pyodbc.OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 17 for SQL Server]


Recently, I faced this error in our Docker-Container environment. All the necessary packages were already installed but still, I was facing this clueless error. I search a bit and after an hour and so I found the exact reason and solution for this error.

To know more about this error in detail. Please follow this Github thread.

Solution: It's because the server's certificate has too weak a key.

In case you are using Linux env directly/not the Docker one. Just edited /etc/ssl/openssl.cnf and change these 2 lines.

MinProtocol = TLSv1.0
CipherString = DEFAULT@SECLEVEL=1

In case you are also using a container, please add these three lines to your Docker file.

RUN chmod +rwx /etc/ssl/openssl.cnf
RUN sed -i 's/TLSv1.2/TLSv1/g' /etc/ssl/openssl.cnf
RUN sed -i 's/SECLEVEL=2/SECLEVEL=1/g' /etc/ssl/openssl.cnf

Thanks!! Enjoy Programming!

Scenario :  I want to create a one2one relation between two objects of openerp hr.employee and hr.employee.medical.details What I should do  i. Add _inherits section in hr_employee class ii.

How to draw Dynamic Line or Timeseries Chart in Java using jfreechart library?

Today we are going to write a code to draw a dynamic timeseries-cum-line chart in java.   The only difference between simple and dynamic chart is that a dynamic event is used to create a new series and update the graph. In out example we are using timer which automatically calls a funtion after every 1/4 th second and graph is updated with random data. Let's try with the code : Note : I had tried my best to provide complete documentation along with code. If at any time anyone have any doubt or question please post in comments section.
