Differance in Active Passive Twinax Cable

I have 2 Nexus 7000 and 2 Nexus 5000 which connect to FI and the UCS. What I am doing is we purchased the APC racks that allow for able management for the Nexus 7000. I am making the move in a couple step process in order for the least amount of downtime. The distance from the Nexus equipment will be about 10m away at longest. I see that my Nexus 7000 are connected using the SFP-H10GB-ACU7M and can purchase the SFP-H10GB-ACU10M. This is an Active cable. But the Nexus 7000 are connected to the Nexus 5000 using the SFP-H10GB-CU5M which is a passive cable. I have been trying to find a CU10M but the longest is 7M. From what I have found on the cisco site at the bottom link. I do not know what the difference is of the Active and Passive cable and having problems googleing what the difference is. Could I get some clarity?

SFP-H10GB-ACU10M=
10-m 10G SFP+ Twinax cable assembly, active
SFP-H10GB-CU5M=
5-m 10G SFP+ Twinax cable assembly, passive

passive twinax max distance is 5m, if you need more, e.g. 7 and 10m, you need active twinax.
Active copper cables contain electrical components in the connectors that boost signal levels. This makes active copper cables slightly more expensive than passive copper cables; however, they can connect the Converged Network Adapter (CNA) to a top-of-the-rack switch over longer distances than passive copper cables.

SFP+ Twinax cable compatibility

Hi Guys,
Does anybody know if the 'SFP+ Twinax' active or passive cables are compatable with the HP ethernet 10gb 2-port 530sfp+ adapters? I'm struggling to find/confirm if they are compatible or not.
Cheers

I've purchased a SFP-H10GB-CU3M (non-branded) TwinAx cable and have successfully connected from a HP NC552SFP 10Gb 2-port adapter (HP DL360p Gen8) into a 3750X (WS-C3750X-24T-S) 10GB (C3KX-NM-10G) module.
Once I receive my 4500X-16SFP switch, I hope to connect this into 3 dual port 10Gb vSphere hosts as well as my VNX SAN (10Gb SFP).
Finding anyone from EMC or Cisco that will confirm this solution is possible was impossible...so I hope mine will work!

Cisco Twinax Cables Compatibiltiy with EMC VNX/VNXe

Hi,
I would like to know about Cisco Twinax Cables Compatibiltiy with EMC VNX/VNXe series storage - for connectivity between UCS Fabric Interconnect and EMC VNX/VNXe.
Are the following Cisco Twinax Cables compatible with EMC's VNX and VNXe serie platforms:
SFP-H10GB-CU1M= 1-m 10G SFP+ Twinax cable assembly, passive
SFP-H10GB-CU3M= 3-m 10G SFP+ Twinax cable assembly, passive
SFP-H10GB-CU5M= 5-m 10G SFP+ Twinax cable assembly, passive
SFP-H10GB-ACU7M= 7-m 10G SFP+ Twinax cable assembly, active
SFP-H10GB-ACU10M= 10-m 10G SFP+ Twinax cable assembly, active
Kindly advice. Thanks.

Hi,
I'd like to confirm you, that passive assembly is supported. Haven't tried the actives one yet.
I'm using UCS-B200 M3, and EMC VNX 5300.
the EMC VNX5300 (Block Level) connected using 2 type of media. Copper (SFP-H10GB-CU5M= 5-m 10G SFP+ Twinax cable assembly, passive) and Fiber Channel 8 GB directly info Fabric Interconnect 6248 ports.
For old server the connection is via iSCSI 10GB Copper. and for UCS-B200 M3 is via FC 8GB.
All my configuration is running well.
Hope thats helped.
Thanks,
Pieter

Non-domain user authentication against SSAS on Active/Passive Cluster

Hello,
We have an Active/Passive SQL Server setup (DB1 & DB2 Servers) connected to a cluster for SQL & SSAS. I have a web server not on the same domain that I am trying to authenticate with SSAS. This works OK if I set the website to impersonate
myUser and I add local account myUser as an Admin on SSAS for the active server (DB1). But when this fails over to DB2 then it fails to authenticate. SSAS won't allow us to add myUser as an admin for local accounts on both DB1 & DB2 as it errors
adding the second one. Could anyone advise how such a scenario should be approached?
We have tried creating a domain user too which DB1 & DB2 can of course both share but I don't think the web server can impersonate this with being not part of the domain.
Thanks.

Hi Jcorker,
According to your description, you need to access the SQL Serve Analysis Services database which is configured as cluster for SQL & SSAS from another domain, right?
In SSAS we can use the solution below achieve the requirement.
1.Create new domain account and impersonate the web site with that.
2.Create local user account on the analysis service with same exact username/password as like domain account created in the previous step.
However, you cannot create a local account with the same name on both servers. I have tested it on my local environemnt, we can create the same local account with the same name on both servers. In your scenario, if DB1 and DB2 on different server, you can
create a local account with the same name on both servers. Please post the detail errors, so that we can make further analysis.
Besides, SSAS only allows users of the same domain or trusted domains and it does not allow users from any domain except from these two. You can configure the trust relationship between the domains.

How to : Active/Passive and Active/Active Enterprise manager R3 (10.2.0.3)

Soon I will implement the above named version of EMR3 on a AIX 5.3.3 platform. I have a couple of questions about active/passive and active/active implementations. These are the questions I have:
Basic install:
Implementing 10.2.0.2 and upgrading to 10.2.0.3 works fine on host 1234 (already done that).
Does anyone have experience with an implementation on host 1234', in other words, a virtual host (different IP-numbers on the same ethernet adapter)?
Active/passive
Lets assume that the implementation on server 1234' works fine, how can I realise a cold failover situation? On AIX you can move/transport the volume group to the failover server, activate the volume group, mount your filesystems and the application is running again. This is the theory but ....
Active/Active
If this 'basic' install is done, can someone briefly tell me how to migrate the OMS repository to a RAC implementation? Is this possible or do I need to setup the repository for the OMS at the start of the implementation. Has anyone experience with using virtual hostnames, RAC and EMR3.
Can anyone tell me where I can find some good documentation instead of reading all these thousands of pages of Oracle's guides.
Help would be appreciated.

Load balancing in Active-Passive architecture

1) Is it possible to have load balancing in Active-Passive architecture?
2) Pros & cons of RAC and Vertias cluster
Cheers,
Ashok Kumar C.

Note:183408.1
Note:259301.1
Please see the above notes for anwers. Hope it helps.
Though Oracle says that it does not need third party cluster software for RAC installation (Note:259301.1)
, my experience on AIX was different, without HACMP in place we could not install Oracle CRS.
On windows and Linux you do not need third party cluster software (Note:183408.1) ) and I did not need to use any third party cluster software on Linux platform.

DATA GUARD IN ACTIVE PASSIVE OS CLUSTER WINDOWS

Hello Gurus
I am setting up data guard in sap on windows with active passive OS clustering.
Please clear below 3 confusions.
1)I have same database name and sid of standby database as primary.Now to have different service i am just using it in setting parameters and tns_alias like
Listener file for primary and standby same as sid same
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=PROD)
(ORACLE_HOME=/oracle/product/11.2.0)
(SID_NAME=PROD)
tNSNAMES adding entry on primary as
PROD2
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=dev-db2)
(port=1521)
(connect_data=
(service_name=prod2
server=dedicated)))
tnsnames added entry on standby of primary
PROD
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=dev-db2)
(port=1521)
(connect_data=
(service_name=prod
server=dedicated)))
---->in parameter i am using service for standby as
alter system set log_archive_dest_2='service=PROD2 async valid_for=(online_logfile,primary_role) db_unique_name=prod2;
**But i have am not creating any service as such.Will THIS WORK and alright.
as i am having confusion that my SID is same so how service be differentiated.am i doing right way.
2)as my primary database having 2 node in OS cluster so like node1 having ip 192.68.2.22 node 2 ip 192.68.2.23..They are in active passive clusten.the datafiles and other oracle files can be shifted to any node as per requirement.So they are using a virtual ip 192.68.2.20.. Now i need to create standby for this primary....standby ip is 192.68.2.40
So in tnsnames i am giving all ips the virtual ip 192.68.2.20 and host ips of both nodes on standby tnsnames and on primary adding entry of standby ip 192.68.2.40.Means i am doing entries of virtual ip and host of node1 and node2.
So i am able to ping the virtual ip from standby but not able to ping 192.68.2.22 and 192.68.2.23.
So is it fine .Would i be able to create standby database as only virtual will be needed or i am going on wrong path.
3)Can i just create the standby database by using duplicate command without taking backup in 11g.(means without physical copy of data files etc from primary to standby)
likewise
On the primary server, connect to Primary database(ORCL) as target and standby database(ORCL_DTGD) as auxiliary.
$ rman target sys/sys@ORCL auxiliary sys/sys@ORCL_DTGD
RMAN>DUPLICATE TARGET DATABASE FOR STANDBY FROM ACTIVE DATABASE DORECOVER
SPFILE SET DB_UNIQUE_NAME='ORCL_DTGD' SET LOG_ARCHIVE_DEST_2='service=ORCL LGWR SYNC REGISTER VALID_FOR=(online_logfile,primary_role)' Set STANDBY_FILE_MANAGEMENT='AUTO' SET FAL_SERVER='ORCL' SET FAL_CLIENT='ORCL_DTGD' SET CONTROL_FILES='/data/oracle/app/oracle/oradata/ORCL/control01.ctl’,'/data/oracle/app/oracle/fast_recovery_area/ORCL/control02.ctl’ NOFILENAMECHECK;
after configuring tns,listener etc
Regards
thanks for ur time..please reply as i am really looking for ur great ideas and need them.

