Static, public, private, protected?
Sorry for these questions, but I still don't know why properly why you use static, prublic, protected?
And also is it possible to have a multi array first bit being and short and second being a byte e.g.
int item_id[] byte[]so item_id[0][0] = 5
first 0 means you got nothing on
second 0 is the hp stat
= 5 adds 5 hp onto the total is this possible

Look at this and this .
And also is it possible to have a multi array first bit being and short and second being a byte e.g.Why would you want to do that? If you feel like using wrapper classes, you can make an array of Objects.

Inheritance: public, private, protected & default?
I have a good idea where, and when, to use public, private and protected, but what is the default used for? By default I mean just not specifing the inheritance.
Ex:
String aString;
Thanks in advance,
BrianIt means basically that only classes written to the same package as that one, would be able to access the member, regardless of whether they inherit from the class or not. If a class inherits from it, but is not written in the same package, it cannot access the member - it's just as if it were written as "private" in that case.

Forcing invocation of private/protected methods
Has anyone, any idea how can be forced the invocation of a private/protected method on a object. The client that invokes the method has a reference to the object and is declared in a different object than the targeted object.
See code below:
package src.client;
import java.lang.reflect.Method;
import src.provider.CPBook;
public class Tester {
public static void main(String [] args) {
CPBook targetObj = new CPBook();
Method [] mths = targetObj.getClass().getDeclaredMethods();
Method targetMth = null;
for (int i = 0; i < mths.length; i++) {
if ("getMgr".equals(mths.getName())) {
targetMth = mths[i];
if (targetMth != null) {
try {
Object [] obj = new Object[1];
obj[0] = new Boolean(true);
targetMth.invoke(b, obj);
} catch (Exception e) {
e.printStackTrace();
package src.provider;
public class CPBook {
public void startDownload() {
public void stopDownload() {
protected void getMgr(boolean bool) {
System.out.println("------- OK ------- : " + bool);
}Thank you.
Best regards.The class java.lang.reflect.Method has a setAccessible(boolean) method on it. I think that's what you're asking for. Code that makes use of it might run into trouble if a security manager is involved, though. Generally, methods are private for a reason, too, so if your code depends on a private method, it's dependent on an implementation detail it probably shouldn't be concerned about, or even aware of

Can someone help me in understanding Public ,Private ,VIP&SCAN for RAC11gr2 as i am new to RAC 11gr2 installtion processThe public IP address is assigned dynamically using dynamic host configuration protocol (DHCP), or defined statically in a domain name system (DNS) or in a hosts file. It uses the public interface (the interface with access available to clients).
Oracle Clusterware uses interfaces marked as private for internode communication.
The virtual IP (VIP) address is registered in the grid naming service (GNS), or the DNS. Select an address for your VIP that meets the following requirements:
* The IP address and host name are currently unused (it can be registered in a DNS, but should not be accessible by a ping command)
* The VIP is on the same subnet as your public interface
Oracle Database 11g release 2 clients connect to the database using single client access names (SCANs). The SCAN and its associated IP addresses provide a stable name for clients to use for connections, independent of the nodes that make up the cluster. SCAN addresses, virtual IP addresses, and public IP addresses must all be on the same subnet.
The SCAN is a VIP name, similar to the names used for VIP addresses, such as node1-vip. However, unlike a VIP, the SCAN is associated with the entire cluster, rather than an individual node, and associated with multiple IP addresses, not just one address. -
Inheritance and access control - "private protected"
I'm reopening an old topic, seems to have been last discussed here 2-3 years ago.
It concerns the concept of restricting access to class members to itself, and its subclasses. This is what "protected" does in C++ and "private protected" did in early versions of the Java language. This feature was removed from Java with a motivation along the lines of not being "simple", and "linear" (in line with the other access modes, each being a true subset of the next). Unfortunately, the article which explained Sun's position on this keyword combination seems to have been removed from the site, so I haven't been able to read its original text.
But regardless of simplicity of implementation or explaining Java's access modifiers to newbies, I believe it is a fundamental part of OO programming for such an access mode to exist. The arguments for having the standard "private" mode in fact also apply for having a C++-style "protected" mode. (Arguing that classes within a package are related and it therefore doesn't hurt to also give them access to Java's "protected" members, is equally arguing that "private" is unneccessary, which noone of course believes.)
The whole concept of inheritance and polymorphism and encapsulation builds on the access modes private, protected, and public (in the C++ senses). In Java the "package" concept was added - a nice feature! But I see no justification for it to negate the proper encapsulation of a class and its specializations.What effect upon inheritance other than hiding members
from subclasses is there?
None. And I cant think of another declaration that prevents members from being inherited but private.
Of course the onus comes on the programmer with Java's
definition of "protected" - but
1) there is rarely a single programmer working within
a package
The point was the package is a unit which does not hide from itself. Just like all methods within a class can see each other, all classes within a package can, and all packages within a program can.
2) it muddies the encapsulation in the design - when
you see a "protected" method someone else, or yourself
some time ago - wrote, how do you know if the design
intention is to have it accessed solely by the class
and its subclasses, or if it is indeed intended to be
shared with the whole package? The only way to do
this today is to always explicitly specify this in the
comments, which may be lacking, inconsistent, and
abused (since it isn't enforced).Encapsulation would be implementation hiding. Not method hiding. The only thing you should probably allow out of your package is an interface and a factory anyway.
I understand where you are coming from, but I really have not had occasion to take issue with it. I can't think of a real codeing situation where this is required. OTOH, I can't think of a coding situation where I need to access a protected method from another class either. -
Oracle Database RAC 11gR2 : Role of Public,Private,Virtual, and SCAN IPs.
Hi Experts,
1. Can you please let me know why do we need configure below IP addresses for RAC setup and what is the role that each one plays ?
- Public
- Private
- Virtual
-SCAN
2. What is the relationship between SCAN IP and Virtual IPs ?

