Open CRX Sessions

[Former Community Member]

Hi,

We were see quite a number of issues within the error logs about sessions that aren't closing. I went through Adobe's article about debugging the sessions issues and we then decided to test the application over qa environment with debug enabled. We do quite a number or reverse replications and we also open sessions in case needed be but close them within the finally block. After running the application for few minutes and filtering the logs with session_analyzer jar below is the excerpt of the file. Should i be worried about it? Should i open a day care for the same? Any guidance would be appreciated.

Yes this should be a concerned. Make sure when you open a session or resourceresolver you also close it.

Its best practice to close the Session when you are done with it. For example - consider this code:
 

public String SearchCQForContent() {

try {

 //Invoke the adaptTo method to create a Session

    ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);

    session = resourceResolver.adaptTo(Session.class);

    String fulltextSearchTerm = "Geometrixx";

    // create query description as hash map (simplest way, same as form post)

    Map<String, String> map = new HashMap<String, String>();

 // create query description as hash map (simplest way, same as form post)

    map.put("path", "/content");

    map.put("type", "cq:Page");

    map.put("group.p.or", "true"); // combine this group with OR

    map.put("group.1_fulltext", fulltextSearchTerm);

    map.put("group.1_fulltext.relPath", "jcr:content");

    map.put("group.2_fulltext", fulltextSearchTerm);

    map.put("group.2_fulltext.relPath", "jcr:content/@cq:tags");

    // can be done in map or with Query methods

    map.put("p.offset", "0"); // same as query.setStart(0) below

    map.put("p.limit", "20"); // same as query.setHitsPerPage(20) below

    Query query = builder.createQuery(PredicateGroup.create(map), session);

    query.setStart(0);

    query.setHitsPerPage(20);

    SearchResult result = query.getResult();

    // paging metadata

    int hitsPerPage = result.getHits().size(); // 20 (set above) or lower

    long totalMatches = result.getTotalMatches();

    long offset = result.getStartIndex();

    long numberOfPages = totalMatches / 20;

    //Place the results in XML to return to client

    DocumentBuilderFactory factory =         DocumentBuilderFactory.newInstance();

DocumentBuilder builder = factory.newDocumentBuilder();

Document doc = builder.newDocument();

    //Start building the XML to pass back to the AEM client

    Element root = doc.createElement( "results" );

    doc.appendChild( root );

    // iterating over the results

    for (Hit hit : result.getHits()) {

           String path = hit.getPath();

            //Create a result element

            Element resultel = doc.createElement( "result" );

            root.appendChild( resultel );

            Element pathel = doc.createElement( "path" );

            pathel.appendChild( doc.createTextNode(path ) );

            resultel.appendChild( pathel );

    }

    //close the session

    session.logout();
