Announcing Oracle Database Service for Microsoft Azure

Today, at Microsoft Inspire, Satya Nadella, CEO of Microsoft, and Larry Ellison, Chairman and CTO of Oracle Corporation, announced the availability of the Oracle Database Service for Microsoft Azure. With this new fully managed service, Azure customers can easily provision, access, and operate enterprise-grade Oracle Database services in Oracle Cloud Infrastructure (OCI) with a familiar Azure-like experience. Users can seamlessly build Azure applications using the high-performance, high-availability, and automated management of Oracle Database services such as Autonomous Database running on OCI.

Offering customers choice with Azure and OCI multicloud capabilities

Thousands of customers trust Microsoft and Oracle for their enterprise applications, and many of them use the two sets of software and cloud products together. Since 2019, we have partnered to deliver the OCI-Azure Interconnect, which offers secure, private interconnections with sub-2 millisecond latency in 11 global regions and more regions on the way.

Microsoft and Oracle are extending this collaboration to further simplify the multicloud experience with the announcement of Oracle Database Service for Azure. Many of our joint customers, including some of the world’s largest corporations such as AT&T, GE, and FedEx, want their choice of services for the best performance, scalability, and availability to accelerate their transformation efforts. The Oracle Database Service for Azure builds upon the core capabilities of the OCI-Azure Interconnect and enables any customer to seamlessly integrate workloads on Microsoft Azure with Oracle Database services on OCI. Customers using the service also benefit from having no data egress or ingress charges when moving data between OCI and Azure.

An OCI managed service with familiar experience for Azure users

With the new Oracle Database Service for Azure, Azure teams can treat databases running on OCI like an Azure resource. In just a few clicks, users can connect their Azure subscriptions to their OCI tenancy. The service automatically configures everything required to link the two cloud environments and federates Azure active directory identities, making it seamless for Azure users to use the service. It also provides an Azure like user interface and API experience for provisioning and managing Oracle database services on OCI.

Once your databases are up and running, the service delivers OCI database metrics, events, and logs to Azure, alongside the rest of your Azure data for unified telemetry and monitoring.

In addition, the service also simplifies customer support with a collaborative support model to offer a seamless issue resolution process that can be initiated with either Microsoft or Oracle.

Oracle database enterprise-grade performance, reliability, and automation combined with Microsoft Azure

Applications running on Azure leverage the full capabilities of the underlying OCI Oracle database platforms, including high performance, scalability, and availability enabled by Oracle Real Application Clusters (RAC). For all OCI database services, the infrastructure is managed by Oracle, and you have automated database lifecycle management. Furthermore, when you use the fully automated Autonomous Database environment, all database monitoring, tuning, patching, and upgrades are done for you so you can focus on improving applications and growing the business.

Azure applications that use databases running on OCI’s Exadata Database Service and Autonomous Database use Exadata’s unique underlying optimizations to process more transactions per second than non-Exadata environments and return query results faster by using sub-19 microsecond internal SQL latency and 10s of millions of IOs per second. Analytical queries from Azure applications such as Power BI can now achieve extreme throughput at scale with 100s of gigabytes to terabytes per second of internal database scan and up to 30 petabytes of compressed database capacity.

OCI's Distributed Cloud

These innovations are part of our vision for OCI’s distributed cloud – a cloud that can deliver services wherever and however customers need them. In addition to this partnership with Microsoft Azure, OCI Dedicated Region and Cloud@Customer solutions deliver cloud services to customers in more than 60 countries, in addition to 39 public cloud regions in 21 countries, 11 launched in the last 9 months, plus multiple US National Security regions. All OCI Regions support a range of hybrid cloud and multicloud architectures with our management services.

We believe a distributed cloud is the way to address varying needs of our worldwide customers. We continue to work on additional capabilities for OCI’s distributed cloud. Stay tuned!

Space Management Enhancements in Oracle Database 21c

This article describes the space management enhancements in Oracle database 21c.

◉ SecureFiles Shrink

In previous releases we were only able to free up space from SecureFile lobs by moving them, which could take a considerable amount of time for a large lob segment.

alter table tab1 move lob(lob_column_name) store as (tablespace new_ts);

In Oracle 21c we can defragment lob segments without affecting access. This releases unused space, without the overhead of a full move of the LOB segment.

The shrink can be performed for the lob segments of a specific column, or as part of a cascade operation for a table.

alter table t1 modify lob (colb_column1) (shrink space);

alter table t1 shrink space cascade;

The cascade operation was valid in previous releases, but SecureFile LOB segments were not included in the cascade.

The V$SECUREFILE_SHRINK view contains a row for a shrink operation of a segment. It is updated during the operation, and is overwritten if another shrink operation is requested for the same segment.

If the LOB is shrunk directly, rather than as part of a cascading table shrink, row movement doesn't need to be enabled for the operation to complete, as shown below.

We create a table containing a LOB column, and populate it with 1000 rows,

create table t1 as 

  select level as id,

         to_clob(dbms_random.string('x',32767)) as clob_data

  from   dual

  connect by level <= 1000;

commit;

alter table t1 add constraint t1_pk primary key (id);

We check the lob segment statistics and we can see the number of blocks used to store the LOB.

select ul.table_name,

       ul.column_name,

       ul.segment_name,

       us.blocks

from   user_lobs ul

       join user_segments us on us.segment_name = ul.segment_name;

TABLE_NAME   COLUMN_NAME  SEGMENT_NAME   BLOCKS

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

T1       CLOB_DATA    SYS_LOB0000074741C00002$$       2088

1 row selected.

SQL>

We delete the majority of the rows from the table.

delete from t1 where id < 900;

commit;

When we check the lob segment statistics and we can see the number of blocks used to store the LOB segment hasn't changed.

exec dbms_stats.gather_table_stats(null, 'T1');

select ul.table_name,

       ul.column_name,

       ul.segment_name,

       us.blocks

from   user_lobs ul

       join user_segments us on us.segment_name = ul.segment_name;

TABLE_NAME   COLUMN_NAME  SEGMENT_NAME   BLOCKS

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

T1      CLOB_DATA    SYS_LOB0000074741C00002$$     2088

SQL>

We shrink the lob segment.

alter table t1 modify lob(clob_data) (shrink space);

When we check the lob segment statistics again we see the number of blocks used to store the LOB segment has reduced.

exec dbms_stats.gather_table_stats(null, 'T1');

select ul.table_name,

       ul.column_name,

       ul.segment_name,

       us.blocks

from   user_lobs ul

       join user_segments us on us.segment_name = ul.segment_name;

TABLE_NAME   COLUMN_NAME  SEGMENT_NAME   BLOCKS

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

T1       CLOB_DATA    SYS_LOB0000079689C00002$$    1184

SQL>

We can see row movement was not enabled on this table, yet the shrink of the SecureFile LOB segment worked anyway. Remember, the table rows are not being shrunk by this operation. Just the LOB segments.

select row_movement

from   user_tables

where  table_name = 'T1';

ROW_MOVE

--------

DISABLED

SQL>

In Oracle 19c the same shrink operation on a SecureFile LOB would give the following error.

alter table t1 modify lob(clob_data) (shrink space);

Error starting at line : 1 in command -

alter table t1 modify lob(clob_data) (shrink space)

Error report -

ORA-10635: Invalid segment or tablespace type

◉ Automatic Temporary Tablespace Shrink

As the name suggests, the Automatic Temporary Tablespace Shrink feature will shrink the size of the temporary tablespace to free up space. The database can pre-emptively grow the temporary tablespace if more is needed. The documentation refers to this as Automatic Temp Tablespace Sizing. That allows us to let the temporary tablespace expand and contract as needed, without a permanent loss of disk space.

At the time of writing the documentation is limited to the New Feature manual, which just says it exists with no details of usage control or logging.

Thanks to Roger MacNicol for pointing out the relevant statistics in the V$SYSSTAT view.

column name format a40

select con_id,

       name,

       value

from   v$sysstat

where  name like '%TBS%';

    CON_ID        NAME                               VALUE

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

         0 TBS Extension: tasks created                0

         0 TBS Extension: tasks executed              0

         0 TBS Extension: files extended               0

         0 TBS Extension: bytes extended              0

         0 TBS Shrink: tasks created                      0

         0 TBS Shrink: tasks executed                    0

SQL>

This feature was first introduced in Oracle 19c Autonomous Database, but from Oracle 21c it is available on-prem for enterprise edition installations.

