I am trying to generate a Liquibase change log by running the command generateChangeLog, but I get the following error:
Starting Liquibase at Fri, 20 Apr 2018 14:26:14 GMT (version 3.6.1

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 trying to do the differential data load from db2 to PostgreSQL table through InfoSphere Federation Server.
Followed below steps and got the expeption:
SQL1822N Unexpected error code "55000" received from data source "FEDSER".
Associated text and tokens are "This ResultSet is closed.".
Please find the below steps which I followed:
create wrapper jdbc

I am using Postgres version 12, Java version "1.8.0_241"
Please help me to resolve this issue. or once connection get created then I can only create the nickname.
Consider using Db2 11.5 instead of InfoSphere Federation Server which went out of support 2017-09-30 https://www.ibm.com/support/lifecycle/#/search?q=InfoSphere%20Federation%20Server
Db2 11.5 includes inbuilt support for PostgreSQL federation in all Db2 editions including Db2 Community Edition

I set up a connection to a Hive server using the Hortonworks ODBC Driver for Apache Hive. Version info is below:
OS: Windows Server 2012 R2 Standard
Hive: 1.2.1000.2.6.5.4-1
Hadoop: 2.7.3.2.6.5.4-1
Hortonworks ODBC Driver for Apache Hive
ODBC Version: 03.80
Driver Version: 2.1.12.1017
Bitness: 64-bit
Locale: en_US
I can run the queries below using the connector that I configured in Teradata SQL Assistant with no issues. I set up my DSN as a linked server in SSMS. However, when I attempt to run the queries in SSMS using openquery, I have some issues. Info on my SQL Server is below:
Microsoft SQL Server 2016 (SP2-CU3) (KB4458871) - 13.0.5216.0 (X64) Sep 13 2018 22:16:01 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows Server 2012 R2 Standard 6.3 <X64> (Build 9600: ) (Hypervisor)
Here is some info on the table that I am querying:
Table Name: instrumentapps_event
Using OPENQUERY, I am capable of querying the Hive DB through SSMS with the following query:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event')
The above query returns the contents of the desired table. However, the query below produces an error:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event WHERE to_date(from_unixtime(UNIX_TIMESTAMP(load_ts,''yyyy/MM/dd''))) >= to_date(''2019-03-01'')')
The error is as follows:
Msg 7355, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "KMhivehttp" supplied inconsistent metadata for a column. The name was changed at execution time.
How can I fix this?
While I'm unsure how to fix the problem that I previously faced (I suspect it to be a bug with the Hortonworks ODBC driver), I did discover a workaround.
Instead of running:
SELECT * FROM OPENQUERY(KMhivehttp,
'SELECT *
FROM dmfwk_gold.instrumentapps_event
WHERE to_date(from_unixtime(UNIX_TIMESTAMP(load_ts,''yyyy/MM/dd''))) >=
to_date(''2019-03-01'')
')
I now use:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event')
WHERE load_ts >= CAST('2019-03-01' AS DATE);
This allows me to avoid any metadata errors.
I am having trouble to import a sql table to H2O.ai using Postgresql JDBC Driver in Ubuntu. I'm getting the follow error:
ERROR MESSAGE:
SQLException: ERROR: relation "XXX" does not exist
Position: 22
Failed to connect and read from SQL database with connection_url: jdbc:postgresql://localhost:5432/...**
I am executing H2O with the follow command:
java -cp h2o.jar:/usr/share/java/postgresql-9.4.1212.jar water.H2OApp
The JDBC driver is installed and already try to construct the Connection URL in several ways.
I'm using this one right now:
jdbc:postgresql://localhost:5432/XXX?&useSSL=false
When you run a query in db2 commandline tool you get explanations like:
db2 => select * from sysibm.systables where owner = 'SAM' and type = 'T';
SQL0206N "OWNER" is not valid in the context where it is used.
SQLSTATE=42703
However, when ran in SQL tab in SquirrelSQL you get only:
Error: DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=OWNER, DRIVER=4.13.127
SQLState: 42703
ErrorCode: -206
Does anybody know of a way of making SquirrelSQL display explanation for the error code like db2 cmd line?
OS: Win 7 x64, db2 10.1
There's a bug in DB2 plugin, I have managed to fix it and posted solution at http://sourceforge.net/p/squirrel-sql/bugs/1073/
I have followed the instructions from here and installed the updated plugin. The error has become:

I am using Hive 0.8.1 on OS X Lion 10.7.4.
Is your query as simple as select * from panstats? I suspect that the query is not the problem, but you'll want to confirm that first.
You could try querying that table from a tool like SQuirreL SQL. If that tool also cannot get the data, then it's probably a Hive issue. If it can... then it's probably an issue with iReport or the Hive plugin.
It sounds like Hive is not configured to share metadata. It uses the annoying default configuration with Derby, so outside connections don't get access to your panstats table. I came across this article about configuring Hive earlier this year. It documents using MySQL instead of derby. If that's indeed the problem, then it's just a Hive configuration issue. Following that article would solve things both for SQuirreL and for iReport.
