Basic questions regarding OVM for a pair of physical hosts

We have two servers available to try creating a small production-ready (Oracle supported) environment using Oracle VM. This system is for a service that my department is piloting and we're trying to do it without buying more hardware. If the initial pilot goes well then we'll improve / enhance where we need to.
We are not using Oracle VM right now and I have no experience with it, so I am hoping the forum membership can sanity-check me and answer a few questions.
Here is what we have:
* "BigGuy" - Dell R510 / Xeon X5650 / 6 cores with HT / 24 GB RAM
* "LittleGuy" - Dell R310 / Xeon X3450 / 4 cores with HT / 16 GB RAM
* We do not have a SAN, all the storage is on the physical hosts and there is plenty of it (about 1.5 TB each)
On BigGuy, we were thinking about putting:
A guest to host the production database
A guest to host the production web server
On LittleGuy, we were thinking about putting:
A guest to host the standby database
A guest to host a standby web server (this would be an image of the prod web server that we could bring up if we need to do hardware maintenance on BigGuy)
A guest to host an RMAN repository
If we have to fail over to the standy on LittleGuy then we will revert back to the primary db on BigGuy as soon as possible.
The questions:
1. In general, does this seem a reasonable approach given the nature of the project?
2. I'm confused about where we install the Oracle VM Manager. It seems like we actually need a third physical host for the VM manager and its database. However, we don't have a third machine at our disposal, so can we get by with installing it (complete with an SE database) within the Oracle VM Server running on LittleGuy?
3. Since these hosts are dissimilar, my understanding is that Live Migration won't work, but can I still run virtual machines on each physical host and manage them from the Oracle VM Manager running on LittleGuy (assuming the answer to Question 1 is Yes)? If I understand correctly, BigGuy would be in one server pool and LittleGuy would be in another. Is that correct?
Thanks,

There is no HA or Live Migration without shared storage, so you'd only be getting the benefits of generic virtualization. Also keep in mind that Oracle VM Server only provides access to completely unusued local storage, so don't create one big RAID array on your Dells, as the unused space would be unusable. Rather, create two distinct devices, one for the operating system install (which only requires 10-15GB) and another to store your virtual disk images. Also, as you intend to host database instances, I would also recommend creating physical devices for ASM storage for those instances, for the best possible performance.
2. I'm confused about where we install the Oracle VM Manager. It seems like we actually need a third physical host for the VM manager and its database. However, we don't have a third machine at our disposal, so can we get by with installing it (complete with an SE database) within the Oracle VM Server running on LittleGuy?Not easily with OVM3: there is no Oracle VM Manager template and you need Oracle VM Manager up and running to fully configure your Oracle VM Servers. Some customers have had some success creating a VirtualBox instance with Oracle VM Manager and then migrating that instance to an Oracle VM Server guest, but I haven't found a detailed how-to document on this. You could also run Oracle VM Manager as a guest of an alternatively virtualization platform (if one exists).
3. Since these hosts are dissimilar, my understanding is that Live Migration won't work, but can I still run virtual machines on each physical host and manage them from the Oracle VM Manager running on LittleGuy (assuming the answer to Question 1 is Yes)? If I understand correctly, BigGuy would be in one server pool and LittleGuy would be in another. Is that correct?The lack of shared storage makes live migration impossible anyway, so the dissimilarity between the hosts is just an additional factor that would prevent live migration were shared storage to be made available later. However, you can manage multiple physical hosts and server pools from a single Oracle VM Manager instance, so the second half of your question is correct.

Basic question regarding SSIS 2010 Package where source is Microsoft Excel 97-2005 and there is no Microsoft office or Excel driver installed in Production

Hi all,
I got one basic question regarding SSIS 2010 Package where source is Microsoft Excel 97-2005. I wanted to know How this package works in production where there is no Microsoft office or Excel driver installed. To check that there is excel driver installed
or not, I followed steps: Start-->Administrative Tools--> Data Sources(ODBC)-->Drivers and I found only 2 drivers one is SQL Server and another one is SQL Server Native Client 11.0.
Windows edition is Windows Server 2008 R2 Enterprise, Service Pack-1 and System type is 64-bit Operating System.
We are running this package from SQL Server Agent and using 32-bit (\\Machine_Name\d$\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\DTExec.exe /FILE "\\Machine_Name\d$\ Folder_Name\EtL.dtsx" /CONFIGFILE "\\Machine_Name\d$\Folder_Name\Config.dtsConfig"
/MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING E) to run this package. I opened the package and tried to find out what connection we have used and found that we have used "Excel Connection Manager" and ConnectionString=Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=F:\Fares.xls;Extended Properties="EXCEL 8.0;HDR=YES"; and source is ‘Excel Source’
I discussed with my DBA and He said that SSIS is having inbuilt Excel driver but I am not convinced.
Could anyone please clear my confusion/doubt?
I have gone through various links but my doubt is still not clear.

Thanks Shiven:) If Answer is Helpful, Please Vote

Hi S Kumar Dubey,
In SSIS, the Excel Source and Excel Destination natively use the Microsoft Jet 4.0 OLE DB Provider which is installed by SQL Server. The Microsoft Jet 4.0 OLE DB Provider deals with .xls files created by Excel 97-2003. To deal with .xlsx files created by
Excel 2007, we need the Microsoft ACE OLEDB Provider. SQL Server doesn’t install the Microsoft ACE OLEDB Provider, to get it we can install the
2007 Office System Driver: Data Connectivity Components or
Microsoft Access Database Engine 2010 Redistributable or Microsoft Office suit.
The drivers listed in the ODBC Data Source Administrator are ODBC drivers not OLEDB drivers, therefore, the Excel Source/Destination in SSIS won’t use the ODBC driver for Excel listed in it by default. On a 64-bit Windows platform, there are two versions
of ODBC Data Source Administrator. The 64-bit ODBC Data Source Administrator is C:\Windows\System32\odbcad32.exe, while the 32-bit one is C:\Windows\SysWOW64\odbcad32.exe. The original 32-bit and 64-bit ODBC drivers are installed by the Windows operating system.
By default, there are multiple 32-bit ODBC drivers and fewer 64-bit ODBC drivers installed on a 64-bit platform. To get more ODBC drivers, we can install the 2007 Office System Driver: Data Connectivity Components or Microsoft Access Database Engine 2010 Redistributable.
Besides, please note that 2007 Office System Driver: Data Connectivity Components only install 32-bit ODBC and OLEDB drivers because it only has 32-bit version, but the Microsoft Access Database Engine 2010 Redistributable has both 32- bit version and 64-bit
version.
If you have any questions, please feel free to ask.

A very basic question regarding data block

Hi All,
I've a very basic question concerning data blocks in oracle forms 10g.
I want to make a view only screen (only query allowed, no update, insert or delete).
I'll have 6-7 fields on the screen but all the fields are not from a single table.
For e.g, let say we've field names to display on the screen are f1, f2, f3, f4..
Out of this f1 and f2 will come from table A and f3, f4 will come from table B.
Now, my question : Is it possible to create a data block using the data block wizard for such situation if we select create data block from table options?
If no, can you please tell me an approach to do this.
Regards,
Navnit

Hello ,
First write your query & select datablock property.
just change the below properties
Query Data Source Type=From Clause Query
Query Data Source Name = (Paste query here)
now you should add the block ITEMs and give their names according to query columns names. shows the column on canvas and run..
Best Regard

Basic Questions related EHPs for SEM

Hi Guys,
I've some basic questions related to EHPs: -
1. If we don't mean to implement any of the new functionalities does it make any sense to implement EHP? In other words do EHPs also have some general improments other than the functionalities which can be specifically activated?
2. If we just activate a functionality and don't implement/ use it can there be any negative impact?
3. In case of a pure technical upgrade from SEM 4.0 to SEM 6.0 which EHP would be recommended?
4. Is there a quick way to find all relevant notes in EHPn which are related to corrections for EHPn-1?
Thanks in advance,
-SSC

HI,
If you see some of my older posts I have had many issues with certain features of the EHP2 functionality but that doesn't mean I would recommned against it.
BCS 6 EHPs 3 & 4 (BCS 6.03 / 6.04) - enhancement packs worth implementing?
BCS 6 EHP 2 (BCS 6.02) - activation of enhancement pack
My recommendation is to implement the EHPs but not necesarrily activate the functions (in SFW5) unless you need them - this means that you will only have to test once after EHP implementation and will have the ability to activate the other features as and when required (although testing is required after activation of course) whereas it might be difficult to persuade your client/basis team to implement EHP4 later if you don't do it now.
In the features of EHP2 (activate FIN_ACC_GROUP_CLOSE) it states that there is a general performance improvement - although I have yet to experience it! From OSS note 1171344 "The functionality which is available in EHP2 consists of...
... Performance improvements of status management, reporting and initial start-up of consolidation workbench and monitor.
Since activating FIN_ACC_GROUP_CLOSE I have had many OSS notes requiring application but i discovered that when the technical team implemented the EHPs (before i joined this client) they somehow forgot the latest SP (support packs) and didn't upgrade to the current level - so make sure that you get the right SPs too (see the links in Greg's link above) to avoid the many OSS notes.
As for your question - "is there a list of OSS notes to specific to EHP upgrades? - the answer is most definietly "NO" - I already asked OSS in desperation!
however, you can see the OSS notes that i have applied listed in the above link ( BCS 6 EHP 2 (BCS 6.02) - activation of enhancement pack )

Basic questions in SRM for Workflows+need material

Hi All,
I have developed Workflows in SAP R3.I am very new to SRM. I have following questions -
1. What is the use of BADI when we implement Workflow? My understanding till now is to provide all approvers to the
   Shooping Cart.That means for workflows without approval we dont need to BADI to implement.
2. Is there any other concepts more i have to know? Like in R3 Event will be triggered with help of change doc, status mang., LIS exceptions and all through SWEC tx. is it same in R3?
   Sorry to ask very basic questions.
   Can anyone provide me step to step guide to configure SRM workflows and Cookbook for SRM?
   My Email id is [email protected]
   It will be very helpful for me.
   Thanks in advance.
   Ashwani

Hi,
1.All the n step workflows(where approvers are determined dynamically) in SRM can be implemented only using the BADI "BBP_WFL_APPROV_BADI".the main purpose of this BADI is to fetch the Approvers/agents for the workflow.In addition to the n step WF,you also have no approval, 1 step and 2 step approval workflow in which the agent assignment can be done directly(no BADI reqd) and this is applicable for all types of business objects i.e. Shopping cart,Bid etc.For more details refer the foll link;
http://help.sap.com/saphelp_srm40/helpdata/en/17/40a86c773d6c41801d78af1a34b90f/content.htm
2.Work flow concepts are same as in R/3.So techincally you can create your custom workflows in the same way.
Do let me know if you need any further help.
BR,
Disha.
Pls reward points for useful answers.