- PublicConfigured before installation for each node, and resolvable to that node before installation.
Role:
Allow communication/configuration of Virtual/SCAN between the nodes of the cluster. Without Public Interface/IP the Clusterware don't start.
The Virtual/SCAN will work as alias IP on Public Interface over Public Network.
- Private or InterconnectConfigured before installation, but on a separate, private network, with its own subnet, that is not resolvable except by other cluster member nodes
Role:
Clusterware uses the interconnect for cluster synchronization (network heartbeat) and daemon communication between the the clustered nodes.
RAC uses the interconnect for cache fusion (UDP) and inter-process communication (TCP).
Cache Fusion is the remote memory mapping of Oracle buffers, shared between the caches of participating nodes in the cluster.
- VirtualConfigured before installation for each node, but not currently in use. On the same subnet as all other public IP addresses, VIP addresses, and SCAN addresses.
Role:
The goal is application availability. If add or remove nodes it's necessary make config your client adding/removing VIP (with SCAN it's not necessary)
When a node fails, the VIP associated with it is automatically failed over to some other node.
Without using VIPs or FAN, clients connected to a node that died will often wait for a TCP timeout period (which can be up to 10 min) before getting an error.
As a result, you don't really have a good HA solution without using VIPs and FAN. The easiest way to use FAN is to use an integrated client with Fast Connection Failover (FCF) such as JDBC, OCI, or ODP.NET.
-SCANThree Static IP addresses configured on the domain name server (DNS) before installation so that the three IP addresses are associated with the name provided as the SCAN, and all three addresses are returned in random order by the DNS to the requestor
Configured before installation in the DNS to resolve to addresses that are not currently in use. On the same subnet as all other public IP addresses, VIP addresses, and SCAN addresses
Role:
The goal is application availability before clients establish communication with RAC and make the Cluster-Wide totally transparent.
SCAN IP is a new "layer" network (oracle) with high availability that allows you to change the characteristics of your cluster (i.e add/remove nodes) without the need to make configuration changes in their clients "Grid concept".
>
2. What is the relationship between SCAN IP and Virtual IPs ?SCAN IP is used to receive new connection requests and redirects to the VIP IP.
The Virtual IP establishes and allow failover of the connections after connection being established.
When the client requests a connection, Oracle Client 11gR2 find for IPs available for this host-scan and create a list of all SCAN IP the first connection attempt on RAC is using one of SCAN IPs avaliable.
The SCAN Listener will receive this connection and re-direct to one of avaliable nodes using LOCAL_LISTENER from this point the the connection is established using Virtual IP (VIP).
All SCAN/VIP must be resolved by DNS.
The client knows that there is only the SCAN Hostname, which is configured in the connection string.
Once the connection is requested Oracle Clusterware redirects the connection to one of the VIP hostname which must be resolved by DNS.

