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 references created for a given object ??

How to find the number of references created for a given object in a big application environment.
That means, if i give any object name (of my application) as input, then how can i find the[b] number of references created for that particular object ??

Please do not post the same question multiple times.
As for your original question, there is no direct way to do it.
Especially not the way you phrased it,
since objects don't have "names".
Applications also don't have "names".
They have classes and instances.
Also, there are 2 related issues, and I'm not sure which one is the one you asked.
#1. Finding the number of references to the same object.
Eg.
Map<String,String> a = new HashMap<String,String>();
Map<String,String> b = new HashMap<String,String>();
Map<String,String> c = a;In this case, there are only 2 objects.
The first object has (at least) 2 references pointing to it.
The second object has (at least) 1 reference pointing to it.
(There may be more, if the HashMap library keeps
references to these things, or if the HashMap object has
some internal cyclic references...)
If you're asking this, then it can't be done.
It's an active research topic in universities
and software research labs, called "alias analysis".
Type it in google, and you'll see people are working hard
and having little success so far.
#2. Finding the number of instances created from a class.
In this case, what you have to do is to add a counter to
the constructor of the class. Every time an object is constructed,
you increment the counter. Like this:
   class MyClass
       public static int counter = 0;
       public MyClass( ) { counter++; }
    // Then later in your program, you can do this:
    MyClass a = new MyClass();
    MyClass b = new MyClass();
    System.out.println(MyClass.counter); // It should show 2Note: you won't be able to do this to every class in the system.
For every class you care about, you have to modify its constructor.
Also: when an object is deleted, you won't always know it
(and thus you won't always be able to decrement the counter).
Finalizers cannot always work (read Joshua Bloch's
"Effective Java" book if you don't believe me), but basically
(1) finalizers will not always be called, and
(2) finalizers can sometimes cause objects to not be deleted,
and thus the JVM will run out of memory and crash

How to find the count of tables going for fts(full table scan in oracle 10g

HI
how to find the count of tables going for fts(full table scan) in oracle 10g
regards

Hi,
Why do you want to 'find' those tables?
Do you want to 'avoid FTS' on those tables?
You provide little information here. (Perhaps you just migrated from 9i and having problems with certain queries now?)
FTS is sometimes the fastest way to retrieve data, and sometimes an index scan is.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:9422487749968
There's no 'FTS view' available, if you want to know what happens on your DB you need, like Anand already said, to trace sessions that 'worry you'.

"url two" is not configured to access from external network(internet). only configured for for internal network.
I have configured for scom monitoring for the above two urls using the SCOM 2007 R2 web application template. After configuration i have not received any alert from the "Url Two"
Q1). I am expecting an alert for "Url two" because it is not configured for external network access.
why i was not received any alert for that.
Q2). How to find an web Url alert is raised for internal network or external network. SCOM Tool is not asked me to specify that the weburl is is from internal/external network access.
Q3). Particularly how to find the Url alert was raised for external network
please suggest me and correct me if i am wrong.
Thanks in advance.

Hi,
Its all depends on the settings has done for transaction ST03N.
If it has explicitly set to last 6 months then you can find in the left hand side transaction profile coloumn of ST03N.
If not you can set it by the following way:

How to get Maximum Number of Concurrent users for last few days?

Hi,
How I can get maximum number of concurrent users which were logged in to the system (ECC 5.0) I mean I want to check the hostory for last few weeks. Is there any way to get the same? I know that I can get Cumulative number of users in st03 under Expert mode but that is the number of users logged into the system during the day. Is there any place where SAP maintians the High Watermark of Number of concurrent users reached in the system?
Thanks in advance...
Regards,
Pravin

Sorry I really missed that I have posted a question here on sdn. I wanted to know this for planning the system hardware requirements. Activities like PM ( Performance Management ) happens once a year and during that activity we see heavy user loan on the system so if I have the exact stats of 1 or 2 years data I can size the system better next time. Fortunately last 2 years PM was very smooth for us. In that look for the improvement because each time we had little extra Harware. By doing the exact analysis we can save a Cost of ownership...
I was looking for R/3 users. I could see the number in st07 but I want to know the exact number at particular time.. I believe that st07 stores only for few days.
Thanks

Does it harm the battery if the macbook stays turned off for a few months?

