Some character adding up starting of log file?

your_shadow03 · 03-02-2010, 07:20 AM

My run.conf says:

Code:

JAVA_OPTS="-server -XX:PermSize=128m -XX:MaxPermSize=256m -XX:-PrintTenuringDistribution -XX:NewSize=256m -XX:MaxNewSize=384m -XX:+UseParallelGC -XX:SurvivorRatio=12 -Xmx1280m -Xms1280m -XX:ThreadStackSize=256 -XX:+DisableExplicitGC -verbose:gc -XX:+PrintGCDetails  -XX:+PrintTenuringDistribution -XX:ParallelGCThreads=2 -Xloggc:/project/gm.log -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true"

Quote:

-Xloggc:file
Report on each garbage collection event, as with -verbose:gc, but log this data to file. In addition to the information -verbose:gc gives, each reported event will be preceeded by the time (in seconds) since the first garbage-collection event.
Always use a local file system for storage of this file to avoid stalling the JVM due to network latency. The file may be truncated in the case of a full file system and logging will continue on the truncated file. This option overrides -verbose:gc if both are given on the command line.

Please check you are using both the options. This probably is not the cause for the binary data in the file. But it is there so I highlighted it.

Secondly, I am still not sure how can you be so sure that these junk character will be there on the first line. For me these are gc logs and can be at any place.

Do you find any exception just above or below these junk character in the log file?

You can try invoking this java command on the command line to see what could be the probable exeception that is dumping these chars in the gc log file.

Hi,

I'm not a java man, but doesn't this: -Xloggc:/project/gm.log mean you are logging the garbage collector? I do believe you need a special viewer to 'see' that data.

A quick search comes up with GCView (freshmeat).

Hope this helps.

Can anyone confirm the same as I am not sure if that could be the reason.
What entry I should make to the file?

your_shadow03,

I've yet again merged two of your threads on the same subject; you've
been warned for double-/ multi-posts so many times it's not even funny.

Next double post of yours I'll give you an out-time of a few weeks.

Cheers,
Tink

Sorry Moderator,

The Two Thread are different but the result will the same.
Thats what made me ask in different respect.
Anyway, I am trying to get help from experts in two different ways.

anyway, will take care for next time.

Guys !!!
What my main aim is to remove this first line with junk character.
I did attempted removing the line through script but couldnt make it happen.
It does disturb the logs provisioning.
But ASAP I copy it temporarily to a file , make changes and copy it back those characters again appear.
Seems that something has to be done with run.sh (==<< Main culprit).

druuna · 03-02-2010, 11:34 AM

Hi,

I've re-read most of the merged thread and see one thing that I cannot place:

You (the OP) mention that the following line is in your run.conf file:

CustomLog "| /usr/sbin/logrotate /mc.com/gm.log 60" common

Should that be there? To my knowledge that entry isn't jboss specific (looks more like apache/tomcat).

Hope this helps.

your_shadow03 · 03-02-2010, 11:53 AM

I dont think it should affect the logs being provisioned as binary format.

druuna · 03-02-2010, 12:02 PM

Hi,

Have you actually tried to remove it.

your_shadow03 · 03-02-2010, 12:15 PM

Well,, I am not in corporate VPN..
Will surely give it try and let you know the status.
You can suggest me the other options too..if thats in your mind.
I have put the same query to Jboss Community too.
Lets see if it could be helpful.

your_shadow03 · 03-03-2010, 07:15 AM

I tried it now..
It's not provisioning this time since that is only entry in run.conf.
Removing it from the file will not provision the logs.

druuna · 03-03-2010, 07:26 AM

Hi,

It is the only entry?? I doubt it. This was provided by you in post #8 as being the content of run.conf:

Quote:

CustomLog "| /usr/sbin/logrotate /mc.com/gm.log 60" common

JAVA_OPTS="-server -XX:PermSize=128m -XX:MaxPermSize=256m -XX:-PrintTenuringDistribution -XX:NewSize=256m -XX:MaxNewSize=384m -XX:+UseParallelGC -XX:SurvivorRatio=12 -Xmx1280m -Xms1280m -XX:ThreadStackSize=256 -XX:+DisableExplicitGC -verbose:gc -XX:+PrintGCDetails -XX:+PrintTenuringDistribution -XX:ParallelGCThreads=2 -Xloggc:/mc.com/gm.log -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true"

- The first entry is not jboss/java specific (as stated before).
- Both entries seem to point to gm.log (the -Xloggc:/mc.com/gm.log in the JAVA_OPTS line).
