DBWR_IO_SLAVES について
ORACLE:11.2.0.3 OS:Linux
DBWR_IO_SLAVESについて調べていて、下記のような記述を見つけたのですが
あまり理解出来ていません。
DBWR_IO_SLAVESを設定すると、DBWRに対し設定した数のI/O SLAVEが起動されます。I/O SLAVEはDISK I/OのみをDBWRと並行に行います。
BUFFERのFLUSHなどのDBWRとしての動作は、DBWR本体が行います。
DBWR_IO_SLAVES を設定すると、DBWRは1つしか起動されません。 DBWRのI/Oスレーブプロセスが複数起動されます。
DB_WRITER_PROCESSES と DBWR_IO_SLAVES を同時に指定するとDBWR_IO_SLAVES の値が優先されます。
Q1.そもそもI/O SLAVEとはなんでしょうか？非同期I/Oという記述もあったのですがこちらも意味が分かりません。
Q2.「BUFFERのFLUSHなどのDBWRとして～」という記述について
結局はDBWR_IO_SLAVESを設定してもしなくてもDBライターの動きは同じなのでしょうか？
Q3.DBWR_IO_SLAVESを設定するメリットは何になるでしょうか？
「非同期I/O」という意味が理解出来ていないので、噛み砕いた表現をして頂けると嬉しいです。。。
宜しくお願い致します。
Q1.そもそもI/O SLAVEとはなんでしょうか？非同期I/Oという記述もあったのですがこちらも意味が分かりません。非同期I/Oの技術的な説明はこちらが良いですかね。。
<<http://lab.klab.org/files/alm/20070806/aio.pdf>>
I/O SLAVEはアプリケーションから渡されたDISK I/OをDBWRが一つのプロセス上で全て処理するのではなく、それぞれのI/O SLAVEに渡す事で、アプリケーション側からはDBWRはあたかも並列で非同期にI/Oを処理しているかのように見せる技術と理解してます。
Q2.「BUFFERのFLUSHなどのDBWRとして～」という記述について
結局はDBWR_IO_SLAVESを設定してもしなくてもDBライターの動きは同じなのでしょうか？DISK I/OのみをSLAVEに実行させる、とあります。
BUFFERのFLUSH処理等は設定していてもしていなくても変わらないが、DISK I/Oの動作はSLAVE経由になるので変わる、という理解です。
Q3.DBWR_IO_SLAVESを設定するメリットは何になるでしょうか？非同期I/Oが使えない環境において、DBWRのDISK I/O処理がボトルネックになっている場合に、DISK I/O処理を分散させる事でそのボトルネックを解消する事ができると考えてます。
基本的に11.2.0.3が入るLinuxであれば、libaioが入っていると思いますので、非同期I/Oが可能だと考えてます。

Checkpoint not complete + db_writer_processes/dbwr_io_slaves
Hi,
Oracle Database 11g Release 11.1.0.6.0 - 64bit Production With the Real Application Clusters option.
After I noticed this error into the alert log:
Thread 2 cannot allocate new log, sequence 152831
Checkpoint not complete
Current log# 17 seq# 152830 mem# 0: +ONLINELOG/evodb/onlinelog/group_17.272.729333887
Thread 2 advanced to log sequence 152831
Current log# 14 seq# 152831 mem# 0: +ONLINELOG/evodb/onlinelog/group_14.269.729333871
And read a lot to understand the real cause (for the moment I increased the the redolog file from 5 to 7 (250mb each)).
As it seems I've no problem with the ARCH processes, I read that the cause can be the DBWR0 process that is not "fast" enough to write block I've into redos, and free them for archiving.
I read then something about the asynchronous I/O, and how db_writer_processes/dbwr_io_slaves can simulate the async write to disk.
I think I understood the difference between db_writer_processes and dbwr_io_slaves.
My question is how I can understand if my database needs more DBWR process.
At the moment my configuration is:
db_writer_processes 1
dbwr_io_slaves 0
Thanks in advance,
SamuelHi Samuel,
There is still a major confusion on your side concerning the DBWR. It will NOT write data from your redo buffers to the redo logs, since it is the job of the LGWR.
When a log switch occurs (so, you will use a different redo group), then it is the job of the ARCn process(es) to backup the 'used' redo log to a archive log.
When your ARCn process(es) are not fast enough, and a log swicth occurs, it may happen that you have no inactive (read archived) redo group.... then Oracle 'hangs' till it can find such a redo group available.
So, you may want to add 1 (or more) redo group, or increase the size of the redo log files, or have more archiver processes.
DBWr job is to write dirty database blocks back to datafiles.
CKPT also works independently of the LGWR and DBWR.

