Hi,
We would like to shrink the data file of index server service in one of the node of a scale out hana system as it is using only 38% of total file size.
Syntax:
alter system reclaim datavolume [space] [<host_port>] <percentage_of_payload_size> <shrink_mode>
Actual Command we are planning to executing:
Instance no: 02
Data file: Belongs to slave node index server service
Hostname: host14
alter system reclaim datavolume host14:30203 120 defragment
Queries:
1. Hope this can be performed online when,
Database and application is up and running
Bw data load jobs are running
Execution of reports / queries by end users
2. What is the syntax [space] means?
3. Total size of file is 900 GB and used size is 375 GB. If we use percentage_of_payload_size - 120,
What will be the maximum space can we reclaim?
4. What will be the approximate run time of this alter statement considering the data file size mentioned above?
Regards,
Basis team.
