New log files not 100% usage

I just recently made my web app with new features to require my BDB to have at least 65% use of disk (from the default of 50%) and use of file minimum of 25% (an increase of 5% by default). At the start of my application, I temporarily coded an env.cleanLog () to force a cleanup of the logs to bring the DB up to these parameters to use.

I have deployed the application and its been blowing away the clean process now for about 2.5 hours. It generates a new log file of 100 MB each minute he tries to compact the DB. However, at 2:30, I just ran DbSpace and the use of DB is only up to 51%. Perhaps more surprising are the two following facts:
(1) newspapers newly created vacuuming files are nowhere near 100% use
(2) some newly created log files have already been cleaned (deleted) themselves.

There are 0 updates which passes to the BDB while this process is running. My understanding is that when the cleaner removed the old files and created new files, only good/valid data are written on new files. However, this is not the case. Can someone enlighten me? I am pleased to read the docs if someone can point me in the right direction.

Thank you.

The vacuum cleaner stops turning after the cleaning of several files that are in the environment, because it shows he does not progress. He wakes up again to do clean-up as more data is written by the app. If you call cleanLog, of course, he will do more cleaning.

The FAQ contains a section of performance that you may have missed. The use of the DbCacheSize is there.
http://www.Oracle.com/technetwork/database/BerkeleyDB/je-FAQ-096044.html#34

In general, you need size your cache to your own performance tests. DbCacheSize gives you a guideline. Not enough memory to hold the internal nodes is strongly recommended to achieve a good performance, but your own analysis - including with cleaning of the newspaper - is the last word.

  • imageFORMULA CR-180 check the log file to scan

    Hello

    I work with an imageFORMULA CR-180 check Scanner and when executing a good amount (longer than 100) of the controls, I noticed that the scan control stops and a pop-up window appears on the Analysis ToolPak asked if I would like to replace my log file and start over.

    The software that I use is called "Utility scan for CR-180II" and the log file contains the information of MICR line controls scanned, as well as the date of the analysis, and the location of the file to the images captured from the parser.

    Log file options under "Options-> MICR data parameters.

    What I do, it is by clicking on ' no, I want to overwirte the file ", stop the scan, moving the log of the 'old' file, restart the scanning and backup to a new log file.

    Is there anyway to work around this problem and record continuously in the same log file?

    Is there a memory limit on the scanner?

    Hello

    I don't know if I understand what you want to achieve. If by just seeing the results in the paper mean you saw that puts the output of the order, you can use another file to write the output (I wouldn't leave out the OMBLOG file, it can be handy when you are trying to debug an error). You can use this piece of code:

    Set p_logfile "C:\\my directory\\my file.log.

    Set v_usefile [open "$p_logfile" +]

    puts $v_usefile 'your message '.

    close $v_usefile

    I like to use double quotas in case the file has spaces in its path or name, if there is no space, quotas are not necessary. You can bring order to open at the beginning of your script and the file close to the end, although if your script fails, you will need a new log file, because the one you were using will get blocked until you restart your computer. For complex scripts, I have a procedure that I give the word to write my messages in a file that I keep in a global variable, this procedure opens the file, write the message, and then closes the file. Once get you it working, you don't get the locked log file because the script that you run fails.

  • The log files can be removed automatically in the environment of the HA

    Hi experts BDB.

    I write db HA 4.6.21 the bdb version-based application. Two processes are running on two machines, a master who will be read/write db, one as a client/backup reads only the db. There is a thread in demon master who perform checkpoint all the 1 second: dbenv-> txn_checkpoint (dbenv, 1, 1, 0), and dbenv-> log_archive (dbenv, NULL, DB_ARCH_REMOVE) will be called after runnng checkpoint each time. The env has been opened with indicator: DB_CREATE | DB_INIT_TXN |  DB_INIT_LOCK | DB_INIT_LOG | DB_REGISTER | DB_RECOVER | DB_INIT_MPOOL | DB_THREAD | DB_INIT_REP;   Autoremove indicator has been defined: envp-> set_flags (uid_dbs.envp, DB_LOG_AUTOREMOVE, 1) before open env.

    There is a thread in demon master who perform checkpoint all the 1 second: dbenv-> txn_checkpoint (dbenv, 1, 1, 0), and dbenv-> log_archive (dbenv, NULL, DB_ARCH_REMOVE) will be called after runnng checkpoint each time. The env has been opened with indicator: DB_CREATE | DB_INIT_TXN |  DB_INIT_LOCK | DB_INIT_LOG | DB_REGISTER | DB_RECOVER | DB_INIT_MPOOL | DB_THREAD | DB_INIT_REP;   Autoremove indicator has been defined: envp-> set_flags (uid_dbs.envp, DB_LOG_AUTOREMOVE, 1) before open env.

