What is the use of security pathces or cpu patches?

Hi
All,
What is the use of security pathces or cpu patches?
Thanks,
Vishal

Basically, Security patches keep your system secure from known expoits which could compromise your database should someone try to hack it. You don't have to put these patches on but you do need to assess the risk of not patching by checking what the security patch patches and deciding whether you are exposed or not. If you are unsure, then I'd recommend you patch.
CPU patches are Critical Patch Updates that are issued quarterly. These are a mix of security patches and bug fixes. The same applies - you don't have to patch but it is worth taking a look at what is patch and making some assessment of how exposed you might be if you don't.
Be warned, though. If you hit a problem and need Oracle's help, then Oracle support may insist that you are patched to the latest patchsets before they will assit with your issue (assuming the patch doesn't fix the issue).
One word of advice would be that if you do decide to patch, patch your test environment first and make sure everything works normally afterwards, just in case the patch introduces a new issue for your environment - this is rare but I have seen it happen.
Cheers,
R

What is the use of Withholding tax identification number field?

Hello SAP Experts,
I posted this question earlier but had to close because of no replies from anybody. Posting it again to see if I am lucky to get some answer this time.
Can someone tell what is the use of field Withholding Tax Identification Number? Does it help with the reporting? Where does it get populated on the report if given at vendor or master record or within the withholding tax customization for company code? What is the difference between creating it in the customization for withholding tax information for company code and vendor/customer master record?
As per SAP: Withholding tax identification number
This is a number issued by the tax authorities per withholding tax type.
This number must be specified in Customizing either:
(a) As part of the withholding tax information defined for the company code, or
(b) As part of the withholding tax information defined in the customer or vendor master record.

Hi Pete,
The only thing that I could check is the content used in US:
See content of this field for US:
LFA1-STCD1 Social security number
LFA1-STCD2 Employer identification number
LFBW-WT_WTSTCD Withholding tax identification number for WT Type
In order to populate it, please kindly check the following:
The reason why you cannot fill in the field WT_WTSTCD in transaction
Fk02 however you can do it in XK02 (Change vendor centrally) can be due
to wrong customizing of the field status group.
Kindly check the following:
SPRO->
Finantial accounting -> Accounts receivable and accounts payable ->
Define screen layout per activity (vendors) -> Change Vendor(Accounting)
Company code data -> W/holding tax data, w/h tax 2 ->
FIELD Withholding tax code,w/h tax 2 will be probably just available to
display. Please, change it to optional entry.
I hope I could be of assistance.
Kind Regards,

What is the use of HTTPS 8181 port

Hi,
I am wondering what is the use of the port 8181 on the EE5 application server.
the second question. Why the application server open so many port on the same local machine. I agree that for security raison it is a good idea. But does application serveur use tcp connection to communicate between the server thread ?
So it is possible to add a thread in the serveur application to process some internal work. And of course it is possible to include this new thread in the communication process of the server ?
Can we have the map of all the tcp trhead use by the server application.
Regards
Herve Terrolle.

Your app has to run as root to listen on ports up to 1024,
also, some other app (apache?) may already be listening on port 443.
AFAICT port 8181 is just arbitrarily chosen, it might as well have been port 4430, or any other free port above 1024.

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....

... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.

I have a Mac late 06 with lion and want to know what is the best protection/security to get, Mc Fee, or Norton,or...

None of the above.
Norton in particular is anathema.
You have Apple's Xprotect system built-in. malware definitions are updated at each Security Update.
If you feel the need for belt & braces, ClamXAV is the (free) tool of choice.
Your best security is still the stuff between your ears. Don't click on pop-up links telling you need a new codec or (especially) Flash Player. Use your common sense and you'll stay ahead of the industry.

What is the use of SYSAUX Tablespace in Oracle 10G

Dear Experts,
Please Tell me What is the use of SYSAUX Tablespace in Oracle 10G Because
during Web Load Testing It is going to increase countinuosly.Although i am not using this with any tables.
How Can I find out the what is gong on in this.
Can I Remove this tablesspace and other non using Schemas like FLOWS_020100,MDSYS,OUTLN,DIP and TSMSYS etc.

