V$DB_CACHE_ADVICE
HI,
I have this doubt , what we will get from this view and how it will help us to tune the size of DBBC sizing .
Iam digging into this for long time but i cant , please help some one.
Thanks,

Question regarding v$db_cache_advice
Hi DBA's
In v$db_cache_advice may I know what is the unit of measure of ESTD_PHYSICAL_READ_TIME? is it in Second? Minute?

Getting ORA- 4031 when switching db_cache_advice to ready stat
i m getting memory allocation error while switching from off to ready...tell me what should i do to make it on.
Check out http://metalink.oracle.com and search with "ORA-04031 DB_CACHE_ADVICE". Several useful documents are found.

Hi,
i was giving a read to the performance guide doc. where i read that v$db_cache_advise views is populated when we set db_cache_advise parameter to on.it seems ok to me till now,but then next it says 'This view shows the estimated miss rates for twenty potential buffer cache sizes, ranging from 10% of the current size to 200% of the
current size. Each of the twenty potential cache sizes has its own row in this view".i am bit confuse with these lines.may i have simple description of these lines so that i able to gulp it completly.
thanks ...826854 wrote:

Help needed for hash_area_size setting for Datawarehouse environment
We have an Oracle 10g Datawarehousing environment , running on 3 - node RAC
with 16 GB RAM & 4 CPUs each and roughly we have 200 users and night jobs running on this D/W .
We find that query performance of all ETL Processes & joins are quite slow .
How much should we increase the value of hash_area_size parameter for this Datawarehouse environment ? This is a Production database, with Oracle Database 10g Enterprise Edition Release 10.1.0.5.0.
We use OWB 10g Tool for this D/W and we need to change the hash_area_size to increase the performance of the ETL Processes.
This is the Oracle init parameter settings used, as shown below : -
Kindly suggest ,
Thanks & best regards ,

Hi everybody!
I have a problem. Some weeks ago I opened a post related to this issue. We have two dataguards with dataguard broker. One of them is resync (thanks to mseberg and this forum) and now I have problems with the other.
Once I have learned how to configure and start/stop dataguard broker, I have a more basic problem, which is to resync it. I follow a process, where I backup the primary with RMAN, I copy the rman files to the other server with the controlfile, at once, I recover with rman again.
The problem is that it is too big, 2 hours for backing it up more or less, and when I restore it, no archivelog list appears being syncronized.
I have followed the same process than the other one and I can't resync it. I think there is something at my params or something new at 11g version...

### PHASE 2: User inputs
Upgrade phase started at Wed Oct 18 21:22:19 2006
Processing Metadata File: upg/common/inputchk/inputchk.met Running upg/common/inputchk/inputchk.pl ### Verify that the database has been backed up
Step started at Wed Oct 18 21:22:19 2006
Before beginning the upgrade, it is important that you backup your database.
Have you backed up your database (y/n)? [y]: y
Ask user for schema and database details
Enter the name of schema that you would like to upgrade [PORTAL]: portal
Enter the password for the schema that you would like to upgrade [portal]:
Enter the password for the SYS user of your database [CHANGE_ON_INSTALL]:
Enter the TNS connect string to connect to the database [ORCL]: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=portaldb.bizmatch.com.cn)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=IASDB.bizmatch.com.cn)))
Responses to the above questions will now be recorded in the file
upgrade.in. Placeholders are recorded instead of actual passwords,
for security reasons. If you wish, this file can be edited and used
as the standard input for a subsequent run of upgrade.pl.
### Verify database connection information.

Pre-Check Completed at Wed Oct 18 21:22:32 2006Hi,
Its good that u pasted the complete log file. In your environment you have to run this upgrade tool only once from any of the middle tier.
And with respect to your error that u got in precheck is quite simple. All u have to do is just run this script from by connecting to portal schema using sqlplus.
Run dropupg.sql
Location-------- /raid/product/OraHome_1/upgrade/temp/portal/prechktmp/dropupg.sql
Later you re-run the upgrade tool and let me know the status.
Good luck

Oracle Connection Pool failure in COM+
I am having some trouble trying to get a specific database to work with an application that makes use of a COM+ Application. When we point the application at the UAT database everything seems fine, but when we point it to the production database after a few successful calls it ends up failing at the COM+ application recycles. The event viewer provides the following information:

