Log Files on UNIX

We are trying to debug the Biller Direct application by using either the SAP Logging Framework or standard System.out.println statements. On Windows the logging is written to either C:\usr\sap\AZ1\JC00\j2ee\cluster\server0\log\console_logs\output.log or C:\usr\sap\AZ1\JC00\j2ee\cluster\server0\log\applications\com.sap.fin.ebpp\ebpp.trc.0. On UNIX we do not see anything written to these files. We have verified that the Severity is set to debug and the Log Destination for application_sap.com/com.sap.fin.ebpp_com.sap.fin.destination is ./log/applications/com.sap.fin.ebpp/ebpp.trc.
Does anyone know what the problem is?

Make sure you have the J2EE server set to DEBUG mode in the Config Tool. Also in the Visual Admin, in the Kernel, make sure the LogManager attribute for ForceSingleTraceFile to 'NO'. Restart the server and you should see the ebpp.trc

Redirect DBMS_OUTPUT to calling application and to log file

Hi,
I have a procedure to insert a set of records into a table using Merge statement and capture the inserted record count.
Currently i display the record count using DBMS_OUTPUT in Oracle SQL Developer tool using DBMS_OUTPUT.ENABLE.
How do i redirect this output to both calling application and Log file on Unix server.
I have more DBMS_OUTPUT statements in Exception handling to handle failed inserts. How do i redirect these statements to Calling Application and Log file on Unix.
Can we send any email to a group from PL/SQL if at all program fails and Exception handle is triggered OR if the program complete successfully.
I appreciate your responses.

I appreciate your responses.DBMS_OUTPUT is not the correct tool to be using for outputting information. It writes data to a buffer on the server, and then it's up to the client tool to read the data out of that buffer using the DBMS_OUTPUT.GET_LINE call.
You could try implementing something like that in your own application if you wanted, but in truth, if you're wanting to capture some trace of what's happening in your application then you are better logging those things to a table using an autonomous transaction procedure, and then have whataver application you want just query that table.

How to Monitor oracle Application in unix through log files?

Hello Every Body,
I Would Like To Know The Log Files locations to monitor the start-up and stop error entries in the logs , like web server where its log files located,...forms server ...etc

You can also use Oracle Applcations Manager (OAM), with OAM you can view information on general system activity including the statuses of the database, concurrent managers and other services, concurrent requests, and Oracle Workflow processes. You can also start or stop services, and submit concurrent requests. You can also view configuration information, such as initialization parameters and profile options .. etc.

Scrolling SSL message in PS Unix Process Scheduler PSAESRV log file

This message is being spammed to the AESRV log file and it's doing it's best to fill up the partition. We recently migrated to new hardware, and it looks like the problem started day 1 from there. There are no other known issues at the moment. Any idea what's causing this, how to stop it and/or how to put a muzzle on it?

Where do you upload the root certificates to the DB? I now think this issue may be arising out of some custom encryption that was done a while back and has since progressively gotten worse with higher utilization. Any idea where the root certificate would be found for a custom encryption project?

Steps to empty SAPDB (MaxDB) log file

Hello All,
i am on Redhat Unix Os with NW 7.1 CE and SAPDB as Back end. I am trying to login but my log file is full. Ii want to empty log file but i havn't done any data backup yet. Can anybody guide me how toproceed to handle this problem.
I do have some idea what to do like the steps below
1. take databackup (but i want to skip this step if possible) since this is a QA system and we are not a production company.
2. Take log backup using same methos as data backup but with Log type (am i right or there is somethign else)
3. It will automatically overwrite log after log backups.
or should i use this as an alternative, i found this in note Note 869267 - FAQ: SAP MaxDB LOG area
Can the log area be overwritten cyclically without having to make a log backup?
Yes, the log area can be automatically overwritten without log backups. Use the DBM command
util_execute SET LOG AUTO OVERWRITE ON
to set this status. The behavior of the database corresponds to the DEMO log mode in older versions. With version 7.4.03 and above, this behavior can be set online.
Log backups are not possible after switching on automatic overwrite. Backup history is broken down and flagged by the abbreviation HISTLOST in the backup history (dbm.knl file). The backup history is restarted when you switch off automatic overwrite without log backups using the command
util_execute SET LOG AUTO OVERWRITE OFF
and by creating a complete data backup in the ADMIN or ONLINE status.
Automatic overwrite of the log area without log backups is NOT suitable for production operation. Since no backup history exists for the following changes in the database, you cannot track transactions in the case of recovery.
any reply will be highly appreciated.
Thanks

