Does a normal view write to any log i.e archive or undo log
Hi ,
can i check if a normal view writes to the archive or undo log ?
e.g
select a.* , b.* from A , B
tks & rdgs
SELECT statements, including those that are selecting views, aren't making any data changes, so there would be no reason to generate UNDO or REDO log entries. There would be nothing to undo or to redo.

Logs are not archived at Standby site on same server
Hello all,

Next log sequence to archive in Standby Database (RAC Dataguard Issue)
Hi All,
I just had implemented Data Guard in our server. My primary Database is RAC configured, but it is only single node. The other Instance was removed and converted it to Developement Instance. For the reason I kept the primary as RAC is when I will implement dataguard, my Primary Database is RAC with 7 nodes.
The first test is successful, and I was able to "switchover" from my primary to standby. I failed in the 'FAILOVER" test.
I restore my primary server and redo the setup.
BTW, my standby DB is physical standby.
When I try to switchover again and issue archive log list, below is my output.
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 38
*Next log sequence to archive 0*
Current log sequence 38
SQL> select open_mode, database_role from v$database;
OPEN_MODE DATABASE_ROLE
MOUNTED PHYSICAL STANDBY
===============================================
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 38
*Next log sequence to archive 38*
Current log sequence 38
SQL> select open_mode, database_role from v$database;
OPEN_MODE DATABASE_ROLE
READ WRITE PRIMARY
In my first attempt to switchover before I failed in "FAILOVER" test, I also issue +archive log list+ in both primary and standby database, and if I remember it right, next log sequence on both should be identical. Am I right on this?
Thanks in Advance.
Jay AOr Am i just overthinking on this?
Is dataguard only looking for the current and oldest log sequence? -
Next log sequence to archive is different
Hi,
I have doubt on standby (DR) concept.
I can see that in my standby database next log sequence to archive shows 0.
Is this ok or something is wrong?
PRODUCTION

Short answer no nothing is wrong.
Its the same on mine :

SQL> I use v$archived_log to check mine standby :
SELECT name as STANDBY, SEQUENCE#, applied, completion_time from v$archived_log WHERE DEST_ID = 2 AND NEXT_TIME > SYSDATE -1;Against my Primary I get the last log :
select max(sequence#) from v$archived_log where NEXT_TIME > sysdate -1;Data Guard has a set of v$ views to check results, 8archive log list8 isn't so good since with Data Guard you have two copies of the same database in different roles.
Another query I like is : (Run on the standby)
select process, status, sequence#, block# from v$managed_standby;The Oracle doc E10700-02 has several example in chapter 9 "Monitoring Primary, Physical Standby, and Snapshot Standby Databases"
Also section "3.2.7 Verify the Physical Standby Database Is Performing Properly"

How do I manually archive 1 redo log at a time?
The database is configured in archive mode, but automatic archiving is turned off.
For both Oracle 901 and 920 on Windows, when I try to manually archive a single redo log, the database
archives as many logs as it can up to the log just before the current log:
For example:
SQL> select * from v$log order by sequence#;
GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
1 1 14 104857600 1 NO INACTIVE 424246 19-JAN-05
2 1 15 104857600 1 NO INACTIVE 425087 28-MAR-05
3 1 16 104857600 1 NO INACTIVE 425088 28-MAR-05
4 1 17 512000 1 NO INACTIVE 425092 28-MAR-05
5 1 18 512000 1 NO INACTIVE 425100 28-MAR-05
6 1 19 512000 1 NO CURRENT 425102 28-MAR-05
6 rows selected.
SQL> alter system archive log next;
System altered.
SQL> select * from v$log order by sequence#;
GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
1 1 14 104857600 1 YES INACTIVE 424246 19-JAN-05
2 1 15 104857600 1 YES INACTIVE 425087 28-MAR-05
3 1 16 104857600 1 YES INACTIVE 425088 28-MAR-05
4 1 17 512000 1 YES INACTIVE 425092 28-MAR-05
5 1 18 512000 1 NO INACTIVE 425100 28-MAR-05
6 1 19 512000 1 NO CURRENT 425102 28-MAR-05
See - instead of only 1 log being archive, 4 of them were. Oracle behaves the same way if I use the "sequence" option:
SQL> select * from v$log order by sequence#;
GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
1 1 14 104857600 1 NO INACTIVE 424246 19-JAN-05

Is there some default system configuration property telling Oracle to archive as many logs as it can?
Thanks,
DGRThanks Yoann (and Syed Jaffar Jaffar Hussain too),
but I don't have a problem finding the group to archive or executing the alter system archive log command.
My problem is that Oracle doesn't work as I expect it.
This comes from the Oracle 9.2 online doc:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_23a.htm#2053642
"Specify SEQUENCE to manually archive the online redo log file group identified by the log sequence number integer in the specified thread."
This implies that Oracle will only archive the log group identified by the log sequence number I specify in the alter system archive log sequence statement. However, Oracle is archiving almost all of the log groups (see my first post for an example).
This appears to be a bug, unless there is some other system parameter that is configured (by default) to allow Oracle to archive as many log groups as possible.
As to the reason why - it is an application requirement. The Oracle db must be in archive mode, automatic archiving must be disabled and the application must control online redo log archiving.

