ODBC Connectivity to MySQL 8

[mike_at_mla]

Replicate Server:  Red Hat 7

Target: MySQL Community 8.0.28 (upgraded from MySQL 5.7)

All parameters on the server have been set to utf8mb4 (as before)

In the logs, Qlick is pointing to the following ODBC Driver:

Using default driver manager 'unixODBC', path is '/opt/attunity/replicate/lib/libodbc.so.2.0.0'

In the logs, getting this error:

RetCode: SQL_ERROR  SqlState: 07006 NativeError: 0 Message: [MySQL][ODBC 5.2(w) Driver][mysqld-8.0.28]Source character set not supported by client [1022502]  (ar_odb
c_stmt.c:3467)

I don't want to install an RPM (system wide) if Attunity(qlik) is pointing to it's own driver.

Q1. Do I need to update the driver under the attunity directory ?

Q2. If so, how do I do this ?

Q3. Will this be backward compatible as I have another replication going for MySQL 5.7

Thanks..

To add to this.. I ended up installing the ODBC 8 driver on the server..

The odd thing is, the above reference saying it's using a driver under it's own directory still hold true, but after installing the latest V8 driver, the logs are showing that it's using

Going to connect to ODBC connection string: DRIVER={MySQL ODBC 8.0 Unicode Driver}

so I'm a little confused on how all this work..

On a side note, the original error has disappeared.. but I would like to know what's happening.

Hi @mike_at_mla ,

MYSQL Driver depends on the Replicate version.

Below is the info from the 2021.11 user guide:

Client prerequisites

Install MySQL ODBC Unicode Driver 64-bit on the Replicate Server machine.

Information note

Only these driver versions are supported:

• 5.3.11  to 5.3.13
• 8.0.23 to 8.0.25

By default Replicate 2021.11 look for MYSQL 8. x Unicode driver. If you want to point out the specific driver version example 5. x please follow the steps provided in the below community article:

Thanks,
