No replies for thread

Hi All,
I have posted some questions in Webdynpro ABAP forum.
I did not get any replies for some of them. All of them are good ones. I always search before posting.
I closed the threads and posted them again with new subject line.
Still I could find no replies. How can I get clarified. Even moderators are not replying them.
I'm still in search of the answers. I would appreciate if the moderators share their views for those threads based on the quality of the threads. In order to get the replies where else can we post the same thread in addition to the specific forum.
Regards,
Lekha.

I hope Siegfried's quote implies only for the thread without replies.But still it is out of their interest & time to give solutions to the unanswered thread.

Before becoming a Moderator they get some time to help others with their knowledge apart from their regular work schedule but after becoming the moderator an extra burden of maintaining the forum is added up and that minimizes the percentage of sharing their knowledge.But still i dont believe that they avoid sharing their knowledge.

Yeah this kind of situations happens rarely and it happens if there is a vacation for the regular contributors of SDN so it takes some time to get the answer.

Yeah i strongly second this statement.And these men dont contribute to SDN expecting something they do it as they enjoy doing it.This can be clearly seen from their replies and contributions apart from the regular technical forums(ie.Coffee Corner)
PS: I added some missing names to the list of great men.

How can I see how many replies a thread has?

The old layout let you see how many replies a thread had. Is there any way to get that back?

Media Recovery Waiting for thread 1 sequence (in transit)

I have rebuilt our standby database using an rman duplicate since it was missing many archive logs.
Following the duplicate, the standby is now almost in sync with the primary. Logs are shipping across but are not being applied in a timely manner. How long should it take for an archive log from the primary to be applied to the standby?
I need to know this so that a proper script can be set up to check the primary and standby. At the moment they are never exactly in sync - always one sequence number behind the primary.
Why is the standby is not applying in a timely manner?
From the alert log:

The log seems to be "in transit" for a long time

I should add that I understand that for the Primary and Standby to be out by one log is not cause for concern (they are applying). Its just that I wanted to script a check that would compare them both, and and the moment they are never equal - when I understand that they should be and that the logs should be applied almost immediately.

How long should it take for an archive log from the primary to be applied to the standby?depends on network speed also.
make sure the archives are shipped to standby location.

Hi check is MRP started or not?
primary database you need not check current sequence, check last generated sequence..not current sequence.
current sequence is redo log which has been not yet archived
I think everything is perfect here.. no issues.
Hope you understood, let me know if not clear , thanks.

Visual C++ Runtime Error R6016 not enough space for thread data

3. I suspect that the problem announced by this error might also be contributing to the the fact that my Chrome browser now appears to be overlaid with a pink matt variation on its entire colour scheme. I have reported the pink matt error directly to Google

Pattern for Thread Pool?

Hi
i want to build a kind of download manager. The application should be able to handle some concurrent threads, each representing a download in progress.
I thought i might be more efficient to reuse a download thread after the download has ended as to create a new thread each time (like the connection object for db queries). Is this right? If yes, i thought to build a thread pool that serves a limited number of threaded download objects as requested (am I on the right way?).
Now, I have to basic problems: (a) is it right, that, if the run() method of a thread has ended, the whole thread gets destroved? if yes, how should i prevent the thread from being destroyed, so i can reuse it later on? Second (b) how would that pool mechnism look like, means, there must be some kind of vector where i put in and take out the threads.
As you see, these are basic "pool" technique questions. So, I thought, maybe there is a design pattern that would give me the basic mechanism, Does anyone know such a pattern?
Thanks for your help
josh

I thought i might be more efficient to reuse a
download thread after the download has ended as to
create a new thread each time (like the connection
object for db queries). Is this right? If yes, iIt may be right, if creating new threads is wasting enough CPU cycles to justify the complication of a thread pool. Maybe for a high-load server it would be more efficient. You'll have to figure that out for your own specific application.
Another good use for thread pools is to avoid putting time-consuming operations in ActionListeners, etc. Instead you can have them pass the task off to a thread pool, keeping the GUI responsive.
Now, I have to basic problems: (a) is it right, that,
if the run() method of a thread has ended, the whole
thread gets destroved? if yes, how should i prevent
the thread from being destroyed, so i can reuse it
later on? Second (b) how would that pool mechnism look
like, means, there must be some kind of vector where i
put in and take out the threads. (a) You are right. Therefore, the worker threads should not exit their run() methods until interrupted. (b) Worker threads could check a job queue (containing Runnables, perhaps) and if there are none, they should wait() on some object. When another thread adds a new job to the queue, it should call notify() on the same object, thus waking up one of the worker threads to perform the task.
I wrote a thread pool once, just as an exercise. You will run into a number of problems and design issues (such as, what should the worker threads do when interrupted, exit immediately or clear the job queue and then exit?) If you have any more questions, ask in this thead.

ORA-00280: change 84116020212 for thread 2 is in sequence #251560

Y'ello All,
While trying to recover an offline datafile on a two node RAC, it keeps asking for threads from both nodes with is normal.
My questions are:
a) Is there a script that will tell me the list of archive logs needed to recover that particular datafile?
b) I only know how to restore archive logs for one thread, see below
run
allocate channel p1 type 'sbt_tape' parms 'ENV=(tdpo_optfile=/opt/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
restore archivelog from sequence 147422 until sequence 147427 thread 1;
release channel p1;
But want to restore both threads at the same time, not running twice the rman command for thread 1 and then thread 2.
will the below work?
run
allocate channel p1 type 'sbt_tape' parms 'ENV=(tdpo_optfile=/opt/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
restore archivelog from sequence 147422 until sequence 147427 thread 1;
restore archivelog from sequence 251561 to 251573 thread 2;
release channel p1;
Kindly help and advice.
DID

