How to Identify Class Loader Synchronization Performance Bottlenecks in AIX, Linux and Windows

MicheleCalcavecchia 270000HCF1 | | Visits (471)

Tweet
    Class loader synchronization bottlenecks are common problems brought to the attention of WebSphere Application Server L2 Support by our clients.  This is a common type of performance problem called a livelock where many threads are contending on a set of locks. The performance overhead is proportional to the lock contention, so the problem might not show up in a test environment with a low number of concurrent requests, or patterns of requests which aren't exercising the lock at the same time.  From the viewpoint of...

java.lang.ClassNotFoundException: [Ljava.lang.String; after updating to Java 8.0.5.5 or later

DougSpath 1000009TXW | | Visits (811)

Tweet
  After updating WebSphere's SDK to Java 8 SR5 FIx Pack 5 (8.0.5.5) or later, some clients started getting an error in their SystemOut.log: "java.lang.ClassNotFoundException: [Ljava.lang.String;"   The solution is to add a Generic JVM argument of: -Dsun.lang.ClassLoader.allowArraySyntax=true   The behavior in Java 8.0.5.0 and earlier is incorrect, because it shouldn't be possible to load array classes in this way. In fact, array classes are never "loaded" at all - they are created automatically as... [More]

WebSphere eXtreme Scale (WXS) monitoring minimum recommendations

Eli_Lippard 0600022DVH | | Visits (1199)

Tweet
  The WebSphere eXtreme Scale (WXS) product documentation has a section on monitoring that details all the monitoring options.   However, the documentation in the Knowledge Center does not provide details of what specifically needs to be monitored and how to interpret the results. Thus, in support we are often asked “What should we monitor in WXS to determine the health of the environment?” Normally this question is in regards to environmental stability or determining the status of the environment after container start or...

  I would like to talk about the every popular and common features of TWSearch and saved searches for IBM Business Process Manager (BPM).   Searching! Searching for instances and tasks is a common operation in IBM BPM. Three common methods are with the TWSearch JS API ( example 2 ), exposed saved search , and the REST API searches ( saved search and query ). Something we see in Support is "How and why are my searches taking a long time?" Sometimes the performance issue is the query itself and how the query... [More]

Key Features and Troubleshooting Tips for Corrupted IBM Installation Manager Agent Data and IMShared Issues

Qing Ayers 270007BSET | | Visits (2431)

Tweet
  IBM Installation Manager (IM) is used to install IBM products such as WebSphere Application Server (WAS) v8.x. Once you use IM to install WAS v8.0 or above, you must maintain IM’s agent data and IMShared in good shape, or there would be an issue once you plan to upgrade WAS to a higher fixpack level, install other products on top of WAS, or downgrade WAS later.   These are the design features of using Installation Manager (IM): - IM can be used to install individual software packages on your local machine, or in conjunction...

What You May Want to Know About Copying Assets Between Different Tracks

YuanShang 27000723E1 | | Visits (1764)

Tweet
  If you are a Business Process Manager (BPM) system administrator or developer, you have probably known about the function of "Copy" assets from one track to another at Process Center and Eclipse Process Designer for a long time. We offered this function to enable our users to take advantages of multiple tracks, in other words, generating splitting workspaces for developers to work in isolation. You could always have different tracks under the same project or process application, and after separate development and testing, this... [More]

YuanShang 27000723E1 | | Visits (2508)

Tweet
  We often get this question in Business Process Manager (BPM) support: "How do we get a list of bpd instances or tasks for a particular snapshot?" When it comes to application and snapshot management, it’s a very common question that each BPM system administrator may encounter. Therefore, a tool or method which can be used to simply query and customize the results, is always one of the top requirements we have received from our clients. In this article, we will cover some basic tools and steps that we recommend you use... [More]

How to complete the ownerless task in BPM

JinShang 110000EPES | | Visits (2416)

