Guys
I have a problem with Jackrabbit Cache. I am trying to create around 10K
nodes of type "nt:file". Each of these nodes are attached with a binary file
of around 10 KB each. I am getting out of memory errors.
Below is the code
InputStream fileInputStream = new FileInputStream(f);
Node fileNode = currentNode.addNode(f.getName(), "nt:file");
Node fileNodeContent = fileNode.addNode("jcr:content",
"nt:resource");
fileNodeContent.setProperty("jcr:mimeType", "text");
fileNodeContent.setProperty("jcr:data",
session().getValueFactory().createValue(fileInputStream));
fileNodeContent.setProperty("jcr:lastModified",
session().getValueFactory().createValue(System.currentTimeMillis()));
session().save();
I have the following questions
1)How does cache mechanism work in Jackrabbit for inserts work. I try to
change the cache manager setting using example given at
http://wiki.apache.org/jackrabbit/CacheManager
It is not working because, 2nd line in this code attempt cast parent to
child. Because TransientRepository is child of Repository.
repository = new TransientRepository();
"CacheManager manager = ((RepositoryImpl) repository).getCacheManager();"
Anyone have any idea how to make this work or change the cacheManager
settings.
2) I am calling Jackrabbit from tomcat. I am thinking of increasing tomcat
jvm memory setting to increase the heap size. Is it a good idea to do that.
3) I am using one session for many of these operations. Would there be one
cache created per session?
if I have to evit the cache how can I do it? May be I evit or clean the
cache once I complete one set of operations or before going for another set
of operations.
4) Most importantly in a transient repository for creating of nodes does
cache be used? Instead of clearing cache can I clear the transient
repository? I don't know if this is possible.
Help pls?