For Question 1:
The SERVICE attribute, which is a mandatory attribute for a redo transport
destination, must be the first attribute specified in the attribute list. The SERVICE
attribute is used to specify the Oracle Net service name used to connect to the redo
transport destination. The service name must be resolvable through an Oracle Net
naming method to an Oracle Net connect descriptor that matches the Oracle Net
listener(s) at the redo transport destination.
Source - 6.2.2 Configuring an Oracle Database to Send Redo Data
Concepts and Administration 11g Release 2 (11.2) E10700-02
For Question 2:
I would DNS if possible. If you cannot see IP's you can add them the the HOSTs file on most OS's as a work around.
Not sure what you are trying to do exactly.
For Question 3:
Yes.
Duplicate for Standby using active duplicate.

MSSQL2012 active/passive cluster convert to active/active cluster

Good day.
We have 2-node active/passive MSSQL2012 cluster (on Win 2008 R2). One "default" instance.
We want convert to active-active, (multi-instance).
As I understand, one SQL instance (existing) will run on 1 cluster node and the second (new) instance on the 2 cluster node.
I have some questions:
- we have cluster virtual name and ip address for existing MSSQL instance, for the second MSSQL instance we need to create another name and ip ?
- for second MSSQL instance we can create 2 separate cluster disks (for DB and LOGS) ?
- for second MSSQL instance we can create another DTC instance and bind it to the second MSSQL instance ?
- we can use existing physical LAN connectors on our servers (data and heartbeat) or we need to add new LAN adaptors ?
- quorum disk is the same for all instances ?
Sorry for my bad English.

I have some questions:
- we have cluster virtual name and ip address for existing MSSQL instance, for the second MSSQL instance we need to create another name and ip ?
Yes that would be required.
- for second MSSQL instance we can create 2 separate cluster disks (for DB and LOGS) ?
Yes it will be in different resource group and you can have different disk for them.
- for second MSSQL instance we can create another DTC instance and bind it to the second MSSQL instance ?
Same MSDTC can be used for multiple instance.

- we can use existing physical LAN connectors on our servers (data and heartbeat) or we need to add new LAN adaptors ?
Best to ask network team
- quorum disk is the same for all instances ?
Quorum is for windows cluster not for SQL server so Yes its same for all instances
Sorry for my bad English.

Active Passive Vs Active Active

Hi All,
How much more effort it requires to failover or get up and ready with passive node, if Active Passive strategy is followed rather than Active Active just for saving on licenses.
Note : High availability is not a concern.
thanks,

Be clear what the policy means. RAC is normally considered an ACTIVE/ACTIVE solution since all nodes in RAC are actively processing. In an ACTIVE/PASSIVE setup by contrast one or more nodes are actively processing whilst others are standing by ready to take over the workload in the event of failure of the primary. Physical Standby, Failsafe and non-oracle clusters are often Active/Passive. You may also check if the policy comes from a sqlserver centric view of the world where you split the sqlserver databases between different nodes, so that although for any given sql database the solution is active passive, you don't 'waste' the resources of some nodes just waiting to take over, but rather run other databases on them.
Your description of ACTIVE/ACTIVE seems to rather correspond to a Stretch Cluster http://www.oracle.com/technology/deploy/availability/pdf/1126_Ray_WP.pdf has a good overview of what this means. I'd be surprised if the policy was really to put all databases on just about the most expensive hardware and software solution available, but I'm used to surprises in the world of corporate policies.

