Virtual Server DB Connection

Guys, I've posted my problem with the logging on the virtual server. I have another problem as well. I created a JDBC connection on the virtual server. But, it does not write the information into the database
This is the same WAR file that I deployed on the default server and it runs well. Meaning, it is able to store the information using the JDBC. Both of the WAR file are same.
Please assist me. Thanks a lot!

Hi,
try to start services with database user.
have you check this?:
ORA-12547: TNS:lost contact

RDP to virtual server stops connecting

I have a Windows Server 2008 R2 Hyper-V host running a number of virtual Windows 2008 R2 virtual servers. I use RDP to remote in to manage the host and guest servers. On occasion, I find I cannot RDP into one of my virtual servers. I enter
the login credentials but the connecting dialog stays on screen and I do not connect.
I then RDP into the host and use Hyper-V Manager to view my running servers. I see that the server I cannot get into is running at 5-6%. Something is running on the server, apparently taking up resources and not allowing me to get in. I
also cannot get in from the Hyper-V Manager. I must reset this virtual server to gain access again. This happens once or twice a month. By the way, other users are still able to run apps from this server and it is pingable.
Can any one offer suggestions on what to look for, how to resolve this?
Thanks

Hi ,
Please check the VM's state in hyper-v manager when it "stopped" .
What is the host's OS ?
What is the guest OS ?
Did you check hyper-v log ( event viewer --> application and services log -->microsoft --> windows -->then check hyper-v logs to find some useful information )
Also please check event log in VM .

Can I install Adobe Connect version 8 on a virtual server?

Hi everyone. We are looking to upgrade our version of Adobe Connect and to put it on a virtual server. Our current enviornment Adobe Connect v8 on a physical server.
Is this possible?
Is it supported?
Has anyone done this and has experienced no problems?
thank you in advance everyone.
scott

Hey Scott,
Many customers today run Adobe Connect 8 virtually on WinSrv 2008 64-bit. First make sure you read the page link below that details our tech specifications and that your server is compliant.
http://www.adobe.com/products/adobeconnect/tech-specs.html
Also, you will want to discuss where your DB will reside (on that same virtual or a separate one). The biggest improvement you will see is with performance. The speed of the server alone is enough to upgrade. Microsoft definitely made some improvements there...
I am assuming you know all the usual WinSrv settings such as Domain, etc...so will not discuss those here..

Scott@Adobe

Connection to a virtual server

Before I start I know this is really a dumb post so if its too dumb just stop reading and go elsewhere.
I am just having a slight issue with connecting my coldfusion server that resides on my virtual server which my local box host.
I will google this but I am really having a real difficult time making a connection.
Thankjs for the time.

Hi,
To allow the Disk Management snap-in to administer Server Core remotely, perform the following steps:
1. Enable the Remote Volume Management rule group in Windows Firewall on your Server Core installation.
2. Start the Virtual Disk Service (VDS) by typing sc start vds at the command prompt.
You can also type: sc config vds start= auto to configure the service to start automatically each time the computer boots.
Then ran the following command on the core server
netsh advfirewall firewall set rule group="Remote Service Management" new enable=yes
--ran the following command on the Win7 machine
cmdkey /add:<Server name> /user:Administrator /pass:<Password>

Need to create a virtual server and give its access to another admin

Dear Sir,
I am a new admin and have 5 Blade server "HP ProLiant BL660c Gen8".
I access these servers through HP enclosure.
I have to install Hyper-V on server 1 which consisted of the OS windows server 2012 R2 Datacenter edition.
I created a plan to create 5 Hyper-V VM's on the physical server and I requested the IT department network Admin that I want these 5 VM's to able to connect to each other.
The network Admin created a Trunking configuration on the physical server and after this setup he provided me Hyper-v node IP address and 5 more IP addresses for the 5 Hyper-v VM's.
Now it was left to me to Add the Hyper-v role and create 5 VM's.
While Adding the Hyper-V role, I was asked in the middle of the setup to add the network adapter for
connecting to external network.
I went inside the network connection settings and I see one network adapter "Microsoft Multiplexer"
which had the IP address of the Hyper-V node which was given to be me by Network Admin.
Besides this I found following Network Adapter: (Mgmt,Trunk):(Mgmt A, Trunk A);(Mgmt B, Trunk B) =Total
6 Network Adapter out of which only "Mgmt" was configured with the IP address of the Hyper-v node given by my Network Admin. Remaining all other Network adapters IPV4 configuration
was unchecked except "Mgmt"
So I selected the "Mgmt" connection while Installing the Hyper-v role
SO I chose this Network connection for adding the Hyper-V role.
My question: Did I chose the correct Network Adapter.
After doing this I created a VM-1 and tried to assign the IP address given by the Network Admin. But the network Admin did not provide me the default gateway so I used the deafult gateway according to the IP address and used the last digit as "1"
like a general installation.
Now my question is: 1.How can I use this VM to be used as a Virtual server?
2. I would like to open this VM through my browser by entering the IP address of this VM-1. How can I do this?
Because I access my physical server through the IP address. SO in the similar way I want to access this VM-1 through the IP address
OR is there any alternate way to access this VM-1 separately.
My Requirement: I need to give VM-1 access to another admin to Install his application on it. SO how to give him to access this VM directly?
This is my main query.
Waiting for your reply.
Thanks & Regards,
Ahmed

