Re: [osmosis-dev] proper usage of osmosis when writing changes to osm api db

I'm not sure if this is helpful or not

Some of this info may or may not be relevant anymore.. but

1.  If you want to load diffs, you need to make sure you load the planet
file using --slim mode (which is slower) but is required to apply diffs.

2.  This is the syntax I use.  I'm not sure why you're gzipping the
changes.osc before hand.

  2a.  download change set:
   osmosis --read-replication-interval --simplify-change
--write-xml-change
  2b.  write changeset:
   osm2pgsql --host localhost -e 10 -o expire.list --verbose
--append --slim --cache 6144 change.osc

the -e 10 and -o expire.list are optional, I use the expire list to
re-generate only tiles that are affected.

 Hi all

 I'd like to create the local copy of osm api db.
 First I populated DB with full planet.osm file using osmosis,
 afterwards initialized and created osm change file.

 Should I run --simplify-change before applying the change file to the db?

 I.e. is it required
 nice gzip -d -c change.osm.gz | nice ./osmosis --read-xml-change
 file=/dev/stdin --simplify-change --write-xml-change file=- | nice
 gzip -9 -c  change.unique.osm.gz

 Thanks

It was well intended but the original author inquired about an API DB 
database, which is populated directly by osmosis, without osm2pgsql. It 
uses a different database schema and does not have a slim mode.
