What is the need of Temp table in Oracle ? what is the advantage of Temp table over normal table ? Is temp table a log operation one. What is the scenario of using temp table in real time ?
View 4 Replieswe have a requirement for migrating data real time from source db to target db as well as to a queue.
achieve this using any custom technique?
we tried exploring Streams with CDC but Streams being depricated and CDC removed in Oracle 12 c, we are kind of stuck.

I have a primary database orcl and logical standby database orcl_std.
Real time apply is enabled. I have standby redologs in both primary and standby sides and I`ve started recovery with below command:
ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
When I create a new table in primary database, I am unable to see it on standby database (Although real time apply is enabled) However, when I switch log in primary, I can see the new table in standby database.
My question is, why realtime apply is not working in my scenerio ? I was expecting to see the new table immediately in standby database once it is created in primary database. Why am I supposed to wait for log switch in real time apply ?
When we use this kind of code in PL/SQL block.
CREATE OR REPLACE TYPE sample_object IS OBJECT
(id NUMBER
,name VARCHAR2(30));
/
CREATE OR REPLACE TYPE sample_table IS TABLE OF sample_object;
I have read some docs ,but I didn't get any information where exactly we use this.provide one real time scenario with an example.How this is different from record.
We have oracle 9i database named A with 2 schema A1 and A2.User enters data at A1 schema and the incremental data moved to A2 schema after some verfications performed by some scheduled job on A1 schema.
we want to move this incremental data to B1 schema of another oracle 9i database B at the real time when data gets entered to A2 schema of A oracle 9i database. We have access to A2 schema of A database and B1 schema of B database.way to do it or best practice to do this activity or if there is any third party tool or any available oracle utility to perform it?
Note: A2 schema of A database and B1 schema of B database has one to one mapping.We want to avoid using trigger on A2 schema, how data gets populated from A1 to A2 schema .
Can we change the condition of an item from always to none on the real time ? How ?
View 3 Replies View RelatedWith 11gr2, by default, on STARTUP, the standby database is open
-> in READ ONLY mode
-> with Intended State: APPLY-ON
so the ACTIVE DATAGUARD option is in use ....
is there a way to deactivate REAL TIME QUERY permanently, so whether on STARTUP or STARTUP MOUNT, the standby stay only mounted with Intended State: APPLY-ON
The only way i found is to do the following :
SQL> startup
DGMGRL> edit database 'PHNXENT' set state='APPLY-OFF';
then
SQL> startup mount
DGMGRL> edit database 'PHNXENT' set state='APPLY-ON';
I've got a query running a select count (*) over a table. The default plan takes in the order of 15 minutes to return, a hinted plan to use a different index takes 3 minutes to return.
Unfortunately I cant get at the index stats and a few other areas which I suspect may be key here.When running autotrace against the two queries I see fairly different values as one would expect.
Query
select count (*) from fulfilmentitem bfi where created >= sysdate-30 AND bfi.status = 'FA' AND bfi.fulfilmentmethod = 'D'

[code]....
IDX_FULFIL_METHODSTATUS is across FULFILMENTMETHOD & STATUS in that order.
IDX_BFI_CREATED is on CREATED and is approx 70% of the size of the other index
The row counts estimated in the explain plan are out, the count(*) comes in at 32.8k rows.As you will have seen, the fast run shows a pretty significant consistent get increase compared to the slow run and a decent though not dramatic physical read drop.
My uncertainty is around if these changes in consistent get/phys read values would typically be enough to suggest the real time improvements I'm observing or if other (albeit perhaps temporary) factors are involved. It is a prod OLTP environment so the data will be rapidly changing and that may be a factor.
I know it can never be an exact science without intimately knowing the hardware/current loads etc but I also know that there's enough experience on these boards to have a loose handle on if the time shifts between queries are likely (or not) to be reflective of the stat changes or if those differences alone shouldn't (or typically wouldn't account) for it.
I'm thinking about instructing the query to ignore its original plan but am hesitant to do so without being a little more confident that it's not just a timing thing or something other than the change of index approach which may be causing the improvement. the autotrace stat changes observed I couldn't put my hand on heart say "yup - that change is good, ignore the default index all the time for this job".
One of our customer have problem with following sql statement:
SELECT c.table_name, c.column_name
FROM user_tab_columns c, user_tables t
WHERE c.table_name = t.table_name
AND c.data_type IN ('CLOB', 'BLOB');
During execution it takes all the TEMP tablespace size(8GB).
I gather system stats (dbms_stats.gather_dictionary_stats(estimate_percent=>null)) but it doesn't resolve problem.Above sql statement works fine with RULE hint but I want to know what is the reason of problem with temporary tablespace.
I am trying to run on Oracle report via Oracle Application Concurrent job. Concurrent job is completing normal but I don't get anything on print out page.

I almost doubled the TEMP tablespace in size but still I am not able to get rid of this error message.

Since we are porting from SQL/Sybase to Oracle we don't want to Create too many global temporary table.

I'm having some trouble dealing with the PL/SQL coding. At the moment, I have a file (set of data) that is read using java. An array is created (line by line) and is passed into a temp. table, which is then called by the plsql (call PKG_xxx.PRC_xxx...) script/command for processing. Is there any way I could directly get the file loaded into plsql (into a temp. table maybe?)
The data are just numbers and letters. I already got the PL/SQL part to select the set I want for different cases. All I need is to get the file (directly or indirectly) for the procedure without going through java.
I need to create a temp table within a stored procedure. I want to apply some logic on the table, and then delete it when it is completed in runtime -- all inside the stored procedure.

We are using a GTT table to store the summarize data and display it on same screen(10g 10.2.0.5). Now we are facing temporary tablespace space issue very frequently as our client do not enable the auto extend on for temp table space. We have analyzed the AWR and came to know that there are 900000 inserts per hour on an average. Client DBA Claims that there are sessions(1or 2) which inserts the data in temporary table continuously for 2-3 days.
According to him one session is running from 28th Aug and problem comes on 2nd Sep and after killing the problematic session the application will work fine. Generally this problems come on weekend. I have discussed with our dev team and as per them there is no session leakage issue.
following is the insert statement:
INSERT INTO DT_CA_STNDALN_DETAILS_TMP (ORG_ID,BA_PRODTYPE_ID,MAX
TENOR,GROSSLIMIT,GROSS_UTILISATION,HAS_MDR,HAS_CLUSTER,SIGN_IN
D,GROSS_AVAILABILITY,COLLATERAL,NET_UTILISATION,DT_CA_STNDALN_DE

We had an issue with a PL/SQL package taking hours to run as a concurrent program. Database version is 10.2.0.4.0, running on Linux x86 64-bit. A tkprof'd trace file revealed the problem SQL statement to be a cursor. This one SQL statement would run for 3+ hours. I copied the SQL statement and ran it in TOAD and it completed in seconds, returning the exact same result set. To resolve the issue in the PL/SQL package I created a global temp table and ran the exact same SQL statement as an INSERT into the global temp table.
Again, instead of hours, the SQL statement completes in seconds. If I revert the change, it goes back to taking hours. I've attached the relevant sections of the tkprof showing the two SQL statements (identical other than the insert in front of one) and the resulting explain plans and performance data. I've always been under the impression that a cursor was a better option than a temp table and I've never run into a situation where the same SQL statement runs so much longer when executed as a cursor.
