Initial execution of a workbook/query runs without ending
Hi, Experts,
I encountered a very strange behavior of Bex tool. Sometimes, Initial execution of a workbook/query runs without ending at u2018Waiting for reply from BW Serveru2019 state, then I cancel the report and run it again and it would return results within minutes. Itu2019s like it forgot to return results.
The basis team looked at the queries in the database, and said that there were actually a number of different queries being executed by my Bex query, but each individual query runs fairly quickly. The basis person pulled the statements out and ran them directly against the database and they returned result in sub seconds.
Any thoughts? Possible solution?
Thanks
ChimeiHi,
Could u let us know what is the GUI frontend patch version you are on. Also, are there any AddOn's Installed.
What version of Excel are you using. Also just for a check, run sapbexc.xla on your local machine and check the output.
Regards,

Prereq query for Logical Standby runs for days
Have had an SR open for a month that isn't getting anywhere, thought I'd check here and see if anybody has run into this.
We're looking at setting up a logical standby database, Oracle 11.2.0.3 on AIX running PeopleSoft.
There is a prereq query in the Oracle manual which is also run via the GC wizard to find tables without unique logical identifiers.
SELECT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_NOT_UNIQUE
WHERE (OWNER, TABLE_NAME) NOT IN
(SELECT DISTINCT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_UNSUPPORTED)
AND BAD_COLUMN = 'Y';
My problem is that the darned thing runs for 5.5 days.
The view in that query runs the function logstdby$tabf, which runs the following SQL over and over and over and over:
SELECT * FROM LOGSTDBY_UNSUPPORT_TAB_11_2B
Each time it runs the LOGSTDBY_UNSUPPORT_TAB_11_2B query is about 8 seconds. Run it 100,000 times and that adds up. Looks like the big problem in that query is full table scans of TAB$ and COL$.
Anybody seen it? Anybody fixed it?Good suggestion - in 15 minutes you got farther than support did in 2 weeks.
Rather than remove the sub-query, I can change it into a minus, which is functionally equivalent to the original but changes the executions on DBA_LOGSTDBY_UNSUPPORTED from many times to just once.
select owner, table_name from dba_logstdby_not_unique
where bad_column = 'Y'
minus
select distinct owner, table_name from dba_logstdby_unsupported;
The top part of the query still takes 9.5 hours to run though, with the time now being spent the following SQL which is called from the function logstdby$tabf which is called from the view DBA_LOGSTDBY_NOT_UNIQUE :
SELECT * FROM LOGSTDBY_SUPPORT_TAB_11_2B
Sorry for not putting that in the original post, but I want the original query to run if possible so the GC wizard will work - and I didn't want to clutter up the question. -
Do I still need to run the catupgrd.sql??
Hi
I would like if I install the Oracle in the following procedure, do I still need to run the catupgrd.sql.
1. Install Oracle 10.2.0.1 software only( i.e. without create any database instance)
2. Install Oracle 10.2.0.2 patch
3. Create an Oracle Instance using DBCA
Do I still need to run the catupgrd.sql for the newly created database instance?
DenisDo I still need to run the catupgrd.sql for the newly created database instance?No, you don't. Because database was created on already patched software.

Run External application without Exiting main application
Hi,
I am trying to implement a function that executes the external program from within my java application. I am using windows xp. I had googled for this and found some code but so far I am able to run the application in a condition if my main application exits. Instead I want to run the application without exiting my main application. How can I do that:
Code I am using is:
========================
try{
Runtime.getRuntime().exec("external program");
System.exit(0);
catch (Exception err){
err.printStackTrace();
System.exit(-1);
=========================
my problem is I cannot run the external program without the line "System.exit(0)". If I remove that line, the external program only starts after I exit my main java application. Is there a way to run the external application without leaving the main application?
By the way I am using the latest version of JDK 6 update 2 and Netbeans 5.5.1
ThanksI tried and I tried and I couldn't make the same problem occur unless I specfically had a long task execute BEFORE calling the runtime command. See the code below:
I tried a bunch of things, including having a GUI run before the Runtime call, after the runtime call. Neither affected the movie from being played.
I tried with different versions of the runtime command, none of it made a problem.
I tried running the application with a long task that would keep the main thread busy for a while AFTER I launched mplayer - no problem.
The only thing that made the app work the way you describe was when I built the long task that keeps the main thread active for a while BEFORE I launched mplayer (which is the state of the code as I pasted it below).
So my guess is that you have a single threaded application and you add the call to mplayer at the very end of your program's execution - thus it doesn't get called until the last thing. My suggestions:
1) Move the call to the Start of your code, not the end
2) Move your other work to a new thread so that it can be kicked off without holding the main thread in check.

}I will restate myself:
"I was not able to repeat the problem, except as described, as long as I took the hints mentioned in the article I posted into account and actually put them into action."
Of course, as soon as I ignored those hints, I was able to reproduce the error described above quite easily in all the different tests I made... But I guess the OP implemented those fixes, right? He did say he read the article...

Justr curious what the results may actually be and how to go about disabling GTK theme entirely.

Unable to run jar file without lib folder containing swing-layout-1.0.jar
I have done my project through NetBeans 5.0. Eventhough I have copied my lib foloder containing swing-layout-1.0.jar inside my project.jar, I am still unable to run my project.jar in other systems, it is creating an error as Could not find the main class. Program will exit. But if I copy the lib foloder containing swing-layout-1.0.jar in the same path as the project.jar, then my project.jar is running.
But I want to give only the project.jar for other users and not also lib foloder containing swing-layout-1.0.jar each time.
Could someone please help me with this.When you develop GUI applications using the Netbeans you may endup using netbeans specific jar files in your auto generated code.
And when you build jar files with netbeans it copy the third party jar files used in a application in to a lib folder in the same directory as the jar file of your project. And then set a class path entry to those jar files in your project jar file's manifest file.
So if you want to redistribute the package you have to redistribute your jar file and every thing in the lib folder in with the same directory structure.
If you want to change the structure you will have to change the class path to suit the new structure. -
What configuration of the new macbook pro do I need to run FCS 3 without choppy playback.
Yep, just wondering what configuration of the new macbook pro do I need to run FCS 3 without choppy playback or lagging. I'm thinking about the 7200rpm, 2.2ghz, antiglare, 4gb ram, with 1gb GPU graphics card configuration
Nothing wrong with the computer. Playback is dependent on the media and the drives.

I am installing a larger harddrive on my Mac. Can I copy the Aperture library from my backup disk running Time Machine without loosing anything? I am getting help migrating everything else on to the new harddrive, but since copying the 350Gb Aperture library takes a lot of time, I am planning to do that part myself.
I found the following information on Time Machine help about restoring Aperture library from TM
Restoring Your Aperture System
If you buy a new computer or use another system at a different location and want access to the Aperture library, you can install Aperture and then transfer the library from your vault (on your backup disk) to the other computer. If you experience equipment failure or other unexpected events, such as fire or weather-related damage to your equipment, you can easily restore the entire library to your new computer from a backup disk.

Running server app without timing out?
Hello all,
I have a server application running on a linux server and am timing out after about 15 minutes. I do not know how to make this server program run indefinately. It is an application that listens for clients and responds appropriately. Any ideas?
Thanks,
JaredHere is my code if it helps. If I should post this to a different forum would someone please tell me.
NOTE: The app is running perfectly it just stops running after a time frame.
CODE:
public class MyServerApp{
//...variable delaration etc.
try{
server = new ServerSocket(5252);//listen to the socket
//tried without this, with it set to 0, and with this number
//server.setSoTimeout(360000000);
}catch(IOException e){
System.exit(-1);
while(true){
MyConnectionThread w;//thread that handles communication
try{
w = new MyConnectionThread(server.accept());//receive new client
Thread t = new Thread(w);//create new thread with our handler
t.start();//start new thread
} catch (IOException e) {
System.exit(-1);
//...clean up
class MyConnectionThread implements Runnable{//communication handler
public void run(){//when run
//...variable declaration etc.
try{
//get streams from client socket
in = new BufferedReader(new InputStreamReader(client.getInputStream()));
out = new ObjectOutputStream(client.getOutputStream());
} catch (IOException e) {...}
while(true){
try{
line = in.readLine();//get data from client
out.writeBoolean(true);//test to see if running
out.flush();//flush information
break;//break out of loop
}catch(IOException e){break;}
try{//clean up
in.close();
out.close();
}catch(Exception e){...}
//...other functions
Hope you can help me from here. I am running it on a linux server. -
Please give an option to just open and run a download without saving.
I have a bunch of the things saved in the download folder that I have no clue what all of it is. Please I do not want to save everything I download, I would like to just open a file move on.
Thank you.sorry but there is no option like this.
but if you like you can delete them manually
for these :
1.open downloads from menu button on right or by simply pressing (Ctrl +J )
2.Then select the downloaded file you want to delete by a single click on it.
3. You will find a folder type icon on right side of that , in which you should click.
4. Then it will open folder where the selected file saved.
5. Then you can delete that file .

