Best practices for gathering statistics in 10g

I would like to get some opinions on what is considered best practice for gathering statistics in 10g. I know that 10g has auto statistics gathering, but that doesn't seem to be very effective as I see some table stats are way out of date.
I have recommended that we have at least a weekly job that generates stats for our schema using DBMS_STATS (DBMS_STATS.gather_schema_stats). Is this the right approach to generate object stats for a schema and keep it up to date? Are index stats included in that using CASCADE?
Is it also necessary to gather system stats? I welcome any thoughts anyone might have. Thanks.

Hi,
Is this the right approach to generate object stats for a schema and keep it up to date? The choices of executions plans made by the CBO are only as good as the statistics available to it. The old-fashioned analyze table and dbms_utility methods for generating CBO statistics are obsolete and somewhat dangerous to SQL performance. As we may know, the CBO uses object statistics to choose the best execution plan for all SQL statements.
I spoke with Andrew Holsworth of Oracle Corp SQL Tuning group, and he says that Oracle recommends taking a single, deep sample and keep it, only re-analyzing when there is a chance that would make a difference in execution plans (not the default 20% re-analyze threshold).
I have my detailed notes here:
http://www.dba-oracle.com/art_otn_cbo.htm
As to system stats, oh yes!
By measuring the relative costs of sequential vs. scattered I/O, the CBO can make better decisons. Here are the data items collected by dbms_stats.gather_system_stats:
No Workload (NW) stats:
CPUSPEEDNW - CPU speed
IOSEEKTIM - The I/O seek time in milliseconds
IOTFRSPEED - I/O transfer speed in milliseconds
I have my notes here:

Hope this helps. . . .

SQL 2008 R2 Best Practices for Updating Statistics for a 1.5 TB VLDB

We currently have a ~1.5 TB VLDB (SQL 2008 R2) that services both OLTP and DSS workloads pretty much on a 24x7x365 basis. For many years we have been updating statistics (full scan- 100% sample size) for this VLDB once a week on the weekend, which
is currently taking up to 30 hours to complete.
Somewhat recently we have been experiencing intermitent issues while statistics are being updated, which I doubt is just a coincidence. I'd like to understand exactly why the process of updating statistics can cause these issues (timeouts/errors). My theory
is that the optimizer is forced to choose an inferior execution plan while the needed statistics are in "limbo" (stuck between the "old" and the "new"), but that is again just a theory. I'm somewhat surprised that the "old" statistics couldn't continue to
get used while the new/current statistics are being generated (like the process for rebuilding indexes online), but I don't know all the facts behind this mechanism yet so that may not even apply here.
I understand that we have the option of reducing the sample percentage/size for updating statistics, which is currently set at 100% (full scan). Reducing the sample percentage/size for updating statistics will reduce the total processing time, but
it's also my understanding that doing so will leave the optimizer with less than optimal statistics for choosing the best execution plans. This seems to be a classic case of not being able to have one’s cake and eat it too.
So in a nutshell I'm looking to fully understand why the process of updating statistics can cause access issues and I'm also looking for best practices in general for updating statistics of such a VLDB. Thanks in advance.

I'm with you. Yikes is exactly right with regard to suspending all index optimizations for so long. I'll probably start a separate forum thread about that in the near future, but for now lets stick to the best practices for updating statistics.
I'm a little disappointed that multiple people haven't already chimed in about this and offered up some viable solutions. Like I said previously, I can't be the first person in need of such a thing. This database has 552 tables with a whole lot more statistics
objects than that associated with those tables. The metadata has to be there for determining which statistics objects can go (not utilized much if at all so delete them- also produce an actual script to delete the useless ones identified) and what
the proper sample percentage/size should be for updating the remaining, utilized statistics (again, also produce a script that can be used for executing the appropriate update statistics commands for each table based on cardinality).
The above solution would be much more ideal IMO than just issuing a single update statistics command that samples the same percentage/size for every table (e.g. 10%). That's what we're doing today at 100% (full scan).
Come on SQL Server Community. Show me some love :)

Best Practices for deployment of Oracle 10g database.

