各位高手：我在安装ECC6.0的时候，在update database configuration 的时候，安装报错，错误日志如下：
ERROR 2010-01-11 22:31:52
MDB-01999 Error occured, first error is: <SQL5099N The value "/db2/R3D/log_dir/NODE0000/" indicated by the database >
ERROR 2010-01-11 22:31:52
MUT-03025 Caught ESAPinstException in Modulecall: ESAPinstException: error text undefined.

查看update_db_cfg.log如下：
UPDATE DB CFG FOR R3D USING SOFTMAX 200
DB20000I The UPDATE DATABASE CONFIGURATION command completed successfully.
SQL1363W One or more of the parameters submitted for immediate modification
were not changed dynamically. For these configuration parameters, all

UPDATE DB CFG FOR R3D USING NEWLOGPATH /db2/R3D/log_dir
SQL5099N The value "/db2/R3D/log_dir/NODE0000/" indicated by the database
configuration parameter "NEWLOGPATH" is not valid, reason code "9".

这个log里面没有什么错误信息，只有上面这个NEWLOGPATH无效的信息。我该如何去解决呢，谢谢大家。