Query Performance - Query very slow to run
I have built a query to show payroll costings per month per employee by cost centres for the current fiscal year. The cost centres are selected with a hierarchy variable - it's quite a latrge hierarchy. The problem is the query takes ages to run - nearly ten minutes. It's built on a DSO so I cant aggregate it. Is there anything I can do to improve performance.
Hi Joel,
Walkthrough Checklist for Query Performance:
1. If exclusions exist, make sure they exist in the global filter area. Try to remove exclusions by subtracting out inclusions.
2. Use Constant Selection to ignore filters in order to move more filters to the global filter area. (Use ABAPer to test and validate that this ensures better code)
3. Within structures, make sure the filter order exists with the highest level filter first.
4. Check code for all exit variables used in a report.
5. Move Time restrictions to a global filter whenever possible.
6. Within structures, use user exit variables to calculate things like QTD, YTD. This should generate better code than using overlapping restrictions to achieve the same thing. (Use ABAPer to test and validate that this ensures better code).
7. When queries are written on multiproviders, restrict to InfoProvider in global filter whenever possible. MultiProvider (MultiCube) queries require additional database table joins to read data compared to those queries against standard InfoCubes (InfoProviders), and you should therefore hardcode the infoprovider in the global filter whenever possible to eliminate this problem.
8. Move all global calculated and restricted key figures to local as to analyze any filters that can be removed and moved to the global definition in a query. Then you can change the calculated key figure and go back to utilizing the global calculated key figure if desired
9. If Alternative UOM solution is used, turn off query cache.
10. Set read mode of query based on static or dynamic. Reading data during navigation minimizes the impact on the R/3 database and application server resources because only data that the user requires will be retrieved. For queries involving large hierarchies with many nodes, it would be wise to select Read data during navigation and when expanding the hierarchy option to avoid reading data for the hierarchy nodes that are not expanded. Reserve the Read all data mode for special queriesu2014for instance, when a majority of the users need a given query to slice and dice against all dimensions, or when the data is needed for data mining. This mode places heavy demand on database and memory resources and might impact other SAP BW processes and tasks.
11. Turn off formatting and results rows to minimize Frontend time whenever possible.
12. Check for nested hierarchies. Always a bad idea.
13. If "Display as hierarchy" is being used, look for other options to remove it to increase performance.
14. Use Constant Selection instead of SUMCT and SUMGT within formulas.
15. Do review of order of restrictions in formulas. Do as many restrictions as you can before calculations. Try to avoid calculations before restrictions.
16. Check Sequential vs Parallel read on Multiproviders.
17. Turn off warning messages on queries.
18. Check to see if performance improves by removing text display (Use ABAPer to test and validate that this ensures better code).
19. Check to see where currency conversions are happening if they are used.
20. Check aggregation and exception aggregation on calculated key figures. Before aggregation is generally slower and should not be used unless explicitly needed.
21. Avoid Cell Editor use if at all possible.
22. Make sure queries are regenerated in production using RSRT after changes to statistics, consistency changes, or aggregates.
23. Within the free characteristics, filter on the least granular objects first and make sure those come first in the order.
24. Leverage characteristics or navigational attributes rather than hierarchies. Using a hierarchy requires reading temporary hierarchy tables and creates additional overhead compared to characteristics and navigational attributes. Therefore, characteristics or navigational attributes result in significantly better query performance than hierarchies, especially as the size of the hierarchy (e.g., the number of nodes and levels) and the complexity of the selection criteria increase.
25. If hierarchies are used, minimize the number of nodes to include in the query results. Including all nodes in the query results (even the ones that are not needed or blank) slows down the query processing. The u201Cnot assignedu201D nodes in the hierarchy should be filtered out, and you should use a variable to reduce the number of hierarchy nodes selected.
