Beginners Question - cluster config

Hi,
Is it possible to configure three Sun E10000 nodes in a cluster so that the first 2 nodes will be in scalable mode with dynamic load balancing and and the third in failover mode?. The application running is a web server with Oracle databse at the back end. The node in failover mode is meant for disaster recovery.
Also I would like to know if Sun Cluster 2.2 supports this type of configuration.
Thanks in advance
Binu

Sun Cluster 2.2 does no support scalable services so could not be used for this type of configuration.
SC 3.0 could be used with a web server configured as a scalable service and Oracle running as a failover service within the same three node cluster.
Hope this answered you question

Update issues when ESA Virtual replacing C170 Appliance in Cluster Config

I have opened a TAC ticket on this one but was curious if any others experienced the same issue.
I have C170s in Centralized ClusterConfig. I recently learned about the Virtual ESAs after reading about the EOL for C170s in a few years. I think the Virtual ESAs will add a lot of flexibility. The only issue I've noticed was trying to join Virtual ESAs to our Cluster are updates so far.
The first virtual ESA I brought up I was able to initially update it so it could join the cluster. I thought maybe I messed up the network config somewhere. So after messing with it over the Weekend and opening a TAC case with Cisco. I thought I would try configuring the second Virtual ESA. Sure enough updates are working, and no errors. Hooked it up enough to do some quick testing to make sure the listeners were working. Feeling pretty good about it, I join the cluster. Everything copied over configuration wise, I also setup a new ClusterGroup for the Virtual ESAs so I could customize the listeners and interfaces. Before I got too crazy I quickly realized that my updates stop working on the second virtual appliance.
So just curious if there are some configuration compatibility issues between appliance hardware and Virtual we should be aware of. I found some great information from the Forums about forcing updates and reading the tail of the updater_logs, which produced the following:
Info: Dynamic manifest fetch failure: Received invalid update manifest response
I found the fix for non-cluster configured Virtuals for this Update error:
http://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/118065-maintainandoperate-esa-00.html
But this does not for for clusterconfig.
So is my best course of action to:
run the clusterconfig on one of my virtuals,
Remove Virtual from ClusterConfig after config is migrated
Apply CLI fix to point post-cluster config Virtual so it now points to the right update servers
Create new cluster with the now fully Updating Virtual-Uno ESA
Join Remaining virtuals to the newly created cluster and phase out the old physical cluster?
Obviously I left out all the fine details about MX records, IP addresses, Central Reporting and Spam and outbreak reporting. Just want to make sure I'm not missing something, maybe tare down the old clusterconfig first, set it to point to the update servers in the article above. Then I can phase out my old physicals later on down the line as they break down over time and avoid configuring two clusters for every rule change.

So it looks like I have found the answer to my own question. Looks like the fix in the following article does apply to Virtual ESA in a cluster.
http://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/118065-maintainandoperate-esa-00.html
Some things I'd like to figure out is, will this change stick, will new virtual nodes pick up the incorrect update URL when I join them to the cluster? I made the changes and all my hosts seem to be updating fine. Will wait and see how well they do over the next few days and let them bake in a little before I push e-mail through them.
Step by Step how it looks with a cluster config from the CLI:

Way too beginners question...

Hi Gentlemen,
I am just thinking of learning this technology,and have few very beginners questions to start my quest.
1. Can I read any type of cards that have a chip on them?
2. Do I need any particular reader/writer device or java can work with every type.
3. Since I am beginner is there a tutorial that step by step walks you through how to run an example program or that teaches how to read or write from/to a card using any/ or a specific reader/writer device.
4. I had hard time understanding the docs that come with the reference implementation docs.
5. Is there a book you guys can recomend.I really appreciate it
Thanks

1. It's not so tricky. There are many cards with many OS types and derivatives on the market and the level of incompatibility is rather high. For the JavaCards - they are typically initialized with 3DES ECB keys that one have to know in order to retrieve context. So if you do not know this ....
2. Many tools are depending on standard PC/SC IF provided with every win system. So if your reader was configured to work well without your JC IDE or whatever you use - the chance you will have no problems is big.
3. Again, there are nice examples provided with Jcop tools ... although the article is also not bad. But it is much readings .... I always try to figure out what the code means ... and then do readings ...
4. Yep, Java is like must ... but u can figure this out ... it is named JavaCard ... ain't no coffe ...
5. Chen is one nice Lady and book is also nice. But Alchemist is Alchemist ...

