I missed to add Standby Logfile groups? What now?

Hi there
I have created a Standby database in a test environment using RMAN   (followed the procedure given here -> URL: Creating a Standby Database with Recovery Manager).
When I tried to start the recovery on Standby, I got the following error:
[code]
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT
ERROR at line 1:
ORA-38500: USING CURRENT LOGFILE option not available without stand
SQL> select NAME, OPEN_MODE, GUARD_STATUS, DATABASE_ROLE from v$database;
NAME      OPEN_MODE GUARD_S DATABASE_ROLE
PRIM      MOUNTED    NONE    PHYSICAL STANDBY
SQL>
[/code]
I missed the step to add standby logfile groups. Do I need to recreate the Standby database now? I mean, add standby logfile groups to Primary, then take full RMAN backup and recreate the standby database (following the procedure described in the URL above)?
I am using Oracle 10gR2 on OEL 5.8.
Please advise!
Best regards

OK thank you both - I have added the standby logfile groups both on Primary and Standby (mounted) database and I was able to successfully issue the following command:
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
I hope this was the right thing to do under the circumstances, right?
And now there seems to be a gap:
PRIM_SQL> SELECT MAX(SEQUENCE#) FROM V$ARCHIVED_LOG;
MAX(SEQUENCE#)
            11
STDBY_SQL> SELECT MAX(SEQUENCE#) FROM V$LOG_HISTORY;
MAX(SEQUENCE#)
             9
I issued "alter system switch logfile" few times on the Primary but logs don't seem to be shipping? How to check this and fix?
EDIT: OK I checked the Primary alert log file and see following messages:
Error 1031 received logging on to the standby
Tue Jun 25 15:22:43 2013

Tue Jun 25 15:32:43 2013
I do have password file both on Primary and Standby servers. What is this "ORA-01031: insufficient privileges" referring to?
EDIT#2:
I copied the password file from Primary DB server to Standby server (with same name "orapwprim" - previously I used "orapwstan" name for standby password file) and the "login issue" is resolved. But now I see following error in the alert log file on Primary:
PING[ARC0]: Heartbeat failed to connect to standby 'stan'. Error is 1031.
Tue Jun 25 15:48:08 2013
ARCH: Possible network disconnect with primary database
Any clues here?
EDIT#3:
Sorry I was a bit impatient I guess.The logs a re being shipped and applied now.
Thank you both!
Best regards

Alter database clear unarchived logfile group... who, what?

I am the sole DBA for our site, all of them running RHEL 5, Oracle 11.2.0.3.
I recently (within the last hour), received a text message from one of our databases that poll the alert.log...
ORA-1031 signalled during: ALTER DATABASE CLEAR UNARCHIVED LOGFILE GROUP 3
Unfortunately, the 'audit database' was not enabled (it is now!), and the trace file generated did not contain anything of use.
I know someone has been loading data since 1:30pm up until near the time I received this text, and I'm wondering if he is mucking in the system, or if this command can somehow be generated automatically by Oracle. If so, I certainly wouldn't expect an ORA-1031insufficient permissions error....
I checked my v$log, v$logfile, and did a log switch just to check if any possibility of redo log corruption, but all looks fine.
Has anyone else ever had random Oracle errors like this?....

Hi,
That's someone manually doing something when they really don't know what they are doing. I've only had to run that command once in 16 years as a dba. Oracle wouldn't ever run that itself.
Cheers,
Harry

What is the Use of "Alter database activate standby database"

Hi ,
I appreciate your time.
I just wanted to know what is the use of "Alter database activate standby database" command when doing the failover. How different it will act in failover process. Can we use this command in SwitchOver.
Thanks in advance.

Hi Uwe Hesse,
Wonderfull... good info....
So my understanding is that the use of "ACTIVATE PHYSICAL STANDBY DATABASE" is conditional and depends on the redo log gap and the Database status(Able to mount or not).
Condition 1: If the Db is in Mount state and Redo log gap is successfully filled.
1) Flush any unsent redo from the primary database to the target standby database.
SQL> ALTER SYSTEM FLUSH REDO TO target_db_name;
Note: If the above Statement Completes successfully without any errors.
2) Stop Redo Apply.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
3) Finish applying all received redo data.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE FINISH;
4) Verify that the target standby database is ready to become a primary database.
SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE;
5) Switch the physical standby database to the primary role.
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY WITH SESSION SHUTDOWN;
Condition 2: If the DB is not able Mount and Redo Gap can't be filled.
Important Note: If the the above command in STEP3 gives error, some received redo data was not applied. Try to resolve the cause of the error and re-issue the statement before proceeding.
If the error condition cannot be resolved, a failover can still be performed (with some data loss) by issuing the following SQL statement on the target standby database:
SQL> ALTER DATABASE ACTIVATE PHYSICAL STANDBY DATABASE;
Thanks in advance.

