jmap command not found

Question

I\'m trying to use the jmap command on my CentOS server but it keeps telling me that the command was not found even though I have the JDK installed.

Answer 1

You should be able to find jmap in the java-1.8.0-openjdk-devel-debug, or java-1.7.0-openjdk-devel-debug, or java-1.6.0-openjdk-devel-debug packages on Redhat/Centos. To install it, run the following as root:

yum install java-1.8.0-openjdk-devel-debug

For completeness, here's the command to check which packages include jmap:

yum whatprovides '*/jmap'

Here's a sample output:
