3.1 Preparation: Installing DTrace-Enabled Applications

DTrace-enabled versions of user-space applications are made available via the playground repository of the Oracle Linux Yum Server (http://yum.oracle.com/repo/OracleLinux/OL6/playground/latest/x86_64/). These applications have been instrumented to contain statically defined DTrace probes. You can find details about the probes for PHP at http://php.net/manual/features.dtrace.php.


The packages that are provided in the playground repository are intended for experimentation only and you should not use them with production systems. Oracle does not offer support for these packages and does not accept any liability for their use.

To enable access to the playground channel on Oracle Yum Server, create an entry such as the following in /etc/yum.conf or in a repository file in the /etc/yum.repos.d directory:

name=Latest mainline stable kernel for Oracle Linux 6 ($basearch) - Unsupported 

To enable the channel, set the value of the enabled parameter for the channel to 1. You can then use yum to install the packages, for example:

# yum install php55
