Time zone difference between primary and physical standby

Dear Team,
We have Primary database server (with EST Time zone) and physical standby (with PST time zone), in case of switch over/fail over to physical standby
what are the major impacts.
Is it mandatory to be in time sync?
Thanks in advance
Aj

CURRENT_TIMESTAMP
04-FEB-10 10.22.20.444692 AM +05:30
( above is same on primary and standby)
SQL> select systimestamp from dual;
SYSTIMESTAMP
03-FEB-10 08.52.46.934125 PM -08:00
(above is 3hr diff from primary and standby)It is 13hrs difference
One is around Indian subcontinent and other should be in US western region ?
Systimestamp is the timestamp of the OS of the server and hence the difference and the sysdate value will be from systimestamp and if the applications uses SYSDATE then there can be an issue...

Data Guard Archive Log Latency Between Primary and Physical Standby

How can I get the time it takes (latency) for the primary instance to get an archive log over to the physical standby instance and get it "archived" and "applied". I have been looking at the V$ARCHIVED_LOG view on each side but the COLUMN "COMPLETION_TIME" always shows a date "MM/DD/YY" and no timestamp. I thought the DATE datatype include data and time. Any ideas on how I can get the latency info I'm looking for?
Thanks
Steve

the COLUMN "COMPLETION_TIME" always shows a date "MM/DD/YY"
and no timestamp. Did you try using TO_CHAR ? e.g.
to_char(completion_time,'dd/mm/yyyy hh24:mi:ss')

Data guard synchronization after link down b/w primary and physical standby

Hi All,
I have configured data guard on oracle 11gr2 db. Normally switchover between my primary and physical standby happens smoothly and the Apply lag would be zero. Recently We had to test a scenario when the network link between Primary and Physical standby is completely down and Physical standby is isolated completely for more than half an hour.
When we brought up the link every thing worked smoothly but apply lag started increasing from 0 to around 3 hrs. And then it started reducing to 0. Currently Apply lag and transport lag shows 0.
But is this normal behaviour of oracle data guard that when the link between primary and physical standby is completely down, It requires 3-4 hrs for resynchronization ??? Even when during isolation, there were very few transactions happend on primary database ??
Are there any documents available for this scenario??
Thanks

Hi, after the link is up, if there were some transactions and produced archive logs it's normal to take some time for resync. To check if 3-4 hours is normal or not, you can repeat the scenario and this time check
- how many archivelogs does primary produce in this period.
- after the link is up, does archivelog transfer immediately starts from primary to standby? Is primary able to send these archivelogs parallel?
- Is there anything wrong with the apply process?
check primary & standby alert log files, and run this query on standby to check the transport and apply processes:
SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;
regards

Dataguard showing 8hr lag between logs between primary and physical

I'm showing around 8 hrs between when my primary sends the redo to my physical standby. My protection mode is at maximum performance. I'm wondering if I should change the time that my primary sends the redo to something shorter? Is this ok to have such a span between when the primary sends the redo?
thanks.

Are you saying it's taking 8 hrs to transfer a log to the physical standby or 8hrs to apply that log?
I suspect its the latter (unless you have huge logfiles and a slow network!) so yes you can tune the delay, its the DELAY parameter in the log_archive_dest_n paramater. Check to see what you have that set to.
As to whether 8hrs is ok is entirely dependent on your business and your service level agreements, so you'll have to answer that.

Backing up primary and physical standby

We have a DG setup with a single instance primary node and a physical standby db. They both use their own FRA's and their own disks. Nothing is shared. Also the datafiles use OMF on both the db's. My questions are
1. Can i register the primary with the rman catalog and still backup the standby?
2. Should i backup the archive logs on primary? If so what rman settings should i use on both for the archive logs?
3. We wanted to back up both the dbs as it will be faster to restore since we wont have to convert filenames (cause of OMF) when we have to resotore backup taken on primary to standby or vice versa.
Any advise related to this scenario is highly appreciated.
Thanks.

