Bulk Exadata Patching

After more than 11 year from the launch Oracle Exadata Machine has become popular on many companies across industries, making administrators, developers and final users almost unanimously satisfied about performance and availability.

But also, on Exadata there are cumbersome maintenance activities like patching.

Most of my Exadata customers have acquired 2 non-full RACKs, which makes the patching effort quite reasonable; but recently I started working on a project with multiple full RACKs, with tens of Storage Servers, Compute Nodes and hundreds of Virtual Machines…

A very challenging environment, especially when it came to patching…

Patching all the systems using the standard patchmgr utiliy was not acceptable, therefore I had to replace my standard patching procedure with a new one offering automation and scalability.

At this subject Oracle provides few handy options:

Patching Exadata Infrastructure

  • Storage Server Patching via http/https server: starting with Oracle Exadata System Software release 18.1.0.0.0, it is possible to patch the Storage Servers using an external http server hosting the new software image. The activitiy can be scheduled up to one week before the installation, allowing on each Cell the Management Server (MS) to start downloading and run pre-checks in advance. MS interrupts the software upgrade and generates an alert if the Cell does not comply with all pre-requisites.
  • Unbreakable Linux Network: ULN offers software patches, updates, and fixes for Oracle Linux and Oracle VM. The implementation of a local YUM repository leverages the patch automation of the bare metal OS or dom0/domU.
  • InfiniBand Switch: standard rolling upgrade patching procedure using patchmgr.

Patching Grid Infrastructure & RDBMS

  • GI & RDBMS: those components are patched using the standard Oracle tools common to all platforms, but the entire process has been parallalized using OS tools like dcli commands.

Exadata Deployment with Elastic Configuration

Recently, for one of my customers, I had the chance to install a couples of Exadata X7-2 using the new Elastic Configuration. The major benefits of using Elastic Configuration consists in the possibility to acquire the Exadata Machine with almost any possible combination of Database Nodes and Storage Cells.

In the past we were used to standard Oracle pre-defined Exadata Machine configurations: Eighth Rack, Quarter Rack, Half Rack and Full Rack, which is still possible, but not flexible enough.

The pictures below highlight the differences between the two configurations:

Edadats_Classiv_vs_Elastic

source: Oracle Data Sheet Exadata Database Machine X7-2

 

Deployment Exadata Elactic Configuration

The elastic configuration process automates the initial IP address allocations to databasenodes and storage cells, regardless the ordered configuration.  The Exadata Machine is connected to the InfiniBand switches using a standard cabling methodology which allows to determinate the node’s location in the rack. This information is therefore used when the nodes are powered up for the first time in order to assign the initial default IPs.

The final result is the Exadata Machine installed with six Oracle VMs, and three Grid Infrastructure clusters each one running a test RAC database.

 

 

Grid Management DB filling up ASM disk space

Recently I discovered on Oracle Grid Infrastructure 12cR2 that the ASM disk group hosting the Management DB (-MGMTDB) was filling up the disk space very quickly.

This is due to a bug on the oclumon data purge procedure.

To fix the problem, two possibilities are available:

  1. Recreate the Management DB
  2. Manually truncate the tables not purged and shrinking the Tablespace Size

 

Below are described the two options.

 

Option 1 – Recreate the Management DB

As root user on each cluster node:

# /u01/app/12.2.0.1/grid/bin/crsctl stop res ora.crf -init
# /u01/app/12.2.0.1/grid/bin/crsctl modify res ora.crf -attr ENABLED=0 -init

 

As Grid from the local node hosting the Management Database Instance run the commands:

$ /u01/app/12.2.0.1/grid/bin/srvctl status mgmtdb
$ /u01/app/12.2.0.1/grid/bin/dbca -silent -deleteDatabase -sourceDB -MGMTDB
Connecting to database

9% complete
14% complete
19% complete
23% complete
28% complete
47% complete
Updating network configuration files
48% complete
52% complete
Deleting instance and datafiles
76% complete
100% complete

 

How to recreate the MGMTDB:

$ /u01/app/12.2.0.1/grid/bin/dbca -silent -createDatabase -createAsContainerDatabase true -templateName MGMTSeed_Database.dbc
-sid -MGMTDB
-gdbName _mgmtdb
-storageType ASM
-diskGroupName GIMR
-datafileJarLocation <GI HOME>/assistants/dbca/templates
-characterset AL32UTF8
-autoGeneratePassword           
-skipUserTemplateCheck

