Connecting to a database from Linux and UNIX systems by using the IBM Integration ODBC Database Extender

IBM® Integration ODBC Database Extender encapsulates the unixODBC driver manager. You must set up and configure the integration node to use it.

Before you begin

The following information applies to all supported databases.

  • Read the information about the unixODBC Project.
  • Create the database.
  • Ensure that your database is set up so that the integration node is authorized to access the database.
  • Check that you have set up your environment so that the integration node can access the database. You might have to run a database profile that is supplied by the database vendor. For more information, see Running database setup scripts before starting an integration node.

You do not need to install the IBM Integration ODBC Database Extender program to use database nodes in your applications. The program code is installed as part of the IBM App Connect Enterprise installation.

Procedure

  1. Copy the odbc.ini sample file that is supplied in the install_dir/server/ODBC/unixodbc/ directory to a location of your choice.
    Each integration node service user ID on the system can therefore use its own data source name (DSN) definitions.
    Note: To prevent problems with the backup and restore procedures, store the copy of the sample file in the /var/mqsi directory, rather than the home directory for your user ID.
  2. Ensure that your copy of the odbc.ini file is owned by the mqbrkrs group, and has 664 permissions.
  3. Set the ODBCINI environment variable to point to your copy of the odbc.ini file, specifying a full path and file name. Ensure that you point to the copy of the file; do not point to the odbc.ini file in the installation directory.
  4. Copy the odbcinst.ini sample file that is supplied in the install_dir/server/ODBC/unixodbc/ directory to a location of your choice. See the Note in step 1.
  5. Ensure that your copy of the odbcinst.ini file is owned by the mqbrkrs group and has 664 permissions.
  6. Set the ODBCSYSINI environment variable to point to the directory that contains your copy of the odbcinst.ini file, specifying a full path name. Ensure that you point to the directory containing the copy; do not point to the directory containing the odbcinst.ini file in the installation directory.
  7. A Data Server driver for ODBC is supplied as part of App Connect Enterprise on Linux® platforms only. If you are using the Data Server driver for ODBC :
    1. Copy the db2cli.ini sample file that is supplied in the install_dir/server/ODBC/unixodbc/ directory to a location of your choice.
    2. Ensure that your copy of the db2cli.ini file is owned by the mqbrkrs group, and that it has 664 permissions.
    3. Set the DB2CLIINIPATH environment variable to point to the directory that contains your copy of the db2cli.ini file, specifying a full path name. Ensure that you point to the directory containing the copy; do not point to the directory containing the db2cli.ini file in the installation directory.
    4. To establish a connection to a DB2® for z/OS® database or Db2 for iSeries database, you need a valid Db2 license which must be placed in the $ACEINSTALL/server/ODBC/dsdriver/odbc_cli/clidriver/license directory. This license is not supplied by App Connect Enterprise; you must obtain it directly from Db2.

    A DataDirect PostgresSQL driver for ODBC is supplied as part of App Connect Enterprise on Linux x86-64 platforms only; it is not available on AIX®.

  8. If you are connecting directly to Db2 server, solidDB, or Informix® databases, set the library search path environment variable to show the location of the libraries for the database manager that you are using. This step is not required if you are using the Data Server driver for ODBC that is supplied as part of App Connect Enterprise.

    For more information about the library search path, ask your database administrator (DBA), or see the documentation for your database manager.

    The library search path environment variable depends on your platform:
    • Linux platformOn Linux, set LD_LIBRARY_PATH.
    • AIX platformOn AIX, set LIBPATH.

    Updates to the library search path are not required for other supported databases.

  9. If you are using a Db2 database instance that is installed on AIX, a single process can make a maximum of 10 connections that use shared memory to a Db2 database. Use TCP/IP mode to connect to the database instance.
  10. Edit the final stanza in the odbc.ini file (the [ODBC] stanza), to specify the location of the installed DataDirect ODBC drivers.
    To ensure that you edit the correct odbc.ini file, you can open the file in the vi text editor by using the following command:
    vi $ODBCINI
    1. In the InstallDir field, add the IBM App Connect Enterprise installation location to complete the fully qualified path to the ODBC directory.
      Ensure that the path points to the ODBC directory in the IBM App Connect Enterprise installation location. If you do not specify this value correctly, the ODBC definition will not work.
    2. Accept the default values shown in the sample odbc.ini file for all the other entries in the stanza.
      For example, on AIX:
      ;##########################################
      ;###### Mandatory information stanza ######
      ;##########################################
      
