I am trying to configure a key store in the Play server.
I was able to do this sucessfuly by define command line paramters Dhttps.keyStore and https.keyStorePassword as shown below.
... -Dhttps.keyStore="C:/tempKS/myserver.jks" -Dhttps.keyStorePassword="xxxxx" ...
My question is how to define these two properties in the application.conf instead of passing as parameters at the command line.
I tried this in the application.conf but server didn't pick those values.
https.keyStore="C:/tempKS/myserver.jks"
https.keyStorePassword="xxxxx"
Take a look at https://github.com/typesafehub/activator-play-tls-example/blob/master/app/https/CustomSSLEngineProvider.scala and set it to read from the application's Configuration object.

I am working on externalizing our IScheduledExecutorService so I can run tasks externally on a external cluster. I am able to write a test and get the Runnable to actually run ONLY if I turn on UserCode deployment. If I want to change this task at all and run the tests again I get the below in my external cluster member's logs..
java.lang.IllegalStateException: Class com.mycompany.task.ScheduledTask is already in local cache and has conflicting byte code representation
I want to be able to change the task if I could and redeploy to Hazelcast to just handle it. I do this kind of thing with our external maps now. It can handle different versions of our objects using compact serialization.
Am I stuck using user code deployment for these functional objects? If I need to make a change to it I need to change the class name and redeploy to production. I'm hoping to get this task right the first time and not have to ever do that but I have a way of handling it if I do.
The cluster is already running in production and I'll have to add the following to each member
HZ_USERCODEDEPLOYMENT_ENABLED=true
and the appropriate client code(listed below) to enable this.
What I've done...
Added the following to my local docker file
HZ_USERCODEDEPLOYMENT_ENABLED=true
and also in the code that creates a hazelcast client connecting to my external cluster with
ClientConfig clientConfig = new ClientConfig(); ClientUserCodeDeploymentConfig clientUserCodeDeploymentConfig = new ClientUserCodeDeploymentConfig(); clientUserCodeDeploymentConfig.addClass("com.mycompany.task.ScheduledTask"); clientUserCodeDeploymentConfig.setEnabled(true); clientConfig.setUserCodeDeploymentConfig(clientUserCodeDeploymentConfig);
However, if I remove those two pieces I get the following Exception with a failing test. It doesn't know about my class at all.
com.hazelcast.nio.serialization.HazelcastSerializationException: java.lang.ClassNotFoundException: com.mycompany.task.ScheduledTask
Side Note:
We are using compact serialization for several maps already and when I try to configure this Runnable task via compact serialization I get the below error. I don't think that's the right approach either.
[Scheduler: myScheduledExecutorService][Partition: 121][Task: 7afe68d5-3185-475f-b375-5a82a7088de3] Exception occurred during run

