Retain SAMBA permissions while migrating from linux to solaris 10 x86

Hello,
We are migrating a system from Redhat to Solaris 10 x86 and this has brought up a question on how we can restore our SAMBA files and retain our permissions that are associated by the users name rather then their numeric ID(UID/GID). So far my research hasnt produced anything that gives a solid answer to how we do this and is it even possible.
The problem is that Windows user and group accounts are mapped locally per host by default. That mapping is defined as the accounts are referenced, so unless there is a way to guarantee the order of accounts being referenced, the mappings from Windows SIDs to Unix UIDs will be different between old and new.
If the data restoration option we choose for the new server is naive and restores only by UID and GID, the permissions in the ACLs will not map to the correct Windows accounts. We either must find a restoration option which restores permissions by name rather than ID or we must create a script which can automate pushing the ACLs into the restored filesystem correctly by name.
Initially I thought ufsdump could handle this but we are on ext3 filesystem going to vxfs. I have read a little on star but havent heard about it before. Has anyone used star for backup/restore for the purpose of retaining ACL ownership/permissions? It seems like its an old utility, maybe not used much anymore. Does anyone have a utility they have used for this purpose?
Your help is much appreciated!!

The problem is that Windows user and group accounts are mapped locally per host by default. That mapping is defined as the accounts are referenced, so unless there is a way to guarantee the order of accounts being referenced, the mappings from Windows SIDs to Unix UIDs will be different between old and new.Is there anyway that you can sanitize and post a small snippet of what's going on with the mapping files? I think I can follow this but I'm a bit confused by the username/UID thing since usually if a username is defined in /etc/passwd than the files will display the username. If a username is not defined in /etc/passwd then the ls command will revert to just showing the numbers which I take it is what you don't want to happen.
If you could also sanitize and post even one of the acl's that might help clear up that portion of the problem as well.

Migrating from Linux Mail to Exchange 2013

Is there any official documents of the Best Practices of migrating Linux Mail (Exim) to Exchange 2013?
I appreciate any help that I can receive. Thanks in advance.
My best regards.

Hi,
Basic on my research, I’m afraid that there is no tool for this kind of migration, we may need to start from PST file.
We can use Microsoft Exchange PST Capture to search for PST files on computers in your organization and then import those files to mailboxes in your organization, for your reference:
https://technet.microsoft.com/en-us/library/hh781036(v=exchg.141).aspx
Besides, I find an similar thread about Migrate Exim to Exchange:

"App_DispatcherUnhandledException" cannot work while migrating from VSTS2010 to VSTS2013

In the past, our project was developed in VSTS2010 and .NET 4.0, everything works well.
Right now, while migrating from VSTS2010 to VSTS2013 and from .NET 4.0 to .NET 4.5.1, we found that the exceptions thrown from one UI thread cannot be caught and handled in main thread.
I mean, once the exception is thrown, the "App_DispatcherUnhandledException" cannot catch and handle it in Debug.
During the migration, we don't change any codes and just update the project configuration file.
Is anyone know how to solve this problem?
Thanks so much!!

Hello Zeng Wei,
It seems we do not have an edition called VSTS2013, it is old version when in
2005. Can I just understand you are upgrade your project from Visual Studio 2010 to Visual Studio 2013?
Anyway, for App_DispatcherUnhandledException that cannot be raised, we can check the MSDN article:
https://msdn.microsoft.com/en-us/library/system.windows.application.dispatcherunhandledexception.aspx?f=255&MSPPError=-2147217396
If an exception is not handled on either a background user interface (UI) thread (a thread with its own
Dispatcher) or a background worker thread (a thread without a
Dispatcher), the exception is not forwarded to the main UI thread. Consequently,
DispatcherUnhandledException is not raised. In these circumstances, you will need to write code to do the following:
Handle exceptions on the background thread.
Dispatch those exceptions to the main UI thread.
Rethrow them on the main UI thread without handling them to allow DispatcherUnhandledException to be raised.
Another thing is that please make sure you have this code:e.Handled =
true

Barry

Problem while migrating from JSF1.1 to JSF1.2

I'm facing the following issues while migrating from WAS 6.1 to WAS7.0
For this I have upgraded Jsf 1.1 to 1.2 and webmodule to 2.5, and following errors I'm having...
1. Description     The method getExceptionMessageString(String) is undefined for the type Util
2. Description The method getMyForm(UIComponent) in the type CommandLinkRenderer is not applicable for the arguments (FacesContext, UICommand)
3. Description     The method getName() is undefined for the type HtmlBasicRenderer.Param     LinkRendererWithName.java
4. Description     The method getParamList(UIComponent) in the type HtmlBasicRenderer is not applicable for the arguments (FacesContext, UICommand)
5. Description     The method getValue() is undefined for the type HtmlBasicRenderer.Param     LinkRendererWithName.java
Any alternative methods to those above methods in JSF1.2?
or am I need to upgrade any of the jaf dependencies?
Any suggestions are appreciated.
Thanks

But you should consider implementing your Renderers only using the API and not extending the com.sun.faces.* implementation classes, or you might end up changing your code again on your next jsf updates.Hm, good thinking. I didn't think about the split between the API and the implementation.
OT question on that subject: is it really good design to have that split? JSF, JAXB, JAX-WS, even CDI has an API and an implementation part to it. But do we really need that? In the case of JSF, you have Mojarra and Myfaces (and some other obscure JSF implementation I believe). But why would you use Myfaces over Mojarra since they both solve the same problem and are both actively developed? Why do we have to deal with API/implementation conflict hell that you can often find when using JAXB, especially in a Mavenized environment? We have Weld as the implementation for CDI. What would move anyone to make a 'competing' implementation of it?
For something like JPA I can at least understand it; the persistence providers were already there before JPA saw the light of day. There was no need for Sun to create a competing implementation, so they provided the API in stead. But in all other cases... I just don't get it.

