I agree with Rafi, you need to have your company set up a vpn-endpoint at the office, and then, using a vpn-client on your home machine, you'll be able to run your applications from home.
A second alternative is connecting a tunnel over ssh to a server at the office, and then send the application traffic through that.
It's wery hard for us to give you any good suggestions without knowing the details of your network, so I suggest that you talk to the IT/IS-dept at your workplace, so that they can help you with this problem.

What is the OS version of the PC you are running and is it physical machine or virtual machine that is running the HRC client ..
OS Version Windows 7 Home Premium 64 bit and it’s a physical machine.
. The Max DB Connections for Report Client Sessions is set to 5 for each servers (There are two servers). The no of HR Sessions is set to 10.
I wanted to know if there is a way to find the HRC sessions active now and terminate the one or more or all of that sessions from the server end ?

We have had this "PRX5" problem with Exchange 2013 since the RTM version. We recently applied CU3, and it did not correct the problem. We have seen this problem on every Exchange 2013 we manage. They are all installations where all roles
are installed on the same Windows server, and in our case, they are all Windows virtual machines using Windows 2012 Hyper-V.
We have tried all the "this fixed it for me" solutions regarding DNS, network cards, host file entries and so forth. None of those "solutions" made any difference whatsoever. The occurrence of the temporary error PRX5 seems totally random.
About 2 out of 20 incoming mail test by Microsoft Connectivity Analyzer fail with this PRX5 error.
Most people don't ever notice the issue because remote mail servers retry the connection later. However, telephone voice mail systems that forward voice message files to email, or other such applications such as your scanner, often don't retry and
simply fail. Our phone system actually disables all further attempts to send voice mail to a particular user if the PRX5 error is returned when the email is sent by the phone system.
Is Microsoft totally oblivious to this problem?
PRX5 is a serious issue that needs an Exchange team resolution, or at least an acknowledgement that the problem actually does exist and has negative consequences for proper mail flow.

How to Configure Remote Connections To SQL Server 2008 R2 Express

Post written June 10, 2010 and pertains to:
SQL Server 2008 R2 Express on both my server and local machines: SQLX_SRV,
SQLX_LOC
SQL Server 2008 R2 Management Studio on both my server and local machines:
MS_SRV, MS_LOC
Windows Server 2008 R2 Enterprise installed on a Hyper-V VPS: WS
SQL Server Configuration Manager on both my server and local machines:
CMGR_SRV, CMGR_LOC
Server Manager: SMGR
I am connecting to my hosting server via Remote Desktop Connection: RDC
I installed SQLX_SRV and MS_SRV on my hosting server and SQLX_LOC and MS_LOC on my local development machine. I am able to use MS_LOC to connect to SQLX_LOC and to use MS_SRV to connect to SQLX_SRV. However I am not able to use MS_LOC to connect
with SQLX_SRV. Here's what I have done so far:
SMGR -> Configuration -> Windows Firewall to turn off the Windows Firewall for Domain, Private and Public profiles. Obviously I'll change this later, but until I can connect I want to remove as many variables as possible.
CMGR_SRV -> SQL Server Services to confirm that both SQL Server (SQLEXPRESS) and SQL Server Browser services were running.
CMGR_SRV -> SQL Server Network Configuration -> Protocols for SQLEXPRESS to ENABLE the Shared Memory, Named Pipes, and TCP/IP protocols and DISABLE the deprecated VIA protocol.
CMGR_SRV -> SQL Server Network Configuration -> Protocols for SQLEXPRESS -> double click TCP/IP to open the TCP/IP properties dialogue. On the Protocol tab Enabled: Yes, Keep Alive: 30000, changed Listen All to No. I've tried it both
ways, but I've got six IP addresses on my server and I wanted to configure SQLEXPRESS to listen to only the first and primary IP. On the IP Addresses tab went to IPALL and cleared the TCP Dynamic Ports field and entered 1433 in the TCP Port field.
For my first and primary IP Address I made sure that Enabled was Yes, I cleared the TCP Dynamic Ports field, and entered 1433 in the TCP Port field. For all other IP Addresses Enabled was set to No and I cleared both the TCP Dynamic Ports and TCP Port
fields.
CMGR_SRV -> SQL Server Services -> SQL Server (SQLEXPRESS) right click and Restart. This of course stopped and restarted my instance of SQLX_SRV enabling the TCP/IP configuration in the previous step to take effect.
On my server, SQLX_SRV is the only instance of SQL Server running and so it's easy to hard wire it to the default port 1433.
The instance name for both SQLX_SRV and SQLX_LOC is the default "SQLEXPRESS". My server machine name is "SERVER1" on the EnglishBrains.com domain. So the proper local name (local within the context of my remote server as connected via RDC) for
my instance of SQLX_SRV would be:
SERVER1\SQLEXPRESS
Note the use of a backslash NOT a forward slash.
Of course to connect remotely from my development machine, which is not on the same domain as my hosting server, I would need to specify the domain as well, so the SQL Server name becomes:
SERVER1.EnglishBrains.com\SQLEXPRESS
I must also use SQL Server Authentication. Before I can use such a remote connection, however, there are still several configuration steps required. So on my server (connected via RDC) I used MS_SRV to connect to SQLX_SRV using SERVER1\SQLEXPRESS
for the server name and Windows Authentication. Once connected I performed the following steps:
MS_SRV -> right click the connected parent SERVER1\SQLEXPRESS instance node at the top -> Properties -> Security -> Server authentication: select "SQL Server and Windows Authentication mode". This will enable connections using either type
of authentication.
Next, leaving the Server Properties dialogue open, Connections -> check "Allow remote connections to this server" box.
Click OK to save these changes and close the Server Properties dialogue.
MS_SRV -> Security -> right click Logins and select "New Login...", the Login - New dialogue opens.
On the General page Enter a name for your new login
Select SQL Server Authorization
Enter and confirm a password
Uncheck Enforce password expiration
Select the default Database and Language
On the ServerRoles page Public will be checked, also check SysAdmin. This is probably not a good idea and I'll uncheck this as soon as I can connect to the SQLX_SRV.
On the User Mapping page select the databases you want your new Login to access and enter the Default Schema of "dbo".
At the bottom of the User Mapping page you'll see the Database Roles table. Public will be selected by default. Also select db_Owner. Again this is probably not a good idea, and I'll refine this once I can connect.
On the Status page confirm that "Grant" is checked under "Permission to connect to database engine" and "Enable" is checked under "Login".
Click OK to save all changes and close the Login - New dialogue.
With these steps completed you should now be able to use MS_SRV to connect to SQLX_SRV using SQL Server Authentication by supplying the name and password for your new Login. I tried this and it worked fine. Next I tried to use this same login
remotely, that is I went to my local development machine and used MS_LOC to try and connect to SQLX_SRV by using
SERVER1.EnglishBrains.com\SQLEXPRESS
and opting for SQL Server Authentication and supplying the name and password of my new login.
THIS DID NOT WORK?? Instead I get the following error message:
Cannot connect to SERVER1.EnglishBrains.com\SQLEXPRESS.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider:

For help, click:

If you follow the suggested help link, you are told:
The SQL Server client cannot connect to the server. This error could be caused by one of the following reasons:
A specified SQL Server instance name is not valid.
The TCP, or named pipes protocols are not enabled.
The firewall on the server has refused the connection.
The SQL Server Browser service (sqlbrowser) is not started.
WRONG on all 4 counts! The instance name IS valid. Both TCP/IP and Named Pipes protocols are enabled. The firewall has been shut down, so it is not relevant. Finally the SQL Server Browser IS started.
The next thing I tried was to circumvent discovery by the SQL Browser service by using the following syntax to specify the IP address and port directly when specifying the SQL Server name.
tcp:68.71.134.186,1433
Using this in the Server Name field I was able to use MS_SRV to successfully connect to SQLX_SRV (using SQL Server Authentication of course) with or without the SQL Browser service running.
However when I tried to connect from MS_LOC to SQLX_SRV using this same login (WITH SQL Browser service running just for good measure) it does not work?? I get the following error message:
Cannot connect to tcp:68.71.134.186,1433.