Hello ,
Is anyone aware of a whitepaper/ document that talks about best pratices in deploying a database on Oracle 10g and configuration of the database to utilize all the features available in 10g ( eg. ADDM , reports setup etc )
Thanking you in Advance.
Cheers..rCube

Appreciate the input Jaffer. Thanks.
However I was referring to a Best Practices whitepaper like the one existing for Data Guard & MAA available at the follwogng url : - http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm
Is there something available along the same lines ?

Best Practice for installing/managing 9i/10g RAC

Looking for this notes/articles...

There is one best practice document available from Oracle RACSIG site and "Oracle Real Applicaiton Cluster Administration and Deployment Guide" available on OTN is also good source of informaiton about 10g RAC.
Oracle has made sincere efforts in 10g documentations expecially in server technology.
Thanks & Regards

Best Practice for Resolving OAS 10g R3 Classloading Issues

What's the best practices for eliminating classloading issues for shared libraries that are loaded by default (apache.commons.logging, oracle.toplink, etc) in OAS 10g R3?
So far it looks like my options are to exclude the conflicting JARs in my deployed applications or manually remove the entries from the application.xml and system-application.xml files in the OC4J instance config directory.
I know that I can override the shared libraries loaded from the system-application.xml by using the <web-app-class-loader search-local-classes-first="true"/> element in my orion-web.xml but is that the best practice? Also note that this solution does not override the apache.commons.logging shared library loaded from the container's application.xml.
So what is the best practice?

Best practice for PK and indexes?

Dear All,
What is the best practice for making Primary Key and indexes? Should we keep them in the same tablespace as table or should we create a seperate tableapce for all indexes and Primary Key? Please note I am talking about a table that has 21milion rows at the moment and increasing 10k to 20k rows daily. This table is also heavily involved in daily reports and causing slow performance. Currently the complete table with all associated objects such as indexes and PK is stored in one seperate tablespace. If my way is right then please advise me how can I improve the performance of retrival or DML operation on this table?
Thanks in advance..
Zia Shareef

Well, thanks for valueable advices... I am using Oracle 8i and let me tell you exact problem...
My billing database has two major tables having almost 21 millions rows each... one has collection data and other one for invoices... many reports are showing the data with the joining of Customer + Collection + Invoices tables.
There are 5 common fields in between invoices(reading) and collection tables
YEAR, MONTH, AREA_CODE, CONS_CODE, BILL_TYPE(adtl)
My one of batch process has following update and it is VERY VERY SLOW:
UPDATE reading r
SET bamount (SELECT sum(camount)
FROM collection cl
WHERE r.ryear = cl.byear
AND r.rmonth = cl.bmonth
AND r.area_code = cl.area_code
AND r.cons_code = cl.cons_code
AND r.adtl = cl.adtl)
WHERE area_code = 1
tentatively area_code(1) is having 20,000 consumers
each consuemr may have 72 invoices and against these invoices it may have 200 rows in collection tables (system have provision to record partial payment against one invoice)
NOTE: Please note presently my process is based on cursors so the above query runs for one consumer at one time but just for giving an idea I have made it for whole area.
Mr. Yingkuan, can you please tell me how can I check that the table' statistics is not current and how can I make it current. Is it really effect performance?

Best practice for use of spatial operators

Hi All,
I'm trying to build a .NET toolkit to interact with Oracles spatial operators. The most common use of this toolkit will be to find results which are within a given geometry - for example select parish boundaries within a county.
Our boundary data is high detail, commonly containing upwards of 50'000 vertices for a county sized polygon.
I've currently been experimenting with queries such as:
select
from
uk_ward a,
uk_county b
where
UPPER(b.name) = 'DORSET COUNTY' and
sdo_relate(a.geoloc, b.geoloc, 'mask=coveredby+inside') = 'TRUE';
However the speed is unacceptable, especially as most of the implementations of the toolkit will be web based. The query above takes around a minute to return.
Any comments or thoughts on the best practice for use of Oracle spatial in this way will be warmly welcomed. I'm looking for a solution which is as quick and efficient as possible.

