• Model maching class of regular Expression to validate the alphanumeric string

  Hello
  MY version of DB is Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Production 64-bit
  
  I wanted to use the model maching given by oracle classes to check whether a given input string is alphanumeric.
  
  Documentation Oracle 10 g said about classes like [: digit:], [: alnum:] and many others.
  
  http://www.DBA-Oracle.com/t_regular_expressions.htm
  
  However these classes seems not work with my version of DB.
  
  Can someone tell me the DB version in which these classes work?
  
  Here is the code I use to validate an input string.

  Hi knani
  I need to check whether the input string is alphanumeric.

  That's why "ABC" all entries as '1234', '123ABc', must return true.

  Also can the alphanumeric string contains characters that are available on the keyboard which can be seized of it.

  Concerning
  Arun

  I just read your requirement "all printable characters.

  Try:

  select regexp_like('string','^[[:print:]]$') from dual
  

  to get only the records that have only printable characters.

• On my local disk, there is all about random alphanumeric files

  On my hard drive, just in C:\ there are alphanumeric files such as:

  fce1ea13edcf0b4f57beeb03fc

  e4d9e70c592075e7cc7d1e5255

  b634835a5f351fd668ed1f422678c0

  and the other six files randomly. What are these files? And is it OK if I remove them?

  How do you know they have something to do with the BIOS?
   
  Are you just getting DELETE happy? ;-)
   
  If you don't know what something is - Google it.  Unless you run low space - leave would be.  It should not be difficult to navigate in any case.  When you browse is * not * where will the regular users (even the developers normally).  You try to clean things, there is probably no need cleaning. ;-)
   
  I think you can go too delete happy and when people get like this - I have two questions:
   
  (1) how are your backups?  Not just backups "your stuff" with regard to the files you created, but your installation media, product, emails, contacts, music, photos keys, etc.?
  (2) why you delete everything?  Do you need the space or you're going a little OCD?  Better, some things are left to themselves.  What may be safe for a person to delete could be disastrous for another.
   
  How much hard drive space you have free?  How much do you have in total?  What is your backup plan?

• Equium A60-157: random alphanumeric characters

  Can anyone tell why, then of the seizure of the numbers get us random numbers additional displayed - same thing happens with letters. Makes life very difficult especially for the passwords! Maybe more noticeable after you have enabled hibernation in Power Options (using XP Home on A60 - 157).

  Thank you very much.

  Hello

  Well, I m not 100% sure, but it could be an unstable cable or something wrong wit keyboard connectors.
  In this case, I recommend to ask the service partner Toshiba for a diagnostic test.
  I m sure it can give you correct information on fault.

• function to check the alphanumeric string of pan card

  for example a pan card number ' * AAFCQ4563U *'
  
  I wan to create a function that checks the first 5 digits as capital alphabets and total length of the string is 10.
  
  Published by: arnaud August 2, 2011 22:45

  Hi Arnaud,.

  As already mentioned by Barend, you should always put the version number that you are using. You can use the REGEXP_LIKE expression to get the desired result. The TANK contains also the first 5 digits as the alphabets, nest 4 numbers and the last one like alphabet still once, then you should check the chain rest as well.

  You can try. It works fine on Oracle 10 g and Oracle 11 g version 10.2.0.4 and 11.2.0.1.

  CREATE OR REPLACE FUNCTION validate_pan_num (pan IN VARCHAR2)
     RETURN VARCHAR2
  AS
  BEGIN
     IF (REGEXP_LIKE (pan, '[A-Z]{5}[0-9]{4}[A-Z]{1}') AND LENGTH (pan) = 10)
     THEN
        RETURN 'true';
     ELSE
        RETURN 'false';
     END IF;
  END;

• An alphanumeric string

  Good day to all,

  I have what I hope to be a simple question. I have a table that I'm storing Latitude and longitude in. The current format for each example is N432301 for the Latitude and
  W0844150 for Longitude.

  I need the output formatted to

  N 43-23-01 for Latitude

  and

  W-84-41-50 of Longitude.

  GMoney says:

  Greg,

  I ran this by using the following:

  {code}

  with xx (lat select 'N402456', 'W1203926' double lon)

  Select substr (lat, 1, 1) | '-' || substr (lat, 2, 2) | '-' || substr (lat, 4, 2) | '-' || substr(lat,6,2) latitude,

  substr (Lon, 1, 1) | '-' || substr (Lon, 3, 2) | '-' || substr (Lon, 5, 2) | '-' || longitude substr (Lon, 7, 2)

  XX.

  {code}

  and the result was:

  LATITUDE	LONGITUDE
  N 40-24-56	W 20-39-26

  which is false, because in this case the lon was 3 Tank 2 after abandoning the '0' of the 084.

  That's why I started with "Really need rules to ensure that it is accurate"

  Seriously, if you don't give us some good features, you can't complain that much if we get not all your requirements in the first inning.

  If you find a first 3 digits, no problem...

         substr(lon,1,1) || '-' || substr(lon,2,3) || '-' || substr(lon,5,2) || '-' || substr(lon,7,2) longitude
  

  If you need to drop the 0 on the previous example (still guessing, because you have not given any real rules)

         substr(lon,1,1) || '-' || to_char(to_number(substr(lon,2,3)),'fm999') || '-' || substr(lon,5,2) || '-' || substr(lon,7,2) longitude
  

  but at this point, Mike reg exp's scheming probably work better

  Laughing out loud

  [edit]

  Just for completeness:

  with xx as ( select 'N432301' lat, 'W0844150' lon from dual union all
               select 'N402456'    , 'W1203926'      from dual
   )
  select substr(lat,1,1) || '-' || substr(lat,2,2) || '-' || substr(lat,4,2) || '-' || substr(lat,6,2) latitude,
         substr(lon,1,1) || '-' || to_char(to_number(substr(lon,2,3)),'fm999') || '-' || substr(lon,5,2) || '-' || substr(lon,7,2) longitude
    from xx;
  

  LATITUDE LONGITUDE

  ---------- ------------

  N 43-23-01 W - 84 - 41 - 50

  N 40-24-56 W - 120 - 39 - 26

  2 selected lines.

  Great demands, comes with excellent results.

  Bad conditions, just mediocre results

• How to implement Natural Order String sorting in ADF

  I have a table/content tree, in which a columns have alphanumeric string. I want to sort this column in the natural sort order.
  By default in the ADF, sorting of alphanumeric strings is ascii.
  
  Default sort
  -----------------
  dev10
  dev215
  dev30
  
  Natural sort
  --------------------
  dev10
  dev30
  dev215
  
  How can I go about it?
  
  Thank you
  Rahul

  You can do within the db using the order by clause

  select * from xxxx order by to_number(regexp_substr(data, '[0-9]+'))
  

  XXXX is the name of your table and the data is the name of the column to sort.

• Reading the part of a string

  I have a table with a column "otname."
  Table1.otname contains several lines of alphanumeric string that resembles the following sample data:
  
  11.10.32 * 12 *. U.A.F.3.2.21.249.1
  2001.1.1003 * 8281 *. A.THE. PAINVIN
  2010.1.1003 * 8261 *. A.THE. B.B
  
  I want to read the fourth number in each chain (part of the string in bold) and write a query in Oracle 10 g
  to read its description stored in another table. My dilemma is to write the first part of the query.i.e. Choose the fourth issue of each string in an array
  
  My second query will be something like this:

  select description_text from table2 where sncode = 8281  -- fourth part of the data sample in every string

  Thank you very much.
  
  novice

  Oops... I forgot to change that:
  Fixed query:

  SELECT   description_text
     FROM   table1, table2
    WHERE   SUBSTR (otname, INSTR (otname,'.', 1, 3)
                           + 1,
                           INSTR (otname, '.', 1, 4)
                                - INSTR (otname,'.', 1, 3)
                                - 1)
                                 = sncode
  

  This will return rows from your table if the sncode appears as the fourth string (delimited by '.') in otname. What is your requirement?

  Kind regards

• How can I perform a clean installation of Mac OS x for my iMAC, retina 5K late 2014 with drive of Fusion with the intact Recovery HD partition?

  How can I perform a clean installation of Mac OS x for my iMAC, retina 5K late 2014 with drive of Fusion with the intact Recovery HD partition?

  Pure how to install OSX on a Fusion drive and keep the recovery disc function

  These instructions assume that your iMAC partitions or file systems has been damaged and you want to restore to the way most efficiency with fusion drive and the recovery partition, similar to what was built in the factory.

  These instructions work for the iMAC, retina 5K end 2014 version comes with OSX Yosemite. The scores of major drive of the 128 G SSD and 3 TB of HARD drive has been configured as a logical drive (merger by car).

  WARNING: These instructions here are shared for interest only. Readers to take their own risk by following these instructions. The author is not responsible for any damage caused by following these instructions.

  This is the target disk partitions, and the configuration that we want to achieve.

  Disk0 is the 128 GB SSD - solid state drive and holds the start of the partition (disk0s3)

  Disk1 is the 3.0 to HDD - mechanical transmission and holds the Recovery HD partition.

  There are two EFI partitions to partition table GUID on both hard drives (disk0s1, disk1s1).

  Disk space remaining (partition disk0s2 and disk1s2) are used to create the disc of Fusion 3.1 to named "Macintosh HD".

  / dev/disk0 (internal, physical):

  #: NAME SIZE TYPE IDENTIFIER

  0: GUID_partition_scheme * GB 121,3 disk0

  1: disk0s1 EFI EFI 209.7 MB

  2: Apple_CoreStorage GB LVG 121.0 disk0s2

  3: disk0s3 Apple_Boot Boot OS X 134,2 MB

  / dev/disk1 (internal, physical):

  #: NAME SIZE TYPE IDENTIFIER

  0: GUID_partition_scheme * 3.0 to disk1

  1: EFI EFI 209.7 MB disk1s1

  2: disk1s2 Apple_CoreStorage TB 3.0 LVG

  3: disk1s3 Apple_Boot Recovery 650.0 MB HD

  / dev/disk2 (internal, virtual):

  #: NAME SIZE TYPE IDENTIFIER

  0: Apple_HFS Macintosh HD + 3.1 TB disk2

  Logical volume on disk0s2, disk1s2

  0D807F6E-FB7C-418F-AAF4-EF3EA3525D10

  Fusion unencrypted drive

  Here's how we do it.

