Can I reduce the execution time for a step in a TestStand ?

Hi,
I calculated the a single step execution time for TestStand Ver 2.0. It comes to around 20 milliseconds/step. Can I reduce this excution time ?
Are there any settings available for configuring execution time parameters except result logging and exception handlings to reduce the execution time ?

It's difficult to tell how you what time you are reporting for your step. Clearly we don't have control of the time it takes your code to execute. However, we are constantly working on reducing the overhead of calling the code. In addition, you don't mention the type of step you are calling. One way to have a common reference is to use the example \Examples\Benchmarks\Benchmarks.seq. Below have have posted the results of running this sequence with both tracing and result collection enabled and then disabled. I have a 700 MHz, 128 MB RAM, Dell PIII laptop. In this example there is no code within the code modules. You notice that calling a DLL has the least overhead with a minimum of 7.459 ms with tracing and results enabled and 0.092 ms with tracing and results disabled. Although not included below, if I enable results be disable tracing I get a minimum time of 0.201 ms, a 100x improvement on your time.

Reduce the execution time for the below query

Hi,
Please help me to reduce the execution time on the following query .. if any tuning is possible.
I have a table A with the columns :
ID , ORG_LINEAGE , INCLUDE_IND ( -- the org lineage is a string of ID's. If ID 5 reports to 4 and 4 to 1 .. the lineage for 5 will be stored as the string -1-4-5)
Below is the query ..
select ID
from A a
where INCLUDE_IND = '1' and
exists (
select 1
from A b
where b.ID = '5'
and b.ORG_LINEAGE like '%-'||a.ID||'-%'
order by ORG_LINEAGE;
The only constraint on the table A is the primary key on the ID column.
Following will be the execution plan :
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=406 Card=379 Bytes=2
653)
1 0 SORT (ORDER BY) (Cost=27 Card=379 Bytes=2653)
2 1 FILTER
3 2 TABLE ACCESS (FULL) OF 'A' (Cost=24 Card
=379 Bytes=2653)
4 2 TABLE ACCESS (BY INDEX ROWID) OF 'A' (Co
st=1 Card=1 Bytes=6)
5 4 INDEX (RANGE SCAN) OF 'ORG_LINEAGE'
(NON-UNIQUE)

I order it by the org_lineage to get the first person. So it is a result problem? The order by doesn't give you the first person, it gives you a sorted result set (of which there may be zero, one, or thousands).
If you only want one row from that, then you're spending a lot of time tuning the wrong query.
How do you know which ORG_LINEAGE row you want?
Maybe it would help if you posted some sample data.

How can we reduced the patch time for u6394500.drv

Hi,
This patch generally takes 14-15 hours to upgrade R12.0.4 , I want to If some body have pointers to reduce the patch applying time.
thanks in advance

You could try disabling archivelog mode while patching, and use 4 workers per CPU core that you have on the database server.
You can try using a staged appl_top approach, but that will not likely help much since 12-13 hours of that time is spent in the database portion.

TO REDUCE THE EXECUTION TIME OF REPORT

HI,
     CAN ANYONE TELL ME THAT, HOW CAN I REDUCE THE EXECUTION TIME OF THE REPORT. IS THERE ANY IDEA TO IMPROVE THE PERFORMANCE OF THE REPORT.

Hi Santosh,
Good check out the following documentation
<b>Performance tuning</b>
For all entries
Nested selects
Select using JOINS
Use the selection criteria
Use the aggregated functions
Select with view
Select with index support

<b>Optimizing the load of the database</b>
For all entries
The for all entries creates a where clause, where all the entries in the driver table are combined with OR. If the number of entries in the driver table is larger than rsdb/max_blocking_factor, several similar SQL statements are executed to limit the length of the WHERE clause.
The plus
Large amount of data
Mixing processing and reading of data
Fast internal reprocessing of data
Fast
The Minus
Difficult to program/understand
Memory could be critical (use FREE or PACKAGE size)
Some steps that might make FOR ALL ENTRIES more efficient:
Removing duplicates from the the driver table
Sorting the driver table
If possible, convert the data in the driver table to ranges so a BETWEEN statement is used instead of and OR statement:
FOR ALL ENTRIES IN i_tab
WHERE mykey >= i_tab-low and
        mykey <= i_tab-high.
Nested selects
The plus:
Small amount of data
Mixing processing and reading of data
Easy to code - and understand
The minus:
Large amount of data
when mixed processing isnt needed
Performance killer no. 1
Select using JOINS
The plus
Very large amount of data
Similar to Nested selects - when the accesses are planned by the programmer

