运行Retrieve time from OTL 请求时,出现错误RCV_OTL_GNRET_PROCESS_RUNNING

查看了当前用户所有的REQUEST,没有running 的Request; 但另一个同事说他有在运行这个Request,尝试了下面的所有方法,但是都没有解决问题。
1.Cancel掉其他用户的Retrieve time from OTL
2.换用其他的Contingent worker创建新的OTL Timecard
3.给当前的Contingent worker创建新的采购订单。
查看当前的Request是对应的Executable 是RCVOTLR, 类型是PL/SQL Stored Procedure,对应的PL./SQL Package和Procedure 是RCV_HXT_GRP.RETRIEVE_TIMECARDS。
通过FND_NEW_MESSAGES得到的错误代码是RCV_OTL_GNRET_PROCESS_RUNNING
SELECT *
FROM fnd_new_messages
WHERE message_text LIKE 'Your request could not complete because an earlier request is still being processed%'
查看相应的procedure RCV_HXT_GRP.RETRIEVE_TIMECARDS,根据错误代码RCV_OTL_GNRET_PROCESS_RUNNING搜索,可以发现是在调用procedure HXC_INTEGRATION_LAYER_V1_GRP.Execute_Retrieval_Process时,发生异常并且异常代码类似 ‘ORA-20001: HXC_0017_GNRET_PROCESS_RUNNING’ 时抛出的。
BEGINg_generic_start := SYSDATE;HXC_INTEGRATION_LAYER_V1_GRP.Execute_Retrieval_Process(P_Process => 'Purchasing Retrieval Process',P_Transaction_code => NULL,P_Start_Date => l_start_date,P_End_Date => l_end_date,P_Incremental => 'Y',P_Rerun_Flag => 'N',P_Where_Clause => l_where_clause,P_Scope => 'DAY',P_Clusive => 'EX');g_generic_stop := SYSDATE;g_generic_time := g_generic_time + (g_generic_stop - g_generic_start);EXCEPTIONWHEN OTHERS THENRCV_HXT_GRP.string( log_level => FND_LOG.LEVEL_EXCEPTION, module => l_log_head, message => 'Generic Retrieval failed: ' || SQLERRM);IF SQLERRM like 'ORA-20001: HXC_0013_GNRET_NO_BLD_BLKS%' ORSQLERRM like 'ORA-20001: HXC_0012_GNRET_NO_TIMECARDS%' THENG_CONC_LOG := G_CONC_LOG || FND_MESSAGE.get_string('PO', 'RCV_OTL_GNRET_NO_TIMECARDS')|| FND_GLOBAL.local_chr(10) || FND_GLOBAL.local_chr(10);RAISE SUCCESS_SHORT_CIRCUIT;ELSIF SQLERRM like 'ORA-20001: HXC_0017_GNRET_PROCESS_RUNNING%' THENG_CONC_LOG := G_CONC_LOG || FND_MESSAGE.get_string('PO', 'RCV_OTL_GNRET_PROCESS_RUNNING')|| FND_GLOBAL.local_chr(10) || FND_GLOBAL.local_chr(10);END IF;RAISE GENERIC_RETRIEVAL_FAILED;END;
HXC_INTEGRATION_LAYER_V1_GRP.Execute_Retrieval_Process 后面会调用HXC_GENERIC_RETRIEVAL_PKG.execute_retrieval_process来做实际的retrieve.
在HXC_GENERIC_RETRIEVAL_PKG.execute_retrieval_process搜索‘ORA-20001: HXC_0017_GNRET_PROCESS_RUNNING’,发现 exception为e_process_already_running,才会抛这个错误。
EXCEPTIONWHEN e_retrieval_not_registeredTHENfnd_message.set_name ('HXC', 'HXC_0011_GNRET_NOT_REGISTERED');fnd_message.raise_error;WHEN e_process_already_runningTHENfnd_message.set_name ('HXC', 'HXC_0017_GNRET_PROCESS_RUNNING');fnd_message.raise_error;WHEN e_no_rangesTHENfnd_message.set_name ('HXC', 'HXC_0012_GNRET_NO_TIMECARDS');fnd_message.raise_error;WHEN OTHERS
往上看,可以看到当检查是否有运行的Retrieve 的Concurrennt request时候,返回false的时候就会抛出异常e_process_already_running
IF NOT check_concurrency_ok(p_process_id => g_retrieval_process_id,p_retrieval_process => g_params.p_process,p_where_clause => g_params.p_where_clause,p_unique_params => g_params.p_unique_params)THENRAISE e_process_already_running;END IF;
这里g_params.p_process 是 RCV_HXT_GRP.RETRIEVE_TIMECARDS 传进来的 'Purchasing Retrieval Process',可以通过下面的SQL获取
p_process_id,这里获得的41
SELECT rtr.retrieval_process_id, rtr.time_recipient_id,rtr.mapping_idFROM hxc_retrieval_processes rtrWHERE rtr.NAME = 'Purchasing Retrieval Process'
对于'Purchasing Retrieval Process', function check_concurrency_ok 会通过Cursor 检查在hxc_transactions里有没有正在处理的'Purchasing Retrieval Process', 如果有,就会返回false,execute_retrieval_process就会抛出异常e_process_already_running. 否则,就会进行正常的Retrieve过程。
CURSOR chk_transactionISSELECT transaction_idFROM hxc_transactions txWHERE transaction_process_id = p_process_idAND status = 'IN PROGRESS';
简单粗暴的方法就是直接删掉 hxc_transactions里面的这条记录,或者是把它的status update 成其他的东西, 但极有可能会造成timecard 的data corruption,最保险的方法是给Oracle提一个SR。 但由于我是个人的开发测试环境,毫不犹豫的删掉了它,重新提交Retrieve time from OTL,万事OK!