  • A. clean reinstallation of Mac OS x.
  • 1. make sure that you back up all your data on the hard drive using Time Machine or other means. The following procedure will delete all data.
  • 2. create the OSX install USB, insert it to the MAC workstation.
  • 3. given that us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 4. in the menu at the top of the screen, select disk utilities.
  • 5. turn highlighted the volume of disk Fusion called "Macintosh HD." Click clear to clean.
  • 6. If his success, then go ahead to install OSX new to that partition, as usual.
  • 7. otherwise, if it does not, that means fusion drive has been damaged.
  • 8 follow the instructions below to fix it.
  • . B. Split disc Fusion in the physical hard disks
  • 1. Since us will be operated on the internal drive of the Mac trunk, assumes that we already have boot up OSX install USB drive (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3. on the screen of the terminal type:
  • Cs diskutil list.
  • You will see something similar to the screen below.
  • 4 copy the long string after Logical Volume and replace the UUID with it in the following command to delete the logical volume of the disc fusion (aka coreStorage of logical volume):
  • diskutil deletevolume cs UUID
  • For example:
  • diskutil deletevolume E59B5A99-F8C1-461A-AE54-6EC11B095161 cs
  • 5 copy the long string after the logical volume group and replace the UUID with it in the following command to remove the drive (aka coreStorage) fusion:
  • diskutil cs remove UUID
  • p. ex. diskutil cs remove E03B3F30-6A1B-4DCD-9E14-5E927BC3F5DC
  • 6. at this stage, the fusion drive has been deleted, and hardsisk SSD and mechanical hard drive will be reappear in diskutil or separate records.
  • 7. If step 5 or 6 takes more than 30 minutes to complete, this means that the fusion drive has been corrupted. You can follow the commands below to clear the table to partition the hard way. First command clears the SSD drive, second command erases the HARD drive.
  • The command does not return a response, after 1 minute, press Ctrl + Z to complete orders. 1 minute is enough data to code and erase the partition table on the disk.
  • cat/etc/random >/dev/disk0
  • cat/etc/random >/dev/disk1
  • . C install a new copy of Mac OS x for the hard drive HDD and tested this disk partition hard recovery work.
  • 1. go on diskutil to create a partition called Macintosh HD HDD hard drive using all the space there.
  • 2 do the same with the mechanical hard drive.
  • 3. follow the usual procedure to boot from the installation of OSX USB and install a new copy of Mac OS x hard disk SSD.
  • 4. This will create the correct priming of the partitions, recovery hard drive partitions and PSX partitions hard disk HDD.
  • 5. once the installation is complete, test if OSX may start successfully, but no need to go through the initial MAC OS x didn't put in place that we're going to waste this and do the installation again later.
  • 6. we must now test if the recovery hard drive partition works.
  • 7. reboot for hard drive recovery (see X - by pressing command and R at the same time during boot right after that you hear sound start and release only a few seconds after you see the apple logo and the progress bar for loading...)
  • 8. it is important to test and make sure that the partition of hard drive recovery.
  • D. recreate the fusion drive
  • 1 since us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3
  . on the screen of the terminal type:
• diskutil list.
• You should find that we have a list of disk group hard physical volume only, no logic here still.
• 4. you will see something similar to the screen below.
• 5. search for the largest partition on the SSD hard drive, which should be close to the maximum size of HDD to the SSD (121 G, for example) and mark the name of the device, this will usually be something like/dev/disk0s2
• 6. search the largest disk partition mechanical forming fusion with the SSD hard drive. This should be close to the maximum size of the mechanical hard drive (for example 3 TB) hard disk and mark the name of the device, this will usually be something like/dev/disk1s2
• 7
. Now let's create the merger in car (group alias logical volume) in the Terminal, type: diskutil cs create nom_lecteur driveIDs
• The number of the driveIDs is unlimited, it may be a number of discs, or a number of disk partitions. Always put the faster discs first, for example for our SSD disk0s2
• For example:
• diskutil cs create fusiondrive disk0s2 disk1s2
• diskutil - the version of disk utility command line.
  cs - This calls for Core Storage, which is necessary for the merger.
  create - creates a basic storage group.
  nom_lecteur - is the name of the drive and how you want that he
• appear in the disk utility (not the Finder - that comes later). You can call it what you like; in our example, we named our Fusion table "Fusion".

