Best Practice for config upgrade

Hi
Is there a best practice guide to follow to performing a network upgrade. So I am replacing a stack of 5 3750 switches and replacing with 2 stacks of 2 3750x switches, but then also introducing a 4500x vss pair aswell as the new core. Is there an easy migration process to migrate the config or do I have to understand what the current network is configured as and build a new config for the new topology.
Im new to this process so just wondering if I can find an easier way, Thanks

Is there an easy migration process to migrate the config or do I have to understand what the current network is configured as and build a new config for the new topology.
You really need to understand how the current network is configured before you can do the upgrade otherwise if something doesn't work you will have no idea of where to begin troubleshooting.
That doesn't mean you need to build an entirely new configuration because you may well be able to apply most of the configuration on your existing switches to the new switches although it's not clear what functions the new switches will be doing ie.
currently you have a stack of 3750s doing what ? eg. access for users, routing for vlans etc.
you are replacing them with 3750x's switches and 4500x switches so are you splitting up the functions of the 3750s between them.
If you are then obviously you cannot take the existing configuration and copy it to both the 3750x and the 4500x switches.
When I did upgrades like this I would download the existing configurations to my laptop and make any necessary edits. If I couldn't use the existing configuration I just created new ones. When I came to upgrade I had all the configurations ready to load onto the switches.
Bear in mind that some configuration just won't copy across ie. if you have QOS on your current switches and you try to copy that to the 4500x it probably wont work as they use different commands for a lot of the same functions.
But the key thing is you must understand what you are trying to do ie. simply trying to copy across configurations without the understanding could create a lot of problems.

SAP Best Practice For Unicode Upgrades - NetWeaver 2004s

Team SAP,
I have a customer that is starting to plan for a Unicode upgrade. The question from the customer is as follows:
What is the SAP Best Practice for Unicode Upgrades? They will be upgrading from a BW 3.5 System to NetWeaver 2004s, and their question is ... should they:
a) Perform the Unicode Upgrade At The Same Time As Their BW 3.5 > NetWeaver 2004s Upgrade, or
b) Perform NetWeaver 2004s Upgrade first, and then at a later date, perform the Unicode Upgrade?
Thank you in advance for any guidance or counsel you may be able to offer.

Best practice for R12 upgrade middle of the period

Does anyone know of where I can find an Oracle documented best practice on when to perform the 12.1.1 upgrade? We are considering if we can upgrade in the middle of a period or if we should wait until the period close.

Best practice is to read the name of a forum before you post into it.
This forum is titled: "Oracle Database General Questions."
My suspicion is your question relates to EBS.

Best practice for upgrading task definition without deleting task instances

best practice for upgrading task definition in production system without deleting or terminating task instances
If I try and update a task definition with task instances running I get the following error:
Task definition 'My Task - Add User' may not be modified while there are active task instances
Is there a best practice to handle this. I tried to force an update through the console but that didn't work. I tried editing the task from the debug page and got the same error.

1) Rename the original task definition.
2) Upload the new task definition with the original name.
3) Later, after all the running tasks have timed out, delete the old definition.
E.g., if your task definition is "myWorkflow":
1) Rename "myWorkflow" to "myWorkflow-old-2009-07-28"
2) Upload the new task definition as "myWorkflow".
Existing tasks will stay linked to the original (renamed) workflow definition.
New tasks will use the new definition.
As the previous poster notes, depending on the changes you are making, letting the old task definitions stay active could have bad side-effects and might be better avoided.

Best practice for loading config params for web services in BEA

Hello all.
I have deployed a web service using a java class as back end.
I want to read in config values (like init-params for servlets in web.xml). What
is the best practice for doing this in BEA framework? I am not sure how to use
the web.xml file in WAR file since I do not know how the name of the underlying
servlet.
Any useful pointers will be very much appreciated.
Thank you.

