Changing Tomcat 5.5's log file

Hello,
I'm using the ServletContext.log method for logging (not log4j I know I know!) but since upgrading to Tomcat 5.5 it sends all the log messages to $CATALINA_HOME/logs/catalina.out
I would like to change this to a different file for each day. How can I do this?
I don't want to change to log4j or java.util.logging as there are lots of ServletContext.log statements throughout my code and don't want the hassle of changing/passing Logger objects around and the like.
Thanks a lot for any suggestions!
Adam

Thanks for your help.
I've explored both suggestions with little luck:
I got the logging info for tomcat 5.5 from http://jakarta.apache.org/tomcat/tomcat-5.5-doc/logging.htmlI followed its instructions and created a logging.properties file in my WEB-INF/classes directory. However, my web app seems to completely ignore it. This is my logging.properties:handlers = org.apache.juli.FileHandler
# Handler specific properties.
# Describes specific configuration info for Handlers.
org.apache.juli.FileHandler.level = FINE
org.apache.juli.FileHandler.directory = /usr/local/jakarta/jakarta-tomcat-5.5.7/logs
org.apache.juli.FileHandler.prefix = servlet-examples.
org.apache.juli.FileHandler.formatter = java.util.logging.SimpleFormatterIn my test servlet, I do the following:
out.println("FileHandler directory: " + System.getProperty("org.apache.juli.FileHandler.directory"));This outputs this:
FileHandler directory: nullWhy is it not using the FileHandler I specified?
Secondly, I renamed catalina.out as you suggested but tomcat will only create a new one after a restart, so this is impractical.

Changing the Naming convention of Log Files

Hi,
Is there a way to change the naming convention of log files. Instead of
00000000.jdb, 00000001.jdb, ... to
DB000000.jdb, DB000001.jdb etc
Thanks in advance.

No, there isn't a way to do that. We didn't anticipate a need to do that -- could you please explain the need?
Putting a prefix on the file name would unnecessarily limit the total size of the data set, if file names are limited to the 8.dot.3 format as you've shown.

Change block size for several log-files simultaneously?

Hi,
I'm using SignalExpress to record and analyze data.
Sometimes I want to analyze the recorded data both for a short period of time and for longer time.
(Imagine creating an average of every second first and then an average of every 10 seconds)
Then I need to change all the log-files, and also the specific parts of the log-file. See attachment.
I have sometimes up to 1000 log-files containing signals from 4 different modules, that makes 4000 adjustments to change from block size 10000 to block size 1000.
Is there any way to adjust all the log-files block size at once?
Many thanks!

Change in Oracle Parameters and Log file size

Hello All,
We have scheduled DB Check job and the log file showed few errors and warnings in the oracle parameter that needs to be corrected. We have also gone through the SAP Note #830576 Oracle Parameter Configuration to change these parameters accordingly. However we need few clarifications on the same.
1.Can we change these parameters directly in init<SID>.ora file or only in SP file. If yes can we edit the same and change it or do we need to change it using BR tools.
2.We have tried to change few parameters using DB26 tcode. But it prompts for maintaining the connection variables in DBCO tcode. We try to make change only in default database but it prompts for connection variables.
Also we get check point error. As per note 309526 can we create the new log file with 100MB size and drop the existing one. Or are there any other considerations that we need to follow for the size of log file and creating new log file. Kindly advise on this. Our Environment is as follows.
OS: Windows 2003 Server
DB: Oracle 10g
regards,
Madhu

Hi,
Madhu, We can change oracle parameters at both the levels that is init<SID> as well as SPFILE level.
1. If you do the changes at init<SID> level then you have to generate the SPFILE again and then database has to be restarted for the parameters to take effect.
If you make the changes in SPFILE then the parameters will take effect depending on the parameter type whether it is dynamic or static. You also need to generate the PFILE i.e init<SID>.ora
2. If possible do not change the oracle parameters using the tcode. I would say it would be better if you do it via the database and it would be much easier.
3. Well its always good to have a larger redo log size. But only one thing to keep in mind is that once you change the size of the redolog the size of the archive log also changes although the number of files will decrease.
Apart from that there wont be any issues.

Hello Experts,
I´d like to change (decrase) the size of the sharedservices_security.log.
There are always 5 files sharedservices_security.log + sharedservices_security.log.2 - sharedservices_security.log.5 (size of one file is 51,201 kb).
How can I change the sharedservices_security.log size?
We have EPM 11.1.1.3 (Essbase / HFM / Planning) on WINServer2003.
Thanks a lot

Log file initial size is not changing

Hi Team,
I have a database on SQL Server 2008 whos log file is 187 GB while total backup size of database is 5 MB.
When I am taking log backup and full backup and trying to change the initial size of log file then it is again reaching to 187 GB strange?
Kindly help
Thanks

If you don't need log backup (no point-in-time restore, no log-shipping, etc.), put the database into the SIMPLE recovery model.

Why did the permissions change on my log files?

My Messaging Server was running just fine, but then it crashed with an error
message that it couldn't write the log files. What happened?

