Creating a link for short-on-storage

The purpose of this procedure is to create a link from the Storage Analysis workspace to the Transaction Analysis workspace.

About this task

The assumption is that a possible reason for going short-on-storage is a rogue transaction. Having a link between two workspaces helps you focus on the potential problem more quickly in the future.

At this point, you notice that one of your EDSAs has gone short-on-storage. This is indicated by the red (critical) icon against the CICS region and the Storage Analysis workspace in the Navigator view.

Opening the Storage Analysis workspace shows the EDSA highlighted in red. The circular gauge in the lower left of the workspace is recording 100%.

However, before you start to create a new link, hover over Storage Analysis in the navigation view. A pop up window appears with some advice. Click the link within the advice, and a window appears showing the condition, some expert advice, and the situation that it relates to.

To create the link to the Transaction Analysis workspace, use this procedure:

Procedure

  1. Right-click Storage Analysis in the Navigator, and click Link to > Link Wizard from the pop up menu.
    The Workspace Link Wizard opens.
  2. Ensure radio button Create a New Link is active, and click Next.
  3. Within the Link Name window, name it Transaction Analysis, and describe it as locate the cause of a short-on-storage condition; then click Next.
  4. Within the Link Type window, set the link type to Absolute, and click Next.
  5. Within the Target Workspace window, define the target workspace: expand the Navigator view until you locate the CICS region with the Short-on-Storage condition, expand that entry, and select Transaction Analysis in both the Navigator view and Workspace view. Click Next.
  6. Ignore the Parameters window, and click Next.
  7. From the Summary window, examine the parameters of your link. If correct, click Finish.
  8. To test your link, from the Navigation view, right-click Storage Analysis, and click Link To > Transaction Analysis.
    You may be prompted to save your workspace; if so, click Yes.
  9. From the Transaction Analysis workspace, sort your transactions in the Wait Type column; click the column label.
    The Wait Type column is on the extreme right of the table. You can drag and drop the column so that it is alongside the task number. You are looking for a transaction that has a wait type of Storage. It is likely that this transaction is causing your CICS® region to go short-on-storage.

What to do next

The end result is that you are shown a transaction that is hung up waiting for additional storage.

The next step is to remove this transaction using the Take Action command. Continue with Resolving the problem: using the Take Action command.
