I saw that one of our tools uses a ConsoleAppender to System.err next to System.out in it's log4j configuration. Fragments of the configuration:
<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
<!-- Log to STDOUT. -->
<param name="Target" value="System.out"/>
....
<appender name="CONSOLE_ERR" class="org.apache.log4j.ConsoleAppender">
<!-- Log to STDERR. -->
<param name="Target" value="System.err"/>
In Eclipse this results in double messages to the console, so I believe that is of no use, right?
On the Linux server I see only one message to the PuTTY console, so where would that System.err message go to?
It can be of use depending on how the standard and error outputs are redirected. Often the standard output is muted (e.g. redirected to /dev/null) so the error output is the only way to actually display error messages.
I suspect that PuTTY actually does that - it would be very unusual to mute stderr but not stdout. I guess that your CONSOLE_ERR is set to ERROR or WARN level. In this case, you could check with PuTTY whether only error messages are displayed or all of them, to decide which appender's output you are actually seeing.

at the beginning of the project we worked with Corda Opensource, and we used the command line argument logging-level=WARN to change the log level of the nodes.
When we started using Corda Enterprise, we noticed that a details-node-.log file was created. It is a log file that grows fast and is at TRACE level.
Our question: can the log in this file affect the performance of our cordapps and can we change the level of this log or disable it?
Corda Enterprise adds that logger which is not present in Open Source Corda.
The only impact I can see for a CordApp could be probably the lack of space on the server, so if in your case this log file becomes too big too quickly, it would be a good idea to configure it to avoid possible problems.
You can override the log4j configuration file and give it as input to the jar like this:
java -jar Dlog4j.configurationFile=new-log-config.xml <en-service>.jar
It is standard log4j, so you can also configure the rollover period and the size.
For reference, you can also take a look to this log4j.xml in open source Corda to see how the loggers are configured.
So, can probably override the logger you're concerned about with the following:
<?xml version="1.0" encoding="UTF-8"?>
<Properties>
...
<Property name="detailLogLevel">TRACE</Property>
</Properties>
<Appenders>
...
<RollingRandomAccessFile name="Detailed-RollingFile-Appender"
fileName="${log-path}/details-${log-name}.log"
filePattern="${archive}/details-${log-name}.%date{yyyy-MM-dd}-%i.log.gz">
<Policies>
...your policies...
</Policies>
<DefaultRolloverStrategy>
...your strategy...
</DefaultRolloverStrategy>
</RollingRandomAccessFile>
</Appenders>
<Loggers>
...
<Logger name="DetailedInfo" additivity="false" level="${detailLogLevel}">
<AppenderRef ref="Detailed-RollingFile-Appender"/>
</Logger>
</Loggers>
I have deployed WSO2ISasKM with WSO2APIM and I'm struggling to get the configuration right.
I can see there are a lot of scripts in the ../dbscripts folder. However, since I only share config+governance registry and userdb I created 2 dbs in which I only ran the script wso2is-km-5.7.0\dbscripts\postgresql.sql that created UM_ and REG_ tables. I am keeping the local registry in the WSO2CARBON_DB (H2). Is this correct?
I don't really make any use of scripts about IDENTITY and CONSENT that are shipped with the wso2IS binaries. Where should those scripts be launched?
I'm asking because there are some strange behaviour and errors about content in my logs.
This is how i configured the registry.xml of both IS and APIM:
<currentDBConfig>wso2registry</currentDBConfig>
<readOnly>false</readOnly>
<enableCache>true</enableCache>
<registryRoot>/</registryRoot>
<dbConfig name="wso2registry">
<dataSource>jdbc/WSO2CarbonDB</dataSource>
</dbConfig>
<dbConfig name="sharedregistry">
<dataSource>jdbc/WSO2REG_DB</dataSource>
</dbConfig>
<remoteInstance url="https://fqdn of the IS/APIM:9443/registry">
<id>sharedreg</id>
<cacheId>reg_db_owner#jdbc:postgresql://carbondb.postgresql-wso2.com:5432/wso2_carbon_shared_reg</cacheId>
<dbConfig>sharedregistry</dbConfig>
<readOnly>false</readOnly>
<enableCache>true</enableCache>
<registryRoot>/</registryRoot>
</remoteInstance>
<mount path="/_system/governance" overwrite="true">
<instanceId>sharedreg</instanceId>
<targetPath>/_system/governance</targetPath>
</mount>
<mount path="/_system/config" overwrite="true">
<instanceId>sharedreg</instanceId>
<targetPath>/_system/config</targetPath>
</mount>
This is how datasources got added in master-datasources.xml
<datasource>
<name>WSO2REG_DB</name>
<description>REGDB ON POSTGRES</description>
<jndiConfig>
<name>jdbc/WSO2REG_DB</name>
</jndiConfig>
<definition type="RDBMS">
<configuration>
<url>jdbc:postgresql://carbondb.postgresql-wso2.com:5432/wso2_carbon_shared_reg</url>
<username>wso2</username>
<password>wso2</password>
<defaultAutoCommit>true</defaultAutoCommit>
<driverClassName>org.postgresql.Driver</driverClassName>
<maxActive>50</maxActive>
<maxWait>60000</maxWait>
<testOnBorrow>true</testOnBorrow>
<validationQuery>SELECT 1</validationQuery>
<validationInterval>30000</validationInterval>
</configuration>
</definition>
</datasource>
The UM_DB entry is identical but it point to another database.
I also noticed that for REG_DB and UM_DB, with Postgresql-11, I have to set the defaultAutocommit must be set to true to avoid error in writing the registry.