For SQL Developer version 2.1, while migrating from sybase to oracle, Using Quick migrate, during data move step, for the rows having ''(Blank) values in TEXT data type in SYBASE, which is convertd to CLOB in Oracle, the migration for that table terminates at that row.
However, NULL values in Sybase TEXT data type are successfully inserted in Oracle CLOB.
How can we overcome this?

Locale Error while migrating from One Server to another Server in Essbase

Hi Gurus,
Actually we are trying to migrate the Essbase Native users/groups from Windows 2003 Server to 2008.In windows 2003 the Version is 11.1.1 and in 2008 its 11.1.2.While Migrating i faced he below error.I was using the Migration Wizard to migrate.
Start of Application Migration.
[D4W0218G.americas.hpqcorp.net:1423.Fiji] MigrateApplication February 15, 2013 10:30:04 AM SGT Failed
Error: Source and target servers should be of same locale for migration. [Source Locale: English_UnitedStates.MS1252@Binary, Target Locale: English_UnitedStates.Latin1@Binary]
End of Application Migration.
I even tried to change the target local to source local name in Environment Variables -->ESSLANG=English_UnitedStates.MS1252@Binary but of no use.
Can anyone please suggest me how to rectify this error.
Regards,
Naveen

Hi,
Review the section beginning at page 663 on unicode applications from the Essbase Database Admin Guide. On windows this is the ESSLANG environment variable on unix there is a file that you must modify.
See http://download.oracle.com/docs/cd/E12825_01/epm.111/esb_dbag.pdf
I do suggest you read the whole section I referenced above. You would not be changing the source server. It is whatever format it is. You need to change in windows 2008.
Mark if this helps you.

Kishore Rout

"Default " problem while migrating from mysql to oracle.

I'm migrating from mysql3.23 to oracle9i via the OMWB tool.While migrating i'm getting an error message "Failed to create default for the table <table>:ora00907 missing right parenthesis".This error is due to the difference in the syntax used for the keyword "default" in mysql and oracle.In mysql we have to give after the Not Null option whereas in oracle we have to give before Not Null.
The problem is i'm migrating via the OWMB tool.Is is possible to handle this error with the help of tool itself.
Thanks
Jai.M

Jai, I'm having Frank have a look at this for you to see if we can replicate it ans help solve this issue for you. are there any issues logged on the mysql site regarding saving blobs as file?
thanks

How to resolve the encoding problem while migration from informix9.4

When I migrate the informix9.4 database, there occur a error while migrate the data from informix to oracle.
Because the source tables has a column which type is "vchar", the some row's data length more the 4000, so migration workbench convert this column type from "vchar" to "clob" automaticly. But when the worbench has created the oracle model, and then migrate the data, there occured this error:
java.io.UnsupportedEncodingException: ISO2022CN_GB
java.sql.SQLException: index miss IN or OUT param:: 9

The encode in the source informix database is "zh_CN.gbk", and the encode in the destination database is "zh_CN.gbk", why this prompt the convert error?
Another information is that excluding this table, other tables can migrated success.
So, I guess this problem must has association with the type conversation which from "vchar" to "clob", can anyone help me with this, Thanks.

Hello,
well, the limit of 4000 is clear. From the Oracle® Migration Workbench Reference Guide for Informix Dynamic Server Migrations:
VARCHAR(m,r)
The Informix Dynamic Server VARCHAR data type stores varying length single-byte and multibyte character strings of letters, numbers. and symbols. The maximum size of this column is m, that can range from 1 to 255. The minimum reserved space is r. This is optional and defaults to 0 if not specified. The minimum reserved space can range from 0 to 255.
The comparable Oracle data type is VARCHAR2(n) that also stores variable-length character strings. An Oracle VARCHAR2(n), however, can have a maximum string length of between 1 and 4000 specified for n.
Specifying a minimum reserved space is useful if the data in a row is initially small but is expected to grow at a later date. If this is the case then, when migrating Informix Dynamic Server tables that contain VARCHAR columns consider increasing the PCTFREE value in the storage clause for these tables in the Oracle database. If this column is used in an index, then the PCTFREE values for the corresponding index storage should also be considered. For indexes based on VARCHAR columns, Informix Dynamic Server allocates the maximum storage.
So it is not surprising that the workbench is converting a VARCHAR with a length of more than 4000 to a CLOB.
But that does not explain the encoding exception. This might be a problem of the Informix JDBC driver.
Is the Informix JDBC Driver Programmer's Guide helpful for you: http://publibfi.boulder.ibm.com/epubs/pdf/6435.pdf
Can you reproduce the problem with a Java program against your Informix database using your Informix JDBC driver?
Which version of Informix JDBC driver are you using?
Best regards
Wolfgang
