Parallel execution of multiple scripts

Hi All,
I understand that by using parallel hint we can achieve parallel execution of the queries(insert/update/delete).
For my today's question I would like know if Parallelism can be achieved for the following scenario.
I have a script with an insert-select statement and multiple merge statements and few update statements all on the same table.
I have to run this script 12 times on the same table, once for each month of the year.
Currently we run for Jan (where record_date = '201001') commit it, and then run for Feb, and so on.
Can all the 12 month be run in parallel. One way I can think of is create 12 different scripts and kick them of by opening 12 different SQL Plus sessions (all on the same table).
Is there a better way of doing this ?
Note: each month data will not effect the other other month data.
Regards,
Aj

Creating 12 different scripts would be a sub-optimal solution, and a maintenance nightmare. Creating 1 parametrized script and call that 12 times with different parameters would be slightly better.
Creating 1 stored procedure with parameters, and run that procedure in the scheduler 12 times would still be better, as everything runs at the server side only.
Your description is deliberately vague, so the possibility of deadlock can not be excluded.

Parallel execution of multiple test cases.

Does flex unit 4.x version supports for parallel execution of multiple test cases?
Any help will be greatly appreciated.

No.
Flash Player and AIR are single-threaded virtual machines. The only parallel execution one could do is during asynchronous tests, but we do not support that presently for a variety of reasons.

Parallel execution of Mat script in Labview

Hi All
I have an application where I am using MatLAB program to simulate 3D image simulation for vibration data. In this we are using two Mat Script call in two instances which are running parallel.
The issue observed is MatLAB scripts which am running parallel are not working simultaneously any one is working at any time. When I call MatLAB script for second time, Mat script which is already executing stops execution and second instance gets executes.
What I have to do to execute 2 MatLAB scripts simultaneously in LABView.

I'm not a Matlab experts, but as far as I know, Matlab doesn't allow you to run scripts in parallel, so this is a Matlab limitation, not a LabVIEW one. You could look into using the Parallel Computing Toolbox for Matlab, though I think its intention is to target multiple cores, rather than multiple threads.
You may need to pursue this in the Matlab forums.

How to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller

we are using VS 2013, I need to run multiple Coded UI Ordered Tests in parallel on different agents.
My requirement :
Example: I have 40 Coded UI Test scripts in single solution/project. i want to run in different OS environments(example 5 OS ). I have created 5 Ordered tests with the same 40 test cases.
I have one Controller machine and 5 test agent machines. Now I want my tests to be distributed in a way that every agent gets 1 Ordered test to execute.
Machine_C = Controller (Controls Machine_1,2,3,4,5)
Machine_1 = Test Agent 1 (Should execute Ordered Test 1 (ex: OS - WIN 7) )
Machine_2 = Test Agent 2 (Should execute Ordered Test 2 (ex:
OS - WIN 8) )
Machine_3 = Test Agent 3 (Should execute Ordered Test 3
(ex: OS - WIN 2008 server) )
Machine_4 = Test Agent 4 (Should execute Ordered Test 4 (ex:
OS - WIN 2012 server) )
Machine_5 = Test Agent 5 (Should execute Ordered Test 5 (ex:
OS - WIN 2003 server) )
I have changed the “MinimumTestsPerAgent” app setting value
as '1' in controller’s configuration file (QTController.exe.config).
When I run the Ordered tests from the test explorer all Test agent running with each Ordered test and showing the status as running. but with in the 5 Test Agents only 2 Agents executing the test cases remaining all 3 agents not executing the test cases but
status showing as 'running' still for long time (exp: More then 3 hr) after that all so its not responding.
I need to know how I can configure my controller or how I can tell it to execute these tests in parallel on different test agents. This will help me reducing the script execution time.
I am not sure what steps I am missing.
It will be of great help if someone can guide me how this can be achieved.
-- > One more thing Can I Run one Coded UI Ordered Test on One Specific Test Agent?
ex: Need to run ordered Test 1 in Win 7 OS (Test Agent 1) only.
Thanks in Advance.

Hi Divakar,
Thank you for posting in MSDN forum.
As far as I know, we cannot specify coded UI ordered test run on specific test agent. And it is mainly that test controller determine which coded UI ordered test assign to which test agent.
Generally, I know that if we want to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller.
We will need to change the MinimumTestsPerAgent property to 1 in the test controller configuration file (QTControllerConfig.exe.config) as you said.
And then we will need to change the bucketSize number of tests/number of machines in the test settings.
For more information about how to set this bucketSize value, please refer the following blog.
http://blogs.msdn.com/b/aseemb/archive/2010/08/11/how-to-run-automated-tests-on-different-machines-in-parallel.aspx
You can refer this Jack's suggestion to run your coded UI ordered test in lab Environment or load test.

