I create a new gerrit (version: 2.13.11) using postgresql database, then I successfully migrated the H2 datas of my old gerrit (version: 2.13.11) to the new gerrit. I also executed the reindex command. but when I try to start gerrit, it failed.
This is the detail in error_log:

The both gerrit servers are running in jre7. I've no idea what should I do.
Could please give me some advice? Thank you very much!

I also have copied the git directory of old gerrit to the new gerrit.
and I did reindex successfully.
But it failed when I executed this command: bin/gerrit.sh start
I'm trying to import à CSV via Neo4JShell on Neo4J 3.0.4.
This script worked on an older version of Neo4J.
Here's my script :
USING PERIODIC COMMIT 5000
LOAD CSV WITH HEADERS FROM
"file:///my_file.csv"
AS line FIELDTERMINATOR ';'
WITH coalesce(line.VAR1,"") as var1
MERGE (i:myObject {var1: var1})
But I get this error :
WARNING: Invalid input 'S': expected 'n/N' (line 9, column 2 (offset: 247))
"USING PERIODIC COMMIT 5000"
Any idea ?
I install the zip version, one powershell to run "invoke-neo4j console", and an other powershell to run de "invoke-neo4jshell -file "my_script.cypher"
Thanks.
I want to find whether any script in one unix directory is using one particular table as "select *" or not. Means I want to find "select * from tablename". Now after select there can be any number of space or newline like "select <any number of space or newline> * <any number of space or newline> from <any number of space or newline> tablename"
Let's take this as the test file:
$ cat file
select
*
from
tablename
Using grep:
$ grep -z 'select\s*[*]\s*from\s*tablename' -- file
select
*
from
tablename
-z tells to treat the input as NUL-separated. Since no sensible text file contains NUL characters, this has the effect of reading in the whole file at once. That allows us to search over multiple lines. (If the file is too big for memory, we would want to think about another approach.) To protect against file names which begin with -, the -- is used to tell grep to stop option processing.
To obtain just the names of the matching files in the current directory:
grep -lz 'select\s*[*]\s*from\s*tablename' -- *
* tells grep to look at all files in the directory. -l tells grep to just print the names of matching files and not the matching text.
More on the need for --
Let's consider a directory with one file:
$ ls
-l-
Now, lets run a grep command:
$ grep 'regex' *
grep: invalid option -- '-'
Usage: grep [OPTION]... PATTERN [FILE]...
Try 'grep --help' for more information.
The problem here is that grep interprets the file name as two options: l and -. Since the second is not a legal option, it reports an error. To protect against this, we need to use --. The following will run without error:
grep 'regex' -- *
I found this neo4j data exporting tool (https://github.com/jexp/neo4j-shell-tools#cypher-import) and it worked perfectly on my mac OS computer. I followed the same step to export data from a ubuntu server and the following error message was generated without further explanations.
Has anyone used this tool on ubuntu and any idea what the error message may indicate? Also, is there another way to export large (~100M rows) neo4j data into a csv file?
neo4j-sh (?)$ import-cypher -d"," -o test.csv match (p:Product)-[s:SIMILAR_TO]-(q:Product) return p.Id,q.Id limit 10
Query: match (p:Product)-[s:SIMILAR_TO]-(q:Product) return p.Id,q.Id limit 10 infile (none) delim ',' quoted false outfile test.csv batch-size 1000
Error occurred in server thread; nested exception is:
java.lang.NoSuchMethodError: org.neo4j.graphdb.GraphDatabaseService.execute(Ljava/lang/String;)Lorg/neo4j/graphdb/Result;
I just added a new way of exporting data as cypher statements.
https://github.com/jexp/neo4j-shell-tools#cypher-export
(Note this is for Neo4j 2.2.5)
But for 100M rows I think import-cypher -o is still a good approach.

Supposing I have:
an Informix database named "my_database"
a table named "my_table" with the columns "col_1", "col_2" and "col_3":
I can extract the contents of the table by creating a my_table.sql script like:
unload to "my_table.txt"
select * from my_table;
and invoking dbaccess from the command line:
dbaccess my_database my_table.sql
This will produce the my_table.txt file with contents like:
value_a1|value_a2|value_a3
value_b1|value_b2|value_b3
Now, what do I have to do if I want to obtain the column names in the my_table.txt? Like:
col_1|col_2|col_3
value_a1|value_a2|value_a3
value_b1|value_b2|value_b3
Why you don't use dbschema?
To get schema of one table (without -t parameter show all database)
dbschema -d [DBName] -t [DBTable] > file.sql
To get schema of one stored procedure
dbschema -d [DBName] -f [SPName] > file.sql
None of the standard Informix tools put the column names at the top of the output as you want.
The program SQLCMD (not the Microsoft newcomer - the original one, available from the IIUG Software Archive) has the ability to do that; use the -H option for the column headings (and -T to get the column types).
sqlcmd -U -d my_database -t my_table -HT -o my_table.txt
sqlunload -d my_database -t my_table -HT -o my_table.txt
SQLCMD also can do CSV output if that's what you need (but — bug — it doesn't format the column names or column types lines correctly).
Found an easier solution. Place the headers in one file say header.txt (it will contain a single line "col_1|col_2|col_3") then to combine the header file and your output file run:
cat header.txt my_table.txt > my_table_wth_head.txt
