I am looking for information on oracle performance on Niagara processors (T1000/T2000).
Does oracle benefits from the Niagara architecture(Multi threaded)? Do we see any improvements or delays in DMLs?
I am getting temp tablespace error "ORA-01652: unable to extend temp segment by 128 in tablespace TEMP" for the following code.
SELECT /*+ USE_NL ( vd1 ,vd2 ,vd3 ) leading ( vd1 ,vd2 ,vd3 , tvd) */ vd1.vendor_record_seq_no,
tvr.checksum, tvr.rownumber, tvr.transaction_type, 'U'
FROM vendor_data vd1, vendor_data vd2, vendor_data vd3,
(SELECT rownumber, MAX (DECODE (control_column_seq_no, 91150, original_value, NULL)) AS value1,
[code]...
Right now used tables has the following number of records-
SELECT COUNT(*) FROM vendor_data --292890442
SELECT COUNT(*) FROM temp_vendor_data --0
SELECT COUNT(*) FROM temp_vendor_record --0
This query is part of an application, but consuming too much of temporary tablespace (68 GB allocated). I found it out by using query below:
select * from v$session a, v$sql b
where a.sql_id=b.sql_id
and status = 'ACTIVE'
I am not sure, why this problem is occuring.
How do i find a particular SQL or a set of SQL's which are excuted against a table (user identified table) that is either a very frequently executed query against that table or high impact SQL against that table? I am currently looking through the AWR reports to go through all the queries but i was wondering if there are any dictionary views where we can find this info from?
View 2 Replies View RelatedI have a Datamart DB which has a continuously increasing volume. I run a daily optimize job, to have the data analysed using the below:-
EXECUTE dbms_stats.gather_schema_stats(ownname=> 'xxx' ,estimate_percent=> 25 , DEGREE => 4, cascade=> TRUE );
analyze table xxx.abc compute statistics; But this optimization itself is taking nearly 4 hrs to complete and I can't afford to have the delay.
Is there a better way of running this optimization?
We have a program that is taking about 13-14 hours to run and we need to generate traces to see where it is taking so long. I usually use 10046 for the tracing, I'm wondering if the traces can be built incremently so that it doesn't become one huge trace file.
View 14 Replies View RelatedThe scale of the tests that generate the following scenario is not huge right now, only 50 users simulated (or you can think of them as independently running threads if you like). But here is the crunch, the queries generated (from generic transaction layer) are all running against a table that has 600 columns! We can't really control this right now, but this is causing masses amounts of IO (5GB per request) making requests queue for disk availability (which are setup RAID 0/1); its even noticable for as few as 3 threads.
I have rendered the SQL on one occasion to execute in 13 seconds for a single user but this appears short lived as when stats were freshly gathered it went up to the normal 90-120 seconds. I've added the original query to the file, however the findings here along with our DBA (who I trust implicitly) suggest that no amount of editing the query will improve the response times, increasing the PGA/SGA (currently 4/6GB respectively) will only delay the queuing for a bit and compression can work either. In short it looks as though we've hit hardware restrictions already for this particular scenario.
As I can't really explain how my rendered query no longer takes 13 seconds, it's niggling me that we might be missing a trick.So I was hoping for some guidance on possible ways of optimising these type of queries against such wide tables, in other words possibilities that we haven't considered...
Attached is the query and plan.
I have a Query(report) which is running in <5 mins in one Scheme, where as the same is running for a long time in second schema. I have identified that an Index is scanning for more than 2000 Millions of records in second Schema, but this is scanning only 440 Millions in First Schema and hence it is fast. I am expecting the same to be done in Second schema.
I have verified the following
All records in tables in 2 schemas are same.
All indexes are same
Analyzed the tables
Gathered Histogram on all the columns as per the first schema.
But now i still have the same problem, don't know what could be the problem.

Our application servers will be running a SELECT which returns zero rows all the time.This SELECT is put into a package and this package will be called by application servers very frequently which is causing unnecessary CPU.
Original query and plan
SQL> SELECT SEGMENT_JOB_ID, SEGMENT_SET_JOB_ID, SEGMENT_ID, TARGET_VERSION
FROM AIMUSER.SEGMENT_JOBS
WHERE SEGMENT_JOB_ID NOT IN
(SELECT SEGMENT_JOB_ID
FROM AIMUSER.SEGMENT_JOBS) 2 3 4 5 ;
[code]....
Which option will be better or do we have other options?They need to pass the column's with zero rows to a ref cursor.
How can we check completion status for running sql query. i.e. how much % completed

View 2 Replies View RelatedI have installed an Express edition of Oracle 11 database on one host (Windows 7) and want to access to from another host (Backtrack Linux based on Debian) from SQL*PLUS Instant client.
While I managed to resolve multiple issues with shared libraries, I am still not able to run the sqlplus command as Oracle. I get the following errors:
oracle@evil:~/instantclient$ sqlplus
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
I followed the installation manual by Oracle and also created Oracle user with 2 env. variables set to:
LD_LIBRARY_PATH=/opt/Oracle/instantclient/lib
ORACLE_HOME=/opt/Oracle
Note that I only installed SQPLUS client on Linux and there is no DB running. The version of sqlplus is 11.2.0.3.0
On different forums people advised to set other variables according to the DB installed but I have none. All I want is to run sqlplus with the IP address, SID, port and username. Is it feasible to have only SQL*PLUS client installed .
I have Oracle 11g R2 (11.2.0.1) with Oracle EM running on Solaris 10 with ZFS.When I start OEM it comes up and tells me that the listener is running but that the DB instance is down and agents are down.I know that the instance is up because I can start it manually.
Each time I start emctl, lsnrctl and DB manually everything starts running but OEM returns a failure for the DB. long as the display shows the DB not running OEM won't allow me to work in it.Instead of getting the login page I get the Database Control Page stating that "Enterprise Manager is not able to connect to the Database instance."I have tried the various emca -config dbcontrol db -repos drop and recreate but no luck.
Is there a way to uninstall/reinstall without dropping the DB?Are there control/configuration files I may hack to tell OEM the correct information?
I am using oralce 10g database,because of performance hit in my database in want to generate AWR and STATSPACK reports.

Guest: Using Virtual PC on Win7, created a VM using XP-Mode. Installed Oracle and everything on it. I can connect to the Oracle from within the guest env using sqlplus. Listener is also running, checked with 'lsnrctl status"
Guest and Host can ping (network) each other. I installed the guest using the Microsoft Loopback Adapter. Disabled the firewall on the guest OS before the host ping could work.
So ping works both ways from guest to host and host to guest. tnsping from host fails says "no listener". When I did a "telnet 192.168.x.x 1521" from host it said could not open connection on port 1521.
