I have a server I made in Java that needs to use a database, I chose HSQLDB.
So I have a lot of entries in my server like:
Logger.getLogger(getClass().getName()). severe or info ("Some important information");
When I run my server it goes to System.out which I think its the default configuration of java.util.logging?, so far its ok for me, and later I will make it go to a file ...
But, the problem is, when I start hsqldb it messes up with the default configuration and I can´t read my log entries on System.out anymore..
I already tried to change hsqldb.log_data=false, but it still messes up the default configuration.
Can someone help me??
I dont want to log hsqldb events, just my server ones.
Thanks
This issue was reported and fixed in the latest version 2.2.0 released today.
Basically, you set a system property hsqldb.reconfig_logging to the
string value false.
A system property is normally set with the -D option in the Java startup command for your application:
java -Dhsqldb.reconfig_logging=false ....
See below for details of the change:
http://sourceforge.net/tracker/?func=detail&aid=3195462&group_id=23316&atid=378131
In addition, when you use a fremework logger for your application, you should configure it directly to choose which levels of log to accept and which ones to ignore.
The hsqldb.applog setting does not affect framework logging and only controls the file log.
The hsqldb.log_data=false is for turning off internal data change logging and should not be used for normal databases. Its usage for bulk imports is explained in the Guide.
Try setting hsqldb.applog to 0, that shuts off application logging to the *.app.log file.
Start your server with a property pointing to the location of a dedicated properties file:
-Djava.util.logging.config.file=/location/of/your/hsqldblog.properties"
Which contains the following line to change Java logging for Hsqldb.
# Change hsqldb logging level
org.hsqldb.persist = WARNING
Side note, you can choose from the following levels:
SEVERE WARNING INFO CONFIG FINE FINER FINEST

I'm using Sentry to log errors that occur in my code and every time I launch my application I see that Sentry logs information like
[main] INFO io.sentry.DefaultSentryClientFactory - Using an HTTPS connection to Sentry.
Is it possible to suppress this kind of logs?
I don't know which logging framework you are using but each of them offers a way to change the threshold for a specific package (or class), so you could just disable or raise it for io.sentry.DefaultSentryClientFactory. For example, here's one for log4j: https://stackoverflow.com/a/4973082/11958
PS: I work on sentry-java and I think those shouldn't be at the INFO level, honestly. I'll change that in a future release.
I've already spent more than 2 days trying to make this work without any result. The server is WebLogic 12c with embedded Coherence server. It is important to mention that I do not run Coherence in standalone mode, instead it starts automatically alongside the application server that has access to Coherence via JNDI context. I am trying to implement POF serialization approach using PortableObject interface to serialize certain objects I save in Coherence. I've also created the corresponding pof-config.xml registering the objects I'm planning to serialize. The only problem is: How do I add the override to the coherence class path?
According to http://docs.oracle.com/cd/E24290_01/coh.371/e22837/gs_config.htm#COHDG5014 I can use the following system property:
java -Dtangosol.pof.config=MyPOF.xml -cp COHERENCE_HOME;COHERENCE_HOME\lib\coherence.jar com.tangosol.net.DefaultCacheServer
The only problem here is that I have no idea which sh/cmd file to edit, since all edits I made to the files in Oracle_Home\coherence\bin\ had no effect.
Also the same article says that there is a way to confirm the pof-config override:
The output for a Coherence node indicates the location and name of the POF configuration deployment descriptors that are loaded at startup. The configuration messages are among the messages that display after the Coherence copyright text is emitted and are associated with the cache service that is configured to use POF. The output is especially helpful when developing and testing Coherence applications and solutions.
Loading POF configuration from resource "file:/D:/coherence/my-pof-config.xml"
But I couldn't find any of the mentioned lines in the logs produced by the server instance.
Any ideas?
