We have the following setup
primary db
==========
OPEN_MODE DATABASE_ROLE
---------- ----------------
READ WRITE PRIMARY
standby_file_management AUTO

LOGICAL STDBY
=============
OPEN_MODE DATABASE_ROLE
---------- ----------------
READ WRITE LOGICAL STANDBY
standby_file_management AUTO

PHYSICAL STDBY
==============
OPEN_MODE DATABASE_ROLE
---------- ----------------
MOUNTED PHYSICAL STANDBY
standby_file_management AUTO

All datafile paths are similar

I want to create a new tablespace on the primary DB will it be created automatically on the logical & physical standby db?

I do not have a test environment, as i have to do it on production, want to be sure if any of you guys have done this before. As of now all primary,logical,physical dbs are in sync. I don't want to disturb the replication.

Please advice.

Thanks for your response,could tell me if the below steps are correct?How to check status before & after for all dbs

how to check the replication status on primary,logical stdby, physical stdby if everything is ok BEFORE to executing

the below steps

primarydb
=======
connect sys@constr as sysdba
create tablespace per datafile 'z:\DATA\perfstat.dbf' size 200M autoextend
on;

Logical stdby db [explicitly]
=====================
connect sys@constr as sysdba
create tablespace per datafile 'z:\DATA\perfstat.dbf' size 200M autoextend on;

Physical stdby db
=============
No statements to execute, the above changes to primary will automatically get
updated here.

how to check the replication status on primary,logical stdby, physical stdby if everything
is ok AFTER to executing
the below steps

I'm not sure about logical but for physical standby database cancel managed recovery open the database in read only mode and check the tablespace on standby,after checking put back physical standby in recover managed mode.

One other option when you creating files on primary or doing normal transaction you can check the status of MRP process by this query.

SELECT  PROCESS, STATUS,SEQUENCE#,BLOCK#,BLOCKS, DELAY_MINS FROM 
               V$MANAGED_STANDBY;


You will notice that the value for MRP will keep increasing if work is going on on primary database.

I managed to create the per tablespace on the primary and automatically it got created on physical & logical stabdby, then i installed the statspac on the primary, and now the logs are not getting applied to the logical standby. Do i have to install the statspack on the standby as well.

in alert.log show this error.

In my opinion the statspack should be installed on the standby databases as well. On the logical standby you can query the dba_logstdby_events for checking the cause of failures.