I tried to track any info in the web and metalink, but it's the first time I encounter an ORA error with no documentation... :(
Some facts:
The oracle is 11.2.0 on Linux
There is no space issue on disk
Thanks for any help/ideas...

thanks for the reply.
first one I stated in the original post. there is tons of storage :)
for the others 2 -
user has priviledge... he created the first file succesfully...
those files do not exist on the disk already.
Thanks

Can't switch standby logfiles to status=active

Hi DBA's
I'm trying to create logical standby on 10.2 on fedora 6 on manual http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#g88234
I can't create proper working standby redo logs.
ALTER DATABASE ADD STANDBY LOGFILE GROUP 4
('/u01/app/oracle/oradata/ORCL/onlinelog/log4a.log',
'/u01/app/oracle/flash_recovery_area/ORCL/onlinelog/log4b.log') SIZE 50M;
then create the rest of standby redos and switch logfile:
ALTER SYSTEM SWITCH LOGFILE;
when:
SQL> SELECT GROUP#,THREAD#,SEQUENCE#,ARCHIVED,STATUS FROM V$STANDBY_LOG;
GROUP# THREAD# SEQUENCE# ARC STATUS
4 0 0 YES UNASSIGNED
5 0 0 YES UNASSIGNED
6 0 0 YES UNASSIGNED
What to do?
Edited by: val75 on Jun 21, 2009 11:08 PM

try switch log at primay
please try to run this Command and then open the primary database.
alter database set standby database to maximize performance;
alter database open;

Standby logfiles

In the following doc: http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/log_transport.htm#BABCBEGJ
it says:
For example, assume that the redo log on the redo source database has two redo log groups and that each of those contain one 500 MB redo log file. In this case, the standby redo log should have at least 3 standby redo log groups to satisfy the requirement that a standby redo log must have at least one more redo log group than the redo log at the redo source database.
The following SQL statements might be used to create a standby redo log that is appropriate for the previous scenario:
ALTER DATABASE ADD STANDBY LOGFILE
('/oracle/dbs/slog1.rdo') SIZE 500M;
ALTER DATABASE ADD STANDBY LOGFILE
('/oracle/dbs/slog2.rdo') SIZE 500M;
ALTER DATABASE ADD STANDBY LOGFILE
('/oracle/dbs/slog3.rdo') SIZE 500M;
The doc says there needs to be one more group and then demonstrates creating no seperate groups. Did they mean to say one more file or did they mean to create groups such as this:
ALTER DATABASE ADD STANDBY LOGFILE GROUP 1...
ALTER DATABASE ADD STANDBY LOGFILE GROUP 2...
ALTER DATABASE ADD STANDBY LOGFILE GROUP 3....

In the example the primary database has two log groups, and then they create 3 standby log groups on the standby. This is exactly what they recommend (standby = primary + 1).

Standby logfile missing error

Hello all,
I am getting this following error in standby alertlog file.
ORA-00313: open failed for members of log group 8 of thread 2

ORA-15012: ASM file '+DG_DATA/hsipstl/onlinelog/group_8.1766.779638759' does not exist
When i manually check the diskgroup '+DG_FLASH, +DG_DATA, i can see the group_8 file with some other numbers.
Kindly let me know how to proceed for that. oracle 11g database, standalone standby database in aix box
My guess is control file is still thinking that the group 8 file is present and looks for it when starting the standby, but actually that file is not there in the diskgroup. instead some other filename is there for the same group.
Either i want to update the control file about the new log group 8, or drop the log 8 group, delete the log 8 group files from the disgroups +DG_FLASH, +DG_DATA and create a new log 8 group
Kindly suggest
Regards,