◉ Automatic Undo Tablespace Shrink

As the name suggests, the Automatic Undo Tablespace Shrink feature will shrink the size of the undo tablespace to free up space. Expired undo segments are dropped, and if possible the data files are shrunk. That allows us to let the undo tablespace expand and contract as needed, without a permanent loss of disk space.

At the time of writing the documentation is limited to the New Feature manual (here), which just says it exists with no details of usage control or logging.

#dnf update -y

Create the new groups and users.

groupadd -g 54321 oinstall

groupadd -g 54322 dba

groupadd -g 54323 oper

#groupadd -g 54324 backupdba

#groupadd -g 54325 dgdba

#groupadd -g 54328 asmoper

#groupadd -g 54329 asmadmin

useradd -u 54321 -g oinstall -G dba,oper oracle

passwd oracle

We are not going to use the extra groups, but include them if you do plan on using them.

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1

mkdir -p /u02/oradata

chown -R oracle:oinstall /u01 /u02

chmod -R 775 /u01 /u02

Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS.

If you are using X Emulation, login as root and issue the following command.

xhost +<machine-name>

You will need to add the following symbolic links or the Oracle Universal Installer (OUI) will not start.

# Fix for Oracle on Fedora.

rm -f /usr/lib64/libnsl.so.1

rm -f /usr/lib/libnsl.so.1

ln -s /usr/lib64/libnsl.so.3.0.0 /usr/lib64/libnsl.so.1

ln -s /usr/lib/libnsl.so.3.0.0 /usr/lib/libnsl.so.1

Set up the environment for the "oracle" user. The "$" characters are escaped using "\". If you are not creating the file with the cat command, you will need to remove the escape characters.

mkdir -p /home/oracle/scripts

cat > /home/oracle/scripts/setEnv.sh <<EOF

        1. /u01/app/oraInvenotry/orainstRoot.sh

        2. /u01/app/oracle/product/19.0.0/dbhome_1/root.sh

You are now ready to create a database.

◉ Database Creation

You create a database using the Database Configuration Assistant (DBCA). The interactive mode will display GUI screens to allow user input, while the silent mode will create the database without displaying any screens, as all required options are already specified on the command line.

We are not going to use the extra groups, but include them if you do plan on using them.

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1

mkdir -p /u02/oradata

chown -R oracle:oinstall /u01 /u02

chmod -R 775 /u01 /u02

Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS.

If you are using X Emulation, login as root and issue the following command.

xhost +<machine-name>

You will need to add the following symbolic links or the Oracle Universal Installer (OUI) will not start.

# Fix for Oracle on Fedora.

rm -f /usr/lib64/libnsl.so.1

rm -f /usr/lib/libnsl.so.1

ln -s /usr/lib64/libnsl.so.2.0.1 /usr/lib64/libnsl.so.1

ln -s /usr/lib/libnsl.so.2.0.1 /usr/lib/libnsl.so.1

Set up the environment for the "oracle" user. The "$" characters are escaped using "\". If you are not creating the file with the cat command, you will need to remove the escape characters.

You are now ready to create a database.

➤ Database Creation

You create a database using the Database Configuration Assistant (DBCA). The interactive mode will display GUI screens to allow user input, while the silent mode will create the database without displaying any screens, as all required options are already specified on the command line.

Oracle Database 19c Installation On Fedora 34 (F34)

This article describes the installation of Oracle Database 19c 64-bit on Fedora 34 (F34) 64-bit. The article is based on a server installation with a minimum of 2G swap and secure Linux set to permissive.

◉ Download Software

Download the Oracle software from OTN or MOS depending on your support status.

OTN: Oracle Database 19c (19.3) Software (64-bit).

edelivery: Oracle Database 19c (19.3) Software (64-bit)

◉ Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

For example.

127.0.0.1       localhost localhost.localdomain localhost4 localhost4.localdomain4

192.168.56.141  fedora34.localdomain  fedora34

Set the correct hostname in the "/etc/hostname" file.

fedora34.localdomain

◉ Set Kernel Parameters

Add the following lines to the "/etc/sysctl.conf" file, or in a file called "/etc/sysctl.d/98-oracle.conf".

fs.file-max = 6815744

kernel.sem = 250 32000 100 128

kernel.shmmni = 4096

kernel.shmall = 1073741824

kernel.shmmax = 4398046511104

kernel.panic_on_oops = 1

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

net.ipv4.conf.all.rp_filter = 2

net.ipv4.conf.default.rp_filter = 2

fs.aio-max-nr = 1048576

net.ipv4.ip_local_port_range = 9000 65500

Run one of the following commands to change the current kernel parameters, depending on which file you edited.