Not being an expert in Oracle, I have been able to dig up a little bit of information that might be of use ...
a) Our tnsnames.ora indicates that the connections are to be DEDICATED and running Toad bares this out -- dllhost ends up with a single connection.
b) most of the database initial set of parameters seem to be very similar. The only difference I noticed was that the archive log mode and db_cache_advice are ON for production.
c) We have little control over how the connection strings are being created internally in this COM+ application, but however they are created it works for UAT and doesn't for PROD.
d) When we go into our web application and hit a page that makes use of the COM+ component to render, it will work the first time but when I do a simple browser refresh it will usually fail on the 2nd or 3rd time. Almost like it is trying to expand the connection pool size and the oracle server is throwing up.
If I didn't mention earlier the two database instances run on different servers but the application server is exactly the same. We only change the alias we are using for the database (both are defined in tnsnames) and the password used to make its connection.
Does anyone have any clues on this one? I am really spinning my wheels trying to figure out what could cause this type of situation. Anything at all would be very helpful.It appeared to us that the problem was with the Oracle server and that it might have been failing when we were trying to expand our application connection pool size or basically obtain more connections.
The biggest indicator of this is that we run the same application code against two different databases and one works and one does not work. Having said this, I suppose the problem could be rooted in a data error instead of an oracle server error ...
Is there a specific trace file on the oracle server that would help me point to any error that is truly an oracle server error? Sorry I am very new to Oracle. -

4 Recommendations:
Your database has relatively high logical I/O at 42,976 reads per second. Logical Reads includes data block reads from both memory and disk. High LIO is sometimes associated with high CPU activity. CPU bottlenecks occur when the CPU run queue exceeds the number of CPUs on the database server, and this can be seen by looking at the "r" column in the vmstat UNIX/Linux utility or within the Windows performance manager. Consider tuning your application to reduce unnecessary data buffer touches (SQL Tuning or PL/SQL bulking), using faster CPUs or adding more CPUs to your system.
You are performing more than 15,666 disk reads per second. High disk latency can be caused by too-few physical disk spindles. Compare your read times across multiple datafiles to see which datafiles are slower than others. Disk read times may be improved if contention is reduced on the datafile, even though read times may be high due to the file residing on a slow disk. You should identify whether the SQL accessing the file can be tuned, as well as the underlying characteristics of the hardware devices.
Check your average disk read speed later in this report and ensure that it is under 7ms. Assuming that the SQL is optimized, the only remaining solutions are the addition of RAM for the data buffers or a switch to solid state disks. Give careful consideration these tablespaces with high read I/O: TS_CCPS, TS_OTHERS, TS_AC_POSTED03, TS_RATING, TS_GP.
You have more than 1,222 unique SQL statements entering your shared pool, with the resulting overhead of continuous RAM allocation and freeing within the shared pool. A hard parse is expensive because each incoming SQL statement must be re-loaded into the shared pool; with the associated overhead involved in shared pool RAM allocation and memory management. Once loaded, the SQL must then be completely re-checked for syntax & semantics and an executable generated. Excessive hard parsing can occur when your shared_pool_size is too small (and reentrant SQL is paged out) or when you have non-reusable SQL statements without host variables. See the cursor_sharing parameter for an easy way to make SQL reentrant and remember that you should always use host variables in you SQL so that they can be reentrant.
Instance Efficiency
Buffer Hit: 69.13% In-memory Sort: 100%
Library Hit: 96.4% Latch Hit: 99.99%
Memory Usage: 95.04% Memory for SQL: 64.19%
2 Recommendations:
Your Buffer Hit ratio is 69.13%. The buffer hit ratio measures the probability that a data block will be in the buffer cache upon a re-read of the data block. If your database has a large number of frequently referenced table rows (a large working set), then investigate increasing your db_cache_size. For specific recommendations, see the output from the data buffer cache advisory utility (using the v$db_cache_advice utility). Also, a low buffer hit ratio is normal for applications that do not frequently re-read the same data blocks. Moving to SSD will alleviate the need for a large data buffer cache.
Your shared pool maybe filled with non-reusable SQL with 95.04% memory usage. The Oracle shared poolcontains Oracle´s library cache, which is responsible for collecting, parsing, interpreting, and executing all of the SQL statements that go against the Oracle database. You can check the dba_hist_librarycache table in Oracle10g to see your historical library cache RAM usage.

