Do I need ASM for logical standby server?

I am using ASM in production, when I created physical standby for it, system asked me create ASM file system on it else it is not possible. My question is do I need ASM file system for logical standby too.?
Thanks

You can have the primary database on ASM and the standby on filesystem if you want.
You just need to set db_file_name_convert and standby_file_management. I have tested this will physical, but not logical standby.

Why FRA filling faster in logical standby server.

I have two standby servers one physical and one logical for my primary database. I have notice that on logical standby server the FRA is filling faster then physical standby server. Any one have some suggestions.
Thx

That is to be expected, because the logical standby not only creates archive logs on behalf of the transmission from the primary but also generates its own archivelogs on behalf of the filling (& archiving) of the local online logfiles. If you watch a logical standby applying, you may notice that the standby logs are getting archived and the online logs as well. That is significant for a logical standby and leads to (at least temporary) higher space consumption in the recovery area. Temporary, because the applied archive logs can get deleted (automatically, if you allow that).

Logical standby server stopped applying changes

Hi
I set up a logical standby database with database guard and it worked fine for some time. But recently I had to use it again and discovered that applying changes from primary database to secondary database just stopped working. I see in V$ARCHIVED_LOG one entry per day. If I restart the logical standby then the changes from primary server are also applied. But if I just make a change on primary server and even call 'alter system switch logfile' then I see an entry in V$ARCHIVED_LOG on primary server but not on standby server (BTW in general there are much more entries in this view on the primary server). I checked pairs of log files indicated by the parameter *.log_file_name_convert in standby server's spfile: their last changed date is always the same.
I will paste spfile of my standby server (dh5). Primary server name is dh2.

Hi,
Nice to hear you issue got resolved.
It is good practice to keep monitoring the progress of SQL apply on the logical standby on a regular basis.

Real time apply for logical standby

Hi
Oracle 11.2.0.3.0
I have a primary database orcl and logical standby database orcl_std.
Real time apply is enabled. I have standby redologs in both primary and standby sides and I`ve started recovery with below command:
ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
When I create a new table in primary database, I am unable to see it on standby database (Although real time apply is enabled)
However, when I switch log in primary, I can see the new table in standby database.
My question is, why realtime apply is not working in my scenerio ? I was expecting to see the new table immediately in standby database once it is created in primary database. Why am I supposed to wait for log switch in real time apply ?

Using Real-Time Apply to Apply Redo Data Immediately
http://docs.oracle.com/cd/E11882_01/server.112/e25608/log_apply.htm#i1022881

2.Try to check parameters mentioned in below link:

When to use Real Time Apply for Logical standby..!!

Hello All,
I have been trying many ways to speed up the archival on primary and improve sql apply on logical standby, but still we are getting about 45-50 mins of delay between primary and logical standby.
We wanted to have our transactions applied on logical standby within couple minutes. Which i guess wont be possible in async mode.
That's why i am planning to implement Real Time apply between primary and logical standby.
Now since both our databases are too far away from each other (Primary is in US and logical is in India) would it be recommended to implement real time apply in such scenario? And if implemented would it affect Primary DB Performance?
Also if there might be some packet loss or network hitch would Primary will try again and keep logical DB in Sync with Primary?
Any help or suggestions would be great.
Thanks.

yes, real time apply is recommended in your scenario.
however due to the geographical distance between your primary and standby; I would suggest to keep your standby in current mode - max performance ; ASYNC- itself. It would not affect the performace of the primary.
As long as you set the FAL parameters and configure tnsnames properly and ensure proper deletion policy for archivelog cleanup in primary ( so that it's not deleted before shipping if need be), you shouldn't find any problem with primary & standby synching.
Good Luck.
Cheers.

Query for logical standby

Hi ,
We have one logical standby database is running for our production database .
Now business require one more logical standby for reporting purpose
so during step for creating new logical standby we need to run
EXECUTE DBMS_LOGSTDBY.BUILD;
so is this will impact exsiting logical standby ? or we don't run this time this statemnet ?

Oracle 10gR2 Data guard physical or logical standby server?

