oracle报错（ORA-00600）问题处理
最近在做一个项目，使用的是Oracle数据库，近两天不知道怎么回事，告警日志里总是显示这个错误（ORA-00600:internalerrorcode,arguments:[kcblasm_1],[103],[],[],[],[],[],[]）度娘了一下，终于找到解决
告警日志里这两天一直显示这个错误：
ORA-00600:internalerrorcode,arguments:[kcblasm_1],[103],[],[],[],[],[],[] TueAug1209:20:17CST2014 Errorsinfile/u01/app/oracle/admin/orcl/udump/orcl_ora_29974.trc: ORA-00600:internalerrorcode,arguments:[kcblasm_1],[103],[],[],[],[],[],[] TueAug1209:30:17CST2014 Errorsinfile/u01/app/oracle/admin/orcl/udump/orcl_ora_30084.trc: ORA-00600:internalerrorcode,arguments:[kcblasm_1],[103],[],[],[],[],[],[] TueAug1209:40:17CST2014 Errorsinfile/u01/app/oracle/admin/orcl/udump/orcl_ora_29919.trc: ORA-00600:internalerrorcode,arguments:[kcblasm_1],[103],[],[],[],[],[],[]
网上查的解决办法：
1:临时的解决方法
如果执行计划中是hashjoin造成的，在会话层中设置"_hash_join_enable"=false，如：altersessionset"_hash_join_enabled"=false亦可;
如果执行计划是hashgroupby造成的，设置"_gby_hash_aggregation_enabled"=false
2:根本的解决方法
2.1.优化sql语句，避免遇到bug；
2.2.升级
(1)将数据库升级psu到10.2.0.5.4和11.2可以修正该问题
(2)对于10.2.0.5.0到10.2.0.5.3的版本，打PATCH7612454来避免改错误(该补丁替换lib中的kcbl.o文件)。
通过临时解决办法解决问题示例：
追踪报警日志里提示的trace文件，找到导致出现此错误的sql语句
ORA-00600:internalerrorcode,arguments:[kcblasm_1],[103],[],[],[],[],[],[] CurrentSQLstatementforthissession:
格式化后的sql语句如下：
SELECTINDENTDATE, INDENTGROUP, TRANSDATE, TRANSBY, TRANSGROUP, FEEDBACKBY, FEEDBACKGROUP, FINANCEDATE, FINANCEBY, FINANCEGROUP, TOTALCOST, A.TOTALPAY, PAY_CASH, PAY_POINTS, PAY_ADVANCE1, PAY_ADVANCE2, PAY_TYPE, TRANS_PAY, DISCOUNT_STAFF, DISCOUNT_SPECIAL, GAIN_CASH, GAIN_POINTS, GAIN_ADVANCE1, GAIN_ADVANCE2, TRANS_CUSTNAME, TRANS_TEL, TRANS_PROVINCE, TRANS_CITY, TRANS_ADDRESS, TRANS_ZIPCODE, TRANS_WEIGHT, TRANS_COMMENTS, INDENT_COMMENTS, INDENT_ID, A.PARTNER_GUID, A.PROXY_GUID, TRANS_TEL2, CUST_MEDIA_ID, CUST_PARTNER_GUID, CUST_PROXY_GUID, PARTNER_VALUE, PROXY_VALUE, CUST_PARTNER_VALUE, CUST_PROXY_VALUE, DEALBY, A.FAILREASON, ISFOOT, S_REASONID, DEALFAILREASON, A.PRE_FUND, MEDIA_CALLTYPE, PRE_ADVANCE, WEB_FLAG, NEED_INVOICE, INVOICE_TITLE, TRANS_AREA, ORDERTYPE, PAY_POINTSPRICE, A.MEDIA, USERDEFINEDSTATUS, CUSTOMERNAME, CUSTOMERID FROMELITE.TABCINDENTA LEFTJOINELITE.OBJECTIVEB ONA.RELATION_ID=B.OBJECTIVE_GUID LEFTJOINELITE.CUSTOMERC ONA.CUSTOMER_GUID=C.CUSTOMER_GUID WHERE(INDENTDATEBETWEEN:1AND:2ORB.MODIFIEDDATEBETWEEN:3AND:4);
将变量:1,:2,:3,:4替换成具体的值执行：
SELECTINDENTDATE, INDENTGROUP, TRANSDATE, TRANSBY, TRANSGROUP, FEEDBACKBY, FEEDBACKGROUP, FINANCEDATE, FINANCEBY, FINANCEGROUP, TOTALCOST, A.TOTALPAY, PAY_CASH, PAY_POINTS, PAY_ADVANCE1, PAY_ADVANCE2, PAY_TYPE, TRANS_PAY, DISCOUNT_STAFF, DISCOUNT_SPECIAL, GAIN_CASH, GAIN_POINTS, GAIN_ADVANCE1, GAIN_ADVANCE2, TRANS_CUSTNAME, TRANS_TEL, TRANS_PROVINCE, TRANS_CITY, TRANS_ADDRESS, TRANS_ZIPCODE, TRANS_WEIGHT, TRANS_COMMENTS, INDENT_COMMENTS, INDENT_ID, A.PARTNER_GUID, A.PROXY_GUID, TRANS_TEL2, CUST_MEDIA_ID, CUST_PARTNER_GUID, CUST_PROXY_GUID, PARTNER_VALUE, PROXY_VALUE, CUST_PARTNER_VALUE, CUST_PROXY_VALUE, DEALBY, A.FAILREASON, ISFOOT, S_REASONID, DEALFAILREASON, A.PRE_FUND, MEDIA_CALLTYPE, PRE_ADVANCE, WEB_FLAG, NEED_INVOICE, INVOICE_TITLE, TRANS_AREA, ORDERTYPE, PAY_POINTSPRICE, A.MEDIA, USERDEFINEDSTATUS, CUSTOMERNAME, CUSTOMERID FROMELITE.TABCINDENTA LEFTJOINELITE.OBJECTIVEB ONA.RELATION_ID=B.OBJECTIVE_GUID LEFTJOINELITE.CUSTOMERC ONA.CUSTOMER_GUID=C.CUSTOMER_GUID WHERE(INDENTDATEBETWEEN'2012-06-19'AND'2012-08-19'ORB.MODIFIEDDATEBETWEEN'2012-06-19'AND'2012-08-1');
执行报错：
解决办法：
altersessionset"_hash_join_enabled"=false;
altersessionset"_gby_hash_aggregation_enabled"=false
--先尝试一种，如果一种解决了，就没必要设置另外一种了。
然后再次执行上面的查询语句，不报错啦，嘎嘎
成功啦，(*^__^*)嘻嘻……
让开发人员在程序里加上这条命令即可。
