Hello
in 10g,.
I have this alert in DB control homepage:

I do any action/correction?

Thank you.

If your user name is happy, then you need not to do anything. If you want to analyze the details, thanks for posting your database AWR report.

Event class Metrics - database time spent waiting - 'competition '.

New 10g server and configured Enterprise Manager. Only, I use it and EM is connected at the moment. No other activity

Main window of the EM's needle suite msg all the time:
Metrics "database time spent waiting (%) "is 100 for the class of events 'competition '.

Through document manager Metrics (to make sense of these alerts) and querying the v$ system_event I could see the following:

SUBSTR(EVENT,1,20)   SUBSTR(WAIT_CLASS,1, TIME_WAITED AVERAGE_WAIT TOTAL_WAITS
os thread startup     Concurrency     3718        17.21         216

-Examines the views to wait for the right way to investigate the matter? or any other way to follow this?
That would indicate the high value in "starting thred os" (or even not at all, it is OK)

Hello

When start Enterprise Manager in Oracle 10 g, I have the following warning:

'Database time spent waiting (%) "represent 100 for the class of events 'competition '.

I'm new to the topic of listening, what I do with the warning?

Are there conclusions ADDM OEM homepage? If so, click it and let ADDM say the cause of competition and let make you a recommendation. If this is not the case, go to the ADDM (Central Advisor-> ADDM) page and click 'Run ADDM to analyze current performance of proceedings'. It then (probably) will give you findings and recommendations.

Time Machine - an exclusion different backup for the backup drives different time machine

I hope someone can help me.

For these past years, I used 2 Time Machine backups to keep all safe. I have 1 backup x who lives at home and is 3 times the size of my disk. I also have a second drive of laptop that I travel with, which is partitioned to give a little time machine backup, more than 1.5 TB of "overflow storage (for movies, video files, etc).

Recently however, I realized that my "storage of listening" actually contains a large amount of data I wouldn't lose (especially the photos of my children because they were born), so now I want to save this drive as well.

If my ideal situation is to have a huge drive I leave at home. This contains backups of the computer AND 'excess of storage' backup. It's pretty simple to implement.

But can someone tell me if my trip backup, will try also to the other partition of the backup drive? And if so, is there anyway to give different time machine backups different exclusions.

Hope that makes sense and hope that someone can help me.

Thank you
John

You will need to manually change the exclusions when you going on a trip. There isn't a way to change automatically.

Hello

1. which version of the operating system is installed on the computer?

If you use Windows 7, try the methods below and check if the problem persists.

Method 1:

Perform the disk check to check and fix bad sectors on the hard disk.

Note:

Running chkdsk on the drive if bad sectors are found on the disk hard when chkdsk attempts to repair this area if all available on which data can be lost.

Method 2:

Download and run a full scan of the system using Microsoft Safety Scanner to detect any problem related to the Virus/Malware.

Help the passage of the document class for the class of database!

Hello comrades!
I thought that I ve solved that problem, but I was wrong
I created a movieclip with a star. Then I create a document class and I named it like Main.as.
In this document class that I wrote:
```
package 
{
     import flash.display.*;

     public class Main extends MovieClip
     {
          var st:star=new star();

          public function Main()
          {
               stage.addChild(st);
               st.x=20;
               st.y=30;
          }
     }
}
```
If I run this code, I will get a star on the stage in the x direction and y positions.
Now, I want to drag the star with the mouse and drop it anywhere on the stage. After the fall, the star must return to its original position.
To achieve this, I create a new AS3.0 class. I named it DragDrop.as, and I linked to the movieclip as the baseclass.
Inside this category I wrote:
```
package 
{
     import flash.display.*;
     import flash.events.MouseEvent;

     public class DragDrop extends MovieClip
     {
          var x_origin:Number;
                var y_origin:Number;
                public function DragDrop()
          {
                        x_origin=this.x;
                        y_origin=this.y;
                        trace(x_origin);
                        trace(y_origin);
               this.addEventListener(MouseEvent.MOUSE_DOWN,drag);
          }
          function drag(evt:MouseEvent):void
                {
               this.startDrag();
          }
     }
}
```
I m not posting the code here, but you can easily see that the use of variable I m x_origin and y_origin to keep the original position of the clip.
I'll use them to bring star back in its original position.
The problem is that instead of being respectively 20 and 30, retracing their I see that they are both ZERO.
So, when I drop the star, instead of going to x = 20, y = 30 back to x = 0 and y = 0.
I ve for the position of Star compared to the scene, but I can´t find anyway!
Could you help me?
Thanks in advance!
Best rgds
Eduardo

