Db_writer_processes value
I have lots of waits for the free buffer waits events.
i need to increase the db_writer_processes parameter.
My disk_asynch_io is set to true.
Architecture:
oracle version: 10.2.0.1
os linux x86:
# cpu: 2 dual core
ram:3gig
# disk: 3: data on disk 1
index on disk 2
archive on disk 3
What value should i increase my db_writer_processes parameter?
as a general rule, you have 1 database writer and as many asynch IO servers as required. You may have other issues which need to be looked at if you are experiencing 'waits'.

BR0978W Database profile alert
Hi,

Please checks it and suggest me.

S.PrasadHello Prasad,
Well the parameter recommendation is depends on the database version and SAP release version.
Using the relevant parameter notes for the affected system (Oracle 9i and lower: Note 124361 and 180605 (BW); Oracle 10g and higher: 830576), check whether the settings (<curr_val>) you are using are actually correct. If so, use transaction DB17 to change the <check_val> test values for the affected parameters to the correct <curr_val> value, to avoid future unjustified warnings. Alternatively, you can also deactivate or delete the checks in DB17 (Active = "N").
If warnings are issued correctly, you must adjust the parameter settings in init<sid>.ora (and, if necessary, the other configuration files included there using IFILE).

DB_WRITER_PROCESSES in Oracle 10.2.0.4 HP UX
Hi all,
I noticed that asynchronous i/o cannot be used with regular filesystem on HP UX (only raw devices).
As far as I know what I can do is to configure multiple db writers with DB_WRITER_PROCESSES parameter.
DB has CPU_COUNT in 16, but 2 db writers (default value = CPU_COUNT / 8).
Will I have any benefit by increasing DB_WRITER_PROCESSES?
Or only if there is a bottleneck in writing dirty buffers?
Thanks>
If bottleneck exists it would be at the disk end & not the CPU end.
Server processes are at least 1000 times faster than mechanical disk drives.
a single DB_WRITER could keep 10 disk controllers busy & not be a bottleneck.Well, then why does Oracle default to 1 process every 8 cpus?
DBWn also handles checkpoints, file open synchronization, and logging of Block Written records, according to [url http://docs.oracle.com/cd/E11882_01/server.112/e25513/bgprocesses.htm#BBBDIIHC]the docs. On hp-ux Oracle does file handles oddly - see MOS How to Disable Asynch_io on HP to Avoid Ioctl Async_config Error Errno = 1 [ID 302801.1] if you (the OP) haven't already.
So on hp-ux you have a potential problem of the architecture assuming asyncronicity but the dickering between dbw, lgwr and ckpt turning into bickering. Just because something is 1000 times faster doesn't mean it isn't doing 1000 more operations. In real life, you wind up with Oracle telling you to ignore Private strand flush not complete errors, because there are no actual lgwr problems unless switches are slow. -
Initial Parameter DB_WRITER_PROCESSES Doesn't work
I set the initial parameter DB_WRITER_PROCESSES as 5 in init.ora file. But when I restarted the database, I found the parameter show as 1 and only DBW0 existed.
I don't know the reason, would you please help me?
Thanks and Best Regards,
Su QianDid you get a message in the alert log about starting dbwr processes failed?No, I havn't gotten the message.
Also, having multiple writers on a single cpu system could bring performance down. I think one rule of thumb is to have 4 cpus per writer.Thanks for your message. I will not re-set the parameter.
First, I'd like to let you know that the environment of my production database are as follows:
OS: HP-UX
Database Version: Oracle8 Enterprise Edition Release 8.0.4.2.1 - Production
The setting of DB Block: 2K
The main problem I come across is when running application the response speed of DB is very slow.
The first step I adopted was checking free space. After checking I thought it was sufficient. But when I adopted the second step checking v$system_event, I found the wait time of following events is high.
EVENT TOTAL_WAITS TOTAL_TIMEOUTS TIME_WAITED AVERAGE_WAIT
db file parallel write 471 1 128370 272.547771
log file parallel write 30307 0 51440 1.69729765 (For reference)

smon timer 372 369 11082933 29792.8306
write complete waits 75 37 5149 68.6533333
According to the above message, I decided to tune I/O first. Is my thought right?
If dbwr is rather slow, these events should give som hints: free buffer waits, rdbms ipc reply, log file switch (checkpoint incomplete).Yes, when I had a look at the alert.log I found the error message: checkpoint incomplete. So I created a new log group.Perhaps the problem was too few log groups and not dbwr. If you do not have high free buffer waits dbwr should be ok :)I agree with you. I havn't high free buffer waits, so the main problem could be too few log groups. But I don't understand two points as follows.
1. Last Friday I had 4 log groups and the size of every group is 2M. when getting the message "Thread 1 cannot allocate new log, sequence 87816 Checkpoint not complete", I created a new log group of 2M. Normally, this operation should improve performance, but when I observed the statistics I found the average wait time of "db file parallel write" became more longer. (Please refer to the following list)
EVENT TOTAL_WAITS TIME_WAITED AVERAGE_WAIT DATE LOG_GROUPS
db file parallel write 471 128370 272.547771 2002-08-05 5
db file parallel write 798 88568 110.987469 2002-08-03 4
2. I think the shortage of log groups is caused by the archive of log group don't complete before overwirting. From the alert.log file I found the time of log switch is about 20 minutes. From my viewpoint 20 minutes is enough for log archive. Why is the log groups still short?
In addition, according to the setting of checkpoint parameters I think the checkpoint should occur only at the time of log switch.