Oracle ORA_16000 when trying to add standby instance to existing rac node

I attempted to use dbca to add a new standby instance to an existing cluster. The cluster is 4 nodes, Linux RHEL 5.3 Oracle 11.1.0.7. Also using ASM, asmlib, ocfs2 and shared block devices.
ASM instances are up and functional on all nodes. current config appears to be running normally and correctly.
I have a 4 instance database running on the cluster. I also have 3 physical standby active data guard instances running on 3 of the nodes. I wanted to add a new ADG instance to the 4th node.
While running dbca I received ORA-00604 and ORA-16000.
The active data guard database was open (read only) and redo apply was on. I am using data guard broker as well, but not grid control.
Does anyone have a procedure for adding an instance in this environment? Do I need to have the standby in mount state? If dbca won't work does anyone have a manual procedure for adding a new instance?
Thanks

4. After this is done crs_stat -t will show nusclust160## in the crs i.e.
I see:
Name Type Target State Host
ora....160##.gsd application ONLINE ONLINE sun...160##
ora....160##.ons application ONLINE OFFLINE
ora....160##.vip application ONLINE ONLINE sun...160##
Do not be concerned about ora.nusclust160##.ons being OFFLINE, as that will be fixed shortly in a step that follows this one.
5. As oracle :
On nusclust16007:
cd /apps/ocr/oracle/product/11.1.0/crs/bin
./racgons add_config nusclust160##:6251
This should take about one second to run.
If it says that it has already been added to the OCR you are fine.
If it hangs, you may need to reboot all servers to clear this issue.
6. Insure new node is properly added to ocr by running
On nusclust16007:
ocrdump
Check for the entries that show:
[DATABASE.ONS_HOSTS.nusclust160##.PORT]
ORATEXT : 6251
7. Check that your cluster is integrated and that the cluster is not divided into
partitions by completing the following operations:
On nusclust16007:
cd /apps/ocr/oracle/product/11.1.0/crs/bin
./cluvfy comp clumgr -n all -verbose
Should see Verification of cluster manager integrity was successful.
8.
Use the following command to perform an integrated validation of the Oracle
Clusterware setup on all of the configured nodes, both the preexisting nodes
and the nodes that you have added:
AS oracle on nusclust16007:
cluvfy stage -post crsinst -n all -verbose
Post-check for cluster services setup was successful.
good: Post-check for cluster services setup was successful.
9.
On nusclust160## as oracle run the following:
cd /apps/ocr/oracle/product/11.1.0/crs/bin
./crs_stat -t | grep OFFLINE
If you see this:
ora.nusclust160##.ons application ONLINE OFFLINE
then run this:
./crs_start -all
After:
./crs_stat -t
ora.nusclust160##.ons application ONLINE ONLINE nusclust160##
If you see the above then you can move on the next step.
Adding database binaries to the nusclust160## server and setting up the listener.
1.
From nusclust16007:
Open an X window (The OUI part takes 13 minutes)
cd /apps/dbs/oracle/product/11.1.0/db_1/oui/bin
./runInstaller -addNode ORACLE_HOME=/apps/dbs/oracle/product/11.1.0/db_1 $*
You should get a prompt to specify a new node, in this case you should see nusclust160## where you will need to put a check mark beside it.
2.
from nusclust160##:
Eventually you will be prompted to run the following as root on the new node
On nusclust160##
cd /apps/dbs/oracle/product/11.1.0/db_1
./root.sh
Running Oracle 11g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle

Enter the full pathname of the local bin directory: [usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...

Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
Finished product-specific root actions.
3. verification
Now set up the .bash_profile and .asm profile to on nusclust160## to support new ORADB4 and +ASM4 instances for the oracle userid.
On nusclust160##:
cp .bash_profile .bash_profile.bak
On nusclust16007:
sftp nusclust160##
put .bash_profile
On nusclust160##:
vi .bash_profile
change ORALCE_SID to ORADB4
cp .bash_profile .asm
vi .asm
change ORALCE_SID to +ASM4 in .asm file
which sqlplus
Should show the path below is $PATH environmental variable is set correctly.
/apps/dbs/oracle/product/11.1.0/db_1/bin/sqlplus
On nusclust160##:
oifcfg getif
This should show:
ce4 10.333.248.192 global cluster_interconnect
ce5 222.65.125.128 global public
4.
Run Netbackup Oracle Agent link script.
As oracle make sure ORACLE_HOME is fined.
env | grep ORACLE_HOME
then
cd /usr/openv/netbackup/bin/
./oracle_link
ls -al $ORACLE_HOME/lib/libobk.so
should show:
/apps/dbs/oracle/product/11.1.0/db_1/lib/libobk.so -> /usr/openv/netbackup/bin/libobk.so64.1
5.
On the target node, run the Net Configuration Assistant (NETCA) to add a
listener. Add a listener to the target node by running NETCA from the target node and
selecting only the target node on the Node Selection page.
I shall do the following on nusclust160## using X Windows
Now before I do this I see:
crs_stat -t
ora.nusclust160##.gsd application ONLINE ONLINE nusclust160##
ora.nusclust160##.ons application ONLINE ONLINE nusclust160##
ora.nusclust160##.vip application ONLINE ONLINE nusclust160##
Connect to nusclust160## and open up X windows session.
netca
Choose Cluster configuration.
select nusclust160## as the node to configure.
Choose Listener configuration, then Add.
When it prompts you for a listener name choose LISTENER as it will append _NUSCLUST160##(server name) to end of the LISTENER name to make a complete listener name.
At this point you will have listener to support the new node in the crs.
now
crs_stat -t
will show:
ora....0#.lsnr application ONLINE ONLINE nusclust160##
ora.nusclust160##.gsd application ONLINE ONLINE nusclust160##
ora.nusclust160##.ons application ONLINE ONLINE nusclust160##
ora.nusclust160##.vip application ONLINE ONLINE nusclust160##
At this point the necessary crs entries for gsd, ons, vip, and the listener on nusclust160## all we need now are the ORADB4 and +ASM4 instances added.
III. 7/11/2009 7:40 AM Sat [120 min] NTTA DBA
Use NON dbca method to create additional instances on the nusclust160## server. This will involve a complete shutdown of all RAC instances.
1.
Undo tablespace creation was taken care of in Step I,1. Check on the progress of the creation of tablespace UNDOTBS4 in the minimized window. Should see tablespace on primary and physical standby databases.
2. First we shall set up the +ASM4 instance on nusclust160## and add it to the cluster.
On nusclust160##
cd $ORACLE_HOME/dbs
vi init+ASM4.ora

sqlplus '/ as sysasm'
startup
create spfile from pfile='/apps/dbs/oracle/product/11.1.0/db_1/dbs/init+ASM4.ora' ;
shutdown immediate ;
startup
show parameters spfile
6. Now that we have a running asm instance add it the cluster.
On nusclust160##
srvctl add asm -n nusclust160## -i +ASM4 -o /apps/dbs/oracle/product/11.1.0/db_1
srvctl enable asm -n nusclust160## -i +ASM4
7. Now that we have an asm instance let's set up a database instance.
On nusclust16007/ORADB1 :
alter system set cluster_database_instances=6 scope=spfile ;
alter system set instance_name=ORADB4 scope=spfile sid='ORADB4' ;
alter system set instance_number=4 scope=spfile sid='ORADB4' ;
alter system set local_listener=LISTENER_ NUSCLUST160## scope=both sid='ORADB4' ;
alter system set thread=4 scope=both sid='ORADB4' ;
alter system set undo_tablespace=UNDOTBS4 scope=both sid='ORADB4' ;
alter database add logfile thread 4 group 28 ('+REDO1', '+REDO2' ) size 100M ;
alter database add logfile thread 4 group 29 ('+REDO1', '+REDO2' ) size 100M ;
alter database add logfile thread 4 group 30 ('+REDO1', '+REDO2' ) size 100M ;
alter database add logfile thread 4 group 31 ('+REDO1', '+REDO2' ) size 100M ;
alter database enable public thread 4;
Need to add 5 groups to support standby
So at the end of the day 900M will be added to REDO1(29,577M free) and 900M will be added to REDO2 (29,577M free).
8. Set up init.ora, listener.ora, and tnsnames.ora for ORADB4 on nusclust160##.
a. init.ora set up
cd $ORACLE_HOME/dbs
vi initORADB4.ora
SPFILE='+DATA1/ORADB/spfileORADB.ora'
b. add entries to tnsnames.ora:
ORADB4 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORADB)
(INSTANCE_NAME = ORADB4)
ORADB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16007-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16008-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16036-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORADB)
LISTENERS_ORADB =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16007-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16008-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16036-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
LISTENER_NUSCLUST160## =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
ORADB_PRIM =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16007-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16008-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust16036-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = nusclust160##-vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORADB)
c. add entries to listener.ora, The entries for most of this file should be set already, just insure modifications that need to be made are made.
SID_LIST_LISTENER_NUSCLUST160## =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /apps/dbs/oracle/product/11.1.0/db_1)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = ORADB)
(ORACLE_HOME = /apps/dbs/oracle/product/11.1.0/db_1)
(SID_NAME = ORADB4)
LISTENER_NUSCLUST160## =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = NUSCLUST160##-vip)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = 222.65.125.###)(PORT = 1521)(IP = FIRST))
9. Reload the listener.
lsnrclt
set current_listener LISTENER_NUSCLUST160##
reload
exit
10. Check audit trail, add instance to cluster, and start db instance.
a.
Check for audit directory and start the instance.
/apps/dbs/oracle/product/11.1.0/db_1/rdbms/audit
If this audit trail directory does not exist then create it.
b.
srvctl add instance -d ORADB -i ORADB4 -n nusclust160##
srvctl modify instance -d ORADB -i ORADB4 -s +ASM4
srvctl enable instance -d ORADB -i ORADB4
Will probably show: PRKP-1017 : Instance ORADB4 already enabled.
c.
sqlplus '/ as sysdba'
startup
**Because the cluster_database_instances parameter requires the complete shutdown of all instances in the cluster, you might have an issue when it attempts to start the instance. If you receive an error then run:
srvctl stop database -d oradb
sqlplus '/ as sysdba'
startup
shutdown
srvctl start database -d oradb
shutdown
srvctl start instance -d ORADB -i ORADB4 -o open
11.
Modify spfile of ASM1, ASM2, +ASM3
On nusclust16007
. ./.asm
sqlplus '/ as sysasm'
alter system set instance_number=4 scope=spfile sid='+ASM4' ;
On nusclust16008

