Alert log file of the database is too big

Dear Experts?
Let me update you that we are in process of doing an R12.1 upgrade ? And Our Current Instance is running on the 11.5.10 with 9.2.0.6 ?
We have the below challenges before going for an database upgrade ?
We have observed that the customer database alert_SID.log (9.2.0.6) size is 2.5GB ? how to purge this file ? Please advise
Please also note that our Instance is running on the Oracle Enterprise Linux 4 update 8

Mohammed.Rename the alert logfile. once you rename the logfile another alert log file will create and being populated with time, and later you can delete it old alert log file . it doesnot harm your database.

Message in alert log file during the startup of the DB

Hi,
i have two instances, i have the same warning in the alert log file during the startup of the DB:
Oracle instance running on a system with low open file descriptor limit.
Tune your system to increase this limit to avoid severe performance degradation.
The db_files parameter was at 1024 for the two instances, i have set it to 300 for the first instance and 550 for second, the message for the first instance was droped(it's ok), but the message was there in the alert log for the second instance.
The two instance are on the same machine.
The number of the open file limit on the linux machine is equal to 1024.
I have shutdown the first instance (with db_files=300) the problem persits for the second instance (with db_files=550).
My question is how to determinate the right value of db_files parameter to avoid this message.
Regards.

Increase the max number of open file on Linux or decrease db_files.
f the OS limit is 1024 db_files would have to be >= 472 for the message to be printed. t is printed if an instance is configured to access more datafiles than the OS-specific limit on the number of files that can be open in a single process. In this case the server will re-cycle the file descriptors.

Receiving Alerts on ORA- error in Alert Log File

Hi,
I am using 10.2.0.5 OEM grid control and same versioned agent on my database servers. I have configured the alert email notification if there is any ORA- error message in my alert log file. The metric i selcted for this is "Generic Alert Log Error Status". In notification email, i see only the message that there is generic error message in the alert log file. Is there any way to set this notification so that i receive the exact ORA- error message in my alert notification email if there is any kind of ORA- error found in my alert log file?
Thanks
Salman

Please look into the Metalink Note: 458605.1
Subject: Receiving "Clear" Notifications Unexpectedly for 'Generic Alert Log Error Status' Metric

ORA-01555 in alert log file

Hi,
I am occasionally seeing ORA-01555 in the alert log file, but the query length is so long that I could not see the full query in the alert log file.
Where can i view the query which is causing this issue?
Thanks
SA

You can see the full query by using below query, just put the respective sql_id.
SELECT
SUBSTR(SQL_TEXT, 1 + (i - 1) * 80, 80) SQL_TEXT
FROM
DBA_HIST_SQLTEXT HST,
(SELECT ROWNUM I FROM DBA_HIST_SQLTEXT WHERE ROWNUM <=
60)
WHERE
HST.SQL_ID = '&SQL_ID'
And according to query length and undo space available please set the undo_retention appropriatley.
regards
Jafar

Will the informations be recorded in the alert.log file? -----No.168

will the informations about the loss of a temporary file be recorded in the alert.log file?

Yes, because whe your database starts needs to "mount" a tablespace with temporary files (case of tablespace "TEMP"). But don't worry with a loss of this tablespace because doesn't contain nothing when database starts.

I just google with "ORA-44003: invalid SQL name" and found below link:
http://www.oracle-base.com/articles/10g/dbms_assert_10gR2.php
SIMPLE_SQL_NAME
The SIMPLE_SQL_NAME function checks the input string conforms to the basic characteristics of a simple SQL name:
The first character of the name is alphabetic.
The name only contains alphanumeric characters or the "_", "$", "#"
Quoted names must be enclosed by double quotes and may contain any characters, including quotes provided they are represented by two quotes in a row ("").
The function ignores leading and trailing white spaces are ignored
The length of the input string is not validated.

You are having problems on disks E\ and F\ - possibly hardware problems.
(Hopefully these disks are not network drives. If they are, your problem might be network contention. Network mounted drives are never a good idea for databases.)
If this is truly urgent, then I encourage you to use your Oracle Support contract to open a service request for assistance.

How to read trace files alerted in the alert.log file

Hello,
My alert.log file indicated multiple trace files to review. How to read these trace files to understand the cause of errors. Do I open the trace files with vi and do a search for 'ORA-' error. Are there tools to read and understand trace files. Thank you.

It depends what kind of trace file it is.
You can use vi or other text editing tool to open the trace file. The trace file usually provides more detailed information when you have ORA- errors in alert.log. It's also very helpful for Oracle support when troubleshooting.

Prevent message to go to the alert.log file

Hi
How can I prevent any message (for exm. SHUTDOWN IMMEDIATE) to be written to alert.log file? Is it possible?
Thanks
John

Of course this can be done with some scripting, but alot of work and totaly worthless, why dont you want it to be shown in your alert log?
if shutdown immediate present
then cache alert log, rewrite it to new alert log without the text shutdown immediate, but as i said earlier, useless. :)

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 . . . .
