Question about 'hosts: cluster' entry in /etc/nsswitch.conf

Hi~
my system have "hosts: cluster files dns" entry in /etc/nsswitch.conf.
I know 'files' to see the '/etc/hosts'.
I want to know that 'cluster' to see 'what file'.
Thanks,

'cluster' denotes internal lookups, i.e. no file on the file system. If I recall correctly, it allows the system to look up the cluster interconnect private addresses.

Alsa entries in /etc/modprobe.conf

could someone who has all the alsa options compiled as modules post that part of their /etc/modprobe.conf? i'm only getting 3 lines and i believe there are supposed to be more, causing me to have to run alsaconf every time after booting. for some reason the other modules aren't getting written to the file. appreciate!

Questions about hosting and integration of jsp

hi,
I have been searching about jsp for a while and i need to ask some question which confuse me.
First, I have been looking for hosting for jsp but i haven't yet found a useful one.
And hosting is pretty expensive than php hosting especially in turkey. Do you suggest some international hosting which price is agreable. Also I couldnt find any commercial site (except ibm, java.sun) which is implemented in jsp, if you know some, give some instance.
Php is much more widespread than jsp. but it still has some disadvantages of being opensource. but lately, I have read an article about sun has started to support php, According to this supprort, can php has an advantage on jsp.

Dear dudushr,
This is not at all a pbm.
what u can do is,
write ur servlet class and configure that in ur web.xml.(put servlet class in ur WEB-INF/classes dir)
now in the action part of form tag call the url (just configured in web.xml) for this servlet.
after executing the query and doing further process within the servlet ,use RequestDispatcher's forward method to pass this values to ur jsp.
try it and let me know..
cheers..

Question about nouveau wiki entry (keep both drivers installed?)

In this section:
https://wiki.archlinux.org/index.php/No … _installed
It talks about ways to keep both drivers installed. As far as I can tell both drivers cannot be installed at the same time because of the conflicting packages "mesa-libgl" and "nvidia-libgl". Is there in fact a way to have both of these packages installed? Seems like in that entry section there is a lot of useful information. Not sure which sections to keep and which to rename / move etc.. Wanted to put up a discussion about this first to see what needs to be done if anything.
Last edited by dodo3773 (2013-12-10 20:28:39)

I agree on "keep both drivers installed" issue.
I've done some modifications to the nouveau -> nvidia and the other way round scripts, too (so they'll install/ uninstall the way they should). Might add that tomorrow.

Question about host and local machine and applet

hello,
I have a question. I'm writing an applet program that will write a specific file in its working directory in the host machine.
1)How can i get the working directory of the applet?
2)How should i specify the path for writing on a file in the applet directory?

>
Can an applet write a text file to its own path in the server(or in a folder in its own path)>No. Or at least, not without help from the server.

Question about the Cluster and Column width in Graphs in Illustrator CS2

How do they relate to each other? How do the Percentages work together? Is there any information about how you can mathematically figure how much area each Cluster width takes. If you make a graph and make both the cluster and column widths 100%, the entire area is filled. If you make the Column width 50% the bar will sit exactly in the center of the Cluster width, but if you make the cluster width 75%, the bars move closer together.

Gregg,
The set of bars that represent each row of data in the graph spreadsheet is called a "cluster".
Let's let
   W = the width of the whole area inside the graph axes
   R = the number of rows of data
   C = the number of columns of data
Then the maximum potential space to use for each row of data is W/R. The cluster width controls how much of this potential space is assigned to each row. This cluster space is then divided by C, giving the maximum potential width of each bar. The maximum potential width for each bar is then multiplied by the column width percentage to get the actual width of each bar.
So the actual width of each bar is ((W/R)*Cluster width)/C)*Column width
The graphs illustrated below have three rows of data, with two columns each. The solid colored areas in the background have the same cluster width as the main graph, but they all have a column width of 100%. This lets you see more easily how the gradient bars that have a column width of 80% are using up 80% of their potential width.
Notice that as the Cluster percentage gets lower, the group of bars that represent a row of data get farther apart, so that you can more easily see the "clumping" of rows. When the Cluster percentage is 100%, the columns within each row are no closer to each other than they are to the columns in other rows.
As the Column percentage gets lower, the bars for each data value occupy less of the space within their row's cluster, so that spaces appear between every bar, even in the same row.

