Maintenance of database activity
Hi friends,
We have planned for the maintenance of database using logical backups. but we are in the dilemma to choose the best way to use logical backups.
We have several patterns and multiple tablespaces in our db environment and a schema objects can reside on spaces of multiple tables.
Kind regards
Saida
A physical backup is a backup of the database or the individual data files.
A logic of backup is a backup of the database or individual patterns.
There is no backup to the table level space. A logical backup using export (exp or expdp) for a schema utilities would save the schema objects on all areas of storage that they reside in.
The question is: WHY a logical backup? Why not a backup Physics (for example with RMAN or a backup of cold to the BONE level) of the whole base?

You may need the parameter sql_trace set to true for the level of database tracking.
But I suspect you may be hitting a bug, suggest you to trigger a SR with Oracle support for more information on the crash of Eve.

I have cemabc_p and cemabc_s both primary and standby tnsping succuessfully.
Im sure I'm missing a step, if it didn't there was more information need... Let me knowOk
I guess that
connected to target database: CEMABC (DBID=4229695208) connected to auxiliary database: CEMABC (not mounted)
On the remote server's right? If so, it shows that RMAN was able to connect to the main server and the local static connection. So the problem is probably that the principal server cannot connect back.
You need an entry for the CLONE in your TNSNAMES file. ORA on both servers. Can you confirm this?
Can you post the listener.ora for clone entry?
I'm double control it
rman target backup_admin/temabc@cemabc_p catalog rman/qaabc@rmnabc
(Above is odd)
Mine:
rman target=sys/@recover2 auxiliary=sys/@reclone
I use SYS/password both for him to work.
Also, make sure that these are defined
listener.ora INBOUND_CONNECT_TIMEOUT_
= 120 sqlnet.ora SQLNET.INBOUND_CONNECT_TIMEOUT = 120 Restart the listeners later

(SID_DESC = (global_dbname = prdl) (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1) (sid_name = prdl)
You will have a static entry for RMAN duplicate...
Another example
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.2) (PROGRAM = extproc) ) (SID_DESC = (global_dbname = RECLONE.hostname) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.2) (sid_name = RECLONE) ) )
H3. Avoid delays
Add them to both servers
In listener.ora

SQLNET. INBOUND_CONNECT_TIMEOUT = 120Stop and start the listener
Use
lsnrctl status (to find a static entry)

Hello
on the 11g R2, how can we measure the activity of database?
Any question on any table?
I looked at transaction $ v and v$ global_transaction, but they give the current active transactions.
If they are not historicises?
Thank you.I hope that link below will answer your question (up to an extension):
http://www.mydbanotes.com/2010/05/transaction-history.htmlAnd if you want to get the whole story the last transaction, then AWR or Statspack is the tool for you and see the section of the load profile. Here, you will see something like this:

Hi all
We run on 'Oracle Database 11g Enterprise Edition Release 11.2.0.1.0'. We have 2 servers. A back-end database and an active dataguard. I have the new control Grid Enterprise Manager 11 g running on a separate server from Linux to control and manage my databases.
Policy is to have 4 hours dataloss. In the past (I managed everything with control grid 10, but things did not work, as well as with the new... problems with recovery catalog database and other..) I backed up my database primary with normal backup at 04:00 and a differential every 3 hours... The retention policy, it's that we should be able to return 3 days.
Now, I have installed the new grid control. I created a catalog of recovery on that server. The goal is to use the standby database (active) mark my backups using the recovery catalog. Is this possible?... If I want to set up the catalog of recovery on the day before databast it does not work... (oem said: "you can not configure the setting of recovery for a database catalog physics standbyu...") I can't also put in place a retention policy using my database pending... Databases should be in place 24/7... can't take them down!
Anyone suggestions how to proceed. Or should I keep my first backupping? It should be easy to possibly retrieve problems. Don't know if it's easier if I backup Primay...
Thanks in advance,
Kind regards
MarkDear user11140727,
If they both registered OK that you can back up the database now and I see the output as perfectly OK for me IF you have defined locations correctly.
If I were you I would like to backup the primary database rather than on the standby database, but I think that there is no limitation for the backup of the database on hold. You can also take a backup of the database on hold, but for me it's not logical.
You can take a full backup of the primary database and write metadata in the catalog of recovery that you can activate the option to block change tracking and start using the incremental strategy. This way you reduce the load on the database during maintenance hours.
Hope that helps.