Jawin, Jacob, etc.. are fine for creating COM clients but COM servers is a totally different story. I suspect you'll either have to write your own JNI or get out your C/C++ compiler.

Sql server 2000 connect with other than jdbc?

Is there any other way to connect to a Sql Server 2000 database other than with jdbc? My problem actually resides in the fact that I did a small program to test the connection to the database and it works perfectly on my computer but on the server that it's going to stay on, it doesn't.
the program is classic:
try{
     DriverManager.registerDriver(new com.microsoft.jdbc.sqlserver.SQLServerDriver());
     Connection connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://12.345.67.890\ \INSTANCENAME:1433;databaseName=NAME;selectMethod=cursor;","user","pass");
if (connection != null) {
     System.out.println("Successfully connected");
this small program works ok on my computer(win xp, tomcat 6) but on the other computer(ubuntu, tomcat 5.2) says
Exceptionjava.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]The requested instance is either invalid or not running.
I pinged the ip(12.3...) from the server and it works. So I can't figure out what could cause the error. I tried 20 different connection string and don't work. I'm thinking it might have to do with using MS jdbc drivers on a unix platform? or maybe it's from the server firewall(it's a virtual server), anybody can confirm if they had similar problem? Since I can't figure out the problem, I'm trying to test connection using something else than jdbc but google didn't help much
thanks in advance!

I'm thinking it might have to do with using MS jdbc drivers on a unix platform? Why would that matter if you're using type IV 100% Java JDBC drivers?
or maybe it's from the server firewall(it's a virtual server), anybody can confirm if they had similar problem? If you can ping it successfully, how can it be a firewall issue?
You're doing something else wrong.

How to join local computer to virtual server domain ?

Hi everyone,
I am new to Window Azure cloud computing. I found many articles and tutorials available online but I am kind of lost because I don't what I need to do to achieve my scenario.
Scenario: I want to migrate my servers to cloud and retire all local servers such as DC and file server. At the same time, I wish to control the network traffic to limit the clients access to Internet resources. I am not sure retiring the
all local servers is something right to do and how to do.
What I have done:
1. Site-to-Site VPN connection with Dell Sonicwall TZ205 to VNet. (I followed the route-based VPN in this document -> https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CB0QFjAA&url=https%3A%2F%2Fsupport.software.dell.com%2Fdownload%2Fdownloads%3Fid%3D5343958&ei=ykGhVIK6GISWuASU6oHQBw&usg=AFQjCNGGS6fsuK6IHAWyQgZi5fey4xhfKg&bvm=bv.82001339,d.c2E&cad=rja)
2. Created a VM in the VNet. (I can ping the VM from computers connected to TZ205)
3. Installed active directory and configured the domain forest.
What I need to do:
1. How to join the local computers to the virtual server domain controller with S2S and P2S VPN. (Some Internet resources mentioned I need to install Connect agent in order to do this)
Extra questions:
1. Is it possible to request the clients to provide account credentials before the point-to-site VPN to VNet is established ?
2. How do I configure the TZ205 VPN router to send all the Internet traffic to the VNet instead of the ISP gateway? The computers connected to TZ205 firewall router public IP address doesn't change to the VNet gateway IP.
Thanks for your time reading my questions. It will be helpful if you can provide me some useful links or ideas.
Sincerely,
Chee-Kian

Greetings!
I assume there is connectivity between on-prem device and DC on Azure VM.
You can set the Internal IP of the DC as DNS on the on-prem device and trying joining it to the existing domain. Please note to use S2S VPN.
It is not possible to provide user credentials while connecting to vNet via P2S VPN. It's a certificate based authentication (which is so by design).
With regards to your query to send all internet traffic to vNet instead of ISP gateway. Please refer to Forced Tunneling:
http://msdn.microsoft.com/en-us/library/azure/dn835140.aspx
Hope this helps.
Thank you,

Hi Chris,
thanks for your reply! Pilot Extended Listener; Pilot Listener; WWW and JBOSS are running and I started Pilot Extended Listener before Jboss, but it doesn't work.
It tries to open http://localhost/pilot/scriptmain.pw?userinfo=/pilot/pipadmin/adminstart4.htm but there isn't a file "scriptmain.pw" in the pilot directory, only the file "scriptmain.pip". Maybe it is missing?!
best regards,

Getting ipaddress or host name for virtual server

I want to get the ipaddress or host name for virtual server in a cluster environment. If i do
java.net.InetAddress.getLocalHost().getHostName()
it returns the ipaddress of the physical node currently running virtual server.
Is there any way to get the ipaddress or host name for virtual server ?

You can get the hostname by clicking on the account properties in outlook, but the port you connect to must be opened by your system admin.

Virtual server and client command

Hi,
I want to configure firewall load balancing as follows. I have 3 firewalls, FW1, FW2, FW3. I want to create a serverfarm for each FW, i.e. FW1 in SF1, FW2 in SF2, and FW3 in SF3. Then, we'd like to create two Virtual server VS1 and VS2. Each Virtual server has Server Farm SF2 as a backup server farm. I.e. SF1 is the active server farm for VS1, and SF2 is the backup server farm for VS1. We also have SF3 is the active server farm for VS2, and SF2 is the backup server farm for VS3. Note that all connections to VS1 and VS2 will come from the same VLAN (e.g. VLAN X). So the configuration of the virtual server I think should be as follows ;
vserver VS1
virtual 0.0.0.0 0.0.0.0 25
client 192.168.1.0 255.255.255.0
vserver VS2
virtual 0.0.0.0 0.0.0.0 25
client 192.168.2.0 255.255.255.0
So, the question I have is, will this work if we filter who can access the virtual server using the client commmand ? I.e. clients coming from 192.168.1.0 will be using VS1 and clients coming from 192.168.2.0 will be using VS2.
Thanks !

The 'client' command should work as you expect.
You'll need to add the 'serverfarm' command under each vserver. Ex:
serverfarm SF1
real 1.1.1.1
serverfarm SF2
real 2.2.2.2
serverfarm SF3
real 3.3.3.3
vserver VS1
virtual 0.0.0.0 0.0.0.0 tcp 25
serverfarm SF1 backup SF2
client 192.168.1.0 255.255.255.0
vserver VS2
virtual 0.0.0.0 0.0.0.0 tcp 25
serverfarm SF3 backup SF2
client 192.168.2.0 255.255.255.0
I am assuming that you will be using different IP addresses for each vserver. Is that correct?

Business connector server on Virtual Server

Hi,
Currently our 4.6 release Business Connector servers running on Windows NT Operating system. We would like to upgrade them to BC release 4.7 on Windows 2000 operating system on Virtual servers.
Are there any known issues/disadvantages if we install Business connector servers on Virtual Server rather than a Physical server?
These virtual servers will be in the same domain as that of SAP systems. Host names of the upgraded Virtual servers will be same as the current production BC hosts.
Thanks,
Srini

Technical Data
These functions are:
Changed, new, deleted
For Release
   Software Component
·        Component: SAP Business Connector (external)
·        Release: 4.7
Assignment to Application Component
BC-MID-BUS (SAP Business Connector)
Country Setting
Valid for all countries
Use
The following information provides you with an overview of the new features in SAP BC Release 4.7: It also tells you about incompatible changes that you need to know about before performing an upgrade.
SAP BC 4.7 is based on Integration Server 4.6 from webMethods. However, the SAP BC elements in Integration Server 4.6 have been redeveloped (see below for details).
Features
Additional Functions in SAP BC Developer
As well as SAP BC Administrator GUI, you can now use SAP BC Developer to perform typical development tasks. You do not need administrator authorizations in SAP BC Developer to do this. For example, with SAP BC 4.7 you can use SAP Lookup to generate elements for the Developer. This enables you to gather information about function modules, structures (tables), BAPIs and IDocs in an SAP system, and then generate outbound maps or records for these objects directly.
SAP BC Developer contains a new menu, SAP, which contains the following functions:
·        Look up a function module and generate an outbound map
·        Look up a structure definition and generate a record.
·        Lookup a business object.
·        Look up an IDoc and creating a Record.
·        Browser for Function Maps.
In addition, the Developer now also supports the following actions:
·        Generate an SAP inbound map if you want an SAP system to run a service in SAP BC.
·        Generate an SAP outbound map to execute a function module in an SAP system.
·        Generate a record based on an SAP ABAP Dictionary structure.
·        Generate a record based on an SAP IDoc.
SAP BC Developer now also supports a proxy bypass list. This means that you no longer need to define whether a connection runs through a proxy; instead, the bypass list performs this task.
New Public Services on SAP BC Server
pub.string:gzip
Compresses the specified input string and generates a check total (optional). For measurements or for statistical purposes, the lengths of the zipped and unzipped strings are provided as output.
·        pub.string:ungzip
Decompresses a specified input string, which was compressed with pub.string:gzip, and verifies the check total (optional).
·        pub.string:numericParse
Analyzes a number in accordance with a given number pattern.
·        pub.math:randomLong
Generates a pseudo random number and sends its string representation in a pipeline variable. You can use this number as a universal identifier with an acceptable level of security, as long as it is used in non-distributed scenarios and for a small number of variables.
·        pub.file:head
Shows the start of a given file.
·        pub.file:tail
Shows the end of a given file.
·        pub.flow:sleep
Puts the current service into sleep mode for the specified period (in seconds).
Restructuring of the WmPartners Package
The WmPartners package in SAP BC Server has been completely restructured and now offers the following enhancements:
·        Improved status information in the messages displayed in the Transaction Store and the Audit Log. This solves a range of problems, such as incorrect status information being displayed by IDocs.
·        Improved search and sort options for transactions in the file system of the Message Store. In the Transactions menu, SAP BC Administrator GUI offers you a new option, Message Store Query Settings, which enables you to select and delete transactions. In Release 4.7, the Message Store can also be displayed on separate pages, which makes it easier to edit large numbers of transactions.
·        Improved search and sort options for Routing Rules. In the Routing Rules menu, SAP BC Administrator GUI offers you a new option, Routing Rule Filter Settings, which enables you to restrict the number of routing rules that are displayed, and to sort the display. The filter accepts all combinations of characters, and the placeholders '*' (string of characters) and '?' (one character). This makes it easier to sort and search for routing rules, especially if you need to process a large number of communication partners and message types.
·        Forwarding the "Confirm Event" tRFC (triggered by an SAP system) to the next receiver (for the following transports: B2B Service, ALE (R/3 IDoc), and XML (only if another SAP BC is the receiver)) and triggering "Confirm Event" from an external client. Both of these cases can be significant if the final receiver is an SAP system. In this case, "Confirm Event" removes the transaction ID from the ARFCRSTATE table, which can improve system performance significantly when a large number of tRFCs are being processed.
Support for Distributed Statistic Records (DSRs)
SAP BC has supported the generation of DSRs since Release 4.7 DSRs enable you to monitor the performance of each SAP system and its components. In this way, you can check how much system load is produced by each individual component, and how many resources are being used. This enables you to identify "performance leaks" and optimize system performance.
The DSR support integrated in SAP BC also allows you to measure the total retention period of a process in SAP BC. To evaluate the DSRs, you require additional SAP software, including specific versions of the SAP Solution Manager, and the RFC Library. The exact requirements are still being defined.
The details will be published in SAP Note 620418. You can find a link to this SAP Note on the SAP BC download page at http://service.sap.com/sbc-download.
SAP BC Server Core Enhancements
·        Reverse Invoke
The reverse invoke protocol has been enhanced and now allows you to forward more information, such as IP addresses.
If, for example, an application fails because a connection is broken, and other working connections exist, the connection is checked using a ping.
From now on, the internal server can open or reopen a defined number of connections, if necessary.
A document is generated for any exceptions on the internal server.
·        Email Listener
New Features in the Email Listener
¡        Reprocessing of invalid mails for IMAP Server
¡        Processed mails selected as "unread" if they have not been deleted.
You can also specify whether mails with exceptions are deleted or not.
·        Update Manager
The Update Manager manages fixes and patches for the upgrade of an SAP BC Server. Previously , the Update Manager allowed a fix to set other fixes as obsolete, using the updateVoidList field in the update.cnf file of the fix. An obsolete fix is not shown in classpath, but up to now the Update Manager has not been able to give a fix in classpath priority ahead of this other fix. The Update Manager has now been enhanced to support these fix priorities: The update.cnf file in the fix now contains an updatePrecedeList field.
Incompatible Changes
SAP BC Delivery Without JVM
The Windows Version of SAP BC 4.7 is no longer delivered with a Java Virtual Machine (JVM). The SAP BC 4.7 Installation Guide describes the JVMs that are supported.

Deploying application on Virtual Server

I am having a virtual server set up by my department on which i can't install anything. I want to use flash builder for my database project of which I am designing front end in flash builder.
I tried to create same mysql environment on my machine as it is on virtual server. I developed front end which retrieves content from one of the table and display it.
But when I copied the output folder to my virtual server, my application failed with the following error.
Send failed
Channel.Connect.Failed error NetConnection.Call.Failed: HTTP:
I would appreciate any suggestions.

Vijay,
are you using the node manager and starting the server from the admin console?
The node manager starts this as a process and sometimes the process is not getting
killed. try to kill the previously started process and it should work fine

Got an error when install oracle 9i in linux 9 in windows virtual server

Hi Guys,
I am installing an oracle 9i in my laptop that is linux 9 server which is hosted in windows virtual server. when I ran runInstaller, I got an eror that is can't connect x11 windows server using........ When I ran xterm, I got can't open dispaly. xhost + also dosn't work. Is that ok that I can install oracle in a linux that is installed in windows virtual server? What value can I set to DISPLAY value?
Thank in advance.

Linux 9? You mean the one that was end-of-lifed in 2004? (Just checking ...)
If yes, you gotta decide whether it's the 'Linux 9 Boxed Version' or the 'Linux 9 Download Version'. The two have completely different compiler and glibc packages that are incompatible. Fix that incompatibility - relative to Oracle's needs - and you will be able to make Oracle9i limp along.

Migrating a physical database server to a virtual server

we are migrating a physical database server to a virtual server what are the concerns?
the server name and IP address will stay the same

Database server on a virtual server sounds like a bad idea to me.
Databases are huge resource consumers, they require dedicated resources memory/cpu/IO/network.
In virtual settings all this is shared.
So, I predict that in virtual your performance and throughput will suffer greatly.
You can google pro's and con's of virtualized servers for more details.
However, as far as BO product is concerned - all we need is connectivity, if DB connect info doesn't change - we won't see no difference . (except above about performance)

SCSI-3 Persistent Reservation (PGR) on virtual server

I have problem with storage virtualization. It looks, that on virtual server (hosted by Hyper-V) there isn't possibility to have a SCSI Persistent Reservation (PGR). Am I right?
Thank you for any help.

Correct. Use iSCSI, Virtual FC or Shared VHDX (see below).
Guest VM Cluster with Hyper-V
http://technet.microsoft.com/en-us/library/dn440540.aspx
Storage options
The following tables lists the storage types that you can use to provide shared storage for a guest cluster.
Storage Type
Description
Shared virtual hard disk
New in Windows Server 2012 R2, you can configure multiple virtual machines to connect to and use a single virtual hard disk (.vhdx) file. Each virtual machine can access the virtual hard disk just like servers
would connect to the same LUN in a storage area network (SAN). For more information, see Deploy a Guest Cluster Using a Shared Virtual Hard Disk.
Virtual Fibre Channel
Introduced in Windows Server 2012, virtual Fibre Channel enables you to connect virtual machines to LUNs on a Fibre Channel SAN. For more information, see Hyper-V
Virtual Fibre Channel Overview.
iSCSI
The iSCSI initiator inside a virtual machine enables you to connect over the network to an iSCSI target. For more information, see iSCSI
Target Block Storage Overview and the blog post Introduction of iSCSI Target
in Windows Server 2012.
Storage requirements depend on the clustered roles that run on the cluster. Most clustered roles use clustered storage, where the storage is available on any cluster node that runs a clustered
role. Examples of clustered storage include Physical Disk resources and Cluster Shared Volumes (CSV). Some roles do not require storage that is managed by the cluster. For example, you can configure Microsoft SQL Server to use availability groups that replicate
the data between nodes. Other clustered roles may use Server Message Block (SMB) shares or Network File System (NFS) shares as data stores that any cluster node can access.
Hope this helped :)
