TDE–How to implement TDE in your database and what to think about

This is the first part in a series of blog posts on TDE.

Many organizations are moving to TDE, and this can have a dramatic affect on your systems.

TDE impacts 2 areas

1) Post encryption compression goes away.  Encrypted data can’t be compressed.  Now why do I mention “Post encryption” ? This is because data can be compressed before encrypting.  Compressed data in your database (HCC, OLTP, basic etc.) is compressed PRIOR to encryption.  Utilizing compression in your database not only saves you disk space on your storage system, but it also saves you disk space for your backups.  The loss of compression post encryption can have many consequences you might not immediately think of

    • if you are using SSD storage that compresses blocks, you need to take into account the extra storage needed
    • If you are using a De-duplication appliance you will lose most of the benefits of de-duplication.
    • If you are compressing your backups, you will lose the benefits gained from compression (small backups and lowered network traffic).

2) Moving to TDE requires more space during the migration. Rebuilding the tablespaces with a newly encrypted copy is done by creating a second copy of each datafile (encrypted), and then removing the pre-encrypted copy.  The database switches to the new datafile when the process is complete.  This utilizes additional storage for the second copy of the datafiles.  The other migration impact is an increase in backup storage.  After encrypting tablespaces, a new level 0 backup is needed to ensure you are restoring to an encrypted copy of the data. Remember the encryption process changes all the blocks in the datafiles. I will discuss the backup implications more later.


Now I’m going to start by describing the dataset I used for testing.

In order to create this dataset I used the oewizard from Swingbench


Here are the objects and the sizes.


SEGMENT_NAME SEGMENT_TYPE TABLESPACE_NAME SPACE_USED ------------------------------ ------------------ ------------------------------ ----------- CUST_EMAIL_IX INDEX SOE 975 MB CARD_DETAILS TABLE SOE 2,048 MB CUSTOMERS_PK INDEX SOE 443 MB CARD_DETAILS_PK INDEX SOE 662 MB PRD_DESC_PK INDEX SOE 0 MB INV_WAREHOUSE_IX INDEX SOE 16 MB ADDRESS_CUST_IX INDEX SOE 703 MB ORD_SALES_REP_IX INDEX SOE 594 MB ORD_CUSTOMER_IX INDEX SOE 671 MB CUST_ACCOUNT_MANAGER_IX INDEX SOE 417 MB ORDERENTRY_METADATA TABLE SOE 0 MB ADDRESS_PK INDEX SOE 662 MB ITEM_ORDER_IX INDEX SOE 2,000 MB ADDRESSES TABLE SOE 3,392 MB ORDER_ITEMS TABLE SOE 6,976 MB ORDERS TABLE SOE 3,968 MB PRODUCT_INFORMATION TABLE SOE 0 MB LOGON TABLE SOE 1,728 MB ORDER_PK INDEX SOE 632 MB WHS_LOCATION_IX INDEX SOE 0 MB PROD_CATEGORY_IX INDEX SOE 0 MB CARDDETAILS_CUST_IX INDEX SOE 704 MB INVENTORY_PK INDEX SOE 18 MB CUST_FUNC_LOWER_NAME_IX INDEX SOE 683 MB PRODUCT_DESCRIPTIONS TABLE SOE 0 MB WAREHOUSES_PK INDEX SOE 0 MB PRODUCT_INFORMATION_PK INDEX SOE 0 MB ITEM_PRODUCT_IX INDEX SOE 1,768 MB CUST_DOB_IX INDEX SOE 528 MB PROD_NAME_IX INDEX SOE 0 MB CUSTOMERS TABLE SOE 3,328 MB WAREHOUSES TABLE SOE 0 MB INVENTORIES TABLE SOE 176 MB ORDER_ITEMS_PK INDEX SOE 2,234 MB INV_PRODUCT_IX INDEX SOE 16 MB ORD_ORDER_DATE_IX INDEX SOE 752 MB ORD_WAREHOUSE_IX INDEX SOE 709 MB PROD_SUPPLIER_IX INDEX SOE 0 MB

TOTAL 36,804 MB

Here is the total size for the data

===================================================================================================================

Total                                   38,303 MB      60,820 MB      22,517 MB


From above I can see that I am using 38 GB of space, out of the 61 GB of space allocated.

Now I created a backup set . With no compression the size of the backup set is about the size data used.

[oracle@oracle-server]$ ls -al
total 38910628
drwxrwx---. 2 oracle oracle          58 Nov 15 16:34 .
drwxrwx---. 3 oracle oracle          24 Nov 15 16:23 ..

[oracle@oracle-server]$

Just to save my spot .I’m going to create a restore point to make this the starting point of all my testing.

SQL> create restore point new_database;

Restore point created.



Now let’s look at what happens when I compress the backup of this database

Finally I took an incremental merge backup to see what happens with that.

Restoring from multiple nodes in a RAC cluster

My previous post involved backing up from all nodes in a RAC cluster.  You can find it here.

In that post I explained why it is important to use multiples nodes to increase your throughput.

In this post I will explain how to restore using multiple nodes in the clusters.

First let's start with my database and drop it.

I stopped my database and went to ASM and removed all files from the disk group.


Step 1 -- Find the DBID from the rman catalog



select db_id,REG_DB_UNIQUE_NAME from db;

     DB_ID REG_DB_UNIQUE_NAME
---------- ------------------------------
4099465517 db1
3776942889 BRYAN
3281763275 db2
2294802577 db3

There it is !  My database BRYAN has a DBID of 3776942889


Step 2 --  Create a small initfile to use to start the database nomount.



db_name='bryan'
memory_target=1G
processes = 150


Step 3 --  start the database nomount.


startup nomount;
ORACLE instance started.

Total System Global Area 1073741824 bytes
Fixed Size            2932632 bytes
Variable Size          616562792 bytes
Database Buffers      394264576 bytes
Redo Buffers           59981824 bytes


Step 4 -- Connect to RMAN using the target / and catalog {my_rman_catalog}



Recovery Manager: Release 12.1.0.2.0 - Production on Wed Aug 8 11:26:18 2018

Copyright (c) 1982, 2014, Oracle and/or its affiliates.  All rights reserved.

connected to target database: BRYAN (not mounted)
connected to recovery catalog database


Step 5 -- Set the DBID of the database.


RMAN set dbid=3776942889;

executing command: SET DBID
database name is "BRYAN" and DBID is 3776942889


Step 6 - Restore the SPFILE.



RMAN> run
2> {
3> allocate CHANNEL sbt1 DEVICE TYPE 'SBT_TAPE'  FORMAT   '%d_%U' PARMS  "SBT_LIBRARY=/u01/app/oracle/product/12.1.0.2/dbhome_1/lib/libra.so, ENV=(RA_WALLET='location=file:/u01/app/oracle/product/12.1.0.2/dbhome_1/dbs/zdlra credential_alias=zdl2ing-scan:1521/zdlra:dedicated')";
4> restore spfile;
5> }

allocated channel: sbt1
channel sbt1: SID=133 device type=SBT_TAPE
channel sbt1: RA Library (ZDLRA) SID=72F1DBDB0D05BC0FE05375AF880AE677

Starting restore at 08-AUG-2018 11:41:30

channel sbt1: starting datafile backup set restore
channel sbt1: restoring SPFILE
output file name=/u01/app/oracle/product/12.1.0.2/dbhome_1/dbs/spfilebryan1.ora
channel sbt1: reading from backup piece c-3776942889-20180808-0b
channel sbt1: piece handle=c-3776942889-20180808-0b tag=TAG20180808T093007
channel sbt1: restored backup piece 1
channel sbt1: restore complete, elapsed time: 00:00:25
Finished restore at 08-AUG-2018 11:43:22
released channel: sbt1




Step 7 - from asmcmd copy the spfile into ASM, and remove it from the OS.