What is SYSAUX?
The SYSAUX tablespace provides storage of non-sys-related tables and indexes that traditionally were placed in the SYSTEM tablespace. For example, the tables and indexes that were previously owned by the system user can now be specified for a SYSAUX tablespace. Unfortunately, Oracle still places the SCOTT schema and the other demonstration schemas in the SYSTEM tablespace. Go figure.
The SYSAUX tablespace is specified with the CREATE DATABASE command. This is demonstrated in the example database creation script in Figure 1.1.
CREATE DATABASE test
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 3
MAXDATAFILES 100
DATAFILE '/usr/oracle/OraHome1/oradata/aultdb1/test/system01.dbf' SIZE 300M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL
SYSAUX DATAFILE '/usr/oracle/OraHome1/oradata/aultdb1/test/sysaux01.dbf' SIZE 120M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED
DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE '/usr/oracle/OraHome1/oradata/aultdb1/test/temp01.dbf' SIZE 20M REUSE AUTOEXTEND ON NEXT 640K MAXSIZE UNLIMITED EXTENT MANAGEMENT LOCAL
UNDO TABLESPACE "UNDOTBS1" DATAFILE '/usr/oracle/OraHome1/oradata/aultdb1/test/undotbs01.dbf' SIZE 200M REUSE AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED
CHARACTER SET WE8ISO8859P1
NATIONAL CHARACTER SET AL16UTF16
LOGFILE GROUP 1 ('/usr/oracle/OraHome1/oradata/aultdb1/test/redo01.log') SIZE 10240K,
GROUP 2 ('/usr/oracle/OraHome1/oradata/aultdb1/test/redo02.log') SIZE 10240K,
GROUP 3 ('/usr/oracle/OraHome1/oradata/aultdb1/test/redo03.log') SIZE 10240K
USER SYS IDENTIFIED BY "password" USER SYSTEM IDENTIFIED BY "password";
Oracle10g sysaux
With the new SYSAUX tablespace, Oracle comes closer to providing all the needed tablespaces for a truly OFA-compliant database right out of the box. With just one CREATE DATABASE command we can specify the SYSTEM tablespace, the TEMPORARY tablespace, the AUXSYS tablespace, the default UNDO tablespace, and the redo logs.
Of course, with the Oracle Managed Files option you can create an entire database with a single command, but the database created is not suitable for production use and is not OFA-compliant.
The SYSAUX tablespace is required in all new 10g databases. Only the SYSAUX tablespace datafile location is specified. Oracle specifies the remainder of the tablespace properties including:
online
permanent
read write
extent managment local
segment space management auto
If a datafile is specified for the SYSTEM tablespace, then one must be specified for the SYSAUX tablespace as well. If one is not specified, then the CREATE DATABASE command will fail. The only exception is for an Oracle Managed File system.
During any update of a database to Oracle Database 10g, a SYSAUX tablespace must be created or the upgrade will fail. The SYSAUX tablespace has the same security profile as the SYSTEM tablespace. However, loss of the SYSAUX tablespace will not result in a database crash, only the functional loss of the schemas it contains.
Can I drop SysAux?
DROP DATAFILE

What is the use of constraint option in Prompt

Hi all,
what is the use of constraint option in prompt.If which scenario it is useful.
pls give the clear explanation.
Regards
bharath

NB -- I am doing this from memory, but isn't the Constraint (or limits in EAS' HBRs) just a way to reduce member selection scope even beyond security?
I think I have used this once as I generally design apps to rely on Planning member security and not add in an extra layer.

what is the best home security cam that works with an iPhone 6

Ignore RichmondDan, he is not a moderator here.
Your question is far too broad. This is like asking what is the best car that works with the iPhone. You might want to narrow your choices to a smaller number of devices, like 3, by using Google or other sites and then ask here again if anyone has used any of these with an iPhone 6 and how well they work and if they have had technical issues. This would be a technical issue and there are lots of similar ones here such as what stylus people recommend, which AirPrint printer, etc.

What is the use of this form?

Hi all,
What is the use of this form in include RV61B901?
How does this code send any information to the program calling it? Is Sy-subrc global so that main program will know the reuslts?
Code:
FORM KOBED_901.
DATA : l_anzpk LIKE likp-anzpk.
SELECT SINGLE anzpk FROM likp
                      INTO l_anzpk
                      WHERE vbeln = komkbv2-vbeln.
IF l_anzpk NE 0.
    sy-subrc = 4.
    exit.
ENDIF.
sy-subrc = 0.
ENDFORM.
Thanks,
Charles.

Hello,
This form sets the value of sy-subrc(which is global) based
on the value of l_anzpk.

What is the use of additon in up to 1 rows in SELECT statement

Hi All,
         What is the use of up to 1 rows in select statement.
for example
SELECT kostl
      FROM pa0001
      INTO y_lv_kostl UP TO 1 ROWS
      WHERE pernr EQ pernr
      AND endda GE sy-datum.
    ENDSELECT.
I'm unable to get in wat situations we hav to add up to 1 rows
please help me out...
Thanks,
santosh.

Hi,
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.

What is the use of Alternative Calculation Type =2 and 4

Dear Friends
In pricing procedure in gross value, Net value for Item and Net value has Alternative calucation type is 2.
What is the use of it?
Without using it these value line are also fetching net value then what is the work of it. Please give me detail information with its effects in pricing condition tab page in sales document.
Thanking You
Arun

Arun biswal,
Correct Biswal. We have at varoius stages within Pricing procedure the "net value" which is calculated. Not only the alternative calculation type "2" is used if you notice carefully they are stored as subtotals at various levels.
For Ex Gross Value --> Subtotal =1 --> Calc type = 2
similarly for Net value for Item --> Subtotal =2 --> Calc type = 2
Net value 2 --> Subtotal =3 --> Calc type = 2
See, these are used to calculate the net value at various levels in pricing. The calculation Type has got a set of routines that will facilitate us in pricing. SAP has provided certain clauclated formulas or routines to facilitate us during calculation within pricing . Here the "2" is used for calculation without tax and store it as subtotal and display it or use it for further calculations.
We can use this "netvalue" amount for further calculations. It is used for clarity purpose when you issue a statement to customer. (like Confirmation order) at various levels like discount amt involved, Freight involved, Rebate amount invloved.....
Even without this Calc type or using sub total u can proceed....
Finally we have TOTAL --> Subtotal =A --> Calc type = 4
In the above line we have Calc type as 4, which means when you use TAX this calc type is used .
Routines are used to facilitate your process....

Sathya