      [ODBC]
      InstallDir=/usr/opt/IBM/mqsi/12.0.5.0/server/ODBC/drivers
      UseCursorLib=0
      IANAAppCodePage=4
      UNICODE=UTF-8
  11. Edit the first stanza in the odbc.ini file (the [ODBC Data Sources] stanza) to list the DSN of each database.
    For example, on Linux x86-64:
    
    ;##########################################
    ;###### List of data sources stanza #######
    ;##########################################
    [ODBC Data Sources]
    DB2DB=IBM DB2 ODBC Driver
    DB2DSDB=IBM DB2 using the Data Server driver included in ACE
    ORACLEDB=DataDirect ODBC Oracle Wire Protocol
    ORACLERACDB=DataDirect ODBC Oracle RAC Wire Protocol
    ORACLESSLDB=DataDirect ODBC Oracle SSL Wire Protocol
    SYBASEDB=DataDirect ODBC Sybase Wire Protocol
    SYBASEDBUTF8=DataDirect ODBC Sybase UTF8 Wire Protocol
    SQLSERVERDB=DataDirect ODBC SQL Server Wire Protocol
    INFORMIXDB=IBM Informix ODBC Driver
    SOLIDDB_DB=IBM Solid DB ODBC Driver
    DB2ISERIES=IBM i Access for Linux 64-bit ODBC Driver
    POSTGRESQL=DataDirect ODBC PostgreSQL Wire Protocol

    List all your DSNs in your odbc.ini file, regardless of the database manager. You can define multiple DSNs to resolve to the same database; however, if you are using global coordination of transactions with an Oracle database, do not use this option because it might cause data integrity problems.

  12. For each database that you listed in the [ODBC Data Sources] stanza in the odbc.ini file, create a data source stanza in the odbc.ini file. The entries in the stanza depend on the database manager.
    For a Db2 database instance:
    1. In the Driver field:
      • If you are directly connecting to a DB2 server, add the full path of your DB2 installation.
      • If you are using the Data Server driver for ODBC supplied with App Connect Enterprise, ensure that the path points to the driver file in the App Connect Enterprise installation location. The Data Server driver for ODBC is available on Linux platforms only; it is not available on AIX.
    2. In the Description field, type a meaningful description of the database. This field is for information only and does not affect the connection.
    3. In the Database field, type the Db2 alias. The data source name must be the same as the database alias name. If you are using a remote Db2 database, you must set up your client/server connection to resolve this alias to the correct database. For more information, see the Db2 documentation.

      If the requirement is to have multiple stanzas that refer to the same Db2 database, aliases must be created in Db2 by using the Db2 CATALOG command. These aliases can then have their own stanza in the odbc.ini file.

      The odbc.ini file cannot be used to set up aliases for Db2.

      For example, connecting directly to a DB2 server on AIX:

      ;# DB2 stanza
      [MYDB2DB]
      DRIVER=/opt/IBM/db2/V11.1/lib64/db2o.o
      Description=IBM DB2 ODBC Database
      Database=MYDB2DB

      Connecting directly to a DB2 server on Linux systems:

      ;# DB2 stanza
      [MYDB2DB]
      DRIVER=/opt/IBM/db2/V11.1/lib64/libdb2o.so
      Description=IBM DB2 ODBC Database
      Database=MYDB2DB

      Connecting to DB2 using the Data Server Driver on Linux Systems:

      ;# DB2 using DataServer driver included in ACE
      [MYDB2DB]
      DRIVER=/usr/opt/IBM/mqsi/12.0.5.0/server/ODBC/dsdriver/odbc_cli/clidriver/lib/libdb2o.so
      Description=IBM DB2 ODBC Database
      Database=MYDB2DB
      
    For a Db2 database instance on an iSeries system accessed from Linux x64:
    ;# DB2 on iSeries
    [DB2ISERIES]
    Driver=<Your i access client install directory>/lib64/libcwbodbc.so

    DefaultPkgLibrary=QGPL
    DefaultPackage=A/DEFAULT(IBM),2,0,1,0,512
    AllowDataCompression=1
    LibraryView=0
    AllowUnsupportedChar=0
    ForceTranslation=0
    Trace=0
    
