7.3 to 9i data guard

Using Oracle 11 g Data Guard disaster recovery

Hi, can anyone answer if Oracle 11 g Data Guard by itself provides an option for making/switch between the main bases and emergency (back and forth) disaster and as a restoration solution, seamlessly? Here's the scenario:
1. two databases (active and reserve)
2 put it to sleep (make primary with read/write)
3. restore to the original database

Data Guard has two transitions of role... Failover and the digital switchover.

Passage to the fact exactly what you describe. You can switch to standby and vice versa. However, this will not work unless the primary and the standby are available. If you will not be able to perform an operation of swichover when you have a failure in the main data center that makes the primary db not available.

Failover will be the day before in a primary for the moments where the primary origin is not available. Unlike the digital switchover, failover is one-way. There is no 'restoration' of failover. If you do not failover, then once the old Center of main data is operational again and you can get the former primary database up, you must restore from the first news and make a watch for the first new. At this point, you can then make a pass to come back and run in the original data center.

ORACLE DATA GUARD

Hello everyone
Je challenge me make a lab for learn ORACLE DATA GUARD technically, my question is what is possible to make this work between two VM Machine,
If Yes so What are the Prerequisites at the end of success in this challenge
thnx

It is quite possible. I myself learned per virtual machine.

Data Guard archive political deletion log

Hi all
I configured the data guard with 2 bases Eve in oracle 11g.
I want to use rman to delete archives on all servers.
I have configured no FRA, no recovery catalog.
My question is:
If I delete waiting til sequence # 1627 and on primary sequence til = # = 1620 or vice versa this would cause problems for Data Guard.
I say delete until the different sequences # on primary and standby cause problems for synchronization?
Thank you

So if I understand delete archivelog to sysdate - or delete archivelog all completed before sysdate n is not the archivelog deletion policy you put on RMAN?

She depends on it. The note was made at the base of the MOS document how ensure that RMAN is NOT delete archived logs that have not yet shipped to standby mode (Doc ID 394261.1)

Delete archivelog to sysdate - depends on all of the deletion policy. If the deletion policy is set on "applied pending all", then it does not delete the archives, if they are not applied on the day before. If the deletion policy is set to none, then it does not check if the archive is applied on the eve and deletes them directly.

Last Archive generated on primary:

SYS@oraprim > select max(sequence#) from v$ archived_log;

MAX(SEQUENCE#)

--------------

114

Last check-in applied in mode ensures:

SYS@orastb > select max(sequence#) from v$ archived_log in case of application = 'YES ';

MAX(SEQUENCE#)

--------------

109

Delete policy set to NONE on primary:

RMAN > show archivelog deletion policy;

using the control file of the target instead of recovery catalog database

RMAN settings for database with db_unique_name ORAPRIM are:

CONFIGURE THE NONE ARCHIVELOG DELETION POLICY;

RMAN > delete archivelog until 'sysdate;

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID = 60 type of device = DISK

You sure you want to delete the items above (enter YES or NO)? NO.

It is the removal of primary archives that have not yet been applied on the eve.

Delete policy 'APPLIES ON STANDBY ALL' value on the primary:

It checks if the archive has been applied on the day before. As the 110 to 114 sequence is not applied in the waiting, the archives are not deleted on the primary.

Hope that gives you a clear picture of how it works.

Data Guard environment, how time will need to use standby Database

Dear experts,
OS - Windows server 2012
Oracle Version - 11.2.0.1.0
The size of the database - 500 GB
I have the plan to implement Data Guard. The database size is 500 GB.
Please find below the question
(1) when the database is harnessed for how long take use waiting for database so immediately or a few minutes?
(2) when the server went down how long then to connect with the server backup immediately or a few minutes?
I'm new to the data protection environment. Kindly help me

Hello;

I can perform a failover or a failover with Data Guard Broker in about 20 seconds. If I don't use a broker, it takes about 3 minutes.

Quick start failover takes less time. Time will depend on the material, etc. of configuration options.

Best regards

Data Guard - allocation of licenses and other fundamental questions before setting it up.

Hi all
Please allow me to submit some questions about Oracle Data Guard.
There are 2 databases 'authorized and ready ':
-a single instance of the "alfa", Oracle Enterprise Edition 10.2 database,
-"bravo", Oracle 10.2 Enterprise Edition, Real Application Clusters database
I have to "align" congratulations to alfa on a daily basis, so that--in case of failure of the main 'alfa' site - recovery is possible change to the site "bravo."
(1) even if we can afford a loss of data corresponding to the period little uttered at the end of the last daily alignment (no need to 'transactional' alignment between the two databases), I assume that the best approach to meet this need in terms of efficiency and manageability consists on two databases including in a Data Guard configuration.
Am I wrong?
(2) in particular, the physical implementation of the standby database must be preferred over logic, because that "simpler and faster" in this case. Am I wrong?
(3) only the Data Guard configuration require
(a) additional licenses?
(b) additional material/software resources for host machines?
(5) the release of two databases must be equal to the specific to the component version number (10.2.0.1, for example)? Or, for example, is a 10.2.0.1 able to work with a 10.2.0.3 db db in the Data Guard configuration?
Thank you very much in advance!