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.
Thanks

EP Upgrade - SP14 - Best Practice for Modification File Comparison

SDN Experts -
We are upgrading our EP from SP14 - SP16. SAP offers a file "diff" tool that is only useful for Java application files to assist in re-applying our mods on top of the new code stack.
We are looking for best practices in Portal upgrades to do the following:
- Identify all files that we have modified on existing SP
- Diff all source code files (java, XML, GUI, other) between Current SP14 and SP16
We are also looking for documentation that identifies the local directory structure for NWDS. This would aid us in creating a batch process to "diff" our source code libraries.
Any recommendations are appreciated.
Thanks

I'm not realy getting your question because you already state what to do:
We are looking for best practices in Portal upgrades to do the following:
Identify all files that we have modified on existing SP
Diff all source code files (java, XML, GUI, other) between Current SP14 and SP16
You should know by documentation what is changed I guess? Then start diff-ing the code and recompile or repackage. NWDS also has diff functionalities.
Good luck,
Benjamin

Best practices for setting up users on a small office network?

Hello,
I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
Thank you,

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.

Best practice for integrating a 3 point metro-e in to our network.

Hello,
We have just started to integrate a new 3 point metro-e wan connection to our main school office. We are moving from point to point T-1?s to 10 MB metro-e. At the main office we have a 50 MB going out to 3 other sites at 10 MB each. For two of the remote sites we have purchase new routers ? which should be straight up configurations. We are having an issue connecting the main office with the 3rd site.
At the main office we have a Catalyst 4006 and at the 3rd site we are trying to connect to a catalyst 4503.
I have attached configurations from both the main office and 3rd remote site as well as a basic diagram of how everything physically connects. These configurations are not working ? we feel that it is a gateway type problem ? but have reached no great solutions. We have tried posting to a different forum ? but so far unable to find the a solution that helps.
The problem I am having is on the remote side. I can reach the remote catalyst from the main site, but I cannot reach the devices on the other side of the remote catalyst however the remote catalyst can see devices on it's side as well as devices at the main site.
We have also tried trunking the ports on both sides and using encapsulation dot10q ? but when we do this the 3rd site is able to pick up a DHCP address from the main office ? and we do not feel that is correct. But it works ? is this not causing a large broad cast domain?
If you have any questions or need further configuration data please let me know.
The previous connection was a T1 connection through a 2620 but this is not compatible with metro-e so we are trying to connect directly through the catalysts.
The other two connection points will be connecting through cisco routers that are compatible with metro-e so i don't think I'll have problems with those sites.
Any and all help is greatly welcome ? as this is our 1st metro e project and want to make sure we are following best practices for this type of integration.
Thank you in advance for your help.
Jeff

Jeff, form your config it seems you main site and remote site are not adjacent in eigrp.
Try adding a network statement for the 171.0 link and form a neighbourship between main and remote site for the L3 routing to work.
Upon this you should be able to reach the remote site hosts.

Networking "best practice" for setting up a farm

Hi all.
We would like to set an OracleVM farm, and I have a question about "best practice" for
configuring the network. Some background:
- The hardware I have is comprised of machines with 4 gig-eth NICs each.
- The storage will be coming primarily from a backend NAS appliance (Netapp, FWIW).
- We have already allocated a separate VLAN for management.
- We would like to have HA capable VMs using OCFS2 (on top of NFS.)
I'm trying to decide between 2 possible configurations. The first would keep physical separation
between the mgt/storage networks and the DomU networks. The second would just trunk
everything together across all 4 NICs, something like:
Config 1:
- eth0 - management/cluster-interconnect
- eth1 - storage
- eth2/eth3 => bond0 - 8021q trunked, bonded interfaces for DomUs
Config 2:
- eth0/1/2/3 => bond0
Do people have experience or recommendation about the best configuration?
I'm attracted to the first option (perhaps naively) because CI/storage would benefit
from dedicated bandwidth and this configuration might also be more secure.
Regards,
Robert.

Option #4 (802.3ad) looks promising, but I don't know if this can be made to work across

Essentially, 802.3ad (also known as LACP or EtherChannel on Cisco devices) requires your switch to be properly configured to allow trunking across the interfaces used for the bond. I know that the high-end Cisco and Juniper switches do support LACP across multiple switches. In the Cisco world, this is called MEC (Multichassis EtherChannel).
If you're using low-end commodity-grade gear, you'll probably need to use active/passive bonds if you want to span switches. Alternatively, you could use one of the balance algorithms for some bandwitch increase. You'd have to run your own testing to determine which algorithm is best suited for your workload.
The Linux Foundation's Net:Bonding article has some great information on bonding in general, particularly on the various bonding methods for high availability:

What are the best practices for using the enhancement framework?

Hello enhancement framework experts,
Recently, my company upgraded to SAP NW 7.1 EhP6. This presents us with the capability to use the enhancement framework.
A couple of senior programmers were asked to deliver a guideline for use of the framework. They published the following statement:
"SAP does not guarantee the validity of the enhancement points in future releases/versions. As a result, any implemented enhancement points may require significant work during upgrades. So, enhancement points should essentially be used as an alternative to core modifications, which is a rare scenario.".
I am looking for confirmation or contradiction to the statement "SAP does not guarantee the validity of enhancement points in future releases/versions..." . Is this a true statement for both implicit and explicit enhancement points?
Is the impact of activated explicit and implicit enhancements much greater to an SAP upgrade than BAdi's and user exits?
Is there any SAP published guidelines/best practices for use of the enhancement framework?
Thank you,
Kimberly

Best practice for external but secure access to internal data?

We need external customers/vendors/partners to access some of our company data (view/add/edit). It’s not so easy as to segment out those databases/tables/records from other existing (and put separate database(s) in the DMZ where our server is). Our
current solution is to have a 1433 hole from web server into our database server. The user credentials are not in any sort of web.config but rather compiled in our DLLs, and that SQL login has read/write access to a very limited number of databases.
Our security group says this is still not secure, but how else are we to do it? Even if a web service, there still has to be a hole in somewhere. Any standard best practice for this?
Thanks.

Security is mainly about mitigation rather than 100% secure, "We have unknown unknowns". The component needs to talk to SQL Server. You could continue to use http to talk to SQL Server, perhaps even get SOAP Transactions working but personally
I'd have more worries about using such a 'less trodden' path since that is exactly the areas where more security problems are discovered. I don't know about your specific design issues so there might be even more ways to mitigate the risk but in general you're
using a DMZ as a decent way to mitigate risk. I would recommend asking your security team what they'd deem acceptable.

Best practice for migrating IDOCs?

Subject: Best practice for migrating IDOC's?
Hi,
I need to migrate some IDOC's to another system for 'historical reference'.
However, I don't want to move them using the regular setup as I don't want the inbound processing to be triggered.
The data that was created in the original system by the processed IDOC's will be migrated to the new system using migration workbench. I only need to migrate the IDOC's as-is due to legal requirements.
What is the best way to do this? I can see three solutions:
A) Download IDOC table contents to a local file and upload them in the new system. Quick and dirty approach, but it might also be a bit risky.
B) Use LSMW. However, I'm not sure whether this is feasible for IDOC's.
C) Using ALE and setting up a custom partner profile where inbound processing only writes the IDOC's to the database. Send the IDOC's from legacy to the new system. Using standard functionality in this way seems to me to be the best solution, but I need to make sure that the IDOC's once migration will get the same status as they had in the old system.
Any help/input will be appreciated
Regards
Karl Johan
PS. For anyone interested in the business case: Within EU the utility market was deregulated a few years ago, so that any customer can buy electricity from any supplier. When a customer switches supplier this is handled via EDI, in SAP using ALE and IDOC's. I'm working on a merger between two utility companies and for legal reasons we need to move the IDOC's. Any other data is migrated using migration workbench for IS-U.

Hi Daniele
I am not entirely sure, what you are asking, Please could you provide additional information.
Are you looking for best practice recommendations for Governance, for example: Change transports between DEV, QA and PRD in BPC 7.0?
What is the best method? Server Manager backup and restore, etc ?
And
Best Practice recommendations on how to upgrade to a different version of BPC, for example: Upgrading from BPC 7.0 to 7.5 or 10.0 ?

Best practice for distributing/releasing J2EE applications.

