Range Extender best practices

Does anyone have any advice or resources on best practices when using a range extender?
I have a **bleep** client who has a large house. their e4200 router is one side of the house while their updstairs bedrooms are on the other side and they complain about horrible coverage.
We've tried the PLW400 and they didn't like having 2 SSIDs. So now we're trying the RE2000 and they are not thrilled about that either. I have yet to get specifics. Maybe it's too far away from the router, I dunno...
I should probably move the e4200 to a more central location in the house but there is no ethernet jacks their to connect to the modem.
So does any one else have any thoughts?

Did you check the thread on your last post (RE: e4200 and PLEK400...how to use the same SSID???)? I had made my insights on your previous post regarding the PLW400 SSID concern/problem.
Please try to check this link on how to maximizing the use of Linksys Wireless-N Range Extenders.
I would also suggest that you try to get the EA6500 or other EA series of routers. to have a more wireless range and speed, it might be an E4200 issue as well.

Best practice on extending the SIEBEL data model

Can anyone point me to a reference document or provide from their experience a simple best practice on extending the SIEBEL data model for business unique data? Basically I am looking for some simple rules - based on either use case characteristics (need to sort and filter by, need to update frequently, ...) or data characteristics (transient, changes frequently, ...) to tell me if I should extend the tables, leverage the 'x' tables, or do something else.
Preferably they would be prescriptive and tell me the limits of the different options from a use perspective.
Thanks

Accepting the given that Siebel's vanilla data model will always work best, here are some things to keep in mind if you need to add something to meet a process that the business is unwilling to adapt:
1) Avoid re-using existing business component fields and table columns that you don't need for their original purpose. This is a dangerous practice that is likely to haunt you at upgrade time, or (worse yet) might be linked to some mysterious out-of-the-box automation that you don't know about because it is hidden in class-specific user properties.
2) Be aware that X tables add a join to your queries, so if you are mapping one business component field to ATTRIB_01 and adding it to your list applets, you are potentially putting an unnecessary load on your database. X tables are best used for fields that are going to be displayed in only one or two places, so the join would not normally be included in your queries.
3) Always use a prefix (usually X_ ) to denote extension columns when you do create them.
4) Don't forget to map EIM extensions to the extension columns you create. You do not want to have to go through a schema change and release cycle just because the business wants you to import some data to your extension column.
5) Consider whether you need a conversion to populate the new column in existing database records, especially if you are configuring a default value in your extension column.
6) During upgrades, take the time to re-evalute your need for the extension column, taking into account the inevitable enhancements to the vanilla data model. For example, you may find, as we did, that the new version of the S_ADDR_ORG table had an ADDR_LINE_3 column, and our X_ADDR_ADDR3 column was no longer necessary. (Of course, re-configuring all your business components to use the new vanilla column can also be quite an ordeal.)
Good luck!

Number ranges - Import of Legacy Data - best practice

Hi,
we are planning to move legacy data objects to our SAP CRM.
These Objects have an external key (Numeric, 6 digit) in a number range that is relatively full and highly fragmented.
Is there a best practice how to implement internal number assignment for this kind of pre filled number range?
The internal key in SAP would be different and under our control, the external key is the interesting one.
Cheers,
Andreas

Hi Luís,
The scenario is in the context of insurance business.
The setup: SAP CRM as central Business Partner system. And in the CRM we keep the policy numbers of the surrounding (non SAP) policy systems as references (I'm talking about insurance policies...).
For each policy we create a one order object, containing, among others, LOB, policy type and the policy number.
These policy number ranges are to be maintained in the central CRM system in the future.
And in one of these Systems they have the situation described above:
6 digit key in a number range that is relatively full and highly fragmented. They are managing their numbers in an xls right now, but we would also have them migrated into our system.
And after the migration we would be responisble to find a unused number, whenever a new policy is to be created.
Cheers,
Andreas

Best Practice for Change Maintenance Order Number Range

Hello
We have decided that our Maintenance Orders will always start with the year of the open date. Example 201112345155
Every year we will need to change the number ranges
What is the best practice to change the order number range? What is the best approach here?
I have also another question. Why the "Current Number" is not incremental?
Thanks for the help

Hi,
The current number can be explained by use of buffering of the numbers. Buffering is defined via transaction SNRO, the AUFTRAG object is relevant for orders. When buffering is active, a set of unused numbers are assigned to each application server.
In your example - The fiirst 20 numbers were taken from the available number range and assigned to the buffer (possible 10 numbers to each of two servers). As orders are created a number is assigned from the buffer. Once the buffer values are used a further set of numbers are taken from the number range and the current number is increased (by buffer value).

