THE REMOTE CONNECTION'S ISOLATION LEVEL IS SERIALIZABLE WHEN USING SQL
SERVER WRAPPER 2PC FEATURE

product:
DB2 FOR LUW / DB2FORLUW / A10 - DB2
Problem description:
SQL Server wrapper uses the default isolation serializable when 
using federated two phase commit. 
 
Here is the reproducing scripts: 
db2 => set passthru <your_server>; 
 
db2 => select transaction_isolation_level from 
sys.dm_exec_sessions where host_name = '<your_federation_host>'; 
 
transaction_isolation_level 
--------------------------- 
                          2 
 
  1 record(s) selected. 
 
db2 => set passthru reset; 
DB20000I  The SQL command completed successfully. 
 
db2 => alter server SQLSERVER options(set DB2_TWO_PHASE_COMMIT 
'N'); 
DB20000I  The SQL command completed successfully. 
db2 => 
db2 => set passthru <your_server>; 
DB20000I  The SQL command completed successfully. 
db2 => select transaction_isolation_level from 
sys.dm_exec_sessions where host_name = '<your_federation_host>'; 
 
transaction_isolation_level 
--------------------------- 
                          2 
 
  1 record(s) selected. 
 
db2 => set passthru reset;
