Start ignite in persistent store mode and query using sqlline console - ignite

I am starting ignite db in persistent mode with following configuration -
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

This configuration is in config/default-config.xml file
After that I am starting sqlline console using -
sqlline.sh --color=true --verbose=true -u
jdbc:ignite:thin://127.0.0.1/
In the console when I am executing any DDL query it gives following error -
java.sql.SQLException: Can not perform the operation because the cluster is inactive. Note, that the cluster is considered inactive by default if Ignite Persistent Store is used to let all the nodes join the cluster. To activate the cluster call Ignite.active(true).

How am I supposed to activate the cluster? where do I call Ignite.active(true)?
Note: I am using Gridgrain ignite community edition version 8.7.5 in ubuntu 18.0.4

The simplest way is to use the control.sh script, which you’ll find in the bin directory:
control.sh --activate
The other ways are documented.

Ignite cache data is lost when docker container is restarted

I want to enable persistence in ignite so that when ignite docker container is restarted or replaced with new version cache data is not lost.
I am using ignite 2.6.0. Here is the configuration file:

I ran following command to deploy ignite docker container
sudo docker run -d -e "CONFIG_URI=" -e "OPTION_LIBS=ignite-core,ignite-spring,ignite-indexing,ignite-rest-http" -v /var/ignitedata:/opt/ignite/apache-ignite-fabric/data -p 9005:8080 --name=apacheignite apacheignite/ignite:2.6.0
I did not pass any value to CONFIG_URI is because i replace the default-config.xml file in the docker container.
I created a new cache using ignite rest api
http://localhost:9005/ignite?cmd=getorcreate&cacheName=myCache
Added sample values to cache
http://localhost:9005/ignite?cmd=put&key=10&val=2018-01-01&cacheName=myCache&keyType=int&valueType=date
I can retrieve the cache value
http://172.30.5.28:9005/ignite?cmd=get&key=10&cacheName=myCache&keyType=int&valueType=date
Now if i restart the docker container and try retrieving value, it does not return value
http://localhost:9005/ignite?cmd=get&key=10&cacheName=myCache&keyType=int&valueType=date
Has anyone seen this issue?
Thanks,
Rahul
Did you activate the cluster after you started it? When you use persistence, you need to tell Ignite how many nodes it should expect to see (called the "baseline").
You do that by running the control.sh script:
./control.sh --activate
You have to make sure that docker container still has same storage mounted, and also set consistentId to same value in configuration.
If you do that, cluster will auto-activate once all nodes have joined. You only have to activate it manually once.
Thank you Andrei Aleksandrov for pointing me to correct direction. I added working directory path and that helped in resolving the issue.
Posting the updated default-config.xml

Configure Apache Ignite Cluster on multiple nodes

I want to setup Ignite cluster on 3 nodes on different IPs. I am following the official guideand using this configuration. I have listed the node IPs in multicastGroup property - unfortunately this does not work, throwing following exception
[09:08:40,852][SEVERE][main][TcpDiscoverySpi] Failed to register local node address in IP finder on start (retrying every 2000 ms; change 'reconnectDelay' to configure the frequency of retries).

How to setup correctly?
You've configured node IPs in the wrong place. Please configure them as follow:
<bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">

<value>10.10.17.1:47500..47509</value>
<value>10.10.17.2:47500..47509</value>
<value>10.10.17.3:47500..47509</value>
</list>
</property>
</bean>
</property>
</bean>
</property>
</bean>
We are using the above configuration. Unfortunately always the node mentioned on top ( here 10.10.17.1:47500..47509) is getting discovered but the other two nodes remain undiscovered.

Apache Ignite JDBC Thin Client Does not work with Existing Cache

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.

Ignite C++ client mode, Near cache

I have an ignite server running in replicated mode and many clients on same node which has near cache enabled. Now I don't find a significant performance difference when I run client with near cache and without near cache.
My understanding of near cache is that frequently used key and value would be stored on client itself, so there won't be an actual Get() call made to server. please correct me if I am wrong.
Can someone share a working near cache configuration xml.

Yes, near cache improves performance by caching often used entries on node locally, but it doesn't make sense if you run all tests on single machine or JVM. Near cache allows not to go on remote node for data, but in your test everything already works locally.
Also Near cache have no sense for server nodes on REPLICATED or PARTITIONED cache, where number of backups equals or bigger than number of data nodes, because all data set already available for each node locally.
So to get performance boost you need to configure client node to use Near cache, when server nodes work on remote machines. Do not forget to warm up near cache before measuring.
Here is XML snippet for setting Near cache:
...
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<!-- Your other cache config -->
<property name="nearConfiguration">
<bean class="org.apache.ignite.configuration.NearCacheConfiguration"/>
</property>

Apache Ignite connection between two nodes

Big Endian architecture was supported pretty decent time ago. Presently, Ignite automatically detects an underlying platform endianness and switches to specific modes of operation. As far as I remember, Apache Ignite community members confirmed that Ignite works on Solaris and Power PC.