HR number ranges best practice

What would be the best practice for the global organization in terms of HR records number ranges?
1. Having country specific ranges and Central person functionality to group several records when people are moved between countries
2. Having one common number range and mix up all countries in there? There would be no need to leave and re-hire if moved between countries?
Thank you for sharing your experience!

Hi,
Our NUMKR Feature looks at country, but only splits out employees from Contractors/Consultants assigning one number range for all employees and one for all contractors.
Pros are you could identify the country of the employee by looking at the personnel number without having to know the Personnel Area or other information.
Con - You would have to look at other indicators such as Company Code or Personnel Area to determine the country of assignment. You would have to change the personnel number - terminate in old country and hire in new country each time there was a change of country.

Best Practices for Integrating UC-5x0's with SBS 2003/8?

Almost all of Cisco's SBCS market is the small and medium business space. Most, if not all of these SMB's have a Microsoft Small Business Server 2003 or 2008. It will be critical, In order for Cisco to be considered as a purchase option, that the UC-5x0 integrates well into these networks.
To that end, I see a lot of talk here about how to implement parts and pieces of this, but no guidance from Cisco, no labs and no best practices or other documentation. If I am wrong, please correct me.
I am currently stumbling through and validating these configurations myself, Once complete, I will post detailed recommendations. However, it would have been nice to have a lab to follow instead of having to learn from each mistake.
Some of the challanges include;
1. Where should the UC-540 be placed: As the gateway for QOS or behind a validated UC-5x0 router/security appliance combination
2. Should the Microsoft Windows Small Business Server handle DCHP (as Microsoft's documentation says it must), or must the UC-540 handle DHCP to prevent loss of features? What about a DHCP relay scheme?
3. Which device should handle DNS?
My documentation (and I recommend that any Cisco Lab/Best Practice guidence include it as well) will assume the following real-world scenario, the same which applies to a majority of my SMB clients;
1. A UC-540 device utilizing SIP for the cost savings
2. High Speed Internet with 5 static routable IP addresses
3. An existing Microsoft Small Business Server 2003/8
4. An additional Line of Business Application or Terminal Server that utilizes the same ports (i.e. TCP 80/443/3389) as the UC-540 and the SBS, but on seperate routable IP's (Making up crazy non-standard port redirections is not an option).
5. A employee who teleworks from various places that provide a seat and a network jack, which is not under our control (i.e. a employees home, a clients' office, or a telework center). This teleworker should use the built in VPN feature within the SPA or 7925G phones because we will not have administrative access to any third party's VPN/firewall.
Your thoughs appreciated.

Progress Report;
The following changes have been made to the router in support of the previously detailed scenario. Everything appears to be working as intended.
DHCP is still on the UC540 for now. DNS is being performed by the SBS 2008.
Interestingly, the CCA still works. The NAT module even shows all the private mapped IP's, but no the corresponding public IP's. I wouldnt recommend trying to make any changes via the CCA in the NAT module.
To review, this configuration assumes the following;
1. The UC540 has a public IP address of 4.2.2.2
2. A Microsoft Small Business Server 2008 using an internal IP of 192.168.10.10 has an external IP of 4.2.2.3.
3. A third line of business application server with www, https and RDP that has an internal IP of 192.168.10.11 and an external IP of 4.2.2.4
First, backup your current configuration via the CCA,
Next, telent into the UC540, login, edit, cut and paste the following to 1:1 NAT the 2 additional public IP addresses;
ip nat inside source static tcp 192.168.10.10 25 4.2.2.3 25 extendable
ip nat inside source static tcp 192.168.10.10 80 4.2.2.3 80 extendable
ip nat inside source static tcp 192.168.10.10 443 4.2.2.3 443 extendable
ip nat inside source static tcp 192.168.10.10 987 4.2.2.3 987 extendable
ip nat inside source static tcp 192.168.10.10 1723 4.2.2.3 1723 extendable
ip nat inside source static tcp 192.168.10.10 3389 4.2.2.3 3389 extendable
ip nat inside source static tcp 192.168.10.11 80 4.2.2.4 80 extendable
ip nat inside source static tcp 192.168.10.11 443 4.2.2.4 443 extendable
ip nat inside source static tcp 192.168.10.11 3389 4.2.2.4 3389 extendable
Next, you will need to amend your UC540's default ACL.
First, copy what you have existing as I have done below (in bold), and paste them into a notepad.
Then, im told the best practice is to delete the entire existing list first, finally adding the new rules back, along with the addition of rules for your SBS an LOB server (mine in bold) as follows;

Lastly, save to memory
wr mem
One final note - if you need to use the Microsoft Windows VPN client from a workstation behind the UC540 to connect to a VPN server outside your network, and you were getting Error 721 and/or Error 800...you will need to use the following commands to add to ACL 104;
(config)#ip access-list extended 104
(config-ext-nacl)#7 permit gre any any
Im hoping there may be a better way to allowing VPN clients on the LAN with a much more specific and limited rule. I will update this post with that info when and if I discover one.
Thanks to Vijay in Cisco Tac for the guidence.

Best practice recommendation--BC set

Dear friends,
   I am using BC set concept to capture my configurations. I am a PP Consultant.
Let us consider, one scenario, Configure plant parameters in t.code OPPQ.
My requirement is:
A.   Define Floats: (Schedule Margin key)
SM key: 001
opening period: 1day
Float before prod: 2day
Float After prod: 1 day
Release period: 1 day
B.   Number range
Manitain internal number range as: 10-from:010000000999999999. (for planned orders)
This is my configuration requirement.
Method M1:
Name of the BC set: ZBC_MRP1
while creating BC set first time, while defining floats, i have wrongly captured/ activated the opening periodas 100, instead of 001. But i have correctly captured the value for number range (for my planned orders)
Now if u see the activation log for my BC set, my BC set is in "GREEN" light--Version1, successfully activated, but activated values are wrong)
So, i want to change my BC set values. Now i want to reactivate my BC set with correct value. Now i am again activating the same BC set with corret value of opening period (Value as 001 ). After reactivating the BC set, if i get into my BC set activation log, one more version (version 2) has appeared with "GREEN" light.
So in my activation log, two BC sets are visible.
If i activate Version 1---wrong values will be updated in configuration
If i activate Version 2---corrrect values will be activated in configurations
But both versions can be activated at any point of time. The latest activated version will be alwyas in top.
<b>So method 1 (M1) talks about, with one BC set name, maintain different versions of BC set.</b>...Based on your requirement activate the versions
Method 2 (M2)
Instead of creating versions within a same BC set, create one more BC set to capture new values.
So if i activate second BC set, the configuration will be updated.
Please suggest me, which method is best practice( M1 or M2)?
Thanks

I am familiar with resource bundles, but wonder if there is a better approach within
JDeveloper. Resourcebundles are the java-native way of handling locale-specific texts.
Are there any plans to enhance this area in 9.0.3? For BC4J, in 9.0.3, all control-hints and custom-validation messages (new feature) are generated in resource-bundles rather than xml-files to make it easier to "extend" for multiple locales.

SAP Functions in Detail u2013 SAP Best Practices for Chemicals
The package can also be used to support external toll processing such as that required for additional treatment or repackaging.
Tank-trailer processing u2013 In this scenario, SAP Best Practices for Chemicals helps handle the selling of bulk material, liquid or granular. It covers the process that automatically adjusts the differences between the original order quantities and the actual quantities filled in the truck. To determine the quantity actually filled, the tank trailer is weighed before and after loading. The delta weight u2013 or quantity filled u2013 is transmitted to the SAP software via an order confirmation. When the delivery for the sales order is created, the software automatically adjusts the order quantity with the confirmed filling quantity.The customer is invoiced for the precise quantity filled and delivered.
Supply Chain Planning and Execution
SAP Best Practices for Chemicals supports supply chain planning as well as supply chain execution processes:
Supply and demand planning u2013 Via the SAP Best Practices for Chemicals package, SAP enables complete support for commercial and supply-chain processes in the chemical industry, including support for integrated sales and operations planning, planning strategies for bulk material, and a variety of filling processes with corresponding packaging units.