Hi All,
you should have same rman format setting and log_archive_format on primary and standby database >to avoide any confusion at the time of restore. if you have different log_archive_format on standby then >primary, you might have to rename your archivelogs from standby to log_archive_format on primary.It is not required to have same log_archive_format for primary and standby database.
The database can be restored and recovered successfully even if the format is different.

ARCHIVELOG deletion on primary and physical standby

Hi,
We have a primary and a physical standby database running Oracle 11.1.0.7.0 software on Red Hat Enterprise Linux x-64 bit OS. I will be using backup software
to only backup the primary database and do not have the backup software for the standby server and database.
We need to backup archived redo log files from primary site and delete the ones which are more than one month old. These archived redo log files will be applied from primary to standby database as and when the log switch occurs.
Can anybody please let me know if the following steps can be used:
Details are:
primary database name - sun (machine name is node1)
standby database name - drsun (machine name is node2)
On node1 as oracle user:
$ cat /export/home/oracle/rman/scripts/cleanup_rman_arch_sun.sh

exit
$ cat /export/home/oracle/rman/scripts/cleanup_rman_arch_sun.rcv
allocate channel for delete type disk;

$ crontab -l
# Delete the archived redo log files at 11:00 PM on the first day of every month
00 23 1 * * /export/home/oracle/rman/scripts/cleanup_rman_arch_sun.sh

Hello;
Welcome to the forums. ( By physical Standby I assume Data Guard )
The short answer is it should work. I noticed this :
/cleanup_rman_arch_drsun.rcv
crosscheck archivelog all;
sql "alter system switch logfile";
delete noprompt expired archivelog all;
change archivelog until time 'SYSDATE-1' delete;I see no reason for the "alter system switch logfile". In fact you can do something very simple on the Standby :
$ORACLE_HOME/bin/rman target / catalog <user>/<password>@<catalog> << EOF
delete noprompt ARCHIVELOG UNTIL TIME 'SYSDATE-1';
exit
EOFThis assumes you have doing a backup with RMAN on the Primary ( tested on 11.2.0.2 ) and have this set on the Primary :
CONFIGURE ARCHIVELOG DELETEION POLICY TO APPLIED ON ALL STANDBY;
If you are deleting Archive without using RMAN first then yes something like this ( But I would try to use RMAN and not delete using another method )
echo `date`
echo "Runnung RMAN archive crosscheck"
$ORACLE_HOME/bin/rman <<EOF
connect target /
crosscheck archivelog all;
delete noprompt expired archivelog all;
exit
EOF
echo `date`

Dataguard 9iR2 using same SID for primary and physical standby issues

Hello, I have been following the Creating Physical Standby Database document from Oracle setting up a physical clone for a 9iR2 database on Solaris 9 environment between two identical workstations. I want to databases to have the same SID for relatively seemless failover however the redo logs are not pushed to the physical clone. when I switch a logfile on the primary and then query v$archive_dest on dest_id=2 I get a status of ERROR and the ERROR is the ORA-12154 TNS service name error.
Here is a summary of my setup:
Primary - SID = PROD1, located on WS001
Clone - SID = PROD1, located on WS002
SPFILE settings on Primary:
*.db_name='PROD1'
*.dg_broker_start=true
*.fal_client='PROD1_node2'
*.fal_server='PROD1_node1'
*.log_archive_dest_2='service=PROD1_node2 optional lgwr async=20480 noaffirm reopen=15 max_failure=10 delay=30 net_timeout=30'
tnsnames.ora on Primary:
PROD1_node2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = WS002) (PORT = 1521))
(CONNECT_DATA =
(SID = PROD1)
listener.ora on secondary:
PROD1_node2 =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = WS002) (PORT = 1521))
SID_LIST_PROD1_node2 =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /export/oracle/oracle_9.2/PROD1)
(SID_NAME = PROD1)
Any input would be appreciated. I can provide whatever else you might need. I thought this was the most pertinent to this problem.
Thanks.
Jim

I have been looking at the sqlnet.ora files for the two databases
for WS001:
Names.Default_Domain = WS001.example.com
Names.Directory_Path = (TNSNAMES, ONAMES,HOSTNAME)
for WS002:
Names.Default_Domain = WS002.example.com
Names.Directory_Path = (TNSNAMES, ONAMES,HOSTNAME)
I cannot connect with sqlplus from WS001 to WS002 on the other machine.

