Move hana db from single tenant to multi tenant

Hi experts,
I have read that, for the moment, we cannot do an upgrade of a SAP system + conversion to a multi tenant Hana database in one shot. We have to deploy it on a single tenant and then move it to a multi tenant environment (where we can put a series of systems). Am I right? Right now we have a single tenant environment (A), and a multi tenant environment (B).
How can we move the database from a single tenant to a multi tenant?
- do we need to 'upgrade' the single tenant (A) to a multi tenant and then put it to our other multi tenant (B) environment? Problem here is that we then lose our single tenant environment for deploying new systems. We then need to redeploy everything, no?
- or do we just need to restore the system database to the multi tenant database?
Regards,
Kenny

Hi,
Have you changed the <sid>adm user environment variables?
You can resolve this problem using system copy procedure.
Use installation master,, export database and Instance files ..

  • Faster way to migrate from Single byte to Multi byte

    Hello,
    We are in the process of migrating from a 9i Single byte db to a 10g Multi byte db. The size of our DB is roughly 125 GB. We have fixed everything in the source database (9i) in terms of seamlessly migrating from a single byte to a multi byte db. The only issue is the migration window - curently we are doing an export/import since there is a character set migration involved and it's taking about 20+ hrs to do the import in 10g. The management wants to cut this down to less than 10 hours, if that's possible. I know the duration it takes to import depends on many factors like the system/OS configuration, SAN, etc but I wanted to know what , in theory, is considered the fastest method of migrating a database from single byte to multi byte.
    Have anybody here gone through this before?
    Thanks,
    Shaji

    If the percentage of user tables containing some convertible data (I am assuming you will not have any truncation or lossy data) is low, you can export only those tables, truncate them, and rescan the database. This should report no convertible data, except some CLOBs in Data Dictionary. Such database can be migrated to AL32UTF8 using csalter.plb. After the migration, you import only the previously exported subset of tables.
    Note, for this process to work, no convertible VARCHAR2, nor CHAR, nor LONG data can be present in the Data Dictionary.
    The process should be refined by dropping and recreating indexes on the exported tables as recreating an index is faster then updating it during import. You should also disable triggers so that they do not interfere with the migration (for example, they should not update any "last_updated" timestamp columns).
    If the number and size of affected tables is low compared to the overall size of the database, the time saved may be significant.
    There may also be tables that require even more sophisticated approach. Let's say you have a multi-gigabyte table that stores pictures or documents in a BLOB column. The table also has a single text column that keeps some non-ASCII descriptions of the stored entities. Exporting/truncating/importing such table may be still very expensive. A possible optimization is to offload the description column to an auxiliary table (together with ROWIDs), update the original column to NULL, export the auxiliary table, drop it, rescan the database, migrate with csalter.plb, re-import the auxiliary table, and restore the original column. If pictures alone occupy, for example, 30% of the whole database, such approach should yield significant time saving.

  • MDT from Single Site for Multi Domain OS Deployment

    Hi all,
    We are looking for a solution which will make it possible to use MDT from a single site to deploy Windows 7 or Windows 8 and join different domains of different customers without trust relationships between domains.
    We are a service provider which supports different customers with separate domains. At this moment those different customers have their own WDS server on site and administration is time consuming because a lot of hardware changes occur.
    We are now searching for a solution which is easier to manage and one of the solutions we are thinking about is to install a WDS server in our office and use MDT for some custom task sequences but just build one image with all the different driver packs we
    have.
    Does anyone know how to deal with this from our point of view. All tooling I can find is based on Enterprise clients with one Domain Forest and maybe some different sites but all in one domain, which makes deployment a bit easier then in our situation I guess
    as we are looking for a solution that supports Multi-domain deployment.
    Hope someone might experienced this before and can help us in the right direction. If someone has experience with additional tooling which might help us I am more then interested to know how the tooling helped in solving this.
    Preferrably we had a tool which was Multi-tenant and multiple domains could be managed from a single console, but I think that tool just doesn't exist.
    Hope someone is able to help us in the right direction. Please let me know if you have any tips or did experience the same while making a Deployment plan for the service provider you are working for.
    Many thanks in advance!

    So is the goal is not only to get multiple domains to select from, if so you could use a DomainOUList.xml file .
    Also would the clients be imaged at your site or your clients site?

