• Arc0: caveat.  Wrapped sequence of journal in the name of the file archive

  Hello
  
  I'll have my production (Oracle 11 g 1 material) database in windows 2003 server.

  1 might. someone the reason and how to solve this problem?
  2. also, I want to know the limitations of %s and %S in LOG_ARCHIVE_FORMAT?
  
  My log_archive_format has the value chain ARC%S_%R.%T

  Hello

  Can you tell me the difference between %s and %S for example? and how to check the log file archive even already existing?

  The use of uppercase letters for the variables (for example, %S) will cause the value to be set and full length on the left with zeros. So that said, there is a possibility when after filling of the letters name of archive may get conflict with other existing archive the log file name (this is the only possibility in the very large production generating a high number of archiving daily newspaper)...

  BOF doc:

  Sequence number of the log %s

  Sequence number of the log %s, zero-filled

  Salvation;

  Control post Radrigez, link control. I belive there is no account of this setting, at least rman notes do not mention any value

  %s backup the value number. This number is a counter in the control of the file that
  is incremented for each backup set. The value of the counter starts at 1 and is
  unique for the lifetime of the control file. If you restore a backup
  control file, then duplicates can lead.
  In addition, CREATE CONTROLFILE Initializes the counter to 1.

• Company of Mgr 12 lost connection to the RAC databases after the restart of the EM

  
  This last weekend, we restarted our main production RAC database (name = prod, instances = prod1 and prod2) and our certification test RAC database (name = cert, instances = cert1 and cert2).

  These databases have been put up and work OK as a target in MS 12 c for a few months.  However, I was not able to connect to these databases into EM yesterday, so I rebooted the server database repository EM both of EM application server.

  As of today, I can connect to the web console of EM successfully, and I can bring up our databases not CARS.  But if I try to put in place either of our CARS (prod or cert) databases, or if I try to put in place a specific instance prod1, prod2 or cert1, cert2, I get errors like this:

  IO error: the network adapter could not establish the connection

  The connection descriptor was (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = tcp) (HOST = nhaoranla - oracle.nha.local)(PORT=1521))) (CONNECT_DATA = (SID = cert1) (SERVER = DEDICATED)))

  The server nhaoranla where cert1 database instance.  We use the standard port 1521 for all targets.

  Two CARS of prod and cert authorities are running, and user applications are able to connect to the two bodies.

  I have not changed anything in EM.  The only difference with last week's restart.

  I tried to restart the server applications EM once again, but that solves nothing, I get the same error.

  Any suggestions or bugs that are known for this problem would be appreciated.

  Figured out what the problem was... TCP error message indicated it was looking for nhaoranla - oracle.nha.local , but I nhaoranla-oracle in/etc/hosts on the server to OEM applications.

  Lesson learned... If you add databases to the OEM through node discovery, initially, it could work, but it will fail when you restart your server OEM if you don't have good (complete) entries in/etc/hosts.

• Backup and the RAC database

  Hello
  
  I was wondering that if I have a (10g) 2-node RAC database, the database is in noarchivelog mode. Is it possible that I can do a cold upward on one instance while the other instance still works?
  
  Thank you
  Chau

  It is not a (consistent) backup cold if the other node is still in place and available. When you try to back up the other node, the CNS will not work with the current SNA. Maybe you can put the other node in "read only" mode while you perform a cold backup on the other node? Haven't tried, but just a suggestion. Is there a particular reason you want to make a backup of cold? RMAN works very well.

• How do I know if the RAC database or single instance?

  Hello
  
  How can you find only if the database is the only database instance or RAC? is there any table, view or setting in the settings file that you cannot know CARS?

• Unable to see the changes in the file for the RAC database alert log

  Hello
  
  We have two node cluster database. I stop a node instance with srvctl utility and then start it. When I checked the alert of this instance log, I've not seen these changes to the connected instance change log of this instance file. Ive tried with instance of shipment and found same. Why is happening. Why Oracle database is not to connect the start event and stop in the log file alert.
  
  Kind regards
  
  Abgrall

  What is your version of DB?

