Introduction

• A Shell script to collect the jstack, pmstack and heapdump on running process
• Helps to collect dumps at regular intervals for 'n' iterations

Usecase / Scenario

• The tool can be used to collect thread/heap dumps from Java applications that are having issues like slowness, hangs and performance

Features

• Does not require any credentials to run this command
• Only INFA_HOME variable has to be set.
• On Windows, ensure this command is invoked as a system account user if the Informatica service is started as Windows service (Refer to KB 142454)

Usage / Example

1. setenv INFA_HOME /PATH/TO/INFAHOME
2. infadump.sh is available in  INFA_HOME/tools/debugtools/infaDump/
3. Usage: infadump -p <pid> | -c <corefilename> [ -o {jstack,heapdump,pmstack}] [-d <outputdir>] [-z <zipfilename>] [-i <no.ofiterations>] [-r <runinterval>] [-s] [-h]