Parallel Execution against Normal Execution

Hi,
Can someone explain why in this case Serial Execution is faster although enabling parallel dml at session level , What are the possibilities to improve speed of executoin for parallel execution as i need to populate for 139 stores data having around half a million rows for each store , i will have to run a cursor on the distinct value of store to achieve this , just to test i got the following Results , can anyoe guide where i am going Wrong?
This is the Script

Parallel processing in Oracle is intended to reduce I/O latency. When you tell the kernel to do an I/O, you need to wait for that call to complete - disk platters to spin, disk controller heads to move, etc.
If you need to make a bunch of I/O calls after one another, you will spend up to 90% of the elapsed time waiting for that I/O to actually put the data into your buffer to process.
Now imagine doing a million I/Os.. and 90% of the time spend waiting for I/O to complete. A big performance knock and a frustrating one - as you cannot make that actual I/O any faster. It is simply slow. The slowest operation you can do on the computer and you're doing a million of them.
Parallel processing in Oracle addresses this problem. There can be sufficient I/O bandwidth to make a 100 I/O calls per second. But your process that does an I/O call, wait, process, and does an I/O call, wait, process, can only reach a speed of 10 I/O calls per second.
Which means 90% of the I/O pipe is free to do I/O in parallel. So instead of a single process doing that million I/Os (using 10% I/O bandwidth/thruput), Oracle spawns 10 process each doing a 100K I/Os each - thus making better use of the I/O thruput.
So Oracle PQ is useless if you scan small volumes of data - it is intended for large volumes of data. There are overheads in PQ as the parallel processes have to be coordinated in order to work together. When each only needs to do 10 I/Os, the time spend on coordination alone can be more than what the time would have been to simply do a 100 I/Os using a single process.
It is also a fallacy that number of CPUs determine the just how many parallel processes you can start. The real determining factor is the load you can put on your I/O subsystem.
Bottom line is that PQ is nothing "special" or "magic". It is simply a method to reduce I/O latency by performing parallel I/O. And it is only sensible to use when the amount of I/O to be done warrants parallel processing.
Oh yeah - and the CBO is very capable in deciding when to use PQ and not. So rather than force PQ down the CBO's throat using the PARALLEL clause and hardcoding the degrees and instances, it should rather make those decisions (as informed decisions) itself. Which means using the PARALLEL clause on tables and not as SQL hints. The DBA can easily tune that by altering the PARALLEL clause if a table.. The DBA cannot by any means do the same thing when dealing with SQLs that insists on a specific number of PQ processes on a specific number of instances.

ORA-12842: Cursor invalidated during parallel execution

Hi,
Database version: 9.2.0.6.0
OS : Red Hat AS 3.
I encountered this problem lately in one of our scripts.
The error message shows:
BEGIN SP_RPT77B_V2(SYSDATE -1); END;
ERROR at line 1:
ORA-12842: Cursor invalidated during parallel execution
ORA-06512: at "REPORTADMIN.SP_RPT77B_V2", line 273
ORA-06512: at line 1

Does anyone have any clues on what does this error messages means? Is there a way to rectified the problem?
Any advise, thanks.

Hi!
Check the error description --
ORA-12842 schema modified during parallel execution
Cause: Schema modified during the parse phase of parallel processing.
Action: No action required.
And the other error is --

Disable parallel slaves from multiple instances in RAC.

Hi All,
By default while using parallel execution in RAC slaves are spead accross multiple instances.
Why can I ensure slaves are allocated to only on that node where query is executed.
Basically to avoid interconnect trafic.
Thanks,
Raja.

It would cripple RAC, wouldn't it. It would make any query on any gv$ view impossible.
Even if it was possible, it would make your database unsupported.
Apart from that, it doesn't make sense too. You want to distribute resources, and to run on the server which is least loaded.

My questions are:
1) The execution plan shows the query using parallel hint has much less cpu cost and time compared with the one with index hint. So it seems it is better to use the parallel execution. is there any downside to use parallel hint that I should consider?
2) I can also modify the application to submit multiple queries (using index hint) in parallel (which opens multiple sessions). Is the parallel hint in the query superior to parallel queries in application?

--------------------------------------------------------------------------------------------------------------------------------- As you have forced oracle to use IDX_LOC. it is going for a [url http://docs.oracle.com/cd/B19306_01/server.102/b14211/optimops.htm#PFGRF10105]INDEX SKIP SCAN. And if the cardinality of the subindex column is low then oracle may be doing more work here. I think that is what exactly happening in your case. A simple full table scan could be more efficient.

----------------------------------------------------------------------------------------------------------------------------------------------- Again PARALLEL query has its own down side. There is no free lunch. You need to spend more resource. And most of the time in a OLTP system with multi user access its not worthwhile.
So the first thing i would suggest you is to remove all your hint and get an execution plan and post it. And read the above link provided an post all the necessary details.
You need to be first clear about your problem.