Hello Mani,
1. Please review the document u201CUsing SAP MaxDB X Server Behind a Firewallu201D at MAXDB library
http://maxdb.sap.com/doc/7_7/44/bbddac91407006e10000000a155369/content.htm
u201CTo enable access to X Server (and thus the database) behind a firewall using a client program such as Database Studio, open the necessary ports in your firewall and restrict access to these ports to only those computers that need to access the database.u201D
Is the database server behind a Firewall? If yes, then the Xserver port need to be open. You could restrict access to this port to the computers of your database administrators, for example.
Is "nq2host" the name of the database server? Could you ping to the server "nq2host" from your machine?
2. And if the database server and your PC in the local area NetWork you could start the x_server on the database server & connect to the database using the DB studio on your PC, as you already told by Lars.
See the document u201CNetwork Communicationu201D at

Alert Email notification for Log file alerts

Hi,
Scenario: SCOM 2012 R2 UR4.
There are created unix/linux log file monitoring objects. In SCOM console I can view alerts related to unix/linux log file monitoring. Email notification is: Warning or Critical for severity, and, Medium or High for priority. The alerts for unix/linux log
file are severity warning and priority medium.
In my inbox there are emails for alerts (Warning or Critical for severity, and, Medium or High for priority) except for unix/linux monitoring.
The question is:
How to enable email notification for unix/linux log file monitoring?
Thanks in advance!

Log.0000000001: log file open failed

I have been seeing an error off and on recently where my app will go along just fine writing to dbxml - and then for no apparent reason, blow up with
log.0000000001: log file open failed: No such file or directory
PANIC: No such file or directory
When I go look - there is indeed no log.00000001 in my dbxml directory.
What is the story with log.00000001? When is it created? What would cause this creation to fail. I have seen this problem on both an XP system and a Unix system.
I think I have made this problem go away by manually creating an empty log.0000001 file before I start my app - but this seems bogus.
Any tips appreciated

Hi,
If you have multiple applications or processes using Berkeley DB XML (including our utility programs) you may have set up a separate log directory for your log files or they simply were created in another directory. For this reason you may want to consider using a DB_CONFIG file and setting the location for your log files there.
For more information about this please look at these references:
http://www.sleepycat.com/docs/ref/env/db_config.html
DB_CONFIG
http://www.sleepycat.com/docs/api_c/env_set_lg_dir.html
http://www.sleepycat.com/docs/api_c/env_set_data_dir.html
An example for how to insert this information in a DB_CONFIG file is:
set_data_dir datadir
set_lg_dir logdir

How to view weblogic log files from a browser

Hi,
I am running WebLogic Server 7.03 on Solaris 8.
I have one Admin and multiple Managed servers running.
Each creates its own log file.
Is there anyway I can access this log files from the browser ?
In Apache, you can create a link from htdocs dir to the logs dir
and then view the log files from the browser. Is there a similar
mechanism in Weblogic server.
A quick response is well appreciated.
Thanks in advance.
-Anil Varma

If you are on a unix system you can do something similar by making an open
directory webapp with symbolic links to the weblogic log directories. I suggest
that you protect that webapp with administration access only.

How to configure Log file generation

Hi,
I am in a migration project. Currently the OS is Unix. After migration it is going to be Windows.
So we want to change the log files being created in Unix to Windows.
Can anyone suggest any settings in SAP for the log file.
Regards,
Gijoy

Hi Gijoy,
can you please reformulate your question for better understanding?
The log location and tracing severity setup mechanism is platform independent.
After migration there's no necessary step(s) to be taken, the logs will be created in the same way on windows as on unix under your current sap installation folder (e.g. defaultTrace is on unix under /usr/sap/.../j2ee/cluster/server<n>/log , on windows this will be <DRIVE:>\usr\sap\...\j2ee\cluster\server<n>\log)
I hope this answers your question.
Best Regards,
Ervin

Finding Trace File in Unix

Hi,
I am trying to log in, with the user name and password... I am not able to log in to server...
Main issue is the database is not created as per standard path... I want to find the trace files in unix... How it is possible..
Thanks and Regards..

