About gbuild and ghttp

[xqx1568]

I met a strange problem today.
When I use command bin/gbuild dbpedia201604 triples.txt to build a new db, I got the message bellow.

I think it means my biuld has some error, my db file is 4k.

When I run service by command: bin/gtttp db, the program could not listen on the port successfully.


Could you help me?

I cannot locate the problem from picture. So I can only give some suggestion. Your system memory is enough., it's not the problem.

1. In picture 1, gbuild shows that your txt file have 5 triples.

• 1. Make a file, for example t.sql.
• 2. And type in this sql: select * where {?s ?p ?o.}
• 3. bin/gquery dbpedia201604 t.sql

2. In picture 3,when you run bin/ghttp dbpedia201604, if success, you should see the words below:
   total preID num is xxx
   important pre ID is: xx xx xx
   get candidate preID...
   But I don't see it in the picture. The picture shows that the 9000 port has alraedy been acquired by ghttp. If anything goes well, the last lines you should see are:
   transaction log has been created.
   queryLog: xxx.log
   backup path: ./backups
   And if you have met these lines, open another terminal and type lsof -i:9000 to check. If my suggestion doesn't work, please send me the whole output of gbuild & ghttp to locate the problem.

I think your bin/gbuild is ok, since the program have read 198969727 triples when runing "gbuild" (line 8). The triple num: 5 is showed when inserting some statistics of your new db to system.db, it's information of your system.db, not dbpedia201604.db.
And if you want to see the size of a folder with all files in it, you need the command "du -h --max-depth=1" instead of "ls -l".

When I use ghttp, I will get this problem.
I think it is because I have used the error command ctrl-C to stop ghttp.
But whether I create a new database or reinstall gStore, this problem is always here.
Can you tell me what I can do now?

It seems that the system.db directory has some err. Try to type 'bin/ginit' to reinit the directory. If that fails, you can try deleting the entire gStore directory , not just to recompile it
