  • requires Internet access to and/or other tool sites to download drivers into <TDC_HOME>/data/download/MIMB/.

  • requires the tool to be installed to access its SDK.

Bridge Specifications

Vendor QlikTech
Tool Name Qlik Sense
Tool Version cloud current
Tool Web Site
Supported Methodology [Business Intelligence] Multi-Model, BI Report (Relational Source, Expression Parsing, Report Structure) via WebSocket, REST API
Data Profiling
Incremental Harvesting
Multi-Model Harvesting
Remote Repository Browsing for Model Selection

Tool: QlikTech / Qlik Sense version cloud current via WebSocket, REST API
Metadata: [Business Intelligence] Multi-Model, BI Report (Relational Source, Expression Parsing, Report Structure)
Component: QlikSenseCloud version 11.2.0

This import bridge requires internet access to download third-party libraries:
- such as to download open source third-party libraries,
- and more sites for other third-party software such as database specific JDBC drivers.

The downloaded third-party libraries are stored into $HOME/data/download/MIMB/
- If HTTPS fails, the import bridge then tries with HTTP.
- If a proxy is used to access internet, you must configure that proxy in the JRE (see the -j option in the Miscellaneous parameter).
- If the import bridge does not have full access to internet, that $HOME/data/download/MIMB/ directory can be copied from another server with internet access where the command $HOME/bin/ (or .bat) -d can be used to download all third-party libraries used by all bridges at once.

By running this import bridge, you hereby acknowledge responsibility for the license terms and any potential security vulnerabilities from these downloaded third-party software libraries.

This import bridge imports Business Intelligence (BI) reporting metadata from multiple Qlik Sense applications (QVF apps) in a Qlik Sense Cloud.

This import bridge requires access the Qlik Engine API (JSON over WebSocket) and REST.

In order to successfully import:
- User account utilized must have read access granted.
- This may be accomplished by creating security rules for a specific application and user.
It is imperative that the user have appropriate permissions:
- Read all application objects (especially script)
- Read all data connections (or at least data connections specified in application).

Q: When do I need to generate execution log files?
A: Reports use data load scripts. The execution log files contain information that help the import bridge understand the scripts' expressions. Whenever the script contains variables, loops, or dynamic script statements, execution log files may be useful.

Q: How do I provide information to help the support team reproduce an issue?
A: Provide an archive of the files involved (QVF, QVD, execution logs, external scripts).

Q: How do I avoid the error: Handshake response not received
A: Make sure the host name used to generate the Certificate is the same as the one used in the URL parameter.

Refer to the current general known limitations at or bundled in Documentation/ReadMe/MIMBKnownLimitations.html

Provide a troubleshooting package with:
- the debug log (can be set in the UI or in conf/ 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
Cloud URL The Qlik Sense cloud URL required for the connection to the Qlik Sense Engine API. STRING     Mandatory
Token The API token. PASSWORD     Mandatory
Items List of items, like Spaces, Applications, and QVDs, separated by semicolon.
You can identify items using their Path or ID.
An Item, like an Application or QVD, belongs to a Space. Its Path consists of Space and Item names separated by a slash, like 'Space1/Item1'.
You can filter items in bulk by Path. It allows you to specify what groups of items to include and exclude.
For example, 'Space0;Space2;Space3/Item3;/^*_Test'
means to include all items in Space1 and Space2, Item3 from Space3, and exclude all items with _Test in the name
Here are more examples:
Space1/Item1 | particular item
Space1/Item1;Space2/Item2 | Multiple items (separated by semicolon)
Space1 | all items in a space (space name without slash separator)
Space1;Space2 | multiple spaces
/*substring | Include all items that contain a substring in any space
/^*substring | Exclude all items that contain a substring in any space
Space1/*substring | Include all items that contain a substring in the name and belong to a space
Space1/^*substring | Exclude all items that contain a substring in the name and belong to a space

Advanced user can specify items using the GET/v1/items query parameters.
The parameter value depicts the tail end of the API URL starting with question mark character.
For example, you can get items in the collection with 12345 identifier using parameter value: ?collectionId=12345

If left empty, all applications and QVDs are imported.
Multiple threads Number of worker threads to harvest metadata asynchronously.

