If you're having some trouble with your Java™ application, be it JSE or JEE, you've probably been looking at javacores (also called thread dumps or java dumps). If not, you should be and that is a topic for another day.   When looking at the javacores with all those threads in there, have you ever wanted to know things like: Which user is causing these threads to spawn? What were they doing in the application? When did that thread get created?   Well want no longer! With a few lines... [More]

  Sometimes, during the course of testing or troubleshooting, we need to really understand what is going on in the depths of the WebSphere code when our enterprise application executes it's logic. When the basic log output from the server does not provide enough data to surmise what the root cause of the problem is we must then collect verbose tracing data from the server in hopes to capture the sequence of events that are occurring (or not occurring) while the application is running. This is where reference traces can become... [More]

  Javascript is great, right? Well, most of the time, that is. There are those times where you want to handicap javascript a bit and limit the cookie data that it can access on your site. If you use WebSphere Application Server and you need to limit javascript access to some or all of the cookies on your site, read on...   To prevent client-side javascript from accessing cookie data on WebSphere all you need to do is create a custom property on the web container called com.ibm.ws.webcontainer.HTTPOnlyCookies .

  A StaleConnectionException is an exception that is generated by the WebSphere Application Server database connection code when a JDBC driver returns a fatal error from a connection request or operation.   Configuring a WebSphere Application Server datasource includes specifying a datasource helper class, which is selected depending on your JDBC driver type, for example, DB2UniversalDataStoreHelper for DB2, Oracle11gDataStoreHelper for Oracle 11g, etc. Each helper class contains a list of driver specific error codes...

  In my tenure with the IBM WebSphere Foundation SWAT team, I've seen many scenarios in which clients, unfortunately and for lack of a better term, shoot themselves in the foot either with the products they use or with their processes and design choices.   To bring about awareness of these scenarios, the SWAT team wrote a guide in 2009 that exposed these malpractices and explained how to mitigate them to avoid these costly mistakes, saving the business bottom-line. In 2013, we started a project to re-write the... [More]

  I wanted to take some time to explain error "J2CA0045E: Connection not available while invoking method createOrWaitForConnection (ConnectionWaitTimeoutException)." This exception occurs when your JDBC connection pool has reached the maximum number of database connections you allow, and subsequent database connection request from your application cannot be serviced before your datasource configured connection timeout value expires.   When you configure a WebSphere Application Server managed datasource, you...

  Working in WebSphere Application Server z/OS level 2, we sometimes see issues with the configuration of IBM WebSphere Application Server (WAS) OEM Edition for z/OS. Most are seen during the configuration stage to create a server instance of WAS OEM. To help save yourself some time during this process, here are a few things to check before you start this process.   SCLBDLL2 is a commonly missed library that needs to be in the system link list and APF authorized. Here is the complete list of libraries that need... [More]