ASMCMD> mkdir +datac1/bryan
ASMCMD> mkdir +datac1/bryan/parameterfile
ASMCMD> cp /u01/app/oracle/product/12.1.0.2/dbhome_1/dbs/spfilebryan1.ora +datac1/bryan/parameterfile/spfilebryan.ora
copying /u01/app/oracle/product/12.1.0.2/dbhome_1/dbs/spfilebryan1.ora -> +datac1/bryan/parameterfile/spfilebryan.ora
ASMCMD> 



Step 8 - point the initfile to use the spfile on both instances. and restart the instance nomount using the spfile


Step 9 - Modify the service to use the spfile location


srvctl modify database -db bryan -spfile '+DATAC1/bryan/parameterfile/spfilebryan.ora'


Step 10 - recreate the password file and change the service to point to it.


orapwd file=+DATAC1/bryan/PASSWORD/pwdbryan.ora dbuniquename=bryan

srvctl modify database -db bryan -pwfile '+DATAC1/bryan/PASSWORD/pwdbryan.ora'


Step 11 - Restore the controlfiles



RMAN> set dbid=3776942889;

executing command: SET DBID
database name is "BRYAN" and DBID is 3776942889

RMAN> run
2> {
3> allocate CHANNEL sbt1 DEVICE TYPE 'SBT_TAPE'  FORMAT   '%d_%U' PARMS  "SBT_LIBRARY=/u01/app/oracle/product/12.1.0.2/dbhome_1/lib/libra.so, ENV=(RA_WALLET='location=file:/u01/app/oracle/product/12.1.0.2/dbhome_1/dbs/zdlra credential_alias=zdl2ing-scan:1521/zdlra:dedicated')";
4> restore controlfile;
5> }

allocated channel: sbt1
channel sbt1: SID=568 instance=bryan1 device type=SBT_TAPE
channel sbt1: RA Library (ZDLRA) SID=72F21BF1040F9F09E05375AF880A4C78

Starting restore at 08-AUG-2018 11:59:25

channel sbt1: starting datafile backup set restore
channel sbt1: restoring control file
channel sbt1: reading from backup piece c-3776942889-20180808-0b
channel sbt1: piece handle=c-3776942889-20180808-0b tag=TAG20180808T093007
channel sbt1: restored backup piece 1
channel sbt1: restore complete, elapsed time: 00:00:02
output file name=+DATAC1/BRYAN/CONTROLFILE/current.708.983620771
output file name=+DATAC1/BRYAN/CONTROLFILE/current.710.983620771
Finished restore at 08-AUG-2018 11:59:31
released channel: sbt1


Step 11 - Mount the database on all the nodes.


srvctl start database -d bryan -o mount

Step 12 - Connect to rman using the service, and restore the database.


rman

Recovery Manager: Release 12.1.0.2.0 - Production on Wed Aug 8 12:51:41 2018

Copyright (c) 1982, 2014, Oracle and/or its affiliates.  All rights reserved.

RMAN> connect target sys/bryan@bryan

connected to target database: BRYAN (DBID=3776942889, not open)

RMAN> connect catalog /@zdl2ing-scan:1521/zdlra:dedicated

connected to recovery catalog database

RMAN> restore database;




Step 13. - Now let's check the log and make sure it restoring across all nodes.


Starting restore at 08-AUG-2018 12:52:07

channel ORA_SBT_TAPE_8: RA Library (ZDLRA) SID=72F2D8C482E695ACE05376AF880A4989


OK.. I can see it is restoring on both instances.

Step 14 - shutdown down all instances


srvctl stop database -d bryan

Step 15 - Start up the first instance mount in RMAN and recover the database.


RMAN> startup mount;

Step 16  - Open the instance and startup the other instances.


That's it !

Backing up a RAC database with all nodes

Backing up a RAC environment from multiple DB nodes


I've been working with many customers who have never performed a multi-node backup for a RAC database.

If you didn't already know, in a RAC environment you can backup from more than 1 DB node.

