E CRSCTL Utility Reference

This appendix describes how to administer Oracle Clusterware using the Oracle Clusterware Control (CRSCTL) utility.

Note:

Do not use CRSCTL commands on Oracle entities (such as resources, resource types, and server pools) that have names beginning with ora unless you are directed to do so by My Oracle Support. The Server Control utility (SRVCTL) is the correct utility to use on Oracle entities.

This appendix includes the following topics:


CRSCTL Overview

CRSCTL is an interface between you and Oracle Clusterware, parsing and calling Oracle Clusterware APIs for Oracle Clusterware objects.

Oracle Clusterware 11g release 2 (11.2) introduces cluster-aware commands with which you can perform check, start, and stop operations on the cluster. You can run these commands from any node in the cluster on another node in the cluster, or on all nodes in the cluster, depending on the operation.

You can use CRSCTL commands to perform several operations on Oracle Clusterware, such as:


Clusterized (Cluster Aware) Commands

You can run clusterized commands on one node to perform operations on another node in the cluster. These are referred to as remote operations. This simplifies administration because, for example, you no longer have to log in to each node to check the status of the Oracle Clusterware on all of your nodes.

Clusterized commands are completely operating system independent; they rely on the OHASD (Oracle High Availability Services daemon). If this daemon is running, then you can perform remote operations, such as the starting, stopping, and checking the status of remote nodes.

Clusterized commands include the following:


Operational Notes

Usage Information

Using CRSCTL Help

To print the help information for CRSCTL, use the following command:

crsctl -help

If you want help for a specific command, such as start, then enter the command and append -help to the end, as shown in the following example:

crsctl start -help

You can also use the abbreviations -h or -? (this option functions in Linux, UNIX, and Windows environments) instead of -help.


Deprecated Subprograms or Commands

The following commands are deprecated in Oracle Clusterware 11g release 2 (11.2):


CRSCTL Command Reference

This section is separated into three categories of CRSCTL commands:


Dual Environment CRSCTL Commands

You can use the following commands in either the Oracle RAC or the Oracle Restart environments:

crsctl add resource

Use the crsctl add resource command to register a resource to be managed by Oracle Clusterware. A resource could be an application process, a database, a service, a listener, and so on.

Syntax

crsctl add resource resource_name -type resource_type [-file file_path |
-attr "attribute_name=attribute_value,attribute_name=attribute_value,..."]
[-i] [-f]

Parameters

Table E-1 crsctl add resource Command Parameters

Parameter Description
resource_name

A short, descriptive name for the resource.

-type resource_type

The type of resource that you are adding preceded by the -type flag.

-file file_path

Path name (either absolute or relative) for a text file containing line-separated attribute name-value pairs that define the resource.

-attr "attribute_name=
attribute_value

You can specify attributes for a resource you are adding in two different ways:

  • Following the -attr flag, you can specify one or more comma-delimited attribute name-value pairs enclosed in double quotations marks (""). For example:

    -attr "CHECK_INTERVAL=30,START_TIMEOUT=25"
    
  • Additionally, you can specify attribute values for resource instances with a particular cardinality value, and with a particular degree value. This method can be useful for applications that are tied to a particular server. Following the -attr flag, the syntax is as follows:

    attribute_name{@SERVERNAME(server_name)
    [@DEGREEID(did)] | @CARDINALITYID(cid)
    [@DEGREEID(did)]}=attribute_value
    

    If you specify the @SERVERNAME(server_name) syntax, then the attribute value you specify for the attribute you specify is limited to resource instances residing on the server you specify.

    Alternatively, if you specify the @CARDINALITYID(cid) syntax, then the attribute value you specify for the attribute you specify is limited to resource instances with a specific cardinality ID (cid).

    Optionally, you can combine the @DEGREEID(did) syntax with either the SERVERNAME or CARDINALITYID syntax, or both, to limit the attribute value to resources with the specific DEGREE.

