Summary of the policy's main properties
Default values for the policy: parameters with their default values and objects excluded by default
Impact of the policy violation
Action to perform when the violation occurs

The Database Instance policies are categorized as follows:

Section 4.1, "Configuration Policies"
Section 4.2, "Security Policies - UNIX"
Section 4.3, "Security Policies - Windows"
Section 4.4, "Storage Policies"

4.1 Configuration Policies

The configuration policies for the Database Instance target are:

4.1.1 Disabled Automatic Statistics Collection

This policy checks if the STATISTICS_LEVEL initialization parameter is set to BASIC.

The STATISTICS_LEVEL initialization parameter has three valid settings, TYPICAL, ALL, and BASIC.

The default setting of TYPICAL ensures collection of all major statistics required for database self-management and functionality and provides best overall performance. The default value should be adequate for most environments.
Setting the parameter to ALL collects all the same statistics that are collected with the TYPICAL setting, plus timed OS and plan execution statistics.
Setting the parameter to BASIC disables the collection of many important statistics that are required by Oracle Database features and functionality.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Critical	Configuration	Database Instance	Oracle Server 10g Release	The underlying metric has a collection frequency of once every 24 hours.	Yes	Your database is set to BASIC. Many important statistics required by Oracle database features and functionality are disabled.

^Footnote 1The policy rule is evaluated each time its underlying db_init_params metric is collected.

Defaults

Parameters and Their Default Values

STATISTICS_LEVEL: TYPICAL

Objects Excluded by Default

Not Applicable

Impact of Violation

Automatic statistics collection allows the optimizer to generate accurate execution plans and is essential for identifying and correcting performance problems. By default, STATISTICS_LEVEL is set to TYPICAL. If the STATISTICS_LEVEL initialization parameter is set to BASIC, the collection of many important statistics, required by Oracle database features and functionality, are disabled.

Action

Set the STATISTICS_LEVEL initialization parameter to TYPICAL.

4.1.2 Force Logging Disabled

When Data Guard Broker is being used, this policy checks the primary database for disabled force logging.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Configuration	Database Instance; Cluster Database	Oracle Server 9i Release 2 or later	The underlying metrics have a collection frequency of once every 24 hours.	Yes	The primary database is not in force logging mode. As a result, unlogged direct writes in the primary database cannot be propagated to the standby database.

^Footnote 1The policy rule is evaluated each time its underlying db_init_params and ha_info metrics are collected.

Defaults

Parameters and Their Default Values

Not Applicable

Objects Excluded by Default

Not Applicable

Impact of Violation

The primary database is not in force logging mode. As a result, unlogged direct writes in the primary database cannot be propagated to the standby database.

Action

The primary database should be put in force logging mode using the ALTER DATABASE FORCE LOGGING parameter.

4.1.3 Insufficient Number of Control Files

This policy checks for use of a single control file.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Critical	Configuration	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	Your database has insufficient control files. If you lose the only copy of the control file due to a media error, there will be unnecessary down time and other risks.

^Footnote 1The policy rule is evaluated each time its underlying db_controlfiles metric are collected.

Defaults

Parameters and Their Default Values

Parameter default values are dependent on the version of the Oracle Database target. Refer to the Oracle Database documentation for that version of the database target to learn about the parameters and their default values.

Objects Excluded by Default

Not Applicable

Impact of Violation

The control file is one of the most important files in an Oracle database. It maintains many physical characteristics and important recovery information about the database. If you lose the only copy of the control file due to a media error, there will be unnecessary down time and other risks.

Action

Use at least two control files that are multiplexed on different disks.

4.1.4 Insufficient Number of Redo Logs

This policy checks for use of less than three redo logs.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Warning	Configuration	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	Your database has insufficient number of redo log files. When the size and number of online redo logs are inadequate, LGWR will wait for ARCH to complete its writing to the archived log destination, before it overwrites that log. This can cause severe performance slowdowns during peak activity periods.