driveIDs - Here is the Player IDs of the readers you want as part of your Fusion table, separated by a space. In our example, they are 'disk0' and 'disk1', but it may be different in your configuration.
• It is important that the faster hard drive appears first in the command, which in our case the disk0s2 (a partition in the SSD). In this way, drive fusion will use this disk as primary and the cache. The second disc in the command, in this case disk1s2 (a partition on the HARD disk). The secondary disk (HARD drive) is used to store less frequently used files.  Otherwise, the fusion drive performance will be worse that it is designed for.
• 8. you will see something like below appear on the screen:
• Creation Volume logical storage of kernel
• Move isk0s2 storage of carrots
• Disk1s2 of switching for the storage of carrots
• Waiting for logical volume group appear
• Discovered the new group of logical volumes 'DBFEB690-107B-4EA6-905B-2971D10F5B53 '.
• Store LVG UUID: DBFEB690-107B-4EA6-905B-2971D10F5B53
• Finished CoreStorage operation
• 9 copy to the bottom of the string after "Discovering new Volume Logic Group" using the command + C
• 10. next, create the partition of the merger (alias logical volume) drive named "Macintosh HD".
• In the Terminal, type: diskutil createVolume groupString jhfs cs + size volumeName
• For example:
• Diskutil createVolume DBFEB690-107B-4EA6-905B-2971D10F5B53 jhfs cs + 'Macintosh HD' 100%
• diskutil - once again, this is the version of disk utility command line.
• cs - called the basic storage functions, which are necessary for this arrangement.
• createVolume - this is the command to create the storage area real for the reader who is represented by an icon on your desktop.
• groupstring - this is the long alphanumeric string you copied in the previous step. It identifies the table you created such as getting a volume placed on it.
• jhfs + -the format of the disc. It is Apple (journaled) extended Format, which is recommended for drives with an operating system installed on it.
• VolumeName - the actual name of the volume, how it should appear under the icon. If there is a space in the name, you must put the full name in quotes ("name") or put a slash before the (name Drive\) space. In our example, we made these, naming our volume "Macintosh HD".
• size : this is the size of the volume. In our example, we had a 1.1 TB drive. We used '1100g' to describe what 1100 GB (1.1 TB to base 10). Otherwise, we could have also used 1.1 T or even 100% as a size.
• 11. go to diskutil to verify that you can see this new partition on the list.
• 12. test by erasing all the data from it.
• 13. then you can go ahead to start on the USB drive to install OSX and install a new copy of Mac OS x on it.
• 14. This will allow you to keep the recovery disk feature.
• X. how Prime to recover partition
• Press and hold the command and button R set immediately after hearing the bells to boot.
• Only release it 2 seconds after you see the Apple logo on the screen and the progress bar for the start. This will start the partition of hard drive recovery.
• Y. how-to boot OSX install USB
• Press and hold the command and the optionkey together immediately after hearing the ringing of boot.
• Only release it 2 seconds after you see the Apple logo on the screen and it will give you a list of startup disk choice, choose the OSX install USB to boot from.

• Chrome and Safari does not connect

  For some reason when I go to chrome it will not load certain websites. Sites that I used to go in a field such as Facebook, YouTube, twitter, Wikipedia etc work but if I tried to go through a google search for images to putlocker or bbc news, for example, then it doesn't let me, and in the lower left of the screen, it just says connection. After a few minutes, he then said the site could not be reached.

  Custom Safari does not load these pages either.

  Ive ran McAfee for a full scan twice now and it has not detected a virus or threat.

  Ive also uninstalled and reinstalled chrome, but it did nothing.

  No one knows what happened or how to fix it?

  Thank you

  additional information only if you need:

  MacBook pro (retina, mid-2015)

  the processor is Intel core i7 to 2.2 ghz

  and it's OS X Yosemite bersion 10.10.5

  A

  Please uninstall the McAfee product in accordance with these instructions.

  Note that if you have already tried to uninstall the software, you may need to reinstall in order to finish the job. If you have a different version of the product, the steps may be different.

  Back up all data before making any changes. Never install any product "anti-virus" or "anti-malware" again.

  B

  You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

  Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

  VSearch malware tries to hide by varying names of the files it installs. To remove it, you must first identify the naming model.

  1 triple - click on the line below on this page to select, then copy the text to the Clipboard by pressing Control-C key combination:

  /Library/LaunchDaemons

  In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

  There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. The files that belong to an instance of VSearch will have the same date of change within about a minute, so they will be grouped together when you sort the folder this way, which makes them easy to identify.

  Search in the folder with the name of all these forms:

  com.something.daemon.plist

  com.something.Helper.plist

  com.something .net - preferences.plist

  Here, something is a string, which may be different in each instance of VSearch random meaningless. So far it has always been an alphanumeric string without punctuation signs, such as "disbalance" or "thunderbearer."

  You may have more than one copy of the malware, with different values of something.

  There may be one or more files with the name of this form:

  com.somethingelseUpd.plist

  where George can be an empty string of sense that something different. Yet once, there may be more than one file of this type, with different values of Gisele.