Thanks again for the reply... the query currently takes just under 90 seconds to return. Here are the results from the execution plan ran in sql*:

All i want to do with this is generate results which fall in a particular geometry. Most of my testing has been successful i just seem to run into issues when querying against a county sized polygon - i guess due to the amount of vertices.
Also looking through the forums now for tuning topics...

Best Practice for module components based on API's

Hi all,
is there a white paper/other documents which outline best
practice for using table/module component api's and best
approaches to get around restrictions?
I would also appreciate war stories about using this method of
Forms development bearing in mind i would be using this as the
foundation of a web deployed based application (intranet first -
ultimately internet).
Thanks

You cannot add agents to skills dynamically; however, you can queue the caller into more than one CSQ based on statistics. You would use the Get Reporting Statistics and an If step within the Queued branch of your first Select Resource step. If the condition is met (e.g. Contacts Waiting >= 10) then exectue a second Select Resource step within the queued branch of the first. The contact would then be waiting in both CSQs waiting for an agent.

Best practice for ASA Active/Standby failover

Hi,
I have configured a pair of Cisco ASA in Active/ Standby mode (see attached). What can be done to allow traffic to go from R1 to R2 via ASA2 when ASA1 inside or outside interface is down?
Currently this happens only when ASA1 is down (shutdown). Is there any recommended best practice for such network redundancy? Thanks in advanced!

Best Practices for NCS/PI Server and Application Monitoring question

Hello,
I am deploying a virtual instance of Cisco Prime Infrastructure 1.2 (1.2.1.012) on an ESX infrastructure. This is being deployed in an enterprise enviroment. I have questions around the best practices for moniotring this appliance. I am looking to monitor application failures (services down, db issues) and "hardware" (I understand this is a virtual machine, but statistics on the filesystem and CPU/Memory is good).
Firstly, I have enabled via the CLI the snmp-server and set the SNMP trap host destination. I have created a notification receiver for the SNMP traps inside the NCS GUI and enabled the "System" type alarm. This type includes alarms like NCS_DOWN and PI database is down. I am trying to understand what the difference between enabling SNMP-SERVER HOST via the CLI and setting the Notification destination inthe GUI is? Also how can I generate a NCS_DOWN alarm in my lab. Doing NCS stop does not generate any alarms. I have not been able to find much information on how to generate this as a test.
Secondly, how and which processes should I be monitoring from the Management Station? I cannot easily identify the main NCS procsses from the output of ps -ef when logged in the shell as root.
Thanks guys!

1.) What is the cost of having the scope in a <jsp:useBean> tag set to 'session'? I am aware that there are a list of scopes like page, application, etc. and that if i use 'session' my variable will live for as long as that session is alive. (did i get this right?). You should rather look to the functional requirements instead of costs. If the bean need to be session scoped (e.g. maintain the logged in user), then do it so. If it just need to be request scoped (e.g. single page form data), then keep it request scoped.
2.)If the JSP Page where i use that <useBean> is to be accessed hundred of times a day, will it compensate my server resources? Right now i am using the Sun Glassfish Server.It will certainly eat resources. Just supply enough CPU speed and memory to a server. You cannot expect that a webserver running at a Pentium 500MHz with 256MB of memory can flawlessly serve 100 simultaneous users at the same second. But you may expect that it can serve 100 users per 24 hour.
3.) Can you suggest best practice in memory management given the architecture i described above?Just write code so that it doesn't unnecessarily eat memory. Only allocate memory if your application need to do so. You should rather let the hardware depend on the application requirements, not to let the application depend on the hardware specs.
4.)Also, I have implemented connection pooling in my architecture, but my application is to be used by thousands of clients everyday.. Can the Sun Glassfish Server take care of that or will I have to purchase a powerful sever?Glassfish is just an application server software, it is not server hardware. Your concerns are rather hardware related.

Where to find best practices for tuning data warehouse ETL queries?