5 Recommendations:
You have high network activity with 390.6 SQL*Net roundtrips to/from client per second, which is a high amount of traffic. Review your application to reduce the number of calls to Oracle by encapsulating data requests into larger pieces (i.e. make a single SQL request to populate all online screen items). In addition, check your application to see if it might benefit from bulk collection by using PL/SQL "forall" or "bulk collect" operators.
You have 3,931.5 consistent gets examination per second. "Consistent gets - examination" is different than regular consistent gets. It is used to read undo blocks for consistent read purposes, but also for the first part of an index read and hash cluster I/O. To reduce logical I/O, you may consider moving your indexes to a large blocksize tablespace. Because index splitting and spawning are controlled at the block level, a larger blocksize will result in a flatter index tree structure.
You have high update activity with 446.0 db block changes per second. The DB block changes are a rough indication of total database work. This statistic indicates (on a per-transaction level) the rate at which buffers are being dirtied and you may want to optimize your database writer (DBWR) process. You can determine which sessions and SQL statements have the highest db block changes by querying the v$session and v$sessatst views.
You have high disk reads with 15,666.7 per second. Reduce disk reads by increasing your data buffer size or speed up your disk read speed by moving to SSD storage. You can monitor your physical disk reads by hour of the day using AWR to see when the database has the highest disk activity.
You have high small table full-table scans, at 81.6 per second. Verify that your KEEP pool is sized properly to cache frequently referenced tables and indexes. Moving frequently-referenced tables and indexes to SSD or theWriteAccelerator will significantly increase the speed of small-table full-table scans.
Buffer Pool Advisory
Current: 3,599,469,418 disk reads
Optimized: 1,207,668,233 disk reads
Improvement: 66.45% fewer
The Oracle buffer cache advisory utility indicates 3,599,469,418 disk reads during the sample interval. Oracle estimates that doubling the data buffer size (by increasing db_cache_size) will reduce disk reads to 1,207,668,233, a 66.45% decrease.

You are not using large blocksizes for your index tablespaces. Oracle research proves that indexes will build flatter tree structures in larger blocksizes.Systemwide Tuning using STATSPACK Reports [ID 228913.1] and http://jonathanlewis.wordpress.com/statspack-examples/ should be useful.

Hello ,
we are currently experiencing heavy I/O problmes perfoming prrof of concept
testig for one of our customers. Our setup is as follows:
HP ProLiant DL380 with 24GB Ram and 8 15k 72GB SAS drives
An HP P400 Raid controller with 256MB cache in RAID0 mode was used.
Win 2k8r2 was installed on c (a physical Drive) and the database on E
(= two physical drives in RAID0 128k Strip Size)
With the remaining 5 drives read and write tests were performed using raid 0 with variing number of drives.
I/O performance, as measured with ATTO Disk benchmark, increased as expected linear with the number of drives used.
We expected to see this increased performance in the database, too and performed the following tests:
- with 3 different tables the full table scan (FTS) (Hint: /*+ FULL (s) NOCACHE (s) */)
- a CTAS statement.
The system was used exclusively for testing.
The used tables:
Table 1: 312 col, 12,248 MB, 11,138,561 rows, avg len 621 bytes
Table 2: 159 col, 4288 MB, 5,441,171 rows, avg len 529 bytes
Table 3: 118 col, 360MB, 820,259 rows, avg len 266 bytes
The FTS has improved as expected. With 5 physical drives in a RAID0, a performance of
420MB/s was achieved.
In the write test on the other hand we were not able to archieve any improvement.
The CTAS statement always works with about 5000 - 6000 BLOCK/s (80MB/s)
But when we tried running several CTAS statements in different sessions, the overall speed increased as expected.
Further tests showed that the write speed seems to depend also on the number of columns. 80MB/s were only
possible with Tables 2 and 3. With Table 1, however only 30MB/s were measured.
Is this maybe just an incorrectly set parameter?
What we already tried:
- change the number of db_writer_processes 4 and then to 8
- Manual configuration of PGA and SGA size
- setting DB_BLOCK_SIZE to 16k
- FILESYSTEMIO_OPTIONS set to setall
- checking that Resource Manager are really disabled
Thanks for any help.