I can't get a signal through whole house because of a brick wall What range extender do you recommend to be used with my wireless router ( apple brand)

I can't get a signal through whole house because of a brick wall What range extender do you recommend to be used with my wireless router ( apple brand)

Very few 3rd party wireless extenders will work with an Apple router, so your best bet is always to use an extender that is the same brand as the main router. An AirPort Express is a popular choice for this type of application with another Apple router.
If you had a Cisco router, then a Cisco extender would be your best bet. Same for Netgear, etc.
But......a wireless extender can only "extend" the quality of wireless signal that it receives, and not much of a wireless signal is going to make it through a brick wall, so whether any extender might do what you want is open to question.
You won't know whether an extender using wireless to connect will work to your satisfaction in your home until you actually try it out in your home.
The performance will always be much better if you can connect the extending device back to the main router using a wired Ethernet cable connection.
If it is not possible to run the Ethernet cable, a pair of Ethernet power line adapters might be able to send the signal over the existing AC power lines in your home. The theory with these devices is that you already have the wiring in place, you just need the adapters.
In practice though, things do not always work as well as the theory might suggest, so if you decide to try a pair of adapters, it might be a good idea to understand the store's return policies before you buy.

Best Practice for Significant Amounts of Data

This is basically a best-practice/concept question and it spans both Xcelsius & Excel functions:
I am working on a dashboard for the US Military to report on some basic financial transactions that happen on bases around the globe. These transactions fall into four categories, so my aggregation is as follows:
Year,Month,Country,Base,Category (data is Transaction Count and Total Amount)
This is a rather high level of aggregation, and it takes about 20 million transactions and aggregates them into about 6000 rows of data for a two year period.
I would like to allow the users to select a Category and a country and see a chart which summarizes transactions for that country ( X-axis for Month, Y-axis Transaction Count or Amount ). I would like each series on this chart to represent a Base.
My problem is that 6000 rows still appears to be too many rows for an Xcelsius dashboard to handle. I have followed the Concatenated Key approach and used SUMIF to populate a matrix with the data for use in the Chart. This matrix would have Bases for row headings (only those within the selected country) and the Column Headings would be Month. The data would be COUNT. (I also need the same matrix with Dollar Amounts as the data).
In Excel this matrix works fine and seems to be very fast. The problem is with Xcelsius. I have imported the Spreadsheet, but have NOT even created the chart yet and Xcelsius is CHOKING (and crashing). I changed Max Rows to 7000 to accommodate the data. I placed a simple combo box and a grid on the Canvas u2013 BUT NO CHART yet u2013 and the dashboard takes forever to generate and is REALLY slow to react to a simple change in the Combo Box.
So, I guess this brings up a few questions:
1)     Am I doing something wrong and did I miss something that would prevent this problem?
2)     If this is standard Xcelsius behavior, what are the Best Practices to solve the problem?
a.     Do I have to create 50 different Data Ranges in order to improve performance (i.e. Each Country-Category would have a separate range)?
b.     Would it even work if it had that many data ranges in it?
c.     Do you aggregate it as a crosstab (Months as Column headings) and insert that crosstabbed data into Excel.
d.     Other ideas that Iu2019m missing?
FYI: These dashboards will be exported to PDF and distributed. They will not be connected to a server or data source.
Any thoughts or guidance would be appreciated.
Thanks,
David

Best Practices:: How to generate XML file from a ResultSet

Hi all,
Could someone please suggest the best practices of how to generate an XML file from a resultset? I am developing a web application in Java with Oracle database and one of my tasks is to generate an XML file when the user, for example, click a "download as XML" button on the JSP. The application is basically like an Order with line items. I am using Struts and my first thought has been to have an action class which will extend struts's DownloadAction and through StAX's Iterator API to create an XML file. I intend to have a POJO which will have properties of all columns of my order and line items tables so that for each order I get all line items and:
1. Write order details then
2. Through an iterator write line items of that order to an XML file.
I will greatly appreciate for comments or suggestions on the best way to do this through any pointers on the Web.

Use a OracleWebRowSet in which an XML representation of the result set may be obtained.

Best Practice question - null or empty object?

