2. Introduction Cloning a database can take up a lot of time and disk space, so, we usually limit copies of our PROD database to just a few clones, such as TEST, PPRD, and UPGD. Oracle’s new Direct NFS cloning, introduced in 11gR2 and documented in 12c, blows away those time and space restrictions, allowing us to create as many clones as we need in under 2 minutes apiece utilizing 1/100’th of the disk space. CoHEsion Summit 2

3. Benefits: An Understanding of Direct NFS Cloning After attending this session, you will come away knowing how to create local Direct NFS clones (no separate DNFS server and NAS storage device server for the base database copy needed) in under 2 minutes apiece, which occupy minimal disk space. CoHEsion Summit 3

4. What is Direct NFS?

5. Oracle Direct NFS (DNFS) is an NFS (Network File System) client that provides faster and more scalable access to NFS storage located on NAS (Network-Attached Storage) storage devices. NAS appliances and their client systems typically communicate via the Network File System (NFS) protocol. NFS allows client systems to access files over the network as easily as if the underlying storage was directly attached to the client. CoHEsion Summit 5

6. What is Direct NFS? With a standard DNFS setup, you have one or more NAS storage devices, a DNFS server to connect those storage devices to your database (or other) servers using the NFS protocol, and your current database (or other) servers that access data on those NAS storage device mount points. That’s a lot of hardware, especially if you just want to clone a database! CoHEsion Summit 6

7. What is Direct NFS? Actually, all that we need is to enable and configure the Direct NFS client on our database server to loop back to the database server itself, so the DNFS client accesses a mount point mapped to a directory on the database server as a “virtual NAS storage device”, and transmits that data back and forth to the database server itself. So, we have eliminated the need for a separate NAS storage device and a separate DNFS server! CoHEsion Summit 7

8. What is a Direct NFS Clone?

9. A Direct NFS Clone consists of: 1)A base image copy of the database being cloned (this is read-only), referenced by all of the DNFS clones. 2)A mapped set of local tablespace datafiles containing the changes made to the base image data (DML, DDL) for each DNFS clone. 3)Other local Oracle tablespaces and files, such as the control file, the TEMP tablespace, and the redo logs for each DNFS clone. CoHEsion Summit 9

10. How Do We Create a Base Image Copy?

11. su - oracle. oraenv TEST mkdir -p /u01/oradata/clone_base rman target / run { configure controlfile autobackup off; set nocfau; backup as copy database format '/u01/oradata/clone_base/%U' ; } exit Note: "nocfau" is "no controlfile auto backup“; also, may need "unset TWO_TASK" after oraenv so running rman won’t give an error). CoHEsion Summit 11

12. How Do We Set Up Direct NSF Locally?

13. Create a directory for the NFS shares (nfs_shares) while logged in as root: mkdir -p /u01/nfs_shares/clonedb chown -R oracle:oinstall /u01/nfs_shares Export the NFS shares directory: Add the following line to /etc/exports: /u01/nfs_shares/clonedb *(rw,sync,no_wdelay,insecure, insecure_locks,no_root_squash) exportfs -a exportfs Shows the clonedb directory exported to the entire world: /u01/nfs_shares/clonedb CoHEsion Summit 13

14. How Do We Set Up Direct NSF Locally? Create a directory that we are going to mount on (nfs_mount) on the same server: mkdir -p /u01/nfs_mount/clonedb chown -R oracle:oinstall /u01/nfs_mount So, we are exporting /u01/nfs_shares/clonedb, and we are mounting /u01/nfs_mount/clonedb, so, NFS is actually never leaving the system. Add the NFS mount directory to /etc/fstab so that it does the mount again on server reboot (specifying the localhost for nfs_shares): myserver.myschool.edu:/u01/nfs_shares/clonedb /u01/nfs_mount/clonedb nfs rw,bg,hard,nointr,tcp,nfsvers=3,timeo=400,rsize=32768,wsize=32768,actimeo=0 0 0 Mount the NFS mount directory (the mount command reads /etc/fstab): mount -a df -h Shows: myserver.myschool.edu:/u01/nfs_shares/clonedb 1.2T 816G 305G 73% /u01/nfs_mount/clonedb CoHEsion Summit 14