If you follow the help link you are told:
"The SQL Server client cannot connect to the server. This error could occur because either the firewall on the server has refused the connection or the server is not configured to accept remote connections."
However, the firewall has been shut down and the server HAS been configured to accept remote connections!
I confirmed that i could indeed Ping to 68.71.134.186 and running NetStat -a |find /i "listening" on the server shows that the server is indeed listening at 68.71.134.186 Port 1433 -- which is why I was able to connect to SQLX_SRV using MS_SRV with
tcp:68.71.134.186,1433 .
IN SUMMARY: Even though I can connect to my SQLEXPRESS instance multiple ways from the server itself, I cannot connect remotely from my development machine!
If anyone can help me figure out why I would be very, very grateful!

My two cents to help you out on c# code example to configure the remote sql server express.
Hope it helps. It works, but you have to be extra carefull to read it all and setup the server configuration and netsh commands; also the port fowarding on the router.

ODBC (RDO) Connection Information : DataBase Server ID Greyed out

Post Author: Eany
CA Forum: Data Connectivity and SQL
When I select the refresh option (Crystal XI) for a report which previously worked fine, I get sent to the ODBC (RDO) connection Information screen.
The first box for Server ID is greyed out.
When I go to enter the password, I get
Login Failed
HY000 General Error : Invalid file dsn Database Vendor Error 556.
But If I then create a new report, selecting the same dsn as was used for the report above, there is no problem.

Hi Thib,
It won't work, WEB servers do not allow you to "Browse" their folder structures directly. You could how ever create a WEB Service to do this, it does the querying for you and then passes the data back. You'll have to search the WEB for more info on how to create a WEB Service and then check with your security guys if this is something you want to do.
Bottom line is ODBC or native or OLE DB is not going to work. And if you do open it up so you could it would be a major security hole for anyone to get to.
Other options are to create a VPN server so you can remotely connect to the server and get direct access to the table.
There are other options also, what you want to do is not doable.
You did not say why you want to do this? Add more info and someone may have a suggestion for you.
Major DB's like Oracle, MS SQL Server and others allow this to work through their clients so you may want to look at that option also.
Thank you
Don

What's wrong with this MySQL connection? "Could not create connection to database server"

I'm able to connect to other MySQL databases but this one particular remote MySQL connection isn't working and I cannot figure it out. It probably has something to do with the remote server, not CF, but I thought I'd post it here if anyone had an idea. The MySQL account has full priviledges.
Here is the message when I try to validate the data source:
Connection verification failed for data source: test
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
The root cause was that: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

This happened on two servers. One one, the cause was that skip-networking was turned on. In the other situation, it appears that the database name was case sensitive, so TEST was not the same as test. Even though I edited the data source in the CF administrator, it still didn't work (very misleading). When a coworker entered a new data source with the same information (uppercase database name this time from the start), it worked.
Has anyone else seen this problem with the case sensitive database names? And with the data source in CF not updating the case correctly? Seems like a bug in CF.

Can't remote connect to sql server

I have SQL Sever 2008 R2 on the cluster environment
cluster server name is A
Cluster Node 1 name is A1 (current active one)
Cluster Node2 name is A2
SQL Server name is Ab, default instance, tcp/ip port 1433
I am not able to remote connect to the server. I tried A, A1, Ab and their corresponding IP address, not of them works. Should I change to the SQL Server name to match with the cluster server name? Thanks in advance!

Dont have to change the sql server name.
In a standalone machine when you have a default instance, the sql server name is indeed the server name. But in cluster its the network name that is associated with the virtual ip for SQL.
If you try with either SQL Server Network Name or IP address it should work. If it doesnt work try forcing TCP protocol and the port number in connection and see.

MDM 71 - mdm console and clix - unable to connect to database server

Hi,
environment, MDM 7.1, AIX 6, Oracle 10.2.0.4 (installed as part of a standalone java AS)
i've an issue. I have installed MDM 71 via sapinst, before that I installed a standalone java application server. During the installation, i gave the 'oracle client', 'oracle home' and 'oracle sqlplus utility' to be those of the oracle database installed for the java AS.
After sapinst completed I tested my connection to the database via
tnsping <SID> = OK
sqlplus system/passwd@<SID> = OK
When i start up the mdm console (7.1.02.90) i can mount the MDM server, BUT when I try to configure the database settings i get
error 'unable to connect to database server'
I get the same error when i use clix dblist
Error: 0x84020004, Unable to connect with Database Server
Has anybody got any ideas.

