The import command...
impdp user/password DIRECTORY=desktop_import DUMPFILE=SENIORS4_Feb1.dmp TABLES=(DOCUMENT_PUBLISH, MEDIA_APPLICANT) REMAP_TABLESPACE=SENIORDB:import_user REMAP_SCHEMA=SENIORDB:import_user
...causes these errors:
Connected to: Oracle Database 12c Standard Edition Release 12.2.0.1.0 - 64bit Production
ORA-39002: invalid operation
ORA-39166: Object IMPORT_USER.MEDIA_APPLICANT was not found or could not be exported or imported.
ORA-39166: Object IMPORT_USER.DOCUMENT_PUBLISH was not found or could not be exported or imported.
When I searched the web, most of these errors were associated with problems creating log files.
Try to precede table names with their owner name, i.e.
TABLES=(SENIORDB.DOCUMENT_PUBLISH, SENIORDB.MEDIA_APPLICANT)
or even by enclosing both of them into double quotes, such as
TABLES=("SENIORDB"."DOCUMENT_PUBLISH", "SENIORDB"."MEDIA_APPLICANT")

After much effort getting my MVC5 vb.net app configured with Npgsql and EntityFramework6.Npgsql I can connect to the postgres database fine using the Entity Data Model Wizard in Visual Studio 2017, creating a new connection with Data Provider of PostgreSQL Database, entering my database server details and testing the connection (succeeds). I can also double-click the EDMX file and add tables, etc as expected. This is my first project that talks to a postgreSQL database (normally use MS SQL Server). Everything seems to be happy and fine until I encounter code that is a linq statement that attempts to query the database. My Linq statement is:
Dim l_ListOfPwrCycleCrashEvents As List(Of pwr_cycle_crash_events) = (From item In m_AnalyticsEntities.pwr_cycle_crash_events Where item.serialnumber = "0123445678" Select item).ToList
I have the statement in a try/catch block, but visual studio still reports the following:
Exception thrown:'System.Net.Sockets.SocketException' in System.dll Additional
information: A non-blocking socket operation could not be completed
immediately occurred
I cannot seem to figure out why this statement fails. I am able to use similar statements against a different EntityFramework (MS SQL Server) that is also configured in the application.
The complete method that contains the linq statement:
Public ReadOnly Property iCountOfPwrCycleCrashEvents(
ByVal a_sSerialNumber As String
) As Integer Implements IAnalytics.iCountOfPwrCycleCrashEvents
Get
Try
Dim l_ListOfPwrCycleCrashEvents As List(Of pwr_cycle_crash_events) = (From item In m_AnalyticsEntities.pwr_cycle_crash_events
Where item.serialnumber = a_sSerialNumber
Select item).ToList
If (l_ListOfPwrCycleCrashEvents IsNot Nothing) Then Return l_ListOfPwrCycleCrashEvents.Count
Catch l_Exception2 As System.Net.Sockets.SocketException
Dim askjfhakjh As Integer = 7
Catch l_Exception As Exception
Dim kjhadkjh As Integer = 1
End Try
Return 0
End Get
End Property
I am using Npgsql v4.1.1 and EntityFramework6.Npgsql v6.3.0 in an application that targets .NET Framework 4.5.1.
I can't seem to figure out why the linq statement throws this exception or how to solve the problem. What suggestions do you have?
I figured out the issue. I was using 4.5.1 framework because I thought I had a dependency that would not allow me to move to 4.5.2. I went to Package Manager Console and ran the following command:
Update-Package -ProjectName myProjectName -reinstall
By doing so, I found that I had a package that was needed but could not be loaded because it required the 4.5.2 framework (or higher). I changed the framework of the app to 4.5.2 and issued the above Package Manager command and it executed without errors. I ran the app and the linq statement no longer throws an exception.
I am trying to generate a Liquibase change log by running the command generateChangeLog, but I get the following error:

My environment is:
DB2 UDB for AS/400 version 07.01.0000 V7R1m0
AS/400 Toolbox for Java JDBC Driver 10.2
liquibase 3.6.1
Java 8
Maven 3.3.3
syscat.references is not available on Db2 for i. Actually Db2 for i doesn't have a schema named SYSCAT at all.
qsys2.syscstdep seems to be the closest match...
INFORMATION_SCHEMA is the ANSI & ISO standard name for the DB catalog schema. On Db2 for i, it is an alias for QSYS2.
Edit
From the comment by #jmarkmurphy on the OP, it appears there's an Db2 for i Liquibase extension. I don't know for sure, but I'd suspect that installing that would redirect the query to the correct Db2 for i schema & table.
I am new to Hibernate. Using the 5.2.10 FINAL version connecting to Oracle 11g using the Oracle10gDialect with JPA 2.1 and ojdbc8.jar
I try to access a simple stored procedure taking a String input parameter and output a Oracle SYS_REFCURSOR.
StoredProcedureQuery call = session.createStoredProcedureCall("sp_get_profile");
call.registerStoredProcedureParameter(1, String.class, ParameterMode.IN);
call.registerStoredProcedureParameter(2, Class.class, ParameterMode.REF_CURSOR);
call.execute();
An exception occur when I access the function
ERROR SqlExceptionHelper Invalid column type: 2012
DatabaseException::error=[Error registering REF_CURSOR parameter [2]]
I try to write a simple program connecting to DB with the Oracle Driver only. I will have the same error if I register Types.REF_CUSOR as the output parameter to CallableStatement.
cs.registerOutParameter(2, Types.REF_CURSOR);
And the problem can be solved by changing to OracleTypes
cs.registerOutParameter(2, OracleTypes.CURSOR);
Anyone know what is wrong? I need to fall back to use the traditional SQL programming if I cannot get the stored procedure access success. . . please help.
Finally got it work, I should check the Oracle JDBC document first before implementation.
ojdbc8 should be good for Oracle 12c + JDK8 + JPA2.1 with Oracle12cDialect.
For Oracle 11g, need to use ojdbc6.jar
I solved that issue by debugging OJDBC and Hibernate, the building from sources a patched Hibernate CORE library (5.4.15-Final).
I have patched the method ExtractedDatabaseMetaDataImpl.supportsRefCursors which returns always false.
my input: a collection("demo1") in mongo db (version 3.4.4 )
my output : my data imported in a database in hive("demo2") (version 1.2.1.2.3.4.7-4)
purpose : create a connector between mongo and hive
Error:
Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. com/mongodb/util/JSON
I tried 2 solutions following those steps (but the error remains):
1) I create a local collection in mongo (via robomongo) connected to docker
2) I upload those version of jars and add it in hive
ADD JAR /home/.../mongo-hadoop-hive-2.0.2.jar;
ADD JAR /home/.../mongo-hadoop-core-2.0.2.jar;
ADD JAR /home/.../mongo-java-driver-3.4.2.jar;
Unfortunately the error doesn't change; so I upload those version, I hesitate in choosing right version for my export, so I try this:
ADD JAR /home/.../mongo-hadoop-hive-1.3.0.jar;
ADD JAR /home/.../mongo-hadoop-core-1.3.0.jar;
ADD JAR /home/.../mongo-java-driver-2.13.2.jar;
3) I create an external table
CREATE EXTERNAL TABLE demo2
(
id INT,
name STRING,
password STRING,
email STRING
)
STORED BY 'com.mongodb.hadoop.hive.MongoStorageHandler'
WITH
SERDEPROPERTIES('mongo.columns.mapping'='{"id":"_id","name":"name","password":"password","email":"email"}')
TBLPROPERTIES('mongo.uri'='mongodb://localhost:27017/local.demo1');
Error returned in hive :
Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. com/mongodb/util/JSON
How can I resolve this problem?
Copying the correct jar files (mongo-hadoop-core-2.0.2.jar, mongo-hadoop-hive-2.0.2.jar, mongo-java-driver-3.2.2.jar) on ALL the nodes of the cluster did the trick for me.
Other points to take care about:
Follow all steps mentioned here religiously - https://github.com/mongodb/mongo-hadoop/wiki/Hive-Usage#installation

I keep having the following error in MobileFirst Platform 6.3:
Runtime: org.apache.commons.dbcp.SQLNestedException: Cannot create
PoolableConnectionFactory (DB2 SQL Error: SQLCODE=-142,

This is my adapter code:
var test2 = WL.Server.createSQLStatement("SELECT * FROM WSDIWC.WBPTRR1");
function getCEID(cnum) {
return WL.Server.invokeSQLStatement({
preparedStatement : test2,
parameters : []
});
}
And adapter XML:

I have remove the url, user and password.
Hope you help me out on clarification about the current problem.
I already know that the sql is not accepted since it's just a simple query.
I have also research about z/OS DB2 that it has issue with same error code sqlcode=-142. http://answers.splunk.com/answers/117024/splunk-db-connect-db2.html
While you say that this is a "simple query", the exception error code mentions the following:
-142
THE SQL STATEMENT IS NOT SUPPORTED
Explanation
An SQL statement was detected that is not supported by the database.
The statement might be valid for other IBM® relational database
products or it might be valid in another context. For example,
statements such as VALUES and SIGNAL or RESIGNAL SQLSTATE can be used
only in certain contexts, such as in a trigger body or in an SQL
Procedure.
System action
The statement cannot be processed.
Programmer response
Change the syntax of the SQL statement or remove the statement from
the program.
You should review the DB2 SQL guidelines for how to achieve what you want to achieve, and also explain that in the question if you'd like further assistance. For example, are you sure "WSDIWC.WBPTRR1" is actually available?
I encountered this same problem with JDBC connections to mainframe DB2 in MobileFirst 6.3. Connections to DB2 LUW worked fine. It appears that default pool validationQuery is valid for DB2 LUW but not DB2 z/OS.
You can work around the bug by doing the data source configuration in the Liberty profile server.xml. From the Eclipse Servers view, expand MobileFirst Development Server and edit the Server Configuration. Add the driver and data source there; for example:
<library id="db2jcc">
<fileset dir="whereever" includes="db2jcc4.jar db2jcc_license_cisuz.jar"/>
</library>
<dataSource id="db2" jndiName="jdbc/db2">
<jdbcDriver libraryRef="db2jcc"/>
<properties.db2.jcc databaseName="mydb" portNumber="5021"
serverName="myserver" user="myuser" password="mypw" />
</dataSource>
Then reference it in your adapter XML under connectionPolicy:
<dataSourceJNDIName>jdbc/db2</dataSourceJNDIName>
A benefit of configuring data sources in server.xml (vs the adapter XML) is you have access to all data source, JDBC, and JCC properties. So if the connection pool gives you other problems, you can customize it or switch to another data source type, such as type="javax.sql.DataSource".