I guess I haven't looked at my Java language spec in awhile (or never did very closely), but I was surprised today to find out that the "protected" specifier allows subclasses as well as any classes in the same package. I feel this is a little too much access for my tastes.
I guess the idea here is that one developer/group will be desigining a package as a whole and will not do anything advertant or malicious with another class' protected members.
http://java.sun.com/docs/books/tutorial/java/javaOO/accesscontrol.html
I noticed that in Java 1.0 also had a fifth specifier as "private protected" that is no longer supported. Was this the sought-after protection that I am looking for? What was the reason for not providing something like this?
Btw, my C++ is also a little rusty around the details, but does the "protected" specifier do the same thing with namespaces or something?The point of such silly code (below) is simply to demonstrate that that no one should be allowed to change the key's code except the Key. If I want to subclass a Key, I shouldn't be forced to make "Key.Code" private and re-implement Code again in my subclass. From an object-oriented perspective, I still feel that "protected" should only be valid from within sub-classes and have a 5th specifier that specifies both package and subclass.
A colleague of mine pointed out that the "package" specifier is horizontal (across the package), but there is no specifier that is just vertical (only subclasses).
Is there anything stopping someone to add a package to a class and compile it? For that matter, they now have access to all the protected members of the package classes.
All classes in the same package :
package KeyLock;
class Lock
public String lockCode = "MySecretKey";
public Lock(String code)
lockCode = code;
protected void tryLock(Key k)
if(k.getCode().equals(lockCode)
System.out.println("Success");
else
System.out.println("Failure");
class Key
protected String Code = "MySecretKey";
public String getCode()
return Code;
public Key()
public class BetterKey extends Key
public BetterKey()
Code = "EvenBetterKey";
class LockPicker
public LockPicker()
Key key1 = new Key();
Key key2 = new BetterKey();
Lock lock = new Lock("UselessLock");
key1.Code = "UselessLock";
key2.Code = "UselessLock";
lock.tryKey(key1);
lock.tryKey(key2);
}Maybe I'm just spun... -

Want to change Public, private and vip address on RAC 10g R2 windows 2003
The network section told us the configuration of the network who support our cluster will have to change all ip address.
We are looking for a complet document who give all the step by step instructions how to make this change.
We have to change the Public, private and VIP at the same time of our 3 nodes cluster.
We know the OCRCFG will be impact. So we will take backup of it first.
Can someone are able to indicate us how to procede to execute this task.
ThanksHi,
i check the Note:283684.1 you give me, but it didn't give all the answers to my problem.
I finally found a recipe to make the job. I would like to tell you it's not supported be Oracle, but it work very well
Don't forget to take a good backup of the ocrcfg and vote disk before you start.
Here we go:
Stop all Oracle service on all nodes before the change of the address, the low format of the ocrcfg and vote disk
change the address in the file host in C:\WINDOWS\system32\drivers\etc with the new address
change the ip address in the window network definition connection with the new address
ocopy \\.\ocrcfg d:\backup\ocrcfg.dmp
ocopy \\.\votedsk1 d:\backup\votedsk1.dmp
rem go to directory of the cluster binary crs\bin
cd /D D:\Oracle\Ora10g\crs/bin

rem example for 2 node
crssetup.exe config -nn host_name_node_1 ,1,host_name_node_2,2 -pn host_name_node_1-priv,1,host_name_node_2-priv,2 -ch D:\Oracle\Ora10g\crs -oh D:\Oracle\Ora10g\crs -c crs_lab -l "CANADIAN FRENCH_CANADA.WE8MSWIN1252"; -q "\\.\votedsk1"
rem ensures that all nodes are configured with the same port for the ONS
racgons.exe add_config host_name_node_1:6200 host_name_node_2:6200
rem oifcfg to direct components to use specific network interfaces
oifcfg.exe setif -global "Public"/10.200.5.0:public "Prive"/192.169.255.0:cluster_interconnect
rem to rebuild the vip address vipca in wondow componant and make the incription in the cluster (in prompt mode or online)
rem at the same time it will create the gsd and ons service
vipca.bat -silent -nodelist "host_name_node_1,host_name_node_2" -nodevips "host_name_node_1/host_name_node_1-vip/255.255.255.0/Public,host_name_node_2/host_name_node_2-vip/255.255.255.0/Public";

I have time capsule and I am unable to connect to the internet using static public IP
I have been using my Time Capsule on my company network for some time.
Recently I removed the time capsule and connected the TC Wan port directly to the firewall. We have got block of static IPs provided to us from our ISP.
Im confused in filling up the internet tap on the Airport Utility (Lion Version)
If Im using a static public IP to connect to the internet should I use
Static, DHCP or PPoe?
IP Address: is this the IP address of the public IP address given to Us from ISP?
Subnetmask. ..no problem
Router Address: what should I type here: IP address of my firewall or my ISP's GateWay IP?
DNS servrs are clear...
Please guide me.Normally you would just set this up with dhcp to the firewall.. if the firewall is setup correctly it will simply pass you one of the block of static IP addresses.. if it doesn't or get a NAT address you should be able to allocate a static IP to the TC in the firewall to its MAC address.
I am not sure that the static IP will work if you just type it in.
If you want to have a go..
If Im using a static public IP to connect to the internet should I use
Static, DHCP or PPoe?
Try static only if dhcp doesn't work because the firewall is not setup.
IP Address: is this the IP address of the public IP address given to Us from ISP?
Yes, a free IP from the block.
Router Address: what should I type here: IP address of my firewall or my ISP's GateWay IP?
Either should work if the firewall is setup correctly.. otherwise just try ISP gateway. -
Is a Public/Private Key Pair possible in SAP?
I have a web service that I would like to run as part of a nightly script. I currently use username/password authentication, but it is not acceptable to have them hard coded, due to Sarbanes-Oxley rules. SAP's site claims to support authentication with x.509 certificates, but is unclear on the implementation details. How could I go about setting up and using a public/private key pair in SAP?
Not really a portal question, and maybe you'll get a better result in a security forum...
However, briefly, yes, the AS Java supports X509 certificates as an authentication mechansm. You need to use Visual Admin to generate a server side certificate, then you need the client side to register its own X509 certificate and then in the Java user admin you need to associate the client certificate with a known user. Now when the client executes the web service call it can pass the certificate and the AS Java will back translate the certificate to a real username. -
How to create a private/public keys?
FredHi Fred,
Following are the steps required are to create a Public/Private Keys:
1. Load the security provider (if not configured in $JAVAHOME/jre/lib/security/java.security)
2. Obtain a handle to a secure random number generator.
3. Obtain a handle to KeyPairGenerator for a specific public key algorithm.
4. Generate the public/private key pair
5. Extract the public and private keys
The following example shows how to generate public and private keys using the KeyPairGenerator and KeyPair interfaces using JCSI's security provider.
import java.security.*;
// Load JCSI's JCA security provider
Security.addProvider(new com.dstc.security.provider.DSTC());
// Seed random number generator using the default seeding
// "SHA1PRNG" = SHA1 Pseudo-random number generator
SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
// Initialise KeyPairGenerator to create 1024-bit RSA keys.
// PK Algorithm = "RSA", Security Provider = "DSTC" (Wedgetail)
KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA", "DSTC");
keyGen.initialize(1024, random);
// Generate RSA pulic/private key pair
KeyPair keyPair = keyGen.genKeyPair();
// Extract public and private keys
PrivateKey privKey = keyPair.getPrivate();
PublicKey pubKey = keyPair.getPublic();
Hope this will help you.

What is the difference of public-read and public-read protected
I have noticed that the access of some variables in API document is public-read protected. I tried the following code. They seem all the same.
class FatherClass{
public-read var a;
public-read protected var b;
init{
a=1;
println(a);
b=1;
println(b);
class SubClass extends FatherClass{
init{
a=4;
println(a);
b=4;
println(b);
var subClass=SubClass{};As you see in my code, subclass can write the variable with either public-read and public-read protected. What write access do the public-read protected widen? That's because your subclass is in the same script as the variable. Move the subclass to a separate script and it would not be able to write when the access is public-read.
"public-read" = any code can read, code in the same script can write.
"public-read protected" = any code can read, code in the same script, in the same package or in a subclass can write. -

Without trying to insult your programming ability, these things
come to mind:
- Omit the slash at the end of "-d docs/" This causes the
message "Generating docs/\constant-values.html.
I'm not sure why the bat file uses a forward slash on
a Windows system.
- Make sure you cd to the directory containing the bat file before
running it.
- Java is case-sensitive (I notice you spelled the filename
both uppercase and lowercase.) Make sure the file name,
the class name in the class, and the class name in the bat
file have the same case.
As far as doccheck not running, we have not yet released the
version that runs on 1.4.x. Please write to "doccheck-feedback"
with "@sun.com" for more info. (I've broken up the email address
so text crawlers won't get it.)
