Closing User Connections and Releasing Locks

Closing User Connections and Releasing Locks

Sometimes, the PowerCenter Repository Service does not immediately disconnect a user from the repository. The repository has a residual connection when the repository client or machine is shut down but the connection remains in the repository. This can happen in the following situations:
  • Network problems occur.
  • A PowerCenter Client, PowerCenter Integration Service, PowerCenter Repository Service, or database machine shuts down improperly.
A residual repository connection also retains all repository locks associated with the connection. If an object or folder is locked when one of these events occurs, the repository does not release the lock. This lock is called a residual lock.
If a system or network problem causes a repository client to lose connectivity to the repository, the PowerCenter Repository Service detects and closes the residual connection. When the PowerCenter Repository Service closes the connection, it also releases all repository locks associated with the connection.
A PowerCenter Integration Service may have multiple connections open to the repository. If you close one PowerCenter Integration Service connection to the repository, you close all connections for that service.
Closing an active connection can cause repository inconsistencies. Close residual connections only.
To close a connection and release locks:
  1. In the Administrator tool, click the
    Manage
    tab >
    Services and Nodes
    view.
  2. In the Domain Navigator, select the PowerCenter Repository Service with the connection you want to close.
  3. In the contents panel, click the
    Connections & Locks
    view.
  4. In the contents panel, select a connection.
    The details panel displays connection properties in the properties view and locks in the locks view.
  5. In the
    Manage
    tab
    Actions
    menu, select
    Delete User Connection
    .
    The
    Delete Selected Connection
    dialog box appears.
  6. Enter a user name, password, and security domain.
    You can enter the login information associated with a particular connection, or you can enter the login information for the user who manages the PowerCenter Repository Service.
    The
    Security Domain
    field appears when the Informatica domain contains an LAP security domain.
  7. Click
    OK
    .
The PowerCenter Repository Service closes connections and releases all locks associated with the connections.
