Best practice for statistic collection in 10gR2

Hello,
In Oracle 9i, I had to run every day scripts to calculate statistics.
But in Oracle 10gR2, the collection of statistics has become automatic...I would like some feebback from your experience:
1/ Does it work well?
2/ Do I still need to run my own scripts to calculate statistics as in 9i?
3/ What are the options or parameter to activate to get the best result in 10gR2
4/ Please, give me the best practice to implement the automatic statistic collection in 10gR2
Thanks for your help

Some more question on this topic :
a/ what happens when a empty table is loaded suddenly and there is a query on that...is the statistic calculated at once?no, it would be normal to run dbms_stats manually as part of significant loads
b/ is there any timing for Oracle to launch the statistic collection? the default schedule for maintenance jobs including stats is 10pm - (IIRC) 8am every night and all weekend i.e weeknights and weekends.
c/ is it possible to launch statistic collection only the night when the load is low?see above.

Best practices for pass collections and to navigate between 2 view endlessl

Hello, I have a doubt about efficiency and optimization of memory in this case. I have a managedBean for to show a activities´s list, then I can select one activity and the application redirects another view. This view is controlled for another managedBean for to show the specificied activity.
My idea is pass the collection and the id of specificied activity to he second managedBean, and since second managedBean pass the collection to the first managedBean.
I had thought pass properties by request and retrieve in the second bean, but I am not sure wich scope to usea in both bean. Because, the first bean pass collection to the first again.
I also thought to use SessionScope in both bean, but I doubt about efficiency of memory in this case.
How to pass parameters is not yet defined:
-Using h:link and attributes
- Using setPropertyactionListener between both bean
-Others who do not know
First managedBean (show list)
@ManagedBean(name="actividades")
@ViewScoped I'm not sure which scope to use

What are best practice for packaging and deploying j2EE apps to iAS?

We've been running a set of J2EE applications on a pair of iAS SP1b for about a year and it has been quite stable.
Recently however we have had a number of LDAP issues, particularly when registering and unregistering applications (registering ear files sometimes fails 1st time but may work 2nd time). Also We've noticed very occasionally that old versions of classes sometimes find their way onto our machines.
What is considered to be best practice in terms of packaging and deployment, specifically:
1) Packaging - using the deployTool that comes with iAS6 SP1b to package is a big manual task, especially when you have 200+ jsp files. Are people out there using this or are they scripting it with a build tool such as Ant?
2) Deploying an existing application to multiple iAS's. Are you guys unregistering old application then reregistering new application? Are you shutting down iAS whilst doing the deployment?
3) Deploying ear files can take 5 to 10 mins, is this normal?
4) In a clustered scenario where HTTPSession is shared what are the consequences of doing deployments to data stored in session?
thanks in asvance for your replies

You may want to consider upgrading your application server environment to a newer service pack. There are numerous enhancements involving the deployment tool and run time layout of your application that make clear where you're application is loading its files from.
If you've at a long running application server environment, with lots of deployments under your belt, you might start to notice slow downs in deployment and kjs start time. Generally this is due to garbage collecting in your iAS registry.
You can do several things to resolve this. The most complete solution is to reinstall the application server. This will guarantee a clean ldap registry. Of course you've got to restablish your configurations and redeploy your applications. When done, backup your application server install space with the application server and directory server off. You can use this backup to return to a known configuation at some future time.
For the second method: <B>BE CAREFUL - BACKUP FIRST</B>
There is a more exhaustive solution that involves examining your deployed components to determine the active GUIDS. You then search the NameTrans section of the registry searching for Applogic Servlet *, and Bean * entries that represent your previously deployed components but are represented in the set of deployed GUIDs. Record these older GUIDs, remove them from ClassImp and ClassDef. Finally remove the older entries from NameTrans.
Best practices for deployment depend on your particular environmental needs. Many people utilize ANT as a build tool. In later versions of the application server, complete ANT scripts are included that address compiling, assembly and deployment. Ant 1.4 includes iAS specific targets and general J2EE targets. There are iAS specific targets that can be utilized with the 1.3 version. Specialized build targets are not required however to deploy to iAS.
Newer versions of the deployment tool allow you to specify that JSPs are not to be registered automatically. This can be significant if deployment times lag. Registered JSP's however benefit more fully from the services that iAS offers.
2) In general it is better to undeploy then redeploy. However, if you know that you're not changing GUIDs, recreating an existing application with new GUIDs, or removing registered components, you may avoid the undeploy phase.
If you shut down the KJS processes during deployment you can eliminate some addition workload on the LDAP server which really gets pounded during deployment. This is because the KJS processes detect changes and do registry loads to repopulate their caches. This can happen many times during a deployment and does not provide any benefit.
3) Deploying can be a lengthy process. There have been improvements in that performance from service pack to service pack but unfortunately you wont see dramatic drops in deployment times.
One thing you can do to reduce deployment times is to understand the type of deployment. If you have not manipulated your deployment descriptors in any way, then there is no need to deploy. Simply drop your newer bits in to the run time space of the application server. In later service packs this means exploding the package (ear,war, or jar) in to the appropriate subdirectory of the APPS directory.
4) If you've changed the classes of objects that have been placed in HTTPSession, you may find that you can no longer utilize those objects. For that reason, it is suggested that objects placed in session be kept as simple as possible in order to minimize this effect. In general however, is not a good idea to change a web application during the life span of a session.

