Is there a way to configure snowflakes connection pooling in websphere application serve.
I tried below config inside server.xml file. But not working.
<dataSource id="SnowflakeDataSource" jndiName="jdbc/BM_SF" type="javax.sql.DataSource">
<properties db="abcd" schema="_TARGET" URL="jdbc:snowflake://adpdc_cdl.us-east-1.privatelink.snowflakecomputing.com" user="****" password="****" />
<jdbcDriver libraryRef="DatacloudLibs" javax.sql.DataSource="net.snowflake.client.jdbc.SnowflakeBasicDataSource"/>
</dataSource>
To clarify, the configuration that you have configures WebSphere Application Server Liberty's connection pooling for a Snowflake data source, rather than Snowflake's connection pooling.
The configuration that you have looks mostly pretty good.
When I looked up the SnowflakeBasicDataSource class that you are using, I can see that it has a property called "databaseName", not "db", so you'll need to switch that in your configuration.
You will also need to configure one of the jdbc-4.x features in Liberty if you haven't already, and if you plan to look it up in JNDI (vs inject it), you'll need the jndi-1.0 feature.
Here is an example with some corrections:
<featureManager>
<feature>jdbc-4.2</feature>
<feature>jndi-1.0</feature>
... your other features here
</featureManager>
<dataSource id="SnowflakeDataSource" jndiName="jdbc/BM_SF" type="javax.sql.DataSource">
<properties databaseName="abcd" schema="_TARGET" URL="jdbc:snowflake://adpdc_cdl.us-east-1.privatelink.snowflakecomputing.com" user="****" password="****" />
<jdbcDriver libraryRef="DatacloudLibs" javax.sql.DataSource="net.snowflake.client.jdbc.SnowflakeBasicDataSource"/>
</dataSource>
If this still doesn't work, look into your definition of the DatacloudLibs library to ensure that it is properly pointing at the Snowflake JDBC driver, and if it still doesn't work, post the error message that you see in case it helps to determine the cause.

I am totally new to Jackrabbit and Jackrabbit Oak. I worked a lot with Alfresco though, another JCR compliant open-source content repo.
I want to start a standalone Jackrabbit Oak repo, then connect to it via Java code. Unfortunately the Oak documentation is quite scarce.
I checked out the Oak repo, built it with mvn clean install and then ran the standalone server (memory repository is fine for me at the moment for testing) via:
$ java -jar oak-run-1.6-SNAPSHOT.jar server
Apache Jackrabbit Oak 1.6-SNAPSHOT
Starting Oak-Memory repository -> http://localhost:8080/
13:14:38.317 [main] WARN o.a.j.s.r.d.ProtectedRemoveManager - protectedhandlers-config is missing -> DIFF processing can fail for the Remove operation if the content toremove is protected!
When I open http://localhost:8080/ I see a blank page with code like this but the html / xhtml output as source like this:
I try to connect via Java code:
JcrUtils.getRepository("http://localhost:8080");
// or
JcrUtils.getRepository("http://localhost:8080/rmi");
but getting:

(The Oak documentation is not as complete as the Jackrabbit documentation, but I am also not sure how much of Jackrabbit 2 is still valid for Oak, since it's a complete rewrite.)
I found the same question in the mailing list/Nabble, but the provided answer there does not use a remote, standalone repository but a local one running in the same servlet container and even app (just that eventually the Mongo DB / Node store is configured as remote, but that would mean that the Mongo ports would need to be open). So the app creates the repository itself, which is not my case (I got this case working fine in Oak as well).
In Jackrabbit2 (not Oak), I can simply connect via
Repository repo = new URLRemoteRepository("http://localhost:8080/rmi");
and it's working fine, but this method is not available for Oak, it seems.
Is RMI not enabled by default in Oak? Is there a different URI to use?
However, the documentation of Oak says "Oak comes with a runnable jar" and the runnable jar offers the server method to start the server, so I assume that my scenario above is a valid one.
The blank page is a result of your browser being unable to parse the<title/> tag.
Go into developer mode to see how the browser incorrectly interpreted that tag.

