DB II V for ORACLE 创建nickname时导致DB CRASH的解决方法(Linux)

　　(注:DB II 已经改名为Websphere II)

　　在使用 II O时创建Wrapper user mapping都没问题但是当创建nickname时 DB crash

　　在db diag log 中有如下信息: + E G LEVEL: SeverePID : TID : PROC : db agent(SAMPLE)INSTANCE: db inst NODE : DB : SAMPLEAPPHDL : APPID: GAC NE F FUNCTION: DB UDB oper system services sqloEDUCodeTrapHandler probe: MESSAGE : ADM C An unexpected internal processing error has occurred ALL DB PROCESSES ASSOCIATED WITH THIS INSTANCE HAVE BEEN SHUTDOWN Diagnostic information has been recorded Contact IBM Support for further assistance + I G LEVEL: SeverePID : TID : PROC : db agent(SAMPLE)INSTANCE: db inst NODE : DB : SAMPLEAPPHDL : APPID: GAC NE F MESSAGE : RDS UCINTFC: pStatementText =DATA # : Hexdump bytes xB E : E B E D CREATE NICKNAME xB F : E E F C F DB INST ORALOCA xB A : C F E E L FOR TSH DB IN xB A : E C F C ST LOCAL + I G LEVEL: SeverePID : TID : PROC : db tcpcmINSTANCE: db inst NODE : FUNCTION: DB UDB oper system services sqloEDUSIGCHLDHandler probe: DATA # : String bytesDetected the death of an EDU with process id The signal number that terminated this process was Look for trap files (t *) in the dump directory

　　检查trap文件 t 在 call stack 会发现: FRAME CODE LOCATION BFFE E C A x + A_SHAFinalCommon (/opt/IBM/db /V /lib/libdb e so )BFFE F B E D x ae + A_X RandomUpdate (/home/oracle/OraHome /lib/libclntsh so )BFFE F C CEB x d + ztcrseed (/home/oracle/OraHome /lib/libclntsh so )

　　这是DB II V 和 Oracle i/ g 的一个兼容性问题

　　如果是ORACLE i Workaround: ============ ) Back up your $ORACLE_HOME/lib/libclntsh so and $ORACLE_HOME/bin/genclntsh ) Add Wl Bsymbolic to the link line of $ORACLE_HOME/bin/genclntsh: LD= gcc shared Wl relax L$ORACLE_HOME/lib Wl Bsymbolic # shared library link mand ) Run genclntsh to create libclntsh so ) Execute djxlinkOracle ) Stop and Start the instance
