A question on different options for data archival and compression

Hi Experts,
I have production database of about 5 terabyte size in production and about 50 GB in development/QA. I am on Oracle 11.2.0.3 on Linux. We have RMAN backups configured. I have a question about data archival stretegy. To keep the OLTP database size optimum, what options can be suggested for data archival?
1) Should each table have a archival stretegy?
2) What is the best way to archive data - should it be sent to a seperate archival database?
In our environment, only for about 15 tables we have the archival stretegy defined. For these tables, we copy their data every night to a seperate schema meant to store this archived data and then transfer it eventualy to a diffent archival database. For all other tables, there is no data archival stretegy.
What are the different options and best practices about it that can be reviewed to put a practical data archival strategy in place? I will be most thankful for your inputs.
Also what are the different data compression stregegies? For example we have about 25 tables that are read-only. Should they be compressed using the default oracle 9i basic compression? (alter table compress).
Thanks,
OrauserN

You are using 11g and you can compress read only as well as read-write tables in 11g. Both read only and read write tables are the candidate for compression always. This will save space and could increase the performance but always test it before. This was not an option in 10g. Read the following docs.

Remove option for Data Tracking and Drill Mode

Hi all
We have integrated a bunch of Webi reports into the SAP Portal. My question is now how to remove the options about Data Tracking and Drill Mode in the top right hand corner? I guess it is some special right we need to deny in the Access Level, we have defined. But if I deny data tracking and drilling in the Web Intelligence section of the Access Level, it has no effect.
Please assist.
Best regards,
Martin Søgaard

I, too, am perplexed by this change. Then again, I've been perplexed by most of the changes Apple has made to products/os in the last few years. I'm thinking that I may not only change browsers, but hardware/software also. It's issues like this that make me wonder if anyone on the Apple design team actually uses any of their products, or maybe they think we are all just too ignorant to be able to use a computer.
Making things simple to use shouldn't equate to removing advanced functionality, but it seems that's what Apple believes it to be.
Really disgusted now.
Thanks Apple.

Hard drive failure - options for data recovery and AppleCare coverage

I have been handed a relative's 12 month old MacBook Pro with a factory-installed 500GB hard drive which appears to have failed. When attempting to boot the MacBook I am met with the classic clicking and grating noise which I know is a tell-tale sign of hard drive failure. The drive will not boot and I am shown the question mark folder icon, indicating that the operating system cannot be found. Have booted into internet recovery mode, Disk Utility appears to have found no sign of the hard drive's existence and shows none of its partitions. I have attempted putting the MacBook into FW target-mode and mounting the disk from another laptop, but to no avail; while it will go into target mode the drive simply isn't visible. The SATA connection to the drive is definitely OK - I have tested with another 2.5 inch hard drive which showed up fine in Disk Utility and was bootable. Have run Apple Hardware Test/Diagnostics but this returned no errors. It seems like a pretty clear cut case of drive failure.
I put this all to the relative whose laptop this is and asked them whether the MacBook had been dropped recently, explaining to them that this is one of the likeliest causes for such sudden failure. Sheepishly they admitted that they had indeed dropped it, although not from too great a distance and onto a carpeted floor. Apparently in the days immediately after the shock the hard drive continued to boot but the system was very slow and beset by spinning beech ball hangups. It is only in the last few days that the hard drive has become completely unbootable, and seemingly unreachable.
I have two questions that I would be grateful for some help with.
Firstly, is there any possibility of recovering data from this drive without going to a data recovery specialist? The user did have backups of most important data, but some recently imported photos were not backed up. Is it any use me trying any third-party data recovery software utilities, bearing in mind that I can't even mount the drive in target mode?
Second, the MacBook is still covered by the extended AppleCare warranty for the next two years. Is it worth my relative's while making a Genius Bar appointment to see whether Apple would replace this drive for free, given that the damage was most likely user-inflicted? Is there any chance that this sudden failure could be unrelated to the drop the MacBook suffered the other day - perhaps just a result of the 'normal' failure rate? I am more than happy to exchange the drive for a new one myself and my relative is happy to pay for the new part (I was amazed at how cheap hard drives are now), but would we be better off trying an Apple Store? My prediction would be that while we might get lucky and have an obliging genius who agrees to swap the drive without asking too many questions, we could also have one who concludes the damage is not covered by the warranty and insists on charging for the new hard drive (at a mark-up I assume) and labour.
Any thoughts about these two issues or the hard drive failure more generally are very welcome. Thanks.

