Log_archive_dest_2 DataGuard

Hi all

9i

RHEL5

In the dataguard configuration init.ora parameter, which is the best between the two? In terms of performance?

LOG_ARCHIVE_DEST_2 = "SERVICE = STBY LGWR ASYNC NOAFFIRM'"

or

LOG_ARCHIVE_DEST_2 = "SERVICE = STBY LGWR SYNC STATE '"


Thank you very much

JC


Hello, if your storage pending system is not the best of all or your /bandwidth of network latency is not very good, then choose ASYNC (and 9i, you can choose ARCH ASYNC... for a primary performance).

my personal experience:

300 km of primary education in the various networks... before I used ASYNC.

Primary and standby on the same data center with a low cost for standby disk storage: I used ASYNC.

Primary and standby on the same network (with good latency and bandwidth) and the upper disc AND VERY CRITICAL of DATABASE storage!, so I use SYNC.

With SYNCHRONIZATION option, all of the problems in writing to the backup site are in the PRIMARY.

Kind regards.

  • DataGuard problems, bad to the log_archive_dest_2 port configuration

    Hello! Thank you all in advance for your help and sorry for my English, I will try to explain as best as possible.

    We have a dataguard.

    It has two headphones, the ports are 1534 and 1544, but... someone changed their 1535 once there is and now I had to re-set up everything again.

    The thing is log_archive_dest_2 at the elementary level is wrong, because it points to instead of 1534-1535. I tried to edit init.ora and restart the instance but it always points to 1535 again.

    I don't know if this setting depends on the other, or there is a hidden configuration, I don't see

    I have recreated the password file in the primary and copy it to the secondary, after that I restarted both cases, but nothing

    No sense to me. Do you have a rebuild on my system and was not able to reproduce.

    At this point, I would like to grep for the problem (change of wider path if necessary)

    grep 1535 -R /opt/oracle/*

    I hate when it makes no sense. There must be somewhere.

    Subsequently

    I was thinking about it more. If you have a data broker, they can change the database settings. Any change of this?

    I see this in your settings file that supports this theory

    *.dg_broker_start=TRUE

    Any set of values in Data Guard Broker wins the spfile parameter. So no matter what you the SPFILE and PFILE broker file overwrites.

    Or modify the 'StaticConnectIdentifier' proposal the data broker. See doc Oracle E17023-04

    "6 scenarios using the DGMGRL command-line Interface"

    What you have shown here is the log_archive_dest_2 of the primary database. You must clear the log_archive_dest_2 of the standby database too.

    The error is speaking on the parameter log_archive_dest_2 of the database pending. 12 c, then the broker configuration, you must clear the log_archive_dest_2 (destinations archive remote) on the primary and standby databases. DG broker would take care of her.

    On autonomy in standby:

    SQL > alter system set log_archive_dest_2 = ";

    And then try to add the standby database to the broker configuration.

  • RAC RAC, DataGuard

    Hi all

    I want to have dataguard with cars at two knots in physical configuration and standby.

    For this I have question how archives will be transmillted from the primary to physics.

    This means that the head node 1 will on node1 Eve and similarly for node 2 archives or all primary archives will be forwarded to node 1.

    Kind regards.

    It is understood that if any node on sby descends to archive two primary nodes will keep to be shipped on an active node of SBY (only MRP should be active on THST)... good?

    Yes, if MRP is not running on the active node of the standby, then you must manually start the MRP.

    If she is correct understanding, then I have only one doubt that we all configuration setting or a parameter for this archives begin is transmitting on the active node on SBY or oracle manages automatically?

    No, you don't have to make any changes.

    Reason: on the database principal, you set the log_archive_dest_2 (or any remote dest parameter to ship again to wait), you would use the "service ='.»»

    This alias would have the "scan name" Eve and all the nodes of the standby registered the listener to scan that you can be aware of. So even if 1 the standby node goes down, primary will always be able to ship the remake on the eve and the node is active on the eve will receive them and apply.

    For example:

    On the primary:

    The log_archive_dest_2 looks like:

    Service string LOG_ARCHIVE_DEST_2 = "srpstb", ASYNC NOAFFI

    Optional delay of RM = 0 compressio

    n = disable max_failure = 0 max_co

    nnections = 1 reopen = 300 db_uniq

    ue_name = "srpstb" net_timeout = 3

    valid_for 0, =(online_logfile,a)

    ll_roles)

    NET watch alias name looks like this:

    SRPSTB =

    (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP) (HOST = ora12cdr-scan)(PORT = 1521))

    (CONNECT_DATA =

    (SERVER = DEDICATED)

    (SERVICE_NAME = srpstb)

    )

  • Doubt on the performance mode maximum dataguard

    HI gurus,

    We have a dataguard environment configured in 12.1.0.2.0 on 5.6 OEL. DataGuard is configured in maximum performance using following congiguration,

    18:26:26 SQL > show parameter log_archive_dest_2

    VALUE OF TYPE NAME

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

    string LOG_ARCHIVE_DEST_2 = TGOID NOAFFIRM LGWR ASYNC COMPRESSION service = ENABLE VALID_FOR =(ALL_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = TGOID

    Here I used LGWR ASYNC and enabled real-time apply to my waiting to help,

    SQl > alter recover managed standby database disconnect log file using current;

    Here are my doubts,

    1. If we allow real time apply, the changes will reflect on the eve when a commit happens in elementary school. is this correct?

    But here I do not see this behavior, changes are get applied to the previous day only when I do a log switch. (as in the case of the mode of transport ARCH)

    2. so, if I want to get changes made to the previous day when a commit happens at the elementary level, is I need to set the following?

    First of all,

    ALTER system set log_archive_dest_2 = service = TGOID ASSERT LGWR SYNC COMPRESSION = ENABLE VALID_FOR = (ALL_LOGFILES, PRIMARY_ROLE) DB_UNIQUE_NAME = TGOID scope = both;

    Secondly,.

    ALTER DATABASE BASE_DE_DONNEES SLEEP TOGETHER IN ORDER TO MAXIMIZE THE AVAILABILITY/MAXIMIZE PROTECTION.

    is this correct?

    3 if its OK what is the advantage of using lgwr async in maximum performance? then, what is meant by real time applies to maximum performance?

    Thank you and best regards,

    Mahi

    If you want the data validated to be simultaneous on two sites, use maximum availability (or maximum Protection).  The 'risk' with maximum Protection, it is that if the network link fails or breaks down the day before or the day before is not able to write it again received, the primary has put an end.  The 'advantage' (but also the 'risk' If you keep monitoring it) with maximum availability is the primary can return to maximum Performance If the night before does more (for any of the reasons stated in the first sentence)

    Allow standby redo logs Oracle to write again to the backup site without waiting that the primary archive the Redo Log.  If your primary online Redo log is archived every 30 minutes and you only run on base ARCH, you may lose 30 minutes of transactions.

    However, when configuring physical Standby I read:

    This destination transmits redo data to the remote physical expectations

    Can someone give me a hand

    Christian

    Log_archive_dest_n manual management (and other DG Associates init parameters) and using Data Guard Broker to manage automatically these settings is not the right way (it may cause inconsistency between the spfile and broker configuration files).
    You must clear the log_archive_dest_n parameters defined with the attribute of SERVICE and without NOREGISTER attribute, and then try to create the broker configuration (it will automatically set the log_archive_dest_n when you add a database to the configuration).

    When you use data guard broker always make your changes through DGMGRL for consistency purposes.

    Kind regards

    No, none of your options are suitable.

    If you have ARCH, then you don't need real-time applies. Option B ARCH transport if you are waiting for newspapers to be switched, archived and shipped. Unless you set archive_lag_target you have no real guarantee speed will be.

  • Configuring RMAN for dataguard.

    Hi all

    Here we have an environment dataguard with db1 (db_unique_name) as primary and db2 (db_unique_name) Physics of the standby database. For primary and secondary the ORACLE_SID is "oracledb." We have configured dataguard in environments of 10 g and we don't use a grid control. And now we want to configure rman for incremental backups. We use a third database of catalog which we recorded primary DB successfully. When the primary configuration of rman is show conflicts. Even changes to the main configuration of RMAN are applied on the standby too who I think shouldn't happen in this scenario. How to solve this problem? Is what is happening because of the ORACLE_SID even for primary and secondary school? I enclose the link from the doc, we also followed the errors and configuring in rman. Can anyone help?

    If you see your date system current and last does the end is not even a second. So probably there is no delay I would say.
    You can test by setting the timeout setting in log_archive_dest_2 (or) disable log_archive_Dest_2 for a while do two or three switches of newspaper and made attention to discrepancies between primary & eve and how does it point of view.