Primary and Physical Standby databases hanging on sqlplus shell command...

I am primarily a java developer that has had the task of oracle dba thrust upon me due to circumstances that are beyond my control. In the QA lab we have two oracle 10 g release 1 instances running. They set up in a dataguard configuration: one is the primary and the other is in a physical standby.
Last week I noticed that the disk space on the primary database was at 100%. After some investigation I discovered that a good deal of the files taking up space on the box were log files and the best solution that I could think of would be to delete all old archive files. So I deleted the old archive files that were at least two weeks old using RMAN.
During this week the database started to shutdown automatically. The QA associate restarted the database twice using the ‘STARTUP’ command from sqlplus. Additionally, the standby database began to have issues: when login in to sqlplus the application would just hang: no ‘SQL” prompt or anything. Finally today the primary database has also begun to hang in a similar manner.
I have looked at many of the trace files and alert logs but haven’t been able to really discern what the real problem is with the database and the proper rectification for the database. Does anyone have a clue into what is going on? If someone could even point me in the right direction it would be greatly appreciated.

Guessing that your flash recovery area is full, archiving is stopped so the instance appears to hang.
Do you see messages like so in the alert log:
You have following choices to free up space from flash recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
   then consider changing RMAN ARCHIVELOG DELETION POLICY.
2. Back up files to tertiary device such as tape using RMAN
   BACKUP RECOVERY AREA command.
3. Add disk space and increase db_recovery_file_dest_size parameter to
   reflect the new space.
4. Delete unnecessary files using RMAN DELETE command. If an operating
   system command was used to delete files, then use RMAN CROSSCHECK and
   DELETE EXPIRED commands.

ASM on primary and physical standby on normal filesystem

Hi
I have seen he white paper by oracle on migrating a database to ASM with minimal downtime using ASM for a physical standby my requirement is reverse.
I need to have a ASM for a primary database but no ASM for standby database.
How do we set the parameter db_file_name_convert
regards
Hrishy

db_file_name_convert covers the folder path for the files. I don't think, there will be issue.
If we use rman, it will use the folder path per db_file_name_convert and retain the old file names. OMF naming will apply for the new files.

how come this?
i have followed complete procedure according to docs....
all 34 arch logs have been applied..
is this happen after creating standby database???
thanks and regards

Vikrant,
If you have applied all the logs
select applied, count(*) from v$archived_log group by applied; -- Please make sure you have all the logs applied successfully
shutdown immediate;
startup force nomount pfile='....' or startup force nomount;
alter database mount standby database;
-- this will activate your standby database and your should be able to open it without any problem; Primary database will be up and running as well.
alter database activate standby database;
alter database set standby database to maximize performance;
alter database open;

Time zone problem between mac and windows

i'm running os x snow leopard on one partition and windows 7 on another on a 2008 mbp. whenever i log into windows and then get back onto mac, my time is completely off. i can temporarily fix it by removing the local time file, which resets it, but every time i log into windows and back i get the same problem. i've tried turning off the automatic time zone, tried turning off auto everything and just setting the time myself and it always goes back to being messed up after a trip to the windows partition.
anybody got a fix?

For windows users can you create a connection key in Windows machine and send the same.

Difference between logical and physical SQL

Hi all,
I created a dashboard prompt and added some columns from the dimensions and one column from the fact table.
When I run the report in the dashboard and filters using the prompts,I see in the logical sql that all the filters have been applied to the report, but when I check the physical SQL only the filters on the dimensions columns have been applied.
I don't see the filter on the columns from the fact table.
Is there any reason for that?
Regards

I could figure out what was the issue.
My fact table was using a different MV as source table.The fact table column I was using in the prompt was not mapped correctly to the one in the MV.
