问题
I am migrating a Worklight application from my development environment in Eclise to a Testing environment on Tomcat 7, with MySQL as my Worklight database.
I followed the instructions given @ Worklight Guide and IBM Guide for setting up MySql for Worklight.
When deploying via Worklight Console, the console deploys adapters without a problem, but while deploying the .wlapp files, there is a DB error:
[ERROR while deploying .wlapp of size 4.5MB ]
Failed to deploy application 'XXXXXXXX.wlapp'. : Parameter of prepared statement which is set through mysql_send_long_data() is longer than 'max_allowed_packet' bytes {prepstmnt 940490894 INSERT INTO APP_SYNC_DATA (appDeployableKey, deployable, deployableHash, lastPersistentPropertyChange) VALUES (?, ?, ?, ?)

回答1:
The error is pretty much straight forward. The deployment of the .wlapp files fails because the value of the property max_allowed_packet in MySQL is too low (by default it is 1MB).
It seems like the MySQL guide you've linked to misses some (important) steps.
Try these instructions:
- Locate the file
my.inibelonging to your MySQL installation - In it, find the section
[mysqld] - Underneath the section name, paste this:
max_allowed_packet=500M - Re-start the MySQL service
- Re-deploy the .wlapp files
Deployment should now pass.