I think I see... you have:
```
 stage.addChild(st);               st.x=20;               st.y=30;
```
for the init works in the star before set the position... so still 0,0. You can set the x, y front sets addChild... or you can change your star class to accept the position in the constructor. And then you'd like: var st:star = new star (20,30);

Should I wait until the end of the execution time of the query for the execution plan?

Hello Experts,
I want to see the execution plan of the query below. However, it takes more than 3 hours. Should I wait all the time to see the execution plan?
Note: EXPLAIN PLAN for does not work. (I mean that I do not see the actual line number, etc. with EXPLAIN the PLAN of market)
You can see the output of the execution plan when I canceled the execution after 1 minute.
My first question is: what should I do to see the execution plan for queries running out of time time?
2nd question: when I cancel the query during execution in order to see the execution plan, will I see the specific plan of execution or erroneous values? Because the first execution plan seems inaccurate, what do you think?
question 3: why EXPLAIN the PLAN for the clause does not work? Also, should I use EXPLAIN the PLAN of the clause to this scenerio? Can I see the result of running for long time without her queries?
Thnaks for your help.

Randolf,

I don't understand. What you hear from the above statement that you mean A-lines and E will be incorrect, but the ratio between them remain the same. Therefore, you can deduct the bad things by comparing the differences.

Thus, A-lines always give a wrong result for cancellation of queries, isn't it?

You say here that I canceled a query after about 5 minutes, and looking at the statistics of content (RowSource) I can already say the following:

1. the estimation of cardinality of T1 is far - the optimizer estimated 100 lines, but it actually generated more than 57000 lines when the query was cancelled. If this definitely seems like a candidate at the origin of the problems

2. the query has spent most of the time in search of random table T2

So while it is true that I don't know final A-lines of this cancelled query information, I can still say a lot of this and begin to deal with the problems identified so far.

