SQL connection error after upgrade to CloudStack 4.3.0

I just upgraded a small cluster of mine from CloudStack 4.2.1 to 4.3.0 and after installing the packages on my Ubuntu system the management server wouldn’t start due to a SQL error:

2014-03-25 20:52:13,643 INFO  [c.c.u.d.T.Transaction] (main:null) Is Data Base High Availiability enabled? Ans : false
2014-03-25 20:52:13,736 ERROR [c.c.u.d.Merovingian2] (main:null) Unable to get a new db connection
java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/cloud?autoReconnect=true&prepStmtCacheSize=517&cachePrepStmts=true
	at java.sql.DriverManager.getConnection(DriverManager.java:635)
	at java.sql.DriverManager.getConnection(DriverManager.java:195)

I quickly remembered a licensing issue around JDBC which delayed 4.3.0 and I was right. The management server was missing the right JAR/package for the SQL connection.

A quick apt-get install fixed it:

$ sudo apt-get install libmysql-java

This should have been a dependency of the ‘cloudstack-management’ package, but that somehow slipped through. I already applied a patch in the master branch and I’ll make sure it gets into 4.3.1 and 4.4.0.

So if you are running Ubuntu and are upgrading to CloudStack 4.3.0 and run into this issue, simply install the package and it’s fixed.
