• Very large log file C:\ running out of space

  Hi all

  We're going to have a problem with our VCenter server runs low on resources. The hard drive is partitioned in C: and D: drive. The C: folder had only 5 MB of free space on it.

  We did some surveys looked at the SQL logs, which were very small, but in the directory where the databases are stored, we saw a single file in there called ' ESX - Vmotion_Log.LDF' which is 75 GB in size.

  Does anyone know it's important or if it is safe to delete it to free up space on our C:\ drive?

  Thank you

  HM, thatts certainly a Log in SQL Server. Is there a database using this name in your SQL?

  Kind regards

• Analysis & analyze Log files

  Afternoon,

  Yet once thank you advance for looking over my post.

  Here's what I'm working on this period. I'm working on a screen of messaging that is managed via a scheduled task on the hour, every hour. It is of course in coldfusion.

  What I have to do is enter e-mails. The only mention of the status of the e-mail message is in a daily log in the e-mail server. The log file can be between 20 KB to 120 MB. The format of the logfile itself is a little random based on what stage of the E-mail process is on.

  The name of the file is saved as sysMMDD.txt and we have a process that runs every 20 minutes to check the size of the log file for the current date. If it is greater than 10 MB we rename it sysMMDD_1.txt it's really irrelevant to my question but I would like to provide all the information of the thought.

  Going back to the actual format of the journal format it looks like this:

  HH: mm SS:MS TYPE (HASH) [IP ADDRESS] etc.

  Type = type of e-mail or service called

  Hash = a code of unique hash of the email to connect steps

  etc is all the text after the [IP ADDRESS] has no database based on what stage structure.

  The monitor needs to catch all send them in this newspaper between one hour file. Don't forget, the newspaper could contain up to a days worth of data. As it is now I am able to do a count of sending it by searching for the number of times "ldeliver" appears in the log.

  Anyone have any suggestions for the analysis of a log like this? I fear that the way I do it now, which is a hack, is not enough and there is probably a better way to do it.

  Basically, right now I am a cfloop with the index = 'line' through the file. You can imagine how it works with large log files, that's why we created the above scheduled task to rename the log files. Now if I start adding extractions of time as well, I'm sure that this process is going to bust.

  I know that this post is dispersed, but it's just one of those days where everything seems to happen at the same time. Someone at - it other ideas to go about this process? Someone said that an ODBC data source in the text file, but will only work when it is delimited by spaces and only the first "four" pieces are reliable format?

  Any help is appreciated!

  Sorry, Yes.  I don't see you mention that another application generates the log.

  Looping through the file line-by-line adds not really too much of an overload of the resource.  It does not need to load the entire file into RAM, it reads each line in turn.  I tried looping through a file of 1 GB on an instance of CF with only 512 MB of RAM allocated to her and she brassèrent away quite a few lines per millisecond, treatment and that he never broke a sweat.  It took about 7 minutes to treat 1 million lines and never consumed more than a marginal amount of memory.

  Do really know in this way will you gyp?  It doesn't look like the kind of process that must be lightning fast: it is a process in the background, is it not?

  I suppose if you were involved in this topic, you could file through grep the pump at the level of the filesystem first to extract the lines you want and treat this much smaller file.  The file system must process the files of this size quite quickly and effectively.

  I don't would not bother to try to put this stuff in a DB and then treat it: it would be probably more work than just a loop on the file that you are now.

• SQL Loader / WHAT clause / off swich? / bloated log files

  Hello everyone,
  
  I'm loading data using SQL-Loader very large source files. It all works very well.
  
  However, now, by using the WHEN clause (in the control file), I would like to only a very small subset of most load data. This also works very well...
  
  WHEN ARTICLECODE! '000000000000006769' =
  
  However, the log file becomes fully inflated with messages telling me to each record that does not have the WHEN clause...
  
  Record 55078: Discarded - failed all WHEN clauses.
  