Multiple scripts running at the same time?

Is there a way to have multiple scripts successfully running at the same time?
At the moment if I start a second script while the first one is still running, the second one completes successfully but the first one stops. This seems to be because the first one is no longer the active document once the second one opens so can't continue.
Is there another way to script things like this so that multiple can run independently at the same time? You might ask why I'd want to run two at the same time and not just wait, but i've setup an asp.net web form front end and having problems if two people click the button around the same time.
I'm guessing this isn't going to be possible and i'm going to have to look for ways of doing this in asp.net instead and somehow queue the requests so you have to wait longer if the script is already running?
Thanks,
Andy

This is correct. The scripting interface to PS is single-threaded so you will need to queue up requests.

11g Parallel Execution on AIX 6 - SMT Enabled or Disabled?

Greetings,
I've had no luck searching for an answer to this question and I'm hoping someone can answer it:
Can Oracle 11g Parallel Execution spread the "granules" of paralllism across the threads (logical cpus) in an AIX SMT enabled environment, or should SMT be disabled and the "granules" be spread scross the processors (virtual cpus)? The application is a data warehouse in a non-RAC configuration using a p570 server. From what I've read, the server must be SMP for Oracle parallel execution capabilities to be maximized, but I think all AIX servers are SMP (not sure if the server needs to be ordered as an SMP server). I'm mostly concerned with the data load processing at this point, and not so concerned for the query right now. I believe AIX 6.1 can enable/disable SMT dynamically. So would it make sense to disable during data loads, and enable for DSS query?
Hope the question makes sense. Thanks for any help in advance!

SMT will determine Oracle's cpu_count parameter.
However this is a static parameter.
So it won't work, and it might be even dangerous to change it on the fly.

Make a matte in Photoshop.
From the Photoshop menu bar: File > New > Film & Video Presets. Choose one that suits your FCP project pixel dimensions. Make the background black. Place a white rectangle with rounded corners on top (the white will determine how much of your picture is visible). Flatten Image. Save as TIFF. Import into FCP.
Move your video clips up to V2. Place the imported TIFF on V1. Highlight all clips on V2.
Go to Modify > Composite Mode > Travel Matte Luma. Done.
If you want soft edges, no need for a matte. Double click your clip to place it in the Viewer. Open up the Motion tab > Crop > Edge Feather. Nice and quick. Copy and Paste attributes for the other clips.

How to run multiple scripts in sql*plus?

I would like to run 2 scripts in sql*plus, how do I do this? I tried the following, but it won't run.
create table student_new
AS
select *
from student
insert into student_new
(last_name, first_name
values
(Crop, Jenny)
The above are the two scripts I want to run, what am I doing wrong.
Thanks

Do you have a solution to run multiple scripts continuosly, one after the other as one script.
Say I have file1.sql file2.sql, file3.sql.
I want to create a script run.sql, where this will run file1.sql,file2.sql,file3.sql one after other without any one running one after the other like follows:
run.sql should have
begin
@file1.sql
@file2.sql
@file3.sql
dbms_output.put_line(select sysdate from dual);
end;
If I run run.sql all the three scripts should be executed successfully and then display the current time . All these files have update statements(50,000 updates each file).
Very urgetn. Can some one hlpe, please.
Thanks in advance.

Parallel Execution questions

Hi everyone, i have few questions about Parallel Execution.
1- Query Coordinator to scan the table, split up the table to the processes. But, each process take different number of rows. For example, in oracle 10g database architecture, thomas kyte gave an example:
"SELECT COUNT(*) FROM BIG_TABLE"
It is distributed to 4 processes. One process take 1000 rows, another process 1200 etc. Why this is not equal? How the number of rows is determined by the QC?
2- If we do not determine the degree of parallelism ( /*+ PARALLEL(B) */ instead of /*+ PARALLEL(B,16) */ ) how the cbo determine the degree of parallelism?
3- in the explain plan i see lots of thing i do not know. For example :
:TQ10000
what is that?
-> TQ, IN-OUT, PQ_Disturb columns?
thanks for responses.

Hi
Why this is not equal? How the number of rows is determined by the QC?The number of rows is not used to split the table. Data is split in granules and distributed to the slave processed based on two methods:
- partition granules: a whole partition is given to a specific slave process
- block range granules: range of blocks are given to each slave process
So, depending on the size of the granules, one slave process might process much more data than another.
If we do not determine the degree of parallelism how the cbo determine
the degree of parallelism?It depends on the configuration. In fact, there is a default at session level, at system level and at table level. Depending which ones are set, a DOP is chosen. In addition, the DOP might be decreased at runtime (before the execution starts, not dynamically during it).
For example : :TQ10000 what is that?Producers send data to consumers through so called "table queues" (TQ). The number, in your case 10000, is just a identifier generated by the database engine.
TQTable queue, e.g.: TQ10000 -> Q1,00
IN-OUTThis is the relationship between parallel operations. E.g. P->P means that a parallel operation sends data to another parallel operation.
PQ_Disturb columns?This is the method used to distribute rows. E.g. RANGE means that the producers send specific ranges of rows to different consumers.