Basic questions about Mapviewer for OBIEE 11G

Hello All..
I am pretty rookie in OBIEE and I have never worked with Mapviewer before.. I am going some POC right now in my environment and I want to experiment map reports in OBIEE.. My current OBIEE version is 11.1.1.6.5, Oracle DB version is 11.2.0.3.0 64 bit and OS is Linux 86-64 and I see that there are many versions of mapviwers to download from oracle website.
I have read a few articles on Mapviewer integration with OBIEE, but I still have a few questions about using mapviewers at the very basic level:
1. What versions do I download from Oracle website? I see there are many versions of mapviewers. Do I decide the version based on my OBIEE version or DB version?
2. What files do I download from Oracle website? I see there is mapviewer zip files and mapbuilder zip files. Which one do I download and how does installation works?
3. My OBIEE 11G and DB are running on linux environment, but in the Mapviewer download page, I don't see Oracle differentiating the OS environments. Does that mean Mapviewer is only either Unix/Linux or Windows? How do I determine in which environment I should install the files I downloaded?
I know these are very basic questions, perhaps too basic to blog about, that's why I can't find them online..
Please advise here..
Thanks

Basic questions regarding installing Forefront EP Client 2010 on Windows 2012 R2

Hi,
We have a handful of servers and client machines (although these always seem to be expanding) and as such have previously just installed the Forefront Endpoint 2010 Client manually onto the various endpoints with updates being pushed via WSUS from a Windows
2008R2 machine, without running to a full installation of SCCM or the Forefront Endpoint Server. However, trying to install the FEP 2010 client directly onto new Windows 2012R2 servers result in a "This OS is not supported" error.
After checking some articles it appears that FEP 2010 might well be supported on Win 2012R2 (and Windows 8), but only if installed via SCCM. Is this correct?
We do have access to SCCM 2012, but again I have shied away from this. I had hoped that maybe the SCCM Endpoint client could also be installed manually once more, but trying to install this on a Windows 2012R2 machine results in a "Windows compatibility
mode is not supported by this program" error.
Am I barking up the wrong tree and will I now have to finally learn and install SCCM? If so I take it that I can update my 2008R2 WSUS server to firstly Win 2012RS WSUS, then add SCCM 2012?
Cheers
Chris

Hi Joyce,
Thanks for the feedback.
Hi,
>>After checking some articles it appears that FEP 2010 might well be supported on Win 2012R2 (and Windows 8), but only if installed via SCCM. Is this correct?
According to the blog below, Forefront Endpoint Protection 2010 with Update Rollup 1
is supported on Windows Server 2012 R2.
http://blogs.technet.com/b/configmgrteam/archive/2013/09/16/support-questions-about-win-8.1-and-winsvr-2012-r2-for-configmgr-and-endpoint-protection.aspx
Please make sure you are running FEP 2010 update rollup 1. You could get it from the following link.
http://support2.microsoft.com/kb/2907566/en-us
Thanks for the feedback. I should have said that I have indeed tried this. From the initial link you posted I found the "Update Rollup 1 for Forefront Endpoint Protection 2010" (http://support2.microsoft.com/kb/2551095/en-us), however, this update
itself apparently requires a prerequisite. Whist I have tried to install the prerequisite (http://support2.microsoft.com/kb/2554364/en-us) and the Forefront Update Rollup 1 directly onto a a Windows 2012 R2 machine, I end up with errors:
Installing the Prerequisite result in a "Error code: 1642" in the log file. Have have tried to chase this error, but have not spent too much time digging as yet, but this appears to be more to do with the FEP server than the client.
Installing with the FEP Update Rollup (obviously without the prerequisite), give us three folders (FepExt, FepReport and FepUx), none of which seem to be the client per se
>>Ah, the later problem of trying to install a client from SCCM 2012 onto Windows 2012R2 maybe because I have been using SCCM 2012 SP1, and not SCCM 2012R2??
In SCCM 2012, Endpoint Protection 2012 is integrated so you cannot install FEP 2010 in it.
Best Regards,
Joyce
No no, What I meant was that I had hoped that I could install the client contained within SCCM 2012 R2 installation material manually onto a vanilla Windows 2012 R2 box (which is what I'm trying to do), in the same way that I could install the FEP 2010 on
previous Windows OS. The ISO that I have currently from our systems team is that of SCCM 2012 SP1, not SCCM 2012 R2, and the client within the SP1 package does not install in Windows 2012 R2. I'm tyring to get hold of the SCCM 2012 R2 ISO now, which (from
what I read) should allow me to manually install the client.
I may well play with SCCM later, but is a little over kill for our estate (read 10's of servers and clients, rather than 1000's), however, we should have a campus licence for SCCM.

