Using Oracle to read data from SQL Server
Hi everyone, Andy from Easysoft Limited here, what I want to show you today is how to get data from SQL Server into Oracle. Now for this we will be accessing SQL Server 2014 from Oracle 12 and getting data across. This could be quite easily be any SQL Server version from 2008 and any Oracle version from 11.2, the configuration and process is the same. We can obviously get access to data on SQL Server prior to 2008 and Oracle prior to version 11.2 but it will need a different configuration to what I am going to show you today The plan is also to add more data to the SQL Server table and show this new data back in Oracle. To start off you'll need access to ensure that you have access to your SQL Server and Oracle databases. You'll also need the Easysoft SQL Server ODBC Driver available from www.easysoft.com; just download it, install it and request the free 14 day trial licence. Before we start we need to make some changes to the standard Easysoft config files. cat /etc/odbc.ini Here I have changed Mars Connection to Yes. It must be set to "Yes" if you are connecting to SQL Server 2005 or newer. Easysoft supports all SQL data types from the version of SQL Server from version 7. Oracle supports data types that are common to most ODBC Drivers, but not some of the SQL Server ones. If you intend to access VARCHAR(MAX) for example, then there are some additional settings that need to be set up. Now as I would like to show you VARCHAR(MAX) data moving from SQL Server to Oracle, I have made the relevant change. As you can see, VarMaxAsLong says "Yes" We now need to create a link from Oracles Database Gateway (DG4ODBC) to the ODBC datasource that we already have, this is done in an init(sid) oracle file; let's have a look at our file. cat $ORACLE_HOME/hs/admin/initsqlsrv.ora Please note that HS_NLS_NCHAR must be set to UCS2 Oracle assume that most database vendors use UTF-8 for wide characters, however Easysoft, like almost all ODBC Driver vendors (including Oracles own ODBC Driver) uses UCS2 for wide characters. So that's the link between DG4ODBC and the datasource setup correctly. Next we need to set up the Listener entry The Oracle Listener waits for incoming requests from the Oracle database. For the Oracle Listener to listen for requests, information about DG4ODBC must be added to the Oracle Listener configuration file, listener.ora cat $ORACLE_HOME/network/admin/listener.ora The PROGRAM=dg4odbc tells the Listener that we are wanting to use the Oracle database gateway to communicate with ODBC. The ENVS=LD_LIBRARY_PATH tells Oracle what library to load Now that's all set up and OK we need to tell Oracle which server to attach the listener entry to. This is done in tnsnames.ora, and he is the file that we ensured was set up earlier. cat $ORACLE_HOME/network/admin/tnsnames.ora The Oracle Listener now needs to be restarted. lsnrctl stop lsnrctl start OK, that's now started the Listener up again. So we have ensured that all the configuration files are set up correctly. The Listener and tnsnames.ora both set up OK. The final step is to create a link from the Oracle database to the "tnsnames.ora" entry. CREATE PUBLIC DATABASE LINK ODBC CONNECT TO "test" IDENTIFIED BY "test" USING 'sqlsrv_ptr'; Right, that's all done. Let's access the data in SQL Server now. select * from [email protected]; Where 'demo' is the name of the SQL Server table and 'odbc' is the public database link name. OK, there we have the data. So to recap, I'm in Oracle and we have managed to read the data from SQL Server. Let's just add an additional row in that SQL Server table and retrieve the new data in Oracle. quit; /usr/local/easysoft/unixODBC/bin/isql.sh -v sqlsrv insert into demo values (2,'Easysoft') select * from demo select * from [email protected]; And there is the new data. Easysoft Limited can help you with your data access ... for our full range of ODBC and JDBC Drivers, Bridges and Gateways visit easysoft.com Be sure to let us know if you have any comments or questions. Until next time, thanks again and we'll see you again soon.

Writing a foreign data wrapper
Experiences with Informix Writing a foreign data wrapper (FDW) for PostgreSQL seems easy. However, there are many pitfalls. This talk will cover experiences from writing a FDW for Informix and will discuss problems with client libraries, data type mapping, optimizer support and performance related topics. Interested attendees will get a short overview on what they can expect from a FDW and (hopefully) learn something to do it better ;)

SQL SERVER PART-12: Oracle Linked Database Server
HOW TO CREATE LINKED SERVER AND HOW TO QUERY ORACLE DATABASE FROM SQL SERVER MANAGEMENT STUDIO. SQL server 2017 makes it easy to configure linked server. You can use open-query to get or manipulate data of linked server database. CONFIGURATION SUMMARY: PROVIDER : oracle provider for oledb. DATA SOURCE : It is usually a combination of oracle server IP: port number/t.n.s listener name. e.g. OPEN QUERY : select * form openquery(linked_server_name, ' sql query statement ') Configure a linked server to enable the SQL Server Database Engine to execute commands against OLE DB data sources outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel. Linked servers offer the following advantages: • The ability to access data from outside of SQL Server. • The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise. • The ability to address diverse data sources similarly. An oracle linked server require OLE DB provider. An OLE DB provider is a DLL that manages and interacts with a specific data source. If your oracle database is not in same server then you have to install The Oracle Data Access Components (ODAC) for Windows consists of Oracle client side drivers. An OLE DB data source identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches. Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The row set request may be in the form of executing a query against the provider or opening a base table from the provider.

Oracle to PostgreSQL database migration and unification project
One of our customers wanted to add a new PostgreSQL database running at AWS RDS to their original Oracle-based system and upgrade the connected Java application to support both database platforms. We delivered a proof of concept by converting one of the largest customer’s database schemas to PostgreSQL in orded to demonstrate how the upgraded system may work. In addition, we updated the application by adding the unified SQL code and changing its architecture to support 2 database platforms.

Transacting with foreign servers - Two's company, three is ...
by Ashutosh Bapat Managing transactions involving multiple foreign servers. PostgreSQL has Foreign Data Wrappers and they are writable too! Upcoming features like partitioning, foreign table inheritance and join-push down for foreign tables pave the path for sharding. One missing piece in the puzzle is the distributed transaction manager required to maintain the atomicity and consistency of transactions involving foreign servers. The presentation talks about the current status of such transactions and discusses the path forward towards distributed transaction manager. Support for writable foreign tables was added in PostgreSQL 9.3. As of now, atomicity and consistency is guaranteed, when a transaction makes changes to at most a single foreign server. It fails to do so when changes are made to multiple foreign servers. In order to achieve atomicity and consistency of transactions involving multiple foreign servers, PostgreSQL needs to take up the role of a distributed transaction manager. The talk covers the current status of distributed transactions. It further explores protocol to drive distributed transactions and infrastructure necessary to overcome various hardware, software and network failures during a distributed transaction. It also covers the use cases like data federation and sharding.
