jstat not found even though we installed java JDK

We installed the following RPMs (part of the Java development kit), on Red Hat Enterprise Linux 7.5: $ rpm -qa | grep jdk java-1.8.0-openjdk-headless-1.8.0.171-8.b10.el7_5.x86_64 java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64 copy-jdk-configs-3.3-10.el7_5.noarch but we can't find jstat which should be on the following path: /usr/jdk64/jdk1.8.0...../bin/jstat What is wrong here? Is jstat part of the installed RPMs above or do we need another java installation? $ which java /usr/bin/java