15. How Do We Set Up Direct NSF Locally? Change the permissions for oradism (in the Oracle Home bin directory) to eliminate “ORA-17513: dNFS package call failed” errors: chmod 4755 /u01/app/oracle/product/11.2.0.3/dbhome_1/bin/oradism Create oranfstab file in the Oracle Home dbs directory (logged in (su) as user oracle) to declare the NFS servers you are going to use (this local NFS mount loops back to the server itself (using IP address 127.0.0.1)): su - oracle. oraenv TEST cd $ORACLE_HOME/dbs Add the following to the oranfstab file: server: myserver.myschool.edu path: 127.0.0.1 local: 127.0.0.1 export: /u01/nfs_shares/clonedb mount: /u01/nfs_mount/clonedb CoHEsion Summit 15

16. How Do We Set Up Direct NSF Locally? Enable the Direct NFS client for the Oracle Home by replacing the current (non-NFS) Oracle Disk Manager (odm) library with the NFS odm library: cd ${ORACLE_HOME}/lib ls -ltr *odm* Shows: -rw-r--r-- 1 oracle dba 7370 Sep 17 2011 libodm11.a -rw-r--r-- 1 oracle dba 12259 Sep 17 2011 libodmd11.so -rw-r--r-- 1 oracle dba 60431 Sep 17 2011 libnfsodm11.so lrwxrwxrwx 1 oracle dba 12 May 25 2012 libodm11.so -> libodmd11.so cp -p libodm11.so libodm11.so.save cp -p libnfsodm11.so libodm11.so (or, "ln –s libnfsodm11.so libodm11.so") Now, we are NFS enabled (which will be seen in the alert log when the database is started, which shows a line like “Oracle instance running with ODM: Oracle Direct NFS ODM Library Version 3.0”), with libodm11.so containing libnfsodm11.so: ls -ltr *odm* Shows: -rw-r--r-- 1 oracle dba 7370 Sep 17 2011 libodm11.a -rw-r--r-- 1 oracle dba 60431 Sep 17 2011 libodmd11.so -rw-r--r-- 1 oracle dba 12259 Sep 17 2011 libodm11.so.save -rw-r--r-- 1 oracle dba 60431 Sep 17 2011 libnfsodm11.so lrwxrwxrwx 1 oracle dba 12 May 25 2012 libodm11.so -> libodmd11.so CoHEsion Summit 16

17. Let’s Make Our First Direct NFS Clone

18. Create the base parameter file, which will be customized by the clonedb.pl script for every clone that is created from the RMAN base image copy: sqlplus / as sysdba create pfile='/u01/oradata/initbase.ora' from spfile; exit After the RMAN base image copy has been created, remove all files from that clone_base directory (such as spfile and control file, if any), leaving just the base image copies of the datafiles: cd /u01/oradata/clone_base ls -ltr rm... (i.e., remove the files without a tablespace name) CoHEsion Summit 18

19. Let’s Make Our First Direct NFS Clone Create a directory in the nfs mount directory for the first clone - let's name it "CLONE1“ (note that this maps to /u01/nfs_shares/clonedb/CLONE1): mkdir –p /u01/nfs_mount/clonedb/CLONE1 Add the CLONE1 entry to the /etc/oratab file (for ". oraenv" to use), specifying the correct ORACLE_HOME directory for the clone: CLONE1:/u01/app/oracle/product/11.2.0.3/dbhome_1:N Switch to the CLONE1 environment variables (may need "unset TWO_TASK" after this so running sqlplus won’t give an error):. oraenv CLONE1 Set the environment variables which will be used by Oracle's clonedb.pl script, specifying the master copy (the base image copy), the clone's directory, and the clone's name (SID): export MASTER_COPY_DIR=/u01/oradata/clone_base export CLONE_FILE_CREATE_DEST=/u01/nfs_mount/clonedb/CLONE1 export CLONEDB_NAME=CLONE1 export ORACLE_SID=CLONE1 CoHEsion Summit 19