Backing up from multiple DB nodes can be very important for a large multi-terabyte database to give you faster backup times.


** Keep in mind these throughput numbers would be the same for restore capability.

PART 1 - WHY


Why would I want to go through the trouble of backing up on multiple nodes ?

When looking at backup rates, the number to keep in mind is the backup rate for each network speed.

1   Gb/s  == 350 GB/hr
10 Gb/s == 3.5 TB/hr
25 Gb/s == 8.8 TB/hr

**  Note that networks are measured in small "b" which is bits/seconds
**  Database size is measured in large "B" which is Bytes.

The chart below gives you an idea of the impact of adding active network ports, and how the speed of the ports affects the backup throughput.
















Using this chart you can calculate how long it will take to backup your large database.

Here is the example of the number of hours it would take to backup a 50 T database..





PART 2 -  How ?


When performing a backup, the backup process uses channels.  I'm guessing you probably already knew that.  
Each allocated channel connects to a database instance and sends the backup through that channel to the backup location (disk, media manager, etc).
By default the allocated channel connects to the database instance that the RMAN process is executed from.
What this means is... if you are "inst_id 1" and execute a backup, all channels will be connected to "inst_id 1".

This can be changed within the channel allocation by using a channel parameter named "CONNECT".

The connect (as you expect) uses an ID and Password (or a wallet) to connect to a specific service, or by specifying an EZ Connect string.

For my example I am going to use a configure channel setting and a common service that is shared across all nodes and let it balance. the other options are

  • Create a specific service to control which instances are available for backing up.  
  • Manually allocate channels and specify the instance name in the connection.

Step 1 - Create a user for backing up


I'm going assume you are already on 12c, which contains the sysbackup role.
I'm going to create a user ,"backup_only", specifically for backing up, and I am going to use a complicated password.
Next,  I am going to grant that user sysbackup privlege.

SQL  create user backup_only identified by kkk3223490sf9090fjkljkl3590;

User created.

SQL   grant sysbackup to backup_only;

Grant succeeded.




Step 2 - Change the channel configuration to use this user


Now I am going to configure my channel to use this user for the connect clause.

Below is the statement I'm executing.  ** Notice I added the "as sysbackup" to the connection.

CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE' connect 'backup_only/kkk3223490sf9090fjkljkl3590@bryan as sysbackup' FORMAT   '%d_%U' PARMS  "SBT_LIBRARY=/u01/app/oracle/product/12.1.0.2/dbhome_1/lib/libra.so, ENV=(RA_WALLET='location=file:/u01/app/oracle/product/12.1.0.2/dbhome_1/dbs/zdlra credential_alias=zdl2ing-scan:1521/zdlra:dedicated')";



This is for a ZDLRA so I have the additional information it needs for the library etc.

Notice that the I am including the id/password and tnsnames entry in the connection string.

This is what happens when I execute the configure command.



RMAN  
RMAN CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE' connect * FORMAT   '%d_%U' PARMS  "SBT_LIBRARY=/u01/app/oracle/product/12.1.0.2/dbhome_1/lib/libra.so, ENV=(RA_WALLET='location=file:/u01/app/oracle/product/12.1.0.2/dbhome_1/dbs/zdlra credential_alias=zdl2ing-scan:1521/zdlra:dedicated')";

One thing that stands out is that the connection information doesn't appear in the channel.  it is obfuscated by the '*' even though it is stored.


Step 3 - Execute backup


I can now execute my backup from either OEM, or from the command line.

This can be monitored (to ensure multiple nodes are used) by looking at the channel allocation in the output log of the backup.



Starting backup at 2018-08-08 09:27:17

allocated channel: ORA_SBT_TAPE_8


Above is the example from my output.. You can see the that there were 8 channels allocated, and 5 of the channels were on the first instance and 3 were allocated on the second instance.

That's all there is to it !!

Next blog post is going to be restoring across multiple nodes in a RAC cluster.

Multi-tenant backup and recover part 2

This blog is a followup on both backing up/recovering  a multi-tenant and restore/recovery prioritization.

