The following host-level issues can cause installation problems.
Updates. Have you applied the recommended updates (patches)?
Disk Space. How is the disk partitioned, and to what partitions do installation directories point? The installation directories /var/sadm and /etc/opt, or the non-default directories that you specify, need sufficient disk space.
Network Ports. During configuration, you supply port numbers for Java ES product components. Check the following:
Examine the standard port numbers in the file /etc/services .
Look at the summary log file to compare your settings with the standards. Did you mistype a port number or set one server to the port that is typically used for another?
Use the command netstat -a to view current port use on the system. Did you assign a port number that was already in use?
IP Addresses. During configuration, you specify IP addresses. Check that you entered the correct IP addresses. These are some questions to resolve:
Does this system have multiple network interfaces, each with its own IP address?
In a high availability configuration, did you specify the IP address of the logical host or the IP address of a cluster node?
