• DataGuard - why transport is LGWR is not good?

  Hello, I have new Dataguard questions.

  Recently I set up Active dataguard environmental laboratory in this way:

  tnsnames.ora (both)

  PRIM_DB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = ebstestfixdb) (PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = EBSTPF)))

  STBY_DB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = ebscapadb) (PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = EBSTB)))

  DB primary

  HOST = ebstestfixdb

  PORT = 1521

  SID = EBSTPF

  Watch DB

  HOST = ebscapadb

  PORT = 1521

  SID = EBSTB

  (1) in primary DB:

  $ sqlplus / as sysdba

  SQL > ALTER SYSTEM SET LOG_ARCHIVE_CONFIG = 'DG_CONFIG = (EBSTPF, EBSTB)';

  SQL > ALTER SYSTEM SET LOG_ARCHIVE_DEST_2 = 'SERVICE = COMPRESSION stby_db = ENABLE ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = EBSTB';

  SQL > alter system set log_archive_dest_state_2 = 'reporter ';

  SQL > alter system set log_archive_max_processes = 8;

  SQL > create pfile='/tmp/initEBSTB.ora' of spfile;

  $ cd $ORACLE_HOME/dbs

  orapwd file $ = $ORACLE_HOME/dbs/orapw$ ORACLE_SID password = jajah38

  SQL > select * from v$ pwfile_users;

  (2) copy password file, init.ora and tnsnames.ora on backup server

  (3) check the standby settings (keep the original SID main DB):

  log_archive_config ='DG_CONFIG = (EBSTPF, EBSTB)

  log_archive_max_processes = 8

  fal_server = "prim_db."

  db_unique_name = "EBSTB".

  Comment/remove LOG_ARCHIVE_DEST_2 and log_archive_dest_state_2

  (4) primary backup server backups

  $ scp ebstestfixdb: / u01/fra/EBSTPF/backup automatic/2014_10_06 / * / u01/fra/EBSTPF/backup automatic/2014_10_06 /.

  $ scp ebstestfixdb: / u01/fra/EBSTPF/backupset/2014_10_06 / * / u01/fra/EBSTPF/backupset/2014_10_06 /.

  (5) start standby DB and create duplicates

  $ export ORACLE_SID = EBSTB

  SQL > startup nomount

  RMAN $

  RMAN > Connect target sys/jajah38@prim_db

  RMAN > auxiliary connection.

  RMAN > target database double standby nofilenamecheck.

  Publish

  (1) in primary DB

  SQL > alter system set log_archive_dest_state_2 = 'enable '.

  Modified system.

  (2) standby DB

  SQL > alter database open;

  Database altered.

  SQL > alter database recover managed standby database disconnect;

  Database altered.

  To control this, I use Nagios Plugin http://labs.consol.de/lang/en/nagios/check_oracle_health/

  and this plugin displays a warning:

  WARNING - Dataguard managed the recovery status MRP0 process is WAIT_FOR_LOG. Journal of transport is LGWR.

  This is the code of this warning:

  ($self-> {log_transport}) =

  $self-> {channel}-> fetchrow_array (q {}

  Select decode (count (*), 0, 'ARCH', 'LGWR') as log_transport

  v $ managed_standby

  where client_process = 'LGWR.

  });

  ... etc...

  # OK if log_transport's ARCH, but not if LGWR

  $mrp_message. = sprintf "transport journal is % s.", $self-> {log_transport};

  If ($self-> {log_transport} eq 'LGWR') {}

  ... etc...

  So, why the newspaper transport LGWR is bad?

  And what's wrong in my setup?

  Thank you

  Fernando

  No, none of your options are suitable.

  If you have ARCH, then you don't need real-time applies. Option B ARCH transport if you are waiting for newspapers to be switched, archived and shipped. Unless you set archive_lag_target you have no real guarantee speed will be.

  You want to:

• would it not good to buy a 18-135 mm F3. 5 - 5.6) IS and a 70-300 mm F4-5. 6 IS both for my Canon 70 D?

  would it not good to buy a 18-135 mm F3. 5 - 5.6) IS + a 70-300 mm F4-5. 6 IS both for my Canon 70 D?

  Or a 18-135 mm F3. 5-5, 6) IS + a 55-250 mm F4-5. 6 IS VTS?

  Or with a 70-200? but budget then increases too.

  What do you recommend? i want to have fun soooon photograph animals you in Sri Lanka. Later, I would choose a macro to take the picture of bugs when I bike, trails and also the telescopic should I choose.

  STM 18-135 and 55-250 STM would create a nice kit the 70 d. STM 18-55 and 55-250 STM work as well but would need to change lenses more often.

  I recommend the 55-250mm IS STM on the 55-250mm IS or IS II because it is stronger and has an element before anti-rotation. This also applies to the versions of 18-55.

  I would not recommend the70 - 300mm IS because it is an older design with Micro-USM autofocus and a rotating front element, which can be frustrating when you use polarizing filter.  The 55-250mm IS STM is sharper than the 70-300mm autofocus STM is faster and quieter than the AF used in the 70-300mm

  If you can afford it, the 70-200mm L or 70-300mm L lenses are even better.

