My problem is pretty much the same as here
The problem is that I am using dashDB which runs as a service in IBM Cloud (formerly known as bluemix), so I don't have access to the same administrative tools some DB2 DBA has access to (AFAIK).
So I have a simple table, but when I try to add a column, I get this error
SQL0911N: SQL0911N The current transaction has been rolled back because of a deadlock or timeout. Reason code "68". SQLSTATE=40001 [IBM][CLI Driver][DB2/LINUXX8664] SQL0911N The current transaction has been rolled back because of a deadlock or timeout. Reason code "68". SQLSTATE=40001
I've stopped all other DB activity such as other select statements, and I've tried using eclipse JDBC-based DB IDE instead of the web-based administrative DashDB provided by IBM Cloud (just because its authentication session just ends too quickly) without success.
