But make sure you understand the caveats you can run into!
It would be better to post the outcome of select * from v$version; first.
Also and execution plan would be nice to see.

how to improve my mac pro speed

You don't have a Mac Pro, you have a MacBook Pro. There is no way to make it faster because you cannot replace the CPU with a faster one. You can add more RAM to help improve performance when you have a lot of concurrent applications running or use memory hungry applications. You can add a faster disk drive to improve the speed of I/O. You can sell it and buy a faster model.

How to tell if a user is issuing 'alter session statements'

When I run 'alter session' from sqlplus in my schema, this does not get parsed and go to v$sql or show up in v$open_cursor. I have a user that is running queries from informatica. He says he is passing alter session statements through informatica, I want to see if they actually get there. The person is not real versed in oracle and I don't know informatica.
i cant turn on trace cause he connects and disconnects and this would run immediately, I am not in a position to turn on system level tracing, add a trigger, or turn on auditing (not allowed).
anyway to tell from a data dictionary view or something like that if these were issued by a given session? The queries run for a few minutes, so I have a bit before his session disconnects to query the data. I can't get him to change his code to stay connected. Is there a view that shows parameter changes for a given session?
oracle: 10.2.0.5
4 alter session commands are:
Alter session set sort_area_size=999999999;
Alter session set hash_area_size=999999999;
Alter session set db_file_multiblock_read_count = 128;
alter session enable parallel dml;

i cant turn on trace cause he connects and disconnects and this would run immediately, I am not in a position to turn on system level tracing, add a trigger, or turn on auditing (not allowed). If Informatica connects to Oracle via network, capturing TCP/IP traffic and mining in it may be your last resort.
you can get session's PDML status from
select pdml_status from v$session;
i cant turn on trace cause he connects and disconnects and this would run immediatelythis contradicts to your following statement
The queries run for a few minutes, so I have a bit before his session disconnects to query the data.
I can't get him to change his code to stay connected. Informatica should have debug. Ask him if he can go step by step.

How to improve SQL table perfomance

Hi,
I have one table having 5lacks recording during the select operation the query is very slow. The table is in third normal form having primary key and index.Is there any other way to improve table performance....

Generally consider indexing ON clause and WHERE clause columns.
Also make sure the WHERE clause predicates are SARGable:

How to improve SQL Query

Hi, I have to search record from one table that consists of more than 75 million row records. I've try to index in this table.
My problem is query result execute so slowly. How to increase the performance so i can get query result quickly ??
here is my explain plan :
PLAN_TABLE_OUTPUT
Plan hash value: 2042796762
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 12 | 45118 (10)| 00:09:02 |
|* 1 | TABLE ACCESS FULL| EID_DATA | 1 | 12 | 45118 (10)| 00:09:02 |
Predicate Information (identified by operation id):
1 - filter(RAWTOHEX("UID_DATA")='80297CFA353B0488')
13 rows selected
Thank you..

Hi,
if you have an index on UID_DATA, the query cannot benefit from it because the column is wrapped in RAWTOHEX function. Creating a function-based index on RAWTOHEX(UID_DATA) should help. If this function call wasn't added to the query explicitly, then you should work on why it showed up there and how to get rid of it.
Next time you post a similar problem, please don't forget to include the query's text.
Best regards,
Nikolay

How to improve sql server query response time

I have a table that contains 60 million records with the following structure
1. SEQ_ID (Bigint),
2. SRM_CLIENT_ENTITIES_SEQ_ID (Bigint),
3. CUS_ENTITY_DATA_SEQ_ID (Bigint),
4. SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID (Bigint),
5. ATTRIBUTE_DATETIME (DateTime),
6. ATTRIBUTE_DECIMAL (Decimal(18,2)),
7. ATTRIBUTE_STRING (nvarchar(255)),
8. ATTRIBUTE_BOOLEAN (Char(1)),
9. SRM_CLIENTS_SEQ_ID (Bigint)
Clustered index with key SEQ_ID
Non unique non clustered index : I've following four composite indexes
a. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_DATETIME
b. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_DECIMAL
c. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_STRING
d. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_BOOLEAN
The problem is that when i execute a simple query over this table it does not return the results in an acceptable time.
Query:
SELECT CUS_ENTITY_DATA_SEQ_ID FROM dbo.CUS_PIVOT_NON_UNIQUE_INDEXES WHERE SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID = 51986 AND ATTRIBUTE_DECIMAL = 4150196
Execution Time : 2 seconds
Thanks

Did you look at the execution plan.
The query may not use none of the indexes. The Clustered index is on SEQ_ID and the non clustered index doesn't start with SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID
OR ATTRIBUTE_DECIMAL.
The order of the columns in an index matters. Just for testing ( if it is not prod. environment) Create an NCI with SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID
and ATTRIBUTE_DECIMAL and check.

How to improve spreadsheet speed when single-threaded VBA is the bottleneck.