Hello

Am I wrong?

You have reason, physical hosting it good thing. For the most part, you will get impact with until or unless data loss because of some problems of network (or a configuration problem)

(2) in particular, the physical implementation of the standby database must be preferred over logic, because that "simpler and faster" in this case. Am I wrong?

Logical standby is a little different from the physical standby mode

(3) only the Data Guard configuration require

(a) additional licenses?

(b) additional material/software resources for host machines?

Data features come with Enterprise Edition - perhaps for the active database "cost of the additional license.

https://docs.Oracle.com/CD/E11882_01/license.112/e47877/editions.htm#DBLIC109

(5) the release of two databases must be equal to the specific to the component version number (10.2.0.1, for example)? Or, for example, is a 10.2.0.1 able to work with a 10.2.0.3 db db in the Data Guard configuration?

Good level to maintain the same level of oracle binaries / patches and still the support of heterogeneous DG

Data Guard - RMAN removing archive log

Hello
I ' v DataGuard with physical standby.
I do a backup only on the primaries. Both sites have ther separate backup systems.
I ' v FRA and configured archivelog deletion with RMAN configuration:
on primary: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
standby: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;
It works fine but I think what if scenarios and I'v qestion on best practices for backup after the transition of role management. Let's say that for some reason, as i'v in switch mode sleep for a few days and the backup will be posible to watch (now primary) database. What would be the steps/reconfiguration appropriate to do?
1 should I reconfigure RMAN?
change of new primary to: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
change back to sleep again: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;
2. make full backup

Hello

1. you can refer to the oracle documentation: http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmconfb.htm#CHDCFHBG

section: "all archived Redo Log deletion policy."

Document provides the best algorithm to analysis of work

You can use the CONFIGURE ARCHIVELOG DELETION POLICY BACKED UP integer TIMES TO DEVICE TYPE command to allow a policy of removal of archived newspaper. This configuration specifies that archived newspapers are eligible for deletion only when the specified number of archived log backups exist on the specified device type.

If the deletion policy is configured with the BACKED UP integer TIMES clause, then a BACKUP ARCHIVELOG , the command copy newspapers, unless integer already exist on the specified device type backups. If integer are backups of logs, then the BACKUP ARCHIVELOG command ignores the newspapers. In this way, the deletion of archived newspaper policy works as a default NOT BACKED UP integer TIMES clause on the BACKUP ARCHIVELOG command. Note that you can override the deletion policy by specifying the FORCE option on the BACKUP command.

The deletion of archived newspaper policy has also options specific to an environment Data Guard. , then RMAN can delete logs after they have been applied to all destinations remote mandatory. If you specify SHIPPED TO STANDBY , for example, then RMAN can remove log files when they were transferred to all destinations of mandatory relief.

2. the paper provides good information, just to check and decide easily based on the functionality of the database role you can configure.

It will be useful.

Possible to have some project documents in a CDP that is used for Data Guard and other PDB files don't not ITIS?

No, not in the current version. You must use the PDBs als for DG or nothing.

Data Guard and auditor of the Apex

Hi all
I seem to be unable to understand the configuration of parameters for protective Apex listener when connecting to a database.
We have a lot of servers of databases (without data guard) and we use the command line Wizard to generate the configuration file. It's straigthforeward and
easy. We enter the server, port, and Service_name and it works.
But for a guard database, there are two servers and I seem to be unable to set it in the right way. After doing some research I came across the parameter apex.db.customURL which should solve the problem.
I removed the references to the server, port, and Service_name and put the key in.
The result were errors of connection due to some incorrect port settings.
SEVERE: The pool named: apex is not properly configured, error: IO error: format invalid number for the port number
oracle.dbtools.common.jdbc.ConnectionPoolException: the pool named: apex is not properly configured, error: IO error: format invalid number for the port number

Keep the references the server name, port and service. No need to delete.

The result were errors of connection due to some incorrect port settings.

What Miss me?

You must create two entries in the configuration file "defaults.xml" for your ADR (formerly APEX Listener).

One for db.connectionType and, secondly, for db.customURL, for example:
```
customurl
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=
(ADDRESS=(COMMUNITY=tcp.world)(PROTOCOL=TCP)(HOST=DB-ENDUR)(Port = 1520))
(ADDRESS=(COMMUNITY=tcp.world)(PROTOCOL=TCP)(HOST=DB-ENDURK)(PORT = 1521))
(LOAD_BALANCE=off)(FAILOVER=on))(CONNECT_DATA=(SERVICE_NAME=ENDUR_PROD.VERBUND.CO.AT)))
```
Reference: http://docs.oracle.com/cd/E56351_01/doc.30/e56293/config_file.htm#AELIG7204

NOTE: After you change the configuration file, don't forget to restart independent ADR / Java EE application server support if ADR is deployed on one.

