How to find the 1(one week) performance of the system

HI every one
in my recent interview he has asked this question
i have checked the sar options through man pages but i couldnt understand ...
can any one please tell me how to find the on week performance report of a system......
please tell me how i can find the performnace reports
Thanks in Advance

Hi.
crontab -l sys
Show, activated or not collecting of performance statistics.
man sa1
The shell script sa1, a variant of sadc, is used to collect
and store data in the binary file /var/adm/sa/sadd, where dd
is the current day.
So you need found file with correct date in /var/adm/sa

How to find the system default scripts and prompts in UCCX 8.0

Hello everyone,
I have a bit of experience in UCCX 6.0 and just began to use UCCX 8.0. There's a question that where can I find the system default scripts and prompts in 8.0? In 6.0, I can find them in installing directory, but 8.0 is linux based so I can not do that in same way.
Thanks.

You can Login to CLI with either root access or remote user access and get default scripts by going to
CD /opt/cisco/uccx/Scripts/system/default
At this point you have to connect to ftp server and move these default script to yoru FTP server.
I hope this helps

How to find the system's proxy settings programatically

Hi,
I am creating a ABAP class which acts as a HTTP client and thus I use the standard object "call method cl_http_client=>create_by_url". This method takes the proxy host and proxy port as input and i want to know how can I find the proxy settings of my system programatically so that I do not ask customers to add these values as configurations for my code.
Is there any standard API in ABAP to find this information?

: How to find the system(machine) in the domain (network)

Hi Everybody,
Can some tell me how can i find the machines(system's computer's ip address)that are their in the network.
Iam developing a small program in Java, which i want to know the m/c's that are there in the network (or domain).
well anything even with ntive program that gives me all the ip's or m/c name as return will do.
Thanks in Advance.
Amit

I have not tried this in java, but the theory is the following:
In IP: if you want to receive response from all machines in your network, you would do the following:
(I will take a class C network as example)
Network: 192.168.1.0
Ping 192.168.1.255 (this is the broadcast address).
This way, all machines should respond. I think it is the ICMP protocol you use to do this.
The other solution (not Ethernet, and I think impossible with java) is to make a layer 2 (data link layer) broadcast rather than a IP (layer 3) broadcast. This can be done with a special MAC address code used to broadcast.
However, the first method should work for you, now the big question. How to use ICMP in java?

I reformated my computer to sell and now I cannot figure out how to find the system info and specs of the computer

I had Apple wipe my computer clean and now it's at the "Welcome" page but I need to find out all the specs like RAM/Hardrive space how can I get that info without running the welcome intro?

if you know the year and CPU speed of this macbook - go to everymac.com and match your specs from the year it was released.
if you can see your serial number - go to the link below and enter the last 3 characters of your serial number and you'll get the specs.

How to find the number of ODBC connections to Oracle Database

Hi All,
How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
Thanks in advance,
Mahi

What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
For example: if you already know of a user using ODBC, you can verify as:
select username, osuser, terminal, program from v$session where username = 'SCOTT'
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
Hope this helps...

How to find the number of records in ods?

how to find the number of records in ods?
Pls suggest the solution apart going to the table of ods and seeing the number of records.
Is there any program or function module to see the number of records in ods?
For eg: SAP_INFOCUBE_DESIGNS is a program which gives the detail (number of records) of infocube.

Hi,
I was looking at this and found the following tables that may be of help.
One of these tables will include a summary of the record count of all the tables in your system based on the last time each table had it's database statistics calculated:
DBSTATTADA
DBSTATTDB2
DBSTATTDB4
DBSTATTDB6
DBSTATTINF
DBSTATTMSS
DBSTATTORA
We run on an Oracle database so the table record counts can be taken from DBSTATTORA. Type in AZ in table selection field in SE16 to restrict the output to ODS (or DSO) tables only.
The record count is at the time indicated in the timestamp field. Obviously this is not real time but should not be too out of date - if it is you may be having performance issues and should get your DBA / Basis to run a full refresh of DB stats.
Hope this helps, alhtough not real time the table should give you a decent indication of the size of all your ODS objects (or any other table for that matter!)

How to find the database growth rate?

Wanted to do the forecasting of disk growth for one year. How to find the database growth rate?
Rahul

This is code authored by Richard Ding that will log database sizes to a table. If you run it every day, then you can go back and compare the database size differences day to day... week to week... month to month... and year over year. That is
how I forecast growth over time.
Note: There is a database name required that is local to your environment, so change [YOURDATABASENAME] to whatever local database you wish to use. I will also post the DDL to create the target table. Create that table in the database you
name in the stored procedure code and all should run fine.

How to find the number of data items in a file written with ArryToFile function?

I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
If you are young work to Learn, not to earn.
Solved!
Go to Solution.

What about:
OpenFile ( your file );
cnt = 0;
while ((br = ReadLine ( ... )) != -2) {
if (br == -1) {
// I/O error: handle it!
break;
cnt++;
CloseFile ( ... );
There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
Proud to use LW/CVI from 3.1 on.

How to find the number of links in a website

hi every body
can any one clear my doubt
my doubt is that
in a website how to find the number of links the hole website contains
is there any navigation tool to find that
plz help me yar
i am waiting for the reply

If you're talking about commercial sites (sites you don't have the source code for) I'm not sure.
If you want to count the links in site that you have the source code for, it should be relatively easy to write a Java application to do it. All you really need to do is have a list of the files you want to count links in, read each file line by line and check for the existance of the <a> tag in each line. Anywhere their is an <a> tag there is a link.
Hope this helps.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.
