Getting DB2 .NET Provider to work on Windows 8(64bit)

With every new releases of the Microsoft OS, I’ll have to go through the same pain to get the DB2 providers working. IBM seems not able to release a driver that works out-of-the-box.

So what are the hacks this time to get it working?
  • Start with a normal installation of the DB2 client on your system(don’t forget to run as an administrator).
  • The installation will end successfully but  when you try to connect to a DB2 database, you’ll probably get an error similar to this one:

“sql1159 initialization error with db2 .net data provider reason code 7” 

  • Go to Start -> Programs -> Visual Studio -> Developer Command Prompt.
  • Open the prompt as an administrator
  • Add the following assemblies to the GAC using gacutil:
    • gacutil /if "C:\Program Files\IBM\SQLLIB\BIN\netf40\IBM.Data.DB2.dll"
    • gacutil /if "C:\Program Files\IBM\SQLLIB\BIN\netf40\IBM.Data.DB2.entity.dll"
    • gacutil /if "C:\Program Files\IBM\SQLLIB\BIN\netf40\IBM.Data.Informix.dll"
    • gacutil /if "C:\Program Files\IBM\SQLLIB\BIN\netf20\IBM.Data.DB2.dll"
    • gacutil /if "C:\Program Files\IBM\SQLLIB\BIN\netf20\IBM.Data.Informix.dll"
    • gacutil /if "C:\Program Files\IBM\SQLLIB\BIN\netf20\IBM.Data.DB2.entity.dll"
  • Go to the Windows  8 Start screen and start typing REGEDIT
  • Open the Registry Editor.
  • Go to HKEY_LOCAL_MACHINE -> SOFTWARE -> IBM -> DB2 –> InstalledCopies
  • Click on the folder InstalledCopies
    • Right Click -> New -> String Value
    • Set the value to 10.1.1.DEF.2(the name can be different depending on the DB2 version you tried to install, but you can find the name in the error message when you try to connect)
    • Right Click and Modify. Set the value to DB2COPY1 (your instance name may be different- this is the default)
  • Repeat the task for the registry entry for 10.1.1.DEF.4

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...