  Here is a typical example of an infection VSearch:

  com.disbalance .net - preferences.plist

  com.thunderbearerUpd.plist

  You will have files with similar names, but probably not identical to these.

  If you feel confident that you have identified the files above, drag only the files - nothing - to the trash. You may be prompted for administrator login password. Close the Finder window.

  2. open this folder as in step 1:

  /Library/LaunchAgents

  Move to the trash all the files with the name of the form

  com.something.agent.plist

  where something is one of the strings that you found in step 1. There may be not all of these files.

  3. If you have whatever it is moved to the trash in step 1 and step 2, restart the computer and empty the trash.

  You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

  Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

  Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

  VSearch malware tries to hide by varying names of the files it installs. To remove it, you must first identify the naming model.

  1 triple - click on the line below on this page to select, then copy the text to the Clipboard by pressing Control-C key combination:

  /Library/LaunchDaemons

  In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

  There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. The files that belong to an instance of VSearch will have the same date of change within about a minute, so they will be grouped together when you sort the folder this way, which makes them easy to identify.

  Search in the folder with the name of all these forms:

  com.something.daemon.plist

  com.something.Helper.plist

  com.something .net - preferences.plist

  Here, something is a string, which may be different in each instance of VSearch random meaningless. So far it has always been an alphanumeric string without punctuation signs, such as "disbalance" or "thunderbearer."

  You may have more than one copy of the malware, with different values of something.

  There may be one or more files with the name of this form:

  com.somethingelseUpd.plist

  where George can be an empty string of sense that something different. Yet once, there may be more than one file of this type, with different values of Gisele.

  Here is a typical example of an infection VSearch:

  com.disbalance .net - preferences.plist

  com.thunderbearerUpd.plist

  You will have files with similar names, but probably not identical to these.

  If you feel confident that you have identified the files above, drag only the files - nothing - to the trash. You may be prompted for administrator login password. Close the Finder window.

  2. open this folder as in step 1:

  /Library/LaunchAgents

  Move to the trash all the files with the name of the form

  com.something.agent.plist

  where something is one of the strings that you found in step 1. There may be not all of these files.

  3. If you have whatever it is moved to the trash in step 1 and step 2, restart the computer and empty the trash.

• ERR connection refused for Chrome, Safari, Firefox (most Web sites)

  Hi all

  I am facing a serious problem of internet browser. Yesterday, I suddenly found a Web site connection problem with my MACBook Pro. Specifically, with all browsers such as Chrome, Safari and Firefox, I can't access most websites except Gmail, Youtube, Facebook, etc. All other sites gave an error "Err Connection refused". Surprisingly, I can connect to each Web site with other devices (Ipad, my phone) under this same wifi network... That my MAC did not work properly.

  Then I saw that it had some malware called power helperbar appeared on my site Web whenever I try to re - open my browser. Then, I used all that are available online to get rid of it... Right now, it doesn't seem anymore, but I still can't access most Web sites...

  I checked (I also changed to google DNS 8.8.8.8) DNS, IP, etc, and everything seems normal... At the end of the day, I reinstalled my Macbook system but the problem persists... I have really no more that I can do to fix personally.

  I ask the help of the community?

  Thank you very much

  Best regards

• Error: unable to connect to the server 'Err_connection_refused '.

  Dear friends!

  I use a macbook pro (mid-2012 model year) updated with OS X 10.11.4.

  Recently, I am unable to connect to most of the Web sites in nearly all browsers (firefox, google chrome, safari). I am able to open gmail, sites of apple and google start page.

  Error message in chrome like "Err_connection_refused".

  Error in Safari, as "Safari can't connect to the server.

  I tried to delete the browser cache, cookies and even re-installed browsers. But it helps did ' t.

  I tried to delete the WiFi under preferences and recreated. Still problem persists.

  I am able to display all Web sites in my windows laptop and mobile phones connected to the same WiFi at home.

  Above the problem came recently for 1 week. Please suggest a solution.

  Kind regards
