AWR setting
Hi All,
I'm having one database running on Solaris 10 and oracle version 10.2.0.1. I wants to change the AWR setting to 1 hr from EM but after setting the AWR interval to 1hr after some time I found again it has resetted to 10 min. But I did it for another database which is running on same platform and on same version there it has work. Can any body tell me how to change the ARW settings or what kind of privileges are required. I did it using sys user.
Hi ,
Some tips about the AWR..
SYS>alter system set "_swrf_mmon_flush" = true;
How to Modify the AWR SNAP SHOT SETTINGS:
=====================================
BEGIN
DBMS_WORKLOAD_REPOSITORY.modify_snapshot_settings(
retention => 43200, -- Minutes (= 30 Days). Current value retained if NULL.
interval => 30); -- Minutes. Current value retained if NULL.
END;
Creating the Baseline:
======================
BEGIN
DBMS_WORKLOAD_REPOSITORY.create_baseline (
start_snap_id => 10,
end_snap_id => 100,
baseline_name => 'AWR First baseline');
END;

Strange fc scsi_vhci timeouts during heavy disk activity
After a recent hardware upgrade, I noticed strange timeouts while replicating a zfs pool under Solaris 11. They all look similar to:
Mar 23 04:33:20 dl585 scsi: [ID 243001 kern.warning] WARNING: /scsi_vhci (scsi_vhci0):
Mar 23 04:33:20 dl585 /scsi_vhci/disk@g2000001862b56107 (sd33): Command Timeout on path fp4/disk@w2200001862b56107,0
I have played with setting various kernel parameters such as the following with no improvement.
* sd_io_time
* zfs_vdev_max_pending
* sd_max_throttle
Most of the changes were visible in iostat, but still caused the timeouts. I thought the timeouts only started yesterday, but I see from /var/adm/messages that they have been going back at least a week, showing up here and there. When this happens, the machine effectively freezes for up to a minute then the timeout clears and things start back up again.
The following dtrace program (which I grabbed off the interweb; not sure from where) shows a retry when the machine stops, which corresponds to 100% busy of one or more disks for about 60 seconds.
#!/usr/sbin/dtrace -s
#pragma D option quiet
dtrace:::BEGIN
printf("Tracing... output every 10 seconds.\n");
fbt::sd_set_retry_bp:entry
@[xlate <devinfo_t *>(args[1])->dev_statname,
xlate <devinfo_t *>(args[1])->dev_major,
xlate <devinfo_t *>(args[1])->dev_minor] = count();
tick-10sec
printf("\n%Y:\n", walltimestamp);
printf("%28s %-3s,%-4s %s\n", "DEVICE", "MAJ", "MIN", "RETRIES");
printa("%28s %-03d,%-4d %@d\n", @);
trunc(@);
The machine is a HP DL585 G2 with 24GB of RAM. The i/o is fibre channel from 2x Qlogic 2342 dual port 2gb HBAs (4x 2gb ports). The HBAs feed a Silkworm 3200 and 3250, which in turn connect to two A5200 arrays each in split loop mode (8x 1gb loops). The arrays house 44 total disks roughly split between 15k and 10k spindles.
I do not recall seeing this on a previous v40z server which was replaced three weeks ago with the DL585. It almost seems like the server is overwhelming the arrays but I cannot confirm why or how to stop it.
Does anyone have any suggestions on how to fix this or how to troubleshoot it further?
Thanks,
MartyI know this is an old thread, but there is precious little information out there, so maybe this will help the next guy. After studying mode page settings, it seems that ARRE and AWRE set to one have reduced (but not eliminated) the timeouts. I have played with a LOT of settings. After globally setting the values as described below, the timeouts have been reduced. Prior to setting the values, the drives were a mixed bag of values.
bash-4.1$ for d in /dev/rdsk/c0t2*d0; do sudo sdparm -S -s AWRE=1 $d; done
bash-4.1$ for d in /dev/rdsk/c0t2*d0; do sudo sdparm -S -s ARRE=1 $d; done
If anyone else knows of good ways to reduce these timeouts (on drives that otherwise appear OK), please speak up.
Thanks,

SYSAUX tablespace resize/shrink
Hi All,
I'm using 11g SE on Linux, and SYSAUX tablespace has grown too large (32Gb). I've reclaimed a space and the question is Is there any chance to resize this tablespace back to small size (let's say to 5Gb)?
I'll appreciate any help.
Thank you.Hi,
Here it is an output. I've removed some stuff to fit the message limit.