20. Let’s Make Our First Direct NFS Clone Create the control file creation script (crtdb.sql), the datafile rename script (dbren.sql - which is used to map the clone's database-specific datafiles to the base image copy datafiles), and the clone's parameter file using Oracle's clonedb.pl script, specifying the base parameter file to model the clone's parameter file after, along with the two script file names that are to be created: cd /tmp perl $ORACLE_HOME/rdbms/install/clonedb.pl /u01/oradata/initbase.ora crtdb.sql dbren.sql Note: The parameter file is put into /u01/nfs_mount/clonedb/CLONE1/initCLONE1.ora (the CLONE_FILE_CREATE_DEST directory). The clonedb.pl script makes the following parameter file changes for the clone: control_files=/u01/nfs_mount/clonedb/CLONE1/CLONE1_ctl.dbf db_name=CLONE1 db_create_file_dest=/u01/nfs_mount/clonedb/CLONE1 log_archive_dest=/u01/nfs_mount/clonedb/CLONE1 CoHEsion Summit 20

21. Let’s Make Our First Direct NFS Clone If this is an Oracle 11.2.0.3 database, add the following to the clone's init.ora file (/u01/nfs_mount/clonedb/CLONE1/initCLONE1.ora): clonedb=TRUE Edit the crtdb.sql file to specify the TEST's character set: In TEST: select value from nls_database_parameters where parameter = 'NLS_CHARACTERSET'; shows: AL32UTF8 Edit crtdb.sql to contain that character set: Change last line from: CHARACTER SET WE8DEC; to: CHARACTER SET AL32UTF8; CoHEsion Summit 21

22. Let’s Make Our First Direct NFS Clone Edit the dbren.sql file to specify the full create TEMP tablespace directives, if needed, changing the two ending drop and create tablespace TEMP lines to something like: create temporary tablespace TEMP2 tempfile '/u01/nfs_mount/clonedb/CLONE1/temp_CLONE1_01.dbf' size 400064K extent management local uniform size 640K; alter database default temporary tablespace TEMP2; drop tablespace TEMP; alter tablespace TEMP2 rename to TEMP; If you have SID-specific information in your oraenv script or your banenv script, you will need to edit those scripts to include the new clone's information. CoHEsion Summit 22

23. Let’s Make Our First Direct NFS Clone Run the crtdb.sql (creates the control file) and dbren.sql (maps the base to local datafiles) scripts in CLONE1, then, create the resulting server parameter file (which is placed in $ORACLE_HOME/dbs) from the parameter file: sqlplus / as sysdba @crtdb.sql @dbren.sql select name from v$datafiles; create spfile from pfile='/u01/nfs_mount/clonedb/CLONE1/initCLONE1.ora'; exit CoHEsion Summit 23

24. Let’s Make Our First Direct NFS Clone If you get errors from dbren.sql like: ORA-01152: file 1 was not restored from a sufficiently old backup Do a recover database: In CLONE1, "show parameter arch" shows: log_archive_dest string /u01/nfs_mount/clonedb/CLONE1 In TEST, "show parameter arch" shows: log_archive_dest string /u06/oradata/TEST/ See what archive logs are available in TEST (most recent backups since the base image copy was made): ls /u06/oradata/TEST/archivelog/2013_10_13 o1_mf_1_1122_95o2vw75_.arc ls /u06/oradata/TEST/archivelog/2013_10_14 o1_mf_1_1123_95r1x9q5_.arc recover database using backup controlfile until cancel; shows: ORA-00280: change 7392764100 for thread 1 is in sequence #1122, so enter 1122 file: /u06/oradata/TEST/archivelog/2013_10_13/o1_mf_1_1122_95o2vw75_.arc shows: ORA-00280: change 7392772306 for thread 1 is in sequence #1123, so enter 1123 file: /u06/oradata/TEST/archivelog/2013_10_14/o1_mf_1_1123_95r1x9q5_.arc shows: ORA-00280: change 7392815711 for thread 1 is in sequence #1124, N/A, so enter redo log: /u06/oradata/TEST/redo_TEST_01b.rdo Log applied. Media recovery complete. alter database open resetlogs; (and, create the spfile and TEMP tablespace manually here) CoHEsion Summit 24

25. Let’s Make Our First Direct NFS Clone Congratulations! We've just made our first clone based on that base image copy of the TEST database that we created at the beginning. CoHEsion Summit 25