Logs for cluster config change

Hi,
I've noticed some rather odd behavior on my cluster configuration. Before, in our production, I noticed who ever did the
orginal config put the admin server as part of a cluster. I'm looking at it now a month later and see that the admin is
not part of the cluster.
Is there any part in any of the logs where it might show that someone removed the admin server from the cluster?
Any advice would be appreciated.
Thanks..

Question Cluster/Load balancing

Question about iplanet load balancing/Cluster:
Following discussion are based on iAS C++ engine(kcs).
We have four web servers and two iAS servers:
Web1, Web2, Web3, Web4
iAS1, iAS2
All machines run Solaris 8, web server is iWS4.1 SP6,
Application server is iAS6.0 SP2, and both iAS boxes have
same hardware configuration.
1. What's the best load balancing method for this structure?
Per Server Response Time(Web Connector Driven)
Per Component Response Time(Web Connector Driven)
Round Robin(Web Connector Driven)
User Defined Criteria(iAS Driven)
2. What's the criteria for the kxs engine to choose the kcs
engine to sent request if we set Web Connector Driven
load balancing?
3. If we set iAS driven load balancing, what's the criteria
for the web connector used to choose kxs?
4. We got a problem when run load testing for an AppLogic
in this cluster, one iAS CPU average usage got almost
100%, but the other one is just 70%.
We used Per Server Response Time load balancing method.
Thanks.

it depends on the characteristics and behaviour of your application

2. What's the criteria for the kxs engine to choose the kcs

kxs always does round robin to the kjs or kcs engines. The webconnector
selects the kxs to which to send to.
>
3. If we set iAS driven load balancing, what's the criteria
for the web connector used to choose kxs?
as specified by your criteria in the iAS driven section.
The ias instance will send its current list of preferences for ias
intances it got from the criteria to the webconnector. This information
is dynamic and updated constantly.

again, this can be a valid result depending on the way your applogics
are written. Are they CPU bound, I/O bound or DB bound? Since individual
components execute differently and you specified to use the average of
those results to determine load balancing this can be a valid result
because differences in execution times of your applogics.

Basic questions about config backup/restore

I've searched around with limited success. I've just inherited the Ironport devices in our enviornment and need to perform an OS upgrade of our cluster. Prior to doing so, I want to backup each members config file. (also, I want to do this before doing any config changes)
If I back up each member's config to the device, how I can access/edit these config files so I can replaced the masked password fields with the actual passwords?
I'm aware of the unmasked/hashed password version of the file, but we'd like to avoid that if we can.

The config file itself is just a text/xml file and most good text editors (vi/textpad) will handle it easily.
Even when passwords are not masked, they are always encrypted. The only way to manually insert a password would be to encrypt it and put the result back in the config file.
As long as you are choosing strong passwords (hint) it is not at all an easy task to force decrypt the hashed password string. Even if you are completely paranoid, just store the config file somewhere in an encrypted format.
Bottom line: don't mess up your "backup" by manipulating it in a way that could render it useless just when you most need it. Manual editing of config files is tricky and AFAIK not officially supported in any way.

Oracle9i installation on Sun cluster not showing the cluster config screen

Hi All,
We are trying to install Oracle 9i RAC on a 2 node Sun cluster. The oracle installer never shows up the cluster configuration screen. However if we run the preInstall checker script from oracle (Installprecheck.sh) , it reports that it has indeed detected the cluster. Can anyone please help us out of this predicament.
-Kishore

Hi Kishore,
I 'm assuming the following:
. Sun Cluster 3.1 will be used to support Oracle 9i RAC
. Oracle is being installed on a file system instead of raw devices
To answer your question, a clustered file system must be present in order for Oracle 9i RAC Installer to recognize that a cluster exists before it displays the cluster configuration screen at the beginning of the installation.
Prior to QFS 4.2, Sun did not support a clusteed file system. All Oracle RAC systems for Solaris were raw device based. You're in luck now because Sun has released Sun QFS 4.2 which support a clustered file system.