Can you also explain what are the purpose of IDENTITY and CONSENT related tables?I read the docs but couldn't understand the practical use of them.
Thanks in advance.
If you're using APIM with IS as KM, you need to share AM_DB as well. The script is inside dbscripts/apimgt/. That script includes both Identity and Consent scripts. So you can ignore Identity and Consent scripts.

I'm trying to solve my problem when I send class Product (including a binary[] Picture). If I send a Product containing a picture of around 14KB it works, but if I increase the size to 17KB I get the error message:
"The remote server returned an unexpected response: (400) Bad Request.
Because it works with smaller pictures I think it is something wrong with my configurations.
Client (winform) app.config:
http://www.copypastecode.com/157335/
Server web.config:
http://www.copypastecode.com/157339/
I've tried to increased every value (maxBufferSize, maxReceivedMessageSize..) to MAX without any progress?
If you are sending array you should check
maxArrayLength
setting as you most probably hit this limit. What is the length of your array when with 17kb file?
But in general, the best way to upload \ download files are stream upload \ download endpoints
You might consider adding the DataContractSerializer element in your serviceBehaviour element to define the maxItemsInObjectGraph as shown below
<serviceBehaviors>
<behavior name="">
<dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>
</serviceBehaviors>
Also try to add Tracing on your service and see the trace log for the exact reason on why the request is failing.
If your total request length is exceeding 4MB then make sure you have the below:
<system.web>
<httpRuntime maxRequestLength="2147483647"/>
</system.web>
I want to hide the tool I used to create an .exe file. I am not doing anything illegal, I just want to protect my intellectual property from being copied. If I open the exe file in a text editor I see the following section.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
version="XXX.XX"
processorArchitecture="X86"
name="Microsoft.Windows.NameOfTheTool"
type="win32"
/>
</assembly>
I have attempted to change the name to:
name="Microsoft.Windows.SomeOtherName"
This resulted in the following message when I attempted to execute the file.
"This application has failed to start because its side-by-side configuration is incorrect."
How can I solve this?
I've never changed the manifest data, but it might be possible. You should check the linker options.
Regardless, an exe packer like .NETZ may obfuscate things sufficiently.
Now that I look again: the name attribute should be the name of your assembly, not the program (such as VisualStudio) used to create it. If it's not, you'll have to tell us more for us to figure out why. If your program is really script that's fed into some other program, all bets are off.
I have configured log4Net EventLogAppender for Asp.Net 2.0. However it does not log anything. I have following in my Web.Config.
<log4net>
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
<param name="LogName" value="Test Log" />
<param name="ApplicationName" value="Test-Web" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<root>
<priority value="ERROR"/>
<appender-ref ref="EventLogAppender"/>
</root>
<logger name="NHibernate">
<level value="ERROR" />
<appender-ref ref="EventLogAppender" />
</logger>
</log4net>
I already have Test-Log Event Log created and AspNet user has permission on the Event Log registry entry. I also have log4Net configured in Global.asax Application_Start.
log4net.Config.XmlConfigurator.Configure();
Update : I switched on the log4net internal debugging and found the following error in the trace.
log4net:ERROR XmlHierarchyConfigurator: Could not create Appender [EventLogAppender] of type [log4net.Appender.EventLogAppender]. Reported error follows.
System.Security.SecurityException: The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security.
at System.Diagnostics.EventLog.FindSourceRegistration(String source, String machineName, Boolean readOnly)
at System.Diagnostics.EventLog.SourceExists(String source, String machineName)
at System.Diagnostics.EventLog.SourceExists(String source)
at log4net.Appender.EventLogAppender.ActivateOptions()
at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.ParseAppender(XmlElement appenderElement)
Update 2 : It finally works if I create the Event Source (Test-Web) using a console based application in c# and then using the Web Application.
There's some very simple steps to get Log4Net working with the event log with ASP.NET.
Your options are:
Change the app pool
Run the application pool as LocalSystem
Or...set an application name, add a registry key
Configure your config file first so there is an application name.
This is important if you are having a permissions issue, because if you peer at the source you'll see the EventLogAppender defaults the application name (the source column in the event log) to:
System.Threading.Thread.GetDomain().FriendlyName
This requires your application to create a registry key each time the name changes, and is a bit messy. So the best solution is to set your application name. Here's an example EventLogAppender section that sends every error level, the ApplicationName line is the important part:
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
<param name="ApplicationName" value="MY-AWESOME-APP" />
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="INFO" />
</evaluator>
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="INFO"/>
<param name="LevelMax" value="FATAL"/>
</filter>
<layout type="log4net.Layout.PatternLayout">
<!-- The event log already logs the date so just log the message -->
<conversionPattern value="%message" />
</layout>
</appender>
Before making this change, do the following:
Create a registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Application\MY-AWESOME-APP
Create a string value inside this
Name it EventMessageFile, set its value to
C:\Windows\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll
That path appears to work in both 64 bit and 32 bit environments.
With this technique you don't need to set permissions in the registry, and once the key above is created it should just work.
I can't tell you exactly what might be wrong, but if you go here you will see "How do I enable log4net internal debugging?" way down at the bottom. Log4net will not throw exceptions if something is wrong, so you must enable internal debugging in order to get information from log4net.
http://logging.apache.org/log4net/release/faq.html
Edit: Also see the quesiton directly after that one that explains potential hangups with using the EventLogAppender.
I would suspect code access security is preventing you from accessing the event log. This article have information on the topic. Basically, if your ASP.Net application is running under medium trust the app will not have access to event logs.
Note: this is not a restriction built into log4net per se, it is a "feature" of the .Net Framework and ASP.Net.
