  • Ruby script/console and Ruby script/server using two different DBs?

    - by aronchick
    Has anyone seen where script/console and script/server load two different databases (though both report using the same)? Here's the first output $ script/server => Booting WEBrick => Rails 2.3.5 application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2010-03-21 15:54:05] INFO WEBrick 1.3.1 [2010-03-21 15:54:05] INFO ruby 1.8.7 (2010-01-10) [i386-mingw32] [2010-03-21 15:54:05] INFO WEBrick::HTTPServer#start: pid=7148 port=3000 No errors. I then run my standard code for entering a form - no problems. Checking the Dev Database (.yml at bottom): mysql> select * from books; [...] | 712 | Book | Book Name | 2010-03-21 22:29:22 | 2010-03-21 22:29:22 | [...] 712 rows in set (0.00 sec) The code CLEARLY saved it seconds ago And now here's the output of script/console: $ script/console Loading development environment (Rails 2.3.5) >> Books.all => [] Nothing. Further, upon further inspection, it's using the production database, but I can't figure out why. Any thoughts here? All consoles have been closed and reopened. UPDATE: Requested .yml file (can't see how it'd be helpful (user name and password are all the same for each)) - development: adapter: mysql database: BooksDBdev username: <user name> password: <long string> timeout: 5000 # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: mysql database: BooksDBtest username: <user name> password: <long string> timeout: 5000 production: adapter: mysql database: BooksDB username: <user name> password: <long string> timeout: 5000

  • help! corrupt file recovery

    - by TheBumpper
    My supervisor computer crashed last night, and I'm trying to help him out. He made an R script but when he tried to open it, it was empty. But for some reason the file is 7.9kb so it should not be empty i think... anyway when i tried to open it, Gedit gave this error: "The file you opened has some invalid characters. If you continue editing this file you could corrupt this document. You can also choose another character encoding and try again." and the options to encode the characters. It looked like this(with a red background): \00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\ My question is, is there a way to restore the file? i hope someone has a brilliant idea

  • Deploying an ADF Secure Application using WLS Console

    - by juan.ruiz
    Last week I worked on a requirement from a customer that wanted to understand how to deploy to WLS an application with ADF Security without using JDeveloper. The main question was, what steps where needed in order to set up Enterprise Roles, Security Policies and Application Credentials. In this entry I will explain the steps taken using JDeveloper 11.1.1.2. 0 Requirements: Instead of building a sample application from scratch, we can use Andrejus 's sample application that contains all the security pieces that we need. Open and migrate the project. Also make sure you adjust the database settings accordingly. Creating the EAR file Review the Security settings of the application by going into the Application -> Secure menu and see that there are two enterprise roles as well as the ADF Policies enforcing security on the main page. Make sure the Application Module uses the Data Source instead of JDBC URL for its connection type, also take note of the data source name - in my case I have: java:comp/env/jdbc/HrDS To facilitate the access to this application once we deploy it. Go to your ViewController project properties select the Java EE Application category and give it a meaningful name to the context root as well to the Application Name Go to the ADFSecurityWL Application properties -> Deployment  and create a new EAR deployment profile. Uncheck the Auto generate and Synchronize weblogic-jdbc.xml Descriptors During Deployment Deploy the application as an EAR file. Deploying the Application to WLS using the WLS Console On the WLS console create a JNDI data source. This is the part that I found more tricky of the hole exercise given that the name should match the AM's data source name, however the naming convention that worked for me was jdbc.HrDS Now, deploy the application manually by selecting deployments ->Install look for the EAR and follow the default steps. If this is the firs time you deploy the application, once the deployment finishes you will be asked to Activate Changes on the domain, these changes contain all the security policies and application roles insertion into the WLS instance. Creating Roles and User Groups for the Application To finish the after-deployment set up, we need to create the groups that are the equivalent of the Enterprise Roles of ADF Security. For our sample we have two Enterprise Roles employeesApplication and managersApplication. After that, we create the application users and assign them into their respective groups. Now we can run the application and test the security constraints

