Alert log contains ARCH and FRA mount/dismount messages

Hi Guys,
We see messages like:
SUCCESS: diskgroup DBNAME_ARCH was mounted
SUCCESS: diskgroup DBNAME_ARCH was dismounted
SUCCESS: diskgroup DBNAME_FRA was mounted
SUCCESS: diskgroup DBNAME_FRA was dismounted
in our alert.log file for a RAC DB. This message coincides with the creation of archive logs.
Do we know why DB keeps on mounting and dismnounting these diskgroups?
Why not keep them mounted as long as the database(instance) is up? Is it because these diskgroups dont have any live db file that they are dismounted as soon as the archive log is created?
Any suggestions/ideas would be welcome.
Regards.

Hi,
There is a metalink Note:361173.1 which states that this is an expected behavior. So you can ignore these messages.

Customize alerts on ALERT.log file? And another question

We just setup and have started to use Grid Control. So far, I have been very pleased with what I have seen.
Just some questions though.
Is there a way to customize the "Generic Alert Log Error Status"?
Can we have exclusions for that alert? We get are getting messages on alerts for a bug that exists in one of our DB's. If we can some how exclude this particular error, that would be great. That possible?
Secondly, can you schedule checks on a database to check the state of the database? This is something I would like to do if possible.
THanks.

Go to targets - databases - <database>
On this page on the left side, you'll see a heading "Diagnostic Summary"
The you'll see something like:Alert Log <date>
Click on the date, go to the bottom of the page and click on "Generic Alert Log Error Monitoring Configuration"
Here you can configure exactly what alert log messages you want.
Yes, depending on what it is you want to do. Look at User Defined Metrics, Reports and possibly Jobs to see what fits best with want you want to do.

Rogue alert log in $ORACLE_HOME/dbs

Hi there, have looked all over and not yet found the answer to my query. I have a database instance running at 10.2.0.4.0. There is a rougue alert-{ORACLE_SID}.log created in $ORACLE_HOME/dbs directory when an instance is started. Show parameter background_dump_dest points to the correct directory - $ORACLE_ADMIN/$ORACLE_SID/bdump wether using spfile or pfile. To confirm what is happening I shutdown the instance and deleted both alert logs from the two locations and restarted the instance. Again two alert logs were created. Can anyone please advise why this is happening. I have found threads suggesting that logs are created in $ORACLE_HOME/dbs as default if parameters are not set correctly, but this is creating an alert log in two locations at startup.
in $ORACLE_ADMIN/$ORACLE_SID/bdump/alert_DBAASS06.log shows -

Adjusting the default value of parameter parallel_max_servers

Thanks for the reply. The cloned database source looks like it uses spfile on startup on the test box, but as I hadn't checked this at the time it was cloned, the spfile was not copied over, so I'm assuming it would have used the default init.ora created which had the correct dump dest defined. As for the new database, it was created from scratch, so I don't see why this should not work correctly. Unfortunately as I am new to this establishment, I have no history as to how Oracle was installed on either machine or how any of the other databases were created, though I do understand that many may have been cloned.
So while I can't speak for the databases that already existed on the Dev box, it seemed weird that they all appeared to be doing the same thing. So I found one that hadn't been started for a while for which there was no historic alert log in dbs and started it to see what happened. It had no spfile, started with pfile and did not create a rogue log. I created an spfile and restarted and still no rouge log. I ran show paremeters and compared to another similar database that had a rougue log, DASSEN02 v DASSEN04 and the only differences were with the instance name and all the files (bdump, cdump etc) existed correctly. Had a further look ref RMAN as some but not all databases had snapcf files in the dbs directory, but again some that had snap files had rougue alert files and others didn't. Also double checked file permissions on the bdump directory, no issues there. Unexplained issues really do bug me, but I think I'll just have to live with not knowing for now, till I have a spare few hours to look at again.

Alert log/trace file

alert log file is generated daily or it will be updated daily?
is trace file part of alert log file or its a seperate file?
how trace file differ's from alert log file.?
thankx....

>>

When oralce starts every first time, oracle does create a alert log file and whenever oracle wants to update the alertlog file, it updates the existing one and in case of missing alert log, it re-create the alert log and updates it.
>>

>>
No.
>>

alert log contains database activities list carried out in the related database.
trace file can be generated due to number of reasons, like, hardware problems, due to oracle internal errors, user errors, whenever you trace a session and etc.

