How to decide how many number of col in a table can be made keeping 8kb lenght to speed up.

hi,
I am making one big table which will have good no of cols,
There is one critaria that is, to seepd up keep the lengh of row less than 8 kb pages(now it has been raised).
Q1)please tel me ,in this critaria ,collenght is checked or datalenght is checked , because i know that my col length will exceed 8 kb but data will never exceed , it is rare, may be few rows may exceed.
yours sincerley.

It is unclear what you are trying to achieve? A disk space? In order to speed up the query you need proper;y created indexes...
Calculate numbers of rows that ca fit on an 8K data page
8060/bytes per row= rows per page
Calculate the number of data pages needed
Number of estimated rows / rows per page =data page needed
8192* data pages needed = Total bytes
Total bytes\1024= Total KB

How to Know the How many number of JCo connections established?

Hi
How to Know the How many number of JCo connections established for mapping?

Hi
mConnection = JCO.createClient("001", // SAP client
 "<userid>", // userid
 "****", // password
 null, // language
 "<hostname>", // application server host name
 "00"); // system number
//Connections to a specific application server (as in the above example)
mConnection.connect();
//Creating the JCO.Client object does not connect to SAP, but a subsequent call to
connect() will accomplishes this
So you can easily find out the number of JCo connections by checking out these.
Thanks

Maximum Number of Columns that adf table can support in JDeveloper 10.1.3.1

Hi All,
I'm using Toplink 10.1.3.1 . In JDeveloper 10.1.3.1 .
I'm Trying to display the columns of a table which is having the more than 380 columns.
When I'm trying to display the columns in adf table, it is getting hanged. The console of the displaying that "too long".
If Execute the Application with nearly 50 columns, It is working fine.
what is the Maximum number of columns that adf table can support. Is there any other solution for my problem.
could anyone help me out.
Thanks in advance,
regards,
Satish

Hi,
I am not sure there exist a limitation in columns and if the application hangs then this probably is a bug either in the business service or the view (which can also be due to that the server runs out of memory because of the created object instances).
However, in my opinion a table with 380 columns is a loud cry for denormalization

How many number of pages can be included in a single spool request

Hi ,
How many maximum number of pages can be included in a single spool request. can we increase or decrease these max no of pages per spool in SAP.Please advise.
Thanks & Regards,
Sam.

Hi Sam,
The spool is ultimately a file created in the database. So it can handle a large number of pages.
By defaut it shows only first ten pages.. This can be changed from the settings in SP01.

Counting how many number of elements in a XML

Hi all, 
I am having a requirement in ABAP-IXML ie., i need to find how many times a same element name(ComponentUsage) gets repeat in an xml. 
here is the xml, 
 
<Component mmRelease="6.30" mmVersion="2.0" mmTimestamp="1180099591892" name="Comp_three" package="sap.com" masterLanguage="en"> 
 
<Component.ComponentUsages> 
<ComponentUsage lifecycleControl="createOnDemand" name="comp1"> 
<ComponentUsage.ComponentControllerUsages> 
<ComponentControllerUsage name="Configuration"> 
</ComponentControllerUsage> 
</ComponentUsage.ComponentControllerUsages> 
<ComponentUsage.UsedComponent> 
<Core.Reference package="sap.com" name="Comp_twoInterface" type="ComponentInterfaceImplementation"/> 
</ComponentUsage.UsedComponent> 
</ComponentUsage> 
</Component.ComponentUsages> 
 
<Component.ComponentUsages> 
<ComponentUsage lifecycleControl="createOnDemand" name="comp2"> 
<ComponentUsage.ComponentControllerUsages> 
<ComponentControllerUsage name="Configuration"> 
</ComponentControllerUsage> 
</ComponentUsage.ComponentControllerUsages> 
<ComponentUsage.UsedComponent> 
<Core.Reference package="sap.com" name="Comp_twoInterface" type="ComponentInterfaceImplementation"/> 
</ComponentUsage.UsedComponent> 
</ComponentUsage> 
</Component.ComponentUsages> 
</Component> 
 
Here as the xml is short so i manually knows tat the element "ComponentUsage" are used 2 times, but suppose if i use a big xml and the component usage element is used "N" number of times then how can i count mannually....... so is there any method or code to find how many times does "ComponentUsage" element present in an XML. 
 
Thanks in advance,

Is there a way to know how many rows were rejected using external tables?

Hi,
I'm developing a package that needs to load different kinds of text files into the DB.
I was wondering whether there's a way of knowing in SQL or PL/SQL how many rows were rejected if my external table is defined with "reject limit unlimited".
I'm using the external tables in "insert into ... (select ... from external_table where...)"
sql%rowcount returns the number of inserted rows
I was hoping for something similar/easy to get the number of rejected rows as well.
I know I can try to analyze the bad file for the number of records if there's no other way...
Thanks in advance.

I was afraid of this answer...
this is a certain "no there's no other way" or should i wait for other responses (no disrespect - just want to make sure :) )Well the difference would be that this external table will have no complex logic. You would simple read in all the lines from the bad file. The chances that this is broken are therefore very slim compared with your original external table.
And tehre are many other ways possible. For example you can first copy the file into a real internal (temp) table without using any processing logic but with using an external table. Then do the processing / logic checking of the data and move the data from this temp table into your final data structure. Since you move the data two times the whole process will be slower then the original version.

How many event actions filters a cisco ips can support

we are running cisco ips 7.0(2) E4, and we are planning to tune some of the traffic everyday.......any idea how many event action filters can be applied to a sensor or is there is any maximum limit on the number of filters?

There is no limit to how many event action filters you can configure. I assume that you also know that event action filters is ordered list:
http://www.cisco.com/en/US/docs/security/ips/7.0/configuration/guide/idm/idm_event_action_rules.html#wp2033432
Also, found this bug FYI: bugID: CSCtf78755:
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtf78755
(When over 495 event action filters are configured via CLI, it's corrupting "rules0.xml" file)
Hope that answers your question.

HT5622 How many family members, computers, iPods,iPad,IDs can you have on one iTunes account?

I'm just trying to sort out some iTunes I'd issues. Does anyone know how many total iPad iPods can be used with one Apple ID? Or how many apple IDs your can have with one iTunes account? Or does each person need there own Apple ID or Apple account? Thanks

You can't have multiple IDs on one account, but you can use multiple IDs for different purposes on the same device.
Just use the one AppleID for iTunes and the AppStore so you can all share your music and app purchases. Then each person should have their own individual AppleID with associated iCloud account for mail, contacts, calendars, iMessage and FaceTime.
You don't have to use the same AppleID for all services.

I had set my passcode by pressing 1 repeatedly till it filled the passcode box. I dont know how many times I have pressed 1. Can someone tell me the character length of the text box of the Passcode

Hi,
My son foolishly pressed a single digit till it just filled the text box of the passcode. Now i dont know how many times he has pressed it. If I can know the charcter length, or how many digits can just fill the text box of passcode, I can unlock my ipad2. If anyone reading this has ipad2, he can do the same thing and count how many digits will just fill the text box. I will really appreciate the help.
Thanks

You can put the iPad into Recovery mode and Restore it. See this link and note the sentence commencing, 'If you restore from a different computer.... ' down near the bottom of the page.

Ping response from 1st pair of switches to destination server : normal (between 1 to 3 ms)
Ping response fron 2nd pair of switches to source server :   (jumping from 3ms to 100+ ms).
There is no errors or packet drops on any of the above ports, I cannot understand why the ping response is high for connections from second pair.