    Examples:

    CHECK_INTERVAL@SERVERNAME(node1)=45
    STOP_TIMEOUT@CARDINALITYID(2)=65
    STOP_TIMEOUT@SERVERNAME(node1)@DEGREEID(2)=65
    STOP_TIMEOUT@CARDINALITYID(3)@DEGREEID(2)=65
    
-i

If you specify -i, then the command returns an error if processing this command requires waiting for Oracle Clusterware to unlock the resource or its dependents. Sometimes, Oracle Clusterware locks resources or other objects to prevent commands from interfering with each other.

-f

Use the force option:

  • To add a resource that has dependencies on other resources that do not yet exist. The force option overrides checks that would prevent a command from being completed.

  • To add a resource if the resource has hard dependencies on other resources and the owner of the resources does not execute permissions on one or more of the dependencies. If you do not specify the force option in this case, an error displays.

  • To add resources of application type because you may need to move servers into the Generic server pool. If the servers currently host resources that must be stopped, then the force option is required


See Also:

Appendix B, "Oracle Clusterware Resource Reference" for more information about resources and resource attributes

Usage Notes

Example

Example 1

To register a VIP as a resource with Oracle Clusterware:

$ crsctl add resource app.appvip -type app.appvip.type -attr "RESTART_ATTEMPTS=2,
START_TIMEOUT=100,STOP_TIMEOUT=100,CHECK_INTERVAL=10,
USR_ORA_VIP=172.16.0.0,
START_DEPENDENCIES=hard(ora.net1.network)pullup(ora.net1.network),
STOP_DEPENDENCIES=hard(ora.net1.network)"

Example 2

To register a resources based on the test_type1 resource type:

$ crsctl add resource r1 -type test_type1 -attr "PATH_NAME=/tmp/r1.txt"
$ crsctl add resource r1 -type test_type1 -attr "PATH_NAME=/tmp/r2.txt"

crsctl add type

Use the crsctl add type command to create a resource type in Oracle Clusterware.

Syntax

crsctl add type type_name -basetype base_type_name {-attr
"ATTRIBUTE=attribute_name | -file file_path,TYPE={string | int}
 [,DEFAULT_VALUE=default_value][,FLAGS=[READONLY][|REQUIRED]]”}

Parameters

Table E-2 crsctl add type Command Parameters

Parameter Description
type_name

A name for the resource type in the form of xxx.yyy.type. Resource type names must be unique and cannot be changed after the resource type is registered.

-basetype base_type_name

The name of an existing base type. Any resource type that you create must either have local_resource or cluster_resource as its base resource type.

-attr

You can specify the resource type attributes using the -attr argument. Each type attribute definition can contain up to four type attribute keywords that must be displayed in the order shown. Enter a comma-delimited description of one or more resource type attributes enclosed in double quotation marks (""). The keywords for an attribute include:

  1. ATTRIBUTE: Specify a name for the attribute. The name is case-sensitive and cannot contain spaces.

  2. TYPE: Specify whether the attribute type is integer or string.

  3. DEFAULT_VALUE: (Optional) If the attribute is required, then a default value is not required. For attributes that are not required, you must specify a default value that Oracle Clusterware uses when you create resources based on this resource type.

  4. FLAGS: (Optional) Specify whether the attribute is READONLY or REQUIRED. READONLY means that after you register a resource with this resource type, you cannot modify this attribute.

    REQUIRED means that you must specify the name and value of this attribute when you create a resource that is based on this resource type. If you specify that this attribute is not required, then Oracle Clusterware uses the default value of this attribute that you specify.

You cannot use multiple -attr arguments to define multiple arguments for the resource type. Instead, you can specify multiple types within the double quotation marks after the -attr flag. For example:

"ATTRIBUTE=FOO,TYPE=integer,DEFAULT_
VALUE=0,FLAGS=REQUIRED,ATTRIBUTE=BAR,TYPE=string"

The preceding example defines two type attributes, FOO and BAR. When you specify the ATTRIBUTE keyword, it ends the previous type attribute (if any) and begins a new type attribute.