Use RMAN list backup; and list backupset n; to show the datafiles and archivelogs that make up a backup or backup set. You can expand this by using list backup by file;
I guess for your thread two line, you meant
restore archivelog from sequence 251561 until sequence 251573 thread 2;The command should work

ORA-16145: archival for thread# 1 sequence# 1424 in progress

Dear All,
I am configuring data guard between primary and DR databases. After giving "recover standby database" command it is display following error.
SQL> recover standby database;
ORA-00279: change 93766011 generated at 02/22/2013 00:30:05 needed for thread 1

This is the already applied log file sequence:
SQL> select max(sequence#) from v$archived_log where applied='YES';
MAX(SEQUENCE#)
1423
I have checked archive log path and found frequently copying archive logs from sequence# 1424 and later to the physical path.
I think this is the reason for "ORA-16145: archival for thread# 1 sequence# 1424 in progress" error.
Please anyone advice why this continuous copying same archive logs from primary to DR.
Thank you in advance.

and found frequently copying archive logs from sequence# 1424 and later to the physical pathDo you mean that Oracle is automatically frequently copying the same archivelogs ? Which sequences -- e.g. does it start at 1424 and continue to 1430 and then restarts at 1424 again , running in a loop ?
Oracle is not known to do that.
OR do you have a background / cron / scripted job that copies the archivelogs --- and is looping ?

ORA-16145: archival for thread# sequence# in progress

Hi,
10gR2 Database is configured in Dataguard maximum performance mode with no standby redo log file.
Archive log switching application on standby was working earlier but , it's stopped and unable to apply archive log on standby.For command 'recover standby database' it's giving ORA-16145: archival for thread#1 sequence# 5 in progress. The archive file is copied manually also ,but even though the problem persists.No archive log gap found for the secondary.the archivelogs are getting shipped properly.
Any suggestion? Thanks..

Hi,
FTPed the archive log file and started the standby recovery but ,
it gave error:ORA-01274: cannot add datafile

When started recovery after changing the parameter 'standby_file_management' to auto,

Hi All,
the database was a single one on 10gR2
i was doing a cold clone from one instance to another, when running recover
"recover database using backup controlfile"
it was always looking for sequence # 4 but in the archive log i only have #2 and #3.
i do not have sequence #4 anywhere on the system.
can you suggest a solution for this?

Hello,
When you Backup the database you should either:
1. Make a Cold Backup:
- Shutdown the original database and copy it's datafiles, redolog files, controlfiles, PFILE/SPFILE.
2. Make a Hot Backup:
- Set the original database in BEGIN BACKUP mode, then copy the datafiles, controlfiles, PFILE/SPFILE.
- Generate a last Archive log alter system switch logfile; and copy all the Archived log since the beginning of the Backup.
- Set the original database in END BACKUP mode.
In the first case, you don't need to make a Recovery.
In the second case you'll have to make a Recovery.
Else, you may use the DUPLICATE statement from RMAN:

Hope this help.

Update of jlabel does not happen when i wait for thread to finish (join())

gurus please help.
I have a main application which in actionevent calls a thread, that thread calls parent method to update ths status in jlabel, but when i use thread.join() to wait for process to complete, the jlabel does not get updated, please tell me how can i update the jlabel, i have to wait for thread to finish and during run i need to update the jlabel.
thanks

hi camickr and gurus:
here is the code:
notice after pressing the Process button, the label is being updated but its not working. I called the processnow() method directly and also by thread, but in thread I have to wait until it finishes using join() but still does not work, please help. Thanks

Wasn't there a way to display replies as threaded?

Didn't there used to be a way to display replies as threaded?
By that I mean:
Post
response 1
response 5, responding to 1
response 3, responding to 1
response 2, responding to top
response 4, responding to 2
rather than straight chronological so that you could easily see who people were replying to?
I can't seem to find that option anywhere, although I swear it used to be there. Am I imagining that?
Thanks in advance.

If in doubt you can always click on link by "in response to: <username>". Cleverly disguised as a user name, it actually takes you to the message that was responded to.

Problems with input for Threads

Please help, I don't know how to do further inputs
using the command line while threads are doing
their work.
Here's the code:
import java.io.*;
import javagently.*;
class Museum {
   Museum(int w) {
       walkmen = w;
       cash = 0;
       people = 0;

   // inform about new people
   while (walkmen < n) {
       try { wait(); }
       catch (InterruptedException e) {}
    people += n;
    System.out.println("New incommers are "+people);
    notifyAll();
synchronized void hire (int c, int n) {
   // If there are not enough Walkmen left
   // wait until someone at another counter
   // returns some and notifies us accordingly.
   // If the returns are not enough, we'll carry on
   // waiting.
   System.out.println("Counter "+c+" wants "+n);
   while (walkmen < n) {
       try { wait(); }
       catch (InterruptedException e) {}
   // Hire out the Walkmen and take the deposit.
   // Let the customers at this counter "walk away"
   // by relinquishing control of the monitor with
   // a notifyAll call.

   System.out.println("Replacing "+n);
   walkmen += n;

}Now, if somebody please take the time, look
at the code and help ?
Thanks in advance!

I tried to put BufferedReader in = Text.open(System.in);everywhere, even in the main method. It doesn't
matter where I put it. The threads are working and
I can't stop them to do further inputs in order to add the
number of new incoming people. I searched the forums,
tutorials, acticles but found nothing that gives me a hint
to what I can do to add more inputs. Most of Threads-
Examples use Random inputs, but there must be a way
to do it by myself using the commandline.
In fact I want to make a controlpanel (if neccessary by
GUI).
Can someone help?