(5) I've created 4 standby redo logfiles (/oraredo/testdb/stby01.log stby02.log stby03.log stby04.log)
(6) I do RMAN backup (database and archivelog) on the site of relief only.
(7) I want to use this backup for full restore of the database on the primary database.
He is a DR test to simulate the scenario that has lost every primary & Eve total servers.
Here is how to save, on the database pending:
(1) performance 'alter database recover managed standby database Cancel' to ensure that compatible data files
(2) RMAN > backup database;
(3) RMAN > backup archivelog all;
I got elements of backup and copied to primary db Server something like:
/Home/Oracle/backupset/o1_mf_nnndf_TAG20151002T133329_c0xq099p_.BKP (data files)
/Home/Oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.BKP (spfile & controlfile)
/Home/Oracle/backupset/o1_mf_annnn_TAG20151002T133357_c0xq15xf_.BKP (archivelogs)
So here's how to restore, on the main site:
I clean all the files (data files, controlfiles oder all gone).
(1) restore spfile from pfile
RMAN > startup nomount
RMAN > restore spfile from pfile ' / home/oracle/pfile.txt' to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';
(2) modify pfile to convert to db primary content. pFile shows below
*.audit_file_dest='/opt/Oracle/DB/admin/testdb/adump '
* .audit_trail = "db".
* full = '12.1.0.2.0'
*.control_files='/oradata/testdb/control01.ctl','/orafra/testdb/control02.ctl'
* .db_block_size = 8192
* .db_domain = "
*.db_file_name_convert='/testdb/','/testdb /'
* .db_name = "testdb".
* .db_recovery_file_dest ='/ orafra'
* .db_recovery_file_dest_size = 10737418240
* .db_unique_name = "testdb".
*.diagnostic_dest='/opt/Oracle/DB '
* .fal_server = "stbydb".
* .log_archive_config = 'dg_config = (testdb, stbydb)'
* .log_archive_dest_2 = "service = stbydb SYNC valid_for = (ONLINE_LOGFILE, PRIMARY_ROLE) db_unique_name = stbydb'"
* .log_archive_dest_state_2 = 'ENABLE '.
*.log_file_name_convert='/testdb/','/testdb /'
* .memory_target = 1800 m
* .open_cursors = 300
* runoff = 300
* .remote_login_passwordfile = "EXCLUSIVE."
* .standby_file_management = "AUTO".
* .undo_tablespace = "UNDOTBS1.
(3) restart db with updated file pfile
SQLPLUS > create spfile from pfile='/home/oracle/pfile.txt'
SQLPLUS > the judgment
SQLPLUS > startup nomount
(4) restore controlfile
RMAN > restore primary controlfile to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';
RMAN > change the editing of the database
(5) all elements of backup catalog
RMAN > catalog starts by ' / home/oracle/backupset / '.
(6) restore and recover the database
RMAN > restore database;
RMAN > recover database until the SNA XXXXXX; (this YVERT is the maximum in archivelog backups that extends beyond the scn of the backup of the data file)
(7) open resetlogs
RMAN > alter database open resetlogs;
Everything seems perfect, except one of the file log roll forward pending is not generated
SQL > select * from v$ standby_log;
ERROR:
ORA-00308: cannot open archived log ' / oraredo/testdb/stby01.log'
ORA-27037: unable to get file status
Linux-x86_64 error: 2: no such file or directory
Additional information: 3
no selected line
I intended to use the same backup to restore primary basic & helps record traffic and the downtime between them in the world of real output.
So I have exactly the same steps (except STANDBY restore CONTROLFILE and not recover after database restore) to restore the database pending.
And I got the same missing log file.
The problem is:
(1) complete alert.log filled with this error, not the concern here
(2) now repeat it in real time apply won't work since the Party shall LGWR shows always "WAITING_FOR_LOG."
(3) I can't delete and re-create this log file
Then I tried several and found:
The missing standby logfile was still 'ACTIVE' at present RMAN backup was made.
For example, on db standby, under Group #4 (stby01.log) would be lost after the restoration.
SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;
GROUP # SEQUENCE # USED STATUS
---------- ---------- ---------- ----------
4 19 ACTIVE 133632
5 0 0 UNASSIGNED
6 0 0 not ASSIGNED
7 0 0 UNASSIGNED
So until I take the backup, I tried on the primary database:
SQL > alter system set log_archive_dest_state_2 = delay;
This was the Group of standby_log side Eve #4 was released:
SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;
GROUP # SEQUENCE # USED STATUS
---------- ---------- ---------- ----------
4 0 0 UNASSIGNED
5 0 0 UNASSIGNED
6 0 0 not ASSIGNED
7 0 0 UNASSIGNED
Then, the backup has been restored correctly without missing standby logfile.
However, to change this primary database means break DataGuard protection when you perform the backup. It's not accept on the production environment.
Finally, my real questions come:
(1) what I do may not do on parameter change?
(2) I know I can re-create the control file to redo before delete and then recreate after. Is there any simple/fast to avoid the standby logfile lost or recreate the lost one?
I understand that there are a number of ways to circumvent this. Something to keep a copy of the log file waiting restoration progress and copy up one missing, etc, etc...
And yes I always have done no real-time applies "to the aid of archived logfile" but is also not accept mode of protection of production.
I just want proof that the design (which is displayed in a few oracle doc Doc ID 602299.1 is one of those) that backs up data backup works effectively and can be used to restore the two site. And it may be without spending more time to resume backups or put the load on the primary database to create the database before.
Your idea is very much appreciated.
Thank you!

Hello

1--> when I take via RMAN backup, RMAN does not redo log (ORL or SRL) file, so we cannot expect ORLs or SRL would be restored.

