context-property of TABLE_PER_TENANT separate schema? - eclipselink

Eclipselink multi-tenant: TABLE_PER_TENANT separate schema
<entity class="mypackage.Foo" >
<multitenant type="TABLE_PER_TENANT" >
<tenant-table-discriminator type="SCHEMA" context-property="xxx"/>
</multitenant>
</entity>
Got the following error:
[EL Warning]: 2014-10-23 21:55:47.406--UnitOfWork(32326774)--Exception [EclipseLink-6168] (Eclipse Persistence Services
- 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.QueryException
Exception Description: Query failed to prepare, unexpected error occurred: [java.lang.NullPointerException].
Internal Exception: java.lang.NullPointerException
Query: ReadAllQuery(referenceClass=Foo )
What should the context-property be? How is it be used? Thanks.

I can't still comment so I am sending you this advice as answer. Look at my article Multi tenancy with EclipseLink and inherited entities. Maybe you are experiencing same problems as I had.

Unable to connect to Google BigQuery using Mule

I am trying to connect to BigQuery for migrating data and I am currently facing some issues in connection.
2 approaches which I am currently focusing on
Database Connector with passing JDBC connection string

It looks some synonyms configuration not correct. You can try it in debug mode or you can check the code and of there is some logging function you can enable it in hac for getting more detail.

it works fine.

I don't understand why prod profile causes this issue.
If someone knows what's wrong here
Thank you.
Reading all the way to the bottom of the stack trace, I see that the root cause is a liquibase checksum validation failure. I'm not sure how familiar you are with liquibase, but it is a tool that is embedded inside jhipster that is used to manage database schema changes as your objects change. What liquibase does is use an XML format to describe the database schema as a series of 'changesets'. When liquibase deploys a changeset (i.e. a changeset that says 'changeset with id "CreateTableFoo" is "create table foo with columns bar baz etc") is that it actually creates the table, and then it also adds a row to a table called 'databasechangelog' that records that the changeset "CreateTableFoo" was successfully applied at such and such a time, and the checksum of that changeset was some value. Now, if you come along and change the changeset xml file so that the changeset "CreateTableFoo" instead creates a table with a different name or different columns, then the checksum calculated for that changeset also changes, so when you try to update the schema liquibase says "Wait! Something wrong!"
So that is what is happening here.
Error creating bean with name 'liquibase' defined in class path resource [com/myapp/config/DatabaseConfiguration.class]: Invocation of init method failed; nested exception is liquibase.exception.ValidationFailedException: Validation Failed:
1 change sets check sum
classpath:config/liquibase/changelog/00000000000000_initial_schema.xml::00000000000001::jhipster is now: 7:788e6cd59e4764c45e1b83437356e748
What this indicates is that the prod database already has had a liquibase update run on it to populate the schema, but that the changeset has changed since that initial deploy. I am not familiar with how jhipster uses liquibase, so you would need to look at the file classpath:config/liquibase/changelog/00000000000000_initial_schema.xml to see what database schema it is trying to set up, and compare that to the schema that is actually in place in production.
Now that things are out of sync, you'll have to figure out a way to get them back in sync, which is more complicated than can be answered here and depends greatly on what the differences between the changelog and the production schema are.

PriviledgedActionException: Able to populate Hbase via Hive, however, unable to query HBase via Hive

I'm using the current Cloudera Quick Start VM. I've created an Hive table with some data. Then, I've created an external table with the Hive Storage Handler. I was able to populate the HBase table. However, while quering the Hive/HBase table, I got the following error (NullpointerException):

I embedded Guava, zookeeper, hbase and hive-hbase-handler JARs. I followed the instructions made in this tutorial: http://www.n10k.com/blog/hbase-via-hive-pt2/
I am using the current Cloudera-Quick-Start VM. Job and Task-Tracker logs as well as Beeswax logs are telling me nothing.
Do you have any ideas about what I am doing wrong?
I am thankfull for any advise!
Best regards, Lena
This is the solution:
Nullpointer exception in HBase MapReduce
The logs were misleading (for me). HBase or Hive was not able to resolve the NameNode.

Deploying worklight project on WAS 8.5

But I am able to deploy the same on the embedded server of eclipse.
And iam not able to see any internal tables under APPCNTR database.
Iam using worklight 6.0 and i installed using installation manager 1.6.3.
Iam using DB2 10.1,I have manually created APPCNTR,WRKLGHT,WLREPORT databases and set the schemas for WRKLGHT as WRKSCHM and WLREPORT as WLRESCHM.
I followed this http://pic.dhe.ibm.com/infocenter/wrklight/v6r0m0/index.jsp?topic=%2Fcom.ibm.worklight.help.doc%2Fdeploy%2Fc_deploy_custom_war_file_to_app_server.html, for Configuring WebSphere Application Server for DB2 manually.

Please help me if I have missed any configuration.
You have not provided details about your environment (Worklight version, WAS profile, database) so it is difficult to pinpoint exactly what the problem could be; my answer is based on certain assumptions, such as that you are using DB2.
Looking closely to the error:
WRKSCHM is the schema name that Worklight Server is trying to access through JPA
CLUSTER_SYNC is a table in the 'WRKLGHT' database
This error can be caused by either the table not being properly created (DB2 setup process is incomplete), or by a schema name mismatch (WAS datasource setup incorrect).
Please verify the following on your environment:
DB2 Setup
Make sure that your DB2 is properly configured for Worklight; verify that the necessary databases are created ('WRKLGHT' for Worklight Server, 'WLREPORT' for the Worklight Reports feature and 'APPCNTR' for Worklight Application Center). The following documentation might be useful to you:
Creating the DB2 databases
Setting up the 'WRKLGHT' and 'WLREPORT' databases
Setting up the 'APPCNTR' database
DB2 Schema Configuration
Make sure that your WAS configuration is properly defining the appropriate schema name that you used in the steps above; the schema name is passed to the JDBC driver using the currentSchema property. The following documentation might be helpful as well:
Configuring DB2 on WAS Liberty profile
Configuring DB2 on WAS Standard profile
DB2 Cheat Sheet (how to list the current DB2 schema names)
DB2 schema qualifiers
I hope this will help you get past this problem.
