weblogic.ejb.extensions.LockTimeOutException HELP!

[Roberto]

Hi,

We're seeing weblogic.ejb.extensions.LockTimeOutException when we try
to access some Entity Bean's data member. I'm wondering someone could
help us?

There is some background:
WL server 5.1, SP10 (almost sure:)
Running in Solaris w/ Oracle 8i

The sequence of calls is:
IWorkspaceRemote workspace = (IWorkspaceRemote)
getEntityBean(EJBConstants.JNDI_NAME_WORKSPACE, new
Long(workspaceID));
WorkspaceDetailData wsData = workspace.getWorkspaceDetailData();
( the EJB home is cached in memory ***)

Inside ejbLoad() we're using the Composite Entity EJB pattern (for
lazy loading) and looks something like this:
void ejbLoad() {
m_baseData = loadBaseData();

if (m_detailData != null) {
m_detailData = loadDetailData();
}
}

DetailData getWorkspaceDetailData() {
if (m_detailData == null) {
m_detailData = loadDetailData();
}
}

THe stack trace I get is:
weblogic.ejb.extensions.LockTimedOutException: Lock for
primaryKey:21071 timed out after 60000 ms.

Any ideas?

Hi Roberto,

Check CP, data sources (if they are available in 5.1) etc for oracle instance
parameters like servers, user ids, passwords, urls etc.