My brother works with massive Excel spreadsheets and needs to speed them up. Gigabytes in size and often with a million rows and many sheets within the workbook. He's already refined the sheets to take advantage of Excel's multi-thread recalculation and
seen significant improvements, but he's hit a stumbling block. He uses extensive VBA code to aid clarity, but the VB engine is single-threaded, and these relatively simple functions can be called millions of times. Some functions are trivial (e.g. conversion
functions) and just for clarity and easily unwound (at the expense of clarity), some could be unwound but that would make the spreadsheets much more complex, and others could not be unwound.
He's aware of http://www.analystcave.com/excel-vba-multithreading-tool/ and similar tools but they don't help as the granularity is insufficiently fine.
So what can he do? A search shows requests for multi-threaded VBA going back over a decade.

Hi,
>> The VB engine is single-threaded, and these relatively simple functions can be called millions of times.
The Office Object Model is
Single-Threaded Apartments, if the performance bottleneck is the Excel Object Model operation, the multiple-thread will not improve the performance significantly.
>> How to improve spreadsheet speed when single-threaded VBA is the bottleneck.
The performance optimization should be based on the business. Since I’m not familiar with your business, so I can only give you some general suggestions from the technical perspective. According to your description, the size of the spreadsheet had reached
Gigabytes and data volume is about 1 million rows. If so, I will suggest you storing the data to SQL Server and then use the analysis tools (e.g. Power Pivot).
Create a memory-efficient Data Model using Excel 2013
and the Power Pivot add-in
As
ryguy72 suggested, you can also leverage some other third party data processing tool
according to your business requirement.

How to improve speed of data acquisition? Help needed urgently.

I want to convert analog signals to digital signals and simultaneously perform some search on the data acquired and this whole process has to be done continuously for few hours.
So I tried writing two programs in Matlab, one acquires the analog data and converts it to digital and saves the data in small chunks on hard disk (like file1, file2, file3,...) continuously. The other program performs the search operation in those chunks of data continuously. I run both the programs at a time by opening two mat lab windows.
But the problem Iam facing is that the data acquisition is slow. As a result I get an error message in the second program saying that
"??? Error using ==> load
Unable to read file file4.mat: No such file or directory."
Iam unable to synchronize the two programs. I cannot use timers in search program because I cannot add any delays.
Iam using a NI PCI-6036E ,16 Bit Resolution ,200 KS/s Sampling Rate A/D board.
Should I switch to some other series such as M series having sampling rate of the order MS/s?
Can anyone please tell me how to improve the speed of data acquisition?
Thanks.

Need to spell this out a bit more..
But speed via 2.4ghz to the TC is restricted by Apple to max 130mbps link speed.. much slower actual transfer.. latest TC and laptops can do 450mbps on 5ghz but you need to be up close.. so place the TC near the device using it.. and force 5ghz connection by using a different name for 5ghz network.

How to increase internet access speed of OS X 10.5.8 whilst using telstra prepaid wirless broadband internet stick in Darwin, Australia

Is it possible to increase internet access speed of Mackbook Pro OS X 10.5.8 whilst using telstra prepaid wirless broadband internet stick in Darwin, Australia?
How can i do this?

Network Utility (in the Utilities folder) can tell you, in the Info pane, what speed you are actually connecting at.
Just set the interface to the one you are using (which may show up as en2 or something). Link Staus and speed are shown along with error counts.
If the data rate is very different from what you expected, you may have it manually set to a lower rate.
YouTube files are enormous -- that may be the best it can do.

There's also iGetter: http://www.igetter.net
You may also want to look on how to optimize your network settings to achieve an overall networking improvement (not just "download speed")
There are 2 utilities that do this for you:

Of course, if you're familiar with unix you can achieve such (and even better) optimizations by writing your own scripts

How to improve the response speed

Dear Consultants,
In BI 7.0 EP Environment, displaying 40000 detailed records wasted 3 minutes, this speed is slowly.
How to improve the response speed ?
Please give me some proposals and methods to solve this question.
Thanks a lot & Best Regards
Ricky

Hello,
3min. is not so bad for 40000 rows of data. Firstly you can analyze where the time spent is it olap or DB. you can use RSRT for analysis.
Then,
1. Create aggregates
2. Use caching and precalculation
3. check 'Use Selection of Structure Elements' from properties of query in RSRT
4. Remove unnecessary calculations from query
5. remove unnecessary rows. try to make them free characteristics.
6. If there is unused data in infocube, you can archive this data.
regards,

HOW TO IMPROVE PERFORMANCE ON SUM FUNCTION IN INLINE SQL QUERY

SELECT NVL(SUM(B1.T_AMOUNT),0) PAYMENT,B1.ACCOUNT_NUM,B1.BILL_SEQ
FROM
SELECT P.T_AMOUNT,P.ACCOUNT_NUM,P.BILL_SEQ
FROM PAYMENT_DATA_VIEW P

AND P.CLASS_ID IN (-1,1,2,94)
) B1
GROUP BY B1.ACCOUNT_NUM,B1.BILL_SEQ
Above is the query.If we run inner query it takes few second to execute but while we are summing up the same amount and bill_Seq using inline view, it takes time to execute it.
Note: Count of rows selected from inner query will be around >10 Lac
