Oracle users make use of Oracle Heterogeneous Services to integrate non-Oracle data into their primary database. Using the Generic Connectivity agent, Oracle users can communicate to another database or data store, such as XML, via ODBC. DataDirect Connect for ODBC provides the most reliable and highest performing data access for users of Oracle Heterogeneous Services. Connect for ODBC does not require the installation and configuration of database client libraries. This dramatically improves performance and scalability and simplifies configuration of Oracle Generic Connectivity, while providing access to a larger number of various data sources. This paper explains how to use DataDirect Connect for ODBC with Oracle Heterogeneous Services. DataDirect Connect for ODBC in an Oracle Heterogeneous Services Environment Generic Connectivity Architecture Generic Connectivity is implemented by using a Heterogeneous Services ODBC agent. An ODBC agent is included as part of your Oracle system. Be sure to use the agent shipped with your particular Oracle system and installed in the same $ORACLE_HOME. To access the non-Oracle data store using Generic Connectivity, the agent works with an ODBC driver. The ODBC driver that you use must be on the same platform as the ODBC agent. The non-Oracle data stores can reside on the same machine as the Oracle database or a different machine. Installation Steps This example shows the configuration of Generic Connectivity on a SUN Solaris system using DataDirect's ODBC driver to connect to Microsoft SQL Server. Please check your Oracle documentation for specific version and platform support. 1) Install the data dictionary tables and views for Heterogeneous Services. Using the server manager or sqlplus logged on as sys, run caths.sql. For example using the server manager you can use the following example: SQL> connect internal SQL> @<ORACLE_HOME>/rdbms/admin/caths.sql;This script is located in $ORACLE_HOME/rdbms/admin 2) Install the DataDirect Connect for ODBC Driver. Some non-Oracle data stores will require that particular database's client library components to be installed. If the database is DB2, Sybase, SQL Server or Informix, you should use the Connect for ODBC Wire Protocol driver for the particular database you are trying to access. These drivers do not require any additional components to be installed to connect to the database. 3) Configure your odbc data source in the .odbc.ini file. The example below is a data source to connect to Microsoft SQL Server 2000 Note: Annotations to following examples file begin with the symbol and should not be included in the actual file. [MS_SQLServer2000] Configured during ODBC driver installation Driver=/opt/odbc/lib/ivmsssXX.so Description=SQL Server Database=dbname Name of target database. Address=120.2.200.176,1433 IP address and port of target database. Quoteld=No AnsiNPW=No4) Make sure the following entries are in the tnsnames.ora and listener.ora files. TNSNAMES.ORAhsalias= (description= (address=(protocol=tcp)(host=hostname)(port=1521)) (connect_data=(sid=hsmsql)) Needs to match the sid in listener.ora. (hs=ok) hs clause goes in the description. )LISTENER.ORAlistener = (description_list = (description = (address_list = (address = (protocol = tcp)(host = unixhost)(port = 1521)) ) ) sid_list_listener= (sid_list= (sid_desc= (sid_name=hsmsql) Match the sid in tnsnames.ora. (oracle_home=/db/oracle/product/ora92_64) Appropriate $ORACLE_HOME (program= hsodbc) Agent Executable ) )5) Your environment might not need to set LD_LIBRARY_PATH, but you might need to add (ENVS=LD_LIBRARY_PATH=/opt/odbc/lib) to the listener.ora file. For example: LD_LIBRARY_PATH=/db/oracle/product/8.1.6/bin:/opt/odbc/lib/ odbc lib pathAfter the LD_LIBRARY_PATH has been modified, start the listener. (SID_DESC = (ORACLE_HOME = /db/oracle/product/ora92_64) (SID_NAME = hsmsql) (PROGRAM = hsodbc) (ENVS=LD_LIBRARY_PATH==/opt/odbc/lib) ) 6) Run "lsnrctl services" to verify that you now have a service handler for the hsmsql sid. LSNRCTL> services Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXPPROC))) Services Summary... Service "hsmsql" has 1 instance(s). Instance "hsmsql", status UNKNOWN, has 1 handler(s) for this service Handler(s): "DEDICATED" established:1 refused:0 LOCAL SERVER The command completed successfully 7) Create the Initialization file. You must create and customize an initialization file for your generic connectivity agent. Oracle supplies a sample initialization file named "inithsodbc.ora", which is stored in the $ORACLE_HOME/hs/admin directory. To create an initialization file, copy the appropriate sample file and rename the file to initHS_SID.ora. In this example, the SID noted in the listener and tnsnames files is "hsmsql" so the new initialization file is called inithsmsql.ora. Note that the SID name and the initialization file name are case sensitive. 8) Make sure the following entries are in the inithsmsql.ora now located in $ORACLE_HOME/hs/admin INITHSMSQL.ORA# HS init parameters # HS_FDS_CONNECT_INFO = MS_SQLServer2000 odbc data_source_name HS_FDS_TRACE_LEVEL = 0 trace levels 0 - 4 (4 is verbose) HS_FDS_TRACE_FILE_NAME = hsmsql.trc trace file name HS_FDS_SHAREABLE_NAME = full path to odbc driver manager /opt/odbc/lib/libodbc.so # # # ODBC specific environment variables # set ODBCINI=/opt/odbc/odbc.ini location of odbc.ini # # Environment variables required for the non-Oracle system #9) Create a database link to access target database. Be sure to use the appropriate quotes as shown in the following example: SQL> create database link hsmsql SQL> connect to "user" identified by "password" < = valid user/pwd on target DB SQL> using 'hsalias';10) To test, run a simple query of a known table on the target datastore.
