Upgrade Post-Synchronize Ax 2.5 -> 3.0 Took Long time

(0) ShareShare
ReportReport
Posted on by 70

Hi All,

My company wants to upgrade ax 2.5 to 4.0, we all knew the step would be 2.5 -> 3.0 then 3.0 to 4.0

Our Platform are SQL 2000 SP 4 and Axapta 2.5 SP 2 want to upgrade Ax 3.0 SP 6 (KR1) and Ax 4.0 SP2
Our database is 140 GB, and we already shrink the data (limit the transactions) into 90 GB.

I've already done the step by step upgrade things (2.5 -> 3.0), before do the synchronize, i've upgrade the database server to sql 2005, and make the harrasment of sql 2005 (use AWE & use optimum memory). Coz Sql 2000 only have 2GB memory max.

When run the post-synchronize phase, it run batch-processing (we need to open another client axapta to process batch)

And the syntax like this "while select ..." without indexing, so it will take a lot of time for searching each record.

Previously when we use SQL2000 (it took more than 3 days) then e use SQL 2005 and it took about 22 hours.

Is there any way to optimize the data upgrade to make the process faster ?

I've already found the document how to optimize data upgrade from 3.0 to 4.0 from MBS website, but i can't find the document from 2.5 to 3.0

Any suggestions, will be very helpful.

 
Thanks before.

Cheers,

David S

    I've heard that setting the Max Degree of Parallelism to the lesser of 8 or # of physical processor cores is suggested for upgrading.

    EXEC sp_configure 'max degree of parallelism', 1;
    RECONFIGURE;
    GO
    EXEC sp_configure;

    "When SQL Server 2005 runs on a computer with more than one microprocessor or CPU, it detects the best degree of parallelism, that is, the number of processors employed to run a single statement, for each parallel plan execution. You can use the max degree of parallelism option to limit the number of processors to use in parallel plan execution. The default value of 0 uses all available processors. Set max degree of parallelism to 1 to suppress parallel plan generation. Set the value to a number greater than 1 (up to a maximum of 64) to restrict the maximum number of processors used by a single query execution. If a value greater than the number of available processors is specified, the actual number of available processors is used. If the computer has only one processor, the max degree of parallelism value is ignored."http://support.microsoft.com/kb/329204

    Hi, Thanks for the respond

    I have tried the Max DOP (degree of parallelism), The default value of Max DOP is 0 (that's mean use all available server).

    I have read the article, we have set the max dop as many as we have the physical server. Currently our server have 2 physical server ( 8 as logically). So, I set max DOP to 2.

    I run the Post-Synchronize again and it took time not different with the previous one (Max DOP set to 0)

    Any other suggestion ? Thanks before 

    Cheers,
