Run the following SQL to determine the time it failed at




where key = ‘internal.installation.state’

This will return the time that the switch failed at


Check the indexserver and nameserver trace file for an error at this particular time

The following are the most common reasons why the migration will fail

Example 1





There are several known errors related to the switching to the migrated statistic server

In the above example if you do a note search for

“exception 9002001: SQL error 129”

It will return the required note which in this case is

2036630 – statisticsserver migration fails with ‘error installing’/ ‘SQL error 129’





nameserver 2.png

In the above example if you do a note search for

“ exception 9002002: Duplicate catalog object”

It will return the required note which in this case is

2006652 – SAP HANA Statistics Server – Switch to Embedded Statistics Service fails

Example 3

if the parameter nameserver.ini [statisticsserver] active = true was revert back to “false” automatically and the migration failed

Then the note you need to refer to is

2139017 – Embedded Statistics Server migration failed while creating STARTUPMIGRATIONSTEPIMPLEMENTOR procedure

    It’s always nice to see experiences with the software to be published.

    But this blog can and should be re-worked.

    The first link URL to the SAP note goes to a SAP internal server – nobody outside the SAP network can access it.

    Also the blog is posted in your personal blog list and not at all tagged to belong to SAP HANA. That’s a good way to avoid people reading it. Either posting it directly in the SAP HANA and In-Memory Computing space or at least adding the ‘hana’ tag would help with that.

    Finally, this blog doesn’t contain a personal insight, opinion or specific experience. Therefore, the content would be better suited for a document or a WIKI page. (see e.g. Troubleshooting SAP HANA High CPU Utilisation as an example).
