External table log and bad files

Hi, i have defined the following access parameters for my external table and set REJECT LIMIT to 0:
ACCESS PARAMETERS
RECORDS DELIMITED by NEWLINE
BADFILE BAD_DIR:'CARDS.bad'
LOGFILE LOG_DIR:'CARDS.log'
NODISCARDFILE
FIELDS TERMINATED BY ","
OPTIONALLY ENCLOSED BY '"'
READSIZE 1048576
LRTRIM
MISSING FIELD VALUES ARE NULL
REJECT ROWS WITH ALL NULL FIELDS
I want to know everytime i query the external table, my log file and bad file will be overwritten or appended? i want them to be overwritten.

Hi,
Yeah, well, be in for a surprise here:
"The external tables feature is a complement to existing SQL*Loader functionality."

Have you actually read/tried anything?
You can download an XE DB for free and play with that.

  • How to overwrite a log and bad file in external table in oracle 10g

    Hi,
    I have used external table in oracle 10g.whenever use select query in external table orace internally create one log file in specified directory,
    but this log file is growing.How can i overwrite the log file(old to replace with new).I need overwrite a log and bad file in external table.
    kindly give the solutions.
    By
    Siva

    I don't believe that is possible with the LOGFILE clause, but it may be with the BADFILE clause. Here is an excerpt from the documentation :
    The LOGFILE clause names the file that contains messages generated by the external tables utility while it was accessing data in the datafile. If a log file already exists by the same name, the access driver reopens that log file and appends new log information to the end. This is different from bad files and discard files, which overwrite any existing file. NOLOGFILE is used to prevent creation of a log file.
    If you specify LOGFILE, you must specify a filename or you will receive an error.
    If neither LOGFILE nor NOLOGFILE is specified, the default is to create a log file. The name of the file will be the table name followed by _%p and it will have an extension of .log.

  • External portal capturing internal portal URL in Log and trace file

    Hi,
    We are facing one issue in portal like we have two portals for internal (Intranet) and external (Internet) users.
    Once users logged in the application and try to get the information about mylink from the external portal link (internet) they should not get any information about the internal portal.
    But in log and trace file we can see the external portal link capturing the internal portal URL.
    We need to find, from where system capturing the internal portal URL.
    Thanks.

    The tkproffed trace file is in seconds.
    "set timing" is in hh:mi:ss.uu format. So 00:00:01.01 is 1.01 seconds.
    You have to remember that most of these measurements are rounded. While your trace file says it contains one second of trace data, you know it's more.
    One excellent resource for trace files is "Optimizing Oracle Performance" by Cary Millsap & Jeff Holt. (http://www.amazon.com/Optimizing-Oracle-Performance-Cary-Millsap/dp/059600527X ) I thought I knew trace files before, but this book brings your knowledge to a whole new level.
    There is also an excellent WP by Cary Millsap ( http://method-r.com/downloads/doc_details/10-for-developers-making-friends-with-the-oracle-database-cary-millsap ) that gives you some insight.

  • How to get Log and Output File Names for a concurrent request

    Hi,
    I am submitting a concurrent frm OAF with the following code in AM
    try{
    OADBTransaction tx = getOADBTransaction();
    Connection conn = tx.getJdbcConnection();
    ConcurrentRequest cr = new ConcurrentRequest(conn);

    tx.commit();
    }catch(RequestSubmissionException e)
    How do i get the handle to log and output files for the abvoe concurrent request ?
    One more thing is there a way where we can evaluate the environment variables
    like in the above example once i get a the request id
    logfile = $APPLCSF/$APPLOUT/"l"+requestID+".log"
    and
    outputfile=$APPLCSF/$APPLOUT/"o"+requestID+".out"
    is there a way i can get the values of $APPLCSF and $APPLOUT from the os ?
    Thanks
    Tom...
    Thanks
    Tom ...

    You can query the Fnd_Concurrent_Requests table using Request_ID, which has the log & out file directory details.

  • External Hard drive and dmg files not mounting

    External Hard drive and dmg files suddenly not mounting. Im running Mavericks on 27" iMac. Anyone have a fix or has anyone else suddenly had this problem? There was a Mavericks update a few weeks ago, but things were fine until today. This is weird. Ive checked in disk utility and can see one of my two external HD's, the one that I back up. But not even this will mount. Ive tried repairing HD thinking it was damaged but now see that all my ext hd's suddenly dont mount. Ive tried several mac restarts.

