Who uses Application Logs?

Hey there, I just wanted to understand more about the usage of application logs. Do any of you use it for debugging/analysis purposes of your applications? For those that use it, would you mind explain how you use it etc.
Sorry, I'm pretty much an ABAP newbie.

I used Application Logs to get errors or other messages for RFC Calls etc in most of my Custom BAPIs.
See this\
http://help.sap.com/saphelp_nw04/helpdata/en/3a/c8263712c79958e10000009b38f936/content.htm
It doesnt help you much but definetly gives you some idea.
There are a bunch of function modules to help in getting Application Logs. Theoritically an Application Log is similar to System Log. But System Log is for the whole SAP system where are an Application log is specific to the Custom Object (and sometimes even sub-object) that you create and assign to.
Pros: If improves performance by reducing number of database hits and writing the logs locally.
Cons: A lot of effort is needed for initial setup.
If this helps, award points suitably.

Disabling app_dfefault_island folder when using application log

Hello. Is there a way to OC4J use the exactly log path setted in orion-application.xml ? I mean, I edited orion-application.xml to something like
<log>
<file path="file:///c:/apps/myApp.log" />
</log>
but when I start server, I have my log saved in C:/apps/MyOC4JInstance_default_island_1/myApp.log instead of C:/apps/myApp.log.

For XI r2, try turning off DEP. It could have something to do with XI r2 runtime not being compiled with the /NX switch
Try running the app pool in u201CClassicu201D mode rather than u201CIntegratedu201D mode for CR XI r2 or CR 2008.
If it is permissions, try running processmon to see where the access issue is occurring. ProcMon can be downloaded from here:

Application Logging questions, SLG0

Hello all,
I have a couple of generic questions I would like to ask the users of this forum.
1. The people that are using application logging, in what types of situations do you use this functionality, interface programming, updating custom tables, etc.?
2. People that are aware of this functionality and are not using it, why are you not using it?
SAP help documentation has pretty good information about the different function modules that are part of this product.
Thanks
Bruce

Hi Bruce;
As part of the SAP's AII (Auto-ID) production, we use SLG1 extensively because that is where all of the application errors are stored by the system when it processes inbound or outbound messages.
The biggest pro is that it consolidates all of the logging information; the biggest con is that it is hard to search through all that information for a particular message, unless the document number is part of the message. It can be a challenge to find a particular log entry when there can be upwards of 2,500 in one day.
Cheers,
John

Application Logging in ABAP

Hello,
     we are trying to use application logging feature provided with ABAP by way of function modules BAL_LOG_ADD/SAVE etc. the results of these are visible in trasnaction SLG1.
    In our scenario, we want to keep track of different abnormal situations which a background Job of a user with dialogue operation faces. So these situations could be part of a successful or un-successful transactions i.e. there could be and overall COMMIT or ROLLBACK for each transactions for which the log operations have been carried out.
    Now the problem is that , the Logs are not getting saved for unsuccessful transactions i.e. where there is no COMMIT.
     I need your help to get over this situation so that I able to save the Logs (in standard Log objects which are visiible in SLG1) even if the business transaction is not committed.

How can I know which applications were opened by someone else who used my computer?

I'd like to know how to interpret the logs that I get in Console to figure out which applications and which files were opened by someone who used my computer. Thanks for any help you might be able to offer!

If you go to Settings > General > About > Diagnostics & Usage > Diagnositic & Usage Data you can see what was used if it returns an error of any kind.

WDA - Contrast Using Message Manager & Application Logs

Hi there, I'm trying to figure out when it is appropriate to use each. Thus far, it seems that the conclusion that I am coming upon is that the message manager is used for issuing messages at an application user, whereas the application logs should be used to address issues meant for an administrator of the application - basically someone who may be more technical. How is this assumption? Can someone provide me with more inside. I'd love to understand some real life usages. I've read documentation after documentation, but in short, it would be great to leverage off of some who have actually used this in practice.
Thanks in advance.

As I can see from my point of view the main area of using IWDMessageManager is to indicate to user what is wrong with data he or she is trying to change over UI. For example, to show message "The field XXX must not be empty" or to make another kind of validation of input data on UI level.
The main purpose of logging is to trace possible Java exceptions, to trace debugging information (with severity DEBUG), to log some critical errors for technical staff or administrators. The information from the logs can be unhelpful for end-user.

Any guidelines using RSAL_LOG_WRITE to post message in the application log

Hi SDN!
I've programmed a rather complex extractor. As most you will know, the real test is when the extractor goes live in productions;-) So in order to be able to check if everything works as designed - I've customized the extractor in order to post more or less entries in the application logs - This setting can be alterered in the uses system directly.
I've tested the functionality using RSA3 and the application log is filled as expected. The Application log object is RSFH and everything shows up fine. When tring to use it from BW - The application log gets no entries under object RSAP (Where they normally will end up).
I'm using the function module RSAL_LOG_WRITE to add entries to the same log as the macroes LOG_WRITE uses.
Does anybody have any experiance adding entries to the standard application log in the source system when extracting data into BW?

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.

By what time zone does Verizon use to log data usage? When I checked my current usage, there is data used logged in at early morning times and I don't have anyone else who is up at these times.

By what time zone does Verizon use to log data usage? When I checked my current usage, there is data used logged in at early morning times and I don't have anyone else who is up at these times. I also have 1.8+ GB charged to my allowance that I don't understand at all how it is mine because the highest I've ever logged at any given time has been barely 0.5 GB. I'm cruising along at .04-.07 GB and all of a sudden appears a 1.8+ GB deduction/usage and it makes me wonder what the ???? is going on. Is Verizon posting fraudulent usage amounts just to drive up my usage so I have to buy more Gigs?

The time is not the time of actual use, but the time a tower reports the use. The data would have been used anytime prior to that time. Usually, but no always, the usage happened between the time prior and the time reported.
For example:
9:00 AM   1.23 MB
7:05 AM   0.01 MB
1:15 AM 350.03 MB
8:00 PM   23.89 MB
This does not indicate 350 MB was used at 1:15 AM. It really tell you 350 MB was used sometime between 8:00 PM and 1:15 AM.
The times are local time zone as far as I can tell.

Dynadock U10 whith applications who use GDI+

Hi,
I work for a publisher of software who use Gdi+ for graphism on windows forms.
I have a client who have problem with my application and Dynadock U10.
The application works great on his screen 's laptop, but when he put the application on the screen behind the dynadock, all the parts of the screen which are displaying with GDI+ aren't display well : He must pass the mouse over for seing them !
My client has a Windows XP laptop and the driver for dynadock is up to date.
What can I do with dynadock U10 for my application works ?
Bests regards

> What can I do with dynadock U10 for my application works ?
Dynadock U10 use the graphic chip from displaylink
You should ensure that the client has installed the latest driver from this page:
