Clusterware :: How Much Space Should Apply For ASM Instance
Aug 6, 2012
I will begin to install Oracle Clusterware (11gR2), but I need to know how much space should I apply for the ASM instance? What size should I apply the shared disk to the nodes?
I have to apply monitoring template on my databases. Databases are already added and configured into OEM. They are visible under Databases tab and also under Groups where I have added them.
But when I try applying monitoring template and look for database in search window, it doesn't appear there.
i am configuring asm on clusterware when i create instance on node1 and node 2 a message screen appear " Cant start asm instance on node 2)When i start asm instance manually on node 2 i found the below error in alert log file.
ORA-27508 IPC error sending a message ORA-27300 OS system dependent operation:send msg failed with status: 101 ORA-27301 OS failure message: Network is unreachable ORA-27302 failure occurred at: sskgxpsnd1
I guessed that was because of LUN size (it was exceed 2 TB)After that I dinamically shrinked LUN size on our external storage, rebooted and perfomed cfgmgr command on both nodes. But I still have no enough free space.
I am configuring Grid Infrastructure 11g2 on node A, one of two cluster nodes, and getting the following message: [INS-40916] Single-instance versions of Cluster Synchronization Services (CSS) are detected.
I executed runInstaller and installed software-only on both A and B nodes. It apparently the other node has already CSS instance running, and maybe caused by the installation.I remove the software from A first?
How do I stop CSS on the node A, and let the configuratoin to continue on this node B
i have installed grid(crs+asm) on my two linux node(Enterprise linux 5) setup, using openfiler(SAN) , i have configure grid Home like ORACLE_ HOME=/ u01/ home/app/11.2.0/grid.
1) i don't get any instance specific asm parameter file like init+ASM1.ora instead of that i got ab_+ASM1.dat, hc_+ASM1.dat, init.ora, orapw+ASM four files, do i need to create ASM instance specific parameter manually to create diskgroup in the same location,
2) +DATA diskgroup has been created while grid installation, but when i try to create database, its giving me error diskgroup +DATA doesn't exit or not mount, but when i check it shows me mount like below $cd $ORACLE_HOME/dbs (here oracle home is grid home)$export ORACLE_SID=+ASM1$sqlplus / as sysdba>select name,state from v$asm_diskgroup; name state DATA Mounted even i cant able to dismount diskgroup DATA, it throws an error insufficient privilege.
3) After grid installation how can one create diskgroup i mean what needs to exported as ORACLE_SID like in 10g we have $export ORACLE_SID=+ASM1 then creat diskgroup.
I would like to use Oracle Grid Infrastructure to protect a single-instance database.
I found these docs:

I was unable to find a similar document for GI 11.2 . Do you know if such a document exists?
At the moment I only know that the GI is free if used for an Oracle Product, but I am not shure whether it can be used to protext external applications or single-instance databases
I am trying to design a database consolidation high-availability cluster for Oracle 11g R2 64-bit Enterprise Edition (X86-64) on Oracle Linux 6.x UEK, using Oracle 11.2.0.3 (the latest as of Aug 2012).
We don't need RAC Multi-Node now or in foreseeable future because none of the databases we run break the capacity of a single node. Likewise, we don't need to use Oracle VM to virtualise the database instances.
We plan to use SGA and PGA memory management to run multiple instances on same hardware operating on a single Linux 64-bit O/S image.Does it sound ok so far?
Two or three of 4-socket, 40-core Intel 64-bit servers with 512GB of RAM each (relatively cheap at today's HW commodity prices) will be sufficient to run all Oracle databases we have on Linux 64-bit.So the two HA options that I know of are:
(1) use Oracle Clusterware/Grid/ASM to provide for instance failover (2) use Oracle RAC One Node on top of Clusterware/Grid/ASM
As I understand it RAC One Node is significantly more expensive than the "free" Oracle Clusterware/ASM/Grid (since we own Oracle 11.2.0.3 Enterprise Licences already). So why should my employer pay for RAC One Node licence given they already own Single Instance Fail-Over and Restart protection from Clusterware/Grid/ASM ?
I also read that Data Guard 11.2 may not be supported with RAC One Node on 11.2? True? Will same Data Guard 11.2 work with a Single-Instance Failover running on Clusterware/Grid/ASM ?
-Who is running RAC One Node? Why? -Who is running Single Instance Failover with Clusterware? Why? -Who is using Data Guard with either of the above?
- one ASM instance - X DB instances - each DB instance uses 2 or more dedicated diskgroups from the ASM instance - there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view - the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?
Sysaux Tablespace is running low. WE SET AWR RETENTION TIME=60 DAYS. WE ARE NOT INTEREST TO EXTEND SYSAUX TABLESPACE SIZE. Usually we take AWR weekly once. Some times we did ADDM report and ASH.
