Does anyone know how to construct the database connection string with multisubnet failover as true? We are trying to connect to a SQL Server which is on AOAG (Always on availability group).
We are trying to connect via application where we are using org.springframework.jdbc.datasource.DriverManagerDataSource to create a data source bean and then using it in application.
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${DRIVER_CLASS}"/>
<property name="url" value="${JDBC_URL}"/>
<property name="username" value="{userName}"/>
<property name="password" value="{******}"/>
</bean>
Are you looking for
MultiSubnetFailover=True
From https://learn.microsoft.com/en-us/sql/database-engine/availability-groups/windows/listeners-client-connectivity-application-failover

I have created an Ignite cache "contact" and added "Person" object to it.
When I use Ignite JDBC Client mode I am able to query this cache. But when I implement JDBC Thin Client, it says that the table Person does not exist.
I tried the query this way:
Select * from Person
Select * from contact.Person
Both did not work with Thin Client. I am using Ignite 2.1.
I appreciate your help as how to query an existing cache using Thin Client.
Thank you.

Cache Configuration in the Server Side of the Code
CacheConfiguration<Long, Person> cc = new CacheConfiguration<>(cacheName);
cc.setCacheMode(CacheMode.REPLICATED);
cc.setRebalanceMode(CacheRebalanceMode.ASYNC);
cc.setIndexedTypes(Long.class, Person.class);
cache = ignite.getOrCreateCache(cc);
Thin Client JDBC URL
Class.forName("org.apache.ignite.IgniteJdbcThinDriver");
// Open the JDBC connection.
Connection conn = DriverManager.getConnection("jdbc:ignite:thin://192.168.1.111:10800");
Statement st = conn.createStatement();
If you want to query data from an existing cache using SQL, you should specify an SQL schema in the cache configuration. Add the following code before the cache creation:
cc.setSqlSchema("PUBLIC");
Note that you have persistence configured, so when you do ignite.getOrCreateCache(cc); the new configuration won't be applied, if a cache with this name is already persisted. You should, for example, remove persistence data or use createCache(...) method instead.
I have one use case where I have to support multiple persistence store for my ignite cluster,For example Cache A1 should be primed from Database db1 and Cache B1 should be primed from database db2. can this be done?.In ignite Configuration XML I can only provide one persistence store details,

<property name="username" value="test" />

</bean>
In my CacheStore implementation I can only access this Database right?.
I've not tried this, but if its similar to other bean-configured systems. You should be able to create another bean with a different name and configuration. Then in your cache configuration for A1 and B1 specify the different data sources. That being said, I'm guessing that theoretically.
It may be that you are already doing so, but I can't tell from your question. If you instead choose to implement your caches in this manner https://apacheignite.readme.io/docs/persistent-store you can definitely configure two caches to have different data sources. This is how I'm currently implementing multiple caches. In the cache store I use I specifically call out which database to go to.
Here is a cache configuration I use for mine.
<property name="cacheConfiguration">
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<!-- Set a cache name. -->
<property name="name" value="recordData"/>
<property name="rebalanceMode" value="ASYNC"/>
<property name="cacheMode" value="PARTITIONED"/>

Cache store is configured per cache, so you just need to inject different data sources to different stores. What you showed is just a standalone data source bean, it's not even a part of IgniteConfiguration. You can have multiple data source beans with different IDs.
I have a wso2 is 5.1.0 server runign on Debian. I have a simple servlet that is authenticating using Oauth2 and works perfectly with the users in the primary store.
I have created a secondary store pointing to an openldap server. I have some users and groups and are seen correctly from the IS. I see that when I try to see the User Profile i get the following error:
Error while loading user profile metadata
But when I try to authenticate using the users in the ldap server i get a Login Failed error. I have tried to use both username, DOMAIN/username and username#DOMAIN but none of the worked.
I am starting to think that it could be related to the Calim configuration as the users in the different stores have different values but I don't know how to solve it.
Any ideas on what I am doing wrong?
UPDATED:
This is how I have defined the secondary store.

I can see the users in the list and even create a new one on the LDAP through WSO2 Is, but i cannot see the parameters.
UPDATED:
THe user structure in the LDAP is quite simple.
For the authentication issue, you need to verify "UserNameSearchFilter" attribute is correctly configured. It must mapped to the user name attribute in your ladp server.
<Property name="UserNameSearchFilter">(&(objectClass=user)(cn=?))</Property>
Also you can map attibutes from different user stores to a same wso2 claim. In the mapped attibute section use something like follows,
PRIMARY/attribute1;FOO/attribute2;BAR/attribute3
Also refer - https://docs.wso2.com/display/IS510/Adding+Claim+Mapping
Currently, I am creating dataSource in spring applicationContext.xml by reading DB credentials from a property file.
<!-- property config -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location"><value>/WEBINF/resources/springConfig.properties</value></property>
</bean>
<!-- Database connection Oracle 10g jdbc -->
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
<property name="URL" value="${url}" />
<property name="user" value="${user}" />
<property name="password" value="${password}" />
<property name="connectionCachingEnabled" value="true" />
</bean>
Then i am referencing it using context.getBean
DataSource dataSource = (DataSource)context.getBean("dataSource");
I need to modify my applicationContext to create dataSource by not reading a property file but by using Weblogic JDBC datasource (I am not sure if its jndiTemplate or jdbcTemplate)
Please provide an example and do i need to change the way i do getBean("dataSource") once i use the jndiTemplate?
You want to do a JNDI datasource lookup. Here's an example:

I want to add SSL security in the Database layer. I am using Struts2.1.6, Spring 2.5, JBOSS 5.0 and Informix 11.5. Any idea how to do this?
I have researched through a lot on the internet but could not find any solution.
Please suggest!
Here is my datasource and entity manager beans which is working perfect without SSL:

<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="database" value="INFORMIX" />
<property name="showSql" value="true" />
</bean>
</property>
</bean>
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.informix.jdbc.IfxDriver" />
<property name="url"

Thankyou very much for your suggestion. So basically I need to set something like this in my applicationContext.xml, Please correct me if I am wrong:
<property name="username" value="username" />
<property name="password" value="password" />
**<property name="sslConnection" value="true" />**
<property name="minIdle" value="2" />
But how do I set the SSL certificate in java runtime. The link which you have provided is good but for some reason I am not able to follow. Please put your suggestion.
Using SSL for the communication between an application and a database is something that has to be supported by the database server (and the JDBC driver).
According to the documentation, this is supported by Informix Dynamic Server (IDS) since version 11.50.
You can use SSL support in your Java applications if you use IBM Data Server Driver for JDBC and SQLJ type 4 connectivity to DB2® for z/OS® Version 9 or later, to DB2 Database for Linux®, UNIX®, and Windows® Version 9.1, Fix Pack 2 or later, or to IBM Informix® Dynamic Server (IDS) Version 11.50 or later.
(...)
To use SSL connections, you need to:
Configure connections to the data source to use SSL. (link)
Configure your Java Runtime Environment to use SSL. (link)
The documentation should help.
If you're using a version of IDS prior to 11.50, then I'm afraid you'll have to use SSH tunneling.
