What effect does resizing temp file on primary have on standby database?

We have a weekly job on Primary that resizes the temp tablespace.
STANDBY_FILE_MANAGEMENT='AUTO' so am I correct in the assumption that the changes will be passed on and replicated on standby, even though they are temp files?
I am going live with DG in 2 weeks and keep thinking about questions such as this!
Thanks

Writes to tempfiles aren't logged, so aren't shipped to the standby database. Writes to the tempfile on the primary causing the tempfile to extend won't cause the tempfile on the standby to extend. Tempfiles on the standby can be added/dropped/resized independently to the primary, even with STANDBY_FILE_MANAGEMENT='AUTO'.
If the standby is purely for disaster recovery and left permanently in managed recovery mode, then the standby won't even need a tempfile until after it has been activated in a failover/switchover situation.

  • What effect does closed credit card accounts w/ a balance I'm paying off have on my credit score.

    I've closed three credit card accounts and I'm paying off the balance on them What effect does that have on my credit score?

    Don't think it will take a hit right now. It stays on your report for 10 years after you close it. Even though you pay it off, removing the cards will raise your available credit, leading to a higher UTIL %. But UTIL % is overrated. Long as its below 30%, should be fine.

  • Redo log files are not applying to standby database

    Hi everyone!!
    I have created standby database on same server ( windows XP) and using oracle 11g . I want to synchronize my standby database with primary database . So I tried to apply redo logs from primary to standby database as follow .
    My standby database is open and Primary database is not started (instance not started) because only one database can run in Exclusive Mode as DB_NAME is same for both database.  I run the following command on the standby database.
                SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
    It returns "Database altered" . But when I checked the last archive log on primary database, its sequence is 189 while on standby database it is 177. That mean archived redo logs are not applied on standby database.
    The tnsnames.ora file contains entry for both service primary & standby database and same service has been used to transmit and receive redo logs.
    1. How to resolve this issue ?
    2.Is it compulsory to have Primary database open ?
    3. I have created standby  control file by using  command
              SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS ‘D:\APP\ORACLE\ORADATA\TESTCAT\CONTROLFILE\CONTROL_STAND1.CTL‘;
    So database name in the standby control file is same as primary database name (PRIM). And hence init.ora file of standby database also contains DB_NAME = 'PRIM' parameter. I can't change it because it returns error of mismatch database name on startup. Should  I have different database name for both or existing one is correct ?
    Can anybody help me to come out from this stuck ?
    Thanks & Regards
    Tushar Lapani

    Thank you Girish. It solved  my redo apply problem. I set log_archive_dest parameter again and then I checked archive redo log sequence number. It was same for both primary and standby database. But still table on standby database is not being refresh.
    I did following scenario.
    1.  Inserted 200000 rows in emp table of Scott user on Primary database and commit changes.
    2. Then I synchronized standby database by using Alter database command. And I also verify that archive log sequence number is same for both database. It mean archived logs from primary database has been applied to standby database.
    3. But when I count number of rows in emp table of scott user on standby database, it returns only 14 rows even of redo log has been applied.
    So my question is why changes made to primary database is not reflected on standby database although redo logs has been applied ?
    Thanks

  • What effect does velocity have on sound?

    im fairly new to java sound, and i was playing around with channels and notes, i made myself a nice little program that plays 1-16 notes at the same time on the 1-16 channels of an midi synthesizer.... anyways, all the notes are set randomly, but the velocity stays constant? would i notice any difference (between the same note) if i changed the velocity? what effects if any does the velocity have?

    Velocity is how hard the key was struck. It can have all sorts of effects on the sound, but mostly it affects the volume.

  • Primary and Physical Standby databases hanging on sqlplus shell command...

    I am primarily a java developer that has had the task of oracle dba thrust upon me due to circumstances that are beyond my control. In the QA lab we have two oracle 10 g release 1 instances running. They set up in a dataguard configuration: one is the primary and the other is in a physical standby.
    Last week I noticed that the disk space on the primary database was at 100%. After some investigation I discovered that a good deal of the files taking up space on the box were log files and the best solution that I could think of would be to delete all old archive files. So I deleted the old archive files that were at least two weeks old using RMAN.
    During this week the database started to shutdown automatically. The QA associate restarted the database twice using the ‘STARTUP’ command from sqlplus. Additionally, the standby database began to have issues: when login in to sqlplus the application would just hang: no ‘SQL” prompt or anything. Finally today the primary database has also begun to hang in a similar manner.
    I have looked at many of the trace files and alert logs but haven’t been able to really discern what the real problem is with the database and the proper rectification for the database. Does anyone have a clue into what is going on? If someone could even point me in the right direction it would be greatly appreciated.