Please help.

Can I have automatic e-mail setting for ADDM and AWR reports??
Can I have Automatic e-mail settings for all my AWR and ADDM reports so I don;t have to run the reports all the time but they can be sent over to my mailbox and I can review them, if at all I can do that then can I bound them to a particular time frame where I can recieve only those reports durin the peak usage of my database.
thanksHi Rohan,
Can I have Automatic e-mail settings for all my AWR and ADDM reports so I don;t have to run the reports all the time but they can be sent over to my mailbox and I can review them,You bet! I do it for all of my databases:
1 - Use a cron (or preferably dbms_scheduler) to schedule the awrrpt.sql execution, directing the report to a fixed file location (e.g. /tmp).
2 - As step 2 from the scheduled task, direct the report as input to sendmail:
For Windows:
http://www.dba-oracle.com/t_e_mail_interface_windows.htm
For Linux:
http://www.dba-oracle.com/t_email_mailing_messages_plsql.htm
For complete details of job scheduling, see Dr. Hall's book "Oracle Job Scheduling":
http://www.rampant-books.com/book_2005_1_scheduling.htm
Hope this helps. . . .

Hi There,
We're just trying to generate a awr report for one of our databases and the report is coming out with no data.

Thanks

Hi,
I have some questions related to AWR:
1) In AWR there is a section on "SQL ordered by Sharable Memory" . I am not clear what is the meaning of sqls ordered by sharable memory? and and how that information could be used for a tuning oppertunity?
2) in the SQL Statistics section of AWR, several sqls are listed under each group (e.g. for sqls ordered by elapsed time, ordered by cpu time etc). Is there a rule that how many sqls will be listed there? I mean say under teh sqls ordered by elapse time category how many sql statements will be listed? In one AWR report I found 16 statements under this category. Now in same AWR report, under "SQL ordered by Reads" category I found 10 statements listed (not 16). So what is the rule? How many statements will be listed by Oracle in the AWR for each of the category?
3) Under "instance activity" section lots of stats are given. Are these stats cumulative since the database startup or they are for the snapshot period for which the AWR report is taken? -I think that the stats should be for the snapshot period, not cumulative but want to confirm if my understanding is correct.
ThanksWhat i belive about the query tuning i always start from using Bind Variables.
But if your query is very resource intensive try writing the query in some other manner .
Is your query is using view also if yes check the view if it is meargable or non mergable.
Try to investigate your execution plan for the query and. tune it.
As far as a full table scan is concerned it depends on the selectivity part of your sql query
if the sql is returning high numbers of rows then . it is optimal way to do the operation by
a full table scan.
the best way to tune your sql is to generate the plan output from the trace file of the session
by using the tkprof utility.
sql> alter session set sql_trace=true;
sql>------------do your work...
sql> alter session set sql_trace=false;
then a trace file will be generated in to your udump folder...
which can be analysed for getting the sql execution plan which oracle used
to solve the result.....
Try it if you find some difficulty let me know...
i will help you.

here intresting is that i also can't have the memory section view also.i trien to clear awr repositary and recreate it..bounce database,also tried taking different snap value.But does notmake any change.can u tell me why tha happening..and how can i get a good awr report.Hi there,
I have covered this in my blog entry on the subject. Check that link out for more licensing information and other resources.
The problem you are experiencing is caused by the fact that AWR is part of the DIAGNOSTIC and TUNING packs of Oracle 11g, which as of 11g is no longer a standard feature of the database but rather an optional extra which must be licensed in addition to your default Oracle Standard Edition package. In terms of the licensing, you just need to license it as an optional extra so that you will actually be using it legally, and then you can go ahead and enable it.
While it may be an additional licensed item, it is actually installed on your DB by default, but is just not enabled. So, once you have cleared the licensing issue, you will be free to enable diagnostics by setting the new database parameter, CONTROL_MANAGEMENT_PACK_ACCESS. You can do this by running the following as a dba:
<pre>alter system set control_management_pack_access="DIAGNOSTIC+TUNING" scope=both;</pre>
After running this command, your database will start accumulating diagnostic information. Note that you will need to wait until new snapshots are created in which the new diagnostic information will be available. I found that although most of the information became available after setting CONTROL_MANAGEMENT_PACK_ACCESS, it was only once the database was restarted that all of the information became available. I have seen many people reporting similar behavior.
Old snapshots will obviously continue to give the errors because they did not have the diagnostic information available at the time. -
What are the side effects of setting "_object_statistics=false"?
Hi,
On a 10.2.0.3.0, due to frequent ORA-04031 errors, we have been recommended to set objectstatistics=false in init.ora and bounce the database.
Metalink Bug ID: 3519807
Going through the available documentation on net, I found that this parameter would have same effect as setting STATISTICS_LEVEL=BASIC or even worse.
Documentation (for statistics_level) says following options are affected.
* Automatic Workload Repository (AWR) Snapshots
* Automatic Database Diagnostic Monitor (ADDM)
* All server-generated alerts
* Automatic SGA Memory Management
* Automatic optimizer statistics collection
* Object level statistics
* End to End Application Tracing (V$CLIENT_STATS)
* Database time distribution statistics (V$SESS_TIME_MODEL and V$SYS_TIME_MODEL)
* Service level statistics
* Buffer cache advisory
* MTTR advisory
* Shared pool sizing advisory
* Segment level statistics
* PGA Target advisory
* Timed statistics
* Monitoring of statistics
We have daily schema statistics gathering schedule in place so I feel query performance should not be affected (of course, this is my assumption).
I just wanted to know what else would be affected due to this.
Thanks in advance.
Regards,Please let me know your ideas/inputs.

