I like the concept behind the Oracle Enterprise Manager Hybrid Cloud Architecture to connect my on-premise OMS with targets in the Oracle cloud. The Agent communicates via SSH tunnel to target servers, no other ports than SSH 22 are open against the world wide web. An I was interested to find out, if the installation of such an agent works for other cloud providers than Oracle too.

Read MoreFrom the Command Line into the to the Oracle Cloud – the ORACLE-DBCS-CLI Utility
The Oracle ORACLE-DBCS-CLI utility is a command-line interface tool to manage the lifecycle of your Database as as Service instances in cloud.oracle.com. You can create and delete instances, verify and apply patches, scale your instances up and down and many more. The advantage is that you can work with configuration files. And I like to work with such files, if I need 10 instances with the same shape, I have only to search and replace the instance name – fire! The ORACLE-DBCS-CLI utility is available for Unix platforms at the moment. I have installed ORACLE-DBCS-CLI on a Oracle Linux 6.5, JDK version 1.7 or higher is required.

Read MoreDo you need a Mailserver for Testing Purposes? Communigate Pro!

CommuniGate Pro CommuniGate Pro is a groupware which supports a lot of solutions like SMTP, POP3, Webmail and many more. In this post I describe how you can easy install the software and configure the SMTP component in Oracle Enterprise Linux 6. The goal is to use CommuniGate Pro for the Enterprise Manager…
Read MoreHostname in Oracle Enterprise Linux 7 anpassen – hostnamectl
In Oracle Enterprise Linux 6 konnte man den Hostname beispielsweise mit Tools wie system-config-network oder durch editieren vom /etc/sysconfig/network File anpassen. In der Version 7 kann der Hostname mit dem Tool hostnamectl geändert werden. Ein Editieren vom Network-File funktioniert nicht mehr, der Hostname wird aus dem File /etc/hostname abgeleitet. Auszug aus den Oracle Enterprise Linux 7 Release Notes – https://docs.oracle.com/cd/E52668_01/E53499/html/section-bbw-bzj-4n.html: Nebst hostnamectl gibt es mit Tools für den NetworkManager wie nmtui und nmcli weitere Möglichkeiten, den Hostname anzupassen. Anzeigen vom Hostname mit hostnamectl Neben dem eigentlichen Hostname werden noch Zusatzinformationen der Plattform angezeigt. Das gute alte hostname Kommando funktioniert natürlich weiterhin.