  If you are using 11g, use adrci > display alerts > choose the database to view the log of alerts. The events are always recorded in the alert.log, you are probably looking to wrong/old file.

• IF database-> RAC database: estimate of the size of the SGA for each instance

  Hello!

  Let's say that there is a single instance with SGA 100 G size DB (assume this size is optimal for this database).

  If this database is intended to be converted to a RAC database with 2 instances (suppose DB workload will be spread over multiple instances).

  How to estimate the needs of SGA size for each instance in the RAC database?

  It takes 50G + General cool CARS (say 15%) for each instance?

  (Do not consider situation when one of the instances has failed, and all the charge redirects to an instance having survived)

  I'd be grateful if someone has offered or provided useful references.

  ---

  Kind regards

  Kyrylo

  As a general rule, I would size the SGA on new nodes to 120% of the SGA to single instance. Yes, this means that you will more than double the size of the SGA. You will need additional space to hold the load memory Cache Fusion. And the buffer Cache are possibly a little more space to store additional versions of blocks that seem to accompany the many implementations of CARS. Now, it's just a rule of thumb, so it has a high degree to be very wrong.

  You'll want to consider two big things... (1) the service being used. Will you take advantage of the services to perform the partitioning application? If so, instances can see various workloads that can lead to requests for different resources. (2) you will support a kind of failover (TAF or manual failover) applications? If so, then the LMS must be sufficiently sized to support the additional workload.

  See you soon,.

• Multiple RAC databases on IM even using different subnets for Public i / face

  Hello. We are setting up a 2 cluster nodes. This group will be the host of several RAC databases. For security reasons, our network team want to create separate subnets for the application traffic to each RAC specific database on the cluster.
  
  For example, request 1 to 2 application servers that will connects to database PROD1 RAC via a single subnet, application 2-3 application servers etc which will be connected to the database RAC PROD2 via a different subnet,.
  
  In addition, the network team want to configure a subnet separate management DBA etc. will use to administer all the RAC databases and infrastructure in the cluster.
  
  Version 11.2.0.2 grid infrastructure. The database versions vary from 10.2.0.x to 11.2.0.2. All databases will use RAC.
  
  We want to take advantage of the features of earphone SCAN to support connectivity to databases on the cluster. 2199620 [https://cn.forums.oracle.com/forums/thread.jspa?threadID=2199620] thread suggests that 11 GR 2 supports several subnets, that seems to be exactly the functionality we need. Please can you confirm how it works and tell us any documentation (standard docs, whitepapers, MOS, etc.) which could help us to configure it.
  
  Document referenced in thread 2199620 was not exactly what we were looking for and didn't translate too well in Google Translate.
  
  Any guidance is appreciated. Thanks, Rich.

  Hello

  With Oracle 11.2, you can have multiple public networks accessing your Oracle RAC.
  You must set the init.ora new LISTENER_NETWORKS setting so users are load-balanced on their network. Services are related to the networks so users who connect with network 1 will use a different service as network 2. Each network will have its own VIP.

  Impossible to use both network SCAN function because SCAN will work into a single network and on GRID 11.2 you cannot config more than a SCAN.

  So, you can have a public network (for example, 10.10.10.0) with SCAN/VIP and another public network (e.g. 192.168.217.0) you will only use VIP on TNSNAMES.ora.

  You configure a Service (A) on the network (10.10.10.0) and one other Service (B) on the network (192.168.217.0).

  In the example above using (A) Service you will configure SCAN (scan host) and using Service (B), you must configure all address VIP.

  Kind regards

  She is entered for the RAC database, and you use the vip host name entries.

  Are you able to ping machine vipserver003 you?

  Can put you vipserver003, vipserver004 entries in your hosts file.

• How to let axSequenceView view the sequence file, after the opening before the race.

  

  How to let axSequenceView view the sequence file, after the opening before the race.

  I would do it differently, you do not see when running because your sequence control is connected to the requeteexecution Manager. I have two controls of the same size that sits on top of the other, one connected to requeteexecution as it is by default and the other to SequenceFileView Manager.

  You can then use reminders to start execution and execution of end events in the user interface to make the control visible. It is very easy to achieve.