  • Best Way to move MB database from single XCH 2010 to 2013 DAG

    Hi,
    We are migrating from a Single Exchange 2010 sp3 server to a 2-node exchange 2013 DAG cluster, located in another AD site.
    I can move a mailbox from 2010 to 2013 without issue, but the WAN link between 2010 and 2013 is very small.
    It will take us too long to move all mailboxes with move-mailbox over the line.
    Is there another way to move the mailboxes or Databases more quickly?
    I was thinking about copying the DB's to a physical disk from 2010 and then move and mount it on 2013. Is that even possible? I explored the possibility to seed the DB to 2013, but don't have the option to do so. 2010 is installed on 2008R2 standard.
    We prefer a short downtime and move over everthing in one go as opposed to having coeexistance for longer period of time to allow the move mailbox over the WAN to complete.
    Thanks for any suggestions.

    You can't move the databases from Exchange 2010 to Exchange 2013.
    I can think of three options.
    1.  Move the Exchange 2013 server to the same LAN as the Exchange 2010 server, move the mailboxes, then move the server back.
    2.  Move the Exchange 2010 server to the same LAN as the Exchange 2013 server and move the mailboxes.
    3.  Install a new Exchange 2010 server on the same LAN as the current Exchange 2010 server, create a DAG, add mailbox database copies on the new Exchange 2010 server, move that server to the same LAN as the Exchange 2013 server, activate the databases
    on that LAN, and then move the mailboxes.
    3a.  A variation of #3 is to build the Exchange 2010 server on the same LAN as the Exchange 2013 server and perform a manual seed of the database copies.  This is more trouble than option 3.
    Moving Exchange servers between sites is possible but there are other issues you would need to solve.  You might be best off just getting a temporary increase in your WAN link capacity for the period of the mailbox move.

  • Converting from Single Byte to Multi Byte character set

    Hello,
    I'm trying to migrate one schema, including data, from a 10g (10.1.0.2.0) DB with IW8ISO8859P8 character set, to a 10g (10.2.0.1.0) DB with AL32UTF8 character set.
    The original tables are using VARCHAR2 columns, including some VARCHAR2(1) columns.
    I'm trying to use exp and imp for the task, but during import I'm receiving errors like:
    IMP-00019: row rejected due to ORACLE error 12899
    IMP-00003: ORACLE error 12899 encountered
    ORA-12899: value too large for column "SHAMAUT"."TIKIM"."GAR_SET" (actual: 2, maximum: 1)These errors are not limited to the one-character columns only.
    Is there a way to export/import the data with AL32UTF8 in mind, so the system will automatically convert the data properly?
    Thanks for the help,
    Arie.

    It's not a true conversion problem that you have but more a space problem. Tables columns are created by default with the init. parameter NLS_LENGTH_SEMANTICS character semantics:
    If NLS_LENGTH_SEMANTICS = BYTE
    then 1 character = 1 byte whatever the db character set
    If NLS_LENGTH_SEMANTICS = CHAR
    then 1 character = 1 character size for the db character set.
    If this parameter is changed it is only taken into account for newly created tables or columns: existing columns are not changed.
    See http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96529/ch2.htm#104327
    The only solution I see is to enlarge your VARCHAR2 columns before running the import...

  • SQL pricing for Migrating an existing multi-tenant application

    We have a client with an ~10 year old multi-tenant application running on a traditional dedicated hosting environment.  The client is interested in migrating to Azure but only if they can benefit from PAAS features (managed backups, snapshots, scaling,
    etc).
    Their application automatically creates a new SQL database with each new customer signup.  As such, there are 886 databases which would need to be moved.  The total size on disk of all DBs together is only 3.82 GB.  Only 3 DBs are more than
    100 MB.  862 of the DBs are less than 10MB each (794 of those are less than 5MB).
    The way I read Azure pricing, each of these 883 DBs less than 100 GB would cost $5/month.  The only other alternative is to get a VM with SQL server on it -- but I can't see the advantage of that vs. the dedicated host they are already using.
    Is there any other alternative to consider when contemplating an application made up of many small databases?
    Thanks in advance for any advice,
    Jason

    Hi,
    If you have existing applications or workloads you simply want to grab and move to the cloud, SQL Server in a Virtual Machine is the easiest path to realize the benefits of the cloud. If you are looking to innovate and build new relational applications running
    in the cloud or extend parts of on-premises applications into the cloud, SQL Database is the best long-term solution.
    In your scenario, if use azure SQL, you must pay for each database per month, refer to
    http://azure.microsoft.com/en-us/pricing/details/sql-database/for more information about SQL Azure, cost too much.
    About use SQL VM, I suggest you read the following article.