    For an Oracle database:
    For all platforms:
    1. In the Driver field, ensure that the path points to the driver file in the IBM App Connect Enterprise installation location, as shown in the following example.
    2. In the Description field, type a meaningful description of the database. This field is for information only and does not affect the connection.
    3. In the HostName field, type the name or IP address of the machine that is hosting your Oracle system.
    4. In the PortNumber field, type the number of the port on which your Oracle server is listening on the machine that you specified in the HostName field.
    5. In the ServiceNamefield, type the Oracle service name that you want to connect to on the system you specified in the HostName field.
    6. If you are using TIMESTAMP WITH TIMEZONE columns, uncomment the EnableTimestampwithTimezone setting.
    7. Accept the default values shown in the sample odbc.ini file for all the other entries in the stanza.
      For example, on AIX:
      ;# Oracle stanza
      [MYORACLEDB]
      Driver=/usr/opt/IBM/mqsi/12.0.5.0/server/ODBC/drivers/lib/UKora95.so
      Description=DataDirect ODBC Oracle Wire Protocol
      HostName=my-machine.hursley.ibm.com
      PortNumber=1521
      ServiceName=my-oracle-service
      CatalogOptions=0
      EnableStaticCursorsForLongData=0
      ApplicationUsingThreads=1
      EnableDescribeParam=1
      OptimizePrepare=1
      WorkArounds=536870912
      ProcedureRetResults=1
      ColumnSizeAsCharacter=1
      LoginTimeout=0
      EnableNcharSupport=0
      ;# Un-comment the next setting if you wish to use Oracle TIMESTAMP WITH TIMEZONE columns
      ;# EnableTimestampwithTimezone=1
    For an Oracle database that uses Real Application Clusters:
    For all platforms:
    1. In the Driver field, ensure that the path points to the driver file in the IBM App Connect Enterprise installation location, as shown in the following example.

    4. In the PortNumber field, type the number of the port on which your Oracle server is listening on the machine that you specified in the HostName field.
    5. In the ServiceName field, type the Oracle Real Application Cluster service name that you want to connect to on the system that you specified in the HostName field.
    6. If you are using TIMESTAMP WITH TIMEZONE columns, uncomment the EnableTimestampwithTimezone setting.
    7. In the AlternateServers field, provide a list of alternative locations for this service for situations when the primary location, which is defined in HostName, is unavailable. Each location specification consists of three parts, which are separated by colons. Enter these values as one continuous string; the text in this example has been split to improve readability.
      HostName=<Alternative host name>
      :PortNumber=<Oracle listner port on alternative server>
      :ServiceName=<Service name on the alternative server>
      If you want to specify more than one AlternateServer, separate each additional location specification with a comma. Whenever a new database connection is required, for example after an Oracle instance failover, the primary location will be tried first. However, if the primary location is unavailable, the driver will try the list of alternative locations in turn.
    8. Accept the default values shown in the sample odbc.ini file for all the other entries in the stanza.
      For example, on AIX:
      ;# Oracle Real Application Clusters stanza
      [MYORACLERACDB]
      Driver=/usr/opt/IBM/mqsi/12.0.5.0/server/ODBC/drivers/lib/UKora95.so

    11. In the TrustStorePassword field, type your SSL trust store password.
    12. In the EncryptionMethod field, type the method to use to encrypt data sent between the driver and the database server. Valid values are as follows:
      • 0 No encryption. This value is the default.
      • 1 SSL. If the server supports protocol negotiation, the driver and server negotiate the use of the SSL protocols specified in the CryptoProtocolVersion connection option.
      • 3 SSL3.
      • 4 SSL2.
      • 5 TLS1.
    13. If the EncryptionMethod has been set to 1, use CryptoProtocolVersion to specify a comma-separated list of the cryptographic protocols to use. Valid protocols are TLSv1.2, TLSv1.1, TLSv1, SSLv3 and SSLv2. When multiple protocols are specified, the driver uses the highest version supported by the server. The default value is TLSv1.2, TLSv1.1, TLSv1.
    14. In the ValidateServerCertificate field, type 1 to enable validation of the certificate that is sent by the database server when SSL encryption is enabled.

