Output log to application log in application server

Hi Guys,
I am pretty new on J2EE, I created a web application and deployed it on to the oracle application server. I found out that I can view the log file(application.log) for that particular web application on the application control page. What I want to achieve is outputing some custom log on to the same built-in log file. Could anyone please show me how to do that?
Thanks advance
James

Hi, I figured out that ADF is a oracle's implementation of JSF, I tried above approach it did log to a log.xml in the particular folder. However, I would like to output to a log file that you can actually view in the Enterprise Manager Console...
Into the log below:
Log Text
08/04/16 10:13:33.431 10.1.3.3.0 Started
08/04/16 10:13:36.486 webapp: 10.1.3.3.0 Started
(End of Log File) = entries updated since last refresh
Is it possible?
Cheers!
James

View weblogic server logs and application logs

Hi All,
Is there any way to view log files of Weblogic Admin Server, managed server and application logs through OEM console. ( In text editor-- full file / tail -f output)..
Thanks | Kranthi

Thanks Rob.
Even from Weblogic Admin console we cannot view complete log file only some components are shown.
Just thinking will it be a good idea to execute shell script to view log file from Target-Execute Host Command.

How to get the print logs to appear in the application logs folder of windows server 2008 r2

Dear All,
I am a SIEM professional at an IT firm. i am facing a problem. My SIEM solution has an agent for windows. this agent reads only logs from the application, security and system folder of windows event viewer. In server 2008 r2 the printer logs are clustered
in and application and services/microsoft/windows/print services folder. The requirement of my management is that the siem solution should also be able to montior compliance of print policies. that can only be done once the the print logs are viewable in any
of the three event vieweer folders i.e application, system.security. how can i configure windows to make its print logs visible in any of these three folders ?

this may be helpful...

What are F. M's used for creating application log in application server

Hello
plz suggest which F.M's i have to use to create application log
Regards
Kanth

Hi Kanth,
You can go through the following Function Modules :
Application Log Maintenance
(i)APPL_LOG_DELETE With this function module you delete logs in the database according to specified selection conditions
(ii)APPL_LOG_DISPLAY With this function module you can analyze logs in the database.
(iii)APPL_LOG_DISPLAY_INTERN With this function module you can analyze logs in local memory, e.g. when you have only collected log records at runtime and do not want to write to the database.
(iv)APPL_LOG_INIT This function module checks whether the specified object or sub-object exists and deletes all existing associated data in local memory.
(v)APPL_LOG_READ_DB With this function module you read the log data in the database for an object or sub-object according to specified selection conditions.
(vi)APPL_LOG_READ_INTERN With this function module you read all log data whose log class has at least the specified value, from local memory, for the specified object or sub-object.
(vii)APPL_LOG_SET_OBJECT With this function module, you create a new object or sub-object for writing in local memory. With a flag you can control whether the
(viii)APPL_LOG_WRITE_u2026 messages are written in local memory or are output on the screen.
(ix)APPL_LOG_WRITE_DB With this function module you write all data for the specified object or sub-object in local memory to the database. If the log for the object or sub-object in question is new, the log number is returned to the calling program.
(x)APPL_LOG_WRITE_HEADER With this function module, you write the log header data in local memory.
(xi)APPL_LOG_WRITE_LOG_PARAMETERS With this function module, you write the name of the log parameters and the associated values for the specified object or sub-object in local memory. If this function module is called repeatedly for the same object or sub-object, the existing parameters are updated accordingly. If you do not specify an object or sub-object with the call, the most recently used is assumed.
(xii)APPL_LOG_WRITE_MESSAGE_PARAMS With this function module you write a single message, with parameters, in local memory. Otherwise the function module works like
(xiv)APPL_LOG_WRITE_SINGLE_MESSAGE.
(xv)APPL_LOG_WRITE_MESSAGES With this function module you write one or more messages, without parameters, in local memory.
(xvi)APPL_LOG_WRITE_SINGLE_MESSAGE With this function module you write a single message, without parameters, in local memory. If no header entry has yet been written for the object or sub-object, it is created. If you do not specify an object or sub-object with the call, the most recently used is assumed.

Swapna.

Difference between Application log and Application server

Application log is details about the business transaction, ie status / error messages
Application server is the system <hardware> on which application is running.

EM Application Log and Web Access Log growing too large on Redwood Server

Hi,
We have a storage space issue on our Redwood SAP CPS Orcale servers and have found that the two log files above are the main culprits for this. These files are continually updated and I need to know what these are and if they can be purged or reduced down in size.
They have been in existence since the system has been installed and I have tried to access them but they are too large. I have also tried taking the cluster group offline to see if the file stops being updated but the file continues to be updated.
Please could anyone shed any light on this and what can be done to resolve it?
Thanks in advance for any help.
Jason

Hi David,
The file names are:
em-application.log and web access.log
The File path is:
D:\oracle\product\10.2.0\db_1\oc4j\j2ee\OC4J_DBConsole_brsapprdbmp01.britvic.BSDDRINKS.NET_SAPCPSPR\log
Redwood/CPS version is 6.0.2.7
Thanks for your help.
Kind Regards,
Jason

Configure Log File for each web application deployed in weblogic server usi

Hi All,
How do I configure Log4J to log separately for each web application? i.e. Assuming, I have a web application "AWeb" and a web application "BWeb". I need a log file to be created for AWeb Separately and BWeb Separately. i.e. All the log information for "AWeb" web application will be stored in AWeb.log and all the "BWeb" web application will be stored in BWeb.log
Do you have any sample code and configuration details for the above-mentioned requirement?
Thanks in Advance,
C R Baradwaj

You do not need to do anything strange, just use log4j the usual way with the exception that you do not need to init log4j (this is not necesary when using a log4j.xml.)
A minimal sample of a log4j.xml is
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.SimpleLayout"/>
</appender>
<root>
<priority value ="debug" />
<appender-ref ref="ConsoleAppender"/>
</root>
</log4j:configuration>
You just have to be sure that you have different log4j.xml in your classpath for different web applications.

