How many SCAN listners for 2 node rac ?

Hi,
Oracle recommends min 3 SCAN listeners , but what if I've got 2 node RAC ? :)
Regards
GregG

Hi Friend
About SCAN :
1. The single client access name (SCAN) is the address used by all clients connecting to the cluster.
2. The SCAN name is a domain name registered to three IP addresses, either in the domain name service (DNS) or the Grid Naming Service (GNS).
3. The SCAN name eliminates the need to change clients when nodes are added to or removed from the cluster.
4. Clients using SCAN names can also access the cluster using EZCONNECT.
5. The Single Client Access Name (SCAN) is a domain name that resolves to all the addresses allocated for the SCAN name.
6. Three IP addresses should be provided (in DNS) to use for SCAN name mapping as this ensures high availability.
7. During Oracle Grid Infrastructure installation, listeners are created for each of the SCAN addresses, and Oracle Grid Infrastructure controls which server responds to a
SCAN address request.
8. The SCAN addresses need to be on the same subnet as the VIP addresses for nodes in the cluster.
Note 1 : SCAN IPs must NOT be in the /etc/hosts file, the SCAN name must be resolved by DNS.
Note 2 : When you are installing Grid Infrastructure it will ask for the following things :
*1. Cluster Name :*
*2. Scan Name :*
*3. Scan Port :*

How many Scan Listeners, we have to configure for 5 Node RAC?

Dear Professionals,
How many scan Listeners we need to configure for 5 Node RAC? Oracle will not allow us to create More than 3 scan's? What If i have one scan Listener per each for 1st 3 node's? what about remaining two Node's? How application user will connect to 4 or 5 Node? Can you please explain..? Forgive me, If am totally wrong?
Thanks
Sagar

Each of the 5 instances will register itself with the scan listener (using the instance parameter remote_listener). Thus, the scan listener is "aware" of the database instances on the other two nodes where it is not running. It can still redirect incoming connections to the local listeners on these nodes (registered as local_listener).

How many scan ?

Hi,
I have 2 node rac with configured scan listener, how many scan's am i suppose to have by default?
[grid@node1 ~]$ crs_stat | grep SCAN
NAME=ora.LISTENER_SCAN1.lsnr
I seem to have one resources and one scan1 which can run against any node ... am I missing LISTENER_SCAN2?

Take a look to this Oracle white paper at: http://www.oracle.com/technology/products/database/clustering/pdf/scan.pdf
SCAN CONFIGURATION IN THE CLUSTER
"During cluster configuration, several resources are created in the cluster for SCAN. For each of the 3 IP addresses
that the SCAN resolves to, a SCAN VIP resource is created and a SCAN Listener is created. The SCAN Listener is
dependent on the SCAN VIP and the 3 SCAN VIPs (along with their associated listeners) will be dispersed across the
cluster. This means we will try to run each pair of resources on a different node in the cluster. If the node where a
SCAN VIP is running fails, the SCAN VIP and its associated listener will failover to another node in the cluster."

For 4 node RAC database on Exadata x3-2, how many scan IP I should assign?

We want to build a 4 node RAC 11gr23 on exadata x3-2. Oracle only recommend 3 ip for scan listener. by previous observation of non-exadata RAC, seems each node will spread randomly one Scan Ip address. So if we assign 3 ip to one scan listener, how that will work on a 4-node RAC?
Thanks

You're welcome
by Load balancing
Oracle RAC databases increase load balancing by using the single client access name (SCAN) for the cluster to balance connections among all instances in a cluster database. SCAN also adds location independence for the databases, so that client configuration does not have to depend on which nodes are running a particular database or database instance.
http://docs.oracle.com/cd/E11882_01/install.112/e48195/undrstnd.htm#RIWIN607
Based on the environment, the following actions occur when you use SCAN to connect to an Oracle RAC database using a service name. The numbered actions correspond to the arrows shown in Figure 7-1.

How many egift cards for one order?