The FTS has improved as expected. With 5 physical drives in a RAID0, a performance of

In the write test on the other hand we were not able to archieve any improvement.
The CTAS statement always works with about 5000 - 6000 BLOCK/s (80MB/s)
But when we tried running several CTAS statements in different sessions, the overall speed increased as expected.
Further tests showed that the write speed seems to depend also on the number of columns. 80MB/s were only
possible with Tables 2 and 3. With Table 1, however only 30MB/s were measured.
If multiple CTAS can produce higher throughput on writes this tells you that it is the production of the data that is the limit, not the writing. Notice in your example that nearly 75% of the time of the CTAS as CPU, not I/O.
The thing about number of columns is that table 1 has exceeded the critical 254 limit - this means Oracle has chained all the rows internally into two pieces; this introduces lots of extra CPU-intensive operations (consistent gets, table access by rowid, heap block compress) so that the CPU time could have gone up significantly, resulting in a lower throughput that you are interpreting as a write problem.
One other thought - if you are currently doing CTAS by "create as select from {real SAP table}" there may be other side effects that you're not going to see. I would do "create test clone of real SAP table", then "create as select from clone" to try and eliminate any such anomalies.

Performance issue possibly due to wrong parameters??
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit.
We have a program that runs every two weeks to process 3million records in our Oracle 10g database. Processing normally takes about 6 hours. With no change to the program (which is a java client program), the processing time has gotten longer and longer over the last few weeks. The processor on the database server was upgraded to iTanium and during this upgrade the databases were striped to fix a read/write issue that occurred due to poor configuration (it wasn't using multiple channels for processing so everything ran super slow) when the server hardware was upgraded. Since the last upgrade to the processor, we've noticed many errors being generated on the server when our program runs (java null reference errors). these errors never occurred before the upgrade. The upgrade was in July. In August we noticed the beginning of a degradation in performance - the process went from 6 hours to 10 hours. This month, it is taking 20 hours. Next month I fear it will be 40 hours.
The program launches multiple sessions that work at once doing an update against the same table. The last time it ran it started at 6AM and by 1PM it was only 11% done. I looked at the session stats and saw the top 5 wait events:
SQL*Net message from client-->
totalwaits=11,997
timewaited=2,070,070
avgwait=172
enq: TX - row lock contention-->
totalwaits=587
timewaited 65,614
avgwait=111
timeouts=180
latch:cache buffers chains-->
totalwaits=933
timewaited=1,815
avgwait=2
db file sequential read-->
totalwaits=1,426
timewaited=1,519
avgwait=1
log file sync-->
totalwaits=1,422
totalwaited=2594
avgwait=2
It looks like all of these values are way too high and I'm wondering what parameters we could change on the database/server side that might improve performance in these areas.
I read that increasing the INITRANS VALUE TO SOMETHING GREATER THAN ONE WOULD HELP WITH THE ROW LOCK CONTENTION AND TIMEOUTS.
I also read that changing DB_CACHE_ADVICE OFF WOULD HELP WITH THE CACHE BUFFER CHAINS ISSUE.
Are these viable solutions? Changing the program is not an option right now. Any help is greatly appreciated.Rakesh jayappa wrote:
Hi,
sorry i am not getting your question, i am guessing your question, you can reduce the log file sync by
COMMIT WRITE BATCH;
COMMIT WRITE IMMEDIATE;
or
The disks or I/O subsystems where the redologs are placed may be too busy.
- Reduce other I/O activity on the disks containing the redo logs, or use dedicated disks.
- Move the redo logs to faster disks or a faster I/O subsystem.
- Move the redolog files from RAID 5 devices. RAID 5 is not efficient for writes.
- Alternate redo logs on different disks to minimize the effect of the archiver on the log writer.
Kind Regards,
Rakesh JayappaMy point is that even if you eliminate it completely you have only eliminated a tiny fraction of the total wait time -- it may look like low hanging fruit, but it's a very small piece of fruit indeed. -
Ora-00604:error occurred at recursive SQL level 1 and Ora-04023
hi all
i am using oracle linux 5.5 and oracle Database 11g R2 while shutingdown the database i am getting
the following errors.
SQL> shutdown immediate;
Ora-00604:error occurred at recursive SQL level 1
Ora-04023: object select count(*) from reg$SQL>plz can anyone help me out?Couple of questions related to this issue:
1.Is there anything in alert log. Post last 50 lines from alert log.
2.Is there any trace / log generated by Oracle ?
3.What is Memory_Target parameter value ?
4.What is value of statistics_level parameter ?
5.Did you perform any failed upgradation ?
6.Are there any invalid objects in database ?
Generally ORA-00604 is related to insufficient size of shared pool. Now, i am googling how to get a proper value of shared pool size ? I got that there is a view v$shared_pool_advice which will tell me the answer of this question. Ok, it means now question is how do i get the proper value of shared pool from v$shared_pool_advice; i mean how do i interpret this v$shared_pool_advice view ?
No problem docs are there to answer this question : (How i got this link ? Open a new page---http://tahiti.oracle.com---selected 11.2 docs--in the left hand sided there is a search text box i entered v$shared_pool_advice and i got couple of links)
http://download.oracle.com/docs/cd/E11882_01/server.112/e17110/dynviews_3037.htm#REFRN30239
I will read these links and now i will query this and DBA_HIST_SHARED_POOL_ADVICE views, interpret the values. Ok, but what about my original question i.e. ORA-00604 and 4023 ? If i am at this stage, understood all the values, it means now i can understand the meaning / sense of resizing of shared pool.
ALTER SYSTEM SET statistics_level=TYPICAL SCOPE=SPFILE;
You can monitor V$SGA_RESIZE_OPS to identify the range of values that Oracle is automatically resizing the DB_CACHE_SIZE and SHARED_POOL_SIZE components to. Then, pick an appropriate minimum value based on the range. There's no "magic formula". But V$SGA_RESIZE_OPS shows the sizes that Oracle has been automatically been resizing the SGA components to. The Buffer Cache Advisory section of the AWR report or V$DB_CACHE_ADVICE, V$SHARED_POOL_ADVICE, V$SGA_TARGET_ADVICE and DBA_HIST_SGA_TARGET_ADVICE are views that provide advisory information as well. Hemant @ SGA_MAX_SIZE and SGA_TARGET how to set minimum for pools
So, these are the baby steps if i ever gets ORA-00604 and ORA-04023 on my test database. Do all these and feel free to post the next doubt, i am sure you will get the correct answer.