  • Disaster Recovery Plan&ndash;Rebuild System Disk (Dell Server 2900 with PERC RAID controller)

    - by Jim Lahman
    Goal: Since the system disk is a RAID 1 mirrored set, we can rebuild the shadow set by replacing one of the good sets with a blank disk Steps Shutdown and power down server Remove the disk from bay 9, which is part of the system shadow set. Put this disk on the shelf Insert blank/old disk into the empty bay     Label the new disk before inserting it into the empty bay       Power up server During the booting process, the following message appears: “Some configured disks have been removed from your system…”       Press ‘C’ to Load Configuration utility             Press 'Y' to confirm to load the foreign configuration       In this example, the system shadow set is Disk Group 2.  (Before proceeding, confirm this is the disk group in your case).  Expanding the physical disks shows a disk in bay 8 and a missing disk in bay 9.  This is correct.   Now, we have to include the new inserted disk in this group       RAID controller reporting bay 9 is empty       There may be times when the new disk is seen as a foreign disk.  In this case, do the following:     Foreign disk is reported in bay 9 CTRL-N (Next Page) to Foreign Mgt All the disk groups will be displayed.  Typically, the disk group containing the foreign disk will be grey.  To remove the foreign disk Highlight Controller Press F2 Select Foreign Select Clear (do NOT import the configuration!)       Clear the foreign configuration Now the disk can be brought into the system shadow set disk group as a hot spare   To include the newly inserted disk into the system shadowset disk group, it must be brought in as a hot spare Highlight Disk Group 2 (VD Management) Hit F2 Select 'Manage Ded. HS'     Manage dedicated hot swap Select the disk in bay 9 (Hit space bar to select) Tab to 'OK'.  Hit the return key     Select hot spare to bring into RAID 1 mirror set   Rebuild automatically commences     Rebuild in process   Restart now or restart after rebuild is completed

  • Can I use a multi-line function or control flow segment into the PowerShellFar editor console

    - by Justin Dearing
    If I am running farmanager with FarNet and PowerShellFar I can bring up a console of sorts by selecting F11 | .NET PowerShell | Editor Console. This console is based on the far editor. I can paste snippets of powershell scripts into this console and edit them. The only problem is if I want to use a multi-line function or control flow segment in the console. If I paste it in it has no effect. If I attempt to type one in I get an error similar to: ERROR: IncompleteParseException: Missing closing '}' in statement block. At line:1 char:42 + foreach ($number in 1..10 ) { $number * 7 <<<< + CategoryInfo : ParserError: (CloseBraceToken:TokenId) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : MissingEndCurlyBrace Is this simply a limitation of PowerShellFar?

  • Real or False Recovery? Economic 'tea-leaves'

    - by [email protected]
    "Information-technology is allowing the city's economy to speak to us in lots of different ways," Mr. Egan said. "We just need to find new ways of listening." Source: "New Way to Read Economy" WSJ_ARTICLE  April 8th, Carli Tuna, Blog by ARC's Steve Banker Apr 12, 2010 Alan Greenspan used cardboard box purchases and other 'source-commodity' indicators. The Carli Tuna WSJ article said that truck diesel fuel sales are a reliable indicator. What factor do you and your company use as future forward indicators? .. is it quotes, perhaps calls into the call center or sales activity?  Is your business moving to the internet and your supply chain driven by your iStore?  How do your distributors, retailers and supply chain partners provide the 'side-line' signals to you to either ramp up or contract production? With competition being only one click away, organizations need to know with higher degrees of certainty, what the econmic 'tea-leaves' are telling us and how firms need to react with production and shipping forecasts.  Firms using the latest forecasting and supply chain analytical (Bus.Intelligence) tools and technologies appear to be leading their markets "Had we been aware of that data in 2008," Mr. Leamer said, "we would have made a different call." .

