Some DBA stuff and lots of Oracle Data Guard

Get the Most out of Oracle Data Guard – The material

Posted on September 29, 2017 by Ludovico

Here we go: as usual, the feedback that I usually get after my talks (specifically, after POUG High Five conference), is if I will share my demo scripts and material.

Sadly, the demos I am doing for my presentation “Get the most out of Oracle Data Guard” are quite tied to an environment built for the purpose of the demos. So, do not expect to get scripts easy to use as is, but rather to get some ideas beyond the demo themselves.

I hope they will help to get the whole picture.

Of course, if you need to implement a cloning strategy based on Data Guard or any other solution that I describe in this post, please feel free to contact me, I will be glad to help you implement it in your environment.

Purpose:

Create a new snapshot of a standby database by apply-off, backup controlfile to trace, copy init, acfs snap, apply-on.

Optional Arguments:

-u <db_unique_name> : name of the db_unique_name of the source database. if not specified, it will be taked from the source db, but it must be mounted!

this parameter is used only for pattern replacement inside control file trace and init file.

examples:

$basename -b stout -s stout_save.Wed -d poug2648

will clone stout from snapshot $baseACFS/.ACFS/snaps/stout_save.Wed to poug2648

THE EXISTING DESTINATION DATABASE SNAPSHOT WILL BE DROPPED!!

12.1.0.2 Bundle Patch 170718 breaks Data Guard and Duplicate from active database

Posted on September 14, 2017 by Ludovico

Recently my customer patched its 12.1.0.2 databases with the Bundle Patch 170718 on the new servers (half of the customer’s environment). The old servers are still on 161018 Bundle Patch.

We realized that we could not move anymore the databases from the old servers to the new ones because the duplicate from active database was failing with this error:

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

ORA-17630: Mismatch in the remote file protocol version client 2 server 3

The last lines shows the same error that Franck blogged about some months ago.

Oracle 12.2 had introduced incompatibility with previous releases in remote file transfer via SQL*Net. At least this is what it seems. According to Oracle, this is due to a bugfix present in Oracle 12.2

Now, the bundle patch that we installed on BP 170718 contains the same bugfix (Patch for bug 18633374).

So, the incompatibility happens now between databases of the same “Major Release” (12.1.0.2).

There are two possible workarounds:

Apply the same patch level on both sides (BP170718 in my case)
Apply just the patch 18633374 on top of your current PSU/DBBP (a merge might be necessary).

We used the second approach and now we can setup Data Guard again to move our databases without downtime:

oracle@oldserver $ opatch lspatches
18633374;   <<<<<< FIX!
24340679;DATABASE BUNDLE PATCH: 12.1.0.2.161018 (24340679)

Oracle Active Data Guard and Global Data Services in Action!

Posted on December 4, 2015 by Ludovico

In a few days I will give a presentation at UKOUG Tech15 about Global Data Services, it will be the first time that I present this session.

I usually like to give the link to the material to my audience, so here we go:

Credits

I have to give special credits to my colleague Robert Bialek. I’ve got a late confirmation for this session and my slide deck was not ready at all, so I have used a big part of his original work. Most of the content included in the slides has been created by Robert, not me. (Thank you for your help! :-))

My Collaborate 14 articles about Active Data Guard 12c and Policy Managed Databases

Posted on January 20, 2015 by Ludovico

After almost 1 year, I’ve decided to publish these articles on my Slideshare account. You may have already seen them in the IOUG Collaborate 14 conference content or in the SOUG Newsletter 2014/4. Nothing really new, but I hope you’ll still enjoy them.

Cloning a PDB with ASM and Data Guard (no ADG) without network transfer

Posted on December 16, 2014 by Ludovico

Ok, if you’re reading this post, you may want to read also the previous one that explains something more about the problem.

Briefly said, if you have a CDB running on ASM in a MAA architecture and you do not have Active Data Guard, when you clone a PDB you have to “copy” the datafiles somehow on the standby. The only solution offered by Oracle (in a MOS Note, not in the documentation) is to restore the PDB from the primary to the standby site, thus transferring it over the network. But if you have a huge PDB this is a bad solution because it impacts your network connectivity. (Note: ending up with a huge PDB IMHO can only be caused by bad consolidation. I do not recommend to consolidate huge databases on Multitenant).

So I’ve worked out another solution, that still has many defects and is almost not viable, but it’s technically interesting because it permits to discover a little more about Multitenant and Data Guard.

The three options

At the primary site, the process is always the same: Oracle copies the datafiles of the source, and it modifies the headers so that they can be used by the new PDB (so it changes CON_ID, DBID, FILE#, and so on).

On the standby site, by opposite, it changes depending on the option you choose:

Option 1: Active Data Guard

If you have ADG, the ADG itself will take care of copying the datafile on the standby site, from the source standby pdb to the destination standby pdb. Once the copy is done, the MRP0 will continue the recovery. The modification of the header block of the destination PDB is done by the MRP0 immediately after the copy (at least this is what I understand).

ADG_PDB_copy

Option 2: No Active Data Guard, but STANDBYS=none

In this case, the copy on the standby site doesn’t happen, and the recovery process just add the entry of the new datafiles in the controlfile, with status OFFLINE and name UNKNOWNxxx. However, the source file cannot be copied anymore, because the MRP0 process will expect to have a copy of the destination datafile, not the source datafile. Also, any tentative of restore of the datafile 28 (in this example) will give an error because it does not belong to the destination PDB. So the only chance is to restore the destination PDB from the primary.

Option 3: No Active Data Guard, no STANDBYS=none

This is the case that I want to explain actually. Without the flag STANDBYS=none, the MRP0 process will expect to change the header of the new datafile, but because the file does not exist yet, the recovery process dies.
We can then copy it manually from the source standby pdb, and restart the recovery process, that will change the header. This process needs to be repeated for each datafile. (that’s why it’s not a viable solution, right now).

Let’s try it together:

The Environment

Primary

08:13:08 SYS@CDBATL_2> select db_unique_name, instance_name from v$database, gv$instance;

DB_UNIQUE_NAME                 INSTANCE_NAME
------------------------------ ----------------
CDBATL                         CDBATL_2
CDBATL                         CDBATL_1

08:13:08 SYS@CDBATL_2> select db_unique_name, instance_name from v$database, gv$instance;

DB_UNIQUE_NAME INSTANCE_NAME

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

CDBATL CDBATL_2

CDBATL CDBATL_1

Standby

07:35:56 SYS@CDBGVA_2> select db_unique_name, instance_name from v$database, gv$instance;

DB_UNIQUE_NAME                 INSTANCE_NAME
------------------------------ ----------------
CDBGVA                         CDBGVA_1
CDBGVA                         CDBGVA_2

07:35:56 SYS@CDBGVA_2> select db_unique_name, instance_name from v$database, gv$instance;

DB_UNIQUE_NAME INSTANCE_NAME

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

CDBGVA CDBGVA_1

CDBGVA CDBGVA_2

The current user PDB (any resemblance to real people is purely coincidental 😉 #haveUSeenMaaz):

08:14:31 SYS@CDBATL_2> select open_mode, name from gv$pdbs where name='MAAZ';

OPEN_MODE  NAME
---------- ------------------------------
OPEN       MAAZ
OPEN       MAAZ

08:14:31 SYS@CDBATL_2> select open_mode, name from gv$pdbs where name='MAAZ';

OPEN_MODE NAME

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

OPEN MAAZ

Cloning the PDB on the primary

First, make sure that the source PDB is open read-only

08:45:54 SYS@CDBATL_2> alter pluggable database maaz close immediate instances=all;

Pluggable database altered.

08:46:20 SYS@CDBATL_2> alter pluggable database maaz open read only instances=all;

Pluggable database altered.

08:46:32 SYS@CDBATL_2> select open_mode, name from gv$pdbs where name='MAAZ' ;

OPEN_MODE  NAME
---------- ------------------------------
READ ONLY  MAAZ
READ ONLY  MAAZ

08:45:54 SYS@CDBATL_2> alter pluggable database maaz close immediate instances=all;

Pluggable database altered.

08:46:20 SYS@CDBATL_2> alter pluggable database maaz open read only instances=all;

Pluggable database altered.

08:46:32 SYS@CDBATL_2> select open_mode, name from gv$pdbs where name='MAAZ' ;

OPEN_MODE NAME

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

READ ONLY MAAZ

Then, clone the PDB on the primary without the clause STANDBYS=NONE:

08:46:41 SYS@CDBATL_2> create pluggable database LUDO from MAAZ;

Pluggable database created.

08:46:41 SYS@CDBATL_2> create pluggable database LUDO from MAAZ;

Pluggable database created.

Review the clone on the Standby

At this point, on the standby the alert log show that the SYSTEM datafile is missing, and the recovery process stops.

Managed Standby Recovery not using Real Time Apply

Mon Dec 15 17:46:11 2014

Recovery interrupted!

Recovery stopped due to failure in applying recovery marker (opcode 17.34).

Datafiles are recovered to a consistent state at change 10433175 but controlfile could be ahead of datafiles.

MRP0: Background Media Recovery process shutdown (CDBGVA_2)

One remarkable thing, is that in the standby controlfile, ONLY THE SYSTEM DATAFILE exists:

We need to fix the datafiles one by one, but most of the steps can be done once for all the datafiles.

Copy the source PDB from the standby

What do we need to do? Well, the recovery process is stopped, so we can safely copy the datafiles of the source PDB from the standby site because they have not moved yet. (meanwhile, we can put the primary source PDB back in read-write mode).

Do the magic

Now there’s the interesting part: we need to assign the datafile copies of the maaz PDB to LUDO.

Sadly, the OMF will create the copies on the bad location (it’s a copy, to they are created on the same location as the source PDB).

We cannot try to uncatalog and recatalog the copies, because they will ALWAYS be affected to the source PDB. Neither we can use RMAN because it will never associate the datafile copies to the new PDB. We need to rename the files manually.

It’s better to uncatalog the datafile copies before, so we keep the catalog clean:

Then, because we cannot rename files on a standby database with standby file management set to AUTO, we need to put it temporarily to MANUAL.

then we need to set back the standby_file_management=auto or the recover will not start:

We can now restart the recovery.

The recovery process will:
– change the new datafile by modifying the header for the new PDB
– create the entry for the second datafile in the controlfile
– crash again because the datafile is missing

I know there’s no practical use of this procedure, but it helps a lot in understanding how Multitenant has been implemented.

I expect some improvements in 12.2!!

Tales from the Demo Grounds part 2: cloning a PDB with ASM and Data Guard (no ADG)

Posted on November 20, 2014 by Ludovico

In my #OOW14 presentation about MAA and Multitenant, more precisely at slide #59, “PDB Creation from other PDB without ADG*”, I list a few commands that you can use to achieve a “correct” Pluggable Database clone in case you’re not using Active Data Guard.

What’s the problem with cloning a PDB in a MAA environment without ADG? If you’ve attended my session you should know the answer…

If you read the book “Data Guard Concepts and Administration 12c Release 1 (12.1)“, paragraph 3.5 Creating a PDB in a Primary Database, you’ll see that:

If you plan to create a PDB as a clone from a different PDB, then copy the data files that belong to the source PDB over to the standby database. (This step is not necessary in an Active Data Guard environment because the data files are copied automatically when the PDB is created on the standby database.)

But because there are good possibilities (99%?) that in a MAA environment you’re using ASM, this step is not so simple: you cannot copy the datafiles exactly where you want, it’s OMF, and the recovery process expects the files to be where the controlfile says they should be.

So, if you clone the PDB, the recovery process on the standby doesn’t find the datafiles at the correct location, thus the recovery process will stop and will not start until you fix manually. That’s why Oracle has implemented the new syntax “STANDBYS=NONE” that disables the recovery on the standby for a specific PDB: it lets you disable the recovery temporarily while the recovery process continues to apply logs on the remaining PDBs. (Note, however, that this feature is not intended as a generic solution for having PDBs not replicated. The recommended solution in this case is having two distinct CDBs, one protected by DG, the other not).

With ADG, when you clone the PDB on the primary, on the standby the ADG takes care of the following steps, no matter if on ASM or FS:

recover up to the point where the file# is registered in the controlfile
copy the datafiles from the source DB ON THE STANDBY DATABASE (so no copy over the network)
rename the datafile in the controlfile
continue with the recovery

If you don’t have ADG, and you’re on ASM, Oracle documentation says nothing with enough detail to let you solve the problem. So in August I’ve worked out the “easy” solution that I’ve also included in my slides (#59 and #60):

SQL> create pluggable database DEST from SRC standbys=none;
RMAN> backup as copy pluggable database DEST format ‘/tmp/dest%f.dbf’;
$ scp /tmp/dest*.dbf remote:/tmp
RMAN> catalog start with ‘/tmp/dest’
RMAN> set newnamefor pluggable database DEST to new;
RMAN> restore pluggable database DEST;
RMAN> switch pluggable database DEST to copy;
DGMGRL> edit database ‘STBY’ set state=’APPLY-OFF’;
SQL> Alter pluggable database DEST enable recovery;
DGMGRL> edit database ‘STBY’ set state=’APPLY-ON’;

Once at #OOW14, after endless conversations at the Demo Grounds, I’ve discovered that Oracle has worked out the very same solution requiring network transfer and that it has been documented in a new note.

Making Use of the STANDBYS=NONE Feature with Oracle Multitenant (Doc ID 1916648.1)

This note is very informative and I recommend to read it carefully!

What changes (better) in comparison with my first solution, is that Oracle suggests to use the new feature “restore from service”:

RMAN> run{
2> set newname for pluggable database DEST to new;
3> restore pluggable database DEST from service prim;
4> switch datafile all;
5> }

RMAN> run{

2> set newname for pluggable database DEST to new;

3> restore pluggable database DEST from service prim;

4> switch datafile all;

5> }

I’ve questioned the developers at the Demo Grounds about the necessity to use network transfer (I had the chance to speak directly with the developer who has written this piece of code!! :-)) and they said that they had worked out only this solution. So, if you have a huge PDB to clone, the network transfer from the primary to standby may impact severely your Data Guard environment and/or your whole infrastructure, for the time of the transfer.

Of course, I have a complex, undocumented solution, I hope I will find the time to document it, so stay tuned if you’re curious! 🙂

Tales from Demo Grounds part 1: Clone PDBs while open READ-WRITE

Posted on November 6, 2014 by Ludovico

DISCLAIMER: I’ve got this information by chatting with Oracle developers at the Demo Grounds. The functionality is not documented yet and Oracle may change it at its sole discretion. Please refer to the documentation if/when it will be updated 😉

In one of my previous posts named “A PDB is cloned while in read-write, Data Guard loose its marbles (12.1.0.2, ORA-19729)” I’ve blogged about a weird behaviour:

The documentation states that you can create a pluggable database from another one only if the source PDB is open read-only.

Indeed, If I try to clone it when the source PDB is MOUNTED, I get error ORA-65036:

15:44:24 SYS@CDBATL_1> select inst_id, name, open_mode from gv$pdbs where name='MAAZ';

INST_ID NAME OPEN_MODE
---------- ------------------------------ ----------
1 MAAZ MOUNTED
2 MAAZ MOUNTED

15:53:43 SYS@CDBATL_1> create pluggable database ludo from maaz;
create pluggable database ludo from maaz
*
ERROR at line 1:
ORA-65036: pluggable database MAAZ not open in required mode

15:44:24 SYS@CDBATL_1> select inst_id, name, open_mode from gv$pdbs where name='MAAZ';

INST_ID NAME OPEN_MODE

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

1 MAAZ MOUNTED

2 MAAZ MOUNTED

15:53:43 SYS@CDBATL_1> create pluggable database ludo from maaz;

create pluggable database ludo from maaz

ERROR at line 1:

ORA-65036: pluggable database MAAZ not open in required mode

The weird behavior is that if you do it when the source is in read-write mode, it works from release 12.1.0.2 (onward?)

I’ve questioned the developers at the DEMO Grounds and they have confirmed that:

With the 12.1.0.2, they have initially planned to disclose this functionality (clone PDBS in READ-WRITE).
That they had problems in making it work with an Active Data Guard environment (a-ah! so my post was not completely wrong)
Finally they have released it as undocumented feature
In the next release “they will fix it, maybe” and document it
The process of cloning the PDB anyway freeze the transactions on the source

I hope that this update helps clarifying both the behavior and my previous post about this problem! 🙂