Hi Everybody,
Where can I find some good educational material on tuning ETL procedures for a data warehouse environment? Everything I've found on the web regarding query tuning seems to be geared only toward OLTP systems. (For example, most of our ETL
queries don't use a WHERE statement, so the vast majority of searches are table scans and index scans, whereas most index tuning sites are striving for index seeks.)
I have read Microsoft's "Best Practices for Data Warehousing with SQL Server 2008R2," but I was only able to glean a few helpful hints that don't also apply to OLTP systems:
often better to recompile stored procedure query plans in order to eliminate variances introduced by parameter sniffing (i.e., better to use the right plan than to save a few seconds and use a cached plan SOMETIMES);
partition tables that are larger than 50 GB;
use minimal logging to load data precisely where you want it as fast as possible;
often better to disable non-clustered indexes before inserting a large number of rows and then rebuild them immdiately afterward (sometimes even for clustered indexes, but test first);
rebuild statistics after every load of a table.
But I still feel like I'm missing some very crucial concepts for performant ETL development.
BTW, our office uses SSIS, but only as a glorified stored procedure execution manager, so I'm not looking for SSIS ETL best practices. Except for a few packages that pull from source systems, the majority of our SSIS packages consist of numerous "Execute
SQL" tasks.
Thanks, and any best practices you could include here would be greatly appreciated.

Best Practices for BI, ADF and Oracle Forms installations on Weblogic

Hi, I'm researching options on upgrading to Oracle 11g Middleware. My company currently has Oracle Forms 10g running on Oracle Application Server.
We are interested in using Oracle Forms 11g, ADF and Jdeveloper, and Business Intelligence with Oracle's Weblogic 10.3.5.
Is there any whitepapers or documentation on best practices for installing alll of these components together?
For instance, can ADF ( with JSF 2.x ) be installed in the same domain as Oracle Forms 11g but use different managed servers?
Will Business Intelligence need to be in a seperate Oracle Home with it's own weblogic installation? I spend a lot of time trying to get the JSF upgraded to 2.x in the Business Intelligence installation and could not get it to work.
I know it's a pretty broad question but thank you for any direction on this.

Thanx for the reply! I read through the documents and they are very good at explaining how to install the different components individually. I still can't find much on installing them together. I hope it's not just going to be a trial and error thing.
So far I've installed done the following successfully:
Installed 10.3.5 weblogic
Forms and Reports 11g on top of 10.3.5
I've created an additional managed server for our ADF applications.
My next step is upgrading the JSF to 2.x. I would have to stage patches 12917525 and 12979653. I'm afraid it will break the forms and reports though. Any ideas?

What are the best practices for the RCU's schemas

Hi,
I was wondering if there is some best practices about the RCU's schemas created with BIEE.
I already have discoverer (and application server), so I have a metadata repository for the Application Server. I will upgrade Discoverer 10g to 11, so I will create new schema with RCU in my metada repository (MR) of the Application Server. I'm wondering if I can put the BIEE's RCU schemas in the same database.
Basically,
1. is there a standard for the PREFIX ?
2. If I have multiple components of Fusion in the same Database, I will have multiples PREFIX_MDS schema ? Can they have the same PREFIX ? Or They all need to have a different prefix ?
For exemple: DISCO_MDS and BIEE_MDS or I can have DEV_MDS and this schema is valid for both Discoverer and BIEE.
Thank you !

the DBA Team to connect and work with the ORACLE user.
What are the Best Practice for souch case ?
Thanks

To install databases you don't need acces to Oracle.
Also installing 'few databases every month' is fundamentally wrong as your server will run out of resources, and Oracle can host multiple schemas in one database.
"One reason for example is that we have many shell scripts that user ORACLE is the owner of them and only user ORACLE have a privilege to execute them."
Database control in 10g and higher makes 'scripts' obsolete. Also as long as you don't provide w access to the dba group there is nothing wrong in providing x access.
You now have a hybrid situation: they are allowed interactively to screw 'your' databases, yet they aren't allowed to run 'your' script.
Your security 'model' is in urgent need of revision!

Best practices for setting up users on a small office network?

Hello,
I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
Thank you,

Hi,