Chris

Basic questions about programing for J9 VM

I need to create a java application to run on a Pocket PC 2003 OS and I'm limited to using IBM's Websphere J9 Virtual Machine. I'm new to using java in this capacity and therefore have lots of questions which I'm guessing are pretty basic. Despite my best efforts, I've found very little to help me online. Below are a couple questions I have that I'm hoping someone can help me with. Even better, if you know of any resources that could help me with these and other questions, I'd love to have them. Thanks in advance.
1. I'm using standard AWT for the GUI but I'm having problems getting frames, dialogs, etc., to come up in anything less then full screen. setSize() and resize() have no effect, even if I extend the frame and override the setMinimumSize, setPreferredSize, setMaximumSize methods. What do I need to do to get a child window to appear in something less than full screen?
2. I'd like to be able to add menu's to the buttom toolbar (with the keyboard) but have no idea how I would add something to it. Can someone point me in the right direction?
3. When my application gets an iconified event I go ahead and call a System.exit() to exit the application. This doesn't kill the java VM though, which continues to run in the background (taking up plenty of memory). If I run my application using the J9w.exe so that it runs without the console, then not only does the VM continue to run, but I have no way to stop it (the running program list can't see it). Since each time I run my application it starts a new VM, it only takes a couple of times before I'm out of memory and have to do a soft reset of the PDA to make things right. Can I kill the VM when I kill my application?
4. I learn best by looking at example code, but have been unable to find any code people are running on J9. I have the GolfScoreTracker installed and running on my PDA, but the jar file contains only the classes. Since it's supposed to be a demo, I had hoped that the source code would be included, is that hoping too much or is the source code available somewhere? In addition, if you know of any applications out there with available source code that are known to run well on a PocketPC J9 environment I'd appreciate the link.

Hi there, I saw your questions, im currently developing a java pocket pc application as well and here's what i go so far:
AWT seem to be hard to use on pocket pc, instead i recommend that you use SWT, which is a technology developed by eclipse. It's already installed on the eclipse plugins, you just need to download the jar and dll files for the pocket pc. They are available at: http://www.eclipse.org/downloads/index.php
I assume that you already have the J9 working on your device. So you only need to copy the SWT.jar file and the swt-win32-3064.dll to the folder containing the .class files on your device.
Now, on your java IDE(im using eclipse) Add the SWT.jar library to your project which should be on C:/eclipse/plugins/org.eclipse.swt.win32_3.0.2/ws/win32/swt.jar or something like taht depending on your eclipse root.
Now you are ready to code some SWT, here is a sample program from Carolyn MacLeod, i modified a few things so it could run on the pocket pc but it's almost the same. Once you coded in eclipse run it, then copy the class file from your desktop to your device(There should be like 4 or 5 classes like sample.class, sample$1.class etc. copy all of them) where you put the jar and dll files(If program does not run you may try to rename the dll file for swt-win32-3050.dll instead of 3064.dll). Now after you have everything set up you need to create the lnk file in order to run the program. On your desktop create a new textfile and write the following on it:
255#"\Archivos de Programa\J9\PPRO10\bin\j9w.exe" "-jcl:PPRO10" "-cp" "\My
Documents\Java\swt.jar" ;\My Documents\Java" sample
Paths depend on your install, and the place where you put your classes and jar file. path for j9w is usually "\Program Files\J9\PPRO10\bin\j9w.exe", and the last word should be the classname.
Currently this form only displays an image on a canvas, click on the browse button and choose a pic and it will display on the canvas. Im trying to connect the form to an oracle database but no success yet on the device.
Hope it helps, if you have any questions about the code or something, and I know the answer, please feel free to ask.