Dumb question about user_sdo_geom_metadata DIMINFO entries

I'm sure that this is a dumb question!
I create a new entry in user_sdo_geom_metadata as follows...
INSERT INTO USER_SDO_GEOM_METADATA
VALUES ( 'PR_A', 'GEOM',
MDSYS.SDO_DIM_ARRAY(
MDSYS.SDO_DIM_ELEMENT('X',190000.0,640000.0, 0.05),
MDSYS.SDO_DIM_ELEMENT('Y',120000.0,680000.0, 0.05)
NULL );
But when I select the DIMINFO from the table...
SQL> select diminfo from user_sdo_geom_metadata a where table_name = 'PR_A';
DIMINFO(SDO_DIMNAME, SDO_LB, SDO_UB, SDO_TOLERANCE)
SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', 190000, 640000, 0), SDO_DIM_ELEMENT('Y', 1200
00, 680000, 0))
The sdo_dim_element and sdo_tolerance
elements show no decimal places.
Is this because I have not set some
display number format option in SQLPLUS
or for some other reason?
regards
Simon

Simon,
If you are using an old sqlplus client
(815) then you won't be able to see the decimal places in the diminfo object.
But if you hace a newer (816/817) sqlplus
client you should be able to see the decimal places.
If you are not seeing them in these clients
then there might be some format paramter set
to show numbers without decimals.
You can do a
show numformat
in sqlplus to see if there is any format set for that paramter.

Recovering from crash. Questions about iPhone andiTunes library files, etc.

Hi all - Had a major system crash which I'm trying to recover from. My iTunes purchases are backed up, as well as the iTunes application folder and everything contained within.
Anyway, I've reinstalled Window and iTunes and have all my iTunes purchases up and running, but have a couple of questions.
1) My new iTunes install thinks my iPhone is still synced to another iTunes library and wants to Erase and Sync to connect it to this new one. I'd obviously like to be able to sync without erasing, so are there settings and library files from my backed up iTunes directory that I can copy over to my freshly-installed iTunes directory to allow this to work?
2) Similarly, if there is a way to do this, will I be able to connect my old iPod that was also synced to my old iTunes and copy over the non-iTunes purchased songs? I have my CDs, no no real worry -- just would be simpler this way...
Thanks!

Assuming you have the default itunes setup, if you backed up your c:/.../music/itunes folder, it has the itunes database in it.
iTunes Library.itl
If you didn't make a backup of that folder and do not have the ITL file, you can try getting playlists,ratings, playcounts etc back from the iphone by using a 3rd-party ipod manager.
This ilounge article explains it more;see page 3
http://www.ilounge.com/index.php/articles/comments/copying-music-from-ipod-to-co mputer/
Make sure it supports iphone - not all of the other programs do.

Interactive Reports - Question about Downloading PDF, CSV, Email, etc

I recently installed the latest version of APEX. I deployed it as an EAR on Oracle WebLogic. I then created a simple
interactive report that has the search bar above the report. The downloads (emailing, pdf, etc) do not work after I
run the report.
What setup\configuration is required to get the emailing and downloading of the other files to work?
fyi: right now I have Oracle WebLogic, Oracle 10g, and APEX running locally on a XP based laptop.
Thank you in advance,
Wes

Hello Wes,
Sending a report as an email requires an SMTP server. You need to configure your instance settings to point to the SMTP server.

Question about host identifier definition

Hi,
I've created a webgate and define the "Preferred HTTP Host" as the hostname where the web app is deployed. It seems ok that the webgate will protect the URL containing the hostname. But after I've authenticated, when I change the hostname to the IP address directly in the same explorer and request the resource again, it will ask me to re-authenticate. In my expectation, I don't need to re-authenticate....
Is there anything wrong with my host identifiers defintion? I've already added the corresponding IP address into the host identifier list.
Please help to give me some advice, thanks.

Hi,
The host identifiers are OK, this is happening because the web server first sets the cookie for the servername, and does not accept it for the n.n.n.n name - effectively you are using different domains (from a cookie perspective), even though it is the same web server. To solve it, you could just put the server name in the Challenge Redirect parameter in the authentication scheme to
http://servername.mydomain.com
and then OAM will set the cookies as necessary, exactly the same as configuring OAM for multi-domain SSO.
Regards,
Colin

Question about discovering Cluster DB in EM 12c

Hi dear experts,
Please suggest me what do you use SCAN name or PUBLIC IP when want to
discover Oracle DB/Listener/ASM using
*"Add Non-Host Targets Using Guided Process (Also Adds Related Targets)"* option
and your DB and ASM is clustered?
P.S. I use SCAN name instead of hosts IP that found EM 12c.

I changed from SCAN name to hostname and also changed the role
from sysasm to sysdba and it able can connect.

