I am working on enable ssl for Oralce EPM11121 OHS server.
While after configuration, want to restart the OHS server. Found it can not be start and got below error message from ohs_component.log

Anyone know how to find the overlap one listen 19000? And make OHS server can be startup?
I already tried >lsof -i :19000 but it returns nothing. Any other method that can find the configuration might listen to 19000?
Finally find out where the wrong configuration.
I carelessly commented out 'Listen 19000' in file {EPM_ORALCE_INSTANCE}/httpConfig/ohs/config/OHS/ohs_component/ssl.conf
Should comment Listen.
# OHS Listen Port
# Listen 19000

I have installed my Spring Boot application at an Ubuntu version 18 server.
I use apache2 and lets encrypt to secure the application with SSL.
The application works fine in 95%, sometimes I get a HTTP 503 error at the client (Browser debugging view)
If HTTP 503 appears at the Browser/Client an entry is also made at apache2 log file which looks like this:

I found this thread:
We did some more investigation and found that the Apache setting that enables packets > 8192
(ProxyIOBufferSize 65536) was not going into effect because it was wrapped in an <IfModule
... > condition. (The module is loaded but we are investigating why the condition isn't
satisfied.) Tomcat 8.5 worked because it never sent packets larger than 8192, even though it
was allowed to, Tomcat 9 is sending bigger packets as it is configured to. With
ProxyIOBufferSize outside of the conditional, it is now working as expected.
My question now would be if it is possible that the size of ProxyIOBufferSize is to small and how can I adjust ProxyIOBufferSize in apache2 config file.
You can change ProxyIOBufferSize Directive of Module mod_proxy ref : https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxyiobuffersize
Edit proxy section of /etc/apache2/sites-enabled/000-default.conf :
<Proxy>
ProxyIOBufferSize 65536
</Proxy>
I use a Oracle WebLogic Server 12c and when I start it on Eclipse it shows this error, it does'nt allow me to log in localhost neither when I try to access it
from another computer in a different domain, in the log appears that the server is not reacheable.
This is the exception that appears in Eclipse.
This Exception occurred at Wed Nov 13 08:11:07 CET 2019.
weblogic.nodemanager.NMConnectException: Connection refused: connect. Could not connect to NodeManager. Check that it is running at localhost/127.0.0.1:5556.

And this is my StartBt script file, used to start the server and specify some preferences:

nmStart('AdminServer')
nmDisconnect()
I want to make it accesible, not only for local.
nmConnect('weblogic','AXLWL20040','localhost',**'5521'**,'base_domain','C:/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain','plain')
Port should listen to 5545.
You wrongly configure the ports. Your NodeManager listen on port 5540
ListenPort=5540
You try to connect to 5545
WLSTException:..Could not connect to NodeManager. Check that it is running at localhost/127.0.0.1:5545
I followed installation guide and deployment guide and I can access CKAN site but on port 5000, not on 8080.
What have I done wrong?

Changed everything back to how the deployment guide says.

Also tried changing the 127.0.0.1:8080 to *:8080 and tried public IP address (Amazon Elastic IP) and DNS address. None of them work.
ports.conf has listen 8080 (taken out listen 80)
wsgi script and nginx config as described in guide also.
I see the "Problem loading page" on Firefox visiting the root url on port 80 but visiting 8080 just hangs and both don't have HTTP response. I can still access CKAN on port 5000.
Amazon EC2 doesn't allow connections to port 8080 by default, so could open the port if you really wanted to access it externally.
However accessing CKAN via 8080 is only for testing that the apache deployment is working, so it makes no sense to make it available externally - you can test apache is working by ssh-ing to the box and using curl.
The CKAN deployment instructions continue by telling you to install nginx as a reverse proxy, exposing CKAN on the normal port 80.
Today I configured a basic tinyproxy.
I expected it to act as proxy for ubuntu repositories.
But when trying to download stuff from repositories I got this on tinyproxy log
CONNECT Mar 27 17:30:46 [20348]: Connect (file descriptor 9): [unknown] [192.168.2.30]
CONNECT Mar 27 17:30:46 [20348]: Request (file descriptor 9): GET http://br.archive.ubuntu.com/ubuntu/pool/main/t/tdb/python-tdb_1.2.12-1_amd64.deb HTTP/1.1

ERROR Mar 27 17:30:56 [20348]: opensock: Could not retrieve info for br.archive.ubuntu.com
INFO Mar 27 17:30:56 [20348]: no entity
I stuck on some misconcept. Do not tinyproxy send requests for outside servers directly?
I supllied an external proxy server to fix this

I'm trying to setup Hudson on a Windows server.
When I attempt to run Hudson with the command java -jar hudson.war, then I receive an error that the address is already in use for the HTTP listener.
I've confirmed that port 8080 (the default Hudson HTTP port) is not being used. I have also tried starting Hudson on another port (java -jar hudson.war --httpPort=8888) with the same error.
If I browse to http://localhost:8080, then I get an 'It works!' message on the web page. However, if I browse to http://localhost:8080/hudson, I receive a 404 error.
Here is log:

I downloaded the latest .war file from http://hudson-ci.org/download/war/, specified port 8888 instead of 8080, and now it works. Looks like there must be something running on port 8080 and the version that I had tried to use earlier than 1.381 had an issue.