  • VMware ESXi - vSphere - Can't exit VM console access

    - by caleban
    I'm running ESXi 4.1 on a Dell T110 Server I connect to ESXi using vSphere vSphere is running inside a Windows 7 VM The Windows 7 VM is running in VMware Fusion on my Mac OS X system When I'm in vSphere and I've selected a VM and I click the console tab on some systems the VM console won't release me when I press the control + command keys. pfSense (FreeBSD) and Ubuntu Server behave like this. I can't exit their console screen. I have to shut down these VM's to be released from their VM console access. Windows, Ubuntu Desktop, etc. all behave like I'd expect; When I press the control + command keys I'm released from the VM console and I'm able to navigate in vSphere. Does anyone know what might be causing this or a way around this? Thanks in advance.

  • Cluster Node Recovery Using Second Node in Solaris Cluster

    - by Onur Bingul
    Assumptions:Node 0a is the cluster node that has crashed and could not boot anymore.Node 0b is the node in cluster and in production with services active.Both nodes have their boot disk mirrored via SDS/SVM.We have many options to clone the boot disk from node 0b:- make a copy via network using the ufsdump command and pipe to ufsrestore - make a copy inserting the disk locally on node 0b and creating the third mirror with SDS- make a copy inserting the disk locally on node 0b using dd commandIn this procedure we are going to use dd command (from my experience this is the best option).Bare in mind that in the examples provided we work on Sun Fire V240 systems which have SCSI internal disks. In the case of Fibre Channel (FC) internal disks you must pay attention to the unique identifier, or World Wide Name (WWN), associated with each FC disk (in this case take a look at infodoc #40133 in order to recreate the device tree correctly).Procedure:On node 0b the boot disk is c1t0d0 (c1t1d0 mirror) and this is the VTOC:* Partition  Tag  Flags    Sector     Count    Sector  Mount Directory      0      2    00          0   2106432   2106431      1      3    01    2106432  74630784  76737215      2      5    00          0 143349312 143349311      4      7    00   76737216  50340672 127077887      5      4    00  127077888  14683968 141761855      6      0    00  141761856   1058304 142820159      7      0    00  142820160    529152 143349311We will insert the new disk on node 0b and it will be seen as c1t2d0.1) On node 0b we make a copy via dd from disk c1t0d0s2 to disk c1t2d0s2# dd if=/dev/rdsk/c1t0d0s2 of=/dev/rdsk/c1t2d0s2 bs=8192kA copy of a 72GB disk will take approximately about 45 minutes.Note: as an alternative to make identical copy of root over network follow Document ID: 47498Title: Sun[TM] Cluster 3.0: How to Rebuild a node with Veritas Volume Manager2) Perform an fsck on disk c1t2d0 data slices:   1.  fsck -o f /dev/rdsk/c1t2d0s0 (root)   2.  fsck -o f /dev/rdsk/c1t2d0s4 (/var)   3.  fsck -o f /dev/rdsk/c1t2d0s5 (/usr)   4.  fsck -o f /dev/rdsk/c1t2d0s6 (/globaldevices)3) Mount the root file system in order to edit following files for changing the node name:# mount /dev/dsk/c1t2d0s0 /mntChange the hostname from 0b to 0a:# cd /mnt/etc# vi hosts # vi hostname.bge0 # vi hostname.bge2 # vi nodename 4) Change the /mnt/etc/vfstab from the actual:/dev/md/dsk/d201        -       -       swap    -       no      -/dev/md/dsk/d200        /dev/md/rdsk/d200       /       ufs     1       no      -/dev/md/dsk/d205        /dev/md/rdsk/d205       /usr    ufs     1       no      logging/dev/md/dsk/d204        /dev/md/rdsk/d204       /var    ufs     1       no      logging#/dev/md/dsk/d206       /dev/md/rdsk/d206       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/md/dsk/d206        /dev/md/rdsk/d206       /global/.devices/node@2 ufs     2       noglobalto this (unencapsulate disk from SDS/SVM):/dev/dsk/c1t0d0s1        -       -       swap    -       no      -/dev/dsk/c1t0d0s0       /dev/rdsk/c1t0d0s0       /       ufs     1       no      -/dev/dsk/c1t0d0s5       /dev/rdsk/c1t0d0s5       /usr    ufs     1       no      logging/dev/dsk/c1t0d0s4       /dev/rdsk/c1t0d0s4       /var    ufs     1       no      logging#/dev/md/dsk/d206       /dev/md/rdsk/d206       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/dsk/c1t0d0s6       /dev/rdsk/c1t0d0s6       /global/.devices/node@1 ufs     2       no globalIt is important that global device partition (slice 6) in the new vfstab will point to the physical partition of the disk (in our case slice 6).Be careful with the name you use for the new disk. In this case we define it as c1t0d0 because we will insert it as target 0 in node 