----------------------------------
Summary: Error running Apache Jackrabbit GarbageCollector
Key: JCR-4197
URL: https://issues.apache.org/jira/browse/JCR-4197
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: core, jackrabbit-core
Affects Versions: 2.6.4
Reporter: Prerak Tiwari
I am trying to run a GarbageCollector on my DataStore using the method given in this link : https://wiki.apache.org/jackrabbit/DataStore
public void runGC(){
LOG.info("Inside runGC() method :: START ");
DataStoreGarbageCollector gc = null;
RepositoryManager rm = null;
try {
// need to login to start the repository
rm = DMSRepositoryFactory.instance.getRepositoryFactory().getRepositoryManager((JackrabbitRepository)DMSRepositoryFactory.instance.getRepository());
session = DMSRepositoryFactory.instance.getRepository().login();
LOG.info("Inside runGC() method :: before starting Garbage Collector()");
gc = rm.createDataStoreGarbageCollector();
gc.mark();
gc.sweep();
LOG.info("Inside runGC() method :: after executing Garbage Collector()");
} catch (RepositoryException e) {
LOG.error("Error While Runining GC", e);
e.printStackTrace();
}finally {
LOG.info("Inside runGC() method :: inside finally closing Garbage Collector()");
gc.close();
}
session.logout();
rm.stop();
}