-file file_path

Path name (either absolute or relative) for a text file containing line-separated resource type keyword-value pairs that define the resource type. An example of the contents of the file is:

ATTRIBUTE=FOO
TYPE=integer
DEFAULT_VALUE=0
FLAGS=REQUIRED
ATTRIBUTE=BAR
TYPE=string

Note: The keywords must be in the following order: ATTRIBUTE, TYPE, DEFAULT_VALUE, and FLAGS. When you specify the ATTRIBUTE keyword, it ends the previous type attribute (if any) and begins a new type attribute.

The preceding example defines two type attributes, FOO and BAR.

"Resource Type" for more information about resource types

Usage Notes

Example

To create a resource type for demoActionScript:

# crsctl add type test_type1 -basetype cluster_resource 
 -attr "ATTRIBUTE=FOO,TYPE=integer,DEFAULT_VALUE=0"

crsctl check css

Use the crsctl check css command to check the status of Cluster Synchronization Services. This command is most often used when Oracle Automatic Storage Management (Oracle ASM) is installed on the local server.

Syntax

crsctl check css

Usage Notes

Example

Parameters

Table E-3 crsctl delete resource Command Parameters

Parameter Description
resource_name

Specify the name of the resource you want to remove.

-i

If you specify -i, then the command returns an error if processing this command requires waiting for Oracle Clusterware to unlock the resource or its dependents. Sometimes, Oracle Clusterware locks resources or other objects to prevent commands from interfering with each other.

-f

Use the force option to remove either running resources, or remove this resource even though other resources have a hard dependency on it.


Usage Notes

Example

To delete a resource from Oracle Clusterware:

# crsctl delete resource myResource

crsctl delete type

Use the crsctl delete type command to remove a resource type from the Oracle Clusterware configuration.

$ crsctl getperm type app.appvip.type

Name: app.appvip.type
owner:root:rwx,pgrp:oinstall:rwx,other::r--

crsctl modify resource

Use the crsctl modify resource command to modify the attributes of a particular resource in Oracle Clusterware.

Syntax

crsctl modify resource resource_name -attr "attribute_name=attribute_value"
[-i] [-f] [-delete]

Parameters

Table E-6 crsctl modify resource Command Parameters

Parameter Description
resource_name

The name of the resource you want to modify.

-attr "attribute_name=
attribute_value"

You can specify attributes for a resource you want to modify in two different ways:

  • Following the -attr flag, you can specify one or more comma-delimited attribute name-value pairs to modify enclosed in double quotations marks (""). For example:

    -attr "CHECK_INTERVAL=30, START_TIMEOUT=25"
    
  • Alternatively, you can specify attribute values for resources on a particular server, with a particular cardinality value, and with a particular degree value. This method can be useful for applications that are somehow tied to a particular server. Following the -attr flag, the syntax is as follows:

    attribute_name{@SERVERNAME(server_name)
    [@DEGREEID(did)] | @CARDINALITYID(cid)
    [@DEGREEID(did)]}=attribute_value
    

    If you specify the @SERVERNAME(server_name) syntax, then the attribute value you specify for the attribute you specify is limited to resources residing on the server you specify.

    Alternatively, if you specify the @CARDINALITYID(cid) syntax, then the attribute value you specify for the attribute you specify is limited to resource instances with a specific cardinality ID (cid).

    Optionally, you can combine the @DEGREEID(did) syntax with either the SERVERNAME or CARDINALITYID syntax, or both, to limit the attribute value to resources with the specific DEGREE.

    Examples:

    CHECK_INTERVAL@SERVERNAME(node1)=45
    STOP_TIMEOUT@CARDINALITYID(2)=65
    STOP_TIMEOUT@SERVERNAME(node1)@DEGREEID(2)=65
    STOP_TIMEOUT@CARDINALITYID(3)@DEGREEID(2)=65
    
-i

If you specify -i, then the command returns an error if processing this command requires waiting for Oracle Clusterware to unlock the resource or its dependents. Sometimes, Oracle Clusterware locks resources or other objects to prevent commands from interfering with each other.