Using table buffering
Using buffered tables improves the performance considerably. Note that in some cases a stament can not be used with a buffered table, so when using these staments the buffer will be bypassed. These staments are:
Select DISTINCT
ORDER BY / GROUP BY / HAVING clause
Any WHERE clasuse that contains a subquery or IS NULL expression
JOIN s
A SELECT... FOR UPDATE
If you wnat to explicitly bypass the bufer, use the BYPASS BUFFER addition to the SELECR clause.
Use the ABAP SORT Clause Instead of ORDER BY
The ORDER BY clause is executed on the database server while the ABAP SORT statement is executed on the application server. The datbase server will usually be the bottleneck, so sometimes it is better to move thje sort from the datsbase server to the application server.
If you are not sorting by the primary key ( E.g. using the ORDER BY PRIMARY key statement) but are sorting by another key, it could be better to use the ABAP SORT stament to sort the data in an internal table. Note however that for very large result sets it might not be a feasible solution and you would want to let the datbase server sort it.
Avoid ther SELECT DISTINCT Statement
As with the ORDER BY clause it could be better to avoid using SELECT DISTINCT, if some of the fields are not part of an index. Instead use ABAP SORT + DELETE ADJACENT DUPLICATES on an internal table, to delete duplciate rows.
Good Luck and thanks

How can I get the elapse time for execution of a Query for a session

Hi ,
How can I get the elapse time for execution of a Query for a session?
Example - I have a report based on the procedure ,when the user execute that it takes say 3 min. to return rows.
Is there any possible way to capture this session info. for this particular execution of query along with it's execution elapse time?
Thanks in advance.

Hi
You can use the dbms_utility.get_time tool (gives binary_integer type value).
1/ Initialize you time and date of beginning :
v_beginTime := dbms_utility.get_time ;
2/ Run you procedure...
3/ Get end-time with :
v_endTime := dbms_utility.get_time ;
4/ Thus, calculate elapsed time by difference :
v_elapsTime := v_endTime - v_beginTime ;
This will give you time elapsed in of 100th of seconds...
Then you can format you result to give correct print time.
Hope it will help you.

Keep in mind that Logic also has a limit of 8550 quarter notes. So changing the time signature to 4/8 can get longer recording times. So make sure you change this setting along with the song end. See page 93 in the reference manual.

Is it still running? Almost half an hour now.
By the time we find a solution maybe it's already done :)
I don't think you could do much after it's already started. As long as it's not hung, it will finish sooner or later. Make sure there are no other applications runing on the server to compete CPU and diskio with oracle.

How can I reduce the storage needs for iMovie events (raw video)

Good news - After borrowing an 8mm analog camcorder (mine died years ago) and an older digital camcorder (mine doesn't support A/V in) I have been able to set up a "bridge" to convert our old 8mm home videos to digital and import them to iMovie.
Bad news - At 13GB per 8mm tape, plus the Mini DV tapes we also have, getting it all in the computer with room to grow is going to require at least 500GB of space, which I don't have. On hand are 120GB internal (MacBook), 120GB external (Time Machine) and 40GB portable.
After my experience with the 8mm analog camcorder (it died, couldn't buy them anymore, tapes useless) I want to get everything digital in a standard format with backup.
1) Is there any way to reduce the storage space required for the raw video (Events) without impacting image quality (already mediocre in the tapes converted from analog)?
2) What's the best way to squeeze an hour of video down to fit on a DVD but still leave the video available for re-import/editing in the future? I'd likely mail the DVDs to my parents house or something to keep them separate.
Thanks!

Hi
You can also use
Yousendit (google it)
where You can send 200Mb movies
- You download Your movie to them
- get an Internet address back ( url - I think it's called )
- this You copy and send in Your e-mail to those that want's Your movie
- and now they can get it from same address
If You pay You can send up to 2Gb (if I remember right)
BUT it will take time ! In most of my cases - burn it onto a DVD and send by snail-mail most often are a better solution.

Performance Tuning -To find the execution time for Select Statement

Hi,
There is a program that takes 10 hrs to execute. I need tune its performance. The program is basically reading few tables like KNA1,ANLA,ANLU,ADRC etc and updates to Custom table. I did my analysis and found few performance techniques for ABAP coding.
Now my problem is, to get this object approved I need to submit the execution statistics to client.I checked both ST05 and SE30. I heard of a Tcode where we can execute a select statement and note its time, then modify and find its improved Performance. Can anybody suggest me on this.
Thanks,
Rajani.