  This becomes a problem because it slows down the process and creates large log files that eat upward of my disk space.
  
  There must be a simple command to allow me to disable the messages of thiese, but although I googled on it, I could not find it.
  
  Any ideas on this one? I don't know that it's simple.
  
  Best regards and many thanks,

• synchronization of log file much larger than log file parallel write

  Hi all

  average of log file sync wait is 30 ms log file parallel write is only 10 ms, this mean? What are the main reasons for this difference?

  Hello

  average of log file sync wait is 30 ms log file parallel write is only 10 ms, this mean? What are the main reasons for this difference?

  Essentially, when newspaper writer writes, several session may be waiting. During 10 ms of time, you can have a written lgwr and sessions of 3 user waiting on the 'log file sync '.

• Question about a config/95 G log file: LabView_32_11.0_Lab.Admin_cur.txt

  Hello world

  One of our lab computers running Labview has been reported to be running out of storage and asked me to figure out why. I scratched through some windows folders to find the culprit, specifically folder: c:\users\Lab.Admin\AppData\Local\Temp where I found a 95 G file titled LabView_32_11.0_Lab.Admin_cur.txt, I noticed that the Lab.Admin is the user name and is also included in the name of the file, so I guess it's sort of config/log file for the current user.

  The file was too large for me to open and watch with no matter what program I had available so I just renamed, restarted Labview to check that it might be recreated then removed the bloated file. The newly created file has the following inside the itt:

  ####
  #Date: Wednesday, June 13, 2012 14:49
  #OSName: Windows 7 Professional
  #OSVers: 6.1
  #OSBuild: 7600
  #AppName: LabVIEW
  #Version: 11.0 32-bit
  #AppKind: FDS
  #AppModDate: 22/06/2011 18:12 GMT
  Base address of #LabVIEW: 0x00400000

  Can someone tell me the purpose of this file and what might have caused to grow to 95 G. I'm only interested in learning how to prevent it happening again.

  See you soon,.

  Alex

  Do you mean 95 gigabytes?  95 GB?

  I think that it's a crash dump file in the event where LabVIEW detects an error.  Could you have had a recent accident (perhaps several) where some large scale applications have been involved?

  You can use LabVIEW to open the file.  Write a small VI to open the text file, then just read a smaller number of bytes and display it in an indicator of the chain.

  I have several of these files in my temp directory from to the slightly different versions of LabVIEW installed.  But they are tiny, about 1 KB.

• in the output log file bit 00's are added, why? (Do not run the attached vi. It disables all devices in your system)

  Hi all

  I've attached a zip file when co-existence.vi is the main file of vi that communicates with a USB device and returns some responses of ATR.

  The answers are stored in a log file. I have attached the log file. In the log file in three places while displaying ATR, get added some unwanted 00's. Please help me how it is and how to remove it?

  Thank you

  Mathan

  [Note: (not to run the attached vi.] It disables all devices in your system)].

  It seems that the duration depends on the value you get out of the dll (dwARTLen). You have wired it as 100, so it seems that the dll simply returns the entry. Maybe you want to check the documentation for the dll on the way to get the actual length.

  A large part of your code is very confusing...

  • You have several subVIs that are essentially the same, but with different names. Not one of these not enough?
  • What is the purpose of the loop IN the adhc.vi? Since you autoindex in a table of a line, it will be executed only once, and the result is the same as if you would remove the loop FOR.
  • Your main VI is extremely repetitive with lots of duplicate code. You have 12 instances of the file name constant, would be enough! Enable.VI is identical to disable.vi, except for a constant of diagram. Much the same constant string ("ATR: ', ' peripheral access card:", etc. "), once again, everyone is enough.

  Here a nice state machine would make all the difference.  You need only about 10% of the current code, eliminating all the rehearsals.

• Log files to remove... who?

  A lot, a lot of space occupation of logs with information from many wordy sources... Java, sfc, MSE, third-party scan scan scan, etc. seem to be well hidden in the C: drive.

