DB2 II V8.2 for ORACLE 创建nickname时导致DB2 CRASH的解决方法(Linux) (注:DB2 II 已经改名为Websphere II) 在使用 II4O时，创建Wrapper, user mapping都没问题，但是，当创建nickname时，DB2 crash。 在db2diag.log 中，有如下信息:2005-03-13-14.22.36.412133+480 E7747G606 LEVEL: Severe

Look for trap files (t19883.*) in the dump directory 检查trap文件， t19883.000, 在 call stack，会发现:-FRAME-- --CODE-- --LOCATION--

(/home/oracle/OraHome1/lib/libclntsh.so.9.0) 这是DB2 II V8.2 和 Oracle 9i/10g 的一个兼容性问题. 假如是ORACLE 9i Workaround:1) Back up your $ORACLE_HOME/lib/libclntsh.so and
$ORACLE_HOME/bin/genclntsh
2) 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 command
3) Run genclntsh to create libclntsh.so
4) Execute djxlinkOracle
5) Stop and Start the instance 假如是ORACLE 10g Workaround:1) back up $ORACLE_HOME/bin/genclntsh,
$ORACLE_HOME/lib/libclntsh.so.10.1, $ORACLE_HOME/lib32/libclntsh.so.10.1
2) cd $ORACLE_HOME/lib; mv libnnz10.so libnnz10.so.orig
(so libnnz10.so not exist in lib)
3) cd $ORACLE_HOME/bin; modify the script genclntsh:
a). Add "-Wl, -Bsymbolic" to linker line, .... make sure there is no
spaces between the comma and -B.
ex. LD="gcc -shared -Wl,-relax -L${ORACLE_HOME}/lib -Wl,
-Bsymbolic" # shared library link command
b) Change libnnz10.so ==> libnnz10.a in following line
* -r ${OLIB}/libnnz10.so * && LNZ="-lnnz10