To see why the MDM is not able to connect to database, do the following:
% cd /usr/sap/<SID>/MDSxx/log
% ls -ltr
You will find last updated log file with name like MDS_LogXXUX101224X164953.csv
% tail -100 MDS_LogXXUX101224X164953.csv
You will see the reason for not being able to connect. If the reason is:
",MDSAdminServerXGetAvailableReps,Oracle_DBConnection.cpp,205,,,,server_user,server_global,,,
2011-09-23T06:10:48.933,6       ,24,"Service 'SID', Schema 'system', ERROR CODE=12154 ||| ORA-12154: TNS:could not resolve the connect identifier specified
OCI Attach, try again ...
Then edit the /oracle/SID/112_64/network/admin/tnsnames.ora with entry like following:
SID.WORLD =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS =
        (COMMUNITY = SAP.WORLD)
        (PROTOCOL = TCP)
        (HOST = hostname)
        (PORT = PORT_NO)
    (CONNECT_DATA =
      (SID = SID)
      (GLOBAL_NAME = SID.WORLD)
then issue:
tnsping SID
If result is like
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (COMMUNITY = SAP.WORLD) (PROTOCOL = TCP) (HOST = hostname) (PORT = PORT_NO))) (CONNECT_DATA = (SID = SID) (GLOBAL_NAME = SID.WORLD)))

How to enable remote connections in SQL Server 2008

I'm trying to enable remote connections in SQL Server 2008 R2 as described in the following article. I see the error message at the top of the article.
http://blogs.msdn.com/b/walzenbach/archive/2010/04/14/how-to-enable-remote-connections-in-sql-server-2008.aspx
One step in the article describes how to enable TCP/IP in Configuration Manager.  Specifically it says that
'SQL Server NETWORK Configuration' should have TCP/IP enabled.
The issue I've encountered is that my Configuration Manager
is different than what appears in the article. My Configuration Manager shows the following:
SQL Server 2005 Services
SQL Server 2005 Network Configuration (32 bit)
      - Protocols for SQLExpress
SQL Native Client Configuration (32 bit)
       - Client protocols
       - Aliases
Note that I see 'SQL Server 2005 Network Configuration'
rather than that for 2008. When 'Protocols for SQLExpress'
is expanded, there is a TCP/IP setting, but it's disabled and I see an
Access Denied message if I try to enable this.
I also see a TCP/IP setting under Client protocols and successfully enabled this. This uses port 1433 and I configured my firewall to accomodate this port as suggested in the article.
I also followed the other steps in the article, but still don't have remote access to SQL Server 2008 R2. (I can access it from the office.) I'm wondering if this remote access issue is because SQL Server
2008 Network Configuration does not appear in Configuration Manager
and if so, I'm interested in how this might be resolved. (I'm running Windows 7 - 64 bit.)
I'd appreciate any ideas on this. Thanks.

'Unable to connect to database server' on local test server (CS4)

I am a php/MySql newb. Have designed static sites in DW since Macromedia DW 4 days.
I have set up a testing server on my Mac running OSX 10.6.7 using MAMP 1.9.5 and Dreamweaver CS4 to test my osCommerce store (I like to see what's happening visually, even if I just change a small variable in the code). Although I have imported the store database from my remote server, and the connection tests in the DW Database window to the store, mysql, and information schema databases in Dreamweaver are successful, I still get "Unable to connect to the database server!" when I try to preview a .php page with Live View or with a browser. I'm using the correct ports in my site definition (8888 and 8889). MAMP shows Apache and MySQL running, of course. Have tried logging in as root and as my ususal username witht the correct passwords. Everything seems to be right...but it's still wrong.
Do I also need to import the mysql and information schema databases from my remote server to replace the ones that came with MAMP? If so, where do I put the information schema db? Although it shows as a database in PhpMyAdmin, I don't see a folder or doc by that name anywhere in MAMP - it must be buried pretty deep! (I did find a file called information_schema_relations.lib.php in MAMP/bin/phpMyAdmin/libraries. Is that it?)
Or is it something else entirely?
Note that though I'm a fairly savvy user, I am not a developer or coder. Strictly a GUI/static design guy with a liberal arts education. Keep the answers simple and in plain English, thanks.
Have also posted this on the MAMP forum.

