I am using Oracle HTTP Server.
I would like to ask about my server log file. I saw an ERROR in my log file example like this:
[OHS] [ERROR:32] [AH00127] [core] [client_id: 10.10.10.10] [host_id: example] [host_addr: 10.10.10.10] [pid: 111111] [tid: 111111] [user: web] [ecid: 111111] [rid: 0] [VirtualHost: example.com.tr:5555] (36)File name too long: AH00127: Cannot map GET /example/...
This Error does not occur another Load Balancer. But I get in Oracle HTTP Server in a specific context path.
I know the solution for change the Linux file System limit from "255". But don't want to change the whole server for this particular error.
Any idea to fix this problem?

Using Oracle JDBC driver with TNS-alias instead of host:port:SID a'la
jdbc:oracle:thin:#TNS_ALIAS
you may get this error message
java.sql.SQLRecoverableException: I/O-Error: Unknown host specified
while calling
java.sql.DriverManager.getConnection
But there is no problem with the hostname specified by TNS-alias.
Sadly this error message does not point to the real reason:
The error occurs if driver cannot find the tnsnames.ora config file.
Solution
You have to ensure that system-property "oracle.net.tns_admin" is set before connecting and points to the directory containing the tnsnames.ora.
I have upgraded a SonarQube server from 6.0 to 6.7.2. Everything is fine, except that, after logging in as user "admin" and navigating to tab Administration, clicking on subtab System yields an error message
An error has occurred: please contact your administrator.

Caused by: java.io.IOException: Server returned HTTP response code: 503 for URL: http://10.145.61.55
The IP address is that of the server. There is no mention of any port in the error message, I don't know if this has any relation with the error.
It seems that the Web component cannot access the Compute Engine component. However nothing particular was found in file ce.log which ends with a trace Compute Engine is operational.
I followed the short migration guide in https://docs.sonarqube.org/display/SONAR/Upgrading.
Environment: Linux, JDK 8, Oracle DB
Does anyone as a clue? Many thanks in advance.
For whoever who might stumble on the same issue: it was an error in my proxy configuration. Increasing the logging level by setting sonar.log.level=DEBUG in file sonar.properties yielded the following new traces in file web.log:

The proxy was redirecting the Compute engine URL http://127.0.0.1:40413/systemInfo to http://10.145.61.55.
The solution was to add 127.0.0.1 to http.nonProxyHosts in file sonar.properties.
How to MonetDB log settings.
I want to change the log level of "merovingian.log".
I want to output the ERROR and WARN the merovingian.log.
But now merovingian.log is outputting only MSG log.
2016-07-22 18:12:03 MSG merovingian[7825]: proxying client x.x.x.x:51609 for database 'test' to mapi:monetdb:///var/MonetDB/dbfarm/test/.mapi.sock?database=test
2016-07-22 18:12:03 MSG merovingian[7825]: target connection is on local UNIX domain socket, passing on filedescriptor instead of proxying
OS is "CentOS 6.4",
MonetDB version is "MonetDB-11.19.7".
Any advice how to solve this problem?
No fine-tuning is provided in where log information ends up.
When I entered Oracle Application Server Control panel, an error message was appeared "Too few bytes (-1) received from OPMN response". It doesn't allow to do any deployment. How can I fix this error?

After a long search process, I find that my error is related with owner permissions on oracle server. oracle user manages the instances so files under oracle/ folder must have oracle owner permissions. If you enter with root or other user and change some file permissions by running or rewriting them especially config files under j2ee/home/persistence, opmn/conf, opmn/bin, oracle user can not execute that files. I set files owner permissions with oracle user and restart the server, error was gone.
I'm trying to run gradlew to build some code that had been supplied to me. The source is the ZIP download from here and all I've done is open a command prompt, cd to that folder and run gradlew.bat.
I've had this work on my crash'n'burn machine but I can't get it working on my main dev machine. The dev machine sits behind a proxy which requires authentication, the other machine doesn't - they're at different locations.
Originally, I got:
Exception in thread "main" java.net.UnknownHostException: services.gradle.org
From this, to gradle.properties, I added:
systemProp.http.proxyHost=192.168.x.y
systemProp.http.proxyPort=80
systemProp.http.proxyUser=myuserid
systemProp.http.proxyPassword=mypassword
and ran it again and got:

For info, if I try an incorrect password or ID, I get:
Exception in thread "main" java.net.ProtocolException: Server redirected too many times (20)
so I think that rules out incorrect ID. Anyone have any ideas what I can try?
I don't know exactly what caused the connection reset but I tried again several times, in case it was transient and, after some time, the response changed to:
Exception in thread "main" java.io.IOException: Server returned
HTTP response code: 403
Suspecting our security systems, I tried to download the file using a browser and received a message from one of the security boxes saying it had been blocked because it contained a .bat file: a regular occurrence.
Look in your build.gradle and gradle.properties and edit 'https://' to 'http://' in all links
I still got this issue today. Different company has different proxy settings.
after investigate, it worked for me:
org.gradle.daemon=true

systemProp.https.proxyUser=[user name]
systemProp.https.proxyPassword=XXXXX
systemProp.https.nonProxyHosts= localhost
