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.

Which background process writes date into alert log file in oralce

which background process writes date into alert log file in oralce

Hi,
AFAIK, all the background process are eligible for writing information to alert log file. As the file name indicates to show the alerts, so background process have the access rights in terms of packages (dbms), to write to alert log.
I might be wrong also..

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.

"checkpoint not complete" in alert log file.

Hi, all.
I have got a message of "Checkpoint not complete" in alert log file.
Thread 2 advanced to log sequence 531
Current log# 7 seq# 531 mem# 0: \\.\REDO231
Current log# 7 seq# 531 mem# 1: \\.\REDO232
Thread 2 cannot allocate new log, sequence 532
Checkpoint not complete
Current log# 7 seq# 531 mem# 0: \\.\REDO231
Current log# 7 seq# 531 mem# 1: \\.\REDO232
I searched "Checkpoint not complete" issue in this forum.
As solutions,
1. add more redo log groups
2. increase the size of redo log
3. check I/O contention
4. set LOG_CHECKPOINT_INTERVAL, LOG_CHECKPOINT_TIMEOUT or
FAST_START_MTTR_TARGET
I think No.4 is the possible first approach in our environment.
I think No.1 and No2 are not the ploblems in our environment.
I ask the above issue oracle support center, but
I was told that "if you are not getting this message frequently, you do not need to worry about it" from an oracle engineer.
Is this true?? If I am not getting this message frequently, there is no problem
in terms of database integrity, consistency, and performance?
I will be waiting for your advice and experience in real life.
Thanks and Regards.

Redo Log Tuning Advisory and Automatic Checkpoint Tuning are new features introduced in Oracle 10G, if you are on 10g you may benefit from these features.
The size of the redo log files can influence performance, because the behavior of the database writer and archiver processes depend on the redo log sizes. Generally, larger redo log files provide better performance, however it must balanced out with the expected recovery time. Undersized log files increase checkpoint activity and increase CPU usage. As rule of thumb switching logs at most once every fifteen minutes.
Checkpoint frequency is affected by several factors, including log file size and the setting of the FAST_START_MTTR_TARGET initialization parameter. If the FAST_START_MTTR_TARGET parameter is set to limit the instance recovery time, Oracle automatically tries to checkpoint as frequently as necessary. Under this condition, the size of the log files should be large enough to avoid additional checkpointing due to under sized log files.
The redo logfile sizing advisory is specified by column optimal_logfile_size of v$instance_recovery. This feature require setting the parameter "fast_start_mttr_target" for the advisory to take effect and populate the column optimal_logfile_size.
Also you can obtain redo sizing advice on the Redo Log Groups page of Oracle Enterprise Manager Database Control.
To enable automatic checkpoint tuning, unset FAST_START_MTTR_TARGET or set it to a nonzero value(This is measured in seconds and by default, this feature is not enabled, because FAST_START_MTTR_TARGET has a default value of 0). If you set this parameter to zero this feature will be disabled. When you enable fast-start checkpointing, remove or disable(set to 0) the following initialization parameters:
- LOG_CHECKPOINT_INTERVAL
- LOG_CHECKPOINT_TIMEOUT
- FAST_START_IO_TARGET
Enabling fast-start checkpointing can be done statically using the initialization files or dynamically using -
SQL> alter system set FAST_START_MTTR_TARGET=10;
Best regards.

Shell script for oracle alert.log file

Hi Gurus,
I wanted to write shell script to know the last 10 shutdown timings of the database from alert log file. I'm working on oracle 9i.
Could anyone please advice on this.
Thanks in advance

Shaan

Use awk. I don't have a 9i to hand but here is a very simple version for 10g XE
My awk file (the line numbers are for the notes below - don't include them:
01:BEGIN { prevline = "";}
02:
03:/Completed: alter database close/ {print prevline,FS,$0;}
04:
05:{prevline = $0;}The command line and results (from my 300k alert log)

Tue Dec 09 10:46:23 2008   Completed: alter database close normal
Mon Jan 05 11:12:22 2009   Completed: alter database close normalWhat it means:
1) the BEGIN section at line 01 defines the variable to hold the previous line
2) the /search string/ at line 03 finds the marker in the file for a shutdown, then does the required action (print the time which was in the previous line, and then this line; use FS (the awk field separator - normally space) as a separator
3) at line 05 is an instruction we do on every line - so we remember it in case it is the timestamp for the shutdown.
Now, you can include more of the corner cases for shutdowns by adding more search patterns etc. For more information, google for awk examples.
Awk is really good at this sort of thing!

