在windows xp下,DB不能启动实例。运行db2start,报以下错误:
DB2 : The service has returned a service-specific error code.
SQL1220N The database manager shared memory set cannot be allocated.
在IBM官网会有记录这个错误,解决方法很简单,
Set INSTANCE_MEMORY to AUTOMATIC by issuing the following from a DB2 Command Window:
db2 update dbm cfg using INSTANCE_MEMORY AUTOMATIC
Re-attempt to start your instance.