 

Create the pluggable GIMR database

$ /u01/app/12.2.0.1/grid/bin/mgmtca -local

 


 

Option 2 – Manually truncate the tables

 

As root user stop and disable ora.crf resource on each cluster node:

# /u01/app/12.2.0.1/grid/bin/crsctl stop res ora.crf -init
# /u01/app/12.2.0.1/grid/bin/crsctl modify res ora.crf -attr ENABLED=0 -init

 

Connect to MGMTDB and identify the segments to truncate:

export ORACLE_SID=-MGMTDB
$ORACLE_HOME/bin/sqlplus / as sysdba
SQL> select pdb_name from dba_pdbs where pdb_name!='PDB$SEED';

SQL> alter session set container=GIMR_DSCREP_10;

Session altered.

SQL> col obj format a50
SQL> select owner||'.'||SEGMENT_NAME obj, BYTES from dba_segments where owner='CHM' order by 2 asc;

 

Likely those two tables are much bigger than the rest :

  • CHM.CHMOS_PROCESS_INT_TBL
  • CHM.CHMOS_DEVICE_INT_TBL

Truncate the tables:

SQL> truncate table CHM.CHMOS_PROCESS_INT_TBL;
SQL> truncate table CHM.CHMOS_DEVICE_INT_TBL;

 

Then if needed shrink the tablespace and job done!

 


 

RHEL 7.4 fails to mount ACFS File System due to KMOD package

After a fresh OS installation or an upgrade to RHEL 7.4, any attempt to install ACFS drivers will fail with the following message: “ACFS-9459 ADVM/ACFS is not supported on this OS version”

The error persists even if the Oracle Grid Infrastructure software includes the  Patch 26247490: 12.2 ACFS MODULE ERRORS & CRASH DURING MODULE LOAD & UNLOAD WITH OL7U4 RHCK.

 

This problem has been identified by Oracle with  BUG 26320387 – 7.4 kmod weak-modules not checking kABI compatibility correctly

And by Red Hat  Bugzilla bug:  1477073 – 7.4 kmod weak-modules –dry-run changed output format missing ‘is compatible’ messages.

root@oel7node06:/u01/app/12.2.0.1/grid/crs/install# /u01/app/12.2.0.1/grid/bin/acfsroot install
ACFS-9459: ADVM/ACFS is not supported on this OS version: '3.10.0-514.6.1.el7.x86_64'

root@oel7node06:~# /sbin/lsmod | grep oracle
oracleadvm 776830 7
oracleoks 654476 1 oracleadvm
oracleafd 205543 1

 

The current Workaround consists in downgrade the version of the kmod  RPM to  kmod-20-9.el7.x86_64.

root@oel7node06:~# yum downgrade kmod-20-9.el7

 

After the package downgrade the ACFS drivers are correcly loaded:

root@oel7node06:~# /sbin/lsmod | grep oracle
oracleacfs 4597925 2
oracleadvm 776830 8
oracleoks 654476 2 oracleacfs,oracleadvm
oracleafd 205543 1

 


 

 

 

Adding flexibility to Oracle GI Implementing Multiple SCANs

Nowadays the business requirements force the IT to implement the more and more sophisticated and consolidated environments without compromising availability, performance and flexibility of each application running on it.

In this post, I explain how to improve the Grid Infrastructure Network flexibility, implementing multiple SCANs and how to associate one or multiple networks to the Oracle databases.

To better understand the reasons for such type of implementation, below are listed few common use cases:

  • Applications are deployed on different/dedicated subnets.
  • Network isolation due to security requirement.
  • Different database protocols are in use (TCP, TCPS, etc.).

 

 

Single Client Access Name (SCAN)

By default on each Oracle Grid Infrastructure cluster, indipendently from the number of nodes, one SCAN with 3 SCAN VIPs is created.

Below is depicted the default Oracle Clusterware network/SCAN configuration.

 

Single_Scan_Listener

 

Multiple Single Client Access Name (SCAN) implementation

Before implemeting additional SCANs, the OS provisioning of new network interfaces or new VLAN Tagging has to be completed.