Datafile size minor than 4 Gb: is this a bug?
Hi all! I have a tablespace made up by 1 datafile (size = 4 Gb). Oracle 9.2.0.4.0 (on Win2k server) seems incapable of managing this; in fact, I receive ora-04031: unable to allocate 8192 bytes of shared memory but the memory of Oracle is configured correctly. Resizing this tablespace and adding a new datafile so that every datafile is 2 Gb large, I don't receive the error any longer. what do you think about this?
Bye. Ste.Hello everybody;
The Buffer Cache Advisory feature enables and disables statistics gathering for predicting behavior with different cache sizes. The information provided by these statistics can help you size the Database Buffer Cache optimally for a given workload. The Buffer Cache Advisory information is collected and displayed through the V$DB_CACHE_ADVICE view.
The Buffer Cache Advisory is enabled via the DB_CACHE_ADVICE initialization parameter. It is a dynamic parameter, and can be altered using ALTER SYSTEM. Three values (OFF, ON, READY) are available.
DB_CACHE_ADVICE Parameter Values
OFF: Advisory is turned off and the memory for the advisory is not allocated.
ON: Advisory is turned on and both cpu and memory overhead is incurred.
Attempting to set the parameter to the ON state when it is in the OFF state may lead to the following error: ORA-4031 Inability to allocate from the Shared Pool when the parameter is switched to ON. If the parameter is in a READY state it can be set to ON without error because the memory is already allocated.
READY: Advisory is turned off but the memory for the advisory remains allocated. Allocating the memory before the advisory is actually turned on will avoid the risk of ORA-4031. If the parameter is switched to this state from OFF, it is possible that an ORA-4031 will be raised.
Make sure too that you dont need to use RMAN program to make backup...baceuse the large pool is used to this too.
Regards to everybody