0a.But this could be different based on the configuration you are working on.5) Remove following entry from /mnt/etc/system (part of unencapsulation procedure):rootdev:/pseudo/md@0:0,200,blk6) Correct the link shared -> ../../global/.devices/node@2/dev/md/shared in order to point to the nodeid of node 0a (in our case nodeid 1):# cd /mnt/dev/mdhow it is now.... node 0b has nodeid 2lrwxrwxrwx   1 root     root          42 Mar 10  2005 shared ->../../global/.devices/node@2/dev/md/shared# rm shared# ln -s ../../global/.devices/node@1/dev/md/shared sharedhow is going to be... with nodeid 1 for node 0alrwxrwxrwx   1 root     root          42 Mar 10  2005 shared ->../../global/.devices/node@1/dev/md/shared7) Change nodeid (in our case from 2 to 1):# cd /mnt/etc/cluster# vi nodeid8) Change the file /mnt/etc/path_to_inst in order to reflect the correct nodeid for node 0a:# cd /mnt/etc# vi path_to_instChange entries from node@2 to node@1 with the vi command ":%s/node@2/node@1/g"9) Write the bootblock to the disk... just in case:# /usr/sbin/installboot /usr/platform/sun4u/lib/fs/ufs/bootblk /dev/rdsk/c1t2d0s0Now the disk is ready to be inserted in node 0a in order to bootup the node.10) Bootup node 0a with command "boot -sx"... this is becasue we need to make some changes in ccr files in order to recreate did environment.11) Modify cluster ccr:# cd /etc/cluster/ccr# rm did_instances# rm did_instances.bak# vi directory - remove the did_instances line.# /usr/cluster/lib/sc/ccradm -i /etc/cluster/ccr/directory # grep ccr_gennum /etc/cluster/ccr/directory ccr_gennum -1 # /usr/cluster/lib/sc/ccradm -i /etc/cluster/ccr/infrastructure # grep ccr_gennum /etc/cluster/ccr/infrastructure ccr_gennum -112) Bring the node 0a down again to the ok prompt and then issue the command "boot -r"Now the node will join the cluster and from scstat and metaset command you can verify functionality. Next step is to encapsulate the boot disk in SDS/SVM and create the mirrors.In our case node 0b has metadevice name starting from d200. For this reason on node 0a we need to create metadevice starting from d100. This is just an example, you can have different names.The important thing to remember is that metadevice boot disks have different names on each node.13) Remove metadevice pointing to the boot and mirror disks (inherit from node 0b):# metaclear -r -f d200# metaclear -r -f d201# metaclear -r -f d204# metaclear -r -f d205# metaclear -r -f d206verify from metastat that no metadevices are set for boot and mirror disks.14) Encapsulate the boot disk:# metainit -f d110 1 1 c1t0d0s0# metainit d100 -m d110# metaroot d10015) Reboot node 0a.16) Create all the metadevice for slices remaining on boot disk# metainit -f d111 1 1 c1t0d0s1# metainit d101 -m d111# metainit -f d114 1 1 c1t0d0s4# metainit d104 -m d114# metainit -f d115 1 1 c1t0d0s5# metainit d105 -m d115# metainit -f d116 1 1 c1t0d0s6# metainit d106 -m d11617) Edit the vfstab in order to specifiy metadevices created:old:/dev/dsk/c1t0d0s1        -       -       swap    -       no      -/dev/md/dsk/d100        /dev/md/rdsk/d100       /       ufs     1       no      -/dev/dsk/c1t0d0s5       /dev/rdsk/c1t0d0s5       /usr    ufs     1       no      logging/dev/dsk/c1t0d0s4       /dev/rdsk/c1t0d0s4       /var    ufs     1       no      logging#/dev/md/dsk/d206       /dev/md/rdsk/d206       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/dsk/c1t0d0s6       /dev/rdsk/c1t0d0s6       /global/.devices/node@1 ufs      2       no  globalnew:/dev/md/dsk/d101        -       -       swap    -       no      -/dev/md/dsk/d100        /dev/md/rdsk/d100       /       ufs     1       no      -/dev/md/dsk/d105        /dev/md/rdsk/d105       /usr    ufs     1       no      logging/dev/md/dsk/d104        /dev/md/rdsk/d104       /var    ufs     1       no      logging#/dev/md/dsk/106       /dev/md/rdsk/d106       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/md/dsk/d106        /dev/md/rdsk/d106       /global/.devices/node@1 ufs     2       noglobal18) Reboot node 0a in order to check new SDS/SVM boot configuration.19) Label the mirror disk c1t1d0 with the VTOC of boot disk c1t0d0:# prtvtoc /dev/dsk/c1t0d0s2 > /var/tmp/VTOC_c1t0d0 # fmthard -s /var/tmp/VTOC_c1t0d0 /dev/rdsk/c1t1d0s220) Put DB replica on slice 7 of disk c1t1d0:# metadb -a -c 3 /dev/dsk/c1t1d0s721) Create metadevice for mirror disk c1t1d0 and attach the new mirror side:# metainit d120 1 1 c1t1d0s0# metattach d100 d120# metainit d121 1 1 c1t1d0s1# metattach d101 d121# metainit d124 1 1 c1t1d0s4# metattach d104 d124# metainit d125 1 1 c1t1d0s5# metattach d105 d125# metainit d126 1 1 c1t1d0s6# metattach d106 d126