I might be in a situation where I will not use my macbook for a few months. A family member may use it occasionally, but it would be turned off most of the time. Does this hurt the battery or other aspects of computer performance?

From the User Manual: "Storing your MacBook If you are going to store your MacBook for an extended period of time, keep it in a cool location (ideally, 71° F or 22° C) and discharge the battery to 50 percent. When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from your MacBook. To maintain the capacity of the battery, recharge the battery to 50 percent every six months or so."

How to find the worst cluf having indexes? on 10gR2

If the clustering factor(dba_index.clustering_factor) value is close to number of rows of the related table(dba_table.num_rows) this shows bad clustering_factor(CLUF) where as if CLUF is close to the number of blocks of that related table than this shows good CLUF.
So how may I find the indexes having the worst CLUF valuse in my database. Looking for an SQL operator which produces this "close to" output;
create table tdba_indexes nologging parallel 4 pctused 99 pctfree 1 as
SELECT t2.owner, t2.table_name, index_name, clustering_factor, t2.num_rows, t2.blocks, t2.sample_size
FROM dba_indexes t1, dba_tables t2
WHERE clustering_factor > 0
   AND t1.owner NOT IN ('SYS', 'SYSTEM')
   AND t2.owner NOT IN ('SYS', 'SYSTEM')
   and t1.owner = t2.owner
   and t1.table_name = t2.table_name
   AND t2.blocks > 0
ORDER BY clustering_factor DESC ;
create table tcluf_bad nologging parallel 4 pctused 99 pctfree 1 as
SELECT *
FROM (SELECT CASE
                  WHEN a_sql_operator_needed_here_for_close_to_determination THEN
                   'BAD'
                  ELSE
                   'NOT SO BAD'
               END AS "CLUF",
               abs(clustering_factor / num_rows) ratio1,
               abs(clustering_factor / blocks) ratio2,
               t.*
          FROM tdba_indexes t)
WHERE cluf = 'BAD' ;Thank you.

John thank you for your comments. You are right, making structural changes on a table(like CTAS with ORDER BY parallel to the bad CLUF indexes' columns sort) may introduce new problems for other queries involved with other indexes.
This is not a good approach after all. What I am trying is to reduce he high db file sequntial read waits on my CRM database.
http://www.perfvision.com/wait/db_file_sequential_read.html
My primary focus must be SQL and Application tuning to reduce the logical i/o amounts of these queries which are the root cause of this wait. But also I saw that these queries have high CLUF values and doing INDEX RANGE SCAN and this kind of a change may also helpful.
In order to find the root cause queries of this wait I am planning to use this query, can I also have your comments on this;
SELECT a.sql_text, t.*
FROM (SELECT tt.*
          FROM (SELECT rownum rn, x.*
                  FROM (SELECT a.sql_text, a.user_io_wait_time, a.executions, a.sql_id
                          FROM v$sqlstats a
                         WHERE user_io_wait_time > 0
                           AND executions > 10

How-To Find the R/3 Table Name for a BW Data Source

Hi there,
Please advice how can I find the respective table name in R/3 for a particular BW DataSource ?
P/S : I would like a technical how-to instead of referring the table names at HELP.SAP.COM
For instance, for my Standard Business Content Info Cube 0CCA_C03(CO-OM-CCA: Statistical Key Figures) which extracts from BW Data Source: 0CO_OM_CCA_4
My question is, how can I find out which specific tables in SAP R/3 is this Data Source pulling the data from ?

Hi Dinesh,
   Data Source: 0CO_OM_CCA_4
   1) In my R/3, I ran SE16 : Table -> ROOSOURCE
   2) OLTPSOURCE -> 0CO_OM_CCA_4
   3) EXMETHOD = F1
     (Hence, I assume the Extraction Method is a Function Module)
   4) So, Function Module = BWOM_RS_GET_CTRSTA
   5) Run SE37 in R/3
      How do I find out the specific tables in this Function Module ?
      Would you please list them for me, so I can further refer to the individual tables ?
