Replicate - MySQL source defect and fix (2022.5 & 2022.11)
The dedicated tFTPxxx components do not support reading files directly from FTP servers. Usually the file is obtained from the FTP server to the local system first and then the file is read. However, this can cause performance issues when many files or large files need to be read.
One solution is to use the JSch library, which allows the creation of an InputStream object from a file via SFTP. Then, use the tFileInputDelimited component to read data from the InputStream object. This avoids downloading the file to the local system.
For example, in the following Job, the Java code iterates over the FTP files one by one, using a JSch library file and a tFileInputDelimited component to read the file directly.
The tLibraryLoad component loads the jsch-0.1.55.jar JSch library file, then the tJava component uses the following code to create the InputStream object for the current FTP file.
JSch jsch = new JSch();
Session session = null;
try {
session = jsch.getSession("username", "localhost", 22);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword("password");
session.connect();
Channel channel = session.openChannel("sftp");
channel.connect();
ChannelSftp sftpChannel = (ChannelSftp) channel;
java.io.InputStream in=sftpChannel.get( ((String)globalMap.get("tFTPFileList_1_CURRENT_FILE")));
globalMap.put("sftp_inputStream",in);
} catch (JSchException e) {
e.printStackTrace();
} catch (SftpException e) {
e.printStackTrace();
}
The tFileInputDelimited component reads the data from the InputStream object:
When using tFileInputRaw to load file contents as a string, the Job fails with an OutOfMemoryError if the file size exceeds 2GB. This happens even if there is enough memory and the JVM parameter "-Xmx" value is increased to a higher value.
A Java String internally uses a char array (example: char[]) and the indices of an array is an integer. The maximum value of an integer is Integer.MAX_VALUE, which is 2^31 – 1 (or approximately 2 billion). So, you can store a file up to 2 GB in size as a String, and for which you need at least 4 GB memory to store as each char is 2 bytes in Java, plus additional ~4 GB memory for creating the String object, so, in total around 8GB of heap space.
Java String & Array limitations and OutOfMemoryError
Reading ~2 GB file into memory is not a good design. Avoid loading ~2GB large files into strings at once, split the file into smaller files, and then use tFileList to iterate over each file.
Sometimes we need to join different tables in the source databases and filter records according to another table records values. In this article we are using Oracle source endpoint, to demonstrate how to build up such a task in Qlik Replicate.
In the below sample task, table testfilter will be replicated from Oracle source database to SQL Server target database. During the replication, the records which value is INACTIVE in table testfiltercondition will be filtered out and are ignored in both Full Load and CDC stages. The two tables are joined by the same primary key column "id".
In the above expression, the 2 tables testfilter and testfiltercondition are joined by the PK column "id" in function source_lookup.

QnA with Qlik: Qlik Replicate Tips
Qlik Replicate SAP Extractor Endpoint can be tuned to improve the performance of data being processed from an SAP environment. This is achieved by adding an internal parameter: sqlConnector. To confirm the performance improvements of the task, first record the task duration before implementing the parameter, then compare it to the subsequent runs.
Before the internal parameter can be added to the Qlik Replicate Extractor Endpoint, the below SAP Transports must be installed:
Once the transports have been installed make sure you follow the below steps to set the added Permissions on the SAP Replicate User:
Add the following authorization objects and settings to the RFC user ID:
Do the following:
For more information on how to import/upgrade the sqlConnector Transport, see Importing the SAP transports.
Configure the SAP Extractor Endpoint by defining the useSqlConnector Internal Parameter.