  These are to be deleted safely? Any general rule to follow when the hard drive for clutters it... for the safe deletion of winnowing? (.. .as in hunting wild mushrooms: edible safely and are edible only once?).

  Hi coolnewyorker,.

  You can safely remove the log files because they are the only files that prevent newspapers of something specific that's happening with the application (an event), the information about it is expressly recorded in a case where a large number of newspapers is kept. Without these files, a user would have been unable to find out what kinds of errors are occurring on their computer on the specific application. This allows the user the ability to diagnose and resolve errors and take the necessary measures and precautions to correct whatever it is.

• SIZE OF THE REDO LOG FILE

  
  Hello

  I got an error message when I add me new group. log files I searched and found the answer on the form. Ago 4 M minimum size of 11 g R2 log file size.

  My question is why a log file size depends on DB_BLOCK_SIZE? This parameter is set to the component structures of memory that create an instance when a log file is an operating system file that depend on the version of the OS not DB_BLOCK_SIZE.

  Thank you.

  SQL > show parameter db_block_size

  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------------------------
  Whole DB_BLOCK_SIZE 8192
  SQL >

  You are assuming that the redo log block size is the same as the database block size. This is not correct.

  The error indicates that 8192 is the minimum number of blocks of a redo log file. The documentation states that the minimum size is 4 M. For example, you can deduct your redo log block size is 512 bytes.

  Here's some more information about the size of redo log, the documentation block.

  Unlike the database block size, which can always be between 2 K and 32 K, redo log default files to a block size that is equal to the size of physical sector of the disk. Historically, it is usually 512 bytes (512 b).

  Some new large disks offer 4K sizes byte (4K) to increase sector efficiency improved format and ECC capabilities. Most of the Oracle database platforms are able to detect this bigger sector size. The database then automatically creates files redo log with a block size of 4 K of these discs.

• trruncate the log file alert

  Hello
  I have an Oracle 10 g installed on Windows 2008 r2. I want to check the alert file to investigate something. But the alert log itself is approximately 1.2 MB, it is very difficult to open with Wordpad and Notepad. If I don't like historical information, can I I just open the alert log file manually delete everything inside and to save it and do this weekly? Or if you have any good suggestion?
  the file that is located at:
  e:\oracle\database\product\10.2.0\admin\orcl\bdump\alert_orcl.log

  Hello

  To do this, since you are on windows, argue some more text editor that can take care of some large files.

  Other than that, if you do not want your alert log that would be huge if you want specific entries in the file, just move the old file or rename it before starting your activity you want to monitor. Database server will create a new file for you and which will logically be truncated for you.

  Thank you

• bottleneck during the passage of the redo log files.

  Hi all
  
  I'm using Oracle 11.2.0.3.
  
  The enforcement team has indicated that they are facing slow at some point.
  
  I followed the database and I found that at some passage of redo log files (not always), I am facing a slow at the application level.
  
  I have 2 son since my database is CARS, each thread has 3 groups of multiplexed redo logs the FIU, with size of 300 MB each.
  
  Is it possible to optimize the switch of the redo log files? knowing that my database is running in ARCHIVELOG mode.
  
  Kind regards

  Hello

  Yes, Oracle recommends 1 validation by 30 calls from users or less. Of course, every database is different, so this rule cannot be taken too literally, but in your case, this rule seems to apply. In any case State, 900 undertakes seconds it looks like a very large number and the need for a high number of transactions should be questioned. You should talk to your analysts/application management/enterprise architect if warranted - that is to say if the application does in fact almost 2 000 business transactions per second.