CODEsql>select TABLESPACE_NAME, FILE_NAME, BYTES/(1024*1024), AUTOEXTENSIBLE, MAXBYTES/(1024*1024) from dba_data_files where tablespace_name = 'SYSAUX';
1. What's the best SOLUTION ? 2. Can i shrink sysaux tablespace ? 3. I think , The size for all occupants in sysaux tablespace is less than 200 MB => how to find actual content of sysaux tablespace ? 4. What could be the reason for growth? Is there any way to free the space from sysaux table space?
Does we need to apply the patches in sequence. i installed oracle 11g r2 today only, then which patch i can install. if i like to install CPU, then does i need to install all the previous or only the latest one. if only latest one only, then how can i find the CPU patch number.
of course, instead of cpu i can install psu patch, then which one has to install. only latest one or all previous also. if latest one only how to find latest psu patch that has to apply.
I need to migrate a 500 GB 10.2 database from windows to linux. Of course I found Alejandro Vargas paper on how to do that ("Database Migration From Windows to Linux Using RMAN"). My problem is that the source database will be up again for 7 days and I need to apply all changes made to the source database to the migrated linux database.
Can I just take all redo log files generated from the source database and apply those to the destination database? I might have a problem with a) file conversion and that the redo log are not in sync with the target database (different check points?).I just found that on an exotic website: "The contents of a redo log file depend on a combination of Oracle version, operating system and server architecture. In general redo logs written on one architecture cannot be read on another. There are a few exceptions to this rule. For example, in Oracle 10.2 a redo log written in Linux can be read by a Windows database."
So if this is true, does it also work the other way AND will the database migration from window to linux create a perfect clone of the database where those redo log files actually can be applied to?
We need to apply the the 11.2.0.2 database server patch and this is a 12i Ebusiness suite env. Do we need to take any precautions(other than stopping the apps) on the APPS side when we are applying the patch on the database?
I have created Replication process for a single table using the below mentioned script.
connect sys/afccv@afccv as sysdba show parameter open_cursor create user STRMADMIN identified by STRMADMIN; ALTER USER STRMADMIN DEFAULT TABLESPACE USERS TEMPORARY TABLESPACE TEMP QUOTA UNLIMITED ON USERS; GRANT CONNECT, RESOURCE, AQ_ADMINISTRATOR_ROLE,DBA to STRMADMIN; execute DBMS_STREAMS_AUTH.GRANT_ADMIN_PRIVILEGE('STRMADMIN'); connect sys/vxmldb@vxmldb as sysdba
[code]....
According to Alert log file Replication process started( Refer Alert log content below

Now When I am checking the apply status then it is showing Dequeue message
SQL> l 1* select apply_name,state,DEQUEUE_TIME from V$STREAMS_APPLY_READER SQL> / APPLY_NAME STATE DEQUEUE_TIME ------------------------------ ----------------- -------------------- STRMADMIN_APPLY DEQUEUE MESSAGES
when I am checking the number of rows on both tables (source and destination) , at destination it is not applying any thing.
How To Apply Group by Command in Forms 6i at block level for example in data block a field name is code,quantity and code replicate many times it is not working with out commit but i want to calculate sum of quantity in data block by code group before commit
if we apply this command at sql level then command is
select code,sum(nvl(quantity,0)) from sal_detail group by code and its work very well
CODEhost22 (Oracle Linux 5.9) | host30 (Windows XP) with SQL Server Express 2008 DB22 | Gateway to MSSQL | DB30 Local Local | | Capture --> Apply ------> Gateway -----------------> DUMMYUSR.DUMMYTBL Process Process | |
Capture process on DB22 captures changes made to local DUMMYUSR.DUMMYTBL table, enqueues it to capture queue and propagates to apply queue for local apply process, which, using database link DB30 supposed to apply these changes to table DUMMYUSR.DUMMYTBL on remote SQL Server database DB30.
The problem is that when apply process is executing transaction, it aborts with error: QUOTE ORA-26713: remote object does not exists or is inaccessible. ORA-26712: remote object is "DUMMYUSR"."DUMMYTBL"@"DB30". In trace log I can see the following message: QUOTE kniNoPrimaryKeyError: ORA-26713, remote obj doesn't exist, DUMMYUSR.DUMMYTBL@DB30 [code]...
what can cause ORA-26713 error of apply process applying changes to SQL Server database through Oracle Database Gateway, if object to be modifyed exists and accessible from Oracle database for strmadmin user?