Instead of editing files inside of your Oracle_Home, try the following inside of the weblogic admin console:
Login to admin console
Servers link -> Server Name
Click the Server Start tab
Edit the Arguments: text box and add in -Dtangosol.pof.config=MyPOF.xml
You can also change the classpath, Class Path: box, here if you need to
Every time your server starts it should have that property. If you are not using the nodemanager to start your server, you should do the following instead. Keep in mind this will change the properties for every server in your weblogic domain:
Navigate to your <domain home>/bin directory
Edit startWebLogic.sh/cmd
Edit the JAVA_OPTIONS= line and add in -Dtangosol.pof.config=MyPOF.xml
You can also change the classpath CLASSPATH= here if you need to
My application is using Spring to handle the interaction with database (Sql Server)
And commons-logging-1.1.1.jar, log4j-1.2.17.jar, slf4j-api-1.6.3.jar and slf4j-log4j12-1.7.6.jar are put into build path for the logging framework of the application.
The last two logging jar (slf4j-api and slf4j-log4j12) are for another component inside the application to use log4j.
Here is my questions:
When Spring-Jdbc runtime excecption happens, the exception is only showed in the console of eclipse with the font color red. The exception is NOT logged into the log file. But the normal log (like log.info(...)) are all in the log file. Why can't the run-time exception be in the log file and how to solve this problem.
When I use SimpleJdbcCall to call the stored procedure with parameters in MapSqlParameterSource, the following log shows up:
14:43:30 [INFO ] Added default SqlReturnUpdateCount parameter named #update-count-1
14:43:30 [INFO ] Added default SqlReturnUpdateCount parameter named #update-count-1
......
It's really annoying because the number of this message is so large. I want to turn off this particular log message without affecting another logging with the same level (INFO)
And my log4j.xml is fine I think because the logging are basically fine except the above issues.
Spring is using commons-logging internally that's why you can see the messages in your eclipse console. To redirect commons-logging to slf4j/log4j you need to remove commons-logging-1.1.1.jar from your classpath and add jcl-over-slf4j.jar from your slf4j version. To get rid of the dublicate red eclipse messages (jul and jcl) you can set the logging level in logging.properties for the console handler to warning:
java.util.logging.ConsoleHandler.level = WARNING
Second issue was solved here.
How can I maximize the log information an embedded neo4j database will give me, so that I can see what's going on?
Recent technical discussion on the google group called for an excerpt of messages.log, but I don't have that log file since I'm running embedded. I have consulted the server configuration docs (http://docs.neo4j.org/chunked/stable/server-configuration.html#_server_logging_configuration) but they don't tell me the actual names of the loggers to use.
I have tried this:
java.util.logging.Logger.getLogger("org.neo4j").setLevel(Level.ALL)
But by default, and also with this line of code, I see no log messages from neo4j at all.
I'm trying to get some of the server message logs to debug why certain read-only transactions are failing and rollback is failing; first I have to figure out how to get neo4j to tell me what's going on in this embedded database.
Actually you have messages.log it is in your graph.db directory.
And there are loads of diagnostic, config, tuning, memory and other information in that file. So very valuable.
I have an application which is configured on IBM WebSphere 6.0 version.
In that application, where ever the System.out.printlN() Statements, are there
Where do they get printed?
I mean which log files, will get it printed?
In standalone I can check in the console, that application is deployed in windows server box
How to Identify where all the log.debug, log.info statements get printed from the application into the server box.
I tried checking in log4j.properties, but didnot find any useful info about that.
Background, we have a Websphere app server, where we have configured 2 Nodes and I am deploying in the Node 01, on my changes and trying to debug, but no help.
Please guide if any one has past exp on it.
I haven't been using WebSphere 6 lately. I newer versions you have a profile directory and a log directory within where the log file reside.
The second option is to go into the WAS administration console and go to "Troubleshooting > Logs and Trace > server_name " there you can directly view the logs. This way is documented for WAS 6.0 as well.
As others have hinted, by default the SystemOut.log and SystemErr.log files are located in each node's profiles/<profileName>/<serverName>/logs directory. (These locations and file names can be overridden in the Administration Console.)
log4j logs will depend on the appenders in your log4j configuration (could be a log4j.properties or a log4j.xml file), but might also be affected by whether anything in your application uses Jakarta Commons Logging. If it does, you may find all log4j logging also going to SystemOut.log.
It should get logged in Program files/IBM/SDP/profiles/runtimes/baseV6...
something like this .currently am at home and I don't have exact path.But search in profile directory .
You should always define your own path for appenders in your applications logging.xml instead of using default path of WAS.
The log files are resided at C:\Program Files\IBM\SDP\runtimes\base_v7\profiles\was70profile1\logs\server1