Given a collection of objects where each object in the collection is an aggregation, is it better to leave references in the object as null or to instantiate an empty object? Now I'll clarify this a bit more.....
I have an object, MyCollection, that extends Collection and implements Serializable(work requirement). MyCollection is sent as a return from an EJB search method. The search method looks up data in a database and creates MyItem objects for each row in the database. If there are 10 rows, MyCollection would contain 10 MyItem objects (references, of course).
MyItem has three attributes:
public class MyItem implements Serializable {
    String name;
    String description;
    MyItemDetail detail;
}When creating MyItem, let's say that this item didn't have any details so there is no reason to create MyitemDetail. Is it better to leave detail as a null reference or should a MyItemdetail object be created? I know this sounds like a specific app requirement, but I'm looking for a best practice - what most people do in this case. There are reasons for both approaches. Obviously, a bunch of empty objects going over RMI is a strain on resources whereas a bunch of null references is not. But on the receiving end, you have to account for the MyItemDetail reference to be null or not - is this a hassle or not?
I looked for this at [url http://www.javapractices.com]Java Practices but found nothing.

I know this sounds like a specific apprequirement,
, but I'm looking for a best practice - what most
people do in this case. It depends but in general I use null.Stupid.Thanks for that insightful comment.

I do a lot of database work though. And for that
null means something specific.Sure, return null if you have a context where null
means something. Like for example that you got no
result at all. But as I said before its's best to
keep the nulls at the perimeter of your design. Don't
let nulls slip through.As I said, I do a lot of database work. And it does mean something specific. Thus (in conclusion) that means that, in "general", I use null most of the time.
Exactly what part of that didn't you follow?
And exactly what sort of value do you use for a Date when it is undefined? What non-null value do you use such that your users do not have to write exactly the same code that they would to check for null anyways?

Best Practices for Setting up a Windows 2012 R2 STD Domain Controller in a Remote Site

So I'm looking for an article or writeup similar to the "Adding Domain Controllers in Remote Sites" TechNet article but for Windows Server 2012 STD R2. Here is my scenario:
1. I want to setup the domain controller at Site A where the primary domain controller is located. The primary domain controller is Windows Server 2008 R2.
2. Once the DC is setup I plan on leaving it on our network for a few days before shipping it to remote Site B for installation
Other key items:
1. The remote Site B will have a different IP range than Site A but will be connected to Site A via a single VPN tunnel. All the DCs that replicate with each other are on the same domain.
2. The 2012 DC that I setup for Site B (same domain in same forest) will be a DHCP, DNS, and WSUS server all replicating to the primary DC at Site A
Questions:
1. What items can I setup while it's at Site A without effecting or conflicting with the existing network and domain controller? Can I setup a scope once the DHCP role is added?
2. All of our DCs replicate through Sites and Services, do I have to manually add this to our primary DC for the new DC going to remote Site B? Or when does this happen automatically when I promote the DC?
All and all I'm just looking for a list of Best Practices for 2012 or a Step by Step Guide. Any help would be appreciated.

Hi,
Thanks for your posting.
When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

Creating Billing Unit in CRM V1.2007 Best Practices C05

Hi,
in C05 (Org Model with HR Integration) for Best Practices V1.2007 I have to create a Billing Unit.
That means, I have to create a Corporate Account.
For Creation of the Corporate Account i need a Number Range and a Grouping.
My Question:
Maintaining Number Range and Grouping for Business Partners is described in C03.
In the Solution Builder C03 comes after C05.
So I have first to finish C03 manually via SPRO or at least I have to maintain a Number Range and a Grouping so that I´m able to create the Billing Unit as an Corporate Account and then proceed with C05?
Regards
Andreas

Hi Padma,
We are facing the same issue while installing Baseline Best practices.
"Transport numbers not fullfill the requirement"
We are trying to activate full solution.
I have already created a new work bench and customize request ,but stills its gvg "Transport numbers not fullfill the requirement".
Iam not able to find a solution for this on service market place.
Thanks & Regards,

OS X Server 3.0 new setup -- best practices?