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 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:
http://www.dba-oracle.com/t_dbms_stats_gather_system_stats.htm
Hope this helps. . . .

Best practice for dealing with Recordsets

Hi all,
I'm wondering what is best practice for dealing with data retrieved via JDBC as Recordsets without involving third part products such as Hibernate etc. I've been told to NOT use RecordSets throughout in my applications since they are taking up resources and are expensive. I'm wondering which collection type is best to convert RecordSets into. The apps I'm building are webbased using JSPs as presentation layer, beans and servlets.
Many thanks
Erik

There is no requirement that DAO's have a direct mapping to Database Tables. One of the advantages of the DAO pattern is that the business layer isn't directly aware of the persistence layer. If the joined data is used in the business code as if it were an unnormalized table, then you might want to provide a DAO for the joined data. If the joined data provides a subsiduray object within some particular object, you might add the access method to the DAO for the outer object.
eg:
In a user permissioning system where:
1 user has many userRoles
1 role has many userRoles
1 role has many rolePermissions
1 permission has many rolePermissions
ie. there is a many to many relationship between users and roles, and between roles and permissions.
The administrator needs to be able to add and delete permissions for roles and roles for users, so the crud for the rolePermissions table is probably most useful in the RoleDAO, and the crud for the userRoles table in the UserDAO. DOA's also can call each other.
During operation the system needs to be able to get all permissions for a user at login, so the UserDAO should provide a readPermissions method that does a rather complex join across the user, userRole, rolePermission and permission tables..
Note that f the system I just described were done with LDAP, a Hierarchical database or an Object database, the userRoles and rolePermissions tables wouldn't even exist, these are RDBMS artifacts since relational databases don't understand many to many relationships. This is good reason to avoid providing DAO's that give access to those tables.

Best Practice for Retiring Superseded or Expired Updates

If you want to clear out superseded or expired updates, do you delete them from your update package, the deployment package, or both? Or is there another best practice for this?
Thanks,
Bryan

Hi Torsten, im reading this article because im actualy planing to solve some kind of the the same problem.
I create Software Update Groups with monthly patches, and then i will deploy this to certain Client Collections.
If there becomes a single Patch, the Status, "expired", out of the Software Update Group, what would be the effect for the whole Software Update Group wich still have an active deployment?
Thanks for your sugestion.

What are the best practice for CQ5.5 configuration?

Hello,
What are the best practice for CQ5.5 configuration which handle for High availability.
Last time I had a issues on server when I was uploaded 2 GB of DAM and then after that the server is not able to start and always getting error regarding Tar Persistance.
So kindly request you to please let me know what are the best apache felix configuration.
Thanks in advance...
Regards,
Satish

Hi,
A DAM upload, regardless of the size of the assets, never should result in TarPM problems, unless you run into an OOM, which left the repository in an unclean state. So if you regularly do DAM uploads of that size, you should check the Garbage Collection logs and probably adjust the heapsize if necessary. You might want to limit the number of concurrent running workflows to keep the memory consumption a bit lower.
To your question: HA in a traditional sense you cannot achieve with a single box, even with optimized settings. In an author usecase you would need clustering.

Best Practices for FSCM Multiple systems scenario

Hi guys,
We have a scenario to implement FSCM credit, collections and dispute management solution for our landscape comprising the following:
a 4.6c system
a 4.7 system
an ECC 5 system
2 ECC6 systems
I have documented my design, but would like to double check and rob minds with colleagues regarding the following areas/questions.
Business partner replication and synchronization: what is the best practice for the initial replication of customers in each of the different systems to business partners in the FSCM system? (a) for the initial creation, and (b) for on-going synchronization of new customers and changes to existing customers?
Credit Management: what is the best practice for update of exposures from SD and FI-AR from each of the different systems? Should this be real-time for each transaction from SD and AR (synchronous) or periodic, say once a day? (assuming we can control this in the BADI)
Is there any particular point to note in dispute management?
Any other general note regarding this scenario?
Thanks in advance. Comments appreciated.

Hi,
I guess when you've the informations that the SAP can read and take some action, has to be asynchronous (from non-SAP to FSCM);
But when the credit analysis is done by non-SAP and like an 'Experian', SAP send the informations with invoices paid and not paid and this non-SAP group give a rate for this customer. All banks and big companies in the world does the same. And for this, you've the synchronous interface. This interface will updated the FSCM-CR (Credit), blocking or not the vendor, decreasing or increasing them limit amount to buy.
So, for these 1.000 sales orders, you'll have to think with PI in how to create an interface for this volume? What parameters SAP does has to check? There's an time interval to receive and send back? Will be a synchronous or asynchronous?
Contact your PI to help think in this information exchange.
Am I clear in your question?