LG

Can anyone share with me his experience about ld.so.1?? What is it and why does it cause my apps server to reboot?

It looks like you might simply have run out of memory. It just looks like the JRE tried to adjust its memory map and run out space. When mprotect fails the problem probably isn't with the .so itself.
What are the memory characteristics of your machine? Including the heap and stack space that you allocate for your JVM, as well as the actual physical and swap space available on the server.

os the log of the "parent application". This is rather high level in the container. The message in the logfiles tells you that a procedure doesn't exist.
This can mean 3 things:
1. The procedure really doesn't exist
2. The procedure expects different parameters then passed
3. In the procedure a specific array member is called (but not found). (don't know how to explain this better in English, sorry for that).
It has been a while since I touched portal. In the past portal used a DAD (located in your HTTP-Server configuration). By changing the error style of the dad, you might find a more comprohensive error message.

Log messages for 'auditing' are different in 'general' and'application log

Hi,
From UI, When I audit a file using a profile which comprises of user-defined 'rules/categories/analyzers', I will get log messages at ''File-name(Application) log window' and 'Messages' log window, which are located at bottom of Jdev UI page. One common message in both the log windows is
" <n1> violations, <n2> exceptions, <n3> documents, <n4> seconds>.
But here the 'n1,n2,...' numbers are dfferent in two windows though the log output is for a same file. In this the 'file-name' log shows the correct
Example:-
In 'file-name' log window ,it shows as:
3 documents, 8 violations, no exceptions
In messages window, it shows as
"Audit starting on EFC.jpr (Default)
Audit completed: no violations, no exceptions, 3 documents, 1 second"
If I use the 'pre-existed'(Jdev's) rules profile, I will get similar output in both log windows.
From this I concluded that there is something missing to register for a new 'rule/category/analyzer'.
Could you suggest me in this case. Do I forgot anything to do in any files of '<rule-implementation.java>', 'audit.properties', <add-in launcher>.java, extension.xml.
Actually, I want to use 'ojaudit' executable from command line to my project files. Here I observed that the output of the 'ojaudit' is similar to the above explained 'Message' log window in JDeveloper UI. But where the 'Message' log window output is not correct for user-defined rules.
Regards
Madhu

Romano,
In the upcoming production release (planned to be released next week), we added caching of authorized roles and permissions in JhsAuthorizationProxy class.
I suggest you wait for this relase, if the problem persists, it is most likely an ADF issue (as is the logging)

Exporting and Importing Data of Application Log

Hello,
We do migrate an application from SAP System A to SAP System B.
Despite the application logic, we do need to migrate some data, too.
For this we do write an export report in System A that writes the data of some tables to files on the app server..
Another report in system B takes the files and fills the respecting tables.
So far so good:
One table (which reports certain actions) contains the handle to the application log, which was created for this action.
I do want to extract this application log and later import this log in the other system, but do not know how this can be done in the best way.
Do you have any suggestion ?
Best regards
Michael

In my experience, it's an unrealistic expectation.
SAP doesn't provide a straight path to migrate logs the way you plan to do. It's kept in a combination of tables and index files on the system. So even if you were to successfully extract it, when you load the data into system B you will lose the date and time stamp. When you create a log entry, it picks up system date and time. That's what an auditor would look for.
An alternate solution would be to read the application log and store it in a new custom table in system B.
Any reporting should be done off that as of a specific date.

How to know the number of Active users logged in to a Essbase Application?

Hi,
Is there way to capture/log the number of active users who have logged into a particular Essbase application at a given time.
In Essbase or in Shared services?
I know we can see the EAS-Edit Sessions shows the actively logged-in users, then we can sort on the application/database & manually count the number.
Is there a way to capture it in a log at a given time on a regular basis. Any MAXL or Shared services feature?
Appreciate your thoughts.
Thanks,
Ethan.

You could use maxl .
display user all;
there will be a column called "logged in" which will display true/false for the users
but that will just show if they are logged into the server and not the application
You can also use use display session
display session all;
or
display session on application sample;
which should show what you are after.
Cheers

How come this message is coming in the application log, since no one has tried to log in to the application?

Hi Both are 2008R2 version. My doubt is I can see that login failed message in application log but how to find out which process is trying to use that login?
First observe that this is something that runs on the same machine as SQL Server. (The error message says "CLIENT: <local machine>".) That may be a clue enough.
If not, set up a includes Audit: Login Failed and no other event. Of interest are the columns ApplicationNmae and the the column ClientProcessID. ApplicationName may be sufficient, but if not you can use ClientProcessID and match this against the PIDs you
see in Task Manager or Process Explorer. There is a risk it is a short-lived process and then you will have to look at Process Explorer and Profiler in parallel.
