Hi Experts,

We are using "DB2 v9.5.0.4" on AIX platform.

Due to notaion problem our client deleted the db2adm group from server and created a new one. And assigned this new group to the instance owner.

Now while starting the instance we are getting following error:
SQL1092N "DB2INST1" does not have the authority to perform the requested command.

We have change the below parameters

$ db2 get dbm cfg |grep group
SYSADM group name (SYSADM_GROUP) = db2grp1
SYSCTRL group name (SYSCTRL_GROUP) = db2grp1
SYSMAINT group name (SYSMAINT_GROUP) = db2grp1
SYSMON group name (SYSMON_GROUP) = db2grp1
but still it doesnt work. I then tried to update the instance. While updating it gave below error

# ./db2iupdt db2inst1
DBI1135E The primary group 'db2grp1' of user ID 'db2inst1' is
invalid.

Please suggest, how to make this new group as a db2 instacne admin group? Please reply ASAP.