cd $HOME
. ./.rman
cd scripts
./go
shutdown immediate
cd $HOME
. ./.bash_profile
srvctl stop database -d oradb
crs_stop -all
crs_stat -t
b. Startup resources
On nusclust16007:
cd $HOME
. ./.bash_profile
crs_start -all
crs_stat -t
The command above should show everything up and running.
ocrcheck
On nusclust16008:
cd $HOME
. ./.rman
cd scripts
./go
startup
On nusclust16007:
emctl start dbconsole
On nusclust16008:

Standby logfile

Since setting up RMAN control file autobckup on a dataguard set up I get the following message in the alertlog:-
Starting control autobackup
Sat May 07 01:04:27 2005
Control autobackup written to DISK device
handle 'CF_C-00'
Clearing standby activation ID 2115378951 (0x7e161f07)
The primary database controlfile was created using the
'MAXLOGFILES 9' clause.
There is space for up to 6 standby redo logfiles
Use the following SQL commands on the standby database to create
standby redo logfiles that match the primary database:
ALTER DATABASE ADD STANDBY LOGFILE 'srl1.f' SIZE 104857600;
ALTER DATABASE ADD STANDBY LOGFILE 'srl2.f' SIZE 104857600;
ALTER DATABASE ADD STANDBY LOGFILE 'srl3.f' SIZE 104857600;
ALTER DATABASE ADD STANDBY LOGFILE 'srl4.f' SIZE 104857600;
Can anyone tell me a bit more a bit what this message is saying and explain the pros/cons of adding these standby log files to the standby database??

Thanks for reply..I am really confused by this both the primary and standby have the same redologs set up (3 groups of 2 logs) so dont understand why it is asking me to add 4 logs to the standby? are these the same or different from the normal redo log groups? why is this message only appearing when the control file is autbacked up?

Hi,
First thanks for your quick response.
The only thing that we have running in the database is a scheduled program how run every 3 min to switch the current log and he applied the archive log to the standby database!!!
It can be a session how is trying to do this "Alter database clear unarchived logfile...." ?
Thanks

Standby db: continue manualluy alter database register logfile

Add logfile group without shutting down first? (10g R2)

Can I add a logfile group without first shutting down the instance? I don't see any clear statement about this in my Alapati 10g Admin book or any Oracle 10g R2 docs. Citations appreciated. Maybe this is one of those "too obvious to publish" things. My guess is that Oracle 10g R2 is smart enough to know not to write to new logfile group members until it is fully created and available for use.
Thanks.

Hello,
Is the presumption that any "ALTER DATABASE" operation can be done online in 10g? Not Any, but Some, Yes.
For instance, the ALTER DATABASE ARCHIVELOG statement cannot be done online ( the Database should be mount ).
However about the ALTER DATABASE ADD LOGFILE statement, as previously posted, it can be done online. I've already done it on a running Production Database.
Just be careful to set the same SIZE as for the other Logfile Members.
Hope this help.
Best regards,
Jean-Valentin
