Metadata: [Relational Database] Multi-Model, Data Store (Physical Data Model)
Component: JdbcImport.IbmInformix version 11.2.0
OVERVIEW
This import bridge uses a JDBC connection to a generic database server to extract all its metadata (e.g. Schemas, Tables, Columns, Data Types.) and parse any SQL (e.g. Views, Stored Procedures) to produce the data flow lineage.
This import bridge imports the database server metadata as multi models with one model per schema. Further imports (incremental harvesting) will detect changes in schema to only import changed schemas (reusing already harvested unchanged schemas).
WARNING
The JDBC driver used by this import bridge have limited implementation to extract advanced metadata such as Synonyms, View dependencies, Candidate keys, Stored Procedures, etc. In such case, more advanced queries have to be made to the proprietary system tables, which are specific to each database. Furthermore, such queries have to be performed using the native drivers provided by each database vendor.
This generic JDBC database bridge has only been tested with Oracle, IBM DB2 (DB/2 UDB databases only), Microsoft SQL Server, Sybase and Teradata, (and again provide less metadata than the specific database bridges), and no claims are made for metadata access when using this import bridge with any other database.
Therefore, we recommend using the dedicated database import bridges to access metadata from Oracle, IBM DB2 (DB/2 UDB databases), Microsoft SQL Server, Sybase and Teradata.
REQUIREMENTS
See the driver Location parameter for any JDBC driver requirements.
See the PERMISSIONS section below.
AUTHENTICATION
n/a
PERMISSIONS
Any import bridge is warranted to be read only and only extracts metadata. Therefore the user of this import bridge requires much less permissions than classic users needing to read/write data.
However, this import bridge needs a user with (read only) access to system tables in order to access advanced metadata such as the SQL of views or stored procedures which are not implemented in the metadata portion of the JDBC driver, therefore the Database Administrator (DBA) needs to be involved in order get the proper user with enough permissions.
Note that there are no specific instructions as to what are the minimal set of permissions required as it varies from different database types and versions. In order to ensure that this import bridge is working properly, one must first import using this import bridge with a FULL Sys Admin type username (all permissions), i.e., the same type of username that is used to create and maintain the DB. Once this import bridge is working properly against a given DB, then the DBA may create a user with lesser privileges that still produce a successful result.

FREQUENTLY ASKED QUESTIONS
Q: How does this import bridge load the JDBC driver I want to use?
A: The directory or JAR file pathname must be set in the 'driver path' bridge parameter or in the system CLASSPATH environment variable before starting this import bridge.
Q: Does my driver require any Java security permissions in order to run?
A: Some drivers do require additional security permissions to be granted at runtime. You can grant additional permissions to the driver by editing the 'java.policy' file as below:
grant codeBase 'file:/C:/oracle/ora9/jdbc/lib/classes12.zip' {
permission java.security.AllPermission;
};
Please read your driver documentation for details.
This 'java.policy' file needs to be created in the same directory as the executable, usually ''${MODEL_BRIDGE_HOME}/java'
LIMITATIONS
Refer to the current general known limitations at https://metaintegration.com/Products/MIMB/Help/#!Documents/mimbknownlimitations.html
SUPPORT
Provide a troubleshooting package with:
- the debug log (can be set in the UI or in conf/conf.properties with MIR_LOG_LEVEL=6)
- the metadata backup if available (can be set in the Miscellaneous parameter with -backup option, although this common option is not implemented on all bridges for technical reasons).

STRING | |||||||
| Miscellaneous | INTRODUCTION Specify miscellaneous options starting with a dash and optionally followed by parameters, e.g. -connection.cast MyDatabase1="MICROSOFT SQL SERVER" Some options can be used multiple times if applicable, e.g. -connection.rename NewConnection1=OldConnection1 -connection.rename NewConnection2=OldConnection2; As the list of options can become a long string, it is possible to load it from a file which must be located in ${MODEL_BRIDGE_HOME}\data\MIMB\parameters and have the extension .txt. In such case, all options must be defined within that file as the only value of this parameter, e.g. ETL/Miscellaneous.txt JAVA ENVIRONMENT OPTIONS -java.memory <Java Memory's maximum size> (previously -m) 1G by default on 64bits JRE or as set in conf/conf.properties, e.g. -java.memory 8G -java.memory 8000M -java.parameters <Java Runtime Environment command line options> (previously -j) This option must be the last one in the Miscellaneous parameter as all the text after -java.parameters is passed "as is" to the JRE, e.g. -java.parameters -Dname=value -Xms1G The following option must be set when a proxy is used to access internet (this is critical to access https://repo.maven.apache.org/maven2/ and exceptionally a few other tool sites) in order to download the necessary third-party software libraries. Note: The majority of proxies are concerned with encrypting (HTTPS) the outside (of the company) traffic and trust the inside traffic that can access proxy over HTTP. In this case, an HTTPS request reaches the proxy over HTTP where the proxy HTTPS-encrypts it. -java.parameters -java.parameters -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128 -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass MODEL IMPORT OPTIONS -model.name <model name> Override the model name, e.g. -model.name "My Model Name" -prescript <script name> This option allows running a script before the bridge execution. The script must be located in the bin directory (or as specified with M_SCRIPT_PATH in conf/conf.properties), and have .bat or .sh extension. The script path must not include any parent directory symbol (..). The script should return exit code 0 to indicate success, or another value to indicate failure. For example: -prescript "script.bat arg1 arg2" -postscript <script name> This option allows running