Adrci - purging alert logs

Been playing around with 11g,mainly with ADRCI (trying to identify what it does, etc...) and from what I can see, based on the documentation, within ADRCI, you can purge incidents, problems, reports, etc...
So, I set my SHORTP_POLICY to 168 (7 fdays), and within ADRCI, if I just type "purge" (or purge -age 60 -type alert), should it not purge the alert logs (I assume it will do both the log.xml and alert_<SID>.log files????).
This doesn't seem to work...Has anyone tried (or worked) with this.
And I also assume that because there are policies (SHORTP_POLICY & LONGP_POLICY), that there is some kind of automated purging process? is this correct?
Thanks

I've read that and a few other related articles. Those are for the database ADR homes, which i'm relatively comfortable with:
You goto ORACLE_BASE for the database oracle user (ie. /u01/app/oracle), cycle through all results in adrci exec="show homes", and do a purge -age XXXXX. Either that, or wait the 7-day rolling purge period in which ADR automatically purges for a SHORTP policy (30 days) or the LONGP policy (365 days).
I'm talking about the grid user. That means the +ASM instance's logs, CRS data/logs, the listener, and scan_listener entries.
my general understanding is for the grid user, adr homes typically reside under:
/u01/app/grid (which is the typical ORACLE_BASE)
/u01/app/11.2.0/grid/log (which is the typical ORACLE_HOME/log)
.. but there are a ton of other things.
MOS 1368695.1 spells out the clusterware log locations and some of their archival policies:
<GRID_HOME>/log/$HOST/alert$HOST.log
<GRID_HOME>/log/$HOST/client
<GRID_HOME>/log/$HOST/racg*
<GRID_HOME>/log/$HOST/srvm
<GRID_HOME>/rdbms/audit
<GRID_HOME>/log/diag/*
I've been told by ora support that these dir's are not auto-rotated.. have to be manually handled by the DBA. Some of these dir's under $GRID_HOME/log/<server_name>/ . . ., and they are owned by both ROOT and GRID users. So I was wondering how the rest of the community is dealing with it? How large have people typically made their /u01/app filesystems? Have they done purging via a cron script under the grid user or root user?

Alert log in 11g

Hi,
I have a database where it started on 20th Jun, but my alert_sid.log contains entries starting from 27th Jun. Database version is 11.2.0.2
I know ADRCI purges only log.xml, but wondering why i'm unable to see the old entries in alert_sid.log. Can someone pls let me know why is this.
Thanks,

Most Recent Alert Log Entries - Error processing Alert Log

Hi..
Can someone help me?
When I want to check the log of alerts the following thing goes out for me:
"This shows the last 100,000 bytes of the alert log. The log is constantly growing, so select the browser's Refresh button to see the most recent log entries.
Number of Lines Displayed Error processing Alert Log"
Since I can solve it?

Number of Lines Displayed Error processing Alert Log"
check ur alert.log file content any data.
bcoz if ur alert.log file entries is null then above error is show. ( happen with me when i am purge alert.log file and try to view content of alert.log then above error received so may be problem is null contents ( empty alert.log file)).

12c Cloud Control Alert Log Purge Error

I'm trying to purge old alert log events in EM 12c, but i'm getting error - The alert(s) could not be purged. Please ensure you have Edit privileges on this target while purging.
What's i'm doing wrong? Cant find anything close to this in EM documentation.
Thank you.

Hi,
What privileges do you have on the target? You'll need at least Manage Target Events (a subprivilege of Operator) in order to clear events on the target.

Purging the ALERT LOG

Hi,
I am using RDBMS : 9.2.0.6.0 on AIX 5.3 platform.
I want to purge my alter log file as it is never been purged and is almost contains the entry of past 1 year.
Can you please provide me the way to do it?
Thanks
Shivank

If there is no alert log the database will create another one, so you can remove/delete the alert log file.
If you don't want to delete the alert log file. You can rename it while the database is down. So it will create and use a new alert log file.
You can also empty the file as follows;
cp -p alert.log alert.log.date (backing up the alert log file)
echo ""> alert.log (empty the alert log file)
You can also use as follows;
tail -3000 alert_test01.log > alert_test01.log_new (this will take last 3000 lines).
Additionally specifying your O/S would be helpful.

Trim the alert log?

i have a alert log in <grid home>/log/<node>/alert<node>.log that is growing in size and is also owned by root. is this just like a DB alert log and if I rename it a new one will be created. i'm not sure how to maintenance this log file and I don't want to guess - any suggestions or documentation are appreciated.
thanks.

You can use the ADRCI to manage (purge,etc..) the logs of Oracle.

DG Observer triggering SIGSEGV Address not mapped to object errors in alert log

Hi,
I've got a Data Guard configuration using two 11.2.0.3 single instance databases. The configuration has been configured for automatic failover and I have an observer running on a separate box.
This fast-start failover configuration has been in place for about a month and in the last week, numerous SEGSEGV (address not mapped to object) errors are reported in the alert log. This is happening quite frequently (every 4/5 minutes or so).
The corresponding trace files show the process triggering the error coming from the observer.
Has anyone experienced this problem? I'm at my wits end trying to figure out how to fix the configuration to eliminate this error.
I must also note that even though this error is occurring a lot, it doesn't seem to be affecting any of the database functionality.
Help?
Thanks in advance.
Beth

Hi..   The following is the alert log message, the traced file generated, and the current values of the data guard configuration. In addition, as part of my research, I attempted to apply patch 12615660 which did not take care of the issue. I also set the inbound_connection_timeout parameter to 0 and that didn't help either. I'm still researching but any pointer in the right direction is very much appreciated.

Alert Log file

Hi,
I'm new at administrating a database (11.2.0.2 on OEL).
1) How often one need to see the alert log file?
2) Why are some Oracle errors not logged in the Alert Log?

Hello,
I wouldn't look in the alert log for performance problems either. At least not immediately, but I would take a quick look in there to see if there were any major problems. The alert log is a good place to look first to check the overall health of the DB because any major errors will be written there.
You can use the Enterprise Manager to automatically email you if certain errors are raised in the alert log.
Also, you can search through the alert log using the [url http://www.ora00600.com/wordpress/scripts/databaseconfig/adrci/]ADRCI utility which can be pretty useful.

10.2.0.4 Streams Alert log message

Good afternoon everyone,
Wanted to get some input on a message that ocasionally is logged to alert log of the owning QT instance in our RAC environment. In summary we have two RAC environments and perform bi-directional replication between the two environments. The message in question is usually logged in the busier environment.
krvxenq: Failed to acquire logminer dictionary lock
During that time it it seems that the Logminer process in not mining for changes, which could lead to latency between the two environments.
I have looked at AWR reports for times during the occurence of these errors and its common to see the following procedure running.
BEGIN dbms_capture_adm_internal.enforce_checkpoint_retention(:1, :2, :3); END;
This procedure, which I assume purges Capture chekcpoints that exceed the retention duration, takes between 10-20 minutes to run. The table which stores the checkpoints is logmnr_restart_ckpt$. I suspect that the issue could be caused by the size of the logmnr_restart_ckpt$ whcih is 12GB in our environemnt. A purge job needs to be scheduled to shrink the table.
If anyone has seen anything similar in her or his environment please offer any additional knowledge you may have about the topic.
Thank you,

There are 2 possibilities : either you have too much load on the table LOMNR_RESTART_CKPT$
due to the heavy system load or there is a bad streams query.
At this stage I would not like to admit the 'we-can't-cope-the-load' without having investigated more common issues.
Let's assume optimistically that one or many streams internal SQL do not run as intended. This is our best bet.
The table LOMNR_RESTART_CKPT$ is big is a perfect suspect.
If there is a problem with one of the queries involving this table, we find it using sys.col_usage$,
identify which columns are used and from there jump to SQL_ID checking plans:

select r.name ||'.'|| o.name "obj" , c.name "col1",
      equality_preds, equijoin_preds, nonequijoin_preds, range_preds,
      like_preds, null_preds, to_char(timestamp,'DD-MM-YY HH24:MI:SS') "Date"
from sys.col_usage$ u, sys.obj$ o, sys.col$ c, sys.user$ r
where o.obj# = u.obj#    and o.name = 'LOMNR_RESTART_CKPT$'    -- and $AND_OWNER
        c.obj# = u.obj#    and
        c.col# = u.intcol# and
        o.owner# = r.user# and
       (u.equijoin_preds > 0 or u.nonequijoin_preds > 0)
   order by 4 desc
For each column predicate checks for full table scan :

order by sql_id, PLAN_HASH_VALUE, id
now for each query with a FULL table scan check the predicate and
see if adding and index will not improveAnother possibility :
One of the structure associated to streams, that you don't necessary see, may have remained too big.
Many of these structures are only accessed by streams maintenance using Full table scan.
They are supposed to remain small tables. But after a big streams crash, they inflate and whenever
the problem is solved, These supposed-to-be-small remain as the crash made them : too big.
In consequence, the FTS intended to run on small tables suddenly loop over stretches of empty blocks.
This is very frequent on big streams environment. You find these structures, if any exists using this query
Note that a long running of this query, imply big structures. You will have to assess if the number of rows is realistic with the number of blocks.

How to check particular error in alert log file

Hi all,
How to check particular error in alert log file,for supose if i get error in batabase yesterday 4 pm & today i want to check alert log file to get basic idea..it might be a big file so how to check that particular error..
Thanks & regards,
Eswar..

What's your oracle version?
If you are in 11g you can use adrci tool
1- set homes diag/rdbms/orawiss/ORAWISS/ : the rdbms home
2- show alert -P "MESSAGE_TEXT LIKE '%ORA-%'" -term : to find all the ORA-% errors in the alert file
3- show alert -P "MESSAGE_TEXT LIKE '%ORA-%' and originating_timestamp > systimestamp-51 " -term : to find all the ORA-% errors in the alert file during the last 51 days,
4- show alert -P "MESSAGE_TEXT LIKE '%ORA-%' and originating_timestamp > systimestamp-1/24 " -term : to find all the ORA-% errors in the alert file during the last hour,
5- show alert -P "MESSAGE_TEXT LIKE '%ORA-12012%' and originating_timestamp > systimestamp-1/24 " -term : to find the particular ORA-12012 error in the alert file during the last hour,

If alert log is deleted, how to restore it?

Hi,
I want to know if Alert log is deleted, how to restore it?

RMAN does not backup the alertlog, only an OS filesystem backup does this. In 11g and higher there are 2 versions of the alertlog, the well-known textfile and now additionally a file in xml format. IF only the text version is lost, command line utility adrci can still access the xml file:
http://docs.oracle.com/cd/E11882_01/server.112/e22490/adrci.htm#BGBBBBEA

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
Regards
Mohammed.

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.

Alert log

Hi,
How to use the alert log in production ENV.Bcz the alert log size is 1.6GB.it is difficule to handle.
Is there any tool.
can i get the last one day info from alert.log file?
Edited by: user3266490 on Nov 16, 2009 11:55 AM

You can purge the alert log file according to your need. You can remove the alert log file also. This won't hamper your running database.
]$ tail -f alert_syslog.log -- to see running alert log files
$ tail -200 alert_syslog.log --to see last 200 lines

How to view alert log?

I tried clicking on the xml alert log, but it goes into IE and tells me "Cannot view xml input using xsl style sheet...Only one top level element allowed in an xml document". I don't see any adrci, and I can't find any text file alert log? trace directory only has files beginning with cdump. database and dbs directories don't have it. And nothing about it in the docs?
I hope I'm missing something obvious. The database is running. XP Pro SP3.

Hello Joel,
the good old text alert log is still there, it just moved a bit. The default location would be ORACLE_HOME\diag\rdbms\xe\xe\trace, e.g. D:\oracle\product\database_xe_11_2\app\oracle\diag\rdbms\xe\xe\trace for the instance on my machine.Yep, that's the trace directory I was looking in, it only has an xml.
See this thread for further hints: {thread:id=2281565}(You had an extra ampersand in the thread id). Yeah, 'Diag Trace' says same directory.
Anyone know how to get the css right? I'm clueless about such things.

Clusterware 12.1.0.2.0: Alert Log is empty

Also other logs , like css, crsd are empty.
This is a extrange issue, never seem for me.
The Linux servers are installed in Spanish.
Red Hat Enterprise Linux Server release 6.5 (Santiago)
However, if I change the environment variables to English.
The messages are coming out in Spanish.
Then If I execute any crsctl command from GRID user:
[grid@rac1 ~]$ crsctl check cluster -all
rac1:
CRS-4537: Cluster Ready Services estÃ¡ en lÃnea
CRS-4529: Cluster Synchronization Services estÃ¡ en lÃnea

rac3:

CRS-4529: Cluster Synchronization Services estÃ¡ en lÃnea

The messages are in Spanish, there seems to me this reading the env variables.
The .bash_profile for GRID user is:

You know that it can be happening?
Many thanks

Hello,
Thanks for you answer.
Yes, If I use adrci from the grid user:
adrci> show alert
Choose the home from which to view the alert log:
1: diag/clients/user_grid/host_203307297_82
2: diag/clients/user_oracle/host_203307297_82
3: diag/rdbms/_mgmtdb/-MGMTDB
4: diag/asm/+asm/+ASM1
5: diag/tnslsnr/rac1/listener
6: diag/tnslsnr/rac1/mgmtlsnr
7: diag/tnslsnr/rac1/asmnet1lsnr_asm
8: diag/tnslsnr/rac1/listener_scan2
9: diag/tnslsnr/rac1/listener_scan3
10: diag/tnslsnr/rac1/listener_scan1
11: diag/crs/rac1/crs
Q: to quit
The 11 option, go to /u01/app/grid/diag/crs/rac1/crs/trace/ alert.log.
Here in this directory are all the Crs trace files, including css, crsd components etc.
Well,, I think is a small change of 12c.
Thanks again.

Arturo
