Monitoring WebLogic JDBC Resources 13-3
■
Timestamp - time stamp showing when the connection was given to the thread
13.2.1.2 Connection Reservation Wait PROFILE_TYPE_CONN_RESV_WAIT_STR
Enable connection reservation wait profiling to collect information about threads currently waiting to reserve a connection from the data source. This profile
information can help determine why applications are unable to get connections from the data source or to wait for connections. The record contains the following
information:
■
PoolName - name of the data source to which this connection belongs
■
ID - thread ID
■
User - stack trace of the thread waiting for the connection
■
Timestamp - time stamp showing when the thread started waiting for a connection
13.2.1.3 Connection Reservation Failed PROFILE_TYPE_CONN_RESV_FAIL_STR
Enable connection reservation failure profiling to collect information about threads that attempt to reserve a connection from the data source but fail to get that
connection. This profile information can help determine why applications are unable to get connections from the data source even after reserving them. The record contains
the following information:
■
PoolName - name of the data source to which this connection belongs
■
ID - thread ID
■
User - stack trace of the thread waiting for the connection plus the exception received when the reservation request failed
■
Timestamp - time stamp showing when the reservation request failed
13.2.1.4 Connection Leak PROFILE_TYPE_CONN_LEAK_STR
Enable connection leak profiling to collect information about threads that have reserved a connection from the data source and the connection leaked was not
properly returned to the pool of connections. This profile information can help determine which applications are not properly closing JDBC connections. The record
contains the following information:
■
PoolName - name of the data source to which this connection belongs
■
ID - connection ID
■
User - stack trace of the thread waiting for the connection
■
Timestamp - time stamp showing when the connection leak was detected
13.2.1.5 Connection Last Usage PROFILE_TYPE_CONN_LAST_USAGE_STR
Enable connection last usage profiling to collect information about the previous thread that last used the connection. This information is useful when you are debugging
problems with connections infected in pending transactions that cause subsequent XA operations on the connections to fail. The record contains the following information:
■
PoolName - name of the data source to which this connection belongs
■
ID - stack trace of the XA exception thrown
■
User - stack trace of the thread that last used the connection

■
Timestamp - timestamp showing when the exception was thrown
13.2.1.6 Connection Multithreaded Usage PROFILE_TYPE_CONN_MT_USAGE_ STR