I had emailed customer service asking how many egift cards could be used for one online order, and I was told you could use 5 per online order, and 10 in store. But then I saw this link in the customer service catagory, and it says you can use 10 gift cards per online order.
http://www.bestbuy.com/site/help-topics/gift-cards/pcmcat203400050004.c?id=pcmcat203400050004
Can I use 5 or 10 gift cards for a online order? I have 7 $100 gift cards I want to use to make a online purchase. Thank you.

Hello stephanielynett,
Thank you for posting your concern on Best Buy Unboxed forum. Ready to use the e-gift cards that you have been saving from Birthdays and special occasions, and not sure on how many can be used in an order, can have an impact on how you place your order.
To the best of my knowledge, the most updated information is found on the link that you shared on this forum. You should be able to use to 10 e-gift cards per order.
Have a great day,

Minimum How many dimension required for FDM integration Script

Hi Gurus
I have only 2 dimensions in my SQL Table name dbo.ABC (Example: 1.Entity 2.Account and amount(data value)
Example:
USA, SALES, 50000
(Including value its total 3 dimensions)
How to export this data to Target HFM Application.
Integration Script got success when i click on validation it is shows only 2 dimension 1.Account 2.Entity. i have mapped correctly. but validation screen not showing anything. i got gold fish for validation button and Export is also showing success and got goldfish. but no data is exported to HFM application.
in FDM outbox its created a file which is containing only *!data* text. There is no record in this file.
I want to load the data with rest of the dimensions with [None] member combination as i don't have the additional dimensions in my source file.
Minimum how many dimension required to export the data from FDM to HFM?
regards
Taruni

Hi,
I came to know, at least one member from the source file should be there in the integration script then only we can assign at least [None] member or any member for the target dimensions.
My source file having only 3 dimensions ( USA,Sales,Amount)
1.USA,2.Sales,3.$50000
Import Screen Dimensions:
1.Source-FM-Entity
2.Source-FDM-Account
3.Account Description
4.SourceICP
5.SourceCustom1
6.SourceCustom2
7.SourceCustom3
8.SourceCustom4
9.Amount
In the integration script its taking the values as
Source-FM-Entity(0)
Source-FDM-Account(1)
Account Description
SourceICP
SourceCustom1
SourceCustom2
SourceCustom3
SourceCustom4
Amount(2)
above it shows only 0,1,2 numbers are assigned to source dimensions.
As my source file having only 3 Dimension so it is taking only 3 dimensions shown below. rest of the dimensions it is not showing in the import screen.
*0.Source-FM-Entity,1.Source-FDM-Account,2.Amount*
If i assign any values(3-9) to next dimensions or if I left blank rs.fields("txtAcctDes") with its showing below error messages:
Error: An error occurred importing the file.
Detail: Item cannot be found in the collection corresponding to the requested name or ordinal.
At line: (39 and 42-46)
So i have assigned Source-FDM-Account Number(rs.fields(1) Value to rest of the dimensions in my integration script.
rsAppend.Fields("Account") = rs.fields(1).Value
rsAppend.Fields("Desc1") = rs.fields(1).Value
rsAppend.Fields("ICP") = rs.fields(1).Value
rsAppend.Fields("UD1") = rs.fields(1).Value
rsAppend.Fields("UD2") = rs.fields(1).Value
rsAppend.Fields("UD3") = rs.fields(1).Value
rsAppend.Fields("UD4") = rs.fields(1).Value
Now am able to import the data into import screen, And i found all the above member names as Sales as i assigned Account dimension number(1) to these members temporarily to succeed the import process . Then i have mapped to Target dimensions with [None] member combination as these members are not in original source file. Then rest of the process Export and Check is done perfectly.
*1.Am i right?? Please suggest me the correct process?*
*2.Can we use blank values in Integration Script as mentioned below??*
rsAppend.Fields("Desc1") = rs.fields("txtAcctDes").Value
rsAppend.Fields("Account") = rs.fields("txtAcct").Value
rsAppend.Fields("Entity") = rs.fields("txtCenter").Value
*1.Added value*
Example: rsAppend.Fields("Desc1") = rs.fields("1").Value
*2.Blank Value*
rsAppend.Fields("Desc1") = rs.fields("txtAcctDes").Value
*3.As per my observation system is not accepting blank values in integration script. Please correct me??*

