I'm having trouble getting Database Control up and running in an Oracle Database 10g installation in RHEL4 Linux. I consistently see errors like these when I try to create or recreate the repository using emca:
SEVERE: Failed to allocate port(s) in the specified range(s) for the following process(es): JMS [5540-5559],RMI [5520-5539],Database Control [5500-5519],EM Agent [3938] | [1830-1849]

When I check these port ranges with netstat or lsof, nothing is running on those ports, and I can't figure out why Oracle can't work with them. I've even disabled iptables completely to try again, but this has no effect.

When I try to set port values manually (emca -reconfig ports ...), I get "Database Control is not configured for this database."

When I configure Database Control (emca -config dbcontrol db), I get the port allocation error. It seems to be a vicious cycle.

Thanks for any ideas you may have.

did you grep your ports with
netstat -i |grep <port> was that free?

Yes, I checked all active port ranges with netstat -na, and none of the ports Oracle wanted to allocate were open Sad

All three commands fail with "SEVERE: Database Control is not configured for this database."

Yup, already added those parameters, and followed up with a "sysctl -p" to implement the changes.

I have de/re-installed four or five times now, each time trying different things (creating the database manually, creating it with the DBCA during installation, etc.), and each time the end results has been exactly the same, same errors and everything else.

Maybe this is too late to be of help-- But deesto's problem is symptomatic of the machine's IP address being out of sync with the IP address that is registered with the DNS server. It looks like you are on Unix of some kind, so try this:

1. Check your hostname:

$ hostname
foo.example.com


2. Find out if your /etc/hosts file has an entry matching this hostname:

$ cat /etc/hosts
10.10.10.5 foo.example.com


3. Find out what your hostname is registered as in DNS:

$ nslookup foo.example.com

...or...

$ host foo.example.com
foo.example.com has address 10.10.10.6


Make sure the two IP addresses are the same and then try recreating the repository.

$ emca -config dbcontrol db

Better late than never! Wink I'd given up on this for a while, but your advice seems sane. If I get a chance to try again, I'll report back. Thank you.

This thread seems to be pretty old, but the following bit of knowledge may be useful to consider:
The other day I've faced the same issue and the solution was hidden in file /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
ip-address hostname hostname.domain-name.local
127.0.0.1 hostname localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6


The reason was in incorrect ip-address, it was different from actual hostname ip address. I changed it to correct value and was able to configure EM.