-f

Use the -f option when:

  • The resource has a hard dependency on a non-existing resource

  • The owner of the resource does not have execute permissions on one or more hard dependencies

  • The modification results in servers being moved into the Generic pool and resources being stopped or relocated to accomplish the server move

-delete

If you specify the -delete option, then Oracle Clusterware deletes the named attribute.

crsctl start resource

Use the crsctl start resource command to start many idle resources on a particular server in the cluster.

Syntax

crsctl start resource {resource_name [...] | -w filter | -all} [-n server_name]
[-k cid] [-d did] [-env "env1=val1,env2=val2,..."] [-i] [-f]

Parameters

Table E-10 crsctl start resource Command Parameters

Parameter Description
resource_name [...]

One or more space-delimited resource names to start.

-w filter

Specify a resource filter that Oracle Clusterware uses to match resources.

-all

Use this option to start all resources in the cluster.

-n server_name

Specify the name of the server on which the resources you want to start reside. If you do not specify a server, then Oracle Clusterware starts the resources on the best server according to the attribute profile of each resource.

-k cid

Specify the resource cardinality ID. If you specify this parameter, then Oracle Clusterware starts the resource instances that have the cardinality you specify.

-d did

Specify the resource degree ID. If you specify this parameter and the degree ID is greater than 1, then Oracle Clusterware starts all resource instances that meet this criteria.

Note: You cannot use the -d option without specifying the -k option.

-env "env1=val1,
env2=val2,..."

You can optionally override one or more resource profile attribute values for this command. If you specify multiple environment name-value pairs, then you must separate each pair with a comma and enclose the entire list in double quotation marks ("").

-i

If you specify -i, then the command returns an error if processing this command requires waiting for Oracle Clusterware to unlock the resource or its dependents. Sometimes, Oracle Clusterware locks resources or other objects to prevent commands from interfering with each other.

-f

Use the -f option to relocate a resource running on another server on which the resource you want to start has a hard start dependency. If you do not specify the force option in this case, then the start command fails.


Usage Notes

Example

To start a resource:

# crsctl start resource myResource -n server1

crsctl status resource

Use the crsctl status resource command to obtain the status and configuration information of many particular resources.

Syntax

crsctl status resource {resource_name [...] | -w "filter"}  [-p | -v [-e]] |
[-f | -l | -g] [[-k cid | -n server_name] [-d did]] | [-s -k cid [-d did]] [-t]

Parameters

Table E-11 crsctl status resource Command Parameters

Parameter Description
resource_name [...] |
-w "filter"

One or more space-delimited resource names of which you want to check the status.

Or you can specify a resource filter that Oracle Clusterware uses to limit the number of resources displayed. The filter must be enclosed in double quotation marks (""). Values that contain parentheses or spaces must be enclosed in single quotation marks (''). Operators must be surrounded by spaces. Examples of resource filters include:

  • "TYPE == cluster_resource": This filter limits the display to only resources of cluster_resource type.

  • "CHECK_INTERVAL > 10": This filter limits the display to resources that have a value greater than 10 for the CHECK_INTERVAL resource attribute

  • "(CHECK_INTERVAL > 10) AND (NAME co 2)": This filter limits the display to resources that have a value greater than 10 for the CHECK_INTERVAL resource attribute and the name of the resource contains the number 2.

  • "START_DEPENDENCIES = 'hard(appsvip)'": This filter limits the display to resources that have a hard start dependency on the appsvip resource.

See Also: "Filters" for more information about filters

[-p | -v [-e]] | [-f | -l | -g]

You can specify one of two options: [-p | -v [-e]] or [-f | -l | -g], where:

  • Specify the -p parameter to display the static configuration of the resource or specify the -v parameter to display the run-time configuration of the resource. Use the -e parameter with the -v parameter to evaluate the special values of the resource instance.

  • Specify the -f parameter to display the full configuration of the resource; or specify the -l parameter to display all cardinal and degree values of the resource; or specify the -g parameter to check whether the specified resources are registered

[-k cid | 
-n server_name] [-d did |
[-s -k cid [-d did]]]

You can specify one of two options: [-k cid | -n server_name] or [-s -k cid [-d did]], where:

  • Specify the -k cid parameter to specify a cardinality ID of the resources you want to query. Or you can specify the -n parameter to specify a particular server on which to check resources. Optionally, you can specify the -d parameter with the -n parameter to specify the degree ID of resources you want to check. If you specify a degree ID greater than 1, then Oracle Clusterware checks all resource instances on the server that meet this criteria.