    5. In the ServiceName field, type the Oracle service name that you want to connect to on the system that you specified in the HostName field.
    6. If you are using TIMESTAMP WITH TIMEZONE columns, uncomment the EnableTimestampwithTimezone setting.
    7. In the EncryptionLevel field, enter the level of encryption that you are using. Choose one value from the following options:
      • 0 - Rejected. If rejected, or no match is found between the driver and server encryption types, data that is sent between the driver and the database server is not encrypted or decrypted. If the Oracle server has its sqlnet.encryption_server setting set to "REQUIRED" and this option is selected, then the connection to the Oracle database fails.
      • 1 - Accepted. Encryption is used on data that is sent between the driver and the database server if the database server requests or requires it.
      • 2 - Requested. Data that is sent between the driver and the database server is encrypted and decrypted if the database server permits it.
      • 3 - Required. Data that is sent between the driver and the database server must be encrypted and decrypted. If the Oracle server has its sqlnet.encryption_server setting set to "REJECTED" and this option is selected, then the connection to the Oracle database fails.
    8. In the DataIntegrityLevel field, choose one value from the following options:
      • 0 - Rejected. A data integrity check on data that is sent between the driver and the database server is refused. If the Oracle server has its sqlnet.crypto_checksum setting set to "REQUIRED" and this option is selected, then the connection to the Oracle database fails.
      • 1 - Accepted. A data integrity check can be made on data that is sent between the driver and the database server. Data integrity is used if the database server requests or requires it.
      • 2 - Requested. The driver enables a data integrity check on data that is sent between the driver and the database server if the database server permits it.
      • 3 - Required. A data integrity check must be performed on data that is sent between the driver and the database server. If the Oracle server has its sqlnet.crypto_checksum setting set to "REJECTED" and this option is selected, then the connection to the Oracle database fails.
    9. Accept the default values shown in the sample odbc.ini file for all the other entries in the stanza.

      For example, on AIX:

      ;# Oracle using SSL stanza
      [MYORACLEOASDB]
      Driver=/usr/opt/IBM/mqsi/12.0.5.0/server/ODBC/drivers/lib/UKora95.so
      Description=DataDirect ODBC Oracle Wire Protocol
      HostName=my-machine.hursley.ibm.com

      EnableNcharSupport=0
      ;# Un-comment the next setting if you wish to use Oracle TIMESTAMP WITH TIMEZONE columns
      ;# EnableTimestampwithTimezone=1
    Optional Oracle database connection properties:
    KeepAlive
    This property specifies whether the driver enables TCP keepalive. TCP keepalive maintains idle TCP connections by periodically passing packets between the client and server. If either the client or server does not respond to a packet, the connection is considered inactive and is terminated. In addition, TCP keepalive prevents valid idle connections from being disconnected by firewalls and proxies by maintaining network activity. Valid values are 0, which is the default, and means that this function is disabled, or 1, which means that this function is enabled.
    LDAPDistinguishedName
    This property specifies the distinguished name for the LDAP entry that contains your database connection information. Using an LDAP entry simplifies maintenance because it allows you to centrally store and access connection information. LDAP entries specify the hostname, port number, and service name or SID for the target database.
    For example:
    LDAPDistinguishedName=cn=MYORACLEDSN,cn=OracleContext,dc=acme,dc=com

    This property is mutually exclusive with the ServiceName property. If you specify a value for LDAPDistinguishedName, the HostName and PortNumber options are used to specify the hostname and port number for the LDAP directory server.

    QueryTimeout

    This property specifies the number of seconds for the default query timeout for all SQL statements that are created by a connection. The default is 0, meaning that the query does not time out.

    For a PostgreSQL database accessed from Linux x86-64:
    1. In the Driver field, ensure that the path points to the driver file in the IBM App Connect Enterprise installation location.
    2. In the Description field, type a meaningful description of the database. This field is for information only and does not affect the connection.
    3. In the Database field, type the name of the database to which you want to connect.
    4. In the HostName field, type the name or IP address of the server to which you want to connect.

    2. In the Description field, type a meaningful description of the database. This field is for information only and does not affect the connection.
    3. In the Database field, type the name of the database to which you want to connect by default. If you do not specify a value, the default value is the database that is defined by your system administrator for each user.
    4. In the NetworkAddress field, type the network address of your Sybase ASE server (this address is required for local and remote databases). Specify an IP address or server name, in the following format:
      Your Sybase server name or IP address,Your Sybase port number
      For example:
      Sybaseserver,5000
      You can also specify the IP address directly; for example:
      199.226.224.34,5000
      You can find the port number in the Sybase interfaces file, which is named interfaces.
    5. Accept the default values shown in the sample odbc.ini file for all the other entries in the stanza.
      For example, on AIX:
      ;# Sybase Stanza

