WebLogic Integration however provides Siebel CRM and SAP R/3 connectors. http://www.bea.com/products/weblogic/integration/wli_app_intg_wp.pdf p. 36.

27 NO by default, but YES for a specialised JMX tool: ftp://edownload:[email protected]/pub/downloads/jmxmonitor.zip (on http://dev2dev.bea.com/code/samples.jsp?highlight=samples). WebLogic v7.0 ensures atomic homogeneous deployment by default (see news: weblogic.developer.interest.clustering>Atomic Homogeneous Deployment). 28 WL recommends to assign an OS DNS name to the cluster. 29 See http://e-docs.bea.com/wls/docs61/cluster/features.html#1006780. 30 Yes for v7.0 through “suspend/resume”. 31 WL will probably never implement this as it requires the server to track all downloaded client stubs and generates a huge network overhead for a simple server suspension. Instead, WL relies on a basic failover. 32 Use a custom class to implement LB: http://e-docs.bea.com/wls/docs61/ejb/reference.html#1070646 33 SLSB EJBHome calls are idempotent. See news: weblogic.developer.interest.clustering>Automatic Failover. 34 The documentation for v6.1 (nor for v7.0) does not specify the default LB algorithm and the reference for v6.1 (nor for v7.0) contains no element. Geert Lingier (BEA) answered the question.

35 Reason: idempotency is not assumed by WL for a SFSB home (arguable, but a “create” creates a dedicated instance for the client) & there is no deployment property. Note that v7.0 does allow to specify idempotency at the method level through the idempotent-methods element. 36 Reason: performance. 37 Reason: Idempotency not garanteed for SFSB EJBObject & no deployment property. (<-> v7.0) 38 Same note as for SFSB home. Take for example EJBCREATE as a non idempotent method. 39 Reason: performance. See news: weblogic.developer.interest.clustering>Automatic Failover. 40 Same reason as for RO. 41 http://e-docs.bea.com/wls/docs61//ejb/EJB_environment.html#1046391 > Entity EJBs in a Cluster 42 This requires a distributed coherent, persistent cache with bidirectional datasource synchronization decoupled from commit time. 43 Read-only cached, with timed update. 44 v7.0 implements a distributed cache with optimistic (not pessimistic) app tier locking: you cannot set cache-between-transactions to "true" in a WebLogic Server cluster when using exclusive concurrency. However, you can set this element to true when using either optimistic or readonly concurrency.” See http://e-docs.bea.com/wls/docs70/ejb/EJB_environment.html#1157072.

45 An MDB always resides on the same server as its destination. Non persistent destinations do not failover. 46 Yes for v7.0 through “suspend/resume”. 47 http://e-docs.bea.com/wls/docs61/cluster/overview.html#1004470 titles “Connection LB”, but describes random LB at the DataSource level. 48 Not “intra” as the GETCONNECTION method is not purely idempotent. 49 A DataSource is associated with exactly one ConnectionPool object, i.e.: the one on the same server node. This means that there’s no traditional LB. However, on that single server node, one could replicate the connection pool using a “MultiPool”: http://edocs.bea.com/wls/docs61/jdbc/config.html#1023894. 50 Reason is performance. See news: weblogic.developer.interest.jdbc > “Re: JDBC in a Cluster… any help please”. 51 http://www.theserverside.com/home/thread.jsp?thread_id=12095#41872 says “A similar approach has been, and still is used for the distributed JMS message factories.” 52 Same explanation as for a JDBC DataSource. 53 Load balancing occurs on ConnectionFactory.getConnection(), but this is because the connection factory itself is load balanced. Calls on a connection object are not load balanced for performance reasons. See news: weblogic.developer.interest.jdbc 04/04/2002 >Clustered JMS WLS61.1SP1” 54 Destinations will be clusterable in v7.0. Load balancing will be RR, failover not automatic. Note that messages will NOT be replicated across destination “replica’s”! This could however be implemented by a shared HA filesystem (eg. http://www.unixtools.com/veritas/).

We used a CMP deployment, except for OrderCustomerEnt and SequenceEnt. The deployment descriptors were prepared by the WebLogic performance tuning group. We made a number of corrections regarding the WLS and ECperf versions98. The server was started with 256 MB of heap (java –ms256m –mx256m). We increased the size of the thread pool associated with the default execute queue to 50 and increased ThreadPoolPercentSocketReaders to 80.

Tomcat however implements in-memory session replication by itself: see http://www.theserverside.com/resources/article.jsp?l=Tomcat.

146 Developers consider this irrelevant in the upcoming releases of JBoss v3.0, but it could be built. Implementation will handed off to JBoss CMP, hence configuration will be based on deployment descriptors (dixit Sacha Labourey). 147 Clean shutdown not available in first iteration of JBoss v3.0. However dynamic WAR updating, suspending active sessions, is available. 148 This could be built with an interceptor. 149 For all bean types: § Load Balancing: RR and First_Available are implemented. Others will come as plugins. § Automatic failover: inter-method is implemented and all metadata is available for intra-method

failover, but the feature is not yet implemented. 150 As with HTTP Session replication, these features will come in future 3.x releases. 151 This feature is under development. 152 This requires a distributed coherent, persistent cache with bidirectional datasource synchronization decoupled from commit time.

We used a total BMP deployment. This may not be optimal. Generating all deployment descriptors is out of the scope of this thesis, but may be an interesting topic of further research. The original deployment descriptors were supplied by a JBoss user Axel Becker. The server was started with 256 MB of heap (java –ms256m –mx256m).