version 5 loaded on windows 7. all went well for a while. one day while using, ratio of normal screen doubled in width; i.e. half the page disappears off the screen to the right (on a wide screen). when full screen mode applied, ratio is fine. it only happens in normal view, which is the usually prefered option. I cannot determine any means within the program to resize the normal screen. nothing else is affected, only mozilla firefox in normal view. not that when program is opened from keyboard the page is correct for a moment, then enlarges the width with 1/2 page dissappearing.
This issue can be caused by the Babylon Toolbar 1.1.8 extension
*https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

i accidentally tapped my iPhone 6 and everything got huge on my screen. now i can't even log onto my phone because everything is so big on the screen. how do i get it back to normal view, so i can log on?
i googled for answer to resolve the zoom problem. all the anwers just told you to read links but didn't tell how to fix the screem back to normal then it can be able to go to Setting to fix the zoom funciton. HOWEVER, I accidentally found the solution myself by using a fingers or more
to draw circles clockwise on the screen....it will reset it normally. I spent hours trying to go diagonally, compressively still didn't work. -
my ipad with retina eye updated to IOs 7 not able to boot ....the normal way of pressing the sleep/wake button and the home button does'nt work....any ideas i think that IOs 7 is a crap cos form the time i loaded it it was shaky...now my ipad is dead
If it is one year old minus one day it is still under warranty. If it is more than a year since you purchased it then yes, the warranty has expired.
Millions of iPads have been sold. Most continue to function long after their warranty has expired. Check the many requests about updating the iOS on the original iPad on these forums and you'll see that there are many iPads still working after three years. My iPad 2, which I had for over two years is still working well for my son in law who took it over from me when I bought a new one.
Given that there will always be a few iPads that fail early. Most of those will be covered under warranty. But some will fail after the warranty has expired and before the owner expected it to. I'm sorry to hear that you are in this category. Take your iPad to an Apple store and have it looked at. They will provide you with alternatives, one of which is to purchase a like model to the one that failed at a discount. You can then know your options and make the best choice for you. -
Reading Floating Point PLC5 Registers Kills my ability to write to any register
When ever I create an object that reads a PLC5 Floating Point Register(F8:5),it kills my ability to write to any other PLC register. The problem only shows up with Floating Point registers. If I use integer registers (N7:121 etc.)I can read/write fine. It also severely slows down my normal driver scan update time. Even though it is set to scan every 30 seconds, I may only get an update every few minutes. Anyone else ever run into this? Thanks in advance!
Hi,
It might be helpful creating a log file to monitor com port activity.
Here's the Knowledgebase article about it.
http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/cac576863ff648a186256b5900794761?OpenDocument
Another way to check the serial port activity would be using "portmon"
software available at

I hope this helps.

I recently upgraded from iPhone 5s to iPhone 6 Plus. When I go to view my photos, all of them are blank and at the bottom, it says "Downloading..." It has been this way for two days, but hasn't really downloaded any of my photos yet. Does it normally take this long? Is there anything I can do to speed it up?
IF you are getting no messages period - not just no iMessages - then it is very likely a carrier issue. It is AT&T and not the phone. SMS travels via the carrier wave used to make phone calls - iMessages use data and go through Apple servers as you know
If you are getting no messages at all - then I wonder if your cell service is ok or if you are in an area of strong signal - then does your SIM card need to be looked at -
Pasteboard color in Normal View mode
I know I can change the color of the pasteboard when in preview mode, but does anyone know of a way I can change the color of the pasteboard when in normal view? Or a way to have white-filled objects/text pop-up off the white pasteboard?
(The white is great, but when working with a lot of reversed copy, dealing with frame edges across multiple text boxes can become confusing and having to switch between color and white text can be tedious)This is a total workaround:
Go to the master page for the document.
Draw a frame that covers the whole pasteboard.
Draw a smaller frame that is slightly larger than the pages for the master.
Select the two frames that you just drew.
Choose Object > Paths > Make Compound Path.
Apply a light color to this object. This object will color the pasteboard for all pages that use this master. Duplicate for any other pages.
Optional steps
Put this object on its own layer. This allows you to turn this color on or off.
Set the layer as non-printing. This object shouldn't print because it doesn't touch the pages, but if you're paranoid, set it not to print.
Save as a snippet that can be dragged onto other documents. -
Hi guys I just bught a
WVC210 Wireless-G PTZ Internet Camera
I need to install it so that I can view it from any where in the world. I have no Idea how to do this.
I would like if some one can send me a video tutorial on how to do it.
I have a website that I am runing so I guess I can use that if I need something like Hosting and Domain things.
I want to know if it is posible that I can some how configure it so I can view the camera on one of my websites page.
For exaple: www.example.com/mycamera???
If not well I would love to here the options I have.
Thank you very much in advance!Rogerio,
I have never seen a router like you have and I wouldn't dare advise you about changing the settings. It appears that it is a router/modem that was provided by your ISP. If this is the case, I recommend that you call your ISP and ask them for Port Forwarding assistance. You need to forward port 80 to the LAN IP address of your camera. The LAN IP address of your camera is the IP address that you use to log into the web interface. You should not need to change any settings on the camera. After you have had the ISP help you forward the port to the camera, go to ipchicken.com and you will see your WAN IP address. Write that address down and then go to a remote location and type it into your web browser. You should get the login page of the camera. Note that your WAN IP is subject to change. You can ask your ISP to provide you with a static IP address which will be an additional charge each month but your IP address will not change. Another option is to use a service such as dyndns to create a unique URL that you can use to access the camera remotely even if your WAN IP address changes. We can discuss that after you get access to the camera if you have further questions. -
