我必須在兩個Neo4j數據庫之間移動數據。其中一個是較舊的(2.1.8),而另一個是2.3.0。 我試過的是這個,但你也可以在輸出中看到有什麼不對。在Neo4j數據庫之間移動數據
/home/adam/neo4j-community-2.1.8/bin/neo4j-shell -path /home/adam/neo4j_bak9/ -c "dump" | /home/adam/neo4j-community-2.3.0/bin/neo4j-shell -file -
Transaction started

WARNING: Invalid input 'c': expected whitespace, comment, ';' or end of input (line 2, column 1 (offset: 39))
"create index on :`Location`(`latitude`)"

ERROR (-v for expanded information):
Transaction was marked as successful, but unable to commit transaction so rolled back.
-host Domain name or IP of host to connect to (default: localhost)
-port Port of host to connect to (default: 1337)
-name RMI name, i.e. rmi://<host>:<port>/<name> (default: shell)
-pid Process ID to connect to
-c Command line to execute. After executing it the shell exits
-file File containing commands to execute, or '-' to read from stdin. After executing it the shell exits
-readonly Connect in readonly mode (only for connecting with -path)
-path Points to a neo4j db path so that a local server can be started there
-config Points to a config file when starting a local server
Example arguments for remote:
-port 1337
-host 192.168.1.234 -port 1337 -name shell
-host localhost -readonly
...or no arguments for default values
Example arguments for local:
-path /path/to/db
-path /path/to/db -config /path/to/neo4j.config
-path /path/to/db -readonly
它看起來是Neo4j的是生產的語法,不能被新版本讀取。我做錯了什麼或者這是一個錯誤?
前段時間我創建了一個腳本,關心下載本身並執行升級:http://blog.armbruster-it.de/2012/06/upgrading-an-old-neo4j-database-using- groovy/ –
我寫了一個可以正確導出的shell擴展:https://github.com/jexp/neo4j-shell-tools#cypher-export –
將舊數據庫複製到新位置並設置allow_store_upgrade的想法是我的第一個。但是,這有問題。我通過2.1.8 - > 2.2.6 - > 2.3.0解決了它。不過,這是一件好事,一種簡單的方法來轉儲數據庫,然後加載它,而無需其他工具。原創想法看起來很有希很遺憾,由於這個小問題,這是不可能的。我希望它至少兼容2.3.0 <-> 2.3.0。 – Cob
