I want to create primary key on this table that will use the local partitioned index idx_mypart
can I do that ?
alter table mypart add constraint pk_mypart primary key using index (idx_mypart)
above syntax gives error
basically the primary key should make use of the local partitioned index.

SQL & PL/SQL :: Primary And Foreign Key On Same Column And Foreign Key Index
Aug 25, 2010Create table Car
(Car_cd VARCHAR2(5),
Car_Desc VARCHAR2(50)
);
alter table Car
add constraint Car_PK primary key (Car_CD);
INSERT INTO Car (Car_Cd, Car_Desc) VALUES ('CORLA','COROLLA');
Commit;
[code]....
The requirement necessitates a new table to map car to manufacturer. This mapping table may later be expanded to contain other attributes Engine, MPG, etc to hold details specific to a car.But this is in future.
Create Table Car_Mapping_Details
(Car_Cd VARCHAR2(5),
Manufacturer_Cd VARCHAR2(5));
--Primary Key Constraint
ALTER TABLE Car_Mapping_Details
ADD CONSTRAINT Car_Mapping_Details_pk PRIMARY KEY (Car_Cd );
--Not able to create this as Car_cd is already a PK in this table and therefore has Unique Index
ALTER TABLE Car_Mapping_Details ADD CONSTRAINT Car_Mapping_Details_fk1
FOREIGN KEY (Car_Cd)REFERENCES Car (Car_Cd);
[code]....
But in this case the Car_Mapping_Details.Car_cd is itself is a primary key and therefore has Unique index.Although I was able to create foreign key constraint on Car_mapping_details.car_cd column (which is also Primary Key), I was not able to create Foreign Key Index on this column. It gives me Quote:ORA-01408: such column list already indexed.In other words, not creating foreign index for foreign key column lead to table-level lock? Or will the Unique Index in that primary key column be sufficient to avoid table-level lock?

SQL View Showing Non-related Records?
Jun 27, 2011I'm trying to get a list of values from a table, and I am just not seeing the answer -I have a table with 4 records (say A, B, C, and D), each record has a GUID to uniquely identify it.I have a 2nd table that holds the relationships (parent-child).
At this point, I have 2 rows:
A>B
A>C
So, A is a parent to B, and A is a parent to C (D is not related to anything at this point)
I would like to be able to go into the D record and see that it is NOT related to A (A would be the parent in this instance) - the trick however is I only want 1 instance of A to show up.attempted to use some inner/outer join qualifications and I just cannot seem to get the data to display properly.
SQL & PL/SQL :: Retrieving Related Records As Groups
Mar 12, 2008I have a table of N records with: Name SeqNo ID Col4 ... ColX
where Name and ID are non-unique, and SeqNo is a monotonic non-consecutive sequence 0 .. N that is unique within ID..I'd like to generate the following 'groups': For each record where SeqNo = 0, sorted by Name, create the 'group where ID is the same, ordered by SeqNo irrespective of the
values of any of the other columns. For instance, if the table contained:
NameSeqNoIDCol4 ... ColX
RPL2975...
TLM0444...
AAB2801...
AZZ0801...
ABA3444...
KTT4975...
ABA1801...
YHG0975...
DEF1444...
I'd like to generate:
NameSeqNoIDCol4 ... ColX
AZZ0801...
ABA1801...
AAB2801...
TLM0444...
DEF1444...
ABA3444...
YHG0975...
RPL2975...
KTT4975...
I got my desired results by brute-forcing via four sub-queries:
Sub-query 1 - Generate the sorted Names with SeqNo = 0
Sub-query 2 - Expand above with the additional columns,
maintaining original order
Sub-query 3 - For each of the records from sub-query 2,
generate the 'dependents' having the same ID
and SeqNo != 0
Sub-query 4 - Expand above with the additional columns,
maintaining original order of sub-query 1
Main query - Create UNION of 2 and 4, sorting by original
order and SeqNo
if there were not a simpler approach - after all, this must be a fairly common issue when generating BOMs.
Replication :: Reorganize One Table That Related To Several Other Tables
May 15, 2009I have to reorganize one table that related to several other tables. The reorg is too slow when it runs on this table. I would like to create one image of the table and synch it with the original one in real time. So when I run the reorg, I will use the image table that does not constrained by indexes and other objects. Once the reorg is done, I would like to rename the table. how could I do the replication in real time?

Server Administration :: Application Related Tablespaces
Oct 31, 2011How to find out the tablespaces specific to application (i.e. not related to oracle like system, sysaux,temp,undo etc..)
View 1 Replies View RelatedServer Administration :: Cannot Start Listener (/tmp Related)
May 9, 2012OS: AIX 6.1 64bit
DB: Oracle 10gR2 (10.2.0.5.0)
What we did is..
1. Install patch 6613550 (./rootpre.sh)
2. Install 10.2.0.1 for AIX 64-bit
3. Install 10.2.0.5 Patch Set
4. Create Database
5. Created/Setup LISTENER and TNSNAMES (test connection successful)
After installation of database, everything went well until we tried to restart the server, what happened is that we cannot start the listener, the error was:
TNS-12555: TNS:permission denied
TNS-12560: TNS:protocol adapter error
TNS-00525: Insufficient privilege for operation
IBM/AIX RISC System/6000 Error: 1: Not owner
What i did to resolve this problem is to change the owner of /tmp to oracle, after that i was able to start the listener. ($lsnrctl start) The problem is that our sys admin said that the /tmp directory is being used by the OS and it's owner must be root. But if i return it to root, the listener will not start again. (After server restart)
BTW, our /tmp has enough space so we did not perform the following steps from the installation guidelines:
$TEMP=/directory
$TMPDIR=/directory
$export TEMP TMPDIR
I was thinking if that we must make a temp directory for oracle and set it in the profile, or change the owner to root again and perform this:
$chown -R oracle:oinstall /tmp
$chmod -R 777 /tmp
Performance Tuning :: PLSQL And Related Cursors Generated In V$sql
Jan 26, 2012I wanted to know how to find the links between cursors that have been created in v$sql after compiling a PLSQL procedure.
For example, if i compile the following procedure :
create or replace
PROCEDURE PROCEDURE1
AS
BEGIN
insert into t values(1,1);
END PROCEDURE1;
, the 2 following cursors are created in v$sql :
select SQL_ID, SQL_TEXT from v$sql
where sql_id in ('71pj8t5nz1d80','2s567zb6684sh');
"SQL_ID""SQL_TEXT"
"2s567zb6684sh""BEGIN PROCEDURE1; END;"
"71pj8t5nz1d80""INSERT INTO T VALUES(1,1)"
Thus, i would like to know how to find that the cursor 71pj8t5nz1d80 is called/linked by the cursor 2s567zb6684sh.
This would be useful for interpreting some sql statistics in v$sqlstats in where such cursors appear and related sql statistics are accounted twice.

View 5 Replies View RelatedPerformance Tuning :: Queries On PGA Settings And Related Memory Management?
Feb 11, 2011I have few queries on PGA memory management.Since these queries are based on 2-3 examples not exactly same by nature I am summarising it after my understanding for the same
As I understand many workareas can be allocated to a single sql statement and number and sizes of theses workareas is controlled internally by Oracle when Automatic Memory management (PGA_aggregate_target and workarea_size_policy=Auto are set) Since many sessions share the PGA memory, the amount of memory available to each session may vary and if less amount of memory is available for a session for sorting then TEMP tablespace is used
[1] Can we say paging happens and can be checked at this time?
[2] Is there a difference in handling memory while populating pl/sql tables?
As I have encountered ora-04030 while some our developers were populating pl/sql tables but never encountered this error for sorting, hash joins etc Though I don't remember the width of pl/sql table, I am sure the developer used 'LIMIT' clause during bulk collect and still faced the issue.
With a single session on the server, I noticed that the difference in values displayed issuing 'free' command in linux and output values from sesstat did not match at all while there wasn't any heavy OS process involved during the period. I was expecting 'used' and 'free' values displayed by free command (linux) will change and difference would be approximately equals 'before and after values of session pga memory.
[3] Isn't it expected to match?
[4] Can we say in dedicated server, at any moment of time, the SUM of 'session pga memory' represents all the memory used by Oracle SGA, at that point of time?
select sum(value)/1024/1024 "memory in MB" from v$sesstat where statistic#=20;
During one of the tests I got following output (divide value by 10 for my visibility and avoid formatting)
SQL> select a.name, to_char(b.value/10, '999,999,999') value
from v$statname a, v$mystat b
where a.statistic# = b.statistic#
and a.name like '%ga memory%'; 2 3 4
[code]...
The above query is showing above values even when the pl/sql block execution is completed 30 minutes back
[5] Do we call this as 'memory leak' where memory is not released even while some time has passed since session has done something?Of course I am not checking at OS level as mentioned in question [3] above the values won't match!
Still the output of free command for reference(After the pl/sql block executed)
SQL> !free

[code]...
[6] What could be the significance of negative values of 'session pga memory/max'?
Last We have an OLTP system and in the night we run batch processes in 2-4 sessions
Suppose I have 10 GB RAM and with PGA setting of 3.5 GB Now I want the batch process sessions to use max possible memory during nighttime and toggle the setting back in the morning
[7] With above settings (10 GB RAM and 3.5 GB PGA) how can I divide the memory among 4 sessions?
Shall I set 1) PGA_aggregate_target=0 2)Workarea_size_policy=manual 3) Sort_are_size 4) Hash_area_size
[8] What would be approx values for parameter 3 and 4? will it be straight 3.5 GB/ 4?

I have loaded into an Oracle table defined as XMLTYPE. I'm okay with PL-SQL and stored procedures, where I will ultimately do this processing once I get a handle on XML DB querying from an XMLTYPE table.
Based on reading the oracle documentation about XML DB, and more importantly, reading dozens of posts to this forum,I have been successful in loading the XML files into a SQL XMLTYPE table and doing simple queries against that table to retrieve some of its data so that I can then insert that data into other target oracle relational tables.
how to select parent/child data from XMLTYPE tables. I am able to follow the forum examples and can replicate the methods shown on the many example XML contents shown on this forum, but not against the XML that I have to process. I am wondering if my struggle is caused by my lack of knowledge, or by ill-formed XML content supplied to me by the educational vendor.The XML content has structured the XML content nodes in such a way that I do not seem to be able to apply the parent/child sql methods.I have been able to use for other XML examples I have tested against.
My XML file shown below represents High School Transcript data, for which I need to be able to parse out into my own oracle relational tables for that student, his personal info, and his course info, etc. i.e., for our example, which courses he has taken for which High School grade levels. The vendor-supplied XML seems to put the Courses and the High School grade level in "parallel nodes," instead of parent/child nodes, so I am struggling to be able to use SQL to differentiate which course the student took in NinthGrade versus TenthGrade.
-- WHat I would like to determine from a select statement:
LASTNAME GradeLevel COURSETITLE
=============================
Smith NinthGrade PHYS ED 101
Smith TenthGrade CALCULUS 201
Smith TenthGrade ZOOLOGY 202

View 1 Replies View RelatedText :: Index For Domain Index With Composite Domain Index (CDI) Very Slow
Jun 27, 2012I am on 11.2.0.3 Enterprise Edition. We are using the new feature "Composite Domain Index" for a Domain index on a very large table (>250.000.000 rows). It really works with mixed queries. We added two number columns using FILTER BY.We have lots of DML on this table. Therefore, we are executing synchronize and optimize once the week. The synch behaves pretty normal. But "optimize_index" takes a very very long time to complete. I have switsched on 'logging' for the optimize process. The $I table takes some time but is finished normally. But the optimization of the $S table (that is the table created for the CDI feature) is running over 12 hours now - and far from being finished. From the logfile, I can see that it optimizes 1000 rows every 20 minutes. Here is the output of the logfile:
Oracle Text, 11.2.0.3.0
14:33:05 06/26/12 begin logging
14:33:05 06/26/12 event
14:33:05 06/26/12 process $N for optimize: SEQDEV.GEN_GES_DESCRIPTION_CTX_I
14:33:16 06/26/12
14:33:16 06/26/12

I haven't found a recommendation from Oracle not to use "optimize_index" for Domain Indexes with CDI. But in my case, it would be much faster just to drop and recreate the Domain Index in question.

Performance Tuning :: Index With NVL / Query Is No Longer Using Index
Nov 19, 2010I have a query which had a join:
a.c1=b.c1 and a.c2=@var
where @var is user supplied input at runtime...We had a index on a.c2 . The CBO would use this index to generate an opitimised query plan.We found some records from table "b" were dropping due to inner join. So we made a change in join. It'd be like
a.c1(+)=b.c1 and nvl(a.c2,@var)=@var
This query is no longer using the index, instead its doing a full table scan causing the query to slowdown.I have tried creating index on nvl(a.c2,'31-dec-9999')
But the CBO won't use it.Anyway to create index on this col so that full table scan can be avoided?
