Creating Local partitioned index on Range-Partitioned table.

Hi All,
Database Version: Oracle 8i
OS Platform: Solaris
I need to create Local-Partitioned index on a column in Range-Partitioned table having 8 million records, is there any way to perform it in fastest way.
I think we can use Nologging, Parallel, Unrecoverable options.
But while considering Undo and Redo also mainly time required to perform this activity....Which is the best method ?
Please guide me to perform it in fastest way and also online !!!

Do you think this is the only method to perform operation in fastest way? As table contain 8 million records and its production database.Yasser,
if all partitions should go to the same tablespace then you don't need to specify it for each partition.
In addition you could use the "COMPUTE STATISTICS" clause then you don't need to analyze, if you want to do it only because of the added index.
If you want to do it separately, then analyze only the index. Of course, if you want to analyze the table, too, your approach is fine.
So this is how the statement could look like:
CREATE INDEX CSB_CLIENT_CODE ON CS_BILLING (CLIENT_CODE) TABLESPACE CS_BILLING LOCAL NOLOGGING PARALLEL (DEGREE 14) ONLINE COMPUTE STATISTICS;
If this operation exceeds particular time window....can i kill the process?...What worst will happen if i kill this process?Killing an ONLINE operation is a bit of a mess... You're already quite on the edge (parallel, online, possibly compute statistics) with this statement. The ONLINE operation creates an IOT table to record the changes to the underlying table during the build operation. All these things need to be cleaned up if the operation fails or the process dies/gets killed. This cleanup is supposed to be performed by the SMON process if I remember correctly. I remember that I once ran into trouble in 8i after such an operation failed, may be I got even an ORA-00600 when I tried to access the table afterwards.
It's not unlikely that your 8.1.7.2 makes your worries with this kind of statement, so be prepared.
How much time it may take? (Just to be on safer side)The time it takes to scan the whole table (if the information can't read from another index), the sorting operation, plus writing the segment, plus any wait time due to concurrent DML / locks, plus the time to process the table that holds the changes that were done to the table while building the index.
You can try to run an EXPLAIN PLAN on your create index statement which will give you a cost indication if you're using the cost based optimizer.
Please suggest me if any other way exists to perform in fastest way.Since you will need to sort 8 million rows, if you have sufficient memory you could bump up the SORT_AREA_SIZE for your session temporarily to sort as much as possible in RAM.
-- Use e.g. 100000000 to allow a 100M SORT_AREA_SIZE
ALTER SESSION SET SORT_AREA_SIZE = <something_large>;

How to simply create a locally partitioned index with a dedicated tablespac

Dears,
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64biSuppose you have a range partitioned table t on date d with n partitions p1, p2,....pn
If you create a locally partitioned index using the following script
create index ind_loc on t(d) local;all the partitioned indexes will be created on the same default tablespace.
Is there a simple creation script (not that where we have to add each partition and each tablespace) to use in order to associate each partitioned index to a given tablespace?

Hi Mohamed ,
AFAIK , there is no such script . If you want partition to be stored in different tablespaces, then you will have to specify partition name along with tablespace name in create index command.

Do I need to Create Primary Key Class for Entity beans with Local interface

Do I need to Create Primary Key Class for Entity beans with Local interface?
I have created my entity bean with the wizard in Sun One Studio and it does not create a primary key class for you.
I thought that the primary key class was required. My key is made up of only one field.
Anyone know the answer.
Jim

u dont need to create a primary key class for a entity bean.if ur table's primary key feild(int ,float) is a built in or primitive data type,then u dont need one.But if ur table has a primary key field which is non primitive (for example StudentID,ItemID etc)then u have to create a primary key class.
hope this helps :-)

What is the best practice for creating primary key on fact table?

what is the best practice for primary key on fact table?
1. Using composite key
2. Create a surrogate key
3. No primary key
In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
I also found a relevant thread states that primary key on fact table is necessary.
Primary Key on Fact Table.
But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

Creating Primary Key Index

Hi,
Iam trying to create a Primary Index on Large table and Iam using the Parallelism to make it fast. I have used the following script to create a Primary key Index.
CREATE UNIQUE INDEX FLX_ARCH.FUND_SEC_RESULT_STAT_ARCH_PK
ON FLX_ARCH.FUND_SEC_RESULT_STAT_ARCH
(FUND_SEC_RESULT_MAP_INST,RATES_RULE_ID,BASE_LOCAL_FLAG,EFFECTIVE_DATE)
TABLESPACE FLX_PERF_I
parallel;
Index created.
Elapsed: 01:43:37.37
Index got created in 1 hour 43 minutes. But when Iam adding constarint to those columns, it is taking almost 12hours with or without parallelism.
ALTER TABLE FLX_ARCH.FUND_SEC_RESULT_STAT_ARCH
ADD CONSTRAINT FUND_SEC_RESULT_STAT_ARCH_PK
PRIMARY KEY
(FUND_SEC_RESULT_MAP_INST,RATES_RULE_ID,BASE_LOCAL_FLAG,EFFECTIVE_DATE)
parallel
Would you please let me know what could be the problem and how can we add the Primary constraint fast.
Your early response is much appreciated.
Thanks and Regards
Suresh. D