Let's see the base image copy directory ("-lsh" shows the actual size and the apparent size of the files): cd /u01/oradata/clone_base ls -lsh Shows that the actual size and apparent size of the datafiles are the same, with a total of 136 Gig: total 136G 51M -rw-r----- 1 oracle oinstall 51M Oct 14 16:19 data_D-TEST_I-2108832167_TS-BANAQ_FNO-4_13om9gjv 101M -rw-r----- 1 oracle oinstall 101M Oct 14 16:19 data_D-TEST_I-2108832167_TS-BANIAM_FNO-5_11om9gid 101M -rw-r----- 1 oracle oinstall 101M Oct 14 16:19 data_D-TEST_I-2108832167_TS-BANLOB_FNO-6_12om9gjg 11M -rw-r----- 1 oracle oinstall 11M Oct 14 16:19 data_D-TEST_I-2108832167_TS-CONVERSION_FNO-7_15om9gkd 23G -rw-r----- 1 oracle oinstall 23G Oct 14 16:19 data_D-TEST_I-2108832167_TS-DEVELOPMENT_FNO-10_0mom97s7 22G -rw-r----- 1 oracle oinstall 22G Oct 14 16:19 data_D-TEST_I-2108832167_TS-DEVELOPMENT_FNO-11_0nom99c9 21G -rw-r----- 1 oracle oinstall 21G Oct 14 16:19 data_D-TEST_I-2108832167_TS-DEVELOPMENT_FNO-12_0qom9dp4 21G -rw-r----- 1 oracle oinstall 21G Oct 14 16:19 data_D-TEST_I-2108832167_TS-DEVELOPMENT_FNO-8_0pom9cgv 21G -rw-r----- 1 oracle oinstall 21G Oct 14 16:19 data_D-TEST_I-2108832167_TS-DEVELOPMENT_FNO-9_0oom9ai8 1.3G -rw-r----- 1 oracle oinstall 1.3G Oct 14 16:22 data_D-TEST_I-2108832167_TS-SYSAUX_FNO-2_10om9gfe 1.5G -rw-r----- 1 oracle oinstall 1.5G Oct 14 16:22 data_D-TEST_I-2108832167_TS-SYSTEM_FNO-1_0vom9gcp 2.0G -rw-r----- 1 oracle oinstall 2.0G Oct 14 16:19 data_D-TEST_I-2108832167_TS-TESTMGR_FNO-13_0uom9g96 4.3G -rw-r----- 1 oracle oinstall 4.3G Oct 14 16:19 data_D-TEST_I-2108832167_TS-TOOLS_FNO-14_0tom9g24 6.7G -rw-r----- 1 oracle oinstall 6.7G Oct 14 16:21 data_D-TEST_I-2108832167_TS-UNDO_FNO-3_0som9fm3 15G -rw-r----- 1 oracle oinstall 15G Oct 14 16:19 data_D-TEST_I-2108832167_TS-USERS_FNO-15_0rom9ets 35M -rw-r----- 1 oracle oinstall 35M Oct 14 16:19 data_D-TEST_I-2108832167_TS-WORKFLOW_FNO-16_14om9gk6 CoHEsion Summit 27

28. What about the Direct NFS Clone Space? Let's see the clone datafile directory: cd /u01/nfs_mount/clonedb/CLONE1 ls -lsh Shows that the total size of the datafiles, etc., for CLONE1 is 372 Meg, versus the 136 Gig for the base image copy database, with the actual size of datafiles being much smaller than apparent size of those files (most of the directory size is taken up by the redo log files in CLONE1): total 372M 8.0K drwxr-x--- 3 oracle oinstall 4.0K Oct 14 16:31 CLONE1 8.6M -rw-r----- 1 oracle oinstall 8.6M Oct 14 16:36 CLONE1_ctl.dbf 101M -rw-r----- 1 oracle oinstall 101M Oct 14 16:36 CLONE1_log1.log 101M -rw-r----- 1 oracle oinstall 101M Oct 14 16:31 CLONE1_log2.log 8.0K -rw-r--r-- 1 oracle oinstall 2.0K Oct 14 16:18 initCLONE1.ora 20K -rw-r----- 1 oracle oinstall 51M Oct 14 16:31 ora_data_CLONE10.dbf 1.6M -rw-r----- 1 oracle oinstall 1.5G Oct 14 16:36 ora_data_CLONE110.dbf 20K -rw-r----- 1 oracle oinstall 2.0G Oct 14 16:31 ora_data_CLONE111.dbf 20K -rw-r----- 1 oracle oinstall 4.3G Oct 14 16:31 ora_data_CLONE112.dbf 53M -rw-r----- 1 oracle oinstall 6.7G Oct 14 16:36 ora_data_CLONE113.dbf 20K -rw-r----- 1 oracle oinstall 15G Oct 14 16:31 ora_data_CLONE114.dbf 948K -rw-r----- 1 oracle oinstall 35M Oct 14 16:31 ora_data_CLONE115.dbf 20K -rw-r----- 1 oracle oinstall 101M Oct 14 16:31 ora_data_CLONE11.dbf 20K -rw-r----- 1 oracle oinstall 101M Oct 14 16:31 ora_data_CLONE12.dbf 20K -rw-r----- 1 oracle oinstall 11M Oct 14 16:31 ora_data_CLONE13.dbf 34M -rw-r----- 1 oracle oinstall 23G Oct 14 16:31 ora_data_CLONE14.dbf...

