DB2 - Problem description

Problem IC96251 Status: Closed

BATCH EXECUTION INTRODUCES INTERNAL COMMIT (EVEN WITH AUTOCOMMIT OFF)

product:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problem description:
When using CLP commands even with AUTOCOMMIT OFF combined with 
batch execution, the batch run will introduce an internal commit 
which might result in unexpected behaviour as anything that was 
executed previous to the batch will commit implicitly regardless 
of the setting of autocommit. 
 
Simple test case: 
 
db2 connect to sample 
 
cat  t_maria 
create table AAAAABBBBB(c1 int); 
 
 
1. db2 +c "create table AAAAAA(c1 int)" 
2. db2 +c -stf t_maria 
3. db2 rollback 
 
NONE of the tables should exist on the system after the 
rollback, but the execution with the batch file is doing a 
commit implicitly, so the first table creation gets committed. 
 
db2 list tables for all | grep -i AA 
AAAAAA                          MARIAJ          T
