Oracle Enterprise Manager Ops Center includes the OCDoctor utility, a tool that can check systems for installation prerequisites, troubleshoot issues, and tune systems for Oracle Enterprise Manager Ops Center. This chapter discusses the use of the OCDoctor.
The following features and topics are covered in this chapter:
The OCDoctor is a tool that can provide a variety of information about Oracle Enterprise Manager Ops Center and current or potential Enterprise Controller, Proxy Controller, and Agent Controller systems.
The OCDoctor is located in the
/var/opt/sun/xvm/OCDoctor directory on the Enterprise Controller system. You can copy the OCDoctor to other systems or download it from Oracle. Once you have copied it onto a system, you can perform preinstallation checks, troubleshoot issues, and check for OCDoctor updates.
If you are operating in disconnected mode, or if you want to install the latest version of the OCDoctor on a new system, you can download the latest version from Oracle.
On an Internet-facing system, navigate to
http://java.net/projects/oc-doctor/downloads and click the OCDoctor-LATEST.zip download.
Move the downloaded file to the target system.
Unzip the file.
If the target system is an existing Enterprise Controller, replace the contents of the /var/opt/sun/xvm/ocdoctor directory with the contents of the zip file.
You can use the OCDoctor to verify that systems meet the prerequisites for an Oracle Enterprise Manager Ops Center installation, get a benchmark score, or check the system's connectivity.
Change to the
OCDoctor.sh script with one of the following options:
--ec-prereq: Verifies that the system meets the prerequisites for an Enterprise Controller installation.
--proxy-prereq: Verifies that the system meets the prerequisites for a Proxy Controller installation.
--agent-prereq: Verifies that the system meets the prerequisites for an Agent Controller installation.
--performance: Checks the speed of the system and provides a Benchmark Time (BT) score. You can use a BT score to estimate how many assets a system can effectively manage. You should use this option when the system is idle.
--check-connectivity: Verifies that the system has network connectivity by connecting to My Oracle Support and downloading two test files.