Working on following environment:
Platform -> Windows Server 2003 Version V5.2 Service Pack 2 32-bit
Oracle Database -> 10.2.0.1

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.

Ora Errors in Alert Log:ORA-27508, ORA-27507, ORA-27300, ORA-27301

Hi All,
I have a Solaris 5.9 machine with Oracle 9.2.0 installed on it. But the connectivity to the database is lost intermittently.
I am getting the below mentioned message in the Alert Log:
ORA-27508: IPC error sending a message
ORA-27507: IPC error disconnecting from a port
ORA-27300: OS system dependent operation:DIS: NCON: connect failed: cnh 0 failed with status: 134
ORA-27301: OS failure message: Transport endpoint is not connected
ORA-27302: failure occurred at: skgxpdis
ORA-27303: additional information: DIS: NCON: connect failed: cnh 0x1039208e8, rqh 0x10391bfb8
After searching a lot on various forums, I could not get any resolution to the above errors.
Could someone please help me out with this issue.
Thanks a lot in advance.

This was already clear from the initial error.
Your interconnect is functioning badly.
You need to address the errors 27300 and 27301.

Find time when DB went down (nothing in alert log).

hello all,
is there any way to tell when the DB went down. Yesterday we had some outage in our datacenter and it took down one of our servers. And this morning i started the DB and they went up fine with no problem. But is there any way to find out when the DB went down (there was nothing written in the alert log)...and our sysadmin is on Vac...and the management wants me to find out when the server/database went down...does oracle record this thing any place in the DB besides the alert log ?? we are on 10.2.0.3 on hp-ux. We can look at the OS to find this out, but as mentioned our sysadmin is out and dont have access to root...

Hello user630084,
Pls try this. I had to check the same on one of our client boxes without unix access and I used the below to find. it worked for me.
(10.2.0.4 version)
SELECT SCN_TO_TIMESTAMP(TIMESTAMP_TO_SCN(startup_time)) "DB Shutdown Time" , startup_time "DB Startup Time" FROM v$instance
Hope this works for u aswell.

Settinggs for Generic Alert Log Metric, OEM GC 10204

OS: AIX Grid Control Version: 10204
Agent:10204, Repository DB:10204
This is the setting on a 9208 DB I was testing for Generic Alert Log Error Metric (I had to change [ (square bracket with { curly brackets on the post).
Warning Metric: ORA-*
Critical Metric: ORA-0*(60{0-9}|1157|1562|1628|1650|1653|1654|1655|1656|4031|7445|16014|29740){^0-9}
The Warning metric (ORA-*) is set to a catch all else if not found in the critical metric. Not sure if there's an order the warning vs critical is read, but so far this has worked for our purposes.
In GC 10204, we can add an ORA- error to the 'Alert Log Filter Expresion' and this would prevent a metric from being sent out if matched, so if there's a particular ORA-0600 error we do not want to be sent out as critical, we could add it to to the filter to be ignored. In the Advance Setting GC example , we want to ignore "ORA-00600: internal error code, arguments {qerfxFetch_01}, {}, {}, {}, {}, {}, {}" , so we would added it to the filter as ".*ORA-00600:.*\{qerfxFetch{^\}}*\}.*"
My question - Instead of ignoring the error "ORA-00600: internal error code, arguments {qerfxFetch_01}, {}, {}, {}, {}, {}, {}", I want to move it to be a Warning, can anyone suggest any way of doing this? I've tried adding to the Warning metric {.*ORA-00600:.*\{qerfxFetch{^\}}*\}.*}|ORA-*, but this does not work, as the alert still comes out as a critical.
All suggestions are welcome.

Hi,
You did not mention database version. in 11g, the generic alert log metric will not work. For 10g, you can set this from metrics and policy settings page bu setting warning and critical thresholds for this metric to "ORA-*". And then create a notification rule for this metric.
For 11g, you need to check MOS note 949858.1

Alert Log Management

Hi All
My database is on Windows machine OS version MS Windows 2003 SP2 64 bit with genuine intel processor from EM 64T family. The alert log is expected to capture all error messages and for a DBA it points one of the most important trouble shooting areas if any problem with the database is referred to .. also does it grow continuously as the database ages in time ..
Earlier on UNIX machines I used to backup the alert log file for future referance and then would trim the file size so that it wont grow beyond manageable limits.. I was using vi editor, cp command and other unix filters like head etc..
but on windows we do not have the filters .. neither could I open the alert log file trim the top few lines and save it so that its size is still manageable by the os.. I am at the moment clueless as to how could I do this activity.. I was doing some google offlate and learnt that for listener log, we have some options like
lsnrctl set file_name <NEW LOG FILE_NAME>
to refresh the listener log to a new file and thus avoid it growing huge in size. Do we have any such fascility for managing alert log as well? It would not always be possible to shut down the database just to trim the alert log file.. and on windows I am not sure about other options..
Thank you ..
Sarat.

Here is from a previous post:
I've been managing Oracle database mostly on Linux for years. Now I'm in an all windows shop and need a script to check my alert logs. Batch programming is junk, can't be trusted, errorlevel is worthless, so I wrote this little program.
This is the begining of alert_log_checker.vbs
' Check the alert log for errors, then send email and rename file
' takes the alert log location as the 1st parameter
Set oArgs = WScript.Arguments
' Set this to the log you want to check for or pass it in. currently its passed in
v_alert_log = oArgs(0)
' Set this to the text pattern you want to grep for
v_pattern = "ORA-"
v_mail_to = "[email protected]"
Set objNet = CreateObject("WScript.NetWork")
v_computername = objNet.ComputerName
v_mail_from = v_computername & "@someplace.com"
' Check if the file exists
if FileExists(v_alert_log) = FALSE then
'wscript.echo "No log file" & v_alert_log
Wscript.quit(0)
end if
' Grep the log
v_grepResults = GrepFile(v_alert_log,v_pattern)
if v_grepResults = "" then
'wscript.echo "Log is empty"
wscript.quit(0)
else
' send email concerning alert
Set WshShell = WScript.CreateObject("WScript.Shell")

Cloud Control 12c monitoring Oracle 11g Standard Edition alert.log

Hi guys.
I just installed Cloud Control 12c3 and added my cluster database, I have readed many papers, tech docs and tech discuss and now i have a huge confussion about packs, licensing and other fruits. Please help...
I have four Oracle 11g databases (differents hosts) Standard Edition, and i want monitoring and notificate alert.log errors. For example, if alert.log says "ORA-01438, blablabla" i want a email notification.
I read about packs, and says that "diagnostic pack" is needed for alert.log monitoring in Cloud Control 12c. But my version database is Standard Edition without packs, so I CAN'T MONITORING ALERT LOG!!!.
Question:
Do I really need Diagnostic Pack for monitoring alert.log with Cloud Control?
If Diagnostinc Pack is not necessary, how can i monitoring alert.log?
Thanks

I do not think you require any pack for alert.log content monitoring but you might need to check with Oracle rep. I am saying so because if you go to the "Alert log content" page and click on management pack for this page, Grid will display a message that this page does not require any pack.
Go to the Alert log content by "oracle database -> logs -> alert log contents"
then
go to SETUP -> management packs -> packs for this page
You will see the message will be displayed " this pages does not require any pack"
Can you also provide the doc where it says that this pae needs diagnostic pack?

Alert log rotation/OS Audit log rotation

Hi all,
Is there away that I can fix of my audit and alert log size to 100Mb and it will just reuse or rotate around it?
Or can manipulate it thru OS programs?
Thanks,
zxy

You can limit the OS audit file size using the package called DBMS_AUDIT_MGMT
Refer http://docs.oracle.com/cd/E11882_01/appdev.112/e25788/d_audit_mgmt.htm
However, for limitting alert log file size, you need to setup a OS job, which periodically checks the alert log file size and then does a rename of the alert log file.

Errors in alert log and listener log and "alter database mount exclusive"

Hello!
I need a help.
Database 11R2 works under MS Windows Server.
Whwn I start it using Services, according alert log it is started by command "alter database mount exclusive".
Next - alter database open.
After this, it seams that program, which should put data into database, can not work with it, because I see errors in alert log: ora-12537, 12560, 12535, 12570, 12547.
What does itmean and what to do?
This is extract from alert_log
