ORA-02095: specified initialization parameter cannot be modified

After identifying that the registered control files are incorrect (after receiving the ORA-00205: error in identifying control file, check alert log for more info error) though after executing the system set control files, I would receive and ORA-02095: specified initialization parameter cannot be modified error
May 30, 2014
OIM-11gR2-PS2
ORA-02095: specified initialization parameter cannot be modified

When trying to initiate the DB instance, I would receive the following error:
June 16, 2014
Oracle-Databases

ERROR at line 1: ORA-02095: specified initialization parameter cannot be modified

I would run the 'SQL show parameter control_files

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_files string /home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/ora_control1, /home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/ora_control2

You can see that the control_files are not pointing to the correct location
Actual locations
/home/oracle/app/oracle/oradata/orcl/control01.ctl
/home/oracle/app/oracle/flash_recovery_area/orcl/control02.ctl

ls -la /home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/ora_control1
/home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/ora_control2

So I tried altering the control files...

ALTER SYSTEM SET control_files='/home/oracle/app/oracle/oradata/orcl/control01.ctl','/home/oracle/app/oracle/flash_recovery_area/orcl/control02.ctl'
ALTER SYSTEM SET control_files='/home/oracle/app/oracle/oradata/orcl/control01.ctl'

-- Now i'm getting the following error

SQL ALTER SYSTEM SET control_files='/home/oracle/app/oracle/oradata/orcl/control01.ctl','/home/oracle/app/oracle/flash_recovery_area/orcl/control02.ctl'
2 ;
ALTER SYSTEM SET control_files='/home/oracle/app/oracle/oradata/orcl/control01.ctl','/home/oracle/app/oracle/flash_recovery_area/orcl/control02.ctl'
*
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified

So I tried this...

ALTER SYSTEM SET control_files='/home/oracle/app/oracle/oradata/orcl/control01.ctl','/home/oracle/app/oracle/flash_recovery_area/orcl/control02.ctl' scope=spfile;

Then this...

ALTER SYSTEM SET control_files='/home/oracle/app/oracle/oradata/orcl/control01.ctl' scope=spfile;

Still getting..

ERROR at line 1: ORA-02095: specified initialization parameter cannot be modified


SOLUTION

I was able to create a new SPFILE from the PFILE, which allowed me to initiate the startup

CREATE SPFILE FROM PFILE='/home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/initorcl11gR2.ora';

Then I was able to connect...

[oracle@localhost dbs]$ sqlplus sys/Password1@localhost.localdomain:1521/ORCL as sysdba

HOW TO provision AD group membership from OpenIDM

OpenIDMICFAD-connector

June 15, 2018
Created by: Daniel Redfern
For what I see, there's not too many supportive documentations out there that will demonstrate how provision AD group membership with the ICF connector using OpenIDM. The use of the special ldapGroups attribute is not explained anywhere in the Integrators guides to to the date of this blog. This quick blog identifies the tasks required to provision AD group membership from OpenIDM to AD using the LDAP ICF connector. However this doesn't really explain what ldapGroups actually does and there's no real worked example of how to go from an Assignment to ldapGroups to an assigned group in AD. I wrote up a wiki article for my own reference: AD group memberships automatically to users This is just my view, others may disagree, but I think the implementation experience could be improved with some more documentation and a more detailed example here.