^Footnote 1The policy rule is evaluated each time its underlying db_redoLogs metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Not Applicable

Impact of Violation

The online redo log files are used to record changes in the database for the purposes of recoverability. When archiving is enabled, these online redo logs need to be archived before they can be reused. Every database requires at least two online redo log groups to be up and running. When the size and number of online redo logs are inadequate, LGWR will wait for ARCH to complete its writing to the archived log destination, before it overwrites that log. This can cause severe performance slowdowns during peak activity periods.

Action

Oracle recommends having at least three online redo log groups with at least two members in each group. For obvious reasons, members of the same group must be on different disk drives.

4.1.5 Not Using Automatic PGA Management

This policy checks if the PGA_AGGREGATE_TARGET initialization parameter has a value of 0 or if WORKAREA_SIZE_POLICY has value of MANUAL.

This parameter automatically controls the amount of memory allocated for sorts and hash joins. Larger amounts of memory allocated for sorts or hash joins reduce the optimizer cost of these operations.

For OLTP systems, the PGA memory typically accounts for a small fraction of the total memory available (for example, 20%), leaving 80% for the SGA.
For DSS systems running large, memory-intensive queries, PGA memory can typically use up to 70% of that total (up to 2.2 GB in this example).

Good initial values for the parameter PGA_AGGREGATE_TARGET might be:

For OLTP: PGA_AGGREGATE_TARGET = (total_mem * 80%) * 20%
For DSS: PGA_AGGREGATE_TARGET = (total_mem * 80%) * 50% where total_mem is the total amount of physical memory available on the system.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Warning	Configuration	Database Instance	Oracle Server 9i or later	The underlying metric has a collection frequency of once every 24 hours.	Yes	Your database is not using Automatic PGA memory management. It simplifies and improves the way PGA memory is allocated.

^Footnote 1The policy rule is evaluated each time its underlying db_init_params metric is collected.

Defaults

Parameters and Their Default Values

PGA_AGGREGATE_TARGET: 0

WORKAREA_SIZE_POLICY: MANUAL

Objects Excluded by Default

Not Applicable

Impact of Violation

Automatic PGA memory management simplifies and improves the way PGA memory is allocated. When enabled, Oracle can dynamically adjust the portion of the PGA memory dedicated to work areas while honoring the PGA_AGGREGATE_TARGET limit set by the DBA.

Action

Enable Automatic PGA Memory Management and set the PGA_AGGREGATE_TARGET initialization parameter to a non-zero number. Use Oracle PGA advice to help set PGA_AGGREGATE_TARGET to the best size.

4.1.6 Not Using Automatic Undo Management

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Critical	Configuration	Database Instance	Oracle Server 9.2 or later	The underlying metric has a collection frequency of once every 24 hours.	Yes	Your database is not using automatic undo management. This can cause unnecessary contention and performance issues.

^Footnote 1The policy rule is evaluated each time its underlying db_init_params metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

None

Impact of Violation

Not using automatic undo management can cause unnecessary contention and performance issues in your database. This may include among other issues, contention for the rollback segment header blocks, in the form of buffer busy waits and increased probability of ORA-1555s (Snapshot Too Old).

Action

Use automatic undo space management instead of manual undo or rollback segments.

4.1.7 Not Using Spfile

This policy checks for spfile not being used.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Critical	Configuration	Database Instance	Oracle Server 9i or later	The underlying metric has a collection frequency of once every 24 hours.	Yes	Your database is not using spfile. The changes made using ALTER SYSTEM commands will not persist.

^Footnote 1The policy rule is evaluated each time its underlying db_init_params metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Not Applicable

Impact of Violation

The SPFILE (server parameter file) enables you to persist any dynamic changes to the Oracle initialization parameters using ALTER SYSTEM commands. This persistence is provided across database shutdowns. When a database has an SPFILE configured, you do not have to remember to make the corresponding changes to the Oracle initialization file. In addition, any changes that are made using the ALTER SYSTEM commands are not lost after a shutdown and restart.

Action

Use the server side parameter file to update changes dynamically.

