Error description

  • Sometimes after startup (happens within a few minutes after
    startup)all db connections are allocated and not returned to
    the pool.No error messages mirrors the problem.
    The traces show that the jca processing runs a shared and a
    non-shared connection manager. On the next getConnection()
    however only one of them is used, here
    JNDI Name <jdbc/acp01>
    shareable <false>
    while jdbc/acp01_ref_jta and jdbc/acp01_ref_nonjtaare
    expected.
