Hello experts,
just wondering if somebody already reviewed thoroughly latest guide for best practices on SAP Sybase ASE?
I am talking about the document from note 1680803 - SYB: Migration to SAP Adaptive Server Enterprise - Best Practice (former note 1722359 - SYB: Running SAP applications on SAP ASE - Best Practice).
The guide for normal runtime operation was merged with the guide for migration, but there are some contradictory statements.
Apart from that the study case is again designed for server with huge memory and lot of CPU cores (so not so real case normally, I wonder who setup so often such huge servers...), I have found some inconsistencies.
E.g. in part "Reconfigure Engines and Parallel Processing", they talk about to limit ASE engines to 16, but the command configures 32.
alter thread pool syb_default_pool with thread count = 32, idle timeout = 2000
No change to the previous setup for migration. Is this just typo? I understand it should be 16, and then also number of network tasks for normal operation would be 4 (as mentioned in the beginning of guide that normally you set up 1 per 3-4 engnes). If this is not typo, then number of network tasks is wrong as it should be 8.
Also they introduced idle timeout, but only talking about ERP and possible lower value for Solman - does this mean that for BW you keep default value (which if I am not mistaken is 100)? As per ADM540 you should even decrease this timeout when SAP system is sharing server with database - I know that document is old, but is again contradictory, not saying that it is wrong, but not well explained.
If anybody checked new version of guide, please let me know, I think it is bit messed up and is bit difficult to distinguish what you should set up for migration case and what for normal operation case.
Thanks!
Regards,
Matus
