 C:\Windows\SysWOW64\vbscript.dll as Administrator.
GnuPG for Windows 7 stores all its key files in %USERPROFILE%\AppData\Roaming\gnupg, but I wanted to change this path, say to D:\Profile\GPG, so that the files can easily be backed up. It turns out, there are quite a few different methods to change the path: changing the default keyring location in…
I am used to verify downloaded programs with GnuPG simply by entering the following command: gpg2 –verify program.exe.sig Usually, GnuPG finds out which file to hash (in this case program.exe) on its own. But in case of PuTTY, all I got was this: gpg2 –verify .\putty.exe.DSA gpg: keine signierten Daten…
Wenn man verhindern möchte, dass Windows bei der Installation ein lokales Benutzerkonto anlegt (sinnvoll z.B. wenn der PC nur von Domänenbenutzern bedient werden soll), kann man dem obligatorischen Benutzerkonto den Namen “Benutzer” geben. Da Windows (in der deutschen Version) automatisch eine Benutzergruppe mit dem Namen Benutzer anlegt, kann das Benutzerkonto…