Hi,
This is documentation regarding performance analysis. Hope this will be useful
It is a general practice to use           Select * from <database>     This statement populates all the values of the structure in the database.
The effect is many fold:-
     It increases the time to retrieve data from database
     There is large amount of unused data in memory
     It increases the processing time from work area or internal tables
It is always a good practice to retrieve only the required fields. Always use the syntax      Select f1 f2 fn from <database>
e.g.     Do not use the following statement:-
     Data: i_mara like mara occurs 0 with header line.
     Data: i_marc like marc occurs 0 with header line.
     Select * from mara
          Into table i_mara
          Where matnr in s_matnr.
     Select * from marc
          Into table i_marc
          For all entries in i_mara
          Where matnr eq i_mara-matnr.
     Instead use the following statement:-
                                   Data: begin of i_mara occurs 0,
                                        Matnr like mara-matnr,
                                              End of i_mara.
     Data: begin of i_marc occurs 0,
          Matnr like marc-matnr,
                                        Werks like marc-werks,
                                             End of i_marc.
     Select matnr from mara
          Into table i_mara
          Where matnr in s_matnr.

Can I edit the start time for all the podcasts from a single subscription downloaded to my itunes? i.e. want to creat a playlist of all the podcasts I have from a particular show...

I want to creat a playlist of all the podcasts I have from a particular show, want to edit out the first minute on all to skip the intro. Do not want to edit over 200 podcast manually. Is there a solution?

View menu -> Show Status Bar
Then the total play time for any group of tracks you select in the Songs area, for any selected album or for any selected playlist will show at the bottom of the iTunes window as in previous versions.
The ability to open playlists in separate windows was for some unfathomable reason removed in iTunes 11. Whether it will ever come back none of us here can say, but you can express your need for that feature via Apple's feedback page:

Is it possible to limit the execution time for a query?

I have an application that will run a query to gather statistics. The time window is defined by the user. Since the polling period for data collection varies, it is not possible to say that a large time window will result in a large resultSet. I may have a polling period of 1 minute or a polling period of 1 hour.
I want to avoid a user executing a query that will consume too many resources and inpact the system's performce in general. Could I stop a query after it takes more that x secs? Is there a way to write an sql statement indicating the max response time? similar to rownum?

You can also create an Oracle profile with limited resources and assign it to the Oracle account running the queries (this profile will be used for all queries run by the corresponding user). Resources can only specifed in cpu time (not elapsed time) or logical reads.

Reducing the fex time for N2K dual homed to N5K

Hi,
We have N2K dual homed to 2 N5K. The N2K registers the fex with one of the N5K. But when one of the N5K fails it takes more than a minute to register with the second N5K.
How can we reduce this delay so that there is minimum timeout between failover ?

Reduce the execution time of a insert

Hello,
I have a table called LINK_TABLE that contains a field called LINK_ID that identify with an ID the links of a network and other two fields called START_NODE_ID and END_NODE_ID that contains the ID of the start node and the ID of the end node for each link. This table has 7 Millions of record.
Then I have a table called NODE_TABLE that contains a field called NODE_ID that identify the all nodes of the network (i.e. all the START_NODE_ID and END_NODE_ID without duplicates ). This table has 6 Millions of record
Now, I created a new table of links called LINK_TABLE2 that derive from the LINK_TABLE with these conditions:
INSERT INTO LINK_TABLE$ USING SELECT * FROM ITALIA_LINK$ WHERE (FRC>=0 AND FRC<=6) AND FEATTYP<>4130;The table LINK_TABLE has now 3 Millions of record.
NODE_TABLE2 must have only the NODE_ID that are the START_NODE_ID and END_NODE_ID of the table LINK_TABLE2 ( without duplicates ). So, I'm doing this insert:
INSERT INTO NODE_TABLE2 USING SELECT * FROM NODE_TABLE n WHERE (n.node_id IN (SELECT start_node_id FROM LINK_TABLE2) OR n.node_id IN (SELECT end_node_id FROM LINK_TABLE2));but this second insert is working from about 15 hours.
I have 4GB RAM (oracle is using it for 30%), Quad core of CPU (oracle is using it for 100%).
Is it possible?
Is there a fast method for do this?
Thank you very much in advance.

example:
LINK_TABLE
LINK_ID: 50, 51, 52
START_NODE_ID: 10, 11, 12
END_NODE_ID: 20, 21, 22
where:
10 and 20 are the start point and the end point of the link (or street) 50;
11 and 21 are the start point and the end point of the link (or street) 51;
12 and 22 are the start point and the end point of the link (or street) 52;
NODE_TABLE
NODE_ID: 10, 11, 12, 20, 21, 22
LINK_TABLE2
LINK_ID: 50, 52
START_NODE_ID: 10, 12
END_NODE_ID: 20, 22
now, NODE_TABLE2 must have only:
NODE_TABLE2
NODE_ID: 10, 12, 20, 22.
Is it clear?
thank you very much.