Would you please let me know what could be the problem and You have presented no details that indicate any problem exists.
how can we add the Primary constraint fast. Fast is relative.
If I asked you to make my snail fast, could you do so?
ALTER SESSION SET SQL_TRACE=TRUE;
ALTER TABLE FLX_ARCH.FUND_SEC_RESULT_STAT_ARCH
ADD CONSTRAINT FUND_SEC_RESULT_STAT_ARCH_PK
PRIMARY KEY
(FUND_SEC_RESULT_MAP_INST,RATES_RULE_ID,BASE_LOCAL_FLAG,EFFECTIVE_DATE)
parallel
ALTER SESSION SET SQL_TRACE=FALSE;
now find the trace file within ./udump folder
tkprof <trace_file.trc> trace_results.txt explain=<username>/<password>
By inspecting the trace file you will be able to see where time is being spent.
With this knowledge, you may or may not be able to determine the bottleneck & therefore improve it

SQL Data Modeler 3.0 EA1 trying to create primary key on OT

Hi,
I'm trying to modify a primary key of an object table that was reversed (imported) from an Oracle 11.2.x RDBMS and am getting the error message "Incomplete Index definition". It is showing in the window "Index Columns Assignment". I get to the 'Primary Key Properties' window by pressing the 'Properties' button on the 'Table Properties' -> 'Primary Key'. If I try to edit the expression and then press the Ok or Apply buttons I get the error. With this be fixed in the production version? Will we be able to create a model in SQL Developer Data Modeler that generates a SQL statement similar to the following:
ALTER TABLE x_flags
ADD (CONSTRAINT x_flags_pk PRIMARY KEY (flags.id))
Thanks,
Scott K

Will we be able to create a model in SQL Developer Data Modeler that generates a SQL statement similar to the following:
ALTER TABLE x_flags
ADD (CONSTRAINT x_flags_pk PRIMARY KEY (flags.id))I assume "flags" is column of object type and "id" is attribute of that type. I logged bug for that, so there will be support however not for 3.0.

How to create Primary key

I want to insert HOSTID that has unique values in a new application in a primary key column in database.
I am starting with h000000001
and I want to go from that to h000000002
and .... h0000000010 , 11, 12 etc etc.
How do I do this?
I did this:
rs = stmt.executeQuery("select wlbmach_host_id from wlbmach order by wlbmach_host_id desc");
// I am getting the greatest value eg: h000999999
if (rs.next())
getHostID = (String)rs.getString("wlbmach_host_id");
//Get the h0009999999
getStringNumber = getHostID.substring(1,10);
//This gives me 9999999
try
{getNum = Integer.parseInt(getStringNumber);
//change number to integer so I can add 1 to it
getNum=getNum+1;
getStringNumber=Integer.toString(getNum);//make that a string
getHostID="h"+getNum;//add h to it
}//try
catch(Exception e)
{System.out.println("NumberFormatException might have occured");%>
else
System.out.println("Assigning first HostID");
getHostID = "h00000001";
System.out.println("HostID is "+getHostID);
But gives Exception:String index out of range: 10.. My column can take 10 varchar ??
Can someone help .. Is this the right way to do it ?
Is there a better way to generate primay keys?

Why are you making life difficult??? Why not use the SEQUENCE object (if you are using Oracle)? You can retrieve next value by "Select sequencename.nextval from dual" as the query...you will get your number. Also, when two requests are made at the same time, Oracle takes care of this problem for you...you do not need to synchronize the method in JAVA. Do some research in this...I think you will like it.

Unable to create primary key

Hi all.
This one I can't handle. Do you guys know where I can find this constraint?
SQL> desc marcos

COD                                                VARCHAR2(40)

Even you don't have bitmap index on it the query will still fail, you had duplicate record in this column :)
COD DSC

2 asdfasfdas
3 asfasklfjd
1 << safasjfasdf

Create Primary key on View?

Hi
Can we create a Primary or Unique key on a simple view? while actual table doesn't have any primary or unique key
Regards,
Nasir.

But what about this Example.
CREATE VIEW emp_sal (emp_id, last_name,
email UNIQUE RELY DISABLE NOVALIDATE,
STRAINT id_pk PRIMARY KEY (emp_id) RELY DISABLE
NOVALIDATE)
AS SELECT employee_id, last_name, email FROM
employees;This creates a view and tells Oracle that the optimizer is free to rely on email and emp_id being unique but that your code will enforce both constraints. Since you know that your data violates these constraints, that basically means that you're lying to the optimizer and allowing it to make incorrect assumptions about the data. That, in turn, permits the optimizer to either generate incorrect query plans or deliver you incorrect data should it happen to rely incorrectly on one of these constraints. Realistically, this sort of view would take an existing data quality issue and layer on a bunch of optimizer issues rather than addressing the root cause and fixing the data.

Creating primary key dynamically ?

hi
I have say table t1 which has pk constraint say pk1 using say 4 columns c1,c2,c3,c4 in database1.
I need to create same pk constraint with same parameters and name on same table t1 which is into another database.
I need a generic function / proc to do this as the tables can change and so as number of columns used in the primary key constraint .
How do I go about this ?

I need a generic function / proc If I may say so, this is completely the wrong way to manage change in the database. What you really need is a configuration management procedure that checks change scripts into a source control repository and makes sure they get run against all the affected databases.