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.

but when i am trying to find out in bdump folder i cannot found
any file with this named. instead i found /bdump/stlbas_cjq0_1853.trc
is there any possibility of being this scenario ?

The trace file has been removed/deleted from an OS user. I think you should verify that with OS logs.

This parameter, FAST_START_MTTR_TARGET ranges from 0 to 3600 seconds. It is important to specify your oracle version, since a similar issue is reported for the 10gR1 release.
The solution for it would be to increase the value to the suggested one in the alert.log file, but it could be completely out of range from the valid values, so set it to zero and let the oracle instance calculate the value. You can check the output at the V$INSTANCE_RECOVERY view at the columns TARGET_MTTR, and ESTIMATED_MTTR prior to proceeding with modificaiton.
On the other hand, I suggest you to read this metalink note
Kkjcre1p: Unable To Spawn Jobq Slave Process, Error 1089
Doc ID: Note:344275.1
for the Kkjcre1p error message.

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 . . . .

Does anyone know why? Thanks.

I'm not sure if this will answer your question or not, but I believe these messages can likely be ignored.
I'm currently running 10.2.0.1.0 Enterprise Edition in pre-production (yes, I know I should apply the latest patchset and I plan to do so as soon as I get a development box allocated to me and can test it's impact). I see the same types of messages that you've reported with each of my regularly-scheduled backups:
a) The alert_<$SID>.log reports that there are errors in trace files:
Mon Aug 10 04:33:49 2009
Starting control autobackup
Mon Aug 10 04:33:50 2009
Errors in file /opt/oracle/admin/blah/udump/blah_ora_32520.trc:
Mon Aug 10 04:33:50 2009
Errors in file /opt/oracle/admin/blah/udump/blah_ora_32520.trc:
Mon Aug 10 04:33:50 2009
Errors in file /opt/oracle/admin/blah/udump/blah_ora_32520.trc:
Control autobackup written to DISK device
handle '/backup/physical/BLAH/RMAN/cf_c-2740124895-20090810-00'
b) The .trc files, when you look at them contain no errors - only these "informational" messages:
*** 2009-08-10 04:33:50.781
*** ACTION NAME:(0000105 STARTED111) 2009-08-10 04:33:50.754
*** MODULE NAME:(backup archivelog) 2009-08-10 04:33:50.754
*** SERVICE NAME:(SYS$USERS) 2009-08-10 04:33:50.754
*** SESSION ID:(126.28030) 2009-08-10 04:33:50.754
c) I've verified that LOG_ARCHIVE_TRACE is set to 0:
SQL*Plus> show parameter log_archive_trace
NAME TYPE VALUE
log_archive_trace integer 0
As best I can discern from my own experience, these should just be ignored and I trust (read: "hope") they will simply go away once the latest patchset is applied. As for you running Oracle XE, a patchset is not an option, unfortunately.

ORA- errors in alert log file

I wanted to know when the ORA- errors are reported into the alert.log file?
And which tye of errors are reported into it?
And if i wanted to log all the ORA-errors in the alert log then is there any setting for that?

You can find the type of errors reported in the link above.
Also, you maynot like to log ORA-00942: table or view does not exist, ORA-00904: : invalid identifier type of errors in alert.log - right? You may want to research at setting up events for generating trace files on specific error numbers you are looking at. That might resolve your problem - hth.

thank you in advance,

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.

Checkpoint not complete in alert log file Oracle 11gR2 RAC

Hi,
I found checkpoint not complete in alert log file, almost every 3 seconds .
In metalink i saw for this error, archive_lag_target=0, already this value was set to 0 in my database.
We have 7 redo log groups for each instance, each group is of two redo log files, each file size is 50m.
To avoid this error what i need to do..........
please help me..................

When you "checkpoint not complete" messages in your alert log this normally means your online redo logs are defined too small to handle the load and you have filled and need to switch to a new online redo log before the checkpoint triggered by the previous log switch has been completed.
Increasing your online redo log size is normally the fix for this.
