Communication between RAC instances

Hi,
I see different answers for this Communication between RAC instances in google.
1. UDP
2.Distributed Lock Manager (DLM)
which one of is correct?

both of them are correct on different layers. The IP protocol used over the interconnect is udp and one of the protocols/mechanism implemented above that is DLM.

Communication between Two WebLogic instances on the same machine

Hi,
We're having a problem with communication between two copies of Weblogic on
the same machine. They are configured with seperate ports (regular and SSL).
Independantly, they run fine. I can access EJBs running on either of them.
The problem is that a bean in one of them has code which attempts to access
an EJB on the other one. The procude fails when trying to obtain the initial
context. This same code works if compilied independantly of WebLogic on the
same machine.
Are there any known issues regards communication between two running
instances of Weblogic on the same machine?
Thanks in advance,

Thanks for the prompt reply.
There is one IP address (internal address 10.227.1.34) one the machine. WLS1
is set up at ports 7001 and 5133. WLS2 is setup at ports 7004 and 7005.
When WLS1 attempts to obtain a context to WLS2 with the URL
t3://10.227.1.34:7004/ it pauses for a long period of time. Running truss
on the both WLS processes shows communication occuring between the two
followed by long periods of silence. Finally WLS2 spits out the error
ConnectionException[7001,7001,5133,5133,7001,7001] (paraphrased, I can get
the entire error if it would help).
After another long pause, WLS1 quits trying with the error 'Server
10.227.1.34:7004 not found' (again paraphrased).
Among the things we've tried:
* Changing the URL from the IP to 127.0.0.1
* Enabling/disabling SSL on either or both WLSs.
* Changing the server name in WLS2's copy of weblogic.properties from
'myserver' to 'myserver2' (previously they were both 'myserver')
* Upgrading WLS2 to 5.1.0sp5 (Tried upgrading WLS1, but was getting class
not found errors and quit because that WLS is being used by other people)
This is a Solaris server. WLS1 is running 5.1.0 and WLS2 is running 5.1.0sp5
Any suggestions would be appreciated.
Best,
Randy Yarger

Communication between two clients

In Java Networking, communication between server-client or bwtween server-multiple clients is general. But How will be the communication between two cients, means two clients can send & receive messages to & from each other(being guided by server).

Sorry,
I didn't get your reply clearly.
I want, if Server is running, and two clients(two instance of a same program) are opened, whatever message(string)client1 send to Server,then the Server needs to send those to client2.Again, the some response should come from client2 to client1 thru Server.
How can I implement this?
If you have idea, or some sample code about this, please let me know.
Regards.

Communication between a driver and application.

Communication between a driver and application.
I am writing a driver for a PCI card. I have found very good examples of how the driver should be build.

Communication between TNS_Listener and Apex Listener

Dear all,
I how does the communication between TNS Listener, Apex Listener, and Apex? For some reason I got the following error from Apex listener:
Caused by: oracle.dbtools.rt.web.WebException: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource
Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptorI truncated some of the Java object messages.
This occurred when I tried to connect to Apex. Then I can fix this by going to:
http://localhost:8080/apex/listenerConfigurethen, everything worked fine.
My listener.ora file:
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
ADR_BASE_LISTENER = /usr/local/oracle
ADR_BASE_ORACLE_LISTENER = /usr/local/oraclemy tnsnames.ora file
INARA =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = inara.snowdrop.com)
)where inara is the instance name and firefly is the hostname.
Does the order of whether starting TNS Listener first or starting Apex Listener first matter?
Best regards,
Val

Hm, I'm not able to reproduce the error. There was one time when I started APEX Listener got:
java.net.BindException: Address already in use: 8080=com.sun.grizzly.http.SelectorThreadHandler@46d999aand when I did the netstat -a got:

There was one time netstat -a showed me this (this happened after I stopped Apex Listener, stopped TNS Listener, shutdown the database, started database, started TNS Listener, and started Apex Listener):

Encrypting communication between an app that uses an ODBC/DSN (with ADODB) and SQL Server 2008 R2

