Node Distribution: Converting scaled-out system to single-host
We have an existing sandbox system that is scaled out to 4 hosts, and we need to convert it to single-host.
We found SAP Note 2040346 where it says we need to mofify the following:
1. Adapt the table _SYS_RT.TABLE_PLACEMENT according to 1908075.
2. Use "remove host" from the Administration View in the SAP HANA Studio to unconfigure the database node that we want to remove.
What we dont understand is this phrase:
"you should use the landscape redistribution tool once the node is removed to redistribute the tables in accordance with the "new" rules in _SYS_RT.TABLE_PLACEMENT. To do this, ensure that the options "enable_merge" = true and "force_partnum_to_splitrule" = true are set in the indexserver.ini section [table_redist] before executing the plan generation."
What is landscape redistribution tool and how can we launch and use it? What is plan generation? Is there an SAP standard guide that describes the whole process of removing nodes? Please advise. Your inputs are highly appreciated. Thank you.