Hi All,
We are developing a J2EE application and would like some information on the best
practices to be followed for distributing/releasing J2EE applications, in general.
In particular, the dilemma we have is centered around the generation of stub, skeleton
and additional classes for the application.
Most App. Servers can generate the required classes while deploying the EJBs in the
application i.e. at install time. While some ( BEA Weblogic and IBM Websphere are
two that we are aware of ) allow these classes to be generated before the installation
time and the .ear file containing the additional classes is the one that is uploaded.
For instance, say we have assembled the application "myapp.ear" . There are two ways
in which the classes can be generated. The first is using 'ejbc' ( assume we are
using BEA Weblogic ), which generates the stub, skeleton and additional classes for
the application and returns the file, say, "Deployable_myapp.ear" containing all
the necessary classes and files. This file is the one that is then installed. The
other option is to install the file "myapp.ear" and let the Weblogic App. server
itself, generate the required classes at the installation time.
If the first way, of 'pre-generating' the stubs is followed, does it require us to
separately generate the stubs for each versions of the App. Server that we support
? i.e. if we generate a deployable file having the required classes using the 'ejbc'
of Weblogic Ver5.1, can the same file be installed on Weblogic Ver6.1 or do we
have to generate a separate file?
If the second method, of 'install-time-generation' of stubs is used, what is the
nature/magnitude of the risk that we are taking in terms of the failure of the installation
Any links to useful resources as well as comments/suggestions will be appreciated.
TIA
Regards,
Aasif

Its much easier to distribute schema/data from an older version to a newer one than the other way around. Nearly all SQL Server deployment features supports database version upgrade, and these include the "Copy Database" wizard, BACKUP/RESTORE,
detach/attach, script generation, Microsoft Sync framework, and a few others.
EVEN if you just want to distribute schemas, you may want to distribute the entire database, and then truncate the tables to purge data.
Backing up and restoring your database is by far the most RELIABLE method of distributing it, but it may not be pratical in some cases because you'll need to generate a new backup every time a schema change occurs, but not if you already have an automated
backup/maintenance routine in your environment.
As an alternative, you can Copy Database functionality in SSMS, although it may present itself unstable in some situations, specially if you are distributing across multiple subnets and/or domains. It will also require you to purge data if/when applicable.
Another option is to detach your database, copy its files, and then attach them in both the source and destination instances. It will generate downtime for your detached databases, so there are better methods for distribution available.
And then there is the previously mentioned method of generating scripts for schema, and then using an INSERT statement or the import data wizard available in SSMS (which is very practical and implements a SSIS package internally that can be saved for repeated
executions). Works fine, not as practical as the other options, but is the best way for distributing databases when their version is being downgraded.
With all this said, there is no "best practice" for this. There are multiple features, each offering their own advantages and downfalls which allow them to align to different business requirements.

Best practice for mouseless ADF applications

I am developing an ADF application where the users do not want to use the mouse.
So I would like to know if there are a best practice for this?
I am already using the accessKey functionality and subforms defaultCommand
But I have had problems setting focus to objects on a page like tables. I would like a button to return the focus to the table after it has made the command like delete.
I have implemented a solution where I have found inspiration several threads and other webpages (see below).
Is this solution okay?
Are there any problems with it?
I would also like to know if there are better pathways to go like

Hi,
I am developing an ADF application where the users do not want to use the mouse. So I would like to know if there are a best practice for this?
Well HTML (and this is the user interface you see) follows a tab index navigation that you follow with "tab" and "shift+tab". Anything else is a short cut for which you use mnemonics (as you already do) or shortcuts (explained in http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html). There is a distinction to make between non-web environments (which I think you and your users have abackground in) and client desktop environments. Browsers block some keyboard functionality for their own purpose. So you may have to find a list of keys first that work across browsers. Unlike desktop clients, which allow you to "press a button" without the button to take focus, this cannot be done on the web. So you need to be clever here, avoiding buttons at all.
The following paper is about JavaScript in ADF and explains the basics for what Chris Muir explains in : http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html
http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf
It has the outline for how to register short cut keys that perform a specific action (e.g. register ctrl+d to delete the current row you are on, or press F11 to execute a query (similar to Oracle Forms frmres files)). However, be aware that this includes some code you have to write (actually quite some code to be honest).
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/79-global-template-button-strategy-360139.pdf (are there an example implementation?), or
http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html
Actually these are implementations as they come with example code for you to use and customize, do they? So what is this question asking for more ? Also note that global buttons don't quite have anything in common with the question you asked. I assume you want to see it as an implementation of the Forms toolbar that operates on the form or table the focus is in. This however does not work for the web as there is nothing that keeps track of which component has a focus and to what iterator (data block) it belongs. This would involve even more coding (though possibly doable)

What are best practice for packaging and deploying j2EE apps to iAS?

