1. Select,insert and update works in my perl script.
2. When i try to do reset monitor all i am getting the following error message
"<!-- warning: DBD:B2::db do failed: [IBM][CLI Driver][DB2/AIX64] SQL0104N An unexpected token "monitor" was found following "reset ".
Expected tokens may include: "JOIN «joined_table»". SQLSTATE=42601 -->
"

It's not possible to run DB2 commands through the DBD, just SQL statements.