Also check if your URL for a JDBC connection is working properly and if there are any questions, you can turn on debugging for ADR:

Reference:
- http://docs.Oracle.com/CD/E56351_01/doc.30/e56293/trouble.htm#AELIG7206
- http://docs.Oracle.com/CD/E56351_01/doc.30/e56293/trouble.htm#AELIG7207
Directed by Tony, you should post the ADR related questions to the appropriate forum. Reference: ADR, SODA & JSON in the database

You can also move this thread on the forum of the ADR.

Kind regards

TAF TNS entry for active data guard

Hello world
Need your advice on the configuration of the TNS entrance side transparent client failover of the DB in waiting in a Data Guard configuration active?
Normally, I create a service manually and configure this service to start or stop according to the change of role of database. Then have personalities of the two sites in the entry of TNS (example below).
TEST =
(DESCRIPTION =
(FAILOVER = ON)
(ENABLE = BROKEN)
(LOAD_BALANCE = TRUE)
(ADDRESS = (PROTOCOL = TCP) (HOST = VIP1-SITE1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP) (HOST = VIP2-SITE1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP) (HOST = VIP1-SITE2)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP) (HOST = VIP2-SITE2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = TEST)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 20)
(TIME = 2)
)
)
)
I learned this method of-> http://uhesse.com/2009/08/19/connect-time-failover-transparent-application-failover-for-data-guard/
Is there a better way to do this? Can we achieve this using an AMT only?

I think I found the answer. According to the document oracle practices best client failover, the service can be configured to start automatically on the standby server when the role of the db is changed. This can be achieved by creating a service with srvctl with option '-l PRIMARY' on both sites

For example:

Main cluster: srvctl add service d Austin s oltpworkload r - ssa1 ssa2 ssa3, ssa4-l primary SCHOOL - q TRUE EI SESSION m BASE w 10 - z 150

Cluster of relief: srvctl add service d Houston s oltpworkload - r BSR1, ssb2, ssb3, ssb4 - l PRIMARY - q PURE EI SESSION m BASE w 10 - z 150

Documentary link--> http://www.oracle.com/au/products/database/maa-wp-11gr2-client-failover-173305.pdf

Also the entrance to the AMT must be created with two descriptions, one for primary and one for standby

TNS_DG =

(DESCRIPTION_LIST =

(LOAD_BALANCE = OFF)

(FAILOVER = ON)

(ENABLE = BROKEN)

(DESCRIPTION =

(ADDRESS_LIST =

(LOAD_BALANCE = ON)

(ADDRESS = (PROTOCOL = TCP) (HOST = vip1-primarydb)(PORT = 1521))

(ADDRESS = (PROTOCOL = TCP) (HOST = vip2-primarydb)(PORT = 1521))

)

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

(FAILOVER_MODE =

(TYPE = SELECT)

(METHOD = BASIC)

(RETRIES = 20)

(TIME = 2)

)

)

)

(DESCRIPTION =

(ADDRESS_LIST =

(LOAD_BALANCE = ON)

(ADDRESS = (PROTOCOL = TCP) (HOST = vip1-standbydb)(PORT = 1521))

(ADDRESS = (PROTOCOL = TCP) (HOST = vip2-standbydb)(PORT = 1521))

)

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

Oracle will consider the creation of a day 2 hands on the documentation for Data Guard?

Hello
Oracle will consider the creation of a documentation of son of hands 2 day for Data Guard?
There is already an OTN 2 day of CARS and performance tuning documentation.
Thank you

Updated - she sent the link to this topic for the Product Manager Data Guard. As a result, Oracle may or may not consider creating 2 days hands on Data Guard documentation, but no doubt they consider at least considering creation day 2 hands on the Data Guard documentation.

Data Guard - journal not attributed to primary school

Data Guard
==========
When I run
Select count (*) from v$ archived_log in case of application = 'NO' on the primary, I had more than 3000 results.
the day before I got only one (but that another question I am trying to solve with the help of the Oracle).
is that normal or what? its something about a new database that you install for the study, but its another thing on a database that worked for awhile and I recently presented to it.
one thing is sure that the archive log is shipped on the eve and applied in real time. and also switch are fine (SUCCESS). the mark in the data manager Guard gives also the success, but wan't the right answer is '0' or no line selected, right?
Thank you.

Hello

The fact that your query returns more than 3000 is not necessarily say that there is no problem because when you query v$ archived_log it will always report "N" for the destinations of local newspaper archive, you should check for APPLIED only = "" and standby_dest = 'YES '.

If your update query should be:

Select count (*) from v$ archived_log in case of application = 'NO' and standby_dest = 'YES '.

Data Guard Performance: apply Lag

In Cloud control there is a measure called "Lag (seconds) apply" under a group called 'Data Guard Performance '. I created an alert on this metric rule. However, I want to know what thresholds are defined for this measure, if I look under the supervision of models. He isn't here. There are also a number of other Performance measures of custody of data that is, I can't find or add in templates. Can anyone help?

From the home page of a database on hold, you can navigate to the (Oracle database > surveillance >) metrics and Collection settings page and select all the metrics view to check or set thresholds for (Data Guard Performance) metrics apply Lag. Note that by default, no limit is set for this measure.
