Altogether there are 347 init.ora parameters in Oracle Database 184.108.40.206. Looking into all documented and undocumented parameters in 220.127.116.11, we witness a high number: 2752.
18.104.22.168 does not sparkle with any fancy features and no one is expecting it to but there is one new init.ora parameter added by Oracle: awr_snapshot_time_offset.
Why is it needed? The answer is very clear in case you have a server with several databases running on it. Consolidation has been fashionable for the past decade and many scattered corporative databases have perched on the same computer.
You might have observed those spikes on the top of every hour when all the AWR snapshots are taken. How do you avoid this, i.e., say you have 12 databases on the server and you want snapshots taken on hour bases but within 5 minutes difference for every database?
Quite simply with awr_snapshot_time_offset by setting it for n*300 (seconds) for every n:th database (n = 1..12).
The documentation of awr_snapshot_time_offset gives additional details for the parameter.
And finally, here is how one can search for the values of certain parameters, for example Bloom filter related:
select a.ksppinm name, b.ksppstvl value from x$ksppi a, x$ksppcv b where a.indx = b.indx and a.ksppinm like '%bloom%';
