DB2建立nickname导致CRASH解决方法

【IT168 服务器学院】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:

PID     : 19824                TID  : 3007177376  PROC : db2tcpcm
INSTANCE: db2inst1             NODE : 000

DATA #1 : String, 158 bytes
Detected the death of an EDU with process id 19883
The signal number that terminated this process was 11
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--
BFFE8E70 83C4286A 0x0083 + A_SHAFinalCommon
                  (/opt/IBM/db2/V8.1/lib/libdb2e.so.1)
BFFE8F00 8B55E48D 0x00ae + A_X931RandomUpdate
                  (/home/oracle/OraHome1/lib/libclntsh.so.9.0)
BFFE8F60 83C40CEB 0x00d0 + ztcrseed3
                  (/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.

如果是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

如果是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