  • Specify the -s parameter with the -k parameter to obtain a list of target servers for relocation. You can further limit the output by specifying a degree ID with the -d parameter.

-t

Specify the -t parameter to display the output in tabular form.


Usage Notes

Example

The crsctl status resource command returns output similar to the following:

$ crsctl status resource ora.staii14.vip

NAME=ora.staii14.vip
TYPE=ora.cluster_vip_net1.type
TARGET=ONLINE
STATE=ONLINE on staii14

crsctl status type

Use the crsctl status type command to obtain the configuration information of one or more particular resource types.

Syntax

crsctl status type resource_type_name [...]] [-g] [-p] [-f]

Parameters

Table E-12 crsctl status type Command Parameters

Parameter Description
[resource_type_name [...]

Specify one or more space-delimited resource type names of which you want to check the status.

-g] [-p] [-f

You can specify the following parameters as options when Oracle Clusterware checks the status of specific server pools:

  • -g: Use this parameter to check if the specified resource types are registered

  • -p: Use this parameter to display static configuration of the specified resource types

  • -f: Use this parameter to display the full configuration of the resource types


Usage Notes

Example

The crsctl status type command returns output similar to the following:

$ crsctl status type ora.network.type

TYPE_NAME=ora.network.type
BASE_TYPE=ora.local_resource.type

crsctl stop resource

Use the crsctl stop resource command to stop running resources.

Syntax

Parameters

Table E-13 crsctl stop resource Command Parameters

Parameter Description
resource_name [...]

One or more space-delimited resource names to stop.

-w "filter"

Specify a resource filter that Oracle Clusterware uses to limit the number of resources stopped. The filter must be enclosed in double quotation marks (""). Examples of resource filters include:

  • "TYPE == cluster_resource": This filter limits Oracle Clusterware to stop only resources of cluster_resource type

  • "CHECK_INTERVAL > 10": This filter limits Oracle Clusterware to stop resources that have a value greater than 10 for the CHECK_INTERVAL resource attribute

  • "(CHECK_INTERVAL > 10) AND (NAME co 2)": This filter limits Oracle Clusterware to stop resources that have a value greater than 10 for the CHECK_INTERVAL resource attribute and the name of the resource contains the number 2

-all

Use this option to stop all resources in the cluster.

-n server_name

Specify the name of the server on which the resource instances you want to stop reside. If you do not specify a server, then Oracle Clusterware stops all instances of the resource.

-k cid

Specify the resource cardinality ID. If you specify this parameter, then Oracle Clusterware stops the resource instances that have the cardinality you specify.

-d did

Specify the resource degree ID. If you specify this parameter and the degree ID is greater than 1, then Oracle Clusterware stops all resource instances that meet this criteria.

-env "env1=val1,
env2=val2,..."

You can optionally override one or more resource profile attribute values for this command. If you specify multiple environment name-value pairs, then you must separate each pair with a comma and enclose the entire list in double quotation marks ("").

-i

If you specify -i, then the command returns an error if processing this command requires waiting for Oracle Clusterware to unlock the resource or its dependents. Sometimes, Oracle Clusterware locks resources or other objects to prevent commands from interfering with each other.

-f

Specify the -f option to force the stopping of the resource when it has other resources running that depend on it. Dependent resources are relocated or stopped when you use this option.


Usage Notes

Example

To stop a resource:

$ crsctl stop resource -n node1 -k 2

Oracle RAC Environment CRSCTL Commands

The commands listed in this section manage the Oracle Clusterware stack in an Oracle RAC environment, which consists of the following:

You can use the following commands only in an Oracle RAC environment:

crsctl add crs administrator

Use the crsctl add crs administrator command to add a user to the list of cluster administrators.

