Hi all,
I'm trying to load a bunch of 311 NQUADS into Neo4J v.4.4.5 community in CentOS server.
I have created several files dataloadxx.cypher
call n10s.graphconfig.init({ handleVocabUris: "IGNORE"});
unwind ["output000097.nq.gz", "output000150.nq.gz", "output000203.nq.gz", "output000256.nq.gz", "output000309.nq.gz", "output000045.nq.gz", "output000098.nq.gz", "output000151.nq.gz", "output000204.nq.gz", "output000257.nq.gz", "output000310.nq.gz", "output000046.nq.gz","output000099.nq.gz", "output000152.nq.gz", "output000205.nq.gz", "output000258.nq.gz", "output000311.nq.gz"] as file
call n10s.rdf.import.fetch("file:///opt/opoceDump.nq.gz/" + file, "N-Quads", { verifyUriSyntax: false }) yield terminationStatus, triplesLoaded, triplesParsed, namespaces, extraInfo, callParams
return file, terminationStatus, triplesLoaded, triplesParsed, namespaces, extraInfo, callParams;
In a bash file, put the following:
#!/bin/bash
echo "start loading process"
"echo loading file "
dt=$(date '+%H:%M:%S');
echo ""
echo "$dt : Neo4J loading : start loading data..."
cat dataload1.cypher | cypher-shell -a neo4j://51.91.153.57:7687 --format plain
cat dataload2.cypher | cypher-shell -a neo4j://51.91.153.57:7687 --format plain
cat dataload3.cypher | cypher-shell -a neo4j://51.91.153.57:7687 --format plain
cat dataload4.cypher | cypher-shell -a neo4j://51.91.153.57:7687 --format plain
cat dataload5.cypher | cypher-shell -a neo4j://51.91.153.57:7687 --format plain
cat dataload6.cypher | cypher-shell -a neo4j://51.91.153.57:7687 --format plain
cat dataload7.cypher | cypher-shell -a neo4j://51.91.153.57:7687 --format plain
dt2=$(date '+%H:%M:%S');
echo ""
echo "$dt2 : Finished loading Neo4J data »
However, I always have an error after about 2 hours "Server no longer available".
Is there a workaround to this issue or any pointer to look at?
Thanks in advance.