    Solved the problem. My external HD is a WD (My Book Studio). I needed to install updated driver manager and this fixed it:

  • Timestamp in Java log and trace files.

    Hi SAP'ies
    Running PI 7.11 on AIX 6.3 we face an issue with the content of log and trace files from Java.
    Eg.
    The file DefaultTrace_00.0.trc is timestamped 18-05-10 11:16:15. (The same time as the time of the OS/AIX)
    Looking inside the file the last statement is timestamped 2010 05 18 09:16:15.
    How can we ensure that the content of these Java files are timestamped with OS time?
    Looking into ABAP files like dev_w0 the timestamp of the file and the content are equal.
    Best regards,
    Teddy Løv Andersen

    Hello All
    Best way to convert the default trace time is , visit the site
    http://www.csgnetwork.com/epochtime.html
    here enter , for example if you have the following in default trace
    #1.#00265510DE7300120000000F000022030004C77AD7309DF5#1345230317066#com.sap.portal.fpn.rdl
    1345230317066   is time stamp , enter this in the above site to get the time

  • Block size in tt for writing data to transaction log and checkpoint files

    Hello,
    what block size is TimesTen using when its writing data to transaction log and checkpoint files? Does it use some fixed block size during filesystem writes?

    Although in theory logging can write 2 KB blocks in almost all circumstances it will write 4 KB or larger so yes a filesystem with a 4 KB block size is fine for both checkpointing and logging.

  • Useful logs and trace files

    Hello experts, for our Netweaver AS administration, I am in charge of periodically checking logs and trace files. I would like to know which are the most useful logs and trace files and the information each one will hold. I am familiar with "DefaultTrace.trc", and as of today it is the only one I have used, but I believe I should also be looking at other logs and trace files.
    Any suggestions?

    Hi Pedro,
    If you are talking about JAVA only system defaulttrace is the best log/trace to look, there are other log files like application log, but maybe the best way to check you logs is using NWA (NetWeaver Administrator) on the following URL on your JAVA system:
    http://<hostname>:<port>/nwa
    From there you need to go to Monitoring -> Logs and Traces and then Predefined View/SAP logs.
    My other recommendation is to change the severity level to ERROR for all you JAVA component within the Visual Administrator -> ServeNode -> Services -> Log Configurator -> Locations, otherwise it is possible that you see a lot of garbage on the defaulttraces. Anyway you can change the severity level per component, on demand, to investigate any possible problem.
    The work directory is very imporant and maybe you can also check the file "dev_serverX" that also will give you information about any out of memory conditions and garbage collection activity if you have these values set for the server node using the config tool:
    -verbose:gc
    -XX:+PrintGCDetails
    -XX:+PrintGCTimeStamps
    You can find more information on here:
    http://help.sap.com/saphelp_nw70/helpdata/en/ac/e9d8a51c732e42bd0e7de54b9ff4e2/content.htm
    Hopefully this help you, let me know if you need more information,

  • Win 2008  WL 10.3.3 stdout appearing in .log and .out files

    Recently noticed a ballooning [ServerName].out file in the logs directory. In weblogic management console I do have it configured to redirect stdout and stderr to weblogic logging (.log file). Both the .log and .out file contain the same stdout/stderr information. I would like to eliminate the .out file if possible (since WL only rotates the .log), but cannot find where it is configured. The managed servers are NOT windows services (no -log option).
    Did not find any logging parameters in JAVA_OPTIONS or paramters in the startManagedSvc.cmd file.
    Is this something needing to be corrected at the application level? (log4j)

  • Basic question on log and temp files

    Hi,
    I need to create a new database in this way:
    - 2 GB for the data file
    - 1 GB for log and temp files
    This is the command I'm issuing to create the db:
    create tablespace xyz datafile '<path>\xyz.dbf' size 2000M reuse;
    How can I say the size of log and temp files?
    Thank you
    Nicola
    Ps-I'm on windows platform

    This is the command I'm issuing to create the db:
    create tablespace xyz datafile '<path>\xyz.dbf' size 2000M reuse;This command does not actually create a database, but a tablespace. If you ran it, that means your db aleady exists.
    So, not sure to follow you on this thread.

