J2C Connection Pools workspace

This workspace reports information about resource adapters and connectors that adhere to J2C, the WAS implementation of the JCA.

Data counters for this category contain usage information about the J2C connection pools that enable enterprise beans to connect to and interact with systems such as the Customer Information Control System (CICS) and the Information Management System (IMS™). This workspace displays data provided by the J2C Connection Pools attributes.

• This workspace reports blanks for resource data on the first invocation if PMI data collection is configured for on-demand sampling (that is, if your site set configuration value Resource Data Collection Method to On Demand) or if you have not yet run applications that generate PMI resource data. To report resource data in this workspace after installing and configuring the data collector, use the WebSphere administrative console to set the appropriate PMI instrumentation level.

• Because of high overhead, the Tivoli Enterprise Monitoring Agent provides on demand sampling by default. To activate PMI monitoring, first select this workspace and then select it again later. Each time you select the workspace, it displays the data collected during the interval between selections.

The predefined workspace contains the following items:

• Highest Average Pool Sizes bar chart, which shows the largest average number of managed connections for each J2C connection pool. The Y-axis headings correspond to the row number of the J2C Connection Pools report

• Worst Wait Times bar chart, which shows the worst wait time (in milliseconds) for each of the J2C connection pools. The y-axis headings correspond to the row number of the J2C Connection Pools report

• Highest Allocation Rates bar chart

  Displays the highest managed-connection creation, destruction, and allocation rates (in events per second)

• J2C Connection Pools report, which displays information about connectors that adhere to J2C. For example, this report displays the number of managed connections or physical connections and the total number of connections or connection handles