    I do not say that this is causing a problem, but make the DB_ENV-> log_archive (DB_ARCH_REMOVE) in your thread and setting DB_ENV-> set_flags (DB_LOG_AUTOREMOVE) are redundant. In your thread, you control the timing. The DB_ENV-> set_flags (DB_LOG_AUTOREMOVE) option checks and removes unnecessary log files when we create a new log file.

    Have you seen in the documentation of DB_ENV-> set_flags (DB_LOG_AUTOREMOVE) we do not recommend do deleting files of automatic newspaper with replication? While this warning is not repeated in DB_ENV-> log_archive (DB_ARCH_REMOVE), it also applies to this option. You should review the use of this option, especially if it is possible that your customer could go down for a long time.

    But it is a warning and automatic log removal should work. My first thought here is to ask if your client has recently experienced a synchronization? Internally, we block archive on the client during certain parts of a synchronization master to improve the chances that we will keep all records required by the sync client. We block archiving for 30 seconds after the client synchronization.

    I found this thread https://forums.oracle.com/message/10945602#10945602 that discussed non-ha environment and I tested my code in an env without DB_INIT_REP non-ha, it worked. However in HA env these log files were never deleted.

    This thread is to discuss a different issue. The reason for our BDB 4.6 warning against the use of automatic elimination of log with replication is that it only takes into account all sites in your replication group, so that we can remove a log of the master who always needs a client.

    We added remove auto journal group that supports replication manager replication 5.3 BDB, and this discussion is about a change in the behavior of this addition. With this addition, we no longer need to recommend against the use of elimination automatic log with replication in BDB 5.3 and later versions.

    Could help you in this matter? The customer needs to run checkpoint? Can it be a bug in the bdb?

    I'm not sure that the customer needs to run its own control points, because it performs checkpoints when it receives control point of the master journal records.

    But none of these options to delete log on the master does nothing to remove the logs on the client. You will need to do the following: to archive logs separately to the customer and the master.

  • 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!

  • Size of the log file Archive

    Redlogfile size is 16 MB and generating the archivelog file size is approximately 10 Mb. what could be the reason?

    Oracle Version: 10.2.0.4

    OS: Windows

    Published by: Deccan charger 19 April 2010 23:31

    First of all:

    a redo log contains a lot of things necessary for instance etc. recovery an archived log is used only for the restorations - he didn't need all the stuff that is in a redo log, so when written CRA the archiving log that he does not write all knowledge, all that is required for restores

    Second:

    Archive logs is created with dimensions smaller, irregular, as the original redo logs. Why? [388627.1 ID]

    This document is available to you through process of rapid visibility (RaV) of the Oracle's Support and therefore was not subject to an independent technical review.

    Applies to:
    Oracle Server - Enterprise Edition - Version: 8.1.7.4 to 11.1
    Information in this document applies to any platform.

    Goal
    Archive logs is created with dimensions smaller, irregular, as the original redo logs.
    Commands like:
    ALTER SYSTEM SWITCH LOGFILE
    or
    ALTER SYSTEM ARCHIVE LOG...
    are not used to generate archives or change the log file. Thus, there is no parameter ARCHIVE_LAG_TARGET set.
    What else could cause this behaviour?
    Solution
    From:
    Bug: 5450861: NEWSPAPERS ARCHIVE IS GENERATED with one SIZE SMALLER THAN THE REDO LOG FILES
    the explanation of this situation has 2 main reasons:
    1 archiving logs do not have to be in the same size. This was decided very long ago, when blank padding archiving logs stopped for a very good reason - in order to save disk space.

    2. the log command does not exist when a redo log file is 100% full. There is an internal algorithm that determines when to switch journal. It also has a very good reason - do the command of newspaper at the last moment may incur performance problems (for various reasons, outside the scope of this note).
    So, after that newspaper ordering occurs the archivers are only copying the information from the redo log files. As recovery logs are not 100% full after the command to log and archive logs are empty not filled after the copy operation is complete, this results in unequal files smaller than the original of redo log files.
    This is very apparent for very low (less than 10 MB) log files; as a result, produced 2.5 MB archive logs of 5 MB recovery logs are very visible.
    Just note that currently, the default log files are 100 MB in size. If the archives log files would be between 98 and 100 MB person would notice.
    The main concern that one must have for newspapers of archives files is a possible corruption. This can be easily verified by attempting a resumption of testing. When it's ok, the size of the log archive uneven should be of no interest, as is expected.

    I bought the DVD of 8 Pro Windows by an Australian retailer.

    Win XP is on a 39 GB partition with other application files. I had to delete several files to get the free space necessary to WIN 8 and finally finished by formatting the partition and passes for a COMPLETE new installation.

    Hello

    I solved the problem. It seems that you can not install on a secondary partition with in an earlier version of windows. You must restart the computer and run the installation from a dvd or other media.  Once you get the installation running you should be able to install on another partition without any problems.

    Nice day

  • 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.