4.1.8 Recovery Area Location Not Set

4.4 Storage Policies

The storage policies for the Database Instance target are:

4.4.1 Default Permanent Tablespace Set to a System Tablespace

This policy verifies that the DEFAULT_PERMANENT_TABLESPACE database property is set to a non-system tablespace. The default permanent tablespace for the database is used as the default permanent tablespace for any users who are not explicitly assigned a permanent tablespace. The default permanent tablespace is defaulted to the SYSTEM tablespace until it is changed by a DBA.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Warning	Storage	Database Instance; Cluster Database	Oracle Server 10g Release 1 or later	The underlying metric has a collection frequency of once every 24 hours.	Yes	The default permanent tablespace is not set explicitly and defaults to SYSTEM tablespace.

^Footnote 1The policy rule is evaluated each time its underlying db_recTablespaceSettings metric is collected.

Defaults

Parameters and Their Default Values

SYSTEM

Objects Excluded by Default

Not Applicable

Impact of Violation

If not specified explicitly, the DEFAULT_PERMANENT_TABLESPACE is defaulted to the SYSTEM tablespace. This is not the recommended setting. The default permanent tablespace for the database is used as the permanent tablespace for any non-SYSTEM users who are not explicitly assigned a permanent tablespace. If the database default permanent tablespace is set to a system tablespace, then any user who is not explicitly assigned a tablespace uses the system tablespace. Non-SYSTEM users should not be using a system tablespaces to store data. Doing so may result in performance degradation for the database.

Action

Set the DEFAULT_PERMANENT_TABLESPACE to a non-system tablespace. Create or edit a tablespace and set it to be the default permanent tablespace.

Clicking the DEFAULT_PERMANENT_TABLESPACE link will bring up the Tablespace Search page. From this page you can create or edit a tablespace and set it to be the default permanent tablespace.

On the Administration property page for the database instance, click Tablespaces under the Storage options. After providing your credentials, create or edit a permanent tablespace and set it to be the default permanent tablespace.

4.4.2 Default Temporary Tablespace Set to a System Tablespace

This policy verifies that the DEFAULT_TEMP_TABLESPACE database property is set to a non-system tablespace. The default temporary tablespace for the database is used as the temporary tablespace for any users that are not explicitly assigned a temporary tablespace. The temporary tablespace is defaulted to the SYSTEM tablespace until it is changed by a DBA.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Warning	Storage	Database Instance; Cluster Database	Oracle Server 9i or later	The underlying metric has a collection frequency of once every 24 hours.	Yes	The default temporary tablespace is not set explicitly and defaults to SYSTEM tablespace.

^Footnote 1The policy rule is evaluated each time its underlying db_recTablespaceSettings metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Not Applicable

Impact of Violation

If not specified explicitly, the DEFAULT_TEMP_TABLESPACE defaults to the SYSTEM tablespace. This is not the recommended setting. The default temporary tablespace is used as the temporary tablespace for any users who are not explicitly assigned a temporary tablespace. If the database default temporary tablespace is set to a system tablespace, then any user who is not explicitly assigned a temporary tablespace uses the system tablespace as their temporary tablespace. System tablespaces should not be used to store temporary data. Doing so can result in performance degradation for the database.

Action

Set the DEFAULT_TEMP_TABLESPACE to a non-system temporary tablespace. In Oracle Database 10g Release 1 or later, you can also set the DEFAULT_TEMP_TABLESPACE to a temporary tablespace group. Create or edit a temporary tablespace, or temporary tablespace group, and set it to be the default temporary tablespace.

Clicking the DEFAULT_TEMP_TABLESPACE link will bring up the Tablespace Search page. From this page the user can create or edit a temporary tablespace and set it to be the default temporary tablespace.

On the Administration property page for the database instance, click Tablespaces under the Storage options. After providing your credentials, create or edit a temporary tablespace and set it to be the default temporary tablespace.

4.4.3 Dictionary Managed Tablespaces

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Critical	Storage	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	Your database has redo log that has insufficient size.

^Footnote 1The policy rule is evaluated each time its underlying db_redo_logs metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Not Applicable

Impact of Violation

Small redo logs cause system checkpoints to continuously put a high load on the buffer cache and I/O system.

Action

Increase size of the redo logs to at least 1 MB.

4.4.5 Non-System Data Segments in a System Tablespace

Redefine the tablespaces containing the segments to be locally managed; or, reorganize these segments, specifying a Next Extent value that is a multiple of Initial Extent, and a Percent Increase value of 0.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Storage	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	Segment %OBJECT% belonging to non-system users are stored in system tablespace %TABLESPACE_NAME%. This makes it more difficult to manage these data segments and may result in performance degradation in the system tablespace.

^Footnote 1The policy rule is evaluated each time its underlying db_recSegmentSettings metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Cluster object types because the Reorganize Objects wizard does not support them.

All user accounts that are, by default, part of the Oracle Database or Enterprise Manager. For example: SYS, SYSTEM, SYSMAN, CTXSYS, SCOTT, ADAMS, and so on.

Impact of Violation

These segments belonging to non-system users are stored in system tablespaces SYSTEM or SYSAUX. This violation makes it more difficult to manage these data segments and may result in performance degradation in the system tablespace. System users include users that are part of the DBMS such as SYS and SYSTEM, or that are part of Oracle-supplied facilities: for example, CTXSYS, SYSMAN, and OLAPSYS.

Action

Relocate the non-system segments to a non-system tablespace.

4.4.6 Non-System Users with System Tablespace as Default Tablespace

This policy, using the SYSTEM_AS_DEFAULT_TBSP parameter, checks for any user having a System tablespace listed as their default tablespace.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Storage	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	User %USER_NAME% uses SYSTEM tablespace as the default tablespace. This will result in non-system data segments being added to the SYSTEM tablespace and possible performance degradation in the SYSTEM tablespace..

^Footnote 1The policy rule is evaluated each time its underlying db_recUserSettings metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Cluster object types because the Reorganize Objects wizard does not support them.

All user accounts that are, by default, part of the Oracle Database or Enterprise Manager. For example: SYS, SYSTEM, SYSMAN, CTXSYS, SCOTT, ADAMS, and so on.

Impact of Violation

These users use a system tablespace as the default tablespace. This violation will result in non-system data segments being added to the system tablespace, making it more difficult to manage these data segments and possibly resulting in performance degradation in the system tablespace.

Action

Change the default tablespace for these users to specify a non-system tablespace.

4.4.7 Non-Uniform Default Extent Size for Tablespaces

This policy checks for tablespaces with non-uniform default extent size.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Storage	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	Tablespace %TABLESPACE_NAME% uses non-uniform extents. Using uniform extents ensures that any free extent in the tablespace can always be used for any segment in the tablespace.

^Footnote 1The policy rule is evaluated each time its underlying db_tablespaces metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

SYSTEM tablespace. This policy is only applicable to PERMANENT DICTIONARY tablespaces.

Impact of Violation

Tablespaces using a non-uniform default extent size exist. Extents in a tablespace should be the same size. This ensures that any free extent in the tablespace can always be used for any segment in the tablespace.

Action

To ensure uniform extent sizes, set each tablespace's default storage clause so that the NEXT value should be equal to or a multiple of the INITIAL value, and the PCTINCREASE value is set to zero. Then never explicitly specify a storage clause at the segment level. Instead, let the storage values for the segments be inherited from the default storage clause of the tablespace.

4.4.8 Rollback in SYSTEM Tablespace

Rollback in SYSTEM Tablespace.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Storage	Database Instance; Cluster Database	All	See following table	Yes	Your SYSTEM tablespace contains rollback segment %RBS_NAME%. The SYSTEM tablespace should be reserved only for the Oracle data dictionary and its associated objects.

^Footnote 1The policy rule is evaluated each time its underlying metric is collected.

The following table lists the policy's underlying metrics.

Underlying Metric	Collection Frequency
db_init_params	Every 24 hours
db_rollback_segs	Every 24 hours

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Not Applicable

Impact of Violation

The SYSTEM tablespace should be reserved only for the Oracle data dictionary and its associated objects. It should NOT be used to store any other types of objects such as user tables, user indexes, user views, rollback segments, undo segments, or temporary segments.

