Hi! I try to restore DB2 in single system from SLB(System-Level Backup), but Restore System failed.What I do wrong?Steps:

1.STOP DB2.
2.Run DSNJU004 and search the "DATA COMPLETE LRSN" in section "BACKUP SYSTEM UTILITY HISTORY".DATA COMPLETE LRSN = 001A763957A4
3.Run DSNJU003 with CRESTART CREATE,SYSPITR=001A763957A4
4.Close the catalog:/F CATALOG,UNALLOCATE(DSN.USER.CATALOG)
5.START DB2 access(maint)
6.Run RESTORE SYSTEM
But get the following error:...UNABLE TO CONNECT TO DB2, REASON=X'00F30056'...

In User Guide I read thatB2 was rejected. DB2 had been started in restrictedaccess mode. Only authorization IDs authorized toperform maintenance functions are permitted access toDB2.
Probably I don't have a sufficient rule? I have SYSADM + ACCESSCTRL + DATAACCESS.The Backup was made as: BACKUP SYSTEM FULL
Any help would be appreciated!
