SPECIFICATIONS
Tool: SAP / Data Services (BODI/BODS) version 4.x via JDBC API
See http://www.sap.com/products/data-services.html
Metadata: [Data Integration] Multi-Model, ETL (Source and Target Data Stores)
Component: SapBoDataServices version 11.2.0

OVERVIEW
This import bridge connects to an SAP Data Services (previously BusinessObjects Data Integration) repository to extract the data models of their source and target data stores (e.g. database schema, tables, columns) as well as the data integration ETL/ELT models for the data flow lineage between these data stores.

This import bridge tries to resolve table owner name into physical schema name, based on aliasses of datastore configuration. E.g.
If we have table T_1 with owner name t_1_owner, and configuration contains alias t_1_owner -> my_schema.
Then the table T_1 would be placed in schema: my_schema.

REQUIREMENTS
Ensure that the user has permissions to perform SELECT from SAP tables: AL_COLMAP_TEXT,AL_COLMAP,AL_LANGTEXT,AL_LANG

LIMITATIONS
Refer to the current general known limitations at http://metaintegration.com/Products/MIMB/MIMBKnownLimitations.html or bundled in Documentation/ReadMe/MIMBKnownLimitations.html

This import bridge only extracts the data flow summary lineage (not all the original design details).

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 location of JDBC jar files for the underlying database type, e.g. for SQL Server you may use sqljdbc42.jar.
You may specify any directory you have permissions to read from.
FILE *.*   Mandatory
JDBC URL The JDBC URL where SAP Repository Data Base is running, e.g.

jdbc:sqlserver://SAPHOST:1433;database=SAP_01
OR
jdbc:oracle:thin:@SAPHOST:1521:orcl
STRING   jdbc:sqlserver://localhost:1433 Mandatory
User The user name on whose behalf the connection is being made. This username should have permissions to execute SELECT statements on the AL_COLMAP_TEXT and AL_COLMAP tables. It should NOT be a SAP DataServices native user. It must be a database user. STRING     Mandatory
Password The user's password on whose behalf the connection is being made PASSWORD     Mandatory
Data Flows Description: you can specify a list of data flows to import.
When the list is empty all available data flows are imported.
The list can have one or more data flow names separated by semicolons (e.g. dataflow1; dataflow2).
Patterns support inclusions and exclusions.

An example of inclusion syntax, "A%; %B; %C%; D" that tries to get data flow names that:
- start with A or
- end with B or
- contain C or
- equal D

To exclude a pattern prefix it with 'NOT'. Here is an example of exclusion syntax, "A%; %B; NOT %SYS; NOT 'SYS%'"
that contributes to the following SQL filter: "WHERE (name like A% or name like %B) and (name not like %SYS) and (name not like 'SYS%')"
REPOSITORY_SUBSET      
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.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)

ETL OPTIONS
These options are available on all ETL/DI tools and scripting import bridges in order to:
- Process all SQL parsing
- Build runtime models from design models and runtime variables
- Calculate runtime summary lineage

-etl.summary.add.ultimate (previously -ppus)

Adds the ultimate runtime lineage summary (may generate a very large model).

-etl.summary.only.ultimate (previously -ppsp)

Only produces the ultimate runtime lineage summary (may generate a very large model).

-etl.connections.add.internal.design (previously -pppd)

Adds the internal ETL design data connectors (needed for ETL conversion).

-etl.connections.remove.input (previously -ri)

Removes all input (source) data connections (to reduce the size of the generated model).

-etl.transformations.enable.xml

This option enables the parsing and support of XML transformations in DI/ETL import bridges such as Informatica PowerCenter, Informatica Developer, Microsoft SSIS, IBM DataStage, and Talend Data Integration.
In case of Informatica, such XML transformations corresponds to the following PowerCenter features
https://docs.informatica.com/data-integration/powercenter/10-5/xml-guide/midstream-xml-transformations.html
https://docs.informatica.com/data-integration/powercenter/10-5/xml-guide/xml-source-qualifier-transformation.html
Note that this option may significantly slow down the import.

SAP DATA SERVICES OPTIONS
-statistics=<Statistics_file_path>

Produce ETL import statistics, e.g.
Statistics=C:\Temp\Stats.csv
STRING
