请教各位，我遇到了如下问题：
环境： HP-UX AI64+ORACLE RAC 10G+OCCI
问题： 在写CLOB字段时，被锁阻塞住，一直未能释放，这是堆栈信息：

请各位不吝指教，多谢！
这是我的部分代码
=========================================================
Environment::Mode eMode;eMode = (Environment::Mode)(Environment::THREADED_MUTEXED | Environment::OBJECT);_Env = Environment::createEnvironment("SIMPLIFIED CHINESE_CHINA.UTF8","SIMPLIFIED CHINESE_CHINA.AL16UTF16", eMode);
_Env->setCacheOptSize(41943040);
_Env->setCacheMaxSize(10);
.....stmt = pOraCn->createStatement(sCLOBSQL);
if ( NULL != stmt )
{
ResultSet* rs = NULL; rs = stmt->executeQuery();
if ( NULL != rs )
{
if ( oracle::occi::ResultSet::END_OF_FETCH != rs->next() )
{
Clob vClob; vClob = rs->getClob(1);
vClob.open();
try
{
vClob.write(sVal.length(), (unsigned char*)sVal.c_str(), sVal.length(), 1);
}
catch ( ... )
{
//
}
vClob.close();
}
stmt->executeUpdate();
stmt->closeResultSet(rs);
}
pOraCn->commit();
pOraCn->terminateStatement(stmt);
}

希望各位同学多多指点！