  • How to switch off wifi on startup or from the console

    - by mit
    I have installed ubuntu 10.04 on a laptop. Wifi is switched on by default on startup. I can disable it rightclicking the network manager icon in the gnome bar. How can I set it to have wifi switched off as default? Alternatively, how can I switch off wifi on the console? I tried already the rfkill command but it does not list any devices and it does not switch off wifi, I tried different parameters. This is a standard install of the Ubuntu 10.04 i386 Desktop Live CD on an IBM T40 Laptop. EDIT A: This is the output of some rfkill commands on my system, and it does not affect the wifi of the laptop: $ rfkill --help Usage: rfkill [options] command Options: --version show version (0.4) Commands: help event list [IDENTIFIER] block IDENTIFIER unblock IDENTIFIER where IDENTIFIER is the index no. of an rfkill switch or one of: <idx> all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm $ rfkill list $ rfkill list wifi $ rfkill list all $ rfkill list wlan $ sudo rfkill list all $ sudo rfkill block all $ sudo rfkill block wlan $ sudo rfkill block wifi $ EDIT B: Now I found out that sudo ifconfig eth1 down turns it off. And I can turn it on through the gnome network applet again. But the applet does not reflect the change from the commandline, it stills believes wifi is switched on. I have to switch it off and on again on the applet to switch it on again, when I switched it off from the console. Is there a better way? This is what the syslog looks like when I switch wireless off and on again from the network manager: NetworkManager: <info> (eth1): device state change: 3 -> 2 (reason 0) NetworkManager: <info> (eth1): deactivating device (reason: 0). NetworkManager: <info> Policy set '24' (eth0) as default for routing and DNS. NetworkManager: <info> (eth1): taking down device. avahi-daemon[660]: Withdrawing address record for fe80::202:8aff:feba:d798 on eth1. kernel: [ 971.472116] airo(eth1): cmd:3 status:7f03 rsp0:0 rsp1:0 rsp2:0 NetworkManager: <info> (eth1): bringing up device.