From RE v2.13 later on versions , you need to have JDK/JRE 17 as a must, but customers still need to keep compatibility with JDK 8 or 11.
Check the following etc folder based configuration and change it to installed jdk/jre path:
{ org.talend.ipaas.rt.dsrunner.cfg --> ms.custom.jre.path org.talend.remote.jobserver.server.cfg --> org.talend.remote.jobserver.commons.config.JobServerConfiguration.JOB_LAUNCHER_PATH }
The tChronometerStart and tChronometerStop components can achieve this goal to calculate the execution time of a subjob for analysis or output to the log file, not the execution time of the entire job:
A sample Job design looks like below.
On the basic settings panel of tChronometerStop_1 component, select 'Since a tChronometerStart' option to stop time measurement launched and calculate execution duration of the subjob.
Note: the execution duration of the subjob is stored in a pre-defined global variable
eg:((Long)globalMap.get("tChronometerStop_1_DURATION")). This is a Flow variable and it returns a long.
This variable can be used directly later on other subjob. To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it.

You will find here how to call QMS API using PowerShell with some examples.
Please note that there are some requirements to use the QlikView Management Service API. For more detail see QlikView Management Service API
First of all the IQMS interface is deprecated in QlikView 12 and IQMS2 should be used instead.
For example, using IQMS in QlikView 11:
http://ws.qliktech.com/QMS/ 11/IQMS/GetTimeLimitedServiceKey
But in QlikView 12, this should be:
http://ws.qliktech.com/QMS/ 12/IQMS/GetTimeLimitedServiceKey
Using IQMS2 in QlikView 12 will look like:
http://ws.qliktech.com/QMS/ 12/2/IQMS2/GetTimeLimitedServiceKey
Differences between IQMS and IQMS2
There are some differences in the intended use of the QMS API between QlikView 11.20 and QlikView 12.10. For these reasons, a new QMS API interface was introduced with QlikView 12.10, IQMS2, while the QMS API interface used for QlikView 11.20 is available as IQMS.
This ensures that customers who have built their clients for QlikView 11.20 can use them with no modifications when upgrading to QlikView 12.10 or later.
IQMS2 have a number of additional methods that are not available in IQMS. If you want to create a new API client on QlikView 12.10 or later, you are recommended to use IQMS2 because of the extra functionality it offers. If you downgrade to QlikView 11.20 while your API client is utilizing the IQMS2 namespace, you must change to the IQMS interface and remove all references to IQMS2 methods that are not available in IQMS.
Reference: QlikView Management Service API
Environment:
First of all before performing a call, you need to get a Service Key. This is used for most of API calls towards the QMS API.
## URL for the QMS API endpoint $url = "http://servername:4799/QMS/Service" $service = New-WebServiceProxy -Uri $url -Namespace QlikViewServer -UseDefaultCredential $serviceKey = $service.GetTimeLimitedServiceKey()
In return you will get a temporary Service Key which will expired 60 seconds after it was generated.
Now that you have the Service Key, you can reuse it perform API calls against the QMS API.
Below is an example of a script to run a task
$TaskID = 'a6fa2db1-3a8c-4ef4-b102-98ed30369f5d' $hdrs = @{} $hdrs.Add("SOAPACTION","http://ws.qliktech.com/QMS/12/2/IQMS2/RunTask") $hdrs.Add("Content-Type", "text/xml;charset=utf-8") $hdrs.Add('X-Service-Key',$serviceKey) $body = @{} $body = '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body> <RunTask xmlns="http://ws.qliktech.com/QMS/12/2/"> <taskID>' + $TaskID + '</taskID> </RunTask> </s:Body> </s:Envelope>' $res = Invoke-WebRequest -Uri $url -Method Post -Body $body -UseDefaultCredential -Headers $hdrs
Run an EDX Task (This accept either the Task ID or the Task Name)
$TaskIdorName = 'test' $EDXPassword = '123' $hdrs = @{} $hdrs.Add("SOAPACTION","http://ws.qliktech.com/QMS/12/2/IQMS2/TriggerEDXTask") $hdrs.Add('X-Service-Key',$serviceKey) $body = @{} $body = '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body> <TriggerEDXTask xmlns="http://ws.qliktech.com/QMS/12/2/"> <taskNameOrID>' + $TaskIdorName + '</taskNameOrID> <password>' + $EDXPassword + '</password> </TriggerEDXTask> </s:Body> </s:Envelope>' $res = Invoke-WebRequest -Uri $url -Method Post -Body $body -UseDefaultCredential -Headers $hdrs -ContentType "text/xml;charset=utf-8"