  • Unable to send to external email recipients - Multi Tenant Exchange 2013 - MultiRole servers in DAG

    Greetings all, I hope someone can help.
    I have created a Exchange 2013 multi-tenant organization, with two servers, both multi-role - CAS and Mailbox roles.
    Internal mail flow is fine (external email addresses can send to the domain).
    External firewall port forwards ports 443 and 25 to the Internal DAG IP address.
    There are two multi-role Exchange servers that are members of the DAG.
    I am able to connect to OWA and ECP via https://externalIP/OWA and https://alias.domain.com/OWA
    No SSL certificates have been purchased or installed yet.
    Exchange URLs have not been changed since default configuration at install.
    OWA and ECP works both internal and external.
    External DNS works with SPF and PTR records correctly configured
    Exchange RCA - Send test only fails with one Spam Listing (this Blacklist provider now flags all domains and you cannot ask to be removed)
    Send Connectors are the default ones created during install. Receive connector is standard configuration with  - * - 
    When sending email to an external address, I receive a failure notice
    ServerName.test.corp.int gave this error:
    Unable to relay 
    Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept email from certain senders, or another restriction may be preventing delivery.
    More Info - 
    ServerName.test.corp.int
    Remote Server returned '550 5.7.1 Unable to relay'
    I have been troubleshooting this for many hours with no progress.
    I have created new Send Connectors for the server that is advising that it is unable to relay, but they have all failed.
    I have tried setting the Internal IP address for Exhange Server 1 (Exchange Server 2 reports failure), with most combinations of Security (Anonymous, Exchange Users, etc).
    I have also tried with the IP range 192.168.11.0/24 to allow the whole the subnet, I still receive the unable to relay failure notice.
    I have tried this guide - hxxps://glazenbakje.wordpress.com/2012/12/30/exchange-2013-how-to-configure-an-internal-relay-connector/ - with different combinations, still no resolution.
    I am at a loss as to why I can't send out with the default configuration. I would assume that email would flow out without any changes, but this does not happen.
    Can someone please assist before I lose my sanity.

    I found my one of my Exchange servers had an extra NIC. I have since added a second NIC to the other server, so now both Exchange servers have dual NICs. I removed the DAG cleanly and recreated the DAG from scratch, using this link -
    hxxp://careexchange.in/how-to-create-a-database-availability-group-in-exchange-2013/ 
    The issue still exists, even with a newly created DAG. I also found that the Tenant Address Books were not 'applied'. I applied them but still no resolution
    I think the issue is related to multi-tenant configuration even though the error says that it can't relay. The unable to relay message can appear when sending from a domain that the Organization does not support. Like trying to email as [email protected]
    when you domain name is apple.com - But through extensive research I still can't resolve the issue.

  • Interactive report: Can I exclude a particular column from single row view?

    Hi -- I posted on this yesterday (Possible to exclude interactive report column from single row display?
    a bit anxious for suggestions, I guess!
    I've added a column with edit-link functionality to my interactive report query (that is, the link
    is not attached to the database data... it's an additional column and shows an icon). It's also
    in addition to the default single row view link. (We need both.)
    Unfortunately, the Edit link column shows up in the single row view. I've pared it down as much
    as I can: the label is empty, and the null value shows as "-". But an extra row with "-" is pretty
    ugly. Is there a way to always, completely exclude this column from the single row view?
    I know I could put the edit link on a data column, but:
    1) I want the link to always be to the left of the data (and the user can re-order columns)
    2) when the user doesn't have edit privileges, the link will need to be disabled or just not
    be displayed, and I think that would be a problem if the link were on the data. (true?)
    Thanks,
    Carol

    Please disregard this thread, and the one it refers back to. I see a flaw in the design of what I was attempting to do! Creating the link for Editing as a column means the user could inadvertently not display it, or move it, or... any number of problematic scenarios.
    Thanks,
    Carol

  • What is the best format to use on an external hard drive so I can both back up my Macbook Pro and also put movies on it from another hard drive (PC)?

    I am looking for a solution to whether if it is best to get two hard drives or one that can do two things that I want.
    I am looking for a hard drive format that can both back up my 500GB Macbook Pro but I was also wondering if I could also put movies on it from another hard drive that is PC based. Would partitioning the hard drive work for this? I don't know what are the best formats to use.
    If this is too hard it might just be easier having a separate 500GB hard drive for back up of my Mac and another bigger hard drive for the movies etc (the files are probably bigger than 4GB). Any help would be greatly appreciated as I need to make a decision soon!