Tracking the order of execution of sql scripts in SQL*Plus

In our production environment we sometimes have to run some .sql scripts in a particular order. Since the order of execution is important , i have created another .sql file caller caller.sql(shown at the bottom) which will call all the scripts in the right order.
i thought of putting a exec DBMS_LOCK.SLEEP (5); after the end of every execution of the script so that i can see the
'Ending script1'message .
The spooling within the caller script(execute_stack.log) has become meaningless because each script has a spool <filename.log> and spool off within it. These spool logs (for every script) is important for tracking purposes as each script belongs to a different development team and i have to send them the spooled log file after the execution.
I don't want to see the entire scripts running by in my screen. Since these scripts have their own spooling, i can later check the logs if the scripts where executed properly.
So i need two things.
1.I just need to see the following and nothing else in the screen.
Ending script1
Ending script2
Ending script3
.2. I need to log the order of execution. ie. the execute_stack.log should look like the above.Since there is a spool off within each script, this wouldn't be possible.Right?
Ending script1
Ending script2
Ending script3
.The caller.sql script which calls all the scripts in the right order
alter session set nls_date_format = 'DD-MON-YYYY hh24:MI:SS';
set serveroutput on
set echo on;
set feedback on;
spool execute_stack.log
@script1.sql
exec dbms_output.put_line ('Ending script1');
dbms_output.put_line(chr(10)||chr(10)||'.'||chr(10)||'.'||chr(10));
exec DBMS_LOCK.SLEEP (5);
@script2.sql
exec dbms_output.put_line ('Ending script2');
dbms_output.put_line(chr(10)||chr(10)||'.'||chr(10)||'.'||chr(10));
exec DBMS_LOCK.SLEEP (5);
@script3.sql
exec dbms_output.put_line ('Ending script3');
dbms_output.put_line(chr(10)||chr(10)||'.'||chr(10)||'.'||chr(10));
exec DBMS_LOCK.SLEEP (5);
@script4.sql
dbms_output.put_line(chr(10)||chr(10)||'.'||chr(10)||'.'||chr(10));
exec dbms_output.put_line ('Ending script3');

spool off;Is this a professional way of tracking the execution of .sql scripts?

Pete_Sg1 wrote:
Is this a professional way of tracking the execution of .sql scripts?No. There is very little professional about using .sql scripts on a production system - when stored procedures are safer, more robust, easier managed and controlled and secure.. and where a log table can be used to properly log the runtimes (and other stats) of each processing step.
Let's just take a look at the number of moving parts you need to schedule and run a .sql script. A cron job needs to be configured with the proper environment setting. It needs to run a shell script. That shell script needs to load SQL*Plus. SQL*Plus needs to connect to the database (starting a dedicated server process most likely). SQL*Plus then needs to read a .sql file, parse these commands and either execute these locally (SQL*Plus commands) or remotely (PL/SQL and SQL commands).
How can this be considered professional when the very same can be achieved with a
- stored procedure
- using DBMS_JOB to schedule the procedure for execution
There are so many things that can go wrong with the first method. And so few things that could go wrong with the last one. No contest as to which method is not only better, but also professional.
PS. See that you use Windows to run these scripts. It is even worse as it introduces another hardware and software layer making the scenario even more insecure & unsafe with more moving parts that can go wrong or simply fail.

CJS-00030 Assertion failed: Execution of SQL script reports an unexpected error.System Copy

Experts,
I am performing Homogeneous System copy using backup/restore method.I have taken QA system backup ie dump files and trying to build on Sandbox system for testing purpose.Everything went fine and was able to load the dump but stuck at one of the point and throwing me error
ERROR [cinstallercallbackimpl.cpp:228]
CJS-00030 Assertion failed: Execution of SQL script reports an unexpected error.
When I checked the sapinst_dev log I found the below error but not able to fix it and not aware to proceed further
1> use SID
1> EXEC sp_changedbowner sapsa
Msg 17362, Level 16, State 1:
Server 'SID', Procedure 'sp_changedbowner', Line 181:
The proposed new db owner already is a user in the database or owns the database.
(return status = 1)
I am sure these may be small changes that have to be made by changing the db owner and Im not exactly sure how to perform it.
Note:I am Using the Windows environment with Sybase ase database and SWPM tool to perform.
Appreciate your suggestions
Thanks

I fixed the issue ..by changing the owner sapsa.Bingo !!!!