HFM Config - Cluster Config

Hi,
I have a "working" HFM environment. I lost some servers due to a hardware failure and I want to re-run the config utility to remove those servers from the Cluster.
I run the EPMA Confg utility and the "Confgiure Cluster Application" and "Register Application Servers/Cluster" is failing.
I even tried to create a new cluster name to see if that would solve the problem.
In the config error log file I get a lot of details
(Nov 05, 2010, 01:20:26 AM), com.hyperion.hit.registry.ComponentImpl, ERROR,
java.net.UnknownHostException: <Servername>
But this <ServerName> does not appear in my cluster list, in fact it is one of the machines that crashed.

Cluster config. - toplink cache

hi all!
A simple question...
I've built an application using ADF and toplink.
Actually the application runs on a single IAS.
now, for load reasons, i'll need to migrate to a cluster configuration.
Is there any kind of problem with the toplink cache?
Thanks.

Meter / slider questions - cluster names, changing needle colour

OK, so a couple of questions about meters /sliders.
I have a meter indicator on a form, with two needles. (example attached)
I want to create the cluster for the input using "bundle by name", but the meter "cluster" does not appear to have any names. I want the elements of the cluster to be "Channel 1" and "Channel 2" - how do I do this?
Secondly, I want to be able to set the needles to transparent.
I can do this with a meter with only one needle, but for more than one, I think you need to set the Active slider ("Actslider") property.
It strikes me that the easiest way to do this is to use a loop, but how do I discover how many needles the meter has? Or could I use the cluster names to s
pecify which needle I want to change colour?
TIA

Thank you both for the responses, and apologies for the tardy reply - changing priorities, etc, etc, you know how it is...
I've attached a Vi to act as an example for anyone else who has either of these problems.
The main thing I found out is that although you can, as you say, use a constant to "declare" the cluster names for the gauge, these names are only "remembered" by the wire - if you create a local variable of the gauge, it will NOT remember the cluster names. That's what had me confused...
Cheers

Beginners question - making sense of form, item, pane & variable (with relation to where data is stored in the SQL database)

Hi Everyone,
I am new to writing reports (SQL code) for SAP, however I am aware that inside SAP Business One it is necessary to enable System Information (from the View menu) in order to see which tables (and related table attributes / column names) are related to various aspects of the various SAP 'modules' (e.g.: A/R Invoice).
Using an A/R Invoice as an example I can see at the row (or line) level that an item with the description of 'Opening Balance Transfer' is contained in the table INV1, within the attribute (or column) called Dscription.
However not every 'on screen object' shows a table / attribute. For example in the same A/R Invoice if I hover my mouse over the Balance Due field all I see is Form related information.
My question is 'How do I make sense of the Form, Item, Pane, Variable information?', with relation to where data is stored within the SQL database?
Links to online tutorials explaining how this feature of SAP Business One will be much appreciated, along with any personal advice regarding working with this information.
Any (and all) help will be greatly appreciated.
Kind Regards,
David

Hi David,
1.Here I am explaining use of each field except pane
a. Form ---> Used in additional authorization creator
b. Item, column--->Useful in creating Formatted search queries (FMS)
c. Variable --> Some of the field values based on another values. ie. indirect values.
d. INV1---Table name
2. How to get variable?
As per your second attachment, to get balance due ,you need doc total field from OINV table. For example,
SELECT T0.[DocNum], T0.[DocTotal] FROM OINV T0 WHERE T0.[DocNum] = 612004797
Thanks & Regards,

anyone out here who can help me?
thanks in advance,
stefan

ok, i use :
tomcat 5.5
myfaces 1.1.4
jre 1.5.0_09
anything more you need? as i said in the topic, i�m a real beginner with this..
and one more thing that i don�t understand :
all example applications that come with the book that i�ve read are working perfectly with this configuration, but when i try to start my own app i get this error. quite strange for me..

Exporting a table to an EPUB (a beginners question)

Epub beginner.
I trying to teach my self how to create an EPUB, I have watched many tutorials
from Adobe and beyond all very useful and educational.
I am using Indesign CS5.5
Question 1:
What is the best way to export a ‘table’ to an EPUB doc’ that has dingbats/bullets/ticks in columns,
when I create a EPUB the bullets/dingbats/ticks change to a font. Would it be better to make a ‘jpeg’
of the ‘table’ then import back into indesign via the Articles Panel?
Question 2:
As a side issue, Is there a way by just using the bullets command to have a single bullet with no text
so to use in a table instead of using Wingdings etc?
Thanks in advance for your help.