Need help in reviewing AWR report
Hello Friends,
I need some information on reviewing this AWR report. Can you please tell me if you see any red flags or out of the ordinary? I’m trying to look for some performance or blocking issue that may be causing a process to run for longer than expected time or eventually terminate without finishing.
C:\Users\SIDDHARTH\Documents\Desktop\awr_rpt_-wbprdsnap_193927_thru_193952.htm
I do appreciate your help.
Thank you,Hi Ehtiram,
Thanks for your suggestion.
I have enclosed SQL stat rpt. can you suggest me which SQL ID causing this issue.

How to generate AWR report by using ttStats?
Hi all,are there any links or documents to show how to use ttStats toolkit to generate a report like Oracle AWR report?
If no links or document available, could you tell me how to use it?
In fact I want to know how to do a performance analysis for my application and perform some tune.
If any other toolkits are more suitable please let me know and of course the guide that how to use them is much welcome.
Thanks.The ttStats executable can be found in the <TimesTen_home>/support directory. Before you can run the executable within a command prompt, you'll need to source the ttenv.* file in the <TimesTen_home>/bin directory.
The output of ttStats -h is as follows:
ttStats [-latchstats on|off] [-display-options] [-xml file]
[-statlevel level] <dsn or connstr>
ttStats -s[napshot] [-latchstats on|off] -xml <file> <dsn or connstr>
ttStats -report <xmlfile1> <xmlfile2> <-text|-html> <report_file>
Where parameters in <> are required, and in [] are optional.
-display-options:
This option only works in monitoring mode as
screen filtering. ttStats only displays on the
screen statistics with specified prefixes.
Available prefix options include:
-cg, -ckpt, -conn, -db, -grid, -lock, -log, -repl,
-stmt, -txn, -xla, -zz, where the naming of prefixes
conforms to naming of statistics in TimesTen
sys.systemstats table. If no display option
is specified, all statistics are displayed
by default. For example, run command
ttStats -cg -stmt dsn=TptbmData
to display only cache group and statement
related statistics.
-h[elp] Print help message and exit.
-interval <secs> Collect a set of statistics every <secs> seconds
(default=10).
Note: setting this lower can negatively impact
performance
-xml <file> Write statistics to <file> in XML format. All
statistics will be written to <file> no matter
whether they are displayed on screen or not.
For example ttStats -xml mon.xml dsn=TptbmData
and ttStats -xml mon.xml -cg dsn=TptbmData
write the same file even if the latter only
shows cache related statistics on the screen.
-snapshot One snapshot of all statistics are saved to disk
in the specified file format, then the program
exits. This option should be used together with
the -xml option.
-statlevel <level>
Set the SysStats level, this value of level only
applies to sys.systemstats table.
-report <xmlfile1> <xmlfile2> <-xml|-text|-html> <report_file>
Compare two snapshots, and generate an AWR like
report. At present, each XML file contains only
one snapshot. The difference is computed as the
absolute value of statistic value in <xmlfile2>
minus that in <xmlfile1>. The result can be
written in HTML and plain text formats. XML is
not supported as output format at present.
As an example, you can run the utility as the instance admin user by doing something like:
./ttStats -s -xml tmp.xml <DSN>
You can then open tmp.xml with a web browser and see statistics about the database.
You can also compare two previously captured snaps by doing something like:
./ttStats -report tmp1.xml tmp2.xml -html tmpReport.html -
Shell script for Automatic Awr Report
Hi Good Morning,
I have a requirement to generate the AWR report daily between (10AM - 06PM , 10AM - 01PM , 01PM - 10PM) . I have the below script for this . But the issue is this script is working only when i run it two times and before running i have to delete snap_list.lst file.

