Veeam Off-Host Proxy creating redundant iSCSI connections

Not sure this is a Veeam issue, just that it's occurring with Veeam backup process.
We have a server configured as an Off-Host Proxy with Veeam; it connects to the SAN storage via iSCSI same as the other hosts but accesses the storage as read only.
Randomly we will get alerts from the SAN as below:
iSCSI login to target '172.16.0.50:3260, iqn.2001-05.com.equallogic:8-661fc6-e612eedc6-32600005c9254a75-arcvmstore1-2015-01-03-14:13:37.2774.1' from initiator '172.16.0.44:64108, iqn.1991-05.com.microsoft:arcbackproxy.domain.local' failed for the following reason:
Requested target not found.
On inspection of the Off-Host Proxy's iSCSI configuration additional iSCSI connections are present as inactive, with an existing connections name amended with the date at the end. For instance (and in the example error above) there will be:
iqn.2001-05.com.equallogic:8-661fc6-e612eedc6-32600005c9254a75-arcvmstore1
and
iqn.2001-05.com.equallogic:8-661fc6-e612eedc6-32600005c9254a75-arcvmstore1-2015-01-03-14:13:37.2774.1
Not really causing an issue, the backups are running OK, or any issues we have aren't related. But getting annoying getting the alerts from the SAN of the Off-Host Proxy trying to connect to an incorrect iSCSI target.
Any ideas why this is occurring?
Obvious is we delete the extra connection, which stops the alert, but the issue will reoccur within a day or two usually.

Hi,
Is there any error message in the Event Log? Please try to use the Windows Server Backup to check if you can run a backup.

Off-host backups

Hi,I am investigating using DPM2012 as a backup solution for our Hyper-v Cluster with HP P4000 SAN . We currently use HP Data Protector which has the facility to carry out Off-host backups and disk to disk backup. These options are license products
which costs a lot of money, where as DPM is included with System Centre. DPM includes Disk to disk backups(guest and host) but is it possible to carry out a Off-host backup (Transportable). I have tested a hardware VSS backup but the data goes
over the management network where I would like to keep the data over the ISCSI network. Thanks in advance.
Cheers
Adrian

Adrian,
I have DPM 2012 R2 backing up a HV 2012 R2 cluster. One of the SANs we have is a HP P4000. VSS hardware writers work..........but as you discovered...........the backups go over regular TCP/IP network...........not over iSCSI. Same thing happens
for our other FC connected SAN, a 3PAR 7400.
What I want is a Transportable backup, sometimes it needs an off-host proxy, like Veeam does.
HP says transportable backups can work on HP Dataprotector, NetBackup and Backup Exec. We gave up on Data Protector because of its huge cost. Commvault also does it but again, very expensive. Veeam does it, but in their own way...and of course it is
pricey,,,,maybe not that much.
I am also looking for an answer....so far I see that DPM does not have this feature.

ISCSI connections for guests: how to set up?

A couple of questions:
1. If we wanted to set up iSCSI connections for guests such as SQL servers, what is the best way to handle this? For example, if we had four 10-Gb NICs and wanted to use as few of them as possible, is it common to turn two of the NICs into Virtual Switches
accessible by the OS, then use these to connect both the host and the SQL guests? Or would the best option be to use two 10-Gb NICs for the Hyper-V Host's iSCSI connections only, and use the other two 10-Gb NICs as virtual switches which are dedicated
to the SQL server iSCSI connections?
2. I know MPIO should be used for storage connections instead of teaming; if two NICs are teamed as a virtual switch, however, does this change anything? For example, if a virtual switch is created from a NIC team of two 10-Gb NICs, is it acceptable to create
an iSCSI connection on a network adapter created on that virtual switch?

" If we wanted to set up iSCSI connections for guests such as SQL servers, what is the best way to handle this?"
Don't. Use VHDX files instead. A common reason for using iSCSI for SQL was to allow for shared storage in a SQL cluster. 2012 R2 introduces the capability to use shared vhdx files. It is much easier to set up and will likely
give you as good, or better performance, that iSCSI.
But, if you insist on setting it up, set it up the same as you would on the host. Two NICs on different subnets configured with MPIO. (Unless using Dell's software which forces a non-standard configuration of both NICs on the same subnet). Teamed
NICs are not supported. For a purely best practice configuration, yes, it makes sense to have separate NICs for host and guest, but it is not an absolute requirement.