@Derek – just some questions on this:
How about converting the table to a row of text frames grouped together and anchored to the main story?
Just a "wild" idea, I know. Would that better the situation? I mean not to be forced to render the table to pixels? That could be an ugly thing.
Or would be grouped text frames also be rendered to pixels by InDesign CS5.5's export to EPUB?
And about the bulleted paragraphs:
What, if we convert the bullets to live text?
Ok, we'll likely get a font rendering issue with a font that cannot be included or if included cannot be rendered on the device. Only the substitute of that font, whatever that subsituted font will be.
Or forget about the bullets formatted with text attributes and use vector shapes or anchored images in PNG format (PNG with transparency maybe)?

Beginners Questions about Multiple JPanels in JFrame and event handling

I am a newbie with SWING, and even a newerbie in Event Handling. So here goes.
I am writing a maze program. I am placing a maze JPanel (MazePanel) at the center of a JFrame, and a JPanel of buttons (ButtonPanel) on the SOUTH pane. I want the buttons to be able to re-randomize the maze, solve the maze, and also ouput statistics (for percolation theory purposes). I have the backbone all done already, I am just creating the GUI now. I am just figuring out EventHandlers and such through the tutorials, but I have a question. I am adding an ActionListener to the buttons which are on the ButtonPanel which are on JFrame (SOUTH) Panel. But who do I make the ActionListener--Basically the one doing the work when the button is pressed. Do I make the JFrame the ActionListener or the MazePanel the ActionListener. I need something which has access to the maze data (the backbone), and which can call the Maze.randomize() function. I'm trying to make a good design and not just slop too.
Also I was wondering if I do this
JButton.addActionListener(MazePanel), and lets say public MazePanel implments ActionListenerdoesn't adding this whole big object to another object (namely the button actionlistener) seem really inefficient? And how does something that is nested in a JPanel on JFrame x get information from something nested in another JPanel on a JFrame x.
Basically how is the Buttons going to talk to the maze when the maze is so far away?

I'm not an expert, but here's what I'd do....
You already have your business logic (the Maze classes), you said. I'm assuming you have some kind of public interface to this business logic. I would create a new class like "MazeGui" that extends JFrame, and then create the GUI using this class. Add buttons and panels as needed to get it to look the way you want. Then for each button that does a specific thing, add an anonymous ActionListener class to it and put whatever code you need inside the ActionListener that accesses the business logic classes and does what it needs to.
This is the idea, though my code is totally unchecked and won't compile:
import deadseasquirrels.mazestuff.*;
public class MazeGui extends JFrame {
JPanel buttonPanel = new JPanel();
JPanel mazePanel = new JPanel();
JButton randomizeB = new JButton();
JButton solveB = new JButton();
JButton statsB = new JButton();
// create instanc(es) of your Maze business logic class(es)
myMaze = new MazeClass();
// add the components to the MazeGui content pane
Component cp = getContentPane();
cp.add(); // this doesn't do anything, but in your code you'd add
            // all of your components to the MazeGui's contentpane
randomizeB.addActionListener(new ActionListener {
    void actionPerformed() {
      Maze newMaze = myMaze.getRandomMazeLayout();
      mazePanel.setContents(newMaze); // this is not a real method!
                                      // it's just to give you the idea
                                      // of how to manipulate the JPanel
                                      // representing your Maze diagram,
                                      // you will probably be changing a
                                      // subcomponent of the JPanel
solveB.addActionListener(new ActionListener {
    void actionPerformed() {
      Solution mySolution = myMaze.getSolution();
      mazePanel.setContents(mySolution); // again, this is not a real
                                         // method but it shows you how
                                         // the ActionListener can
                                         // access your GUI
// repeat with any other buttons you need
public static void main(String[] args) {
    MazeGui mg = new MazeGui();
    mg.setVisible(true);
    // etc...
}

WHERE Ask Beginners' Questions???

Obviously this isn't the forum for having beginner's questions answered. I've asked two and nobody responded. Is there a list where newbies can get help?
beno

This forum is just fine for any level of questions.
1) Your first question received an answer but you apparently couldn't follow it. Though using f8 wasn't mentioned, the only place you might use Ctrl-F8 in those instructions would be the first step, though there are a couple of ways to create a new mc. All of the steps are fairly clear to follow, so if you do not understand one of them, just ask (and be patient).
