Problem

I create a connected datastore object in a servlet and then pass the connected datastore object to a method in a different servelet to perform an operation. I frequently get DKException "[IBM][CLI Driver] CLI0125E Function sequence error. SQLSTATE=HY010 "

Cause

If the same datastore object is not property synchronized in a multithreading scenario, the following error is likely to occur when performing operations on the datastore:

DKException
[IBM][CLI Driver] CLI0125E Function sequence error. SQLSTATE=HY010

Solution

This is a classic symptom of a threading problem. Most likely, the same datastore instance is used by multiple threads at the same time.

Either strictly synchronize your access to the datastore object or have each thread use its own separate connected DKDatastoreICM object.

Using separate datastore objects is the safest solution.