Hi
We are planing to implement an Oracle 10gR2 data guard standby server for DR purposes, I found out that there are two type of standby server which is logical and physical standby server. I want to know which one is preferable? in term of complexity of setup and maintenance?
regards

Well it depends on what you mean by maintenance. I found the physical standby to be very little trouble at all ; however the logical standby has restrictions on it that the physical standby does not. In essence the physical standby merely digest archive logs; where as the logical standby uses logminer like functionality to process sql statements much like Oracle streams.
Hope that helps,

Open Mode for Logical Standby

HI,
I have a logical standby. It's v$database.open_mode shows READ WRITE
Q1. I am correct in assuming that the Database is only writable for tables that are not in the primary ?
Q2. Are the tables that are also in the primary, in effect in read only mode on the logical standby ? Am I able to see the mode of these tables to prove they are read only ?
thanks,
Jim

Hello;
User modification to tables on the Logical Standby has three possible settings:
ALL
STANDBY
NONE
You can check the mode using this query:
SELECT GUARD_STATUS FROM V$DATABASE;
If you try to insert data into a table and the mode is 'ALL' and you are not the SYS user you should get an error
ORA-16224
If you want users to modify non-replicated standby tables then you need to change the mode from its default of 'ALL'.
You can use DBA_LOGSTDBY_SKIP to find non-replicated tables ( the ones with skip rules ).
If you create new objects consider a naming convention that allows you to easily see the write status.

Prereq query for Logical Standby runs for days

Have had an SR open for a month that isn't getting anywhere, thought I'd check here and see if anybody has run into this.
We're looking at setting up a logical standby database, Oracle 11.2.0.3 on AIX running PeopleSoft.
There is a prereq query in the Oracle manual which is also run via the GC wizard to find tables without unique logical identifiers.
SELECT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_NOT_UNIQUE
WHERE (OWNER, TABLE_NAME) NOT IN
(SELECT DISTINCT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_UNSUPPORTED)
AND BAD_COLUMN = 'Y';
My problem is that the darned thing runs for 5.5 days.
The view in that query runs the function logstdby$tabf, which runs the following SQL over and over and over and over:
SELECT * FROM LOGSTDBY_UNSUPPORT_TAB_11_2B
Each time it runs the LOGSTDBY_UNSUPPORT_TAB_11_2B query is about 8 seconds. Run it 100,000 times and that adds up. Looks like the big problem in that query is full table scans of TAB$ and COL$.
Anybody seen it? Anybody fixed it?

Good suggestion - in 15 minutes you got farther than support did in 2 weeks.
Rather than remove the sub-query, I can change it into a minus, which is functionally equivalent to the original but changes the executions on DBA_LOGSTDBY_UNSUPPORTED from many times to just once.
select owner, table_name from dba_logstdby_not_unique
where bad_column = 'Y'
minus
select distinct owner, table_name from dba_logstdby_unsupported;
The top part of the query still takes 9.5 hours to run though, with the time now being spent the following SQL which is called from the function logstdby$tabf which is called from the view DBA_LOGSTDBY_NOT_UNIQUE :
SELECT * FROM LOGSTDBY_SUPPORT_TAB_11_2B
Sorry for not putting that in the original post, but I want the original query to run if possible so the GC wizard will work - and I didn't want to clutter up the question.

If you want to have Oracle Applications Server 10g, you need to install it in a NEW ORACLE_HOME (Refer to Note: 233436.1 for more details).
i am still confused for my AS version , how can i clarify that To determine the version, issue:
UNIX: $ORACLE_HOME/Apache/Apache/bin/httpd -version
Windows: %ORACLE_HOME%\Apache\Apache\apache.exe -version
main components which i am using with my current AS are forms and reports serverOracle Developer 6i (Forms and Respports) are NOT part of Oracle Applications Server installation, it is installed under 8.0.6 ORACLE_HOME.
can they be independently upgraded?Yes, see my answer to the first question in this reply.

Why my cronjob for primary/standby server not work, but worked at prompt

I have redhat linux version 5, oracle servers 11gr2.
I have cronjobs to monitor tablespace usage and alert logs.
However they not work at the cron job, but if I execute them at the command prompt, it worked.
What might be the problem?
example of the cron script:
Head of the script:
#!/bin/bash

Any guru help?