Question about hosting - Flex/Coldfusion

I'm wanting to use Flex to display Coldfusion info.
just went through the tutorial at http://www.adobe.com/devnet/flex/articles/fcf_getting_started_coldfusion_flex_02.html and I got the example to work on my local machine. I was also able to do the same with my own data. But the example uses remoting services and I don't know what my hosting providers have on their servers.
I'm using CrystalTech.com, which is an Adobe partner. But they said they didn't offer Flash remoting on their shared servers.
I'm not sure if Flash remoting is what I need to get Flash to access the cfc's.
Can someone tell me if I need to switch hosts (which would be a real pain) and look for a host that has Flash remoting or if that is even what I need?
Thanks,
Richie

A bit odd.. I haven't come across any shared hosting with Remoting disabled yet.
Have you tried accessing the remoting gateway?
Should be something like:
http://yourdomain.com/flex2gateway/
You normally get to see a blank page.
If remoting is disabled, you should still be able to access Coldfusion CFC's as webservices.
To achieve this, simply add "?wsdl" to the url of the cfc - without the quotes.
Here's an example:
http://muzakdeezign.com/services/be/pylos/site/NewsSelect.cfc?wsdl
In Flex you access them using a WebService tag instead of a RemoteObject tag.

Basic questions about hosting

hi everyone, i hope i am posting in the correct forum...
i have just finished a website (designed with dreamweaver) and i am ready to upload it online. the website is very simple (html), has no flash or animations, only pictures and has a total 50MB worth of files.
i am having many troubles deciding how to book a suitable hosting and monthly traffic for the website. I hear that 1GB monthly traffic limit might be enough. I don´t know how this exactly works but what i think is that if someone visits the website and checks every single picture, is that already 50MB traffic just from that one visit??
plus, i am overload with options from different hosting providers and it´s very hard to know which are over priced and which are the most reliable ones. it´d be great to know from other people´s experience which are the best providers.

Hi--
I don´t know how this exactly works but what
i think is that if someone visits the website and
checks every single picture, is that already 50MB
traffic just from that one visit??
Yes, that's pretty much right. It might be somewhat less than 50MB, though. Some website elements, like your style sheet, might be cached by the visitor. In that case, they might only load once per visit, reducing the traffic counted against you.

Security question about hosting multple websites at ~/Sites

Hi All, I wish to host multiple websites from my server running Mac OS X Server 10.4. I just wanted to know if there are any security risks involved in having sites running from the path ~/Sites. ie /Users/username/Sites/ I am running the machine as a standalone server with port forwarding from my router. Other: Running PHP 4 and MySQL 4 aswell. Is this the wrong way to host sites? If so, do you have any suggestions for other paths that may be more secure? Would it be more secure to host them from the default location /Library/WebServer/Documents? I have FTP set up so that authenticated users see home directory only and have set up users home directories as /Users/username/Sites in the workgroup manager. Is there a better way to set this whole thing up? Am I screwing it from the start? Thanks in advance...

If the user directories are just for hosting sites, the user's won't be using them to store their stuff with an expectations of privacy, there's no inherent insecurity doing it this way. If the users were using their home directories, then it may come as a shock that the read and browse permissions have to be turned on so that the web server can get to the Sites folder to serve pages.
MySQL is a popular database. I would venture to say that most database insecurity is the fault of the DBA, not the database itself.
PHP scripts are listed in the security ezines a lot. I don't know whether PHP is inherently insecure, so simple that people who really don't know how to program can program with it or other reasons.
OSX server isn't an OS I'd trust exposed to the Internet. Apple's done things that make it at least very hard, if not impossible (I haven't really sat down and fought it) to lock it down well.

Question about synchronized re-entry

Suppose I have the following code:
* method performs actions that require synchronization on state but
* the programmer ensures manually that it is only called in a context
* where we are already synchronized on state
private void veryPrivateMethod() {
    //synchronized(state) { (*) required?
    if (state == 999) {
        // perform actions that require synchronization on state
public void anotherMethod() {
    synchronized(state) {
        if (state == 42)
            state = 43;
        veryPrivateMethod();
}See (*): If I ensure manually that veryPrivateMethod will only be called in a context where we are already synchronized on state, do I still need to specifically synchronize on state in the method (reentrant synchronization), or will it be better performance-wise and still safely synchronized if I omit the synchronized statement in veryPrivateMethod()?
Thanks!

Its not a bad idea, as long as you realize that doing this has no special meaning and will offer no special protection. You can synchronize on just about any object you want, as long as other threads synchronize on the exact same object when wanting to execute the same section(s) of volatile code.the comment in the example is:
// perform actions that require synchronization on statethis leads me to believe that the code is not correctly synchronized currently. like i said, changing the reference to the object you are synchronizing on pretty much always leads to broken code.