ORACLE8에서의 DBWR (DBWR_IO_SLAVES와 DB_WRITER_PROCESSES)
제품 : ORACLE SERVER
작성날짜 : 2002-08-12
Oracle 8에서의 DBWR (dbwr_io_slaves와 db_writer_processes)
Oracle 7에서의 db_writers는 master-slave processing을 통해, async I/O를
simulate하기 위해 사용되었다고 볼 수 있다. Oracle 8에서 DBWR의 write
processing에 더 나은 성능을 제공하기 위해 복수 개의 database writer를 사용
하는 방법은 다음과 같이 두가지로 나눌 수 있다.
1. DBWR IO slaves (dbwr_io_slaves)
Oracle7에서의 mulitple DBWR process들은 단순히 slave process로서, asynch
I/O call을 수행할 수는 없었다. Oracle 8.0.3부터, slave database writer code
가 kernal에 포함되었고, slave process의 async I/O가 가능하게 되었다. 이것은
init.ora file 내에 dbwr_io_slaves라는 parameter를 통해 가능하며, IO slave가
asynchronous I/O가 가능하여 I/O call 이후에 slave가 block되지 않아 더 나은
성능을 제공한다는 것을 제외하고는 Oracle7과 매우 유사하다. slave process는
instance 생성 시기가 아닌 database open 시에 start되기 때문에 oracle process
id가 9번부터 할당되며, o/s에서 확인되는 process 이름도 ora_i10n_SID와 같은
형태가 된다.
dbwr_io_slaves=3으로 지정한 경우, 아래와 같은 oracle background process가
구동되며, ora_i101_V804, ora_i102_V804, ora_i103_V804이 dbwr의 slave
process들이다.
tcsol2% ps -ef | grep V804
usupport 5419 1 0 06:23:53 ? 0:00 ora_pmon_V804
usupport 5429 1 1 06:23:53 ? 0:00 ora_smon_V804
usupport 5421 1 0 06:23:53 ? 0:00 ora_dbw0_V804
usupport 5433 1 0 06:23:56 ? 0:00 ora_i101_V804
usupport 5423 1 0 06:23:53 ? 0:00 ora_arch_V804
usupport 5431 1 0 06:23:53 ? 0:00 ora_reco_V804
usupport 5435 1 0 06:23:56 ? 0:00 ora_i102_V804
usupport 5437 1 0 06:23:56 ? 0:00 ora_i103_V804
usupport 5425 1 0 06:23:53 ? 0:00 ora_lgwr_V804
usupport 5427 1 0 06:23:53 ? 0:00 ora_ckpt_V804
2. Multiple DBWR (db_writer_processes)
multiple database writer는 init.ora file내의 db_writer_processes라는
parameter에 의해 구현되며, 이것은 Oracle 8.0.4부터 제공되었다. 이것은
기존의 master-slave 관계가 아닌 진정한 의미의 복수개의 database writer를
사용하는 것이며, database writer process들은 PMON이 start된 후에 start되어
진다.
이름은 ora_dbwn_SID 형태이며, 아래에 db_block_lru_latches=2,
db_writer_processes=2로 지정한 경우 구동된 oracle background process들의
예이다. 여기에서 ora_dbw0_V804, dbw1_V804이 dbwr process들이다. 만약
db_writer_processes를 지정하지 않으면 기본값은 1인데 이 때도 Oracle7과 같이
ora_dbwr_SID 형태가 아닌 ora_dbw0_SID 형태의 process가 구동된다.
usupport 5522 1 0 06:31:39 ? 0:00 ora_dbw1_V804
usupport 5524 1 0 06:31:39 ? 0:00 ora_arch_V804
usupport 5532 1 0 06:31:39 ? 0:00 ora_reco_V804
usupport 5528 1 0 06:31:39 ? 0:00 ora_ckpt_V804
usupport 5530 1 0 06:31:39 ? 0:00 ora_smon_V804
usupport 5526 1 0 06:31:39 ? 0:00 ora_lgwr_V804
usupport 5520 1 0 06:31:39 ? 0:00 ora_dbw0_V804
usupport 5518 1 0 06:31:38 ? 0:00 ora_pmon_V804
db_writer_processes로 지정된 각 writer process는 하나의 latch set에 할당된다.
그러므로 db_writer_processes를 db_block_lru_latches으로 지정되는 LRU latch의
갯수와 같은 값으로 지정하는 것이 권장할 만하며, 단 CPU의 갯수를 초과하는 것은
바람직하지 않다.
[참고] 현재까지 init.ora file내에 구동되는 dbwr의 갯수는 db_block_lru_latches
parameter에 의해 제한된다. 즉 db_writer_processes 값을 db_block_lru_latches
보다 크게 하여도 db_block_lru_latches로 지정
된 수의 dbwr process가 기동된다.
Oracle8에서 DBWR I/O slave나 복수개의 DBWR를 제공하는 방법 중 좋은 점은
이 기법을 제공하는 것이 kernal 안에 포함되어 기존의 OSD layer로 구현되었던
것보다 port specific한 부분이 없고 generic하다는 것이다.
3. 두 가지 방법 중 선택 시 고려사항
이러한 두가지 형태의 DBWR 기법이 모두 도움이 되기는 하지만, 일반적으로
어느 것을 사용할 것인지는 OS level에서 asynchronous I/O가 제공하는지와
CPU 갯수에 의존한다. 즉, system이 복수 개의 CPU를 가지고 있으면
db_writer_processes를 사용하는 것이 바람직하며, aync I/O를 제공하는 경우
두 가지 모두 사용에 효과를 얻을 수 있다. 그런데 여기서 주의할 것은
dbwr_io_slaves가 약간의 overhead가 있다는 것이다.
slave IO process를 가능하게 하면, IO buffer와 request queue의 할당을 위해
부가적인 shared memory가 필요하다.
multiple writer processes와 IO slave는 매우 부하가 많은 OLTP 환경에서
적합하며, 일정 수준 이상의 성능을 요구할 때만 사용하도록 한다. 예를 들어
asynch I/O가 사용 가능한 경우, I/O slave도 사용하지 않고 하나의 DBWR만을
asynch I/O mode로 사용하는 것이 충분하고 바람직할 수 있다. 현재의 성능을
조사하고 bottleneck이 되는 부분이 DBWR 부분인지 정확히 조사한 후 사용하여야
한다.
[참고] 이 두 parameter를 함께 사용하면 dbwr_io_slaves만 효과가 있다.
이것은 dbwr_io_slaves는 master dbwr process를 db_writer_proceses에 관계 없이
하나만 가지도록 되어 있기 때문이다.http://www.fors.com/velpuri2/PERFORMANCE/ASYNC