Syntax

crsctl add crs administrator -u user_name [-f]

Parameters

Table E-14 crsctl add crs administrator Command Parameters

Parameter Description
-u user_name

The name of the user to whom you want to give Oracle Clusterware administrative privileges.

-f

Use this option to override the user name validity check.


Usage Notes

Example

To add a user to the list of Oracle Clusterware administrators:

# crsctl add crs administrator -u scott

crsctl add css votedisk

Use the crsctl add css votedisk command to add one or more voting disks to the cluster on storage devices or to ASM diskgroup with redundancy normal or high.

Note:

if disk group redundancy is set to external, then you can only create one voting disk in the ASM disk group. If you try to add multiple voting disks, then Oracle returns an error.

Use the crsctl add css votedisk command to add one or more voting disks to the cluster on storage devices or to an Oracle ASM disk group with normal or high redundancy.

Syntax

crsctl add css votedisk path_to_voting_disk [path_to_voting_disk ...] [-purge]

Parameters

crsctl add serverpool

Use the crsctl add serverpool command to add a server pool to Oracle Clusterware.

Syntax

crsctl add serverpool server_pool_name {-file file_path | 
                  -attr "attr_name=attr_value[,attr_name=attr_value[,...]]"}
                  [-i] [-f]

Parameters

Table E-16 crsctl add serverpool Command Parameters

Parameter Description
server_pool_name

A short, descriptive name for the server pool.

-file file_path

Fully-qualified path to an attribute file to define the server pool.

attribute_name

The name of a server pool attribute Oracle Clusterware uses to manage the server pool preceded by the -attr flag. The available attribute names include:

  • IMPORTANCE

  • MIN_SIZE

  • MAX_SIZE

  • SERVER_NAMES

  • PARENT_POOLS

  • EXCLUSIVE_POOLS

  • ACL

  • ACTIVE_SERVERS

attribute_value

A value for the server pool attribute.

Note: The attribute_name and attribute_value parameters must be enclosed in double quotation marks ("") and separated by commas. For example:

-attr "MAX_SIZE=30, IMPORTANCE=3"
-i

If you specify -i, then the command fails if Oracle Clusterware cannot process the request immediately.

-f

If you specify the -f option, then Oracle Clusterware stops resources running on a server in another server pool and relocates that server into the server pool you are adding. If you do not specify the -f option, then Oracle Clusterware checks whether the creation of the server pool results in stopping any resources on a server in another server pool that is going to give up a server to the server pool you are adding. If so, then Oracle Clusterware rejects the crsctl add serverpool command.

-k cid

Specify the resource cardinality ID. If you specify this parameter, then Oracle Clusterware relocates the resource instance that have the cardinality you specify.

-env "env1=val1,
env2=val2,..."

You can optionally override one or more resource profile attribute values for this command. If you specify multiple environment name-value pairs, then you must separate each pair with a comma and enclose the entire list in double quotation marks ("").

-i

If you specify -i, then the command returns an error if processing this command requires waiting for Oracle Clusterware to unlock the resource or its dependents. Sometimes, Oracle Clusterware locks resources or other objects to prevent commands from interfering with each other.

-f

Specify the -f option to force the relocating of the resource when it has other resources running that depend on it. Dependent resources are relocated or stopped when you use this option.

Note: When you are relocating resources that have cardinality greater than 1, you must use either -k or -s to narrow down which resource instances are to be relocated.

Troubleshooting and Diagnostic Output

You can use crsctl set log commands as the root user to enable dynamic debugging for Cluster Ready Services (CRS), Cluster Synchronization Services (CSS), and the Event Manager (EVM), and the clusterware subcomponents. You can dynamically change debugging levels using crsctl debug commands. Debugging information remains in the Oracle Cluster Registry (OCR) for use during the next startup. You can also enable debugging for resources.

This section covers the following topics:


Dynamic Debugging

This section includes the following CRSCTL commands that aid in debugging:

crsctl set log

Use the crsctl set log command to set log levels for Oracle Clusterware.

Syntax

crsctl set log {[crs | css | evm "component_name=log_level, [...]"] | 
[all=log_level]}

You can also set log levels for the agents of specific resources, as follows:

crsctl set log res "resource_name=log_level, [...]"