1, Data recovery software is your only alternative if there is no backup. It may or may not be able to revoker anything from that hard drive. If it does then the only other choice is to go to a data recovery service. If have to go that route expect to pay for it, like $$$$.
2, Yes. They will at least tell him what the problem is and the cost if any to fix. There is a good chance they will fix it for nothing and only charge for data recovery if they can do it.

Data archival and purging for OLTP database

Hi All,
Need your suggestion regarding data archival and purging solution for OLTP db.
currently, we are planning to generate flat files from table..before purging the inactive data and move them to tapes/disks for archiving then purge the data from system. we have many retention requirements and conditions before archival of data. so partition alone is not sufficient.
Is there any better approach for archival and purging other than this flat file approach..
thank you.

vara

Hi
Archive Selection
Use
For some archiving actions it is necessary to select individual archive files or whole archive sessions and make them available for the relevant action. You do this in the Archive Selection screen, which is accessible from the initial screen of the relevant action.
Archive selection is relevant for the following actions:
Delete
Read
Build index
Reload
Postprocessing
Prerequisites
Depending on the action, there are four different criteria for whether archiving sessions and archive files are displayed in the archive selection:
Criterion 1
Archive file status
Action
Criterion
Delete
Archive file status
Archived or
Stored (if sequence "Store before deletion" has been selected in Customizing)
Read
Archive file status Archived
or
Deleted
or
Saved
Build index
Archive file has the status Deleted and the file is in the file system
Reload
Archive file is in file system and the session has the corresponding status (see criterion 5)
Postprocessing
All archive files have status Deleted
Criterion 2
The archive file must contain at least one data object. If you have performed an archiving session and maintained the variants so that no data objects were archived, the archive file is automatically deleted and no longer offered for selection.
Criterion 3
If a file is not accessible in the file system, the file is not offered for selection. A file is only offered for read if all the files in a session are accessible.
While checking the accessibility of a file, the system performs a read access for each file. This check process can take a long time if there are a lot of files. To optimize this process the access check can be de-/activated according to archive files in file system and archive files in an optical archive in archiving object-specific Customizing.
Criterion 4
For client-dependent archiving objects only the sessions for the current client are offered.
Criterion 5
An archiving session can only be reloaded if it has the status Complete or Archiving session is reloaded.
Features
In the Archive Selection screen, which you can access by choosing Archive Selection from the initial screen of the archiving action, you can either select complete archive sessions or individual archive files.

Hi Ravi,
Use the Component WDR_SELECT_OPTIONS to include select options in Web Dynpro ABAP. Follow these steps:
1. In your Component , "Used Componet" tab add Component WDR_SELECT_OPTIONS . Component Use can be any name that you want to give, eg SELECT_OPTIONS
2. Go to the View where you want to include the Date Select Options. I am assuming that you already have an Attribute of Type DATS in your context.
3. View: Properties Tab:Create Controller Usage and select
SELECT_OPTIONS     WDR_SELECT_OPTIONS
SELECT_OPTIONS     WDR_SELECT_OPTIONS     INTERFACECONTROLLER

What are the different options for implementing web security?

Hi,
Right now I am working on an internet website. We are using JSP for presentation and running Weblogic Application Server. I want to know different options for implementing website security. One of the options that I am aware of is to use LDAP. But we donot want to go and buy a LDAP Directory Server now. So I would really appreciate if somebody could let me know my choices here.
Thanks in advance.

Hi,
If you are working on a Windows 2000 platform, the most obvious choice would be Active Directory Server as this is shipped free with Server 2000. It is LDAP compliant, although does have a few differences that set it apart from the other X500 standard based solutions which I will mention in a moment. Details on these differences can be found at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnactdir/html/msdn_activedirvsnds.asp
Other options are openldap, an open source implementation of an ldap server or iPlanet's Directory Server. If you are initially doing an evaluation, a trial version is available of the iPlanet software and can be downloaded from their site. I found this particularly easy to get to grips with and their is excellent documentation available. There is also an offering from Novell, but I have no experience of this.
Hope this helps.

Drop Down List in a table - different options for each row

How can i have a drop down list in a table with different options for each row?
My requirement is this.. I want to display, say employee dtails in a table, and one column is employee hobbies, whcih can have multiple values and each employee may have a different list of hobbies. So how can we populate the drop down for each row, with different options?

Hey. Uh, this probably isn't the answer you were looking for, but it sounds like you've got a problem with your database design there. Generally speaking, your tables shouldn't have multi-valued fields, in the relational model anyway (sql). Instead, you should look at adding a separate table like EMPLOYEE_HOBBIES. Then you have a foreign key using the employees primary key as the foreign key in the employee_hobbies table, see what I mean? I might have misunderstood your explanation though, I'm not sure.
Alternatively, you could just have hobbies as a big freeform varchar field, and don't bother to make people separate their hobbies into different fields (you'd have to abandon the drop-down listbox idea in this case). If there's no really important reason to make the distinction, then it's probably easier just to not do it.

