Hi all,

Hello;
I have no Data Guard 9 to review. However I might try this :
select * from "_DBA_APPLY_PROGRESS";
OR
select time_mp,time_dp, scn_wrp, scn_bas, scn from smon_scn_time;Also found this: ( almost certainly NOT a physical Standby )
SELECT APPLIED_SCN, NEWEST_SCN FROM DBA_LOGSTDBY_PROGRESS;Best Regards

Hello;
Generally for the connection to work you need to add something like this to the listener.ora file :
(SID_DESC =
    (global_dbname = STANDBY.hostname)
    (ORACLE_HOME = /u01/app/oracle/product/11.2.0.2)
    (sid_name = STANDBY)
)You should stop and start the listener on the Standby after adding this. Also your tnsnames.ora must be correct on both the primary and the Standby.
Also you need an INIT for the Standby side :
STANDBY.__db_cache_size=343932928

Snapshot standby database in oracle 11g r2 RAC

Folks,
i am just wondering if the process is same for standalone and RAC snapshot standby database.
We have a DR test
1 / I just converted the standalone DR on 11g to snapshot standby database for users to do some testing and reverted back to physical standby after test was done. i folllowed metalink note ID 443720.1
2/ now there is anotherDR test where we have 2 node prod and 2 node DR on oracle 11g rel2 RAC, so not sure we can follow the same process that i used for 11g standalone database. If somebody have done this on RAC, would you please provide the steps ?
Thanks in advance

I haven't done a Snapshot Standby (RAC or non-RAC). But I see no reason why it shouldn't work with a RAC Standby either.
The command is a Database level command, not an Instance level command.

Procedure for creating logical standyby database for oracle 11g?

Hi all,
can anybody provide me docs /procedure for creating logical standby databse for oracle 11g standard edition.
Aravind

Aravind,
1. The Oracle Standard Edition does not have standby mechanism, you should do it manually or go for Enterprise Edition.
2. It's rather a question for General Database Discussions instead of Peoplesoft.
Any further question regarding that point, please post out there.
Nicolas.

Migrate peoplesoft sybase HRMS database to oracle 11g

Hi All,
I want to know if I can migrate a sybase peoplesoft HRMS database to oracle 11g using sql developer 3.0. I am trying to do this following the steps given in the link below but it is taking for ever for the convert step, I could see the messae saying building converted model.
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/sqldev/r30/SybaseMigration/SybaseMigration.htm
The sybase database is 55GB and the version is 12. There are around 20,000 tables in Sybase Database.
Please advise, if this is possible with SQL Developer??
If yes, how long this process might take(for each step in the above link), based on any past convertions of the same size database??
If this is not feasable with SQL Developer because of the complexity of the database, are there any other tools we can look into which might be faster/better than SQL Developer.
Please advise.
Thanks..

Hi Dermot, Tanks for the reply.
"Do you know the number of views and procedures captured". Below is the ouput from some of the tables in migration repositary.
count from md_derivatives table, grouped by derived_type.
MD_CATALOGS     1
MD_USERS     1
MD_CONNECTIONS     2
MD_SCHEMAS     4
MD_TRIGGERS     40
MD_VIEWS     34316
MD_TABLES     48048
MD_INDEXES     55850
MD_INDEX_DETAILS     112043
MD_COLUMNS     766244
Count from md_views table 34316
Count from md_additional_properties table 110322
"Is there a chance the convert phase has hung, or does it refresh ever so ofter with details of another object being "migrated"?"
It is not hung. I can see the message 'Translating views' right now, and the View names change often but not fast roughly every minute. When I checked for what the session is doing, I could see the below two sql statements.
SELECT PROP_KEY, VALUE, PROPERTY_ORDER, CONNECTION_ID_FK
FROM MD_ADDITIONAL_PROPERTIES
WHERE REF_ID_FK = :1
ORDER BY PROPERTY_ORDER;
SELECT ID
FROM MD_TABLES -- Some times this is MD_VIEWS
WHERE SCHEMA_ID_FK = :1 AND UPPER (TABLE_NAME) = UPPER (:2)
"What is the current "Being migrated" information?"
Translating View xxx.
"Does the tablespaces your migration repository schema is based on have sufficient space?"
Yes, Since there is no data at this point, it is all done in one table space which is set to grow UNLIMITED. At this point the size of the table space is a little over 500M.
"Is SQL Developer being run on the same machine as the Oracle database containing the migration repository? (conversion can be alot quicker for procedure,view,trigger conversion if SQL Developer is on the same machine as the repository)"
NO. SQL developer is running on my machine but the migration repositary is in the database which is on HP-UX box. Below are some of the details of the server. Also, since the database in on HP-UX, I couldn't find SQL developer for UNIX. I also read in the release note of 3.0 that it is not supported with UNIX, Is that right? else is there a way I can install SQL developer on the Unix server and that might improve the performance!, if yes, please guide me with the steps to do this installation.
Server:
Processors: 4, CPU version: PA 8700 CPU module 3.1, clock Frequency: 750MHz, Hardware Model: 900/800/L3000-7x, Kernel width Support 64.

I see the below when I do a 'glance' on the server. Looks like it is using most of the memory and the Swap. These are the numbers from the server after the migration started, they stay consistent all time with very small variation.

I need to create two databases in oracle 11g on linux.
how to set SID'S in .bash_profile and change the init.ora file.
pls anyone let me know

If you have different databases on same node you could choose to not set ORACLE_SID in shell init file but use instead interactive oraenv Oracle script to set the right ORACLE_SID.

Can i create a standby database in oracle 10g standared edition ?

what are the steps required for creating a standby database using oracle 10g standard edition. or Any other feature for mirroring database in oracle 10g standared edition

Dear mithun,
Please read the following online documentation;
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/standby.htm
+"+
+2.3.2 Oracle Software Requirements+
+The following list describes Oracle software requirements for using Data Guard:+
+* Oracle Data Guard is available only as a feature of Oracle Database Enterprise Edition. It is not available with Oracle Database Standard Edition. This means the same release of Oracle Database Enterprise Edition must be installed on the primary database and all standby databases in a Data Guard configuration.+
+Note:+
+It is possible to simulate a standby database environment with databases running Oracle Database Standard Edition. You can do this by manually transferring archived redo log files using an operating system copy utility or using custom scripts that periodically send archived redo log files from one database to the other. The consequence is that this configuration does not provide the ease-of-use, manageability, performance, and disaster-recovery capabilities available with Data Guard.+

Hope That Helps.

Create an Object in Logical standby database in Oracle 10G

Hi,
I have logical standby database in oracle 10g R2 for reporting purpose.Now i want to create procedure in logical standby which is use to create new temp table in logical standby and contained data generated from select operation on existing table.
Can i create a new user in logical standby database,add new tablespace in logical standby which can insert,update and delete data in standby database base table?
kindly provide me the steps to implement all this.What will be effect if i set guard_Status in v$database is NONE in logical standby?
Thanks,
Shital Patel

Hi Shital,
Guard_status protects the data from being changed.
ALL- By default it is not possible for a non-privileged user to modify data on a data guard SQL apply database. This is because the database guard is automatically set to ALL.
With this level of security, only SYS user can modify the data.
STANDBY- When you set this level of security, users are able to modify data that is not maintained by the Logical apply engine.
NONE permits any users to access the standby database as long as they have correct privileges. This is the normal security for all data in the database.
You can change the guard status value from ALL to NONE in order to allow non-privileged users to modify data and Yes you can create user and extra tablespace in logical standby database..this is what the one of advantage of using Logical standby database.
SQL> ALTER DATABASE GUARD NONE;
Thanks

Primavera 6.2 SQL Database to Oracle 11g migration

Hi,
I used the migration tool to migrate a Primavera 6.2 SQL database to Oracle 11G DB. The migration tool runned successfully and I am able to login to the database using P6.2 client with no problem; however when attemptiong to update the license on the now Oracle database using the privuser account I get the following error "License could not be loaded because of error: List index out of bounds (247). Please make sure that you are using a privileged database login" the error comes up before I can browse to the location of licesne.txt file. Same procedure on a "native" Oracle P6.2 database works perfectly with no problem. Has any one run into this problem before? any help will be appreciated.

Best Reagrds,I have not seen that specifically but it appears that not all of the grants were correctly applied.
I would suggest running the schema validation tool which can be found on the knowledgebase as Solution ID: prim75459 as this will tell you what is missing/invalid.
Once you know that, you can pull the neccesary grants from the create scripts located in the cd1\install\database\scripts folder.

To create standby database using oracle 10g standared edition

my producation database is oracle 10G standard edition .Can i implement a oracle dataguard or standby database using standard edition licenses.if standby database is possiable in standard edition .what are the steps for creating a standby database using oracle 10g standard edition.

General answer is http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#BABJICBB.
For Data Guard you cannot :
- use instance parameters to automatically send archived redo logs
- use instance parameters to resolve archived redo logs gaps
- create a logical standby
- use SQL statements to do switchover / failover
- use Data Guard Broker.
