How to check OHS version? You can use the Oracle EM console, CLI, or the LD_LIBRARY_PATH environment variable to check the latest version of Oracle HTTP Server. In the CLI, you can check the latest version by typing “ohs” in the command-line prompt. If you don’t have an EM console, you can find the version in the ORACLE_HOME environment variable.

To find out which version of Oracle HTTP Server is installed on a machine, use the EM console or CLI. You can also check the version of Oracle HTTP Server by checking the ORACLE_HOME environment variable or the LD_LIBRARY_PATH environment variable. Generally, it is a good idea to check the version before installing any patches or other software. If you aren’t sure, you can try the EM13cR1 security checkup script that is available at GitHub.

Traditionally, wls_port and ohs_port were used to access Oracle WebLogic Server directly, but now, with Fusion Middleware Control, you can manage java components that run on WebLogic. Both of these tools are installed on the WebLogic Admin Server, and they communicate with each other over HTTPS. The CERTS are generated during the registration process with the WebLogic Server.

EM 12c has the capability of secure-locking the OMS. In this mode, only agents that use a secure HTTPS port communicate with each other. This feature also prevents man-in-the-middle attacks from being possible. To prevent man-in-the-middle attacks, you should ensure that access to the EM console is locked. To prevent hackers from gaining access to the system, make sure that the SSL/TLS over HTTPS protocol is enabled.

As EM 12c supports managed credentials and EUS, you may want to use a VPN connection. A VPN connection can protect your system from attacks and maintain compliance. In addition, you should use an SSL/TLS certificate when connecting to EM over a VPN. You can also use the Cloud Control Mobile app, which is available in the iTunes store. It supports VPN connections and works well with the EM 12c console.

Operational security in EM 12c focuses on authentication, authorization, and auditing. These features ensure that users are authenticated, that access to secure resources is limited, and that high assurance of nonrepudiation is guaranteed. The following sections explain these features and how they work. If you want to make sure that your data is secure, make sure that you read and understand the security policy of Enterprise Manager.

Security alerts

If you are checking your OHS version, you might receive a message asking you to apply a security patch. The message explains that this new security patch is needed to protect against vulnerabilities in Apache Log4j. These vulnerabilities can be remotely exploited without authentication. This security alert is important to apply, as the previous version was not updated for the new vulnerability. You can also choose to receive only critical alerts.

You can view security patches for eligible Oracle products in the Security Alert program. The security patches are only available for products that are covered by Premier Support or Extended Support. Consequently, it is recommended that you plan your product upgrades ahead of time. But if you cannot afford to wait for Oracle to release an upgrade, you can simply use the Security Alert program to receive updates. Then, you can download the security patch and update your Oracle software.


To check the version of Oracle HTTP Server, go to the OHS_INSTANCE/bin directory and locate the “httpd” command. To find out the latest version, amend the “httpd” command with the -v option. The OHS HTTP Server is an application that connects to backend servers and serves web pages. This application is part of Oracle Fusion Middleware. It can be used for Web browsing and hosting dynamic pages and applications.