How many SQL CAL for bpc 7.0 Microsoft

hello
customer asks how many Microsoft SQL Client Access Licenses he must buy to use SAP BPC 7.0 SP3 Microsoft (100 users).
As there is not any more direct access from Bpc client to SQL or Analysis services, I think 1 CAL is enough.
Could tell me if I'm right ?
Thanks.

David,
Don't you think your remark was rather uncharitable? It is true, there are a lot of people trying to mooch off of others' kindness (and as long as there are willing folks complying for whatever reasons, it is not going to change anytime soon), when it comes to hardcore technical details about a product, lot of people are at a loss as to how the things work (yours truly included - i have worked in SAP space for almost a decade and i couldn't tell you their licensing details - I never needed to do that to discharge my role as a functional consultant). I think Remy did indicate the thinking behind the question which is much more than a lot of folks do when they ask you and others to just e-mail some document etc....
I am sure you would concur.

How many Gb's for Vid's and Pic's?

Hi guys,
Does anyone knows how many GB's it takes per minute for a HD video on Iphone 4?
Also,how many MB it takes for a perfectly clear taken picture?
Thanks.

If your a casual user who only needs a few apps and games, and not 1000s of songs and pics, go for 16GB. IMO that is more than enough for most people.. I hav 1000 pics, 200 songs, 15 apps and still hav around 6GB left.. If you can afford 32GB though then why not

How many cert need for Lync 2013

How many cert I need to buy???
[internet] <--> [TMG] <--> [Lync edge]
[Lync front end]
is it correct to buy this two cert. (then what's the function for)
Cert 1 for TMG
Lyncrproxy.abc.com (for
Reverse Proxy???)
Meet.abc.com (for web conference)
Dailin.abc.com (for phone??)
Lyncweb.abc.com (for ???)
Lyncdiscover.abc.com (for Mobility client setup)
Cert 2 for Lync edge
Sip.abc.com (for SIP Access)
Lyncwebconf.abc.com (for Web Conferencing Edge service)
Lyncav.abc.com (for A/V service)
Thanks

You can use one cert across the Edge and Reverse Proxy as follows:-
sip.abc.com - Lync Access (use as subject name and assign to Edeg Access) (Edge)
Lyncweb.abc.com - For distribution Group and addressbook service (TMG)
dialin.abc.com - webconferencing dialin URL (TMG)
meet.abc.com - Web conferencing meet URL (TMG)
Lyncwebconf.abc.com - Web Conferencing mnedia (Edge)
lyncdiscover.abc.com - mobility (Edge)
The simplest way of requesting this cert is from the Lync Deployment Wizard on the Lync Edge Server. Be sure to marek the request as exportable so the cert can be exported from Edge and imported to TMG.

How many connection will be established when the same user wants to open 2 different application but these 2 application shares the same function module.
Thanks
Kanai

Hi,
In webdybnpro ,each Model in an Application utilizes a seperate Connection.If u create JCO connection pool for the User then while connecting to backend
1)The JCO connection pool Manager will open a new connection pool and opens the first connection.
The next available connection from the pool is allocated to the model object.
2)The model object is now able to invoke the required functionality in the ABAP system.
3) When the connection is no longer required by the application, it is returned to the pool.
4) The connection remains logged on to the backend system until either the next application
request is received, or the connection timeout is reached.
5) If no application requests arrive before the timeout is reached, the connection is flagged
for closure.
Note:-If an Application contains 2 models which are connecting to same ABAP system then second Model can be told to share the same JCo connection used by First model This is done by calling its setConnectionProvider() method.
