How run Dbconsole on two servers ?

Hi,
I would like to know how run dbconsole on my 2 servers Grid. Today only one server run dbconsole.
Thanks,
Guillaume R

Hi
It is only running on node1 or Node2 ,but not both if them at the same time :)
cd $ORACLE_HOME /bin
then
emctl start dbconsole
emctl status dbconsole

How to connect to two servers behind a firewall

Let's say I have a LAN with two independant servers, one at 192.168.2.10 and one at 192.168.2.20
As it is now, I can fwd the 548 port to one server and it works.
Is there a way i could connect to both servers, maybe having one and port 548 and one at 549, so if I connect using the default address, it will connect to server A and to the adress plus the port :549 it will connect to server B
I tried forwarding port 548 to one server and port 549 but for now, my router/firewall complains that I have a port conflict.
What's the simplest way to achieve what I would like.

Oh man, I think I've seen the answer to that in these treads, but it'd be around 20-30 pages back... iirc it would involve editing Hosts' or hppd file... BIG Help I know... but perhaps a real expert will be along shortly!

How to set up NAT for two servers using same port with ASDM ASA 5505

Hi there,
We have a new installation of a ASA 5505 and are trying to get some NAT issues straightened out. Here is the scenario: On our internal network, we have two servers running Filemaker Server, a relational database server that clients connect with using port 5003. Our goal is to be able to allow users from the outside to access either of these servers as needed. I know how to set up a simple static NAT rule and matching Access rule in ASDM which would be fine for a case in which only one server using a given port is running on a network, but for simple static rules I seem to be blocked from entering a different translated port number from the orginal port number, which becomes a problem when two servers we need to access from the outside are running software using the same port number.
What is the simplest way to address this need? I am guessing that I need to set up a scenario like this, where port 5004 (or any arbitrarily choosen unused port, can be used to access the second server:
Outside user enters FQDN:5004 and this translates to Database server # 1 as 192.168.1.40:5003
and
Outside user enters FQDN:5003 and this translates to Database server # 1 as 192.168.1.38:5003
If so, what is the easist way to get this done? Or is there a better what to handle this scenario?
Thanks in advance,
James

I would create two objects and use object NAT
object network Obj_5004
host 192.168.1.40
object network Obj_5004
nat (inside,outside) static service tcp 5003 5004
object network Obj_5003
host 192.168.1.38
object network Obj_5003
nat (inside,outside) static service tcp 5003 5003
Of course you will need to open your outside interface for tcp ports 5003 and 5004 to make this happen

Singletons running on two servers at the same time

Hello,
          we faced one interesting situation with our application, running on clustered BEA Weblogic 9.2. We implemented some Singletons (ie. Singleton Service in a Weblogic cluster) and they are running fine. Most of the time.
          Common scenarios: cluster is started -> the singletons run on one server; the server is brought down -> the singletons are started on the second server.
          However, we had recently two situations where the Singletons started on both servers! Here they are:
          1) We use Database Migration Basis and we have a dedicated table for Weblogic to capture current state of the singletons. Due to the fact that database (Oracle RAC) was partially available one of the Managed Server could not get the lease and probably assumed that no singleton is running, therefore started the singletons locally.
          2) Network outage: we had several minutes where none of our servers could communicate between them (neither between SASU MS nor with the database). Consequence: each MS decided to start the singleton locally (after some time, which I assume is the waiting time). Once the network came back the servers could communicate again but the duplicate singletons are not deactivate, so they are running in parallel.
          Anyone experienced the same or similar issues? How to prevent the above? Is the Consensus Migration Basis a better choice? (I think yes for #1 but not for situation #2).
          Any helpful answer is appreciated.
          Thank you, best regards,
          Remus.

In general its not a good idea. Running PSConfig will try to establish a lock on the configuration database. Doing that from two servers at the same time may cause the update to fail.

How to split mailservices among two servers (no xsan yet)

How can I split the load on our mailserver (getting rid of the daily VM growth and potential crashes / down time) by using TWO servers as opposed to one?
Apparently the root of the cause is too many imapd connections and DirectoryServices then gets in to problems stalling the whole server (EG see my latest 3-4 posts)
SMTP out of the house should not pose a problem, and access for the end users to the (manually moved) imap data location should be handled easily after pointing the users to the second mailserver in WGM.
BUT incoming mail makes me unsure - port 25 can only be pointed to one server on the LAN (naturally , so how do I configure the ("primary") mailserver to make sure that the local mail-delivery (for the users that use the second mailserver) will actually be sent to this second server.
I would think that this should be easily possible - somehow - and that the LMTP service will be the part responsible for this change.
PS.: I still cannot understand why a dual 2 GHz intel server is unable to perform satisfactory - with 10.5.6 server - serving the small amount of IMAP users we have, ca. 250 users.
Currently ps ax | grep imapd | wc -l tells me that I have up to ca. 150 connections when the VM growth warnings starts to show up in the system.log

The server is still pretty much having the default setup, though I have implemented Pterobytes "Frontline Spam Defense", but:
A. I have incresed the number of processes as per an Apple article for "heavily loaded servers":
cat /etc/launchd.conf
limit maxproc 1000 2000
B. I have changed /ets/cyrus.conf
IMAP increased to 5
LMTPUNIX increased to 2
<pre> imap cmd="imapd" listen="imap" prefork=5
imaps cmd="imapd -s" listen="imaps" prefork=0
lmtpunix cmd="lmtpd" listen="/Volumes/Bric-RAID-03-up/Mail/imap/socket/lmtp" prefork=2</pre>
I got this advise from Pterobyte a year ago when I had problems with the performance of the old mailserver (the hw was a G4, the hint helped a lot!)
The timeout you refer to is not set in the config file (also not in a fresh in stall of 10.5.6), it's only listed (as 30) in /etc/imapd.conf.default.
But I presume that if the parameter is not set in my cinf file, then the default files settings are in effect(?)
I was thinking of changing this value just yesterday, but after reading the man imapd.conf I thought that it would not make any diference, since 30 is "the minimum":
timeout: 30
The length of the IMAP server's inactivity autologout timer, in minutes. The
minimum value is 30, the default.
I guess I have to make this chang anyway
The server is a dual 2 GHz intel with 5 GB ram (and still 4 vacant slots).
Today's top output looks like this (the server was rebooted 24 hours ago!)
Mail spool (currently ca. 120 GB) is on an RAID-5 xraid
<pre>Processes: 171 total, 2 running, 169 sleeping... 741 threads 10:57:37

I have been running Apples top-guide.pl script for a couple of days to monitor the servers "health" in general as well as I am logging the number of imapd connections every minute.
I dont find the numbers alarming.
During the max load yesterday (between 12.10-12.48) there was a peak of 210 imapd connection (users coming back from lunch and checking mail?).

How to Break the cluster between Two servers

Hi Experts,
Since Iu2019m new to BOBJ XI R2.I would like to know how to break the cluster between two servers.
Description :
So far we took the copy of QAS Server1 to the new QAS server2 (Through Mirroring Tool ). Now those two servers are cluster together, I can see QAS server1 CMS Name, Cluster Name, cluster member name in QAS Server2 (CMC-> Setting -> Cluster).
Besides in QAS Server1 CMS Name and Cluster name are pointing to the QAS Server1, except Cluster Member (This is still have two members Server1 and Server2).(CMC-> Setting -> Cluster).
In QAS Server1 and QAS Server2 (CMS-> Servers), I can able see both server name under Machine Name tab.
I would like to make those two servers as independent servers. There are two different data source for those two servers. I want to remove the cluster in both servers.
Right now QAS Server1 is running and QAS Server2 is stopped.
If i create/modify a group under new Mapped NT Member Groups in QAS server2 ,it is getting reflecting in QAS server 1.
Could you please tell me the steps to resolve this problem.
BO Version: BO XI R2
Regards,
Sridharan

Hi,
Maybe the external CMS is still 'attached' to your SIA node. Please go to the CCM (Central Configuration Manager) and stop the SIA (Server Intelligent Agent). On one of the tabs you can see if there is an external CMS part of your environment. Delete it and restart the SIA. Retry if you can delete the services now from within your CMS. It may well be that you have to stop both environments and delete each others CMS via the CCM to get it working. If you have not changed any permissions for your Administrator account the security model will not be the one causing this.
Hope this helps...

Thanks for your help Brij011 - much appreciated. Apologies as I'm a newbie but I've looked at the info for synching and I appear to have all the switches flicked on my iPad. Does the iPad and iBooks only sync in iCloud for purchases as I appear to be doing something wrong. I could sync ok when books was in iTunes but since migrating to Mavericks I think I'm doing something wrong!!

How Can i Use two Different Public IP Addresses no my DMZ with ASA Firewall.

How To Using Two Different Public IP Address on My DMZ with ASA 5520
Postado por jorge decimo decimo em 28/Jan/2013 5:51:28
Hi everyone out there.
can any one please help me regarding this situation that im looking for a solution
My old range of public ip address are finished, i mean (the 41.x.x.0 range)
So now i still need to have in my DMZ another two servers that will bring some new services.
Remember that those two server, will need to be accessable both from inside and from outside users (Internet users) as well.
So as i said, my old range of public ip address is finished and we asked the ISP to gives some additional public
ip address to address the need of the two new servers on DMZ. and the ISP gave us the range of 197.216.1.24/29
So my quation is, on reall time world (on the equipment) how can i Use two different public ip address on the same DMZ
on Cisco ASA 5520 v8??
How my configuration should look like?
I was told about implementing static nat with Sub Interfaces on both Router and ASA interface
Can someone please do give me a help with a practical config sample please. i can as well be reached at [email protected]
attached is my network diagram for a better understanding
I thank every body in advance
Jorge

Hi,
So looking at your picture you have the original public IP address range configured on the OUTSIDE and its used for NAT for different servers behind the ASA firewall.
Now you have gotten a new public IP address range from the ISP and want to get it into use.
How do you want to use this IP address range? You want to configure the public IP addresses directly on the servers or NAT them at the ASA and have private IP addresses on the actual servers (like it seems to be for the current server)?
To get the routing working naturally the only thing needed between your Router and Firewall would be to have a static route for the new public network range pointing towards your ASA OUTSIDE IP address. The routing between your Router and the ISP core could either be handled with Static Routing or Dynamic Routing.
So you dont really need to change the interface configuration between the Router and ASA at all. You just need a Static route pointing the new public IP address towards the ASA outside IP address.
Now when the routing is handled between the ISP - ISP/Your Router - Your Firewall, you can then consider how to use those IP addresses.
Do you want to use the public IP addresses DIRECTLY on the HOSTS behind the firewall?This would require you to either configure a new physical interface with the new public IP address range OR create a new subinterface with the new public IP addresses range AND then configure the LAN devices correspondingly to the chosen method on the firewall
Do you want to use the public IP addresses DIRECLTY on the ASA OUTSIDE as NAT IP addresses?This would require for you to only start configuring Static NAT for the new servers between the inside/dmz and outside interface of the ASA. The format would be no different from the previous NAT configuration other than for the different IP addresses ofcourse
Of the above ways
The first way is good because the actual hosts will have the public IP addresses. Therefore you wont run into problems with DNS when the LAN users are trying to access the server.
The second way is the one requiring the least amount of configurations/changes on the ASA. In this case though you might run into problem with DNS (to which I refer above) as the server actually has a private IP address but the public DNS might reply to the LAN hosts with a public IP address and therefore connections from LAN could fail. This is because LAN users cant connect to the servers OUTSIDE NAT IP address (unless you NAT the server to public IP address towards LAN also)
Hopefully the above was helpfull. Naturally ask more specific questions and I'll answer them. Hopefully I didnt miss something. But please ask more
I'm currently at Cisco Live! 2013 London so in the "worst case" I might be able to answer on the weekend at earliest.

One client and two servers

hi,
how a client can communicate to two servers by socket connection (parallel) ?
here is my code, when i run one server at a time it works but if i run both server programs and then the client i dont get any exception and it does not get my data from servers it generates "press any key to continue..."
server 1 --------------
public static void main(String[] args)
ServerOne so = new ServerOne(7500);
so.accept();
public void accept(){
try{
System.out.println("Server");
Socket s;
while(true)
s = sock.accept();
}catch()...
server 2 -----
exact like server 1
klient---------------------------
public static void main(String[] args)
try{
System.out.println("Client");
MyThread MT = new MyThread();
MT.startThread();
Socket s = new Socket("127.0.0.1",7500);
InputStream is = s.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is));
while(in.ready())
String str = in.readLine();
System.out.println(str);
s.close();
}catch(IOException e){e.printStackTrace();}
mythread --------------------
public void run()
? try
Socket s = new Socket("127.0.0.1",1234);
InputStream is = s.getInputStream();
BufferedReader in= new BufferedReader(new InputStreamReader(is));
while(in.ready())
String str = in.readLine();
System.out.println(str);
s.close();

You cannot run two servers on exactly the same socket. Are you aware of this?
At least the port number has to be different.
// Server 1:
try {
    serverSocket = new ServerSocket(4444);
} catch (IOException e) {
    System.out.println("Could not listen on port: 4444");
    System.exit(-1);
Socket clientSocket = null;
try {
    clientSocket = serverSocket.accept();
} catch (IOException e) {
    System.out.println("Accept failed: 4444");
    System.exit(-1);
// now the connection is established
// do the same for the other server, but for another port
// The client has to explicitly call each Server, to establish each connection.

Two servers (serverSocket) behind the SAME firewal !?l

Hello !
I dont know if this is the right forum for this qusetion,
and maybe the question is really stupid, but ...
I made a little client/server application, just to
play around with sockets and serverSockets.
It works fine, but now i ask myself:
What happens, if there are two of my servers running on two
different computers in the SAME LAN behind the SAME
firewall/internetgateway, and both are listening on the SAME
port ?
F.e. if the extern IP of this LAN/(its gateway) is
204.556.234.123, and a client in the internet is connecting
to it on the port, on which the two servers behind the firewall
are listening, WHO'S ANSWERING ?
(If this port is set to "open and forward" in the firewall)
The one with the shorter patch-cable ? ;)
How is it possible for the client to differenciate
this two servers in that LAN?
The only logical solution i found is that this two servers
have to listen on different ports,
but i think there has to be another explanation and/or solution.
Do i have to take care about situations like that in my
server-application ?
I have the feeling that i have to...somehow.
OK, you see i dont know much about this...
i would be very thankful for every hint and explanation.
Thank you very much,
greetings,
huni.

(If this port is set to "open and forward" in the

The two computers running your server have unique addresses on the internal network. The firewall will forward incoming connections to one of those addresses. Maybe it can do some simple "load balancing" by forwarding some connections to one server and some to the other, but still, any particular connection will only go to one server.

Monitoring two servers with same IIS configuration using SCOM

Hello,
We have two servers which has the same IIS configuration including sites names, how do we configure APM to monitor and get events captured on two different monitors on SCOM 2012 R2.
Thank you, Anand
Anand Franklin

Hi Anand,
There is no problem at all, if applications IIS paths (Web Site names + Web application name in IIS) absolutely match. Make sure both servers have SCOM Agent installed and connected to the same Management Group.
In .NET Application Performance Monitoring template just keep Target Group field blank (it's blank by default) - that will mean the application will be monitored on each server within Management Group where it's discovered. The same configuration of
APM monitoring will be used for all app instances.
If you want to monitor the app only on two servers, and at the same time the app is hosted on more than these two boxes, you can create Windows Computer group populated with appropriate servers and specify this group as Target for APM monitoring.
If you want to differentiate APM configuration for specific app instances, you should create several Windows Computer groups and bind each group with separate configuration - in this case you will have to run .NET Application Monitoring template several
times, picking up the same app, but changing APM settings and setting new Target Group.

How to start 2 RMI servers on same machine ??

Hello friends,
I am developing databackup project USING RMI
i want to start servers on same machine and client may be on different machine.
we tried it used as on different port . but it stil not working.
so can u provide me solution for that ,
how to start that two server on the same machine. ?
reply me soon
thanks

Ghanshyam,
It is possible to run multiple RMI servers as long as the port is different. For instance if you run the RMI daemon using port 2700:
rmid -port 2700and RMI daemon using port 2800:
rmid -port 2800You will see these ports open if you do an nmap or netstat -aMake sure you bind your separate RMI instances on separate ports when calling Naming.bind()Anthony