  What about DB CPU: here is a link to a blog that I wrote on this subject, it should help to better understand this number:

  http://Savvinov.com/2012/04/06/AWR-reports-interpreting-CPU-usage/

  But briefly: DB processor isn't a real event, it is simply an indication that the sessions are on CPU (or waiting for CPU) rather than wait on i/o requests or events in the database. It is not necessarily a bad thing, because the database must perform tasks and he cannot do without loading the CPU. It may indicate a problem in two cases: when the CPU usage is close to the limit of the host (OS stats section indicates that you are very far from there) or when the CPU is a % of DB time - in the latter case, this could mean that you are making too many logical reads due to inefficient plans or analysis too. In any case, this does not apply to you, because 20 percent is not very high a number.

  Other items in the list of the top 5 deserve attention, too - gc buffer busy acquire, gc current block busy, enq: TX - line lock conflict.

  To summarize, your database under a lot of stress - whether it is the legitimate workload, and if this is the case, you may need to upgrade your hardware later. There is chance that it isn't - for example a high number of runs may indicate that rather than to bulk operations database code using PL/SQL loops, which is a big performance killer. Check "Top SQL by executions" about whether or not this is the case.

  Good luck!

• Removal of log files

  I'm running out of space on my folder/var/log. After having many problems with a cluster yesterday, I have a large number of log files in this folder. Any thoughts on which those can be deleted?

  My understanding is that any numbered log file could be removed safely (that is to say, vmkernel.33, or pass - 7.log.)  Here are some of the multiple log files I have. Suggestions are appreciated!

  In ' / var/log ', the following people have the file name, plus at least 4 filename.1

  Boot.log; cron; ksyms; e-mail log; messages; rpmpkgs; guarantee; spoole; vmkwarning

  Then I have:

  VMkernel and vmkernel.1 - 36

  In/var/log/vmware I have:

  esxcfg - boot.log 1-4
  hostd.log and 0.log - through the intermediary of pass - 9.log;
  several TGZ files, 'spend - support.tgz 1-4", all have date yesterday on them. Don't know what happened there...
  and a bunch of vmware-cim - 0.log through vmware - cim.9.log

  OK, so you get the idea...

  Hello

  Delete all log file that ends in a number. Those are backups. Also, remember to delete the log files from/var/log/vmware as well.

  The 'logrotate' configuration should be configured to do this automatically for you. Discover all the pointee VMware hardening Guideline by top Virtualizaition safety links ESX/ESXi section. It is a good step to take.

• How can I purge transaction logs files?

  I have a transactional database (i.e., created by using the db. DB_CREATE | DB. DB_INIT_TXN | DB. DB_INIT_LOCK | DB. DB_INIT_LOG | DB. DB_INIT_MPOOL flags) which also generates a file log.0000000001 as part of its operation.
  
  The log file exceeds the limit of 10 MB by default recently, and I saw this error: ' Region of logging out of memory»
  
  While it was easy enough to fix (temporarily) by setting the variable configuration set_lg_regionmax for a larger number, is it possible to purge just the file log.0000000001 to something significantly less than 10 MB?
  
  In my PB, I don't have a history longer than the previous transaction, so no logging more is superfluous.

  Hello

  Yes, by using the DB_LOG_AUTO_REMOVE flag with the log_set_config of the environment
  method automatically deletes log files that are no longer needed. Another suggestion is to take a look at the method of log_archive environment with the DB_ARCH_REMOVE flag, which also removes log files that are no longer needed. It is documented at:

• Folight - SQL Server 2008 R2, DBSS - error log file size

  Hey guys,.

  Try to understand why the alarm DBSS - size of error log is shooting. Why does foglightr not read these log files? Is this a mistake in my setup?

  "The size of the file SQL Server log Archive 6 is 2 685,00 KB, which is too big for the scan. Analysis is disabled.  "

  Hi Daniel,.

  There is a default setting of 1 024 KB for this rule in order to avoid possible performance issues by reading a log file that is too large. You can change the limit by checking the boxes next to the instances of SQL Server in the data base Control Panel and proceed to the Administration of the Agent. Select alarms and then DBSS - size of error log and change the threshold. You can try to 3000 as a value.

  Kind regards