By the way, database link and tables were created with following commands: CODEDB22(Oracle): (connected as strmadmin) create database link DB30 connect to "dummyusr" identified by "dummypwd" using 'DB30';
DB22(Oracle): (connected as dummyusr) create table DUMMYTBL (no number, name char(6), ddate date, payload varchar2(2013)); DB30(MSSQL): (connected as dummyusr) create schema DUMMYUSR authorization dummyusr; create table DUMMYUSR.DUMMYTBL (no float(53), name char(6), ddate datetime2(0), payload varchar(2013));
i have attended an interview there i got a question like--->There are 100 archives generated in standby in that a series of five archives are missing and those are not available in the primary then how will you do.....
can we apply 11.1.0.7 Patch Set on a 10.2.0.3 database server? i mean are patch sets cumulative or do i have to install the patch specific to my release the issue is i have the below error with rman: RMAN-03009: failure of delete command on ORA_DISK_1 channel at ORA-19633: control file record is out of sync with recovery catalog
I want to apply divide and conquer approach on the field value, For example I have the field value like this
Value 32,36,12,65,85,9663 43,36,89,65,112,9663 36,63,12,65,95,123 32,36,12,85, 85,9663
Remember that these value are taken from ONLY one field i.e Value. Apply the divide and conquer approach in such a manner that take the value of a single field and each row and divide the value into two half. Continue this process until single value until we reach the single value or single sub problems.
Apply the divide and conquer approach on all the value of field. When we get final value then match the value of two different rows. And check how much field value are similar (match or duplicated). If field values are match more then 80% then delete the duplicated value and keep the original entity.
CREATE TABLE prod_vendor_record ( vendor_record_seq_no NUMBER NOT NULL, study_seq_no NUMBER NOT NULL, vendor_subject_seq_no NUMBER NULL, control_dataset_seq_no NUMBER NOT NULL, checksum NUMBER NOT NULL, processing_flag VARCHAR2(1) NULL,
[code]....
and executing below query on those tables-
insert into prod_temp_vendor(vendor_record_seq_no,checksum,rownumber,transaction_type,iu_flag) select vr.vendor_record_seq_no, tvr.checksum, tvr.rownumber, tvr.transaction_type, 'U' from prod_vendor_record vr, prod_temp_vendor_record_20000 tvr where vr.study_seq_no=25707 and vr.control_dataset_seq_no=3910 and vr.key_hash=tvr.key_hash and dbms_lob.compare(vr.key_col_val, tvr.key_col_val) = 0 and tvr.error_flag is null;
let me know on which columns of PROD_VENDOR_RECORD table to apply index to make processing faster. As I tried to build index like below-
CREATE INDEX idx_prod_vendor_record ON prod_vendor_record ( study_seq_no, control_dataset_seq_no, key_hash ) /
But it is not being used by above query (see execution plan)
I have a primary database orcl and logical standby database orcl_std.
Real time apply is enabled. I have standby redologs in both primary and standby sides and I`ve started recovery with below command:
ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
When I create a new table in primary database, I am unable to see it on standby database (Although real time apply is enabled) However, when I switch log in primary, I can see the new table in standby database.
My question is, why realtime apply is not working in my scenerio ? I was expecting to see the new table immediately in standby database once it is created in primary database. Why am I supposed to wait for log switch in real time apply ?
,I am trying to set up Streams on a 11.2.0.3 on a Windows 2008R2 server. Due to an error in running propagation, i a, trying to delete both Capture and Apply queues. I have deleted the Apply queues but unable to drop the Catpure,

Can I apply Referential Integrity to only selected rows of a particular column? This is the reference key to the primary key to another table. But, the issue is, this reference column is not having mandatory data for all the rows. So, whenever this is null, I dont want it to be referred by parent table.
no, and it makes no sense to do so either
We have an appointment form in our HIS, where patients take telephonic appointment. That time they may not know their user id given by hospital. So, it remains blank & name is entered manually. But if the user-id is entered, it must fetch patient name from the master.
The candidate key must be unique within its domain.The candidate key can not hold NULL values.
MRREGISTRTNHD is a patient master & has a primary key named N_PATIENTMR_ID. HLTHCHKAPPOINTHD is a appointment table & has a foreign key named N_PATIENTMR_ID which references N_PATIENTMR_ID of MRREGISTRTNHD.
Also, N_PATIENTMR_ID of HLTHCHKAPPOINTHD is not a unique key & it can contain null values also. I want to define constraint or any other method such that only the not null values are referenced to the master i.e. it should validate in the master. And null values should skip this reference.
Now, what happens is due to this constraint, when I'm trying to edit & update the rows having null value in N_PATIENTMR_ID, it gives the following error.
ORA-02291: Integrity constraint (SYS_C007145) violated - parent key not found
So, can I give some condition in the above constraint saying, apply this constraint to table HLTHCHKAPPOINTHD only having the not-null values in N_PATIENTMR_ID coulmn?