What are the Best Practices for Optimizing Images in InDesign Files

Is there a best practice for using images InDesign to optimize the document before converting to a PDF? Specifically, what I'm asking is, will the PDF file compress better if the images are cropped prior to placing them in Indesign? I'd like to know the answer for both creating PDF files for printing using images that are 300dpi and for creating PDF files for online delivery using images that are 72dpi. I have an employee that insists images need to be cropped to actual dimensions before placing in the InDesign document. I've never done it that way and believe that her recommended process is way too time consuming and leaves you with no leeway to tweak your page design since the images are tightly cropped.

As for absolute cropping, I agree with your stance. Until the layout is fixed, preserving your ability to easily manipulate photo size and positioning is key.
Some clever image management methods have been described in the discussion forums, and one that appealed most to me was the use of duplicate linked image folders. Having a high-res (CMYK) folder and a low-res (RGB) folder to switch between for different output enables you to use both to your advantage. Use the low-res images for layout, for internal proofing, and for EPUB/online PDF/HTML output. Then it's simply a quick switch to the high-res image folder for print purposes. You can easily prepare the alternate collection of images with a Photoshop batch convert script or with the Photoshop Image Processor. Save your presets!

Best Practices for Data Access

Good morning!
I was wondering if someone might give me some advice on some best practices for retrieving data from a SQL server in the cloud via a desktop application?
I'm curious if I embed into my desktop application the server address (IP, or Domain or whatever) and allow the users to provide their own usernames and passwords when using the application, if there was anything "wrong" with that? Where-in my
application collects the username and password from the user, connects to a server with that username and password, retrieves the data and uses it in-app.
I'm petrified of security issues and I would hate to start using a SQL database with this setup only to find out that anyone could download x, y or z and connect to the database and see everything.
Assuming I secure all of the users with limited permissions, is there anything wrong with exposing a SQL server to the web for my application to use? If so, what and what would be a reasonable alternative?
I really appreciate any help and feedback!

There are two options, none of them very palatable:
1) One is to create a domain, and add the VM and your local box to it.
2) Stick to a workgroup, but have the same user name and password on both machines.
In practice, a better option is to create an SQL login that is member of sysadmin - or who have rights to impersonate an account that is member of sysadmin. And for that matter, you could use the built-in sa account - but you rename it to something else.
The other day I was looking at the error log from a server that apparently had been exposed on the net. The log was full with failed login attempts for sa, with occasional attempts for names like usera and so on. The server is in Sweden - the IP address
for the login attempts were in China.
Just so know what you can expect.

Is there a list of best practices for Azure Cloud Services?

Hi all;
I was talking with a Sql Server expert today and learned that Azure Sql Server can take up to a minute to respond to a query that normally takes a fraction of a second. This is one of those things where it's really valuable to learn it when architecting as
opposed to when we go live.
Cloud Services are not Sql Server (obviously) but that led to the question - Is there a list of best practices for Azure Cloud Services? If so, what are they?
We will be placing the cloud services in multiple datacenters and using traffic manager to point people to the right one. The cloud service will set between an IMAP client & server, pretending to be the mail client to the server, and the server to the client.
Mostly it will pass all requests & responses across from one to the other.

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,
Thanks for your posting.
When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

Best-practice for Catalog Views ? :|

Hello community,
A best practice question:
The situtation: I have several product categories (110), several items in those categories (4000) and 300 end-users. I would like to know which is the best practice for segment the catalog. I mean, some users should only see categories 10,20 & 30. Other users only category 80, etc. The problem is how can I implement this ?
My first idea is:
1. Create 110 Procurement Catalogs (1 for every prod.category). Each catalog should contain only its product category.
2. Assign in my Org Model, in a user-level all the "catalogs" that the user should access.
Do you have any idea in order to improve this ?
Saludos desde Mexico,
Diego

Hi,
Your way of doing will work, but you'll get maintenance issues (to many catalogs, and catalog link to maintain for each user).
The other way is to built your views in CCM, and assign these views to the users, either on the roles (PFCG) or on the user (SU01). The problem is that with CCM 1.0 this is limitated, cause you'll have to assign one by one the items to each view (no dynamic or mass processes), it has been enhanced in CCM 2.0.
My advice:
-Challenge your customer about views, and try to limit the number of views, with for example strategic and non strategic
-With CCM 1.0 stick to the procurement catalogs, or implement BADIs to assign items to the views (I experienced it, it works, but is quite difficult), but with a limitated number of views
Good luck.

Best Practice for Securing Web Services in the BPEL Workflow

What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
They are all deployed on the same oracle application server.
Defining agent for each?
Gateway for all?
BPEL security extension?
The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
Regards
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.
Thanks