2nd--> when we opened the ORL database should be deleted and created

3rd--> Expecting, SRL should not be an issue.we should be able to do away with the fall.

If you do, you can recreate the controlfile without waiting for redo log entry...

If you still think it's something is not acceptable, you must have SR with support to analyze why he does not abandon SRL when controlfile_type is "underway".

Thank you

Wait for the event begins with SQL * Net message from client-time wait 178577 units
Hello

I'm watching events waiting for a request from long time in TOAD.
I start the query on an instance of TOAD, and open the browser to log on to another instance.
But I am surprised to see that in "TOtal expected" on the RIGHT part->
SQL * Net message from client is the longest time and is already - > 178577 units while I just to start the query.

Considering that, in the current waiting she shows DB file scattered read correctly for a few seconds.

Please suggest.

Hello. No explanation for this... :-(

Hello

people work here, you don't know?
I think Tom Kyte explains it well enough. This wait event is linked to your session database waiting for the guest to say to do something.

So it is not related to the database, but to your application.
Also as it is a wait of session event you might have had your session inactive for some time (do nothing)

If you want to check the waiting events correctly I suggest using tkprof and start a new session in SQL more as shown by Tom Kyte in the link I posted.

Then, run your query in sqlplus setting track and pull it out as soon as your statement is completed.
that is to say:
```
-- myest.sql
alter session set events '10046 trace name context forever, level 12';
SELECT ... -- your query here
exit
```
Run in sqlplus in this way:
```
sqlplus user/password@db @mytest.sql
```
Then check with tkprof.

Kind regards.

Minimum time to wait in the loop of reading series

Hello

I would like to ask if it is possible to read data from a serial port loop each 17ms? If so, how to read Serial and it management loop set.

I'm the Arduino Uno card reading that can run on up to 115200 baud rate of kbs. Arduino sends each integral 17ms (0-3). Now, I can't read them separately (each part one by one, I get numers as 123, 231, 12, instead of 1, 2, 3 etc.), but this may be due to other stuff I do in the loop. I elaborate more on my VI later - now I would like to know if it is possible using LV 2011 + VISA read serial number of each 17ms. What bothers me the most is that I saw many times on this forum that people suggest of don't not to go below 10ms timeout in the Serial reading loop (same base series Read and Write provided in examples of or). If ms waiting loop of x, where x is 17ms divider?

You hear that you read whole and not full? Send you one byte or more? If it is a single byte, then just define it as the number of read. Do not put in any function wait and do not use the VISA to the Serial Port bytes. Playback VISA will be automatically terminated when one reads a single byte. You send a terminator after the number? Waiting in the example has nothing to do with a constant data stream reading and with a terminator is completely useless.

What to do for the main database when a physical database ensures converts a standby time of the snapshot

Hello
Need of the primary database to implement the flashback database when a physical database ensures converts a standby time of the snapshot? Or something to do with the primary database? I find some documents this work to allow the return of flame for the primary databases, but I think that he didn't need to do.
Thank you
Best regards.

I did recently, I have not configured flashback on primary, only configured in the standby mode. I converted the standby database and restored the changes after the test. Primary database continued to send archives to the standby site. Instant once converted into sleep mode, as mseberg mentioned overlaps with the sync state after starting MRP.

Necessary to define the database time zone differs from the OS

We have a database of who currently resides in New York. Let's move to another server that resides in London. This is a problem, because each date which is currently in the time base is New York time, but after the move, all the new data that created time will always be time to London. We do not want users to have to remind any date preceding the date of move, will idle 5 hours if we would like to do is to have the database always on time in New York despite the BONE being London time. The server will be shared with other applications for the operating system time zone will have to remain with London time. The database will only have data for our application. So is there a setting of database that we can use to set the time zone database is different from the operating system time zone? The database is currently 10 GB but is promoted as part of the move to 11 g.

What is the data type of the column? If the date or timestamp, then there is no time zone stored with the data. If timestamp with time zone, then the time zone of the data remains the same regardless of the time zone database and operating systems.