Tweet
  In Business Process Mananger (BPM) process, some clients use the team filter service to assign certain users to an activity. When the process is running on the production environment, only the specific users are qualified to claim the tasks. If the authorized users are not available to deal with the tasks, for example if the users have left the company, how can you deal with the 'ownerless' tasks in BPM? In this blog entry, I will introduce one solution to handle the situation and move the process forward.   Let's talk... [More]

BPM - Instances Cleanup Strategy in Constrained Situations

SmithaVenugopal 060001159S | | Comment (1) | Visits (3532)

Tweet
  The running of business processes and services in IBM Business Process Manager (BPM) involves persisting data in multiple tables in different cardinalities in the BPM Process Server schema (assuming Oracle as the database in this blog) including the persistence of the process instances, tasks, variables etc. Once these processes are completed or terminated, the data is of little use to the functional needs of the business. At a given point in time, a process can assume the following states Active-1 Failed -3 Suspended -6 Terminated -4... [More]

Java SE8 - WebSphere V855 vs V9

Ajay Bhalodia 060000V8BJ | | Visits (3872)

Tweet
  Both WebSphere Application Server (WAS) V855x and V9 support Java Standard Edition 8 (Java SE 8). However, the installation images required for both are different and unique:   For WAS V855x, the Java SE8 is optionally supported. In order to use Java SE 8 for WAS you need to download the recommended Java SE 8 fixpack build that is made available with the WAS fixpack. The WAS fixpack page will provide a link for the Java SE 8 fixpack that is made available for installation with the WAS fixpack. The Java SE 8 fixpack can then be... [More]

Tips to shorten the processing time of "Migrating inflight data"

Yan Fang 1200008V6D | | Visits (3919)

Tweet
  I have had several instances lately where clients either from IBM Business Process Manager (BPM) 8.5.* or from IBM Business Process Manager 8.0.* said that it takes a very long time to complete migrating inflight data's process. For example, in one case, it took about 4 hours to finish instance migration (the number of migrations was just about 60,000). It is too slow, right? Let me first give you some background knowledge for why you would do instance migration. Often, clients need to make changes to their applications and deploy... [More]

WebSphere eXtreme Scale (WXS) Load Distribution

Eli_Lippard 0600022DVH | | Comment (1) | Visits (3137)

  The following is written from the perspective of using fixed partition placement strategy.  Fixed partition is the recommended placement strategy and is in use by almost all WXS environments.   Shard Distribution: WXS partitions consist of the primary shard and “n” number of replica shards.  The replica shards have the same data as the primary shard and ensure that the data is available in case the primary shard is lost.  With developmentMode set to false, shards from the same partition will not be placed...

Understanding the NFS health check on DataPower

Aidan Harbison 310000JE0Y | | Visits (3915)

Tweet
  This publication assumes the use of a currently supported DataPower firmware version at the time of posting.   Background DataPower offers the ability to configure both Static and Dynamic NFS mounts. For the purpose of this discussion, we will be assuming the use of the NFS Static Mount , as this is the most common and more widely seen in the field. An NFS Static Mount on DataPower mounts a directory from a remote file system to DataPower's to allow access for reading and writing files to the remote server. This not only can be... [More]

  When you are monitoring connection pool performance, you may occasionally notice that connections are staying open for long periods of time. This behavior can have many different causes and can lead to issues like the connection pool maxing out. The J2CA0045E message is a good indication that your connection pool is maxed out: J2CA0045E: Connection not available while invoking method createOrWaitForConnection for resource jdbc/xxxxxx Some of the most common issues that can lead to connections staying open for longer than intended are the...

DataPower and HTTP Persistence

Chris Sloan 27000763MF | | Visits (4288)

Tweet
    What is HTTP Persistence?   Whether knowingly or unknowingly, HTTP persistence is likely something you encounter on a regular basis when using your DataPower to communicate with backends and clients alike. By default HTTP persistence is enabled, though it can be manually disabled. HTTP persistence allows clients and servers to continue to exchange HTTP requests and responses without the overhead of establishing a new TCP connection for each request. Instead a TCP connection will be established and can be re-used multiple... [More]