    Guessing that your flash recovery area is full, archiving is stopped so the instance appears to hang.
    Do you see messages like so in the alert log:
    You have following choices to free up space from flash recovery area:
    1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
       then consider changing RMAN ARCHIVELOG DELETION POLICY.
    2. Back up files to tertiary device such as tape using RMAN
       BACKUP RECOVERY AREA command.
    3. Add disk space and increase db_recovery_file_dest_size parameter to
       reflect the new space.
    4. Delete unnecessary files using RMAN DELETE command. If an operating
       system command was used to delete files, then use RMAN CROSSCHECK and
       DELETE EXPIRED commands.

  • Diagnosing an ASM space issue for a primary and a standby database instance with external redundancy.

    I've received an alert from Enterprise manager saying "Disk Group DATA_SID requires rebalance because at least one disk
    is low on space". My colleague who I would go to with this question is unavailable, so this is a learning opportunity
    for me. So far google and Oracle documentation have provided lots of information, but nothing that answers my questions.
    I've run the following query on both the primary and standby databases ASM instances:
    select name, disk_number, sector_size,os_mb, total_mb, free_mb, redundancy from v$asm_disk;
    On the primary I get 4810M Free space and 18431M Total Space
    on the standby I get 1248M Free space and 18431M Total Space -- this is the one that complained via OEM
    When I run the following query in the database instance:
    select sum(bytes)/1024/1024 MB from dba_segments;
    I get 3736.75M as a result.
    My questions are:
    1. Will OEM's suggestion to rebalance the disk actually help in this situation since the instance is set up with external redundancy?
    2. If I've got 18G of space and only 3.7G of data, why is OEM complaining?
    3. How can I reclaim what I presume is allocated but unused space in my problem disk group?
    4. How can I determine what extra data the standby has that the primary doesn't since both have the same total space allocation, but different amounts of free space?

    Thank you for the reply. That link is very good.
    We are an 11.1 version of our database. Linus is OEL 5.6.
    So, looking at the portion of the link that refers to 'Add Standby database and Instances to the OCR' - If we use SRVCTL to give the STANDBY the role of ‘physical_standby’ and the start option of ‘mount’, what effect will that have if the STANDBY becomes our PRIMARY?
    Would these database settings need to be modified manually with SRVCTL each time?
    We understand why the instance is not starting when the node is rebooted, we are looking for a best practice of how this is implemented.
    Thank you.

  • What effect does Audit logging have on system performance?

    Hi
    I'm aware that the question might not be easy to answer, but is there any rule of thumb or any way to calculate what the enabling of the Security audit filtered on all users in all clients would have on the performance of the system?
    We are trying to get all of our business to use the same audit logging settings, but we need to be able to show how performance might be affected by this change.
    Thanks
    Tomas

    Hi Thomas,
    that is not hard to tell, but impossible to tell....
    Please refer to SAP note #429343 .
    Suggestion: switch on the log on one of your servers (dynamic switch) and trace the
    impact during normal daily business.
    You will have then a basis for your decision.
    If you activate it then generally, consider that every server should write into its own (local) directory to avoid big performance issues (network, file system).

  • What effect does recording at 24 bit..44.1 have when bouncing to 16-bit CD

    Hi,
    Before I really start recording on Logic, I'd like to know if someone could clear this up for me.
    I know CD quality is 16 bit 44.1. So if I know I am going to distribute my recordings onto CD in the end, why should I record at 24-bit?
    and if i do record at a higher resolution than CD quality, and I mix the recording as hot as I can w/o distortion, what will happen to my quality when I mix to cd??

    Re: Sample rates - 48k. Wow, that goes against everything I've read in years about the greater potential for aliasing artefacts in "non-multiple" SR conversion. Esp. software.
    It depends on the software you are using for the
    conversion. Many of the DAW's do a less than
    steller job at this, Logic being one of the worst
    at the moment. ( I have a feeling that the new
    version of Logic will address this problem). As
    it turns out Adobe and Bias make software
    that does an excellent job at sample rate conversion
    with no alaising artifacts. Adobe's software
    is not available for the Mac and Bias's Peak Pro
    is on the expensive side.