Im trying to get a definition of our AppSettings and ConnectionStrings.
I would like to be able to "fetch" the following:
Key (Name of setting)
Value (The value of the setting)
Provider/builder (From which provider the setting were "picked from", since we use configuraiton builders, such as the UserSecrets and Environment config builders).
The problem is that the application that "requires" this is using ASP.net 4.8.
If this would have been ASP.net core 3+, I could simply use IConfigurationRoot.GetDebugView, or well.. I could simply have a look at the source code of that method and recreate what I need.
https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.configuration.configurationrootextensions.getdebugview?view=dotnet-plat-ext-6.0
https://andrewlock.net/debugging-configuration-values-in-aspnetcore/
But I cant find anything simulair in .Net Framework.
I have tried to find a way to eaither get all Config Builders and then use the keys from ConfigurationManager.AppSettings.AllKeys and ConfigurationManager.ConnectionStrings.AllKeys
and then for each ConfigBuilder call their GetValue-methods which takes a key.. this could work, but Im still unable to get all my configured Configuration Builders. Any ideas?
I want to make a connection to an Oracle database and I have found the following method in the docs:
https://docs.atoti.io/latest/lib/atoti.store.html?highlight=jdbc#atoti.store.Store.load_sql
I call this method with something like this: my_store.load_sql(url, query, username=my_username, password=my_password)
And I use a URL with this form: 'jdbc:XX.XX.XX.XX:YYYY/ZZZZ', but I get the following error:
ValueError: No driver provided and cannot infer it from URL.
I also created this config with a path to a jdbc jar file in my SQL Developer folder, but the error persists:
my_jdbc = 'ojdbc8.jar'
tt.config.create_config(extra_jars = my_jdbc)
Does anyone know how I can solve it or have any example of loading stores from an Oracle database?
Thanks in advance.
The atoti-sql plugin comes with the Oracle driver so you don't need to add an extra jar to the config. However you do need to pass the driver when calling my_store.load_sql. These can be found in the atoti_sql.drivers module.
In your case since you are using an Oracle database, the correct code should be something like:
my_store.load_sql(
url,
query,
username=username,
password=mypassword,
driver=atoti_sql.drivers.ORACLE
)
Given a configuration named "Data:ConnectionString" in appsettings.json file (ASP.NET Core application), how do I override this in the build? By overriding it can either be that there is a step which changes the value in appsettings.json before compilation during build, or that I override the parameter when using "dotnet test", or something else.
More info:
I have a ASP.NET Core application with standard configuration in appsettings.json. I do not want any connection string or sensitive data checked in the source control.
I am building my application using Visual Studio Team Service (cloud TFS). There is a step where tests are executed, and I want these tests to run against a remote service for which I do not want to check in the credentials.
There are a number of extensions available on http://marketplace.visualstudio.com that will help you without any complicated ness.

I like the Variable Tasks Pack that comes with:
Set Variable Set a variable value and optionally apply a transformation to it.
Set Variables with Credential Sets the username/password from an existing service endpoint
Set Variable from JSON Extracts a value from JSON using JSONPath
Set Variable from XML Extracts a value from XML using XPath
Update Build Number Allows you to change a build number
Increment Version Increments a semver version number
Super easy... You can also just search for "json" or "variable" to find other options...
Most popular ways:
Use app secrets
Use scripts section in your project.json. You have 4 events -
precompile, postcompile, prepublish, postpublish
You can set the an environmental variable ASPNETCORE_ENVIRONMENT in the build to something like "Test". Create an appsettings.json file named appsettings.Test.Json. Then when you are setting up your configuration in Startup.cs do something like...
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);
When the environmental variable is set to TEST, you new appsettings file will be loaded and can set the connection string to whatever you want.
I started up my local MYSQL server with the shared memory protocol turned on.
How can I connect to my server with ZeosLib? Where do I specify that it is using shared-memory?
I am using Lazarus(freepascal), although the directions would be the same for Delphi (probably).
Even if the TZConnection has no connection string property you can set the additional connection parameters in TZConnection.Properties.
I presume you run your MySQL server this way
mysqld --skip-networking --shared_memory=1 --shared-memory-base-name='MyMemoryDB'
To enable your shared memory connection you might try to add the following configuration lines into the property TZConnection.Properties at design time in Object Inspector.
Note that the protocol must be set as it is and shared-memory-base-name to the same value as you used in the command line parameter. The default value is MYSQL so if you omit the parameter in command line then you should change the following MyMemoryDB values to MYSQL.
So in TZConnection.Properties property try to add these two lines
protocol=memory
shared-memory-base-name=MyMemoryDB
or at runtime in the TZConnection.BeforeConnect event handler use
procedure TForm1.ZConnection1BeforeConnect(Sender: TObject);
begin
ZConnection1.Properties.Add('protocol=memory');
ZConnection1.Properties.Add('shared-memory-base-name=MyMemoryDB');
end;
Hope this will help you somehow. I haven't tested it because I don't have the proper environment.
IF ZeOS support it, it is probably a textual property that can be added to the (TZ)connection options. Just like other clientlib properties.
