SQL & PL/SQL :: Add Index Enable No Validate
Nov 1, 2011
I have a table, it has 3 terabytes of data. We are sure whatever the data we have in that table is valid. I need to add the index to table it should be enabled and need not to be validated for existing data.
I am using following command
CREATE INDEX U_IXN_MTRS_ORGIDMTRNOMTRTYPEID ON MTRS (nlssort(METERNO), METERTYPEID) TABLESPACE OLTP_IDX_TS ENABLE NOVALIDATE;
it is giving me problem
ORA-02158: invalid CREATE INDEX option error

Is there any way to enable the constraint with out validating for the existing information.
As We can accomplish the same functionality when we are adding the constraint for the first time.
Ex: alter table scott.emp add constraint fk_deptno foreign key(deptno) references scott.dept(deptno) enable novalidate
The above SQL statement will enable the constraint with out validating for the existing information. So there is possibility of data will be there only in the child table but not in the parent table for existing information.
But in the future it will not allow to do so,if the constraint is in ENABLE staus.So i am just trying to disable the constraint to insert only into child table & trying to enable it with NOVALIDATE option .
But the following exception is coming .
SQL> alter table scott.emp ENABLE constraint fk_deptno enable NOVALIDATE;
alter table scott.emp ENABLE constraint fk_deptno enable NOVALIDATE
ORA-00905: missing keyword
SQL> alter table scott.emp ENABLE constraint fk_deptno NOVALIDATE;
alter table scott.emp ENABLE constraint fk_deptno NOVALIDATE
ORA-00933: SQL command not properly ended
Instead of dropping & recreating the same constraint , is there any alternate way to do this ?

I am working on Index issue and need to validate the structure of the index. Does validation lock the Index ?
Do we need downtime or we can do it in normal working hours.
alter index index_name validate structure;

I 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
[code]....
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.

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 global index and I want to convert it to local index.Is there a way to recreate local index with out dropping the global index.
I can create a local index first and then drop the global index. But is there a way to create it with out dropping the global index, just convert it.

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 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?

We have occurrences of enq : TX - index contentions in the database. Using the SQL ID, we have identified the INSERT statement and the table which they are trying to insert.
This table has almost 25 different indexes, some of which are unique as well.I am wondering how to identify the actual index causing issue, out of these 25 indexes.
Is there any way to pin point to the name of index which is causing the lock?My plan is, once the index is identified, I would like to check the extents and inittrans and other attributes of this index to fix.

In PL/SQL Plus, i can enable/disable auditing when i connect as sysdba by using these command:
SQL> ALTER SYSTEM SET audit_trail=db SCOPE=SPFILE

SQL> startup
I've done it successfully with PL/SQL Plus command line. But in PHP, how can i do that?How to execute "shutdown" and "startup" from PHP?
I've found this code for connect to oracle as sysdba:
oci_connect("/", "", null, null, OCI_SYSDBA);
From the following link:

I have Apex 4.1.1.00.23 and I want enable Session State Protection (just for testing and for learning how this works).
When I go to Home --> Application Builder --> Application 121 --> Shared Components --> Session State Protection and I click Set protection button I get to the page where I have 3 options (Disable, enable and Configure SSP).
After clicking on enable option, I get to page [URL].......
There is no Finish or submit or complete or confirm button, only cancel and previous (print screen is on picture). I found out that SSP is already enabled so I can't enable it again. But other question is still open, how to get it now to work in real.

I knew, how to enable or disable a constraint on a table.
>alter table <table_name> disable constraint <constraint_name>;
But if we know all the data is correct, it's better to disable all constraints to improve the performance.
We are allowed to Disable or Enable only a single constraint.
Enable or Disable All Constraints.

I have a job that runs the following commands for each table in a schema.. (I just inherited it ugggg)
alter table ODS.ODS_MONTHLY_MF_AUM enable row movement;
alter table ODS.ODS_MONTHLY_MF_AUM shrink space;
alter table ODS.ODS_MONTHLY_MF_AUM disable row movement;
On occassion I get this error when enabling row movement
ERROR at line 1:
ORA-00054: resource busy and acquire with NOWAIT specified
Other than dealing with apps that depend on ROWID's is there any negative impact to always keeping row movement enabled for tables.
Secondly, does any body have a script that can determine if the space really needs to be shrunk for a table.

How can I enable NOLOGGING in an External Table ?
My Table FT_PRICE_COST_MASTER is taking a long time(more than 1 hour) to excute inside the procedure. The statement is:
SELECT SUBSTR(m.sr_no,1,16) SR_NO, m.SKU_CODE, m.location_code, m.start_date, m.end_date, m.COST, m.tax, m.octroi, m.freight, m.cash_disc, m.scheme_disc, m.mrp, m.csp, m.rsp1_qty, m.rsp1_value, m.rsp2_qty, m.rsp2_value, m.rsp3_qty, m.rsp3_value, m.net_cost, m.final_cost, m.current_margin, m.pc_effect, m.created_by, m.creation_date, m.modified_by, m.modification_date, m.change_ind, m.tax_code,
[code]......
When I am recreating the External table with NOLOGGING keyword at the bottom of the synatx, it's showing "operation not supported". Else are there any other points that I should look to increase the execution time of the above statement ?

i am writing a script for inserting rows in a table where primary key of that table consists of 4 columns. I want to add a new row where 3 columns of that table will be same but change the value of the last one. this is giving an error saying that i am violating the unique constraint. I tried to disable that constraint/PK by following statement but still this error is coming
alter table sections_budgets modify primary key disable cascade;
OR
alter table sections_budgets modify constraints sec_bdgt_pk disable cascade;
the insert statement which i am using. The first four columns are part of PK
insert into sections_budgets (SELECT sb.bdgt_cd, sb.bdgt_dpf_cd, sb.bdgt_yr, :sec_code, sb.usf_usr_id,
sb.aty, sb.comaty, sb.comytd, sb.expn_ytd, sb.sys_dt, sb.cat,
sb.start_aty, sb.expn_lmt
FROM sections_budgets sb
WHERE sb.bdgt_dpf_cd = :b_d_code AND sb.bdgt_yr = :year);
is there any other way of inserting records in this table without droping the whole table because it contains too many triggers and constraints?

We are looking for validating our product upgrade changes. As part of product upgrade, there will be changes to the schema.
Like addition of tables, addition of columns to existing tables, change the length of character columns, add new index, etc. We want to verify on the database, that these SQL are run successfully on the database.
Is there a table/view, that can be queried to figure out whether such sql was run and the status of the execution, after some time (day or two) after these are actually run on the database.