    Csound1 wrote:
    Microsoft has not released the official exFAT file system specification, and a restrictive license from Microsoft is required in order to make and distribute exFAT implementations. Microsoft also asserts patents on exFAT which make it impossible to re-implement its functionality in a compatible way without violating a large percentage of them.[13] This renders the implementation, distribution, and use of exFAT as a part of free or open-source operating systems or of commercial software, for which the vendors could not obtain a license from Microsoft, not only technically difficult, but legally impossible in countries that recognize United States software patents.
    Can't help with that, if one is using a Windows machine then they are subjected to their rules and control.
    Limited support outside Windows and Mac OS X operating systems as of 2012, when most consumer electronic devices could only handleFAT12/FAT16/FAT32, rendering exFAT (and flash memory formats using it) impractical as a universal exchange format.
    The OP said they plan to store movies on the external drive.
    Many movies today are well over 4GB in size, thus exFAT has to be used and formatted on the PC, which the Mac can then read.
    Older Windows NT versions up to Windows Vista without Service Pack 1 do not support exFAT.
    Irrelevant, Microsoft provides a free download of exFAT for Windows XP, and Vista shouldn't be running on pre SP1 anyway.
    Some distributions of Linux have begun to include support for exFAT. It is however, only available as a file system in user space, as it's not supported by the kernel.
    Irrelevant, OP is using Windows and OS X, not Linux and if they did Linux can read the files at least and transfer, which is all they care about really.
    Windows Vista is unable to use exFAT drives for ReadyBoost. Windows 7 removes this limitation, enabling ReadyBoost caches larger than 4 GiB.[14]
    Irrelevant, the OP's is intending to use it as transfer drive between Mac's and Windows for movies.
    The standard exFAT implementation only uses a single file allocation table and free space map. FAT file systems instead used alternating tables, as this allowed recovery of the file system if the media was ejected during a write (which occurs frequently in practice with removable media). The optional TexFAT component adds support for additional backup tables and maps, but may not be supported.
    Some relevancy, but only exFAT can handle 4GB+ files between Mac's and PC's, so the need outweighs the possible problem.
    The OP needs to follow the standard Windows practice of "safely removing hardware" before physically disconnecting the external drive. If a write is occurring, it won't allow disconnecting until the write is finished.
    Support for up to 2,796,202 files per subdirectory only.[1][nb 3] Microsoft documents a limit of 65,534 files per sub-directory for their FAT32 implementation, but other operating systems have no special limit for the number of files in a FAT32 directory. FAT32 implementations in other operating systems allow an unlimited number of files up to the number of available clusters (that is, up to 268,304,373 files on volumes without long filenames).[nb 4]
    Not a issue, only in extreme cases of a lot of small files. The OP plans to use it for movies which are usually large and take up a lot of space on the drive.
    IMMO It looks like you just ran off and copied something to argue your point when all the points are basically irrelevant.
    There is only one format that can easily share 4GB sized files between Mac's and PC's without further complications.
    It's ALSO possible to install MacDrive on the PC and format the drive on the Mac HFS+, but I didn't recommend that because I know it's a hassle just like third party NTFS writing software is a hassle on Mac's.
    If you so anti-Microsoft format, then you must know Paragon has to pay a license fee to Microsoft for using the NTFS format.
    At least with exFAT there is no fee to Redmond, at least not yet.

  • Using Migration Assistant to Move Data Files from one Account to New User

    Is it possible or recommended to use Migration Assistant to move data files from an old user account to a new user account on the same volume/hard disk?

    Migration Assitant cannot be used as a simple file transfer utility. MA can transfer an entire Home folder or entire Users folder but not individual files.
    In general files in one user account cannot be moved to another user account as this would violate built-in security measures.
    What you can do is to copy the files to an external device like a hard drive or flash drive. First log in to the old account. Then configure the drive to ignore preferences by Pressing COMMAND-I to open the Get Info window and check the Ignore permissions on this volume checkbox at the bottom of the window. Copy your files to the device. Log into the new account. Verify the external drive is still configured to ignore permissions (reset it, if not.) Copy the files from the external device into the Home folder of the new account. I would create a temporary folder for these files. If you still end up without the proper permissions you will need to make modifications that are easier done if all the files are in a single folder.