Dbwr_io_slaves or db_writer_processes
Im having a little trouble understanding the situations in which using dbwr_io_slaves would be better than db_writer_processes, it would be nice if someone could explain it clearly or point me to documentation that explains it cleary.
I have a secondary question which im pretty sure is related, which is, one of the databases that I deal with has a large number of dirty buffers (ie: > 600,000) at the moment the only way I know to clear this and reduce the number is to restart the database from time to time (this is not something I want to be doing and need a better solution).
Some background information:
The database gets information loaded into it in batches on a nightly basis, the server the database runs on has two dual core cpu's with 8gb of ram, there are also a couple of other databases running on these systems as well.With DBWR I/O Slaves, you have one dbwr processes that gathers dirty blocks from the cache and shares them out to the I/O slaves to write. This emulates asynchronous I/O for operating systems that don't have it, and probably isn't needed on any modern system.
With multiple database writers you break the cache into smaller pieces (working data sets) and each DBWn is responsible for keeping part of the cache clean - this improves scalability for extreme cases but if you read Kevin Closson's blog (The index http://kevinclosson.wordpress.com/kevin-closson-index/general-performance-and-io-topics/ has a number of posts on over-configuring dbwr processes) you will see why this isn't often necessary.
Your 600,000 dirty blocks is a big number - how big is the entire buffer cache, and how are you checking that number ? One possibility for the size is that consistent read copies of dirty current blocks don't seem to get their dirty bit cleared on some versions of Oracle. If you refine you test to show the block state, you may find that most of the dirty blocks are CR copies.

Db_writer_processes vs dbwr_io_slaves
Hi All
Could please let me know how these two parameters can be used efficiently
we have our DB on Unix Oracle 8,9, 10
thanx
KedarNot meaning to be condescending, but if you have a system that needs this sort of tuning then I think you need to take a slightly more 'scientific' approach (And please lets's not turn this into another argument about the use of the term scientific in regards to Oracle!) as well as get thoroughly acquainted with the documentation (Concepts guide if you need it, then the tuning guide).

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 ,

Database Initialization Parameters for Oracle Applications 11i
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=216205.1 -
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
Tanmai -
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.

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.
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.

As you can see, I have deleted what was in here (and then run a crosscheck), so I could actually do anything, since the disk was full. -
Check point not completed in oracle 8i
Hi,
in alert log file i found the error like:
Thread 1 cannot allocate new log, sequence 216998
Checkpoint not complete
Current log# 5 seq# 216997 mem# 0: /oracle5/oradata/metasolv/redo05.log
Current log# 5 seq# 216997 mem# 1: /oracle2/oradata/metasolv/redo05a.log
Wed May 7 17:21:01 2008
Thread 1 advanced to log sequence 216998
it appers suddenly in alert log file and database users are complaining that database is very very slow and not able to complete theri task in database and lot of archive log are generating in archive destanation, what will be the exact cause.
Regards

Hello. I set up a new dataguard and am receiving errors when I try to start it on my primary. I looked at support note 172779.1 and it says the DB_UNIQUE_NAME needs to match from the log_archive_dest_2 to the db_unique_name of the standby. I think it looks okay but I'm missing something.
