Installing Bonita 7.11 and Configuring it with MySQL

Q&A
1

Hi I'm new to Bonita. I installed BonitaStudioCommunity edition and made necessary configurations as mentioned in https://documentation.bonitasoft.com/bonita/7.11/database-configuration . It mentions the steps of making changes in /setup/database.properties and running start-bonita.bat and I'm getting initialization errors. I've increased max_allowed_packet in MySQL config too. Since the studio fails to activate tomcat server, I downloaded Runtime bundle separately and tried again, and I get the same initialization error. But I can see the tables and necessary data are getting populated to the MySQL DB. The undermentioned is the error-log I'm getting. If anyone can help me to fix it, that would be great.

Hi,

Studio comes with an embedded engine using h2 database, it is not supported to plug another database for this environment.

You need to install a bundle.

The exception you get talk about packet size, there is a specific paragraph in the doc about packet size and MySQL. Did you see it ?

Maximum packet size

MySQL defines a maximum packet size on the server side. The default value for this setting is appropriate for most standard use cases. However, you need to increase the packet size if you see the following error: Error: 1153 SQLSTATE: 08S01 (ER_NET_PACKET_TOO_LARGE) Message: Got a packet bigger than ‘max_allowed_packet’ bytes
You need to update the file my.ini (for Windows) or my.cnf (for Linux) to avoid the ER_NET_PACKET_TOO_LARGE problem. Look for max_allowed_packet setting and increase the value.

For more information, see the MySQL website.

I'm not particularly sure anything on bundle. Please put me the documentation link if you have. Also for your info my initial max_allowed_packet was 16M, but i increased upto 128M when I got the above error. What is the max size do you recommend?

It's in the same doc article.

In the log the packet is 4,486,717 bytes (about 4.5 Mo) and the max is 1,048,576 bytes (1Mb).

So I suggest setting max_allowed_packet=128M  in my.cnf or my.ini
