ssbdiagnose Utility (Service Broker)

The ssbdiagnose utility reports issues in Service Broker conversations or the configuration of Service Broker services. Configuration checks can be made for either two services or a single service. Issues are reported either in the command prompt window as human-readable text, or as formatted XML that can be redirected to a file or another program.

-XML

Specifies that the ssbdiagnose output be generated as formatted XML. This can be redirected to a file or to another application. If -XML is not specified, the ssbdiagnose output is formatted as human-readable text.

-LEVEL { ERROR | WARNING | INFO}

Specifies the level of messages to report.

ERROR: report only error messages.

WARNING: report error and warning messages.

INFO: report error, warning, and informational messages.

The default setting is WARNING.

-IGNORE error_id

Specifies that errors or messages that have the specified error_id not be included in reports. You can specify -IGNORE multiple times to suppress multiple message IDs.

<baseconnectionoptions>

Specifies the base connection information that is used by ssbdiagnose when connection options are not included in a specific clause. The connection information that is given in a specific clause overrides the baseconnectionoption information. This is performed separately for each parameter. For example, if both -S and -d are specified in baseconnetionoptions, and only -d is specified in toconnetionoptions, ssbdiagnose uses -S from baseconnetionoptions and -d from toconnetionoptions.

CONFIGURATION

Requests a report of configuration errors between a pair of Service Broker services, or for a single service.

FROM SERVICE service_name

Specifies the service that initiates conversations.

<fromconnectionoptions>

Specifies the information that is required to connect to the database that holds the initiator service. If fromconnectionoptions is not specified, ssbdiagnose uses the connection information from baseconnectionoptions to connect to the initiator database. If fromconnectionoptions is specified it must include the database that contains the initiator service. If fromconnectionoptions is not specified, the baseconnectionoptions must specify the initiator database.

TO SERVICE service_name[, broker_id ]

Specifies the service that is the target for the conversations.

service_name: specifies the name of the target service.

broker_id: specifies the Service Broker ID that identifies the target database. broker_id is a GUID. You can run the following query in the target database to find it:

SELECT service_broker_guid
FROM sys.databases
WHERE database_id = DB_ID();
<toconnectionoptions>

Specifies the information that is required to connect the database that holds the target service. If toconnectionoptions is not specified, ssbdiagnose uses the connection information from baseconnectionoptions to connect to the target database.

MIRROR

Specifies that the associated Service Broker service is hosted in a mirrored database. ssbdiagnose verifies that the route to the service is a mirrored route, where MIRROR_ADDRESS was specified on CREATE ROUTE.

<mirrorconnectionoptions>

Specifies the information that is required to connect to the mirror database. If mirrorconnectionoptions is not specified, ssbdiagnose uses the connection information from baseconnectionoptions to connect to the mirror database.

ON CONTRACT contract_name

Requests that ssbdiagnose only check configurations that use the specified contract. If ON CONTRACT is not specified, ssbdiagnose reports on the contract named DEFAULT.

ENCRYPTION { ON | OFF | ANONYMOUS }

Requests verification that the dialog is correctly configured for the specified level of encryption:

ON: Default setting. Full dialog security is configured. Certificates have been deployed on both sides of the dialog, a remote service binding is present, and the GRANT SEND statement for the target service specified the initiator user.

OFF: No dialog security is configured. No certificates have been deployed, no remote service binding was created, and the GRANT SEND for the initiator service specified the public role.

ANONYMOUS: Anonymous dialog security is configured. One certificate has been deployed, the remote service binding specified the anonymous clause, and the GRANT SEND for the target service specified the public role.

RUNTIME

Requests a report of issues that cause runtime errors for a Service Broker conversation. If neither -NEW or -ID are specified, ssbdiagnose monitors all conversations in all databases specified in the connection options. If -NEW or -ID are specified, ssbdiagnose builds a list of the IDs specified in the parameters.

While ssbdiagnose is running, it records all SQL Server Profiler events that indicate runtime errors. It records the events that occur for the specified IDs, plus system-level events. If runtime errors are encountered, ssbdiagnose runs a configuration report on the associated configuration.

By default, runtime errors are not included in the output report, only the results of the configuration analysis. Use -SHOWEVENTS to have the runtime errors included in the report.

-SHOWEVENTS

Specifies that ssbdiagnose report SQL Server Profiler events during a RUNTIME report. Only events that are considered error conditions are reported. By default, ssbdiagnose only monitors error events; it does not report them in the output.

-NEW

Requests runtime monitoring of the first conversation that begins after ssbdiagnose starts running.

-ID

Requests runtime monitoring of the specified conversation elements. You can specify -ID multiple times.

If you specify a conversation handle, only events associated with the associated conversation endpoint are reported. If you specify a conversation ID, all events for that conversation and its initiator and target endpoints are reported. If a conversation group ID is specified, all events for all conversations and endpoints in the conversation group are reported.

conversation_handle

A unique identifier that identifies a conversation endpoint in an application. Conversation handles are unique to one endpoint of a conversation, the initiator and target endpoints have separate conversation handles.

Conversation handles are returned to applications by the @dialog_handle parameter of the BEGIN DIALOG statement, and the conversation_handle column in the result set of a RECEIVE statement.

Conversation handles are reported in the conversation_handle column of the sys.transmission_queue and sys.conversation_endpoints catalog views.

conversation_group_id

The unique identifier that identifies a conversation group.

Conversation group IDs are returned to applications by the @conversation