I've been doing a lot of reading the last couple of days on how we can encrypt db communication between our product app and a customer's SQL Server db, but cannot make it work as expected. The app uses a ODBC/DSN to connect to the SQL Server db. I use this
ODBC app to setup the DSN (on a Windows 7 PC):
C:\Windows\SysWOW64\odbcad32.exe
The DSNconnection uses the SQL Server driver 6.01.7601.17514 and has these properties:
- WinNT authentication.
- Client Config button: TCP/IP to <server-name>\<instance.-name>
- Change to default db: <name-of-app-db>
- Everything else is default setting.
SQL Server is on the same Windowns 7 PC and has a self-signed cert installed (used IIS to generate it) and has the Force Enryption set to "yes".
I have a test C# program that uses the ADODB 2.7.0.0 COM-wrapper, made by Visual Studio after adding a reference to the ADO 2.7 library version 6.1.7601.17857. The program creates an ADODB.Connection object that has a simple connection string: "DSN=<san-name>;UID=<user>;PWD=<password>". The
program then creates an ADODB.Recordset object and reads and displays a field from a table.
Works fine.
If I go into SQL Server and set Force Encryption to "no," clear the cert, restart the SQL service, and then re-run the program, it works fine.
Here's the kick. If I go into the DSN and select "Use strong encryption for data" the Test button on the DSN works—why does it work? The SQL Server is no longer encrypting the connection so an error should occur. If I run the test program, it works
as well—why? I can look at the connection properties in the test program and see that ADODB has added the ";Encrypt-yes" stuff to the end of the connection string. Yet that option seems to have no effect.
If I set the SQL instance back to Force Encryption:yes, enable the cert, restart the SQL service, and clear the DSN's "Use strong encryption for data" option, I can still connect to the db with the
test program—why?
What am I doing wrong? I need to be able to ensure that the communication between our app product and the SQL instance is encrypted, and that we get an error if the SQL instance does not support encrypted communications. We really don't want the customer
to have to enable Force Encryption because they have other db's on their SQL Server that do not use encrypted communication, but they want to know that our product's communication channel with the db is encrypted.
No, I can't change the app product's code at this point in time. I'm stuck with working with what a DSN called from ADODB has to offer.
Also, how can I be sure that communications are encrypted? I mean, I've tried things like "SELECT * FROM sys.dm_exec_connections" but that doesn't help because I have no idea how to tie the list of sessions shown back to my test program, although
I guess it's a good thing that some of the sessions listed show encrypt_option as TRUE.
-glenn-

Ah yes, very good point. It's easy to miss because you have to delete then recreate the DSN in order to change drivers. So I switched the DSN over to the SQL Native 11 driver.
Now when I try to connect to the SQL instance as <computer-name>\<instance-name>, and without a cert on the server, I get "the target principal name is incorrect". Perfect; now we're getting somewhere!
Change my DSN to use <fqdn>\<instance-name> and it works. This tells me that SQL Server has auto-generated a cert and named it <fqdn>. I would have expected the "cert fail" error, not a cert
name mismatch, because I'm not using Trust Server Cert.
So I load up my self-signed cert, and that works too.
I am still confused as to why I'm not seeing the "cert fail" error when I have no cert loaded on the SQL Server. I am not using Force Encryption on the server at all, so wouldn't expect SQL Server to auto-create a cert when an Encrypt=yes request comes in,
but apparently it does?
I also ran into a problem with this:
select c.session_id, c.encrypt_option, s.client_interface_name
from sys.dm_exec_connections c
join sys.sysprocesses s
on c.session_id = s.session_id
where s.dbid = db_id('MyDatabase')
There is no s.client_interface_name, probably should be s.hostname. There's also no s.session_id. I thought maybe this should be s.sid, but then no rows ever come back. The c.session_id looks like 51 and 52, but the s.sid looks like a very long binary number,
so these two fields cannot be joined. I don't know how to convert the sid's properly so that the join would work. Ah wait, I just found the s.spid column; the join works when that column is used (I assume that's correct anyhow).
If I add a Thread.Sleep(30 seconds) to my C# program just before the connection is closed, this query shows me the session for the correct hostname has encrypt_option=TRUE.
And I have to keep my fingers crossed that all the app I/O will still work properly after
changing the driver. Probably a safe bet though.
Think I'm ready to throw in the towel on getting the "cert fail/no SSL" error to appear.
It does look like I am able to sufficiently show that the connection is encrypted when Encrypt=yes is used with the newer driver.
Thank for all the help!

Communication between thread in the same process using file interface.

Hi,
I am developing driver and i need to communicate between two thread.
>can anyone guide me on implementing communication between two thread in the same process using File Interface. First thread will be driver and second will be application.I need to send IOCTL like commands using File interface ie is WriteFile(),ReadFile()
from Host process to driver through file-interface(which run's in driver context).Host process should not be blocked for the duration of the driver to process the command.
>File-interface will run in driver context and it will be responsible to receive command from application and pass it to the driver.
what are the complexity introduced?
>Can anyone also give me the link/reference to get more information on this topic?
>How to replace IOCTL command's for instance baud _rate change command with a file interface for example with IRP.

Here is the detailed query:
Hardware Abstraction Layer will interact with Driver(Both will be running in complete different process) .there is a IOCTL for command and File interface for read and write.
My requirement is:
Both should run in the same process so HAL will run as one thread and driver as another thread in the same process .I don't want HAL to wait for completion of request and also i don't want driver to be blocked .
We are planning to use a File Interface for communication between Hardware abstraction layer and Driver
HAL will send the command or read/write operation to a file interface and driver will get the command or read/write request from the File interface
There is a flexibility to change Hardware Abstraction layer and also the Driver
Is it possible to use IOCTL between two thread under same process? if not what other options do we have.
Can we use File interface to send command (like IOCTL) between two thread?

Data conversion for communication between Java and C/C++ program

The real problem, i guess, is about data type conversion between Java and C programs. For instance, and int is supposed to be 4 bytes in Java, and also in C/C++. But, as far as I know, the size of and int in C depends on the processors architecture, so if it were a 64 bit arch., size of and int, double, etc. in C, would change. The real scenario would be a communication between a 32 bit machine (Java) and a 64 bit machine (C/C++).
First of all, is this assumption correct?
If so,
how is it possible to deal with this problem in Java?
Is there any way to know 'type length' automatically? or
would it be necessary to modify the Java program to work with a C program in 32-bit or 64-bit arch?
thx in advance

Yes you should develop the C part of the protocol first and then build from there.
See http://forum.java.sun.com/thread.jspa?threadID=5243547 for a previous discussion of this topic.
I understand what you mean, also the topic you referenced. I will explain the situation a bit more. The protocol is already defined: (16 bits message size, 16 message id, 32 bit time, etc.); it is also defined in C (structures and so on). So it would be easy to write my Java code using the specified protocol in bytes, and C types wouldn't be necessary to be considered. But, let's say that the C code can't be modified, and I thought (and don't know yet if its correct), that size of C types CAN changed depending on architecture. So if size changes for C types (code is specified in short, int, etc, and not in bit format), it all would be a mess, if I don't implement something in my Java code.

I don't believe that 32 or 64 bit enters the equation here at all.Maybe 32 o 64 doesn't mind, but sparc or PC could take a point here. Communication would be between a sun solaris sparc and windows x86 PC. But if type size in C/C++ does not change, I wouldn't really have any problem then...
The situation is not ideal, I know, but is what I have; and I think I could have problems if I run the C program in other machines; so I would have to try to solve it whithin my Java Program.
I hope it is clear now what I need.

Synchronous Communication between two Decoupled Orchestration

Hi All,
Is there a way I can achieve synchronous communication between 2 orchestrations (decoupled orchestrations) where I need to pass multiple parameters from calling orchestration to called orchestration.
Thanks,
Sumit
Sumit Verma - MCTS BizTalk 2006/2010 - Please indicate "Mark as Answer" or "Mark as Helpful" if this post has answered the question

Hi Sumit,
if you have hundreds of orchestration means lot of small small business processes which are tightly coupled...
It is better to publish process / orchestration as service so it will SOA base ..it will work isolate. but remember if you publish more web base service. it will be burden on IIS. we have only one Host instance to handle..we can't create more host
instance to handle like in-process host in one server..we have to go for cluster environment..so first approach will be window base service (if possible achieve business process ) to handle by in-process host instance.
If you have many small small services then we need one master service to watch/process all the services.
Exmaple...
Like one process A, need to execute five small services/processes a1,b1,a2,c1,c3
and Process B need to execute four small services/processes b1,b2,a1,c1
You have to go for canonical schema and master entry table where you can dynamically change or attached or remove small service.
Regards
Suman

Rac Instance Crashes

Thanks for reply,
My redo logs size is default 50mb.There is currently no load on the system since we are not using this environment for time being.The log switches are averaged to be 8 per day.I think Increasing the size of redo will further cause the problems since the archiver may again hold lock for more time.
Since there is no dedicated connection between the nodes and storage ,So increasing the hardware and network configuration is only solution to this? Or I am still missing something...
As far as configuration is considered i cannot add more resources to this environment.How can I solve this issue?

How to determine which RAC-instance the appl. is logged onto?

Dear all,
I need to have my application server determine which RAC-
instance is currently active (logged onto). I have a
tnsnames.ora file with a primary-, and secondary RAC-
instance configured, and Failover/Failback between the
instances work fine. However, I would be interested in
determining which instance I am curently using.
Does the Oracle Net Protocol have support for letting me
"read" this out, or...?
Thanks.
Regards, Eldor R.

Thank you for the prompt reply.
Is there, in the Oracle Net Protocol, available
function(s) for reading out this information
directly without "parsing" the trace file?
I would like to read out this information from my
application run-time.
Thanks.

New RAC Instance 10.2.0.2 - won't start

Hi There,
I am not a DBA, though have a good understanding of UNIX. For a work project I need to create a RAC instance on Solaris 10 x86 u6... I have installed the software, created the instance using DBCA, but unfortunatley it will not start.
I am recieving the following errors when i run the command below to start the instance:
bash-3.00$ srvctl start instance -d orcldb -i orcldb1
PRKP-1001 : Error starting instance orcldb1 on node sol002
CRS-0215: Could not start resource 'ora.orcldb.orcldb1.inst'.

I have the following projects defined for oracle on both nodes in the cluster.

After trying to tweak these values between 700mb and 4gb (i only have 1500mb of RAM) i added some values into the /etc/system (which i understand to be depricated on solaris 10) as reccomended in the post below due to bug 5340239 on Metalink, but still did not resolve the problem.
http://posulliv.com/?cat=12
When using DBCA to create the database, I specified to use 40% of available system memory. I am not sure where those values get defined and if that may also be playing a part in this issue.
Any help wuld be greatly appreciated.

bash-3.00$ srvctl start instance -d orcldb -i orcldb1
PRKP-1001 : Error starting instance orcldb1 on node sol002
CRS-0215: Could not start resource 'ora.orcldb.orcldb1.inst'.Please check imon* file at $ORACLE_HOME/log/<nodename>/racg/
Or check by debug
$ export SRVM_TRACE=TRUE
$ srvctl start instance -d orcldb -i orcldb1
Show us about your error....
if you have the problem about project
Can you make project for the "system" ?*
by memory for "system" > "oracle" ("system" can more physical memory)*
and try start instance again ;)

Rconfig: converting a single instance to RAC instance

Hi,
I am trying to use the "rconfig" utility to convert a single instance to a RAC instance in an existing RAC cluster.
I have modified the .xml file, and am trying to run the conversion from the 1st node in the 2 node cluster (where the single instance resides).
The only error message i seem to be getting is below:
<Response>
<Result code="1" >
Operation Failed
</Result>
<ErrorDetails>
ORCL_DATA_ORCLCLN The specified diskgroup is not mounted.
</ErrorDetails>
</Response>
</Convert>
</ConvertToRAC></RConfig>
Now I dont really understand why I would be getting that message as the instance is up and running and ASM disk group is mounted on node1 at the time i run the rconfig command, though its not clear to me if I also need to somehow mount the ASM disk group on the second node prior to running the rconfig command??
node1:
bash-3.00$ asmcmd -p
ASMCMD [+] > lsdg
State Type Rebal Unbal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Name
MOUNTED EXTERN N N 512 4096 1048576 10181 7442 0 7442 0 ORCL_DATA_ORCLCLN/
node2:
ASMCMD [+] > lsdg
State Type Rebal Unbal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Name
I have attached the output of the alert log during the rconfig conversion of the target database, but it all looks pretty standard to me (keep in mind i am an oracle novice!).

Ok,
So I managed to get the disk group mounted on the second node, and re-ran the rconfig process.
I got a little further, but encountered another error which is displayed below:
-bash-3.00$ rconfig racconv.xml
<?xml version="1.0" ?>
<RConfig>
<ConvertToRAC>
<Convert>
<Response>
<Result code="1" >
Operation Failed
</Result>
<ErrorDetails>
/u01/app/oracle/product/10.2.0/db_1/dbs Data File is not shared across all nodes in the cluster
</ErrorDetails>
</Response>
</Convert>
</ConvertToRAC></RConfig>
I am not using a shared oracle home, each node in the cluster has its own oracle installation residing on local disk. Is a shared oracle home a pre-requisite for usin rconfig?
I have provided the .xml file I am using below:
-bash-3.00$ cat racconv.xml
<?xml version="1.0" encoding="UTF-8"?>
