why i receive error when recover database xxx using history file xxx??

Do you need to specify the history file? Try putting single quotes around it.

i try again the same error

db2 => recover database mydb to end of logs using history file ('/share/db2rhist.asc') overflow log path (/share/archtemp)
SQL4904N The pointer to parameter "piHistoryFile" of function "db2Recover" is

recover db command:

USING HISTORY FILE history-file path


So, try:
....history file (/share/)....

thank you db2girl

you are right

now that's OK

db2 => recover database mydb to end of logs using history file (/share/) overflow log path (/share/archtemp)