We've been running a set of J2EE applications on a pair of iAS SP1b for about a year and it has been quite stable.
Recently however we have had a number of LDAP issues, particularly when registering and unregistering applications (registering ear files sometimes fails 1st time but may work 2nd time). Also We've noticed very occasionally that old versions of classes sometimes find their way onto our machines.
What is considered to be best practice in terms of packaging and deployment, specifically:
1) Packaging - using the deployTool that comes with iAS6 SP1b to package is a big manual task, especially when you have 200+ jsp files. Are people out there using this or are they scripting it with a build tool such as Ant?
2) Deploying an existing application to multiple iAS's. Are you guys unregistering old application then reregistering new application? Are you shutting down iAS whilst doing the deployment?
3) Deploying ear files can take 5 to 10 mins, is this normal?
4) In a clustered scenario where HTTPSession is shared what are the consequences of doing deployments to data stored in session?
thanks in asvance for your replies

You may want to consider upgrading your application server environment to a newer service pack. There are numerous enhancements involving the deployment tool and run time layout of your application that make clear where you're application is loading its files from.
If you've at a long running application server environment, with lots of deployments under your belt, you might start to notice slow downs in deployment and kjs start time. Generally this is due to garbage collecting in your iAS registry.
You can do several things to resolve this. The most complete solution is to reinstall the application server. This will guarantee a clean ldap registry. Of course you've got to restablish your configurations and redeploy your applications. When done, backup your application server install space with the application server and directory server off. You can use this backup to return to a known configuation at some future time.
For the second method: <B>BE CAREFUL - BACKUP FIRST</B>
There is a more exhaustive solution that involves examining your deployed components to determine the active GUIDS. You then search the NameTrans section of the registry searching for Applogic Servlet *, and Bean * entries that represent your previously deployed components but are represented in the set of deployed GUIDs. Record these older GUIDs, remove them from ClassImp and ClassDef. Finally remove the older entries from NameTrans.
Best practices for deployment depend on your particular environmental needs. Many people utilize ANT as a build tool. In later versions of the application server, complete ANT scripts are included that address compiling, assembly and deployment. Ant 1.4 includes iAS specific targets and general J2EE targets. There are iAS specific targets that can be utilized with the 1.3 version. Specialized build targets are not required however to deploy to iAS.
Newer versions of the deployment tool allow you to specify that JSPs are not to be registered automatically. This can be significant if deployment times lag. Registered JSP's however benefit more fully from the services that iAS offers.
2) In general it is better to undeploy then redeploy. However, if you know that you're not changing GUIDs, recreating an existing application with new GUIDs, or removing registered components, you may avoid the undeploy phase.
If you shut down the KJS processes during deployment you can eliminate some addition workload on the LDAP server which really gets pounded during deployment. This is because the KJS processes detect changes and do registry loads to repopulate their caches. This can happen many times during a deployment and does not provide any benefit.
3) Deploying can be a lengthy process. There have been improvements in that performance from service pack to service pack but unfortunately you wont see dramatic drops in deployment times.
One thing you can do to reduce deployment times is to understand the type of deployment. If you have not manipulated your deployment descriptors in any way, then there is no need to deploy. Simply drop your newer bits in to the run time space of the application server. In later service packs this means exploding the package (ear,war, or jar) in to the appropriate subdirectory of the APPS directory.
4) If you've changed the classes of objects that have been placed in HTTPSession, you may find that you can no longer utilize those objects. For that reason, it is suggested that objects placed in session be kept as simple as possible in order to minimize this effect. In general however, is not a good idea to change a web application during the life span of a session.
