Hi,
I am trying to install the Enterprise Manager into a VBox running Oracle Linux 8. This is my second attemd, and the first attempt worked relatively smoothly.
Now on a roleback und retry to install it, I run into an odd error. Since it is a testing system, I install it using the "Simple Install" Option.
The error occurs in the step between "Configuration Details" and "Database Prerequisite Check".
After giving a password for sysman, entering the short name of the VM, the port, service and sys password, the error occurs on clicking next.
First in the console from where the em13500_linux64.bin has been started a Java error is displayed:
oracle.sysman.install.oneclick.queries.AgentPortHandler$PortHandlerException: Der freie Port Enterprise Manager Central Console Port aus dem Standardbereich 1830 bis 1849 konnte nicht zugewiesen werden. Geben Sie einen Port aus dem genannten Bereich frei, und wiederholen Sie den Vorgang. (translates roughly to: The free port Enterprise Manager Central Console Port from the default range 1830 to 1849 cannot be assigned. Free a port from the aforementioned range and retry.)
After that a pop up shows up, stating: "Sie haben Port -1, -1, -1, ... für mehr als eine Komponente eingegeben. Geben Sie einen eindeutigen Port für eine Komponente an." (translates roughly to: You entered port -1, -1, -1 ... for more than one component. Give a unique port for a component.).
Confirming that dialogue results in another pop up: "Enterprise Manager erfordert, dass mehrere Ports zugeordnet werden, um die interne Kommunikation zwischen den Systemkomponenten zu vereinfachen und den Zugriff auf die Konsole über einen Browser zu ermöglichen.<p>Das installationsprogramm kann die Ports auf diesem Host nicht binden. Prüfen Sie die Konfiguration des Hostnamens und der IP-Adresse auf diesem Host. Nachdem das Problem gelöst wurde, starten Sie das Installationsprogramm erneut und wiederholen den Vorgang." (translates roughly to: EM requires the assignement of several ports to facilitate the internal communication between server components and to allow the access of the console using a browser.<p>The installation programm cannot bind the ports on this host. Check the configuration of the hostname and ip address on this host. After solving the problem restart the installation programm and retry the process.)
Sorry that the texts are in German, I have no clue how to start the installer in english.
My current configuration is:
service firewalld is stopped - this should allow the assignment of any port.
/etc/hostname contains oracle.csierks.local
/etc/hosts contains 127.0.0.1 oracle oracle4 oracle.csierks.local oracle4.csierks4.local
The error occurs independent of the value I give for the database host, oracle or oracle.csierks.local.
Any hint on how to solve this error?
Cheers
Carsten