Pavilion noteook 15-ab254sa: Wty: HP HW Maintenance off-site Support
Hello
I just bought a HP Pavilion laptop computer ab254sa form Currys PC world. I checked my status of the warranty on the HP site and it says Wty: off-site Maintenance HP HW - active Support. I can't find all infromation what type of warranty is that and what is the coverage... I would be very happy if someone can give me more details.
Thank you very much in advance, I really appreciate your help.
Best wishes
Asya
Asya1,
Guaranteed off-site means that send back you to HP for repair, or bring to an authorized to HP for repair service center.
If your laptop is under warranty, WILL NOT, you must pay for shipping if sent to a depot for repair.
There has been some cases where consumers are asked to pay for the shipping to the deposit. HP covers all port fees, so never pay to have your laptop repaired.
One thing, you may want to consider is 'a cover against accidental damage' for your laptop, provided by HP. This covers things like spills of liquid on the keyboard or a fall... Your HP standard warranty does not cover this type of damage, that electronic defects.
Kind regards
Louis
Enjoy your, laptop

Hi I need to purge the data. Our database is up to 330gig. Is there some sort of Protocol to do this for vfoglight 6.7?
Thank you
Scott
This is controlled by your settings of data retention, which have a very wide range of options.
Check on the administration server - servers-> data management, at the top of the screen, there are some simple global settings. By default, the data are kept in 100 years.
Also remember that the real data purging is something that occurs at the end of a several-step process and is controlled by a schedule of Maintenance of database for off-peak hours.

Please read the documentation of the requirement for Oracle APEX 5. Ensure that your environment meets these requirements. Upgrade your oracle database or other software if necessary components and then you can go right 4.1/4.2 to 5.0 update according to the above-discussed upgrade strategies in the above discussions.
Reference: https://docs.oracle.com/cd/E59726_01/install.50/e39144/pre_require.htm#HTMIG376
You should go for upgrade of the Oracle APEX of 4.1 to 5.x. Regression test your applications to remove if any errors introduced by upgrade. The kickoff of a new project to migrate your applications to universal theme.

But if I install the darabase even dbca on node secondary, all installed and executed successfully.
But in the two nodes even permissions, user oracle and oinstall group ID identified the same and $ORACLE_BASE and $ORACLE_HOME user owner oracle and oinstall user group.
A someone has encountered this problem and solved?
Thanks in advance!
Hello
you are using IBM AIX PowerHA for your database (active/passive) configuration. then you just install the binaries 'once' on one of the nodes. then coordinate with your operating system administrator to configure the fail the test scenarios.
for your question. before you start the database, make sure that there are no "orphaned" oracle process using the UNIX grep command:
$ ps - ef | grep ora
Kill the oracle of the hanging of the process to release the lock on the database file handle:
$ kill-9
I hope this helps.
Kind regards

How to create dashboards based on out-of-the-box dashboards of database?
Hello
I am interested in the creation of a couple of dashboards (Blocking (current) and blocking (history)) database based on the dashboards of database activity. (Current) block and activity. Blocking (history).
I'd appreciate anyone could share how do.
Thanks in advance

The General procedure is to create a new system module in Configuration/definitions as a user with the role of 'Dashboard Designer', then create an empty dashboard in the module using a page layout view.
Then you access the target database interface and use the Design tab to identify the view that you want to base your custom on dashboard. You would be deeply copy that view into your Dashboard System.
Then, you must satisfy the required context of entry of the dashboard copied into your empty dashboard and then add the copied display as a child of this dashboard.
If one of these steps is unknown to you, you will need to spend time with WCF to familiarize yourself with the tools and capabilities before start you this project. Database dashboards is more sophisticated and complex than in Foglight, then here is a difficult place to start. You can familiarize yourself with WCF using the tutorial using Foglight , or through simple projects like the construction of a dashboard customized to summarize LogFilter alarms.
Kind regards