log_checkpoint_timeout integer 0
db_block_max_dirty_target integer 4294967294

Do you know the meaning db_block_checkpoint_batch? (I can't find it in the document of 8i, because it is obsoleted.)
From the alert.log file, I got the following errors.
1. Fri Aug 2 17:10:36 2002

Db_writer_processes alert log message
Oracle 11.2.0.3 running on HP-UX Itanium RX8640 with 16 CPUs and OS B.11.31
Upgraded to 11.2.0.3 last night and now I am receiving the following message in alert.log when starting database:
"NOTE: db_writer_processes has been changed from 4 to 1 due to NUMA requirements"
Any thoughts on what this means?Is your system NUMA-enabled?
In a NUMA-enabled box, the minimum number of DBWR process is the number of processor groups, oracle MUST start this minimum of DBWR no matter the parameter you set.
You seem to have the opposite case, as in oracle is forcing it to 1. In this case, I'm led to believe that maybe oracle is mistakenly identifiying your system as NUMA perphaps.
Upload the results for this:
select a.ksppinm "Parameter",
b.ksppstvl "Session Value",
c.ksppstvl "Instance Value"
from x$ksppi a, x$ksppcv b, x$ksppsv c
where a.indx = b.indx and a.indx = c.indx
and a.ksppinm = '_db_block_numa';You may try to do this:
- Set the following OS variable in your database OS owner user profile: DISABLE_NUMA = true
- Set the DBWR to 4 in the SPFILE and bounce the database.
- Verify if the issue continues. In the OS: ps -ef | grep dbwr to see how many dbwr the instance spawned. -
MAX DB_WRITER_PROCESSES in 10g
Hi All,
I read the doc (Problem statement: [bug# 2441217]) from the metalink on the # of DBWRs. It says that Oracle changed the default # of DBWRs and MAX DBWRs since 9iR2.
Default: (CPU_COUNT + 7) / 8
Max: Min (CPU_COUNT / 2, 20)
Is it right? I tested this on HP
CPU_COUNT = 16, DB_WRITER_PROCESSES = 14
Based on the new algorithm MAX DBWRs are 8. But there are 14 DBWR processes up and running.
I think Oracle uses the privious aloghrithm even in 10g, which is based on dbblock_lru_latches.
Any idea?Hi Sean,
As I understand it, db_block_lru_latches defaults to the following formula :
(CPU_COUNT x 6) or (DB_BLOCK_BUFFERS/50), whichever is less.
In earlier releases it defaulted to CPU_COUNT/2. If you set DB_BLOCK_LRU_LATCHES higher than this max value on systems where it is available (<9i) or set the undocumented parameter DBBLOCK_LRU_LATCHES higher, then Oracle just ignores this and sets it internally to the above calculated value. However it will be set to Num_pools x (CPU_COUNT/2) if multiple buffer pools (default, recycle, keep and any of the multi-block size pools) are setup.
More notes shere:

Hi,
When one of process ran in 11.5.10.2, DBWR0 process get loaded since that process execute INSERT internally. I'm thinking to increase db_writer_processes process to 3. The current parameter value is 1.
Does this help ?
or in what situation we need to have more db_writer_processes processes.
ThanksHi,
Please refer to the following documents for guidelines about setting this parameter.

Well, the parameter can be changed by the alter system but why you want to do it? Why you want to enable more dbwr;s in the first place?
Aman....I want to change the value more than 1 and improve the dbwr efficiency? but I don't know wether can do this. -
Hi All,
Can you please educate me on below things. Also, please correct me if i am wrong
1.
db_writer_processes controls number of db writers that are been started when instance is initialized. So, once DB is up lets say we have 6 dbwriter process then your buffer cache is splitted in 6 working data sets. Can you please explain what is this datasets are ? or may be if i am wrong .
2.
If so this is true how can we find that which dataset is used by which dbwrite processes. I mean how to find one to one mapping for say 0x address- to 0y address is been worked by dbwr1 process and so on. how to find this
3.
If we have multiple buffer cache like db_16k and db_32k then how do we map this.
Reason behind this we are using 12 dbwriter process for we have 12gb of sga and 10gb of pga. Some time we are getting buffer busy waits. So, need to find that we are using multiple buffer pools. So, if it is from there then i can suggest management to use only default block size and not multiple. I already know that multiple buffer pool have overhead of managing one more memory structure so need to investigate and learn from you.
My idea is to reduce this and then start adding processes if necessaryHi Jonathan,
Thank you very much so here are the things which we can conclude from this. Please correct me if i am wrong as i am new to this whole thing.
1.
Excessive db writer processes can be overhead due to each working set requires it's own db lru latches.
2.
Excessive db writer processes can slow down I/O due to they need to acquire CPU and then run. But one question here is does all db writer process simultinouses compete for cpu or it waits for one to complete and then go to other cpu. As, i can understand cpu uses serialize mechanism but lets say we have 12 dbwriter among one is writing using one cpu and other cpu is free. So, other process can move to that or db writer process is also serial ?
3.
Also, this can lead to wrong buffer waits situation as we can have free buffer in other sets and in one set it won't and process acquire that dbwriter so that it will post this wait event but actually we have other free buffers available. How to find this as how many buffers are available, dirty or in other state for each working set ?
4.

