[jboss-jira] [JBoss JIRA] (JBNAME-51) Delay in connecting when first of multiple providers is down can cause performance issue

Delay in connecting when first of multiple providers is down can cause performance issue ---------------------------------------------------------------------------------------- Key: JBNAME-51 URL: https://issues.jboss.org/browse/JBNAME-51 Project: JBoss Naming Issue Type: Bug Components: jnpserver Affects Versions: 5.0.3.GA Reporter: Dennis Reed Assignee: Dennis Reed Fix For: 6.0.0.Beta1, 5.0.3 CP01, 5.0.6.GA Attachments: JBNAME-51.diff org.jnp.interfaces.NamingContext.checkRef always loops through the provider list in order, trying to connect to the first before checking for a cached connection to a later provider. This affects performance because it can cause a delay on every context created, waiting for a timeout on a node that is down. For instance, the following takes a very long time when node1 is down. ... env.put ( Context.PROVIDER_URL, "node1:1100,node2:1100" ); for ( int i = 0; i < 1000; ++ i ) { InitialContext ctx = new InitialContext ( env ); ... } If checkRef looked for a cached connection to any of the listed providers before trying to connect to an uncached one, there would only be a timeout delay on the very first connection attempt.