a script after successful execution of the bridge. The script must be located in the bin directory (or as specified with M_SCRIPT_PATH in conf/conf.properties), and have .bat or .sh extension. The script path must not include any parent directory symbol (..). The script should return exit code 0 to indicate success, or another value to indicate failure. For example: -postscript "script.bat arg1 arg2" -cache.clear Clears the cache before the import, and therefore will run a full import without incremental harvesting. If the model was not changed and the -cache.clear parameter is not used (incremental harvesting), then a new version will not be created. If the model was not changed and the -cache.clear parameter is set (full source import instead of incremental), then a new version will be created. -backup <directory> Allows to save the input metadata for further troubleshooting. The provided <directory> must be empty. -restore <directory> Specify the backup <directory> to be restored. DATA CONNECTION OPTIONS Data Connections are produced by the import bridges typically from ETL/DI and BI tools to refer to the source and target data stores they use. These data connections are then used by metadata management tools to connect them (metadata stitching) to their actual data stores (e.g. databases, file system, etc.) in order to produce the full end to end data flow lineage and impact analysis. The name of each data connection is unique by import model. The data connection names used within DI/BI design tools are used when possible, otherwise connection names are generated to be short but meaningful such as the database / schema name, the file system path, or Uniform Resource Identifier (URI). The following option allows to manipulate connections. These options replaces the legacy options -c, -cd, and -cs. -connection.cast ConnectionName=ConnectionType Casts a generic database connection (e.g. ODBC/JDBC) to a precise database type (e.g. ORACLE) for SQL Parsing, e.g. -connection.cast "My Database"="MICROSOFT SQL SERVER". The list of supported data store connection types includes: ACCESS APACHE CASSANDRA DB2/UDB DENODO GOOGLE BIGQUERY HIVE MYSQL NETEZZA ORACLE POSTGRESQL PRESTO REDSHIFT SALESFORCE SAP HANA SNOWFLAKE MICROSOFT SQL AZURE MICROSOFT SQL SERVER SYBASE SQL SERVER SYBASE AS ENTERPRISE TERADATA VECTORWISE HP VERTICA -connection.rename OldConnection=NewConnection Renames an existing connection to a new name, e.g. -connection.rename OldConnectionName=NewConnectionName Multiple existing database connections can be renamed and merged into one new database connection, e.g. -connection.rename MySchema1=MyDatabase -connection.rename MySchema2=MyDatabase -connection.split oldConnection.Schema1=newConnection Splits a database connection into one or multiple database connections. A single database connection can be split into one connection per schema, e.g. -connection.split MyDatabase All database connections can be split into one connection per schema, e.g. -connection.split * A database connection can be explicitly split creating a new database connection by appending a schema name to a database, e.g. -connection.split MyDatabase.schema1=MySchema1 -connection.map SourcePath=DestinationPath Maps a source path to destination path. This is useful for file system connections when different paths points to the same object (directory or file). On Hadoop, a process can write into a CSV file specified with the HDFS full path, but another process reads from a Hive table implemented (external) by the same file specified using a relative path with default file name and extension, e.g. -connection.map /user1/folder=hdfs://host:8020/users/user1/folder/file.csv On Linux, a given directory (or file) like /data can be referred to by multiple symbolic links like /users/john and /users/paul, e.g. -connection.map /data=/users/John -connection.map /data=/users/paul On Windows, a given directory like C:\data can be referred to by multiple network drives like M: and N:, e.g. -connection.map C:\data=M:\ -connection.map C:\data=N:\ -connection.casesensitive ConnectionName... Overrides the default case insensitive matching rules for the object identifiers inside the specified connection, provided the detected type of the data store by itself supports this configuration (e.g. Microsoft SQL Server, MySql etc.), e.g. -connection.casesensitive "My Database" -connection.caseinsensitive ConnectionName... Overrides the default case sensitive matching rules for the object identifiers inside the specified connection, provided the detected type of the data store by itself supports this configuration (e.g. Microsoft SQL Server, MySql etc.), e.g. -connection.caseinsensitive "My Database" -connection.level AggregationLevel Specifies the aggregation level for the external connections, e.g.-connection.level catalog The list of the supported values: server catalog schema (default) JDBC DATABASE OPTIONS -system.objects.import (previously -s) Imports all system objects (that are skipped by default). -synonyms.ignore (previously -synonyms) Ignores the synonyms when importing, therefore reducing the size of the model when a large number synonyms exist. -data.dictionary.server <database identification name> (previously -server.name) Sets a server name for the data dictionary to use for extracting tables and view definitions. In a multitenant Container Database (CDB), the metadata for data dictionary tables and view definitions is stored only at the root level. However, each Pluggable Database (PDB) has its own set of data dictionary tables and views for the database objects contained in the PDB. It is possible that some dba_ views are not available because they are not applicable. -driver.fetch.size <number of rows> (previously -f) The database driver fetch size in number of rows, e.g. -driver.fetch.size 100 -model.split (previously -multiModel) Splits a large database model into multi models (e.g. one schema per model). Warning: this is a system option managed by the application calling this import bridge and should not be set by users. -driver.className The full name (including the package name) of the Java class that implements the JDBC driver interface. -tt <string> Set the JDBC table types to import. It helps when the database driver does not support some tables types like EXTERNAL_TABLE. E.g. -tt TABLE;VIEW |