No Connection to database server

Hi,
I want to get access from an application server to an oracle database server via a web application (jsp file). Therefore I use Oracle 10g JDeveloper.
So I have installed Apache Tomcat (version 5.5.15) at the application server and then I built a JDeveloper demo application exactly as shown by Oracle.
Everything worked, but when I started the application I got the message "Error 400 - Unable to connect to remote host or host not responding.".
The url is "http://<ip-Address of the application server>:8988/ws_zda-proj_jsf-context-root/faces/browse.jsp", the browse.jsp file is in the directory "C:\Program files\Apache-Software-Foundation\Tomcat\webapps\ws_zda_ora10g\proj_jsf\public_html".
By using th url "http://localhost:8080/ws_zda_ora10g/proj_jsf/public_html/browse.jsp" I get the Tomcat message "HTTP Status 404 - The requested resource is not available.".
Do I use a wrong port 8988 or is there an error in "ws_zda-proj_jsf-context-root" or what do I have to change?
I think there must be something wrong at the configuration.
I don't have any problems with watching the database in JDeveloper. So the JDBC configuration seems to be correct.
Regards
Toni

Apache Tomcat default port is 8080.Using 8080 doesn't make a difference.
HTTP Status 404 - The requested resource is not available indicates web server is not started.Tomcat service is running. Is there anything else that must be started?

How to connect several database server

I want to build a web site using jsp servlet for my university course purpose. In the background i will have three servers one is database server like server A another is certificate authority server like server B and the other one is Bank server like server C. Next, user will input through login page(say for example user name & password for database server A, certificate credentials for server B) then the login page will check user credentials kept in server A and at the same time with server B(CA server). If the user credentials kept in both of these servers(A &B) are matched then the page will inform that this is the valid user and connect to the bank server for money transaction. I hope now the my problem is clear to you. please answer me how can i prepare for that.

Can't remotely connect to my server if I automatically set date and time

Hello.
I have configured my OS X 10.6.2 server and am able to remotely manage it.
The only ports I have opened on my router is for Mail and VPN services.
Things work perfectly because I can connect using VPN to iChat, iCal, Address Book, Server Admin, Workgroup Manager, AFP, FTP and such.
The problem is that on my laptop from home, or wherever, if its time is set to update automatically from an NTP server (I have tried with Apple's as well as my server for the NTP Servers) then I cannot connect to my server at all...
The moment I turn off the auto date and time and reconnect to the office's VPN, I am able to use Server Admin, AFP, FTP, Workgroup Manager, Screen Sharing, etc, etc, etc.
It's utterly frustrating because I have to open system preferences, disable the automatic date and time update, connect to the VPN and do stuff on the server. Then I have to disconnect from VPN and re enable the auto date and time.
Could someone explain why this is happening and any possible solutions I might be able to try?
Thanks in advance,
Felipe.

OK, after some testing things seem to be working now.
I opened the NTP port for my server (So I don't have to be on VPN to update the time)....But regardless of that, Server admin and my corporate site work fine.
Here is my problem, I don't understand why it's working now when 30 minutes ago I was having trouble connecting to my server regardless of what NTP Server I used.
The only service I can't access is Workgroup Manager, but I don't know if that is supposed to be accessible only locally (though it doesn't matter since I can screen share but I would still like to know).
Thanks in advance,
Felipe.

Unable to connect with Database server in MDM

Hi Experts,
I have installed the MDM server 7.1 on windows 64 bit box, but installed MDM console (32 bit).
Getting the issue like below
Can anybody please help me out to fix the issue.
Thanks in advance,
Bhaskar N

dear
Did you install Oracle client on MDM server. If not please install it and revert with the result..
Please check SAP Note 1350635 - "Problem connecting to database from MDM console" & Note 1363797 -" Oracle connection problem".. Kindly also check the log in MDM console and revert with the result.
Also, Please check Configurations Settings as mention in [MDM installation Document|https://websmp209.sap-ag.de/~sapidb/011000358700001668492008E] from Page no 42 to 45.
do the following
You need to create tnsnames.ora file even on the host where MDM is installed and define Oracle database host and instance there. Then, MDM user needs to have access to oracle client libraries and needs to have access to this tnsnames.ora file as well. Once you set this up, it will work fine.
