We used rsync 2.6.3 on a couple of Solaris 8 machines to update an Oracle database from one machine to another. Here is the procedure I used: The source database was up and running so this operation was similar to doing a hot backup. I queried the source database for a list of tablespace names, and for each tablespace, I queried the list of datafiles. I put the tablespace in hot backup mode,

Hi. I am trying to use the linear optimizer from package lpSolve in R 2.4.1 on Windows XP (Version 5.1). The problem I am trying to solve has 2843 variables (2841 integer, 2 continuous) and 8524 constraints, and I have 2 Gb of memory. After I load the input data into R, I have at most 1.5 Gb of memory available. If I start the lp with significantly less memory available (say 1 Gb), I get

Hi Everyone... Hope that everyone is doing fine. We have an ocfs2 installation (linux x86_64, RHEL4 update 5), ocfs2 1.2.5. Oracle 10gR2 Rac 10.2.0.2 2 nodes. When we were testing failures, we unplugged the private interfaces from 1 node. As expected 1 node rebooted. As it was coming up we realized (From the error messages on the console) that ocfs was having

SPSS seems to have changed its default datafile format, resulting in issues for read.spss(). In Windows this results in a warning, in Debian the import completely fails: Debian (R version 2.8.0 (2008-10-20) i486-pc-linux-gnu, foreign_0.8-29) > read.spss("/home/jeroen/samples/Tomato.sav") Error in iconv(names(rval), cp, "") : unsupported conversion from 'CP65001'

Say I want to gather info from various Models... Files, Folders, and put them into a ''display'' Object DisplayFilesystem that will standarize the info from both tables (for display only)...

Hi, We currently use rsync to create an Oracle standby on a target box from an existing standby by copying all the datafiles while the source standby is in recovery status. We are occasionally running into datafile corruptions being reported by oracle when it is recovering the new standby. Oracle support says they don't recommend copying files while the changes being applied to them unless

I have noticed that OCFS is not updating the filesystem space stats when datafiles are reduced in size: is this Bug 62, and if so is there an expected fix date? ocfs-2.4.9-e-enterprise-1.0.11-1 ocfs-support-1.0.10-1 ocfs-tools-1.0.10-1 Linux sgl43d-122 2.4.9-e.35enterprise #1 SMP Wed Jan 7 15:11:27 EST 2004 i686 unknown bytes name 2097152000 /data/oracle/QSG40/u01/dtr_med_i_02.dbf /dev/sdc1

Hello, I was reading your posts about RSYNC. We have a massive Oracle schema lots of datafiles about 750 GB size. We do rsync datafiles from source to target server but everytime we cleanup the datafiles on the target server and do rsync every 2 weeks. On the target side mostly the datafiles will be same but on source we might have added few datafiles or made some changes in data and as such the

Hi folks, I'm prepared building my own datafiles, simple file at start, for testing wondering how to process? Which software will be used, MySQL/MS-SQL/MS-Excel/Open Office-Calc etc? On searching I found r-cran-rmysql on Ubuntu repo. Further searching I found; RMySQL: R interface to the MySQL database http://cran.r-project.org/web/packages/RMySQL/index.html Whether install the above

Hello, I've imported a csv, semi-colon spearated file with read.csv2, containing one column of rownames and one column of floating point numbers. When I look at the column of data with framename$columnname, I get the values of the column plus level values. Are these level values created automatically ? The problem is when I try to calcluate the correlation coefficient between this set of data

R2.13.2, W7x64 Dear list, Excuse my ignorance, but I have gone through the R help (?parse, ?eval, etc.) and still really don't know how to do the following. I have the general following structure that I would like to automate [edited to make it shorter]: >>> city1997 <- dataCleaning(read.csv2("C:\\city\\year1997.txt")) city1997 <- wasteCalculations(city1997, year

Hello, I am fairly new to R programming and am stuck with the following problem. I am trying to read in multiple files (see attached file or at end of email), the files all have the same general header information and different precipitation (avgppt) and area (areasqmi) values. Some times the number of records are different in the files. I want to read in all files (.stdsummary), and create

Dear all, I have a huge problem after downloading and exporting data from Reuters3000 XTra: I downloaded many many monthly, quarterly and yearly data. I do not know why, but after saving, I have mixed-data sets, i.e. files which can be imported as “read.csv” and others that are in the format of “read.csv2”. Sure I could change them, but normally it should be possible to mix them… For

Full_Name: Martin O'Gorman Version: OS: Submission from: (NULL) (84.176.63.149) I have been looking at the PPC package and have a question. As the input data is comma separated, shouldn?t the command to read in the raw (no batch) mass spec data indicate that sep=?,? (marked below) ? Otherwise, the data read in is the pair of values (m/z,intensity). It is not obvious why that should be.

A new version of the ggplot2 web application is available at http://www.yeroon.net/ggplot2. New features include 1D geom?s (histogram,?density, freqpoly), syntax mode (by clicking the tiny arrow at the?bottom), and some additional facet options. Furthermore some minor?improvements and fixes, most notably for Internet Explorer. As usual, a little demo video that shows how to use the new features:

All, I am having trouble with a "read.table()" function that is inside of another function. But if I call the function by itself, it works fine. Moreover, if I run the script on a Mac OS X (with the default Mac OS X version of R installed, rev 2.8), it works fine. But it does not work if I run it on windows vista (also default Windows version of R, rev. 2.8). Again, both
