Log file creation ( Trace)

Hi,
I am trying to do the global trace for the application and
set the following in the mm.cfg file
ErrorReportingEnable = 1
TraceOutputFileEnable =1
MaxWarnings = 100
TraceOutputFileName = "C:\Documents and
Settings\user\myProject.log"
The file is not created when I am using a trace("Test") in
the button click event on the page.
Is there anything important that I am missing?
Thanks in advance.

Hi,
Post your question in the appropriate General Database Discussions.
Thanks,
Hussein

Question regarding alert log file and trace files

What should be the alert log file size ? And when should it be deleted? And for how many days user trace files should be kept?
Also will anyone please tell me the importance of these files.
Thanks

Log File Creation Confusion

SQL*Plus: Release 10.2.0.3.0 - Production on Mon Mar 11 11:42:45 2013
Copyright (c) 1982, 2006, Oracle. All Rights Reserved.There are some initialization parameters that decide the location of the online redo log files in general.These initialization parameters are
- DB_CREATE_ONLINE_LOG_DEST_n
- DB_RECOVERY_FILE_DEST
- DB_CREATE_FILE_DEST
I could not understand the level of precedence of these parameters if you set each of them for creating online logfile, if i set all these parameter then creating online log file always goes to the path which define in parameter DB_CREATE_ONLINE_LOG_DEST_n and ignores the others parameter (DB_RECOVERY_FILE_DEST,DB_CREATE_FILE_DEST).
If i just set the last two parameter (DB_RECOVERY_FILE_DEST,DB_CREATE_FILE_DEST) and do not set the DB_CREATE_ONLINE_LOG_DEST_n the logfile created in both location DB_RECOVERY_FILE_DEST,DB_CREATE_FILE_DEST) with mirrored mechanisim.

'DB_CREATE_ONLINE_LOG_DEST_n'?

DB_CREATE_FILE_DEST is used if DB_CREATE_ONLINE_LOG_DEST_n is not defined.
DB_RECOVERY_FILE_DEST is used for multiplexed log files.
Thus, if Oracle uses DB_CREATE_FILE_DEST (because DB_CREATE_ONLINE_LOG_DEST_n is not defined), it multiplexes the log file to DB_RECOVERY_FILE_DEST if DB_RECOVERY_FILE_DEST is also defined.
If, however, DB_CREATE_ONLINE_LOG_DEST_1 is used, Oracle expects you to define DB_CREATE_ONLINE_LOG_DEST_2 as well for multiplexing the log file; else it assumes that you do not want the log file multiplexed. The fact that the parameter ends with an n means that Oracle uses the n=2 f or the multiplexed location if defined.

Sqlnet.log file creation permissions

One of my sites has a sqlnet.log file that has been symlinked to /dev/null and we are trying to determine if this has caused the issue with /dev/null's permissions being reset to 660 instead of 666.
It looks like the other sqlnet.log files that are not symlinked to /dev/null are 640 so we are not sure this is the issue.
Does anyone know if oracle changes permissions on the sqlnet.log file at creation or access time? And how it might change those permissions?
This is on Oracle 10g running on RHEL4
edit: I typed sqlnet.ora instead of sqlnet.log ... oops.
Edited by: user12198769 on Nov 10, 2009 7:35 AM

looks to be just the default in that file:
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
There are several sqlnet.log files in other places on the server yet there is only one oracle home on here so is there another location that has sqlnet.ora info?

Disable Log file creation for a Berkeley DB database

Hi,
I'm using Berkeley DB 6 with Oracle Mobile Server 11.3. When I sync a lot of data, a lot of logfile are created and I think that this is really slowing down my sync process. Since I never need to recover those client database, I would like to know if it is possible to disable log creation on a Berkeley Database?
Thank you

The version of BDB that is used for DMS is TDS (Transaction Data Store). In that environment, logging is needed to ensure recoverability. There isnt a way to disable logging. If you never need to do recovery, then you can use the BDB utilities and occasionally do checkpoints which will flush the cache, or you can shut down the client application. After this is done then you can remove the log files, since you are claiming that you will not need them for recovery.
thanks
mike

Exchange Server 2010 - Message Tracking Logs - Log file creation

Hi,
I would like to find out on the behavior of the exchange server in the way that it logs the message tracking.
Currently the parameter used is
MessageTrackingLogMaxDirectorySize - 10GBMessageTrackingLogMaxAge - 30daysI would like to check when the Max Directory Size has exceeded the value indicated, does Exchange server immediately deletes the oldest log file to make space for the new logs?And in the event that the oldest file is being open or locked, will exchange server delete the next oldest file? or it will reattempt to delete the "locked" file for a period of time?Lastly, when these "oldest" files is not able to be deleted, will exchange server stops logging new tracking events?Thanks!