  • How to wrap console utils in webserver

    - by Alex Brown
    I have a big dataset (100Mbs/day) and a bunch of console a TCL/TK tools to view it - I want to turn it into a web app that I can build, and others can maintain. In long: my group runs simulations yielding 100s of Mbs of data daily, in multiple (mostly but not only) text forms. We have a bunch of scripts and tools, mostly old school 1990's style stuff requiring a 5-button mouse, as well as lots of ad-hoc scripts that engineers build out of frustration every month or so. These produces UIs, graphs, spreadsheets (various sizes), logs, event histories etc. I want to replace (or at least supplement) the xwindows / console style UI with a web-based one, so I need the following properties: pleasant to program can wrap existing command-line tools in separate views (I don't need to scrape GUIs or anything) as I port logic from the existing scripts I can create a modularised and pleasant codebase to replace it I can attach a web-ui to navigate between views - each view is likely to contain keys which might make sense to view in another I am new to building systems that have logic on the back-end and front-end of a web-server. from that point of view, they do this: backend wraps old-school executables, constructs calls into them and them takes the output and wraps it up, niceifies it and delivers it to the web client. For instance the tool might generate a number of indexed images (per invocation) which I might deliver all at once or on-demand. May (probably) need to to heavy stats on some sources. frontend provides navigation connecting multiple views, performs requests from one view for data from another (or self to self), etc. Probably will have some views with a lot of interactivity. Can people please point me towards viable solutions for this? I know it's a bit of an open question so as answers come in I hope to refine the spec until we have a good match. I guess I expect to see answers like "RoR!" "beans!" "Scala!" but please give an indication of why those are a good fit; I know nothing! I got bumped off SO for asking an open-ended question, so sorry if its OT here too (let me know). I take the policy that I use the best/closest matched language for a project but most of my team are extremely low level (ie pipeline stages and CDyn) so I don't have the peer group to know where to start.

  • How to check that I have recovered from Penguin 2.0?

    - by Simon Walker
    I have 3 year old website which has been hit by Penguin 2.0 in May. The website traffic dropped almost 30%. I have been working hard from last 2.5 months on the website and my website's traffic recovered in last week of August. In fact, I am receiving more traffic then ever. When I look at the stats, I find my website's search engine visibility has been improved. It is now appearing for more search queries. My website's impressions have also increased. What I am worried about is that my website is nowhere in top 5 pages for keywords having high competition and carrying the highest search volume. They are few in number but important. Should I consider my current situation as recovery or it's just the partial recovery? If it is only partial, then how come traffic is more then it was before penguin 2.0?

  • Creating a bootable USB recovery drive to be used by someone who isn't computer savvy

    - by David
    I am looking for a way to prepare an image of an Ubuntu machine which would be bootable and installable in the easiest way possible. I'm actually preparing an Ubuntu machine for someone living far, and not computer savvy. If he ever has troubles with his installation, he could just put a USB drive in, boot the machine and everything would be resetted for him. I know there are many methods of creating/loading an image of a drive, but the ones I've found so far have complicated menus with several options to choose from, etc. Ideally, perhaps only asking a Yes/No question such as "Would you like to reinstall?" would be great. Does such a tool exist? Thank you in advance!