(As apposed to a couple mutinode RAC setups with a primary\standby database)
Any white papers or best practice document references would be great. I'd hate to do this just case of some policy.

New 10 Meter twinax cable

According to the updated compatibility matrix, the new 10 Meter twinax SFP-H10GB-ACU10M cable does not show interoperability with the Catalyst 6500 67xx 10 Gig linecards (With CVR-X2-SFP10G converter for X2 ports). The shorter 1-5 meter twinax cables show that they are interoperable.
http://www.cisco.com/en/US/partner/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6974.html
Does anyone know if this is incorrect and just not yet updated.
Thanks.

I suspect it might have something to do with the CVR-X2-SFP10G, seeing that the converter module data sheet also does not list any length of the Active Twinax cables being compatible.
I am trying to reach out to someone within the Product Mgmt org to see if they can provide an answer... but my contacts are old....

Install of Data Services as active/passive behind F5 load balancers

I currently have two RedHat 5.5 x86_64 hosts, SAP_DS1 and SAP_DS2, and 1 database, Oracle RAC 11g and 1 F5 LTM load balancer sitting in front of the two hosts. The F5 load balancer VIP is set up as active/passive (fail-over) for the two hosts.
Will I need 2 local databases 1 central database or can I accomplish this with one local database?
Please advise on the recommended method for installing BOBJ DATA SERVICES XI 3.2 on two Linux hosts in an active/passive design.
Thanks

You might have better luck asking this question in the (somewhat misnamed) [Data Integration and Data Quality Management|Data Services and Data Quality; forum:

Can you Setup a Active Passive DFS namespace in the same site

Hi,
I would like to use DFS for profile replication. I know MS doesn't recommend it, but was wondering if you could setup DFS namespace in an Active/ passive contests in the same AD site. I think or what I can understand of DFS is that if the Fileserver is in
the same site it would select it randomly and you cant specify which server is the primary.
Basically what I want is to have users only access File server 1, but if this file server 1 goes down to be redirected to file server 2.
Thanks,
Shaun

You could have a read-only Replica but that really doesn't help you in terms of the automatic redirection thing. You could also set up a 2-node replication group and disable the referral for the folder(s) on one node like below:
However the "failover" would be manually Enabling, which I doubt fits the bill.
Otherwise, I'm not aware of any configuration of DFSR that allows you to do what you're talking about (maybe someone else will correct me.) HOWEVER, I suspect a design that fits your use case may be to create a DFS namespace that runs
on a file server cluster. That way if Node1 goes down, the cluster fails over, and the data continues to be available on Node2 when accessed via DFS.
If interested, there are a couple ways to approach DFS in combination with a cluster.
Configuration1: The cluster is configured to host the namespace as well as the folder targets (where the actual data is). CAVEAT - The cluster can only be configured as a standalone cluster.
Configuration2: Create a domain DFS namespace that resides on other servers.
\\domain\DFSRoot for example. Then point each of the leaves/folder targets to clustered shares. So you'd create a subfolder called "Profiles" that points to the clustered share that houses the profiles.
Just an idea. Hope this helps.

Error with concurrent users- Activation Passivation Bind variable ?

I have a programmatic view object based on procedure call that returns a ref cursor.
Application Module has a function that exposes get Method for this View object using client interface.
Everything works good until many users call the same Method ,for many concurrent users i got the below error intermittently :
JBO-27122: SQL error during statement preparation.
Attempt to set a parameter name that does not occur in the SQL: bussId
For 1 or 2 users this works perfectly fine.
bussId is a bind variable defined at View object of type Array.
I understand this should be because of activation/passivation as many users calling same function comes to picture.
To solve this I overloaded activateState/passivateState in View implementation for the bind var.
But i don't see those methods getting invoked ever.
I also enabled connection pool/AM pool and kept the default pool values high enough for concurrent users.
Nothing works .
Appreciate any help in this regard.
