Data dump/load tool

Tool

<INSTALL_PATH>/setup/couchdb/bjornloka.jar

This tool dumps all data from CouchDB in JSON format and loads such data to the database.

Dump

java -cp bjornloka.jar jp.aegif.nemaki.bjornloka.Dump <host_address> <db_port> <repository_id> <dump_file_path> <time_stamp_flag>

host_address: for example, 127.0.0.1
db_port: for example, 5984
repository_id: for example, bedroom
dump_file_path: the path to a target file
time_stamp_flag: (optional) defaults to true. If it's false, time stamp suffix is not attached to the dump file.

So, the command will be like:
java -cp bjornloka.jar jp.aegif.nemaki.bjornloka.Dump 127.0.0.1 5984 bedroom ~/Desktop/dump

Load

java -cp bjornloka/target/bjornloka.jar jp.aegif.nemaki.bjornloka.Load <host_address> <db_port> <repository_id> <dump_file_path> <overwrite_flag>

host_address: for example, 127.0.0.1
db_port: for example, 5984
repository_id: for example, bedroom
dump_file_path: the path of a source file to load
overwrite_flag: (optional) defaults to false. If it's true, overwrite CouchDB database which has the same name as <repository_id>

So, the command will be like:
java -cp bjornloka/target/bjornloka.jar jp.aegif.nemaki.bjornloka.Load 127.0.0.1 5984 bedroom ~/Desktop/dump true

Data initialization

Load initialization data using the dump/load tool.

Initialization data are:
<INSTALL_PATH>/setup/couchdb/initial_import/bedroom_init.dump
<INSTALL_PATH>/setup/couchdb/initial_import/archive_init.dump

Main database initialization

java -cp bjornloka/target/bjornloka.jar jp.aegif.nemaki.bjornloka.Load <host_address> <db_port> <repository_id> bedroom_init.dump true

• repository_id is by default bedroom.

Archive database initialization

java -cp bjornloka/target/bjornloka.jar jp.aegif.nemaki.bjornloka.Load <host_address> <db_port> <repository_id> archive_init.dump true

• repository_id is by default archive.

Reinitializing the database

If you ever need to remove all data and come back to the state that existed after installing NemakiWare for the first time, do the following:

cd setup/couchdb
java -jar bjornloka.jar
[Answer the questions about your server, default values are good for a default install]
Import file(main):]： initial_import/bedroom_init.dump
Import file(archive):]： initial_import/archive_init.dump

Inline example: java -jar bjornloka.jar http://127.0.0.1:5984 bedroom bedroom_closet initial_import/bedroom_init.dump initial_import/archive_init.dump

Then restart NemakiWare.