  • Upgrade Dataguard 9.2.0.8 (32-bit) to 10.1.0.5(64-Bit)

    What is the best way to do this with minimal downtime. I have two (2) machines [the two 32-Bit] primary (9.2.0.8) and Eve (9.2.0.8)... I need to switch the primary and standby to 10.1.0.5 (64-bit) to new hardware, limited service disruption. I'll have the new machines built and installed with 64 - Bit. My question is: can I have a computer 32-bit archlogs sending to a 64-Bit machine to apply (Dataguard)? My thought was to have the original upgraded to 10.1.0.5 (32-bit) 32-bit machine (9.2.0.8) Firstly build a Dataguard on one of the new 64-Bit machines and ship the new machine until the changeover weekend newspapers. I read a few posts that I can have a 32-bit database running on a 64-bit computer (with just the RPM 64 - Bit and 64-Bit o/s installed), deliver the newspapers to the Machine 64 - Bit, and then failover weekend change the wordsize of 32 bit to 64 bit, but don't know how true that is. Any help would be greatly appreciated

    I agree with FZheng, you should consider Oracle 11.

    You can avoid a database bounce by putting in place all your new settings Data Guard and FRA beforehand. And you can use an alter system to change the LOG_ARCHIVE_DEST_STATE_2 of "reporter" while you use RMAN duplicate to create the day before.

    So to build the new system, but add these settings even before starting the data move from Oracle 9.

    FAL_SERVER
FAL_CLIENT
STANDBY_FILE_MANAGEMENT=AUTO
DB_UNIQUE_NAME
DB_FILE_NAME_CONVERT
LOG_FILE_NAME_CONVERT
log_archive_dest_1
log_archive_dest_2
LOG_ARCHIVE_DEST_STATE_1
LOG_ARCHIVE_DEST_STATE_2
LOG_ARCHIVE_MAX_PROCESSES

    Create your spfile on the primary with LOG_ARCHIVE_DEST_STATE_2 set to ACTIVATE and you avoid a stop and restart later. Then change to DELAY until you build the day before. You can save time more by copying the password in advance. Wait to issue the FORCE LOGGING until all the data is transferred.

    Place your tnsnames and the Auditor including _DGMGRL on both servers in advance.

    If plan you correctly, you can use RMAN two copies and never primary stop. The day before will just begin to apply again them.

    If you find this "Helpful" Please mark as well.

  • Choose the mode of protection of active dataguard

    Hi gurus,

    I'm confused with dataguard Active Setup mode - what do I have to configure physical shall make use of an actress dataguard. I know that I can even use ensures maximum performance with redolog for real-time query. But what is the minimum protection mode to run active dataguard.

    How can I configure a delay of 1 hour for active dataguard in GR 11, 2?

    Thank you

    You said:
    >
    By default, Dataguard is in maximum performance mode... We can define the time of one hour by setting the
    LOG_ARCHIVE_DEST_2 = 'service = to_standby lgwr async affirm reopen = 60'
    or
    LOG_ARCHIVE_DEST_2 = 'service = to_standby lgwr async delay = 60'
    >

    I'm sorry, but your first log_archive_dest_2 value is not correct:
    The combination of ASYNC & AFFIRM is not taken in charge and not sensitive; REOPEN = 60 will not delay applying it again

    See here for a good explanation of log_archive_dest_n:

  • R12 with dataguard

    Salvation;

    I need advice on an issue.

    I have 2 instance working on VMware and am available for r12.0.4 on RHEL4 dataguard in following:
    Continuity of Oracle Applications Release 12 on exit 10 gr 2 - Single Instance database and RAC [ID 452056.1]

    The two server has the same SID,
    different db_unique_name,
    Users and the EBS installation path are same
    valid information IP and hostname in/etc/hosts
    tnsping knit both primary and standby

    The problem is archiving log doesn't send primary eve. DB primary while I run
    SQL > alter system archive log current;

    I have this in the error log:

    I checked LOG_ARCHIVE_DEST_2 and good sound.
    I can use TNSPING wihtout problem (using "" < nom_du_contexte >ifile.ora ' under the $TNSdirectory ADMIN ")

    Server mutually can ping with the IP address or host name.

    Any who face a similar question before?

    Helios,

    What is the value of the parameter 'log_archive_dest_state_2 '?

    Thank you