Action

Use a tablespace dedicated to undo instead of the SYSTEM tablespace.

4.4.9 Segment with Extent Growth Policy Violation

This policy, using the SEG_EXT_GROWTH_VIO parameter, checks for segments in dictionary managed tablespaces having irregular extent sizes and/or non-zero Percent Increase settings.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Storage	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	Segment %OBJECT% in dictionary managed tablespace %TABLESPACE_NAME% has irregular extent sizes and/or non-zero Percent Increase settings. This can result in inefficient reuse of space and fragmentation problems.

^Footnote 1The policy rule is evaluated each time its underlying db_recSegmentSettings metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Not Applicable

Impact of Violation

These segments have extents with sizes that are not multiples of the initial extent, and/or a non-zero Percent Increase setting. This can result in inefficient reuse of space and fragmentation problems.

Action

4.4.10 Tablespace Not Using Automatic Segment-Space Management

This policy checks for locally managed tablespaces that are using MANUAL segment space management.

There are two segment-space management settings, MANUAL and AUTO.

MANUAL segment-space management uses free lists to manage free space within segments. Free lists are lists of data blocks that have space available for inserting rows. With this form of segment-space management, you must specify and tune the PCTUSED, FREELISTS and FREELIST GROUPS storage parameters for schema objects created in the tablespace.
AUTO segment-space management uses bitmaps to manage the free space in segments. The bitmap describes the status of each data block within a segment with respect to the amount of space in the block available for inserting rows. These bitmaps allow the database to manage free space automatically.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Storage	Database Instance; Cluster Database	Oracle Server 9.2 or later	The underlying metric has a collection frequency of once every 24 hours.	Yes	Tablespace %TABLESPACE_NAME% is not using automatic segment-space management.

^Footnote 1The policy rule is evaluated each time its underlying db_recTablespaceSettings metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

Not Applicable

Impact of Violation

Automatic segment-space management is a simpler and more efficient way of managing space within a segment. It completely eliminates any need to specify and tune the PCTUSED, FREELISTS and FREELIST GROUPS storage parameters for schema objects created in the tablespace.

In a RAC environment, there is the additional benefit of avoiding the hard partitioning of space inherent with using free list groups.

Action

Change the segment-space management of all permanent locally managed tablespaces to AUTO.

Clicking the name of each tablespace listed will bring up the Reorganize Objects wizard with the tablespace automatically selected. This wizard allows you to change the segment-space management of the tablespace from MANUAL to AUTO.

4.4.11 Tablespaces Containing Rollback and Data Segments

This policy, using the TBSP_MIXED_SEGS parameter, checks for tablespaces containing both rollback and data segments.

Policy Summary

The following table lists the policy's main properties.

Severity	Category	Target Type	Versions Affected	Policy Rule Evaluation^Foot 1	Automatically Enabled?	Alert Message
Informational	Storage	Database Instance; Cluster Database	All	The underlying metric has a collection frequency of once every 24 hours.	Yes	Tablespace %TABLESPACE_NAME% contains both rollback and data segments. Mixing segment types in this way makes it more difficult to manage space and may degrade performance in the tablespace.

^Footnote 1The policy rule is evaluated each time its underlying db_recTablespaceSettings metric is collected.

Defaults

Parameters and Their Default Values

Objects Excluded by Default

SYSTEM tablespace

Impact of Violation

These tablespaces contain both rollback and data segments. Mixing segment types in this way makes it more difficult to manage space and may degrade performance in the tablespace. Use of a dedicated tablespace for rollback segments enhances availability and performance.

Action

Use Automatic Undo Management (in Oracle Server Release 9.0.1 or later) and perform one of the following:

Drop the rollback segments from this tablespace.
Create one or more tablespaces dedicated to rollback segments and drop the rollback segments from this tablespace.
Dedicate this tablespace to rollback segments and move the data segments to another tablespace.

4.4.12 Users with Permanent Tablespace as Temporary Tablespace

This policy checks the PERM_AS_TEMP_TBSP parameter to detect whether a permanent tablespace is being used as a temporary tablespace.

Policy Summary