What do you mean by "off host"? Do you want to have backup software running directly on top of EQL firmware? Or do you want to avoid proxy servers and have steady stream from EQL to backup storage?

How to create a new connection from SAPGUI to Test drive?

Hi,
I have installed Sap Netweaver Test drive on a linux virtual machine (windows host). The installation was successful and I was able to start the instance (application server and the database), yet I don't know how to create a new connection from my SAPGUI client (7.20) to this server. The static IP address of the server is 192.168.1.160.
I entered the following values for my new connection entry
Description: SAP Netweaver
Application server: 192.168.1.160
Instance number: 01
System ID: DB2
SAProuter: /H/192.168.1.160/S/3201/H/
But it does not work. Any idea about the values needed for creating a new entry?
Thanks in advance,

Hi Mohit,
Thanks for ur response and it helps me to explore more. But, still after adding the oracle jar file in E:\Hyperion\deployments\Tomcat5\WebAnalysis\webapps\WebAnalysis\WEB-INF\lib(this path does reside on my remote), it giving the same error.
I think following details will help u to judge the exact scenario :
DataBase connection string is correct :- jdbc:oracle:thin:@ugdwpi1.cos.abc.com:1521:GDWDB
where Port no.- *1521* , Server Name - ugdwpi1.cos.abc.com

CLASSPATH is - E:\oracle\product\10.2.0\client_1\jdbc\lib\ojdbc14.jar
JDBC Driver is : oracle.jdbc.driver.OracleDriver
TNS enrty is :
GDWDEV =

(ADDRESS = (PROTOCOL = TCP)(HOST = ugdwpi1.cos.abc.com)(PORT = 1521))
(CONNECT_DATA =

Getting Error while creating Integration server Connection ...PLS help me

Hi everybody,
While creating the Integration server connection I am getting the below error.
Please help me to solve it.
I am using 10.1.3.1 .
Application Server: OK
BPEL Process Manager Server: FAILED
ESB Server: FAILED
Thanks in advance.
Ramana

Now i can able to login to my weblogic admin console and find that listen address is blank i have given the listen address as localhost now i can able to create the application server connection successfully ...Listen address blank means your server will accept connections on all network addresses i.e. on localhost, on 127.0.0.1 and on IP/Host name of machine
If you want to access this server from a remote machine as well, then better keep the listen address field as blank OR assign the value of hostname/IP of machine as listen address. In case you set listen address as hostname/IP of machine, server will not listen anymore to localhost or 127.0.0.1
1)Now iam working in local machine so that i am giving localhost .... In case i doing some bpel work in my local machine and after completing the work if want to move to my server ...do i want to change the connectionand give my server hostname ha?If your BPEL server is a remote server then better create a new connection for that (using listen address and port of that server)
How to see errors in Admin server log C:\Oracle\Middleware\user_projects\domains\Soa_base_domain\servers\AdminServer\logs ...is it i want to check it here?Yes, you need to check the logs in this directory in file AdminServer.log
How to check this?Under $Domain_Home/bin (C:\Oracle\Middleware\user_projects\domains\Soa_base_domain\bin), there will be a file setSOADomainEnv.cmd. If you open this file using notepad, you would see a setting like below -

BEST PRACTICES FOR CREATING DISCOVERER DATABASE CONNECTION -PUBLIC VS. PRIV

I have enabled SSO for Discoverer. So when you browse to http://host:port/discoverer/viewer you get prompted for your SSO
username/password. I have enabled users to create their own private
connections. I log in as portal and created a private connection. I then from
Oracle Portal create a portlet and add a discoverer worksheet using the private
connection that I created as the portal user. This works fine...users access
the portal they can see the worksheet. When they click the analyze link, the
users are prompted to enter a password for the private connection. The
following message is displayed:
The item you are requesting requires you to enter a password. This could occur because this is a private connection or
because the public connection password was invalid. Please enter the correct
password now to continue.
I originally created a public connection...and then follow the same steps from Oracle portal to create the portlet and display the
worksheet. Worksheet is displayed properly from Portal, when users click the
analyze link they are taken to Discoverer Viewer without having to enter a
password. The problem with this is that when a user browses to
http://host:port/discoverer/viewer they enter their SSO information and then
any user with an SSO account can see the public connection...very insecure!
When private connections are used, no connection information is displayed to
SSO users when logging into Discoverer Viewer.
For the very first step, when editing the Worksheet portlet from Portal, I enter the following for Database
Connections:
Publisher: I choose either the private or public connection that I created
Users Logged In: Display same data to all users using connection (Publisher's Connection)
Users Not Logged In: Do no display data
My question is what are the best practices for creating Discoverer Database
Connections.
Is there a way to create a public connection, but not display it in at http://host:port/discoverer/viewer?
Can I restrict access to http://host:port/discoverer/viewer to specific SSO users?
So overall, I want roughly 40 users to have access to my Portal Page Group. I then want to
display portlets with Discoverer worksheets. Certain worksheets I want to have
the ability to display the analyze link. When the SSO user clicks on this they
will be taken to Discoverer Viewer and prompted for no logon information. All
SSO users will see the same data...there is no need to restrict access based on
SSO username...1 database user will be set up in either the public or private
connection.