    For remote access to an SQL Server database
    For all platforms:
    1. In the Driver field, add the IBM App Connect Enterprise installation location to complete the fully qualified path to the driver shown in the sample odbc.ini file.
    2. In the Description field, type a meaningful description of the database. This field is for information only and does not affect the connection.
    3. In the Database field, type the name of the database to which you want to connect by default. If you do not specify a value, the default value is the database that is defined by your system administrator for each user.
    4. In the HostName field, type the name or IP address of the server to which you want to connect.
    5. In the PortNumber field, type the number of the port of the server listener.
    6. To specify a named instance of SQL Server, replace the HostName and PortNumber lines with HostName=Your SQLServer Machine Name\Your SQLServer Instance Name
    7. Accept the default values shown in the sample odbc.ini file for all the other entries in the stanza.
      For example, on AIX:
      ;# UNIX to SQLServer stanza
      [MYSQLSERVERDB]
      Driver=/usr/opt/IBM/mqsi/12.0.5.0/server/ODBC/drivers/lib/UKsqls95.so
      Description=DataDirect ODBC SQL Server Wire Protocol
      Database=SQLSERVERDB
      HostName=my-machine.hursley.ibm.com
      PortNumber=1433
      AnsiNPW=1
      LoginTimeout=0
      QueryTimeout=0
      ;# To specify a named instance of SQL Server replace the HostName and PortNumber lines with
      ;# HostName=<Your SQLServer Machine Name>\<Your SQLServer Instance Name>
      ;# To use Integrated Windows Authentication, reinstate the following line:
      ;# AuthenticationMethod=9
      ;# Domain=<Your Windows Domain Name>
      
    8. If you want to use Integrated Windows Authentication (IWA) for access to the remote SQL Server database, reinstate and complete the lines at the end of the stanza.
    For an Informix database:
    1. In the Driver field, add the full path of your Informix Client library.
    2. In the Description field, type a meaningful description of the database. This field is for information only and does not affect the connection.
    3. In the ServerName field, type the name of the Informix IDS server.
    4. In the Database field, type the name of the database to which you want to connect by default. If you do not specify a value, the default value is the database that is defined by your system administrator for each user.
      For example, on AIX:
      ;# Informix Stanza
      [MYINFORMIXDB]
      Driver=/opt/IBM/informix/lib/cli/iclit09b.so
      Description=IBM Informix ODBC Database
      ServerName=my-machine
      Database=MYDB
    For a solidDB database:
    For all platforms except Linux on POWER® and Linux on Z:

    Client side

    odbc.ini file

    1. In Driver, add the full path of your solidDB Client library.
    2. In Description, type a meaningful description of the database. This field is for information only and does not affect the connection.
    3. In Database, type the name of the database to which you want to connect by default. If you do not specify a value, the default value is the database that is defined by your system administrator for each user.
      For example, on AIX:
      ;# SolidDB Stanza
      [SOLID_DB]
      Driver=/opt/solidDB/bin/soca5x6465.so
      Description=IBM Solid DB ODBC database
      Database=SOLIDDB_DB

      Note: all additional information is ignored.

    solid.ini file

    1. This configuration file is located in the directory that is referenced by the environment variable SOLIDDIR.
    2. The solid.ini mapping is from the data source name (as defined in ODBCINI) to the solidDB connection string.
    3. The connection string takes the form <logical name of the driver> = <physical solidDB connect string>.
    4. The Physical connection string specifies the:
      • Protocol
      • Machine name or IP address
      • Port number to use
      For example, on AIX:
      [Data Sources] 
      SOLIDDB_DB=tcp my_aix_system 1964 

    Server side

    solid.ini file

    1. This configuration file is located in the installation directory for solidDB.
    2. Set the Data Source as for the Client side solid.ini file.
    3. Set Listen to where the listener for the server is located.
    4. Set CharPadding=yes and NumericPadding=yes to turn on padding.
      For example, on AIX:
      [Data Sources] 
      SOLIDDB_DB=tcp my_aix_system 1964
      
      [COM]
      Listen=tcpip 1964
      
      [SQL]
      CharPadding=yes
      NumericPadding=yes
      
  13. Ensure that you have edited all necessary parts of all of the relevant .ini files:
    • The [ODBC Data Source] stanza at the top of the odbc.ini file.
    • A stanza for each data source in the odbc.ini file.
    • The [ODBC] stanza at the end of the odbc.ini file.
    • Additionally, for solidDB, both the client and server-side solid.ini files.
    If you do not configure all parts correctly, the ODBC DSNs do not work and the integration node is unable to connect to the database.
  14. Optional: On AIX, database connect times can sometimes take marginally longer than on Linux platforms due to the IBM Integration ODBC Database Extender searching for unicode conversion libraries that do not typically exist on AIX. To prevent this automatic search, you can set the following property in the [ODBC] stanza of the odbcinst.ini file:
    IconvEncoding=UCS-2

Results

You have now configured database connections on Linux and AIX. You can check that the ODBC environment is configured correctly by running the mqsicvp command. For more information, see mqsicvp command.
