Introduction

Ignite connects to a DB2 database using a JDBC driver. Ignite may hang when monitoring DB2 or cause memory leaks on the DB2 instance. Upgrading the DB2 JDBC driver that Ignite uses may solve these issues. Specifically, we have seen the following error which is a known bug in the DB2 JDBC driver with Ignite:

 

JAVA EXCEPTION - ILLEGALSTATEEXCEPTION: TIMER ALREADY CANCELLED

Environment

  • All versions of Ignite

Solution

Upgrade the JDBC driver. To download a new driver, this website provides links to all versions:
 

Instructions

Download the driver for IBM Data Server Driver for JDBC and SQLJ. Here are instructions using the DB2 9.5 FP10 driver that has helped at several customers:

 

  1. Download the driver from http://www-01.ibm.com/support/docview.wss?uid=swg21363866
  2. Shutdown Ignite.
  3. Replace the following files by the newly downloaded versions. This example shows the Windows directories, but the UNIX or Linux directories are similar. For example: <ignitehome>/iwc/tomcat/webapps/iwc/WEB_INF/lib:</ignitehome>
    • ​C:\Program Files (x86)\Confio\Ignite PI\iwc\tomcat\webapps\iwc\WEB-INF\lib\db2jcc.jar
    • C:\Program Files (x86)\Confio\Ignite PI\iwc\tomcat\webapps\iwc\WEB-INF\lib\db2jcc_license_cu.jar
  4. Restart Ignite.