"Alter system set command" in a RAC database!!
Hi, all.
The database is (10.2.0.2.0) 2- node RAC database on 32-bit windows 2003
EE SP1.
I issued the following command on Node 1 database.
--> Alter system set db_block_buffers= xxx sid='rac1';
I was able to see "PE enqueue" in top 5 wait event section from an AWR report.
In addition, I was able to find "PZ99","PZ98" process dump file in BDUMP.
Soon later, I could find CKPT and DBWR hung.
Is there anyone who experienced this issue?
Thanks and Regards.

You check sequence cache. If it has less value, increase it to 10000.
select CACHE_SIZE from dba_sequences where SEQUENCE_OWNER='SYS' and SEQUENCE_NAME='AUDSES$';
SQL> alter sequence sys.audses$ cache 10000;

User I/O and db file parallel read is high in AWR report
Hi,
We have one performance issue during a job execution.
From the awr report we have identified one query with a table having millions of records causing problems and then we had also fine tuned that query by changing it's code and by using the optmizer hints. It is being executed in plsql batches. After fine tuning, On the first batch execution(first 5000 records) the query is taking only 5 mins, but on the consecutive batches it is consuming more time( more than 30 mins).
From the awr report I got the statistics as
Release : 11.2.0.2.0
Instance Efficiency Percentages (Target 100%)
Buffer Nowait %: 100.00 Redo NoWait %: 100.00
Buffer Hit %: 85.44 In-memory Sort %: 99.98
Library Hit %: 99.76 Soft Parse %: 99.15
Execute to Parse %: 88.91 Latch Hit %: 100.00
Parse CPU to Parse Elapsd %: 87.32 % Non-Parse CPU: 98.65
The buffer hit % is good. On each batch execution it is taking different set of records.
Top 5 Timed Foreground Events
Event Waits Time(s) Avg wait (ms) % DB time Wait Class
db file parallel read 120,485 42,540 353 89.60 User I/O
DB CPU 3,794 7.99
db file sequential read 145,074 606 4 1.28 User I/O
db file scattered read 70,030 556 8 1.17 User I/O
direct path write temp 12,423 21 2 0.04 User I/O
So the I/O is our main concern since that query contains one table with millions of records.
Host CPU (CPUs: 24 Cores: 24 Sockets: 4)
Load Average Begin Load Average End %User %System %WIO %Idle
1.40 1.45 0.6 0.3 3.7 99.0
Load is also normal.
From the Time model statistics , sql execute elapsed time is 98.27% of db time and only 7.99% is that of DB CPU.
Memory Statistics
Begin End
Host Mem (MB): 64,318.0 64,318.0
SGA use (MB): 30,720.0 30,720.0
PGA use (MB): 488.2 497.1
% Host Mem used for SGA+PGA: 48.52 48.54
Both the size of sga_max_size and sga_target are 32,212,254,720(32gb) bytes and that of
pga_aggregate target is 629,145,600(600mb)
from this it is evident that the memory is still available(so increase in memory size is not an option).
The sql statistics for that query shows like that
Elapsed Time (s) Executions Elapsed Time per Exec (s) %Total %CPU %IO SQL Id SQL Text
44,950.03 55 817.27 94.67 6.99 94.72 79dgmrxh4kv74 SELECT /*+ index(cdr_data cdr_...
I can't understand whether the problem is in the database side or with the query?
If the problem is with the query, then how it has been executed in 5 mins for the first batch ?
(all the batches are having 5000 records each).
And how can we reduce the db file parallel read ?
Your valuable advice will be greatly appreciated.
Thanks in advance
Manoj Kumar N"db file parallel read" is likely to be associated with something like index prefetching.

Tune the SQL.
Review the execution plan.
Check whether the statistics are accurate.
Review whether the index hint (and others that we can't see) is appropriate.