Get all values from request.getParameter
In ASP, I can do something like that...
For each item in Request.Form
Response.write "Name is:" & item & " value is:" & Request(item)
Next
How about in JSP? How do i get the names and values of the form using a loop?You can use request.getParameterNames() which will return an enumeration, then you can iterate through the enumeration and use request.getParameterValue(String paramName) method to get the values.

Error while assigning a character value to a numeric variable.
I fire a sql statement and check the number of rows returned by the sql.
I check this result with the application logs.
The application logs keeps the sqls fired by the application and the no of rows returned, in the example below the sql returned 8454 rows.
My script compares the two results.

How do I change the value assigned to resB into a numeric variable?

to this:
resB=`grep '3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD,' BCVP_Main_Loader.qvw.log | awk '{print $10}' | tr -d ,`
to drop the comma. Or you could do it in awk(1):
resB=`grep '3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD,' BCVP_Main_Loader.qvw.log | awk '{ gsub( /,/, "", $10 ); print $10}'`
Or you could to it all in awk(1):
resB=`awk '
/3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD/ {
gsub( /,/, "", $10 )
print $10
' BCVP_Main_Loader.qvw.log`
(This example was not tested, it's just for a model.)
Someone more of an SQL guru than I can probably tell you how to change your numeric locale to avoid presenting those commas in the first place and avoid the problem.

Issue in Creation of new Value Field in CO-PA
Hi,
I have a query in CO-PA Value Field Linking.
In my Development Client,
1. Created a New Value Field (No Transport Request Generated)
2. Linked to the above to new Conditon type created in SD. (Tranport request was generated) i.e. in Flow of Actual Values->Transfer of Billing Documents->Assign Value Fields
However then i try creating a new Value Field in my Production Client it throws a message 'You have no authorization to change Fields".
Is this an issue with authorization or i need to transport the Value field too from Development to Production client.
Please Advise.
Thanks in Advance,
SafiThanks Phaneendra for the response.
The creation of Value field did not create any tranportation request. Will this too be transported if i transport the Operating Concern.
Please Advise.
Thanks,

If you really, really want to use BETWEEN (which includes both end points), then you could do it with date arithmentic:

Unable to capture return values in web services api
At the time of login to web services if my server is down ,
it returns following error :
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(String.java:1438)
at java.lang.String.substring(String.java:1411)
I want to capture this error so that i can try another server to login. how do i capture this error
Another place where i want to capture the return Value is when i look for a report on the server
rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
"@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
oInfoObjects = rh.getInfoObjects();
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
Here if the report is not there on the server , it returns a null handler exception.
but if i try catching it by checking my responsehandler is null like rh == null it does not catch it.
Any help will be appreciated
thanks
Rakesh GuptaTed : i have two cases
1) server = server_st.nextToken();
providerURL = "http://"server"/dswsbobje/services";
sessConnURL = new URL(providerURL + "/session");
Connection boConnection = new Connection(sessConnURL);
Session boSession = new Session(boConnection);
EnterpriseCredential boEnterpriseCredential = new EnterpriseCredential();
boEnterpriseCredential.setLogin(userid);
boEnterpriseCredential.setPassword(pwd);
boEnterpriseCredential.setAuthType(auth);
SessionInfo boSI = boSession.login(boEnterpriseCredential);
I have got a list of servers running web servcies stored in my tokens. when i pass the first server name say " test:8080" and that server is down , i want to catch somewhere in the code above that it did not get the connection so that i can loop back and try with the second server say test1:8080
This is for failover purposes.
at present when i was trying to capture return value of boSI it breaks giving the error
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(String.java:1438)
at java.lang.String.substring(String.java:1411)
2nd case :
I am geeting reports from the server and scheduling them:
i run the following code which works fine if reports is there
rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
"@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
oInfoObjects = rh.getInfoObjects();
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
Here if the report is not there on the server then i should be able to catch from the response handle rh that it has got a null value.
but rh does not return a null value
the code ultimately throws a null handle at the following line
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
i am not able to catch the null value there also.
hope you got my issue.

Just when I thought I new how progressive and interlaced are working....
Hey everyone. I thought I new the difference between progressive and interlaced but I've still got a few questions. For the most part... i get it. Progressive is like 1 solid picture. Interlaced breaks up the picture into interlaced lines and 2 field