• What is a good lens to get to Montana

  I have a Canon T3i but you may want to rent a lens wide angle... I currently have 2 kit lens

  Do you take lots of pictures of wild animals?  Unless you are planning a trip with the express purpose of photographing wildlife, it is unlikely that you will capture the many wildlife shots by a big goal in your bag, just in case.  You're more likely to frighten the wild animals because they'll notice long until you spot them.

  The best wild shoots are carefully planned in advance, taking advantage of knowledge about particular wildlife you want to shoot.  For example, the construction of a blind near an area known for birds to gather, then occupying the blind before sunrise and stay inside of her for hours at a time.

  If you have a 70-300mm camera kit lens, you can be disappointed by the quality of the image when you take critical pictures, if you have not already visited.  With an APS - C camera, a focal length of 600mm would give you a lens equivalent 35mm to 960mm.  Without little practice, it will be difficult to capture sharp images in mothering the camera with a lens at this focal length.

  Long zoom can be expensive and cumbersome to wear.  They come with a learning curve, if you've never used one.  You would need to carry one to its ' own bag, or you would need a big backpack to carry it with the rest of your equipment.  Certainly, you would benefit to transport a fairly sturdy tripod, in order to support the weight of the super telephoto.  Outdoors, the wind can be a detrimental factor.  Wind can shake a light tripod, especially weighed down with a heavy load.

  If feel the need to perform a long zoom, I recommend one of the 70-200mm lenses and leave your zoom 70-300mm camera kit at home.  You can capture pictures of very good wildlife, casual without using a super telephoto.  Your APS - C body can transform a lens 70-200mm in 35mm equivalent of 112-320mm, which is close to the focal range of the Canon 100-400 mm zoom.

  One of the two Canon EF 70-200mm f / 4L lenses, with or without IS, might be a good choice.  I would put a priority to travel light and less so now in preparation for each scenario.  Don't forget, you can always crop a photo taken with a lens quality and always wind upward with a good result.

• Good lens for daytime lightning

  OK, since I got some really good (and much appreciated) tips here, I investigated.

  Since I was buying lenses for my Canon 6 d, which is a good lens for landscape, full moons, lightning (day and night) to get? I have a Studio of photography of Monument Valley April 2016. He put if this time because of the full moon and any activities of monsoon, so you can't beat the landscape! I already bought a Firefly sensor.

  I'm happy to get hands-on training with my camera to a professional!

  Any suggestions?

  I would jump ef 24-105mm F4 L IS.  It can be done in a 'white box' version, too.  It's a full-on the objective of 'L' pro. The 28-135mm is not, but it is a very nice lens for what it is.  It's really a good buy.  But this isn't a goal at the pro level.

  Any of these will "shoot the Moon" in great detail.  That will require a large telephoto lens.  In my humble OPINION, at least 400mm and 600mm preferred.

  «It was a Quantaray, but when he leaves with a focus...» »

  I have no doubt that!  I will be very frank and probably rude, I'm sorry, but there are only three manufacturers of lenses that you should consider.  Canon as a first choice, Tamron and Sigma second, your choice.  Stay away from any other brand.  IMHO, as always, of course.  There are very few, other, brand lenses that 'work' but not as a general rule.  They all seem to have problems.  Just don't go there!  It is not worth.

  Any lens you buy, it gives a good detailing, like B & H, Adorama, Best Buy, Amazon not!  Do not buy lens "kits".

  Just having the lens itself.

• EF 100-400mm f/4.5-5.6L IS USM

  Just bought an EF 100-400mm f/4.5-5.6L IS USM lens.  Is there anyone in this community of Canon that can offer backs or things on this goal.  Any information would be helpful.  Thank you.

  I'll assume you mean the version to push, but in general this applies to it & new. Use mode 1 IS for stationary subjects & mode 2 for panning. Use the limiter switch to speed the AF response on things that are further away & do NOT forget to re set during the filming of things inside the extreme limit of range switch controls. If you have not used a long lens before maintain high shutter speeds until you develop the right technique.

  If this is the version to push does too tighten the ring that locks / apply the voltage to the Canon zoom.

• I got a camera from Canon 650 EOS 35 mm with lens (70-210 mm EF 35-70mm EF, EF 50mm) and flash

  I got a camera from Canon 650 EOS 35 mm with lens (70-210 mm EF 35-70mm EF, EF 50mm) and Canon Speedlite 420EZ. I begin to use them to take pictures. I hope I can find a digito camera that will work with the device I already have. It was my father, and I want to use for the memories. I don't know much about photography (which I'll do it prbably take a class or two). If someone could give me help on what I could use to keep the lens I know 35mm body isn't worth much, but the memories. Can I use these lenses with a digital camera. I'm not rich and would like to buy something around 250 Beach (used or not)

  Thanks for your help in advance

  EF lenses will be monte on any modern interchangeable digital Canon camera except for the lower mirror that a person never see in stores.

  For your budget, you are a rebel used camera body. Search for a used T4i or a T3i. There is virtually no difference between the two; same, even autofocus sensor, etc. It will be a good camera to get into photography with.