i never saw an example of jackrabbit oak working like this.. are you sure it is possible to start oak outside of your application?
How do you set up the persistent store? (which one are you going to use?).
Here is the link how you normally set up jackrabbit oak: https://jackrabbit.apache.org/oak/docs/construct.html
For example if you use MongoDB as backend (which is the most powerful), you first connect to the db via
Db db = new MongoClient(ip, port).getDB("testDB");
where ip is the ip-address of your MongoDB-server with its port. This server doesn't need to be on the same machine like your Java code is running. You can even use instead of a single MongoDB instance a Replica set.
The same is valid by using a relational db.. only if you choose the tar-file system backend you are limited to your local machine.
Then, in a second step you create a jcr based on the chosen backend (see the link)
I am trying to deploy Virtual Machines from a template into a vApp using the vCloud rest API. I feel that there should be a way to configure a vm as I am spawning it (Since the UI seems to do that) but haven't found a way.
I've been focusing my efforts on recomposing a vApp to add a vm to it. The below example will add a vm but I haven't figured out to configure the vm until after it has been created. Specifically I want to set the VM Name, host name, and IP settings of the vm.
<?xml version="1.0" encoding="UTF-8"?>
<RecomposeVAppParams
xmlns="http://www.vmware.com/vcloud/v1.5"
xmlns:ovf="http://schemas.dmtf.org/ovf/envelope/1">
<SourcedItem sourceDelete="false">
<Source href="templateUri" />
</SourcedItem>
<AllEULAsAccepted>true</AllEULAsAccepted>
</RecomposeVAppParams>
After the vm is created I can reconfigure it but neither the network settings or host name actually change. The vCloud Director UI tells me they have changed but looking on the guest os shows that the settings have not changed.
Change host name example (doesn't work):
<vcloud:GuestCustomizationSection
xmlns:ovf="http://schemas.dmtf.org/ovf/envelope/1"
xmlns:vcloud="http://www.vmware.com/vcloud/v1.5"
href="vmUri/guestCustomizationSection/"
ovf:required="false"
type="application/vnd.vmware.vcloud.guestCustomizationSection+xml">
<ovf:Info>Specifies Guest OS Customization Settings</ovf:Info>
<vcloud:ComputerName>newName</vcloud:ComputerName>
</vcloud:GuestCustomizationSection>
Has anyone been able to configure a VM as you deploy it. Otherwise does anyone know how to effectively configure settings of a VM after it has been deployed. Working XML examples would be amazing but I would still appreciate help in other forms.
The closest I have been able to come to this is to deploy a vApp from a catalog somewhat customizing it in the process. This is not exactly what you asked for, but I hope it helps.

Just use the SDK for this task. Download the example and the library. Add the library to proj and call function from there. The SDK has already and Utility library that handle the http communication with the vcloud creating the requests and serve the answers using serialization.
If you really want to do the request by yourself you just run the example in SDK put Fiddler to spy the communication and get the exact request and reproduce it.
I know because first time I have started making http request using the documentation and get in trouble.
I have configured Quartz endpoint for the scheduling requirement. However currently in my route configuration, trigger information is hard coded in the XML configuration file. As per the requirement, trigger information needs to come from DB.
<camel:route>
<camel:from uri="quartz://commandActions/MSFI?cron=15+17+13+?+*+MON-SUN+*" />
<camel:bean ref="userGateway" method="generateCommand" />
<camel:to uri="wmq:SU.SCHEDULER" />
</camel:route>
Quartz documentation says Jobs and triggers can be stored in database and are accessed using JDBCJobStore. Is it possible to configure Camel Quartz endpoint to use JDBCJobStore? I tried to find out an example but couldn't find. If someone has implemented this before, kindly share an example.
Thanks,
Vaibhav
Yeah see the quartz documentation how to configure it to use a jdbc job store. You can do this using a quartz.properties file, which you can tell Camel to use.
See the Camel side part here: http://camel.apache.org/quartz at the section Configuring quartz.properties file
We are using mybatis 3, I am want to see the SQL logs but couldn't find how to enable it. I am using log4j in my application.
I followed this mybatis documentation - http://mybatis.github.io/mybatis-3/logging.html , but when I run the application I get the below exception. Am I missing something,
Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL
Mapper Configuration. Cause:
org.apache.ibatis.builder.BuilderException: The setting logImpl is not
known. Make sure you spelled it correctly (case sensitive).
Have given this setting in mybatis configuration file under configuration
<settings>
<setting name="logImpl" value="LOG4J"/>
</settings>
My situation was the same: I was using mybatis 3.1, and received same error. Is seems like logImpl property was added in later versions (3.2).
Experimentally I've found out, that mybatis was trying to use slf4j for logging, while I want to use log4j.
For me the fix was to add dependency on slf4j-log4j bridge library( I'm using: log4j 1.2.17, slf4j-log4j12 1.7.5). So, the workaround is not to set logger for mybatis, but to set another implementation for default logging interface (slf4j-api).
I have a feeling this is a stupid question but I can't find the answer anywhere...
I need to deploy 2 Jira instances on asingle Tomcat server, I can't figure out how to pass in the jira.home property
The documentation says I need to:-
Add a web context property called 'jira.home' — this property is set in different files depending on your application server. For example, for Tomcat (and therefore for JIRA Standalone), you will need to configure the server.xml file. For other application servers you may need to configure the web.xml file, or set 'Context parameter' options on the deployment UI of the application server, etc. Note that If you have specified a JIRA home in jira-application.properties (ie. the recommended method), it will override your web context property.
I was hoping something like this would work.
<Context jira.home="d:/jira/data" path="" docBase="D:\Jira\atlassian-jira-enterprise-4.1\dist-tomcat\tomcat-6\atlassian-jira-4.1.war" debug="0">
<Resource name="jdbc/JiraDS" auth="Container" type="javax.sql.DataSource"
username="sa"
password="*****"
driverClassName="net.sourceforge.jtds.jdbc.Driver"
url="jdbc:jtds:sqlserver://*****:1433/jira41_519;user=****;password=****"
/>
<Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction"
factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/>
<Manager pathname=""/>
</Context>
Any ideas??
ah ha!
This is what I was looking for!
<Parameter name="jira.home" value="d:/jira/dataResearch" override="false"/>
