Run SOAP the first time SOAP Service Manager: Unable

This is just an informational warning, not an error. The file
referenced does not exist but is created for you.
HeapDumpOnOutOfMemoryE
rror
This is not an error, and is not logged at ERROR level. This is
a Java VM option that enables creating a heap dump when
the VM encounters and OutOfMemoryError. This dump is
useful when diagnosing memory issues.

Possible DNS resolution issue. Test server connectivity using

Application server does not
start
1
Check if the license has expired. If so, resolve.
2 Verify minimum hardware requirements. If there are not
enough RAM resources, the servers cannot start.
3 Contact support if your server still fails to start.
Too many open file errors
on Linux
High volume/activity systems may need tunning by
configuring file handle maximums in the /etc/security/
limits.conf file and making sure that the following are at
minimum 65535:
test soft nofile 65536
test hard nofile 65536
test soft nproc 65536
test hard nproc 65536
Here, test is the installing user login.
Set these limits higher for more heavily used systems. You can
check/set file handles temporarily using the ulimit -H/Sn
command. For example:
$ ulimit -Hn
$ ulimit -Snunning.
Caution: If you enter ulimit -a in a shell, open files should
not be 1024, and User Processes should not be 1024. These
are defaults that
must be changed. If you do not have enough
file handles, an error appears saying not enough threads are
available for the application.