    Hi,
    You can control what messages gets logged depending on the severity.
    This can be configured using Log Configurator, check this how you can set severity to different locations.

  • Issue in External Table Authentication and Authorization in OBIEE11G

    Hello Gurus,
    Can anyone help me how to configure External Table Authentication and Authorization in OBIEE11g through weblogic server not like in 10g style(Through INIT Blocks).
    I've followed the (Doc ID 1338007.1) document. But when i'm restart the Managed servers and Admin servers after configuring the SQLAuthenticator all my services are showing down.
    I already raised the SR (SR 3-6286054151) on this issue. But still i didn't get any reply from them.
    Can anyone help me out on this issue or can anyone me send the document for "how to configure External Table Authentication and Authorization in OBIEE11g" . It's really appreciate for your quick response.

    Hi John,
    Thanks for your quick response.
    We configured "ReadOnlySQL Provider" by following the Oracle's white paper(Doc ID 1338007.1) Please find the below steps what we configured in weblogic console.
    1. Created the Data Source
    2. In the data source specified the Database driver--> *Oracle's Driver Thin for service connections: Versions:9.0.1 and later.
    3. Defined the connection Properties .
    4. Selected targets as Admin server and bi_server.
    Then Activate changes
    5. Created new provider by using ReadOnlySQL Authenticator
    6. In the provider specific tab we given the SQL statements and saved it.
    7. Restarted the Admin and Managed servers.
    After restarted the services when we open the Enterprise Manager page all the services are showed as Undefined - means red.
    Apart from that we followed your suggested link http://askjohnobiee.blogspot.com/2012/09/how-to-oid-authentication-with-groups.html
    For External table authentication do we need to configure BISQLAuthenticator or ReadOnlySQLAuthenticator ?
    If we configure BISQLAuthenticator we just import Groups from database to Console application. Then how can it Authenticated to the User ?
    Please let me know your ideas on this.
    Thanks,
    Syam

  • Server.log and access file previous record are overwrite

    Hi,
    I am having problem that my server.log and access file in all instance have been overwrite by latest record. Suppose all the system.out.print will append to the server.log. However, my problem is the log which has been written to server.log in earlier time (mayb morning till afternoon) is replaced. From the server.log, I am only able to view the log which start from 11 pm. The same case happen to access file as well. This incident is not happen everyday but sometimes.
    I am wondering what is happen and how i can solve the problem.
    Any help/guidance is highly appreaciate.

  • Multiplexing redo logs and control files to a separate diskgroup

    General question this one...
    I've been using ASM for a few years now and have always installed a new system with 3 diskgroups
    +DATA - for datafiles, control files, redo logs
    +FRA - for achive logs, flash recovery. RMAN backup
    Those I guess are the standards, but I've always created an extra (very small) diskgroup, called +ONLINE where I keep multiplexed copies of the redo logs and control files.
    My reasoning behind this is that if there are any issues with the +DATA diskgroup, the redo logs and control files can still be accessed.
    In the olden days (all those 5 years ago!), on local storage, this was important, but is it still important now? With all the striping and mirroring going on (both at ASM and RAID level), am I just being overtly paranoid? Does this additional +ONLINE diskgroup actually hamper performance? (with dual write overheads that are not necessary)
    Thoughts?

    Some of the decision will probably depend on your specific environment's data activity, volume, and throughput.
    Something to remember is that redo logs are sequential write, which benefit from a lower RAID overhead (RAID-10, 2 writes per IOP vs RAID-5, 4 writes per IOP). RAID-10 is often not cost-effective for the data portion of a database. If your database is OLTP with a high volume of random reads/writes, you're potentially hurting redo throughput by creating contention on the disks sharing data and redo. Again, that depends entirely on what you're seeing in terms of wait events. A low volume database would probably not experience any noticeable degraded performance.
    In my environment, I have RAID-5 and RAID-10 available, and since the RAID-10 requirement from a capacity perspective for redo is very low, it makes sense to create 2 diskgroups for online redo, separate from DATA, and separate from each other. This way, we don't need to be concerned with DATA transactions impacting REDO performance, and vice versa, and we still maintain redo redundancy.
    In my opinion, you can't be too paranoid. :)
    Good luck!
