SPECIFICATIONS
Tool: IBM / PureData System for Analytics Database version 7.0 to 7.2 via JDBC API
See https://www.ibm.com/ibm/puresystems/ie/en/puredata-system-for-analytics.html
Metadata: [Relational Database] Multi-Model, Data Store (Physical Data Model, Stored Procedure Expression Parsing)
Component: JdbcNetezzaImport.IbmPureDataSystemForAnalytics version 11.2.0
OVERVIEW
This import bridge uses a JDBC connection to a IBM Netezza 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).
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.
In case of the IBM Netezza Database:
GRANT LIST ON [database] TO [user];
GRANT LIST ON [database].[schema].TABLE TO [user];
GRANT LIST ON [database].[schema].VIEW TO [user];
GRANT LIST ON [database].[schema].PROCEDURE TO [user];
GRANT LIST ON [database].[schema].FUNCTION TO [user];
GRANT LIST ON [database].[schema].SYNONYM TO [user];
FREQUENTLY ASKED QUESTIONS
n/a
LIMITATIONS
Refer to the current general known limitations at MIMB Known Limitations or bundled in Documentation/ReadMe/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).
Bridge Parameters
Parameter Name | Description | Type | Values | Default | Scope | |||
Driver location | The JDBC driver folder location where all found JAR files will be added to the CLASSPATH. The IBM Netezza JDBC driver default location is: ${MODEL_BRIDGE_HOME}/java/Jdbc/netezza The 'org.netezza.Driver' JDBC driver with the 'Netezza JDBC Driver' name is required. |
DIRECTORY | ||||||
Host | The host name used by JDBC to connect to the database server (localhost by default) e.g. MyDatabaseServer.com or its IP address, e.g. 192.169.1.2 or its full qualified JDBC connection string, e.g. jdbc:netezza://COMPUTER_NAME_OR_IP:PORT/DBname |
STRING | localhost | Mandatory | ||||
Port | The port used by JDBC to connect to the database server (5480 by default for IBM Netezza). This parameter is ignored if the Host parameter is based on a fully qualified JDBC connection string that includes the port. |
NUMERIC | 5480 | Mandatory | ||||
Databases | The subset of database instances to import expressed as a comma (,) or semicolon (;) separated list of databases' names, e.g. database1; database2 To specify the name of the database you would like to use for authentication, you may define the names under the Databases parameter or to use a database with the same name as the user name used to connect to the server. You can use SQL LIKE patterns to identify names of databases. See the Schema parameter documentation for details. |
REPOSITORY_SUBSET | ||||||
User | The user name used by JDBC to connect to the database server. This parameter is ignored if the Host parameter is based on a fully qualified JDBC connection string that includes the user name. Refer to the PERMISSIONS section of this import bridge's main documentation. |
STRING | ||||||
Password | The user password used by JDBC to connect to the database server. | PASSWORD | ||||||
Tables | The subset of "Tables" to import expressed as a semicolon separated list of objects in schemas, like table, view, function, e.g. table1; table2; view1; function1 This parameter also supports the [database.][schema.]table dot annotation in combination with * wildcards to enable specification of what groups of objects to import, e.g. database1.schema1.table1; database1.*.table2; database1.schema3.*; All user objects that the bridge supports are imported if that list is empty. All system tables (e.g. SysAdmin) and objects are ignored by default. If system tables are needed, use the Miscellaneous parameter option -system.objects.import. Table name patterns using a SQL like expression syntax: - Inclusion syntax: using % or *, e.g. A%; %B; %C%; D - start with A or - end with B or - contain C or - equal D - Exclusion syntax: using NOT, e.g. A%; %B; NOT %SYS; NOT 'SYS%' - WHERE (name like A% or name like %B) - and (name NOT like %SYS) - and (name NOT like 'SYS%') - Special characters: ^ $ * + ? | \ ( ) [ ] { } whitespace enclose this name in square brackets and escape special characters, e.g. OneWord%; [Two\sWords.*]; [Dollar\$] |
STRING | ||||||
Stored procedure details | Controls the amount of details imported from stored procedures: 'Signature' The name and parameters of stored procedures 'Code, signature' The above plus code 'None' stored procedure details are not included. |
ENUMERATED |
|
Signature | ||||
Schemas | The subset of schemas to import expressed as a semicolon separated list of schemas' names, e.g. schema1; schema2 This parameter also supports the dot annotation in combination with * wildcards to enable specification of what groups of objects to import, e.g. database1.schema1; database2.*; All accessible user schemas are imported if that list is empty. All system schemas (e.g. SysAdmin) and objects are ignored by default. If system schemas are needed, use the Miscellaneous parameter option -system.objects.import. Schema name patterns using the syntax rules used by the LIKE operator in SQL: - Inclusion syntax: using % or *, e.g. A%; %B; %C%; D - start with A or - end with B or - contain C or - equal D - Exclusion syntax: using NOT, e.g. A%; %B; NOT %SYS; NOT 'SYS%' - WHERE (name like A% or name like %B) - and (name NOT like %SYS) - and (name NOT like 'SYS%') - Special characters: ^ $ * + ? | \ ( ) [ ] { } whitespace enclose this name in square brackets and escape special characters, e.g. OneWord%; [Two\sWords.*]; [Dollar\$] |
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> This option allows to save the bridge input metadata for further troubleshooting. The provided <directory> must be empty. The primary use of this option is for data store import bridges, in particular JDBC based database import bridges. Note that this option is not operational on some bridges including: - File based import bridges (as such input files can be used instead) - DI/BI repository import bridges (as the tool's repository native backup can be used instead) - Some API based import bridges (e.g. COM based) for technical reasons. 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. |
