just want to like make with this https://github.com/lettuce-io/lettuce-core/issues/624
but is not a full demo and I don't know how to get StatefulConnection on LettuceConnectionFactory, otherwise I need to manage the connections by myself not by LettuceConnectionFactory . My project is base on SpringBoot

We process and refresh our AAS models in ADFv2 using API calls.
We want to be able vertically scale up (change the tier) just before we refresh the model and then scale back down once it's done.
I can't find an API call to do this or any kind of command to execute within a pipeline in ADF.
It's simple for Azure SQL database
ALTER DATABASE <db_name> MODIFY (SERVICE_OBJECTIVE = 'service-tier')
For reasons out of my control, using runbooks is not an option.
There must be alternatives.
You can leverage the REST API
Set-AzureRmAnalysisServicesServer -ResourceGroupName $ResourceGroupName -Name $AnalysisServerName -Sku "S1"
for altering the tier.
Note: you cannot change between basic to standard via manual or API approach.
You can only alter around within the same scope of tier like S1,S2.S4 etc
You can leverage ADF web activity to do the same
I am new to spring boot and have recently encountered a weird issue. My application which already has a context path runs smoothly on the localhost with a URL like "localhost:port/contextpath/dashboard". But when I try to deploy it on Mesosphere DCOS, it produces an error. Since the mesos server has multiple microservices, each service is separated by a service name,so the service got deployed onto a path like "server.com/servicename/contextpath/dashboard". However, internally the relative mapping is such that any internal reference, be it a navigation like or request mapping of controller ends up something like "server.com/contextpath/dashboard" which misses out on the service name and hence doesn't work.
I would like to know the way for resolving this integration scenario:
Execute different queries to select X elements from a database. I am
looking for an inbound adapter without pooling because it is just
necessary to execute the query once. Although, results of the queries
will be generate only one output.
Work with this data to build a SOAP request (generic web service)
Send this SOAP request to a web service and wait for an asynchronous response.
But also, it is necessary to deploy all this scenario in a WAR file on Tomcat server. I am deploying the application from a spring MVC + spring integration skeleton but I will not have any controller. Is it possible to execute the application when context was loaded on Tomcat?
I am working with the next technologies:
Spring integration
Spring MVC for a WAR deployment
Scheduling (Quartz or #Scheduled)
Spring WS

Since you say that you'd prefer to select on the application start up and only once, you can use:
<int-event:inbound-channel-adapter channel="jdbcChannel"
event-types="org.springframework.context.event.ContextRefreshedEvent"
payload-expression="''"/>
and <int-jdbc:outbound-gateway query="SELECT * FROM ..."/>
And so on to the WebService.
UPDATE
Since you say that you are around Anotation configuration, consider to use Spring Integration Java DSL.
To configure <int-event:inbound-channel-adapter> from #Configuration you should do this:
#Bean
#SuppressWarnings("unchecked")
public MessageProducer ApplicationEventListeningMessageProducer() {
ApplicationEventListeningMessageProducer producer = new ApplicationEventListeningMessageProducer();
producer.setEventTypes(ContextRefreshedEvent.class);
producer.setPayloadExpression("''");
producer.setOutputChannel(jdbcChannel());
return producer;
}
ContextRefreshedEvent info you can get from its JavaDocs or from Spring Framework Manual.
I have a scenario that I want to use the Agent and USM component to implement the customer command to control a computer, but I donot want to install an application or a service,
how can i reach this goal?
thank you very much!
Steve
You can install an empty service, one that does not actually run anything. This is often called a 'recipe about nothing'. It should look something like this:
service {
name "empty"
type "WEB_SERVER"
lifecycle {
locator {
NO_PROCESS_LOCATORS
}
}
}
Add your custom commands here and you can run them from the Cloudify CLI/REST API as usual.
Note the use of the NO_PROCESS_LOCATORS directive - this tells the USM not to perform any process liveness scans.
Hi i am new to oracle coherence,
Question 1 : my scenario is, i have to implement the oracle coherence replicated cache in my webapplication.(with weblogic server).the coherence should be the part of the weblogic server means when i start the weblogic server the coherence should start
(both should run in the single JVM).please help me how to do it ?
Question 2 : whether i need a database to maintain the records or oracle coherence it self maintain in file system ? if yes means how and what will happen for the cached data when i shutdown the server?
Q1:
I would describe it in couple of steps:
Place coherence.jar in the classpath. Depending on specific case it can be WLS classpath or application's classpath. Unless you want to share coherence node between many applications it is often a better idea to put it to application's classpath. It also has other advantages like easier maintenance.
Prepare your own cache configuration for the replicated topology. You can skip this step if you want to use coherence default cache configuration coherence-cache-config.xml which includes replicated topology, but keep in mind that your cache name must start with repl- and this is in general not recommended for production. Otherwise put the following to your custom-cache-config.xml file and add it to your application's classpath.
<?xml version="1.0"?>
<cache-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.oracle.com/coherence/coherence-cache-config"
xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-cache-config
coherence-cache-config.xsd">
<caching-scheme-mapping>
<cache-mapping>
<cache-name>my-repl-cache</cache-name>
<scheme-name>replicated</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<replicated-scheme>
<scheme-name>replicated</scheme-name>
<backing-map-scheme>
<local-scheme/>
</backing-map-scheme>
<autostart>true</autostart>
</replicated-scheme>
</caching-schemes>
</cache-config>
Create a ContextListener for your application and place the following code into contextInitialized method:
// join existing cluster or form a new one
CacheFactory.ensureCluster();
Start your WLS with the following option:
-Dtangosol.coherence.cacheconfig=custom-cache-config.xml
Deploy and start your application (possibly on many servers)
Q2:
In general coherence is in memory solution and doesn't persist data by default. If you need to manage data in persistent store you can look into CacheStore interface. This is described here in the documentation.
Keep in mind that often you have more than one coherence node in the cluster so you will not lose your data when you shutdown one of them because data is always stored also in other JVM(s). When you restart your node it will join the cluster and your data will be there.
Starting with WebLogic 12.1.2, there is excellent Coherence integration via the "Coherence Containers" functionality of WebLogic, in addition to the ActiveCache feature of WebLogic. Here is a URL for the container feature: http://docs.oracle.com/middleware/1212/wls/WLCOH/deploy-wls-coherence.htm