- Leave the parameter blank to have the import bridge compute the value, between 1 and 6, based on JVM architecture and number of available CPU cores.

- Specify a numeric value greater or equal to 1 to provide the actual number of threads.
If the value specified is invalid, a warning will be issued and 1 will be used instead.
If you experience out of memory conditions when harvesting metadata asynchronously, experiment with smaller numbers.
If your machine has a lot of available memory (e.g. 10 GB or more), you can try larger numbers when harvesting many documents at once.
Note that setting the number too high can actually decrease the performance due to resource contention.
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.

-java.memory <Java Memory's maximum size> (previously -m)

1G by default on 64bits JRE or as set in conf/, 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 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= -Dhttp.proxyPort=3128 -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass


Override the model name, e.g. "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/, 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/, 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"


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 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:

-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 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. /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. /data=/users/John /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. C:\data=M:\ 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:
schema (default)

-database.type <connection database type>

If databases are accessed via generic ODBC connections, then it is critical to know the exact database type in order to properly parse that database specific SQL syntax for lineage.
The supported database types for SQL parsing are:

Specify the default database connection without any connection name, e.g.
-database.type ORACLE

If multiple database connections are used, then specify each database type using the associated connection name, e.g.
-database.type MyConnectionName=ORACLE

It is possible to mix the default database type with multiple connection database types, e.g.
-database.type ORACLE -database.type MyConnectionName1=TERADATA -database.type MyConnectionName2=DB2

-directory <statement>

A Qlik document DIRECTORY statement is used to set the directory path for subsequent LOAD statements.

If this directory is inaccessible, then use a DIRECTORY statement to redirect it to another directory. To do so, copy the DIRECTORY statement from a Qlik document execution log, add '=' and specify the path to another directory. In the following case, folder 'c:\folder' is redirected to 'd:\folder2' folder., e.g.
-directory "c:\folder1=d:\folder2"

When the path after the DIRECTORY statement is empty, all DIRECTORY statements are redirected to the specified directory, e.g.
-directory "[]=d:\folder2"

-file.path <file directory>

A Qlik document may have statements such as Include, Store, Load statements which operate with file path. If the original file path is not accessible by this import bridge, then it logs the following errors:
- "Unable to open Include file: '\\inaccessible\scripts\include.txt"
- "Could not process the dependency because the source document '\\inaccessible\QVDs\file.qvd' is not accessible"
You can resolve the errors by copying inaccessible files to accessible paths.

If the necessary files are located in "\\inaccessible\folder", then copy them to C:\accessible\folder and instruct the import bridge to read them from the new location, e.g.
-file.path "\\inaccessible=c:\accessible"

The file.path option allows you to replace a portion of the original file path with a new one by specifying multiple file.path options, e.g.
-file.path "\\inaccessible=c:\accessible" -file.path "\\inaccessible2=c:\accessible2"

The import bridge applies multiple -file.path options in order provided.
-file.path "\\a=c:\a" -file.path "\\aa=c:\aa" - The wrong way
-file.path "\\aa=c:\aa" -file.path "\\a=c:\a" - The right way

Make sure not to specify the file.path to be outside of the directory path where you have the QlikSense documents you would like to import.


The Qlik document execution log is required because some critical metadata (e.g. exact source data store tables for lineage) cannot be directly extracted from the Qlik scripts due to their dynamic aspect (e.g. use of loops, subroutines, variable definitions).
This option allows to import even if the execution log is not available, in such case some critical metadata for lineage may be missing.


If user uses IP address in Server URL and gets error " No subject alternative names matching IP address xx.xx.xx.xx found".
This option allows add this IP address to whitelist.