If you are able to login to database then check what is the value for these parameters where the trace file is created (user_dump_dest, background_dump_dest, db_recovery_file_dest)
Also use the unix 'find' command to search for the alert log file and .trc files.

Why is there no error when checkpointing after db log files are removed?

I would like to test a scenario when an application's embedded database is corrupted somehow. The simplest test I could think of was removing the database log files while the application is running. However, I can't seem to get any failure. To demonstrate, below is a code snippet that demonstrates what I am trying to do. (I am using JE 3.3.75 on Mac OS 10.5.6):
public class FileRemovalTest {
public static void main(String[] args) throws Exception

ec.setAllowCreate(true);
ec.setTransactional(true);
ec.setConfigParam(EnvironmentConfig.ENV_RUN_CLEANER, "false");
ec.setConfigParam(EnvironmentConfig.ENV_RUN_CHECKPOINTER, "false");
ec.setConfigParam(EnvironmentConfig.CLEANER_EXPUNGE, "true");
ec.setConfigParam("java.util.logging.FileHandler.on", "true");
ec.setConfigParam("java.util.logging.level", "FINEST");
Environment env = new Environment(new File("."), ec);
// Create a database
DatabaseConfig dbConfig = new DatabaseConfig();
dbConfig.setAllowCreate(true);
dbConfig.setTransactional(true);
Database db = env.openDatabase(null, "test", dbConfig);
// Insert an entry and checkpoint the database
db.put(
null,
new DatabaseEntry("key".getBytes()),
new DatabaseEntry("value".getBytes()));
CheckpointConfig checkpointConfig = new CheckpointConfig();
checkpointConfig.setForce(true);
env.checkpoint(checkpointConfig);
// Delete the DB log files
File[] dbFiles = new File(".").listFiles(new DbFilenameFilter());
if (dbFiles != null)
for (File file : dbFiles)
file.delete();
// Add another entry and checkpoint the database again.

Hi,
OS X, being Unix-like, probably isn't actually deleting file 00000000.jdb since JE still has it open -- the file deletion is deferred until it is closed. JE keeps N files open, where N is configurable.
We do corruption testing ourselves, in the following test by overwriting a file and then attempting to read back the entire database:
test/com/sleepycat/je/util/DbScavengerTest.java
--mark

Errors appeared in alert log file should send an email

Hi,
I have one requirement to do, as i am new dba, i dont know how to do this,
sendmail is configured on my unix machine, but dont know how to send the errors appeared in alert logfile should send an email to administrator.
daily, it has to check the errors in alert log file, if any errors occurs(ORA- errors or WARNING errors) should send an email to administrator.
please help me how to do it

Hi,
There are many methods for interrogating the alert log and sending e-mail. Here are my notes:
http://www.dba-oracle.com/t_alert_log_monitoring_errors.htm
- PL/SQL or Java with e-mail alert: http://www.dba-village.com/village/dvp_papers.PaperDetails?PaperIdA=2383
- Shell script - Database independent and on same level as alert log file and e-mail.
- OEM - Too inflexible for complex alert log analysis rules
- SQL against the alert log - You can define the alert log file as an external table and detect messages with SQL and then e-mail.
Because the alert log is a server side flat file and because e-mail is also at the OS-level, I like to use a server side scell script. It's also far more robust then OEM, especially when combining and evaluating multiple alert log events. Jon Emmons has great notes on this:
http://www.lifeaftercoffee.com/2007/12/04/when-to-use-shell-scripts/
If you are on Windows, see here:
http://www.dba-oracle.com/t_windows_alert_log_script.htm
For UNIX, Linux, Jon Emmons has a great alert log e-mail script.
Hope this helps . . . .