You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
So that it won't ask for password.
Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information

Can't Create the ODBC connection for Oracle 10g

Hi,
I am working with Oracle 10g Database Release 2 in windows XP professional. I am trying to create an ODBC connection for oracle but become failure because its generating the following errors:
system error code 998
could not locate the setup or translator library
Please help me how can I solve this problem and create the ODBC connection for oracle 10g database.

The odbc driver config routine will search directories listed in PATH variable for necessary libraries (Client dll's). If some library fails to load (from e.g. oraoci*.dll or oraclient10.dll) it will probably error out, as in your case.
Are you creating the odbc dsn on the databse server host or on some other machine? I.e. are you using the db host as a client or not?

Cannot create a new connection

I have created connections in the past with no problems. Today I upgraded to V2 and had exported my connections and so imported them to the new version. Since then I cannot create a new connection.
Right clicking and selecting New Connection does nothing, whereas clicking new and selecting Database Connection results in a java.lang.NullPointerException error.
I have done a full re-install of Raptor from the original files and switched off my PC, but no luck.

Gareth, try the existing thread, and see if that helps:

Create RAC Database Connection in Sql Developer

Hi All,
Can you please let me know how to create a new connection for a RAC Database. When we use the scan IP and service name, it always displays the network adapter could not establish the connection, even though the listener and database are up and running. After repeatedly, trying atlease 20 times, then it will connect to the database. There are no issue while connecting to a single instance database.
Thanks & Regards,
Krishna

Hi Krishna,
You don't give any details about version numbers but, in general, the Basic connection type should work -- there is no need to use TNSNames. If you can connect to the RAC system via SQL*Plus with an EZConnect string, one would hope the same host/port/service works in SQL Developer for a Basic connection type. But that may be just a hope, I suppose, depending on your overall configuration for SCAN. Or perhaps you pass the full TNS descriptor to connect to SQL*Plus?
In case of long thin RAC JDBC URL, presumably you mean including the full TNS descriptor in the url. I really did not find very much on the forums regarding SCAN, but searching more widely on the internet I note someone resolving a JDBC-specific issue (where SQL*Plus connects just fine) with comments like this: +"The host name in the connectiong string be the same as the init.ora parameter remote_listener and it should also match to the SCAN name. We should not include any domain names with SCAN name , remote_listername and with HOST setting in connecting string"+. So apparently you have to be very careful with the url specification.
Hope this helps,
Gary

Proxy Authorization with COS connection limits Issue

Any one having issues with connection limits (nsSizeLimit, nsTimeLimit, etc) be applied on connections that come from the proxy server with the proxy authorization control?
Example:
nsSizeLimit is set on user A to 2000, via a COS Pointer definition. If user A connects directly to the directory the nsSizeLimit of 2000 is used. If user A connects through the proxy, and the proxy connection to the directory is through a proxy authorization connection via ID admin1, the limit is not applied and the system default limit 1000 is applied.
If I over-ride the COS value for nsSizeLimit and say its 3000. If I use the proxy connection in this case the limit of 3000 is used. So it only fails for COS settings.
All the ACI's are being correctly applied via the proxy connection just not the connection limits. So basically I can't get the limits to work when I have a COS value being used via the proxy authorization user.
Any ideas on how I can get around this. I want to avoid having to enter in the different limits into entries. Also using the limits in the proxy would create to many connection handlers.
Thanks for any help you can give.
Cory

Hi,
I don't think that connection limits (Time, Size and Throughput) for User A can apply to operations that are using the Proxy Authorization for that user. Proxy Authz is a delegation of Authorization for the ACI, and does not apply to Connection specific limits.

Ludovic.