• Canon EF400mm versus Canon EF100 - 400mm F4-f5.6. 5 F5. 6

  Hi people

  Having attended the MotoGP at Valalencia last week and using my 7 d with a 70-200 mm with 1.4 extender. I realized I need a longer lens for such events.  I was wondering what the objective would be better, that is to say the sharpness.  I know that the 100-400mm has the advantage of the zoom, but I don't want to lose the image quality if I can help it.

  This topic has been debated several times in two photography on the Net (POTN) and Fred Miranda (FM) for years with no clear winner. I suggest that you forget about choosing one or the other based on IQ only under ideal circumstances. You won't see the difference in what you're doing unless you have very good skills in pan. The first is slightly sharper, but then what? It limits what you can shoot because you can't keep changing position if you miss opportunities, some of which may be that 'money shot'. I shoot another form of action, and based on the expectations of those who look at a motorsports photos I strongly suspect that the ideal photos will have enough shutter speeds blurred wheels (or rays) slow & background but a rider & bike it very crunchy. Comply with these requirements will void all difference between the 2 lenses IQ wise 99% of the time.

  For my needs, the first (ANY first) would be unnecessary, even if I have them for free, and I rely on the lenses, considered less than ideal by most because they superzooms, BUT they do the job, & well. They may have the best IQ but they do get vaccinated and do it consistantly. Remember this isn't just the lens that captures the shot, it is the combination of the lens, the body, to know how to set variables in the body, and your ability to pan perfectly or hold it steady enough. One of these blow a little bit & the IQ is now less than what was possible when exacuted perfectly. You're shooting stationary no runners a tripod at a fixed distance throughout the day so consider all the variables of your previous trips to the track before buying.

• Why can I never get a good picture on my imac when using Skype?

  Why can I never get a good picture on my imac when using Skype?

  I use the free Skype to talk to my friend in China every week. They always see me on their computer or phone clearly, but I can never get a good video of them, clues why? I see a good image of myself, but never of them. I can't adjust the settings of the built-in camera because they are fixed. Is this my router modem, which is 8 years old now. What is causing this problem. If you look on YouTube there are hundreds and thousands of good quality webcam videos then why am I having this eternal problem year after year? I've got El Capitan OSX

  If they can see you clearly, the problem is not on your side - at least not in your Mac. Could be the router or you internet connection. Otherwise: https://support.skype.com/en/skype/mac/

• Display the Browse on Firefox is not good

  I am using a navigation button in my HTML, workng is fine, but on firefox-30 view of my button browse is not good, can someone help me to fix it in my code?

  Is it possible that this field is 'necessary' and what is called by a rule for admission: required in your CSS? This is not new in Firefox 30, but perhaps it was twisted (there are hundreds of variations in each version...). Otherwise, it is hard to imagine why you'd have a ring after using the control and not before.

• Why windows media player is not reading my DVD, and how do I install windows media player decoder using my drive from windows XP Professional?

  Media player from Windows

  Why windows media player is not reading my DVD, and how do I install the windows media player decoder using my disk of windows XP Professional

  FWIW... Win XP cannot natively recognize Commercial
  DVD video... it requires a DVD decoder. And... He
  is not a DVD decoder on your Win XP Pro drive.

  If you could play before commercial video DVD...
  do a system restore to a time before this started
  may be your solution.

  Or you could buy a DVD decoder at the following link:

  (FWIW... it's always a good idea to create a system)
  Restore point before installing software or updates)

  Info about DVD decoders:
  Plug-ins for Windows Media Player
  http://Windows.Microsoft.com/en-us/Windows/downloads/Windows-Media-Player/plug-ins

  Or you can download and use one of the following freeware
  media players:

  VLC Media Player
  http://www.filehippo.com/download_vlc/
  (works on XP/Vista/7)

  Media Player Classic Home Cinema
  http://MajorGeeks.com/Media_Player_Classic_Home_Cinema_d6213.html
  (works on XP/Vista/7)

  Or... you can try to download and install one of the
  Following codec packs.

  (FWIW... it is always preferable, if you create a system restore
  point before installing any software or updates).

  * Proceed at your own risk *.

  (1) K-Lite Codec Pack (full)

  Greg,

  Claes has pretty much nailed. You will do well to spend time to learn how Lightroom works. He is not like most software that you've used before, and if you don't understand what it does and how it does, you stand a good chance of losing your images.

  Try googling 'Lightroom tutorials' or 'get started in Lightroom. It's not rocket science, but it's different.

• Why the iPhone 6plus will not open photos app on mac pro for IOS 10 update.

  Why the iPhone 6plus will not open photos app on mac pro for IOS 10 update.
  A message appears on the iphone asks you to trust the computer it is attached (mac pro 10.10.5)

  You type 'Confidence' and nothing happens. the photos on mac app publishes this message.

  This Mac not yet have been granted access to the media on 'my iPhone '. To import media to this Mac, press 'Trust' on 'my iPhone '. You must first unlock the device.

  This actually solved for me after going to settings, General, reset, reset the location and privacy... and then plug in the unit and pressing the trust... hope that works for others.