Alright, here's what I'm after.
I'm setting up a completely new OS X Server 3.0 environment. It's on a fairly new (1.5 year old) Mac Mini, plenty of RAM and disk space, etc. This server will ONLY be used interally. It will have a private IP address such as 192.168.1.205 which will be outside of my DHCP server's range (192.168.1.10 to .199) to prevent any IP conflicts.
I am using Apple's Thuderbolt-to-Ethernet dongle for the primary network connection. The built-in NIC will be used strictly for a direct iSCSI connection to a brand new Drobo b800i storage device.
This machine will provide the following services, rougly in order of importance:
1. A Time Machine backup server for about 50 Macs running Maverics.
1a. Those networked Macs will authenticate individually to this computer for the Time Machine service
1b. This Server will get it's directory information from my primary server via LDAP/Open Directory
2. Caching server for the same network of computers
3. Serve a NetInstall image which is used to set up new computers when a new employee arrives
4. Maybe calendaring and contacts service, still considering that as a possibility
Can anyone tell me the recommended "best practices" for setting this up from scratch? I've done it twice so far and have faced problems each time. My most frequent problem, once it's set up and running, is with Time Machine Server. With nearly 100 percent consistency, when I get Time Machine Server set up and running, I can't administer it. After a few days, I'll try to look at it via the Server app. About half the time, there'll be the expected green dot by "Time Machine" indicating it is running and other times it won't be there. Regardless, when I click on Time Machine, I almost always get a blank screen simply saying "Loading." On rare occasion I'll get this:
Error Reading Settings
Service functionality and administration may be affected.
Click Continue to administer this service.
Code: 0
Either way, sometimes if I wait long enough, I'll be able to see the Time Machine server setup, but not every time. When I am able to see it, I'll have usability for a few minutes and then it kicks back to "Loading."
I do see this apparently relevant entry in the logs as seen by Console.app (happens every time I see the Loading screen):
servermgrd: [71811] error in getAndLockContext: flock(servermgr_timemachine) FATAL time out
servermgrd: [71811] process will force-quit to avoid deadlock
com.apple.launchd: (com.apple.servermgrd[72081]) Exited with code: 1
If I fire up Terminal and run "sudo serveradmin fullstatus timemachine" it'll take as long as a minute or more and finally come back with:
timemachine:command = "getState"
timemachine:state = "RUNNING"
I've tried to do some digging on these issues and have been greeted with almost nothing to go on. I've seen some rumblings about DNS settings, and here's what that looks like:
sudo changeip -checkhostname
Primary address = 192.168.1.205
Current HostName = Time-Machine-Server.local
The DNS hostname is not available, please repair DNS and re-run this tool.
dirserv:success = "success"
If DNS is a problem, I'm at a loss how to fix it. I'm not going to have a hostname because this isn't on a public network.
I have similar issues with Caching, NetInstall, etc.
So clearly I'm doing something wrong. I'm not upgrading, again, this is an entirely clean install. I'm about ready to blow it away and start fresh again, but before I do, I'd greatly appreciate any insight from others on some "best practices" or an ordered list on the best way to get this thing up and running smoothy and reliably.

Everything in OS X is dependant on proper DNS. You probably should start there. It is the first service you should be configuring and it is the most important to keep right. Don't configure any services until you have DNS straight. In OS X, DNS really stands for Do Not Skip.
This may be your toughest decision. Decide what name you want the machine to be. You have two choices.
1: Buy a valid domain name and use it on your LAN devices. You may not have a need now for use externally, but in the future when you use VPN, Profile Manager, or Web Services, at least you are prepared. This method is called split horizon DNS. Example would be apple.com. Internally you may name the server tm.apple.com. Then you may alias to it vpn.apple.com. Externally, users can access the service via vpn.apple.com but tm.apple.com remains a private address only.
2: Create an invalid private domain name. This will never route on the web so if you decide to host content for internal/external use, you may run into trouble, especially with services that require SSL certificates. Examples might be ringsmuth.int or andy.priv. These type of domains are non-routable and can result in issues of trust when communicating with other servers, but it is possible.
Once you have the name sorted out, you need to configure DNS. If you are on a network with other servers, just have the DNS admin create an A and PTR record for you. If this is your only server, then you need to configure and start the DNS service on Mavericks. The DNS service is the best Apple has ever created. A ton of power in a compact tool. For your needs, you likely need to just hit the + button and fill out the New Device record. Use a fully qualified host name in the first field and the IP address of your server (LAN address). You did use a fixed IP address and disabled the wireless card, right?
Once you have DNS working, then you can start configuring your other services. Time Machine should be pretty simple. A share point will be created automatically for you. But before you get here, I would encourage starting Open Directory. Don't do that until DNS is right and you pass the sudo changeip -checkhostname test.