Usage Notes

Examples

To set log levels for the CRSRTI and CRSCOMM components of the CRS module:

$ crsctl set log crs "CRSRTI=1,CRSCOMM=2"

To set log levels for all components of the EVM module:

$ crsctl set log evm all=2

To set a log level for a resource:

$ crsctl set log res "myResource1=3"

crsctl set trace

Use the crsctl set trace command to set tracing levels for Oracle Clusterware.

Syntax

crsctl set trace {[crs | evm "component_name=tracing_level, [...]"] | 
["all=tracing_level"]

Usage Notes

Examples

To set tracing levels for the CRSCCL and CRSEVT components of the CRS module:

$ crsctl set trace crs "CRSCCL=1,CRSEVT=2"

Component Level Debugging

You can use crsctl set log and crsctl set trace commands as the root user to enable dynamic debugging for the Oracle Clusterware Cluster Ready Services (CRS), Cluster Synchronization Services (CSS), and the Event Manager (EVM).

This section includes the following topics:

Enabling Debugging for CRS, CSS, and EVM Modules

You can enable debugging for the CRS, CSS, and EVM modules and their components, and for resources, by setting environment variables or by issuing crsctl set log commands, using the following syntax:

crsctl set {log | trace} module_name 
 “component:debugging_level[,component:debugging_level][...]”

Run the crsctl set command as the root user, and supply the following information:

The following commands show examples of how to enable debugging for the various modules:

To obtain a list of components that can be used for debugging, run the crsctl lsmodules command, as follows:

crsctl lsmodules {crs | css | evm}

Note:

You do not have to be the root user to run the crsctl lsmodulues command.

Table E-40 shows the components for the CRS, CSS, and EVM modules, respectively. Note that some component names are common between the CRS, EVM, and CSS daemons and may be enabled on that specific daemon. For example, COMMNS is the NS layer and because each daemon uses the NS layer, you can enable this specific module component on any of the daemons to get specific debugging information.

Creating an Initialization File to Contain the Debugging Level

This section describes how to specify the debugging level in an initialization file. This debugging information is stored for use during the next startup.

For each process to debug, you can create an initialization file that contains the debugging level.

The initialization file name includes the name of the process that you are debugging (process_name.ini). The file is located in the Grid_home/log/host_name/admin/ directory. For example, the name for the CLSCFG debugging initialization file on node1 would be:

Grid_home/log/node1/admin/clscfg.ini

You can also use an initialization file when using OCR utilities. The initialization file for ocrconfig, ocrdump, and ocrcheck is:

Grid_home/srvm/admin/ocrlog.ini

The format of the initialization file is as follows:

mesg_logging_level=2
comploglvl=”OCRAPI:0;OCRSRV:0”
comptrclvl=”OCRAPI:0;OCRSRV:0”

You can specify component names, logging, and tracing levels.

See Also:

"Enabling Debugging for CRS, CSS, and EVM Modules" for information about dynamically changing debugging levels by specifying the level number (from 1 to 5) on the crsctl command

Enabling Additional Tracing for Oracle Clusterware High Availability

My Oracle Support may ask you to enable tracing to capture additional information. Because the procedures described in this section may affect performance, only perform these activities with the assistance of My Oracle Support.

Enabling Debugging for Oracle Clusterware Resources

You can enable debugging for Oracle Clusterware resources by issuing crsctl set log and crsctl set trace commands, using the following syntax:

crsctl set {log | trace} resource “resource_name=debugging_level” 

Run the crsctl set command as the root user, and supply the following information:

Note:

You must run this crsctl set log or crsctl set trace command as the root user.

To obtain a list of resources that can be used for debugging, run the crsctl status resource command.

Example 1    

To generate a debugging log for the VIP resource on node1, issue the following command:

crsctl set log resource "ora.node1.vip:1"
Example 2    

To generate a trace file for a SCAN listener, use the following command:

crsctl set trace resource "ora.LISTENER_SCAN1.lsnr=3”