/sbin/sysctl -p

# Or

/sbin/sysctl -p /etc/sysctl.d/98-oracle.conf

Add the following lines to a file called "/etc/security/limits.d/oracle-database-server-19c-preinstall.conf" file.

oracle   soft   nofile    1024

oracle   hard   nofile    65536

oracle   soft   nproc    16384

oracle   hard   nproc    16384

oracle   soft   stack    10240

oracle   hard   stack    32768

oracle   hard   memlock    134217728

oracle   soft   memlock    134217728

Stop and disable the firewall. You can configure it later if you wish.

# systemctl stop firewalld

# systemctl disable firewalld

Set SELinux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=permissive

The server will need a reboot for the change to take effect.

#dnf update -y

Thanks to Nikolay Popov and Amadis for the suggestion of downgrading binutils to fix database creation with the DBCA.

Create the new groups and users.

groupadd -g 54321 oinstall

groupadd -g 54322 dba

chmod -R 775 /u01 /u02

Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS.

If you are using X Emulation, login as root and issue the following command.

xhost +<machine-name>

You will need to add the following symbolic links or the Oracle Universal Installer (OUI) will not start.

# Fix for Oracle on Fedora.

rm -f /usr/lib64/libnsl.so.1

rm -f /usr/lib/libnsl.so.1

Stop and disable the firewall. You can configure it later if you wish.

# systemctl stop firewalld

# systemctl disable firewalld

Set SELinux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=permissive

The server will need a reboot for the change to take effect.

#dnf update -y

Thanks to Nikolay Popov and Amadis for the suggestion of downgrading binutils to fix database creation with the DBCA.

Create the new groups and users.

groupadd -g 54321 oinstall

groupadd -g 54322 dba

groupadd -g 54323 oper

#groupadd -g 54324 backupdba

#groupadd -g 54325 dgdba

#groupadd -g 54326 kmdba

#groupadd -g 54328 asmdba

#groupadd -g 54328 asmoper

#groupadd -g 54329 asmadmin

useradd -u 54321 -g oinstall -G dba,oper oracle

passwd oracle

We are not going to use the extra groups, but include them if you do plan on using them.

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1

mkdir -p /u02/oradata

chown -R oracle:oinstall /u01 /u02

chmod -R 775 /u01 /u02

Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS.

If you are using X Emulation, login as root and issue the following command.

xhost +<machine-name>

You will need to add the following symbolic links or the Oracle Universal Installer (OUI) will not start.

# Fix for Oracle on Fedora.

rm -f /usr/lib64/libnsl.so.1

rm -f /usr/lib/libnsl.so.1

ln -s /usr/lib64/libnsl.so.2.0.0 /usr/lib64/libnsl.so.1

ln -s /usr/lib/libnsl.so.2.0.0 /usr/lib/libnsl.so.1

Set up the environment for the "oracle" user. The "$" characters are escaped using "\". If you are not creating the file with the cat command, you will need to remove the escape characters.

mkdir -p /home/oracle/scripts

cat > /home/oracle/scripts/setEnv.sh <<EOF

◉ Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

DISPLAY=<machine-name>:0.0; export DISPLAY

Perform a software-only installation either using interactive mode (GUI) or silent mode and run the root scripts when prompted. Notice the setting of the CV_ASSUME_DISTID environment variable, so fake the OS.

# Unzip software.

cd $ORACLE_HOME

unzip -oq /path/to/software/LINUX.X64_193000_db_home.zip

# Fake OS.

export CV_ASSUME_DISTID=OEL7.6

# Interactive mode.

#./runInstaller

# Silent mode.

Run the root scripts when prompted.

As a root user, execute the following script(s):

        1. /u01/app/oraInvenotry/orainstRoot.sh

        2. /u01/app/oracle/product/19.0.0/dbhome_1/root.sh

You are now ready to create a database.

◉ Database Creation

You create a database using the Database Configuration Assistant (DBCA). The interactive mode will display GUI screens to allow user input, while the silent mode will create the database without displaying any screens, as all required options are already specified on the command line.

# Start the listener.

lsnrctl start

# Interactive mode.

# dbca

# Silent mode.