When using Qlik Sense Mobile to connect to a Qlik Sense Enterprise client-managed server, going through an Apache reverse-proxy, apps can be downloaded and accessed offline.
Online access, on the other hand, results in a blank screen.
The information in this article is provided as-is and to be used at own discretion. Depending on tool(s) used, customization(s), and/or other factors ongoing support on the solution below may not be provided by Qlik Support.
The issue is environmental, and it will need investigating and verifying Apache's rewrite rules, which falls outside the scope of Qlik Support.
In one specific example, one rewrite rule contained a trailing slash ("/") at the end of the server's URL.
<Location /sense>
ProxyPass https://servername/sense/ connectiontimeout=500 timeout=7200 retry=0 keepalive=On
ProxyPassReverse https://servername/sense
</Location>
Removing the / at the end of https://servername/sense in the ProxyPass key resolved the issue.
As this is just an example, feel free to request assistance with investigating the rules from the userbase on Qlik Community or to engage Qlik Professional Services via your account manager.

Q&A:
Q: Can we make App specific Data Job alerts (Success/Failure)?
A: Yes, if you would like to get an alert when a specific app has been reloaded successfully or otherwise has failed, then you can use “System alerts”
Q: From which Qliksense version onwards alerts are available?
A: According to the help page: Minimum recommended version of Qlik Sense Enterprise on Windows is February 2019.
Q: How can I get an alert if a QlikView job fails to load, or if an NPrinting job fails to execute?
A: Not possible, for now Qlik Alerting is only available to set it up with Qlik Sense, starting from QS February 2019 .
Q: Hello, I have a questions regarding the conditions. They seemed to only use operators, but can we apply filters or selections to the alert?
A: Yes, you can apply filters and conditions.
Q: In DATA alert, can you edit an ADDED MEASURE?
A: If you mean if you can edit a measure once it has been created, yes you can do it after from the QA web console.
Q: Is it mandatory to have different machines for Qlik Sense and Qlik Alerting?
A: Not mandatory but best practice is to have them in separate machines.
Q: Can you loop through Selections to test condition on each?
A: Yes, using filters and more advanced conditions, you can find some examples in our Help Page.
Q: Since it's included in SaaS, does that mean there's no added cost?
A: Yes, exactly, for Qlik Sense Enterprise SaaS there is no extra cost, but it is only available for SaaS Enterprise, not in Qlik Sense Business.
Q: Can Custom notifications be used to send alerts in another language?
A: Yes, sure, it can be sent in any language as they are custom notification so you only need to put whatever text you like.
Transcript:
Extension cannot exceed a certain number of dimensions and measures in Qlik Sense.
The new dimension/measures do not get added to the hypercube and the object becomes blank.
Environments:
Qlik Sense Enterprise on Windows
This suggests that the extension was created with a low qWidth in the beginning.
Raise the qWidth value in the extension source and delete/add again the object to the sheet to be able to add more dimensions/measures as this will not reflect on objects already created.
More details in this community post: https://community.qlik.com/t5/Integration-Extension-APIs/Measures-Missing-from-HyperCube-Matrix/td-p/19621
It is not possible to use Qlik Sense Mobile SaaS with ADFS as the IdP either on iOS or Android.
While everything works fine with the browser, when using the mobile app, users are getting this error:
{"errors":[{"title":"State verification failed","detail":"State parameter not valid, try accessing
the tenant url directly","code":"STATE-
1","status":"401"}],
With Qlik Sense Mobile we currently support only a specific list of Identity Providers, as specified on the help site. We will be expanding this list regularly, as new IdPs will be tested and added to the list.
ADFS is currently an unsupported IdP.
Please, check regularly the above-mentioned help page to be informed about expanded IdP supported.
Use Safari on iOS or Chrome on Android for the time being.