In my last blog I went through the trace files on the recovery of a database.  I showed where it will ALWAYS go through any incremental backups before going to the archive logs.

WELL ---  I found an exception to this with PDB's on 12.2

Here's the scenario..

When perform a Point in Time recovery of a PDB database, it will not use the incremental backups.

In my test I created a PDB and performed a full backup along with 2 incremental backups.
After the second backup, I created a restore point.

Here is where the restore point is.


QL> select a.name,b.name,scn from v$restore_point a,v$pdbs b where a.con_id=b.con_id;

RESTORE POINT NAME                  PDB NAME                 SCN                                                
----------------------------------- ----------------      ------------
                                                
TEST                                 PDB1                  1543086 


Here is what I have for RMAN backups

You will note that I have 3 backupsets

  • Level 0  -- Ckp SCN  1541202

  • Level 1 -- Ckp SCN  1542930
  • Level 1 -- Ckp SCN 1542195
The restore point (SCN 1543086)  falls directly between the first level 1 and the second level 1

BUT.  here is the recovery log
it doesn't use the incrementals and goes straight to the archive logs.

When going through the trace file here is the clue that it can't use the incremental backup for a PITR.

I see this message for all the datafiles

"Stop scn (1543359) is in the future of until scn (0) with no catalog, do not trust stopSCN"

Then I see this message "sys.dbms_backup_restore.recoverCancel"

I believe that PDB's are special when it comes to PITR.

The PDB has information that is contained in the CDB,  Performing a incremntal backup of the CDB will affect information for all PDB's.  The only choice recovery has is to use the archive logs for more granularity.

Oracle RMAN restore/recovery prioritization

This blog post is on what happens when you ask RMAN to restore and recover your database or a portion of your database (like a datafile).

This came up with a colleague who asked about the order of recovery.  The question was "If my archive logs are on disk for 48 hours, I performed a full backup 36 hours ago (to SBT_TAPE) and an incremental backup 12 hours ago (to SBT_TAPE), after restoring from SBT_TAPE, will it recover from the archive logs on disk, or will it go to tape for the incremental backup first ?

Well the answer is in the manual here.


Incremental Backups and Archived Redo Log Files
Except for RECOVER BLOCK, RMAN can use both incremental backups and archived redo log files for recovery. RMAN uses the following search order:
  1. Incremental backup sets on disk or tape
  2. Archived redo log files on disk
  3. Archived redo log backups on disk
  4. Archived redo log backup sets on tape

Now let's see this in action.

In my scenario, I am using the "USERS" tablespace.  The datafile I'm going to drop is datafile 7.

Let's walk down what happens at each SCN interval.

OK.. Now we have backups on disk (full and level 1) to restore and recover from.


First let's do the restore of datafile 7

Now let's do the recovery of datafile 7 and watch what happens.

You can see in the recovery, there are 2 steps performed, but this isn't whole picture.

 Step 1 Restore all incremental backups.

using channel ORA_DISK_1
channel ORA_DISK_1: starting incremental datafile backup set restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set
destination for restore of datafile 00007: D:\APP\BGRENN\VIRTUAL\ORADATA\ORCL\USERS01.DBF

So there are the steps that RMAN goes through


With RMAN the restore/recovery is 3 steps and works like this.  

RESTORE Process:
  1. Restore the necessary pieces of the database

RECOVER Process:

  1. Find and recover incremental backups of the database to bring the SCN as close as close as possible to the recovery point.

     NOTE : this happens as one process.  RMAN reads the backup sets and applies the blocks as it processes the backup sets,  Like a full restore, the backupset is streamed into the RMAN channels, and RMAN writes the necessary blocks to the files. 

Media recovery :
 
    NOTE : From an RMAN standpoint, media recovery is archive log processing only.  Incremental backup processing is considered recover

3) Identify the archive logs needed for recovery
4) Validate archive logs needed are on disk, and if not restore archive logs
5) recover database using archive logs on disk