Select option for date

i want give default values in select option for date (for a period)
I used
SELECT-OPTIONS y_s_mnth FOR y_v_dt_month default first to last OPTION BT.
first and last are dates.
I am getting error dialog box....specify ranges...
Please give sample code..

Hi Suhas,
I hope this code will help you. Reward me if it is helpful.
select-options : y_s_mnth FOR sy-datum.
initialization.
y_s_mnth-sign   = 'I'.
y_s_mnth-option = 'BT'.
y_s_mnth-low    = sy-datum - 30.    "first_day
y_s_mnth-high   = sy-datum.         "last_day
append y_s_mnth.
clear y_s_mnth.

Best Practise for Data Archiving

Hi All,
I have query in SAP that when business will do the data archving in their R3 systems.
On which basis they will do data archiving?
Is there any minimum period that data need's to be archived?
before doing the data archiving what they will do ?
Regards
Srini

Hi Srini,
1. SAP suggestes to implement data archiving strategy as early as possible to manage database growth .
However pople think of archiving when they realise the problems like large data volumes,slow system resonse time,performance issues etc...
2. There is a proper way to implement Data Archiving . Database has to be anaylzed first for getting the top DB tables and Archiving objects.
3. Based on the DB analysis ,Data archiving plan has to be implenemted according to data management guide.
4. There is a minimum period known as residence time has to be completed before any data to be archived. Once the document is business completed and serverd its minimum required period in the Database ,it can be archived.
5, Before going for data archiving there are many steps to be followed like analysis,configuration etc that you can see in details at the link below :

JDBC Thin Driver Support for Data Encryption and Integrity

Hello JDev Team,
I am trying to implement JDBC Thin Driver Support for Data Encryption and Integrity.
It works fine with java.sql.Connection and java.util.Properties like in the following code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Properties props = new Properties();
int level = AnoServices.REQUIRED;
props.put("oracle.net.encryption_client", Service.getLevelString(level));
props.put("oracle.net.encryption_types_client", "( RC4_40 )");
props.put("oracle.net.crypto_checksum_client",Service.getLevelString(level));
props.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@localhost:1521:main", props);
etc...
But I am developing an application with InfoSwing components and it has a different way to connect to Oracle database using oracle.dacf.dataset.connections.Connection, like this:
sessionInfo1.setAppModuleInfo(new ModuleInfo("bc", "BcModule"));
sessionInfo1.setConnectionInfo(new LocalConnection("JDBCThin"));
sessionInfo1.publishSession();
My question is:
Is there any way to implement DataEncryption and Integrity into this type of connection?
Thanks a lot in advance.
Victor Bykov

Victor,
No, you can't do this from DAC, but I've been discussing it with the developer, and we both think this capability would be useful to have, so I've logged it as an enhancement request.
I do have a question for you. Once you've made the JDBC connection, do you need access to the Connection object afterwards? We're thinking of how the change could be implemented, and one way would be to allow you to pass in a Properties object when creating your own NamedConnection.
Thanks
Blaise

Too many options for cut, copy and paste

I have recently removed version 29 which was installed without my permission and reverted to version 28, which was FAR better. I now have a number of right click options for highlight, cut, copy and paste from web pages. I don't see anywhere to attach screenshots but I have FOUR of them, all showing different options for highlight, cut, copy or paste and they are all ridiculous. What can I do to resolve this?
Cheers.
OK. Screenshots added.
1) Dozens of options, of which only cut, copy, paste are needed for the highlighted text. The text is not a video, is not an audio file, is not a plugin, stupid to set as desktop, cannot be deleted.
2) Highlighted text is NOT a link.
3) Duh. No idea what this right click option is about.
4) This is the only right click option I want. Unfortunately, it only appears about once in fifty right clicks.

Do you mean names and passwords in the Password Manager or do you mean that you are no longer logged on to (remembered by) websites after closing and restarting Firefox?
There is a difference between remembering the name and password in the Password Manager and a "remember me" check box on a web page to log you in automatically.
The latter usually involves the creation of a special "remember me" cookie that is stored on your computer and that is send to the server.
If this "remember me" cookie is removed or gets corrupted or is not send to the server then the server won't remember you and you will have to sign in once again.
Details like websites remembering you (log you in automatically) are stored in a cookie.
*Create a cookie 'allow' exception to keep such cookies, especially in case of secure websites and when cookies expire when Firefox is closed.
*Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions
