I have a huge table (about 60 gb) partition over range. The index on this table is global index created on 4 columns together. I have a query which is running very slowly. The explain plan is showing the use of this global index.Explain plan is not showing pstart and pend because the index is global.
I have a partitioned table like below. I want to create a B-Tree index on SALES_RGN column which is neither the part of Primary key or the Partitioned key. Should I create this index as local or Global ?
CREATE TABLE sales_dtl ( txn_id number (9), salesman_id number(5), salesman_name varchar2(30), sales_rgn varchar2(10), -----------------------------> This column needs to be indexed sales_amount number(10), sales_date date, constraint pk_sales_dtl primary key (txn_id) [code]....
I am rebuilding some UNUSABLE local index partitions on Oracle 8.1.7.4.0 (64bit) database . The platform is a HPUX machine.
The DDL of the partition table/indexes: ========================= CREATE TABLE TESTME ( INST_NO CHAR(3) NOT NULL, ACCT_NO CHAR(16) NOT NULL, REC_NO CHAR(9) NOT NULL, TRAN_TYPE CHAR(2) DEFAULT ' ', STAT CHAR(2) DEFAULT ' ', [code]...
For partitioned tables (RANGE, LIST types ) what are circumstances when a Global or a Local Index become UNUSABLE ? I was told that in some circumstances where the Indexes become UNUSABLE , not even a SELECT query against the table will work. Is this true ? For partitioned tables with Global Index, the global index will be listed in DBA_INDEXES . Right ?
I got ORA-14074 error says that if you have a MAXVALUE already you will need to either drop the partition that encompasses the MAXVALUE or split partition.So I want to use split partition option through the below statement,
alter table tablename split partition partmax at (XXX) into (partition partXXX, partition partmax);
I am concerned about the existing data in the table will it by any change gets deleted, and what about indexes, do I have to rebuild, etc.I have to do this on produciton. I cannot test this as I don't have a test environment and moreover the table is having 70 million records and we don't have time/hardware resources to recreate this by export import in another database.
Can i call split partition statement in after insert trigger, my scenario is loader load the data in a table which is not scheduled, the my oracle jobs picks those data for further processing, table which is being loaded by loader is partition and want to split the partition just after the data have been loaded.
I am facing the error "ORA-01502: index or partition of such index is in unusable state " while loading the text data using sql loader with direct path (direct = Y ,rows = 10000) option. Table consists an composite non unique index. If I query the dba indexes for the effected index it shows the index status as VALID. There was no maintaince done on the effected table or index. I have tried loading the same data using conventional path but didn't found any issues for the same.
I have created a table below, my TL asked me to create a local unique constraint for the below table.
I went through all sites and could not find the correct solution, how to create LOCAL UNIQUE CONSTRAINT ON SUB PARTITION TABLE and LOCAL UNIQUE INDEX ON PARTITION TABLE. Creating Local Unique constraint should take care of creating local unique index creation.
Unique key columns are DET,GDS,ARRIVE_DT
CREATE TABLE SUB_PAR_TAB ( ID VARCHAR2(100) NOT NULL, REGION VARCHAR2(40) NOT NULL, SOURCE VARCHAR2(80) NOT NULL, DET VARCHAR2(80) NOT NULL, GDS VARCHAR2(40) NOT NULL, ARRIVE_DTDATE, SYS_SOURCE VARCHAR2(25) , [code]........
I am trying to use Global temporary tables, and index on this table to get my results faster. I can see even if I run any query on this table, it does full table scan and not Index scan..
create global temporary table abc_tab on commit preserve rows as select a,b,c from xyz;
I Have created a interval partitioned table with local index.But when automatic partitions are created based record insertion, whether local indexes will be created for each newly created partition or not? If created, how to check
Below is the code which I tried
CREATE TABLE interval_date ( date1 date, days VARCHAR2(50) ) PARTITION BY RANGE(date1) INTERVAL (NUMTODSINTERVAL(45,'DAY'))
2day i was dropping few unwanted index from the data base, By mistake i removed the local partitioned index , So i want to recreate that index.i create the index, will the partitioned index updates when we add partitioned to the tables.
I have a partioned (by row_create_date) table, lets called it TABLE_X, which has about 300 million records. This table has 7 columns including the primary key and a non-unique, locally partitioned column called trace_id; 99% of queries access this table via this column.
Lately, querying TABLE_X via the trace_id has been very very bad. Queries run for over 1 hr in some cases. So we decided to change the index for trace_id to a global index. Now queries against TABLE_X return in seconds. So far so good.
However, when the query has to join TABLE_X to another table, the query sometimes runs for over 1 hours; back to the same old problem. Here is an illustration;
SELECT COUNT(1) FROM TABLE_X WHERE TRACE_ID = 'XXXXX'; -- returns in seconds SELECT COUNT(1) FROM TABLE_X, TABLE_Y WHERE TABLE_X.TRACE_ID = 'XXXXX' AND TABLE_X.TRACE_D = TABLE_Y.TRACE_ID;
-- runs for over 1 hr, even when TABLE_Y.TRACE_ID is a primary key.
I have table with 4 partition by range partition. I am loading the table in bulk mode to latest partition. Before I load , I dropped the index and after Load I will be creating index. So when I am dropping index, it is dropping index from all the partitions and when creating the index, I am creating the index for all partitions. When I am creating index using local, it is telling you have to create local index for all partitions at the same time. because of that I have to drop and recreate all indexes again. Again I have to gather stats for whole table .
I was thinking we can build index for one partition and index should remain as is for old partitions If this is not the case, how do I plan my load for a partitioned table using bulk mode to latest partition.
I have a table which if approc 5GB in size.I am trying to create a partition table from it. I created the new table,but when i am creating local indexes, i am getting an error when i create a unique key. I ll post the creation scripts:
CREATE TABLE A_PT_ORDREG ( BUS_UNIT VARCHAR2(5) NOT NULL, ORDER_NO VARCHAR2(15) NOT NULL, PT_CODE VARCHAR2(15) NOT NULL, REG_NO VARCHAR2(15) NOT NULL, AS_APPLICATION VARCHAR2(5) NOT NULL,
[code].....
THE INDEX:
CREATE UNIQUE INDEX PK_A_PT_ORDREG ON A_PT_ORDREG (BUS_UNIT, ORDER_NO, SEQ_NO) local;
I am getting the following error:
ORA-14039: partitioning columns must form a subset of key columns of a UNIQUE index
how data is distributed on a local non prefixed index.Let's say I have a table calles SALES and it holds data for the last year partitioned by a date column called month (So that's 12 partitions, one for each month).Now i'm creating the following index: CREATE INDEX TESTIDX ON SALES(salesman_id) local; What will happen is that I'll have 12 partitions on the index but to which partitions in the table are they referencing ?
how to partition and index my table for a special problem.
The table:
CREATE TABLE TEST ( ID NUMBER PRIMARY KEY, U_VALUE NUMBER NOT NULL, -- Ranges from 0 - 30.000.000 O_VALUE NUMBER NOT NULL, -- Ranges from U_VALUE - 30.000.000 CREATE_TS TIMESTAMP DEFAULT SYSTIMESTAMP NOT NULL, UPDATE_TS TIMESTAMP NOT NULL, ITEM_TYPE NUMBER NOT NULL --<< Only 4 different values >> );
As you can see, U_VALUE is ALWAYS lower than O_VALUE.I need to have the CREATE_TS in either main- or subpartition do drop the partitions after some time so i don,t have to use DELETE statements. The table has 360 millions rows.
The application has only 8 query which will always use a WHERE clause like this:
SELECT * FROM TEST WHERE U_VALUE <= :1 AND O_VALUE => :2 AND ITEM_TYPE = :3
1. Is there any good technique how to create a good index for the queries (application will execute 120 queries per second)?
Index with following PARTITIONS. Index rebuild is extremely slow. Below 2 Alter index ..rebuild... took 10 hours to complete. Because of this queries which based on this index are really slow.
SYS@DB AS SYSDBA> select partition_name,tablespace_name,bytes/1024 KB from dba_segments where segment_name='KSTN'; PARTITION_NAME TABLESPACE_NAME KB ------------------------------ ------------------------------ ---------- REB_IDX_1 TS_REB 64 REB_IDX_2 TS_REB 64 REB_IDX_3 INDEX 64 REB_IDX_4 TS_REB 64
Is there any rule in documentation, when create partition index? For tables, it is said to partition when table is greater than 2GB, but what about index? WHat size it should have to partition?
after merging two partitions into single partition (partition is by list) of a table ,when i analyzed the table it is giving this error : ORA-01502 INDEX TEST.PK_ID or partition of such index is in unusable state.
We have a large customer table so first thought was to partition.Also we see two union alls in the plan - can we introduce parallelism? Below is the plan - have attached a text file if difficult to read