Under the INSTALLATION root, there is only one file that should be owned by
root:

./bin/msg/store/bin/ressh

ALL other files should be owned by the user that Messaging is to be run as.
Changing the ownership of the log files will enable the server to start
immediately, but the ownership of the files should be addressed.

Edited by: user10243788 on Apr 25, 2010 6:12 AMPointing the archive log dest (and/or the FRA) to a new location, or enlarging them, will do no good if you are not performing regular housekeeping on the archivelogs. You will just keep knocking down the same problem over and over.
If you simply delete the archivelogs at the OS level, the database will never know about it and it will continue to think the destination is full, based on records kept in the control file.
For regular housekeeping, you need to be doing something similar to this in rman:
run {
backup archivelog all not backed up 1 times tag='bkup_vlnxora1_arch';
delete noprompt archivelog all backed up 1 times to device type disk;
run {
delete noprompt obsolete;
crosscheck archivelog all;
delete noprompt expired archivelog all;

Moving the online redo log files to different location

We just installed few more drives into our sandbox system and I want to move the online redo log files for better performance. We've got the SAPARCH directory moved to a different location.
Does anyone know how/where I can change the parameters so redo log files are pointed at different drives? It's not in the init<SID>.ora file...

Sumit

Redo log files in case of NOARCHIVELOG Mode.

Question is related with the oracle architure..
database requires a minimum of two redo log files to guarantee that one is always available for writing while the other is being archived, this sounds perfect when DB is running in ARCHIVELOG mode but at the same time it also forces database to have 2 redo log files even when the DB is running in NOARCHIVELOG mode?
Any particular reason..
I would look for reasons not answers on what redo log is and what information it holds etc..

pgoel wrote:
If you had only one file all further changes would have to stop until all changed data blocks had been written to disc. By insisting on a minimum of two log files Oracle can allow the log writer to fill the second log file as the database writer writes out the dirty blocks covered by changes desrcibed in the first log file.What about having a big size redo log file instead of two? Checkppoint being initiated when the redo log file is half filled
I mean, understand the logic, two is better, even best.. but still not getting convinced. I am just trying to think, can not Oracle work with 1 group with 1 big file..specailly when Noarch mode ? Having
Edited by: pgoel on Mar 12, 2011 7:27 PMNo, you still didn't understand and I am not sure how else we can say it. Okay, think about log groups as two buckets which are used to fill the redo content. The LGWR is filling one bucket at a time till it can't accept any more content. Once filled, rather than spilling the content out, it jumps over to the second bucket. Now, taking your statement of big sized redo, Pgoel, it doesn't matter how big sized bucket you bring in, eventually it will fill in. Its not possible that you wont be able to fill it , it just would take more longer than the normal timings. Thats all. So in any case , you need the second bucket. And I am not sure that why you are struck on the archivelog mode. I hope you do understand that its an optional mode. This means, this may or may not be there. If there, its a good thing that before doing the flush of the redo content, Oracle would be able to save the contents in the archived (think about the name, it's very meaning is to preserve, to archive) log file. If not, the redo content wuold be lost and there won't be any record of transactions leaving you to reenter the lost transactions. Its a meaningless point on which you are struck i.e. the archive or no-archivelog mode. Be it whatever, Oracle would still need minimum of the two log groups.

Need to understand when redo log files content is wrote to datafiles

Hi all
I have a question about the time when redo log files are wrote to the datafiles
supposing that the database is in NOARCHIVELOG mode, and all redo log files are filled, the official oracle database documentation says that: *a filled redo log file is available
after the changes recorded in it have been written to the datafiles* witch mean that we just need to have all the redo log files filled to "*commit*" changes to the database
Thanks for help

The wording is poor and should be modified to something like:
<blockquote>
+"a filled online redo log file is available for re-use after all the data blocks that have been changed by change vectors recorded in the log file have been written to the data files"+
</blockquote>
Remember if a data block that is NOT an undo block has been changed by a transaction, then an UNDO block has been changed at the same time, and both change vectors will be in the redo log file. The redo log file cannot, therefore, be re-used until the data block and the associated UNDO block have been written to disc. The change to the data block can thus be rolled back (uncommitted changes can be written to data files) because the UNDO is also available on disc if needed.
If you find the manuals too fragmented to follow you may find that my book, Oracle Core, offers a narrative description that is easier to comprehend.

How open and see Log File in Active Directory

Hello Friends.. ^-^
how i can open log files active directory and see this data files ?
Can export this logs ?
thanks for help.

And adds a definition of edbxxxxx.log for completeness:
These are auxiliary transaction logs used to store changes if the main Edb.log file
gets full before it can be flushed toNtds.dit.
The xxxxx stands for a sequential number in hex. When the Edb.log file
fills up, an Edbtemp.log file
is opened. The original Edb.log file
is renamed to Edb00001.log, and Edbtemp.log is
renamed to Edb.log file,
and the process starts over again. Excess log files are deleted after they have been committed. You may see more than one Edbxxxxx.log file
if a busy domain controller has many updates pending.
