DB2 FOR LUW / DB2FORLUW / 970 - DB2

The "UOW log space used" value can grow to impossible high
values when the application is running in an XA environment.

This is because the counter value will not get reset when doing
the XPREPARE, and the counter will just increase.

e.g. the following java code will cause the counter to increase,
although there is a commit that should reset the counter to 0.

public class Main {

    public static void main(String[] args) {
        try{
            DB2XADataSource db2XADataSource = new
DB2XADataSource();
            db2XADataSource.setDatabaseName(args[0]);
            db2XADataSource.setUser(args[1]);
            db2XADataSource.setPassword(args[2]);

            XAConnection xaConnection =
db2XADataSource.getXAConnection();
            XAResource xaResource =
xaConnection.getXAResource();
            Xid xid2 = new MyXid(new byte[]{0x20}, new
byte[]{0x22});
            for(int i=0;i