Hello;
Generally this is an environment issue.
The script works at the command prompt because when you signed on your user picked the environment settings from a profile, for example .bash_profile.
A crontab job has no environment. That is why you call hydev_env near the beginning of the script. So something of some things are missing from your env file mostly likely.
What I do is keep an environment file for each database at a location like this :
/u01/app/oracle/dba_tool/env ( /u01/app/oracle/dba_tool/env/PRIMARY.env )
The file PRIMARY.env is <database_name>.env
What I keep in it is everything I need that a background job like crontab would need :
ORACLE_BASE=/u01/app/oracle
ULIMIT=unlimited
ORACLE_SID=PRIMARY
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.2
ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
LIBPATH=$LD_LIBRARY_PATH:/usr/lib
TNS_ADMIN=$ORACLE_HOME/network/admin
PATH=$ORACLE_HOME/bin:$ORACLE_BASE/dba_tool/bin:/bin:/usr/bin:/usr/ccs/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:/usr/lbin:/GNU/bin/make:/u01/app/oracle/dba_tool/bin:/home/oracle/utils/SCRIPTS:/usr/local/bin:.
export TERM=vt100
export ORACLE_BASE ORACLE_SID ORACLE_TERM ULIMIT
export ORACLE_HOME
export LIBPATH LD_LIBRARY_PATH ORA_NLS33
export TNS_ADMIN
export PATH
export MAILTO=
Important If you are not sure of a setting on your system type "env" at a Linux prompt while logged on as the user where the script works. Change as needed in your .env file.
Here a script I call from crontab to check tablespaces
#!/bin/bash
if [ "$1" ]
then DBNAME=$1
else
echo "basename $0 : Syntax error : use . quickcheck <DBNAME> "
exit 1
fi
# Set the Environmental variable for the instance
. /u01/app/oracle/dba_tool/env/${DBNAME}.env
$ORACLE_HOME/bin/sqlplus /nolog <<EOF
connect / as sysdba
@/u01/app/oracle/dba_tool/bin/quickaudit
EOFNotice how I pass the db name as a parameter to the script so I can use the script with several database without changing it.
/u01/app/oracle/dba_tool/bin/quickcheck.sh PRIMARY
The crontab to make this run daily at 5:12 am is :
12 05 * * * /u01/app/oracle/dba_tool/bin/quickcheck.sh PRIMARY > /tmp/quickcheck.out

What are advantage and disadvantage for Physical Standy and Logical Standby

HI,
What are advantage and disadvantage for Physical Standy and Logical Standby configuration?
Thanks
Ken

Logical standby database
The key advantage for logical standby databases is that they're opened read/write, even while they're in
applied mode. That is, they can be used to generate reports and the like. It is indeed a fully functional
database. Also, additional indexes, materialized views and so on can be created.
However (this being a disadvantage) not all datatypes are supported.
Oracle (or more exactly the log apply services) uses the primary database's redo log, transforms them into
SQL statements and replays them on the logical standby database.
Physical standby database
A physical standby database is a byte for byte exact copy of the primary database. This also means that
rowids stay the same in a physical standby database environment.
Oracle (or more exactly the log apply services) uses the primary database's redo log to recover the
physical database.
A physical standby database might be opened read only; however, the received logs are in this case not
applied. When the logs are applied, the database is not accessible (it is then in a managed recovery state).

Why we need SSL Certificates for configuring App Server in Sharepoint

Hi Support,
We are planning to have a separate server for Apps, while configuring the server its asking for certificate. The main scenario is while configuring server inside the same firewall why we need SSL for configuring.
Could you please let me know the reason why we need SSL for configuring App Server.
Thanks in Advance,
Regards,
Pradeep

Hi Pradeep,
SSL (Secure Sockets Layer) is a transaction security standard that provides encrypted protection between browsers and App Servers. When SSL is enabled for an App Server, browsers communicate with the App
Server by means of an HTTPS connection, which is HTTP over an encrypted Secure Sockets Layer. HTTPS connections are widely used by banks and web vendors for secure transactions over the web.
Secure Sockets Layer is a requirement for web applications that are deployed in scenarios that support server-to-server authentication and app authentication. This is such a scenario. As a prerequisite
for configuring Task Synchronization, the computer that is running SharePoint Server must have SSL configured.