A basic question regarding derived class

Hi,
I am new to Java development, so this might be a very trivial question:
class Base {
public void b() {
System.out.println("Base::b() method invoked");
class Derived {
public void d() {
System.out.println("Derived::d() method invoked");
class Testing1 {
public static void main (String[] args) {
Base val = new Derived();
obj.d();
I expected this to compile ( expecting d() to be treated as a virtual function). However I get an error message : "cannot find symbol : symbol d() : location: class Base".
1. Is it possible to know where I went wrong ?
2. How can I invoked d() method from val ?
Regards,
Anirvan

two things I see are:
1. obj isn't defined anywhere
2. class derived should extend base by: class Derived extends Base

He I have a very basic question regarding reporting of invoice lines and related receiver lines

The documentation shows that receiver transaction id and receiver shipment header and line id should be joined to the same columns in AP invoice lines but these columns are not populated. What is the join for Payables and Purchasing 12.0 and beyond. We are on 12.2.4.
Please advise.

Yes, he does not want redirects because it is POF. Also, redirects don't stay in address bar (at the one I created) - once the screen loads you see the same long URL in address bar. He says I should be able to create another public name for the website (made of forms and reports). Maybe I should go with MOD_REWRITE module? I am reading about it now and they say it's more like renaming then redirecting and I think that's more like what my boss is looking for. Key question: if I use MOD_REWRITE to redirect, would the original (long) URL string be displayed once the first screen loads? I am trying to avoid that. I need users to type http://virtualserver/welcome and to STAY that way in address bar.
Thanks.

Basic question regarding c210 install

Hello,
I have installed UCS C series server and able to access CIMC. But, when I try to install ESXi vsphere, I am not able to launch virtual media from Virtual KVM console. On the console, I have this error message. Can anyone explain how to fix this issue?.
PXE-E61: Media test failure, check cable
Thanks,
Karthik.

Karthik,
Sound like you have a couple issues.
1) Unable to launch virtual media - which sounds like you've resolved if you've launched the SCU utiility. Please confirm if this is now working.
2) Issue with RAID controller. Can you detail which controller you have?
If you're using the onboard LSI controller you have the BIOSO set correctly - "SWRAID". If you're using an LSIMegaRAID controller, you'll need the BIOS setting for "Enhanced" SATA mode.

Robert

Basic question about tracking for beginner

Ok, heres the thing. I want to record multiple tracks at seperate times from the same mic in the same input, but when I go to record a second track and put that the input is track one, it will only let me record on all tracks that I have used this input for. Please help, Jeff

Hi J,
I believe is this what you need,
You just record track 1 (see channel strip on left - I/O> input 1)
when you choose track 2 (the I/O is on input 2) press and hold that button that says input 2 and change it to input 1!
(tracks 3 , 5, & 7 must be on input 1 ither)
best regards,
Jorge

Basic Questions regarding InterMedia

Hi,
I have few questions related to this Intermedia.
1. is it client-server kind of software piece? I mean will it needed to be installed on each and every user's machine?
2. Just to make sure , it's a programmatic way to do the conversion from text document (e.g. MS word) to the database. i.e. user types data in MS Word and then the Java program will be able to take care of the further processing. Right?
3. Is there different kind of API that we need to use interMedia or is it that when we have proper Oracle version it is automatically available?
Thanks-
Kirti

Kirti,
Read the interMediaOverview document
on OTN. That will answer your questions.
interMedia option is part of ORACLE 8i Server. At the time of creating the database you have to install this option.
It provides for managing (loading, retrieving, full-text search) rich data types
Text (clob/blob), Image (OrdImage), Video (OrdVideo), Audio (OrdAudio).
There are tools like Clipboard and Annotator that are part of Media Developer's kit that is downloadable from OTN.
Over 150 document formats are supported and
that includes word2000, pdf etc.
Take care