Hi Zack,
Thank you for your question.
If you have configured the parameter of “MessageTrackingLogMaxDirectorySize” and “MessageTrackingLogMaxAge”, we think you have enable circular logging, it will delete the oldest message tracking log files for new log file when the either of the following
conditions is true:
The message tracking log directory reaches its specified maximum size.
A message tracking log file reaches its specified maximum age.
In addition, it didn’t exceeded the value indicated.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

Log file creation -- BDC

Hi friends.This is Sudhir . I have a scenario of loading mass vendor data. If in case any error occurs while loading the error record should be created as log file. Do we have any function module to create the log file?
Hope your answers will be helpful to proceed further.
With regards ,
Sudhir S

Are you looking a way for generating logs as the ones you can see in SLG0?
You can also store them into a spool.
To store them into a file, you can simply read the spool output (or you can maybe use a SUBMIT ... EXPORTING LIST TO MEMORY to avoid the spool).
In that case, please refer to [sap library|http://help.sap.com/saphelp_nw2004s/helpdata/en/d3/1fa03940fab918e10000000a114084/frameset.htm]
and SBAL* demo programs (use of BAL_* function modules)

Re: identifying server log file when runningdistributed

Hi John, I can give you some TOOL code which will get the process
id, but I do have to stray outside of Framework :-). The following
code uses classes from the SystemMonitor project which was
introduced in release 2 of Forte (this code won't work on R1):
partAgent : SystemAgent;
pidInst : ConfigValueInst;
pid : TextData;
partAgent = SystemAgent(task.Part.Agent);
pidInst = ConfigValueInst(partAgent.FindInstrument('ProcessId');
pid = TextData(pidInst.GetData);
The result is that the variable pid contains the process id in string form.
This could be converted to numeric form if needed.
If what you're really after is the partition's log file name, then the following
code will do the trick (it takes into account the differences in how the log
files are named for interpreted vs. compiled partitions):
partAgent : SystemAgent;
logFileInst : ConfigValueInst;
logFileName : TextData;
-- Get our agent and try to get the log file inst
partAgent = SystemAgent(task.Part.Agent);
logFileInst = ConfigValueInst(partAgent.FindInstrument('LogFile');
-- Interpreted partition don't have their own log file, so check
if (logFileInst = NIL) then
pidInst : ConfigValueInst;
pid : TextData;
-- We must be an interpreted partition get our pid
pidInst = ConfigValueInst(partAgent.FindInstrument('ProcessId');
pid = TextData(pidInst.GetData);
-- Build log file name
logFileName = 'forte_ex_';
logFileName.Concat(pid);
else
-- Get the name of the log file from the instrument
logFileName = TextData(logFileInst.GetData);
end;
The available agents and their instruments and commands are documented
in the manual "SystemMonitor Project". I'm at home now, so I don't have
the page numbers. Some additional agents (which were added after this
manual went to press) can be found in Tech Note #10475. Also, econsole
and escript can be handy since any instrument you can see in these tools
can be accessed from TOOL code. Hope this is of some use.

I have not yet seen a way to programmatically obtain the process ID for a

What kinds of strategies are folks employing out there?

Hi John,
I think that Sean Fits answered your question about TOOL code to get the PID
number. I just want to complement on the loging strategy.
There is one log file for every active partition of an application. I think
it is useful in some cases that a distributed application gets a centralized
log file to trace the exact sequential flow of processing among all the
partitions. This is useful during the initial debuging and tuning. In fact
something similar to the UNIX syslog file.
For doing so it is easy to implement a custom central log Mgr in one
partition and to have all partitions use it when needed (it doesn't prevent
to continue using the standard LogMgr in addition). This central LogMgr
automatically adds the date&time plus the node name, partition name, ... to
the log messages it receives.
The flags which apply are those of the partition where the central Log Mgr is.
Because of potential concurency requests from the several partitions
accessing the central Log Mgr, it is not possible to support the "Put" and
PutHex" methods. Only complete lines can be logged (Putline and PutHexLine).
Attached is the TOOL code of my TraceService plan that implements it.
Remark : the "Phr" in the names relate to the name of the application we
have here under development.
To use the central Log Mgr, a partition must create an object of class
PartitionLog, and then log messages must be sent to it the way you send them
to the standard LogMgr; it will manage to send them to the central Log Mgr.

Who writes alert log file?

Hi guys ,
I have been searching for answer to this question,.............
Which process(backgroud process) writes to alert log file?

Trace files for user processes are normally in the user_dump. They are created only when tracing is requested OR when Oracle encounters an error.
The alert.log is a file that is used to continously display the status of the database as it changes with important events (e.g. archival of log, alter system commands, ora-1555 errors, indexes unusable, datafile space allocation etc). Most of these are issues which affect the entire instance/database. However, where a sever error is encountered in a user process, Oracle writes a trace file in user_dump_dest for that error and a message indicating the error and the name of the trace file to the alert.log.
Similarly, the background processes may also be writing to their own trace files to indcate status /tracing.
The level of detail being logged can vary by version and by setting specific database events (if specified by Oracle Support) in the instance.

Jar file: log file is not created!

Hi, I create a log file with these instructions:
//logger
          FileHandler fh = new FileHandler(LOG_FILE,true); //append mode
          fh.setFormatter(new SimpleFormatter());
          logger = Logger.getLogger(this.getClass().getName());
          logger.addHandler(fh);It works well as long I execute it normally, but when I create a .jar file and put this logger class inside logger file is not created..how come?

Hi, I create a log file with these instructions:The code extract creates a Logger object, sure, but does that mean it creates a log file? The log file creation could be deferred until the first usage of the logger...
It works well as long I execute it normally,Let's clarify: do you mean, when executing from your IDE, or when executing via a command line?
but when I create a .jar file and put this logger class inside logger file is not created..how come?Let's clarify: do you mean, when you execute the same code packaged in a jar file?
The most likely issue is configuration: apparently the various ways in which you run your program use different logging configurations.

How can I extract the data from a Real-time Execution Trace ".log" file?

I would like to get the data for the traces from the Real-time Execution Trace toolkit ".log" file to read in Excel and generate a report.

Hi Chuck,
Have you tried reading it into a text or binary file first and then generating a report using the Report Generation VIs?