The current example uses the second option (VLAN Tagging), and the bond0 interface is an Active/Active setup of two 10gbe cards, to which a VLAN tag has been added.

Below is represented the customized Oracle Clusterware network/SCAN configuration, having added a second SCAN.

 

Multi_Scan_Listeners

 

Step-by-step implementation

After completing the OS network setup, as grid owner add the new interface to the Grid Infrastructure:

grid@host01a:~# oifcfg setif -global bond0.764/10.15.69.0:public

grid@host01a:~# oifcfg getif
eno49 192.168.7.32 global cluster_interconnect,asm
eno50 192.168.9.48 global cluster_interconnect,asm
bond0 10.11.8.0 global public
bond0.764 10.15.69.0 global public
grid@host01a:~#

 

Then as root create the network number 2 and disply the configuration:

root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add network -netnum 2 -subnet 10.15.69.0/255.255.255.0/bond0.764 -nettype STATIC

root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl config network -netnum 2
Network 2 exists
Subnet IPv4: 10.15.69.0/255.255.255.0/, static
Subnet IPv6:
Ping Targets:
Network is enabled
Network is individually enabled on nodes:
Network is individually disabled on nodes:

 

As root user add the node VIPs:

root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add vip -node host01a -netnum 2 -address host01b-vip.emilianofusaglia.net/255.255.255.0
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add vip -node host02a -netnum 2 -address host02b-vip.emilianofusaglia.net/255.255.255.0
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add vip -node host03a -netnum 2 -address host03b-vip.emilianofusaglia.net/255.255.255.0
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add vip -node host04a -netnum 2 -address host04b-vip.emilianofusaglia.net/255.255.255.0
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add vip -node host05a -netnum 2 -address host05b-vip.emilianofusaglia.net/255.255.255.0
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add vip -node host06a -netnum 2 -address host06b-vip.emilianofusaglia.net/255.255.255.0

 

As grid user  create a new listener based on the network number 2:

grid@host01a:~# srvctl add listener -listener LISTENER2 -netnum 2 -endpoints "TCP:1532"

 

As root user add the new SCAN to the network number 2:

 root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl add scan -scanname scan-02.emilianofusaglia.net -netnum 2

 

As root user start the new node VIPs:

root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl start vip -vip host01b-vip.emilianofusaglia.net
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl start vip -vip host02b-vip.emilianofusaglia.net
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl start vip -vip host03b-vip.emilianofusaglia.net
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl start vip -vip host04b-vip.emilianofusaglia.net
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl start vip -vip host05b-vip.emilianofusaglia.net
root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl start vip -vip host06b-vip.emilianofusaglia.net

 

As grid user start the new node Listeners:

grid@host01a:~# srvctl start listener -listener LISTENER2
grid@host01a:~# srvctl status listener -listener LISTENER2
Listener LISTENER2 is enabled
Listener LISTENER2 is running on node(s): host01a,host02a,host03a,host04a,host05a,host06a

 

As root user start the new SCAN and as grid user check the configuration:

root@host01a:~# /u01/app/12.2.0.1/grid/bin/srvctl start scan -netnum 2

grid@host01a:~# srvctl config scan -netnum 2
SCAN name: scan-02.emilianofusaglia.net, Network: 2
Subnet IPv4: 10.15.69.0/255.255.255.0/, static
Subnet IPv6:

SCAN VIP is enabled.
SCAN VIP is individually enabled on nodes:
SCAN VIP is individually disabled on nodes:
SCAN 2 IPv4 VIP: 10.15.69.45

SCAN VIP scan2_net2 is enabled
SCAN VIP scan2_net2 is running on node host01a
SCAN VIP scan3_net2 is enabled
SCAN VIP scan3_net2 is running on node host03a

 

As grid user add the SCAN Listener and check the configuration:

grid@host01a:~# srvctl add scan_listener -netnum 2 -listener LISTENER2 -endpoints TCP:1532

grid@host01a:~# srvctl config scan_listener -netnum 2
SCAN Listener LISTENER2_SCAN1_NET2 exists. Port: TCP:1532

SCAN Listener LISTENER2_SCAN3_NET2 exists. Port: TCP:1532
Registration invited nodes:
Registration invited subnets:
SCAN Listener is enabled.
SCAN Listener is individually enabled on nodes:
SCAN Listener is individually disabled on nodes:

 

As grid user start the SCAN Listener2 and check the status:

grid@host01a:~# srvctl start scan_listener -netnum 2

grid@host01a:~# srvctl status scan_listener -netnum 2
SCAN Listener LISTENER2_SCAN1_NET2 is enabled
SCAN listener LISTENER2_SCAN1_NET2 is running on node host02a
SCAN Listener LISTENER2_SCAN2_NET2 is enabled
SCAN listener LISTENER2_SCAN2_NET2 is running on node host01a
SCAN Listener LISTENER2_SCAN3_NET2 is enabled
SCAN listener LISTENER2_SCAN3_NET2 is running on node host03a

 

Defining the multi SCANs configuration per database

Once the above configuration is completed, it remains to define which SCAN/s should be used by each database.

When multiple SCANs exists, by default the CRS populate the LISTENER_NETWORKS parameter to register the database against all SCANs and LISTENERs.

To overwrite this default behavior, allowing for example the authentication of a specific database only against the SCAN scan-02.emilianofusaglia.net, the database parameter LISTENER_NETWORKS should be manually configured.
The parameter LISTENER_NETWORKS can be dynamically set but the new value is enforced during the next instance restart.

 


 

ASM Filter Driver (ASMFD)

 

ASM Filter Driver is a Linux kernel module introduced in 12c R1. It resides in the I/O path of the Oracle ASM disks providing the following features:

  • Rejecting all non-Oracle I/O write requests to ASM Disks.
  • Device name persistency.
  • Node level fencing without reboot.

 

In 12c R2 ASMFD can be enabled from the GUI interface of the Grid Infrastructure installation, as shown on this post GI 12c R2 Installation at the step #8 “Create ASM Disk Group”.

Once ASM Filter Driver is in use, similarly to ASMLib the disks are managed using the ASMFD Label Name.

 

Here few examples about the implementation of ASM Filter Driver.

--How to create an ASMFD label in SQL*Plus
SQL> Alter system label set 'DATA1' to '/dev/mapper/mpathak';

System altered.


--How to create an ASM Disk Group with ASMFD
CREATE DISKGROUP DATA_DG EXTERNAL REDUNDANCY DISK 'AFD:DATA1' SIZE 30720M
ATTRIBUTE 'SECTOR_SIZE'='512','LOGICAL_SECTOR_SIZE'='512','compatible.asm'='12.2.0.1',
'compatible.rdbms'='12.2.0.1','compatible.advm'='12.2.0.1','au_size'='4M';

Diskgroup created.

 

ASM Filter Driver can also be managed from the ASM command line utility ASMCMD

--Check ASMFD status
ASMCMD> afd_state

Installing Oracle Grid Infrastructure 12c R2

It has been an exciting week, Oracle 12c R2 came out and suddenly was time to refresh the RAC test environments. My friend Jacques opted for an upgrade from 12.1.0.2 to 12.2.0.1 (here the link to his blog post),  I started with a fresh installation, because I also upgraded the Operating System to OEL  7.3.

Compared to 12c R1 there are new options on the installation process, but general speaking the wizard is quite similar.

The first breakthrough is about the installation simplified with an image based, no more runIstaller.sh to invoke but …

Unpack the .Zip file directly inside the Grid Infrastructure Home of the first cluster node as described below:

[grid@oel7node06 ~]$ mkdir -p /u01/app/12.2.0.1/grid 
[grid@oel7node06 ~]$ chown grid:oinstall /u01/app/12.2.0.1/grid 
[grid@oel7node06 ~]$ cd /u01/app/12.2.0.1/grid 
[grid@oel7node06 grid]$ unzip -q download_location/grid_home_image.zip

# From an X session invoke the Grid Infrastructure wizard: 
[grid@oel7node06 grid]$ ./gridSetup.sh

The second screenshot list the new Cluster typoligies available on 12c R2:

  • Oracle Standalone Cluster
  • Oracle Cluster Domain
    • Oracle Domain Services Cluster
    • Oracle Member Clusters
      • Oracle Member Cluster for Oracle Database
      • Oracle Member Cluster for Applications

 

In my case I’m installing an Oracle Standalone Cluster