29. Let’s Make Our Second Direct NFS Clone

30. Wanna see it again? OK. Get Your Stopwatches out! We’re going for 2 minutes here to create a clone! CoHEsion Summit 30

31. Let’s Make Our Second Direct NFS Clone Create the directory where the new clone (CLONE2) will live: mkdir -p /u01/nfs_mount/clonedb/CLONE2 Add the CLONE2 entry to the /etc/oratab file: CLONE2:/u01/app/oracle/product/11.2.0.3/dbhome_1:N Switch to the CLONE2 environment variables (may need "unset TWO_TASK" after this so running sqlplus won’t give an error):. oraenv CLONE2 Set the environment variables for CLONE2 which will be used by the clonedb.pl script: export MASTER_COPY_DIR=/u01/oradata/clone_base export CLONE_FILE_CREATE_DEST=/u01/nfs_mount/clonedb/CLONE2 export CLONEDB_NAME=CLONE2 export ORACLE_SID=CLONE2 CoHEsion Summit 31

32. Let’s Make Our Second Direct NFS Clone Run the clonedb.pl script again for the second clone: cd /tmp perl $ORACLE_HOME/rdbms/install/clonedb.pl /u01/oradata/initbase.ora crtdb.sql dbren.sql If this is an Oracle 11.2.0.3 database, add the following to the clone's init.ora file (/u01/nfs_mount/clonedb/CLONE2/initCLONE2.ora): clonedb=TRUE Edit the crtdb.sql file to specify the TEST's character set: In TEST: select value from nls_database_parameters where parameter = 'NLS_CHARACTERSET'; shows: AL32UTF8 Edit crtdb.sql to contain that character set: Change last line from: CHARACTER SET WE8DEC; to: CHARACTER SET AL32UTF8; CoHEsion Summit 32

33. Let’s Make Our Second Direct NFS Clone Edit the dbren.sql file to specify the full create TEMP tablespace directives, if needed, changing the two ending drop and create tablespace TEMP lines to something like: create temporary tablespace TEMP2 tempfile '/u01/nfs_mount/clonedb/CLONE2/temp_CLONE2_01.dbf' size 400064K extent management local uniform size 640K; alter database default temporary tablespace TEMP2; drop tablespace TEMP; alter tablespace TEMP2 rename to TEMP; If you have SID-specific information in your oraenv script or your banenv script, you will need to edit those scripts to include the new clone's information. Run the crtdb.sql and dbren.sql scripts generated by the above clonedb.pl script in the CLONE2 database, and create the spfile: sqlplus / as sysdba @crtdb.sql @dbren.sql create spfile from pfile='/u01/nfs_mount/clonedb/CLONE2/initCLONE2.ora'; exit CoHEsion Summit 33

34. Let’s Make Our Second Direct NFS Clone And, BAM! We've just made our second clone in under 2 minutes! (Was anyone timing me?!) CoHEsion Summit 34

35. Summary Oracle’s Direct NFS capability allows you to create instant database clones at the drop of a hat occupying a very small footprint any time your users need to test a new scenario. Since disk space and creation time have been minimized by DNFS clones, about the only thing you may have to contend with is memory (SGA, PGA, etc.) when having a bunch of DNFS clones open.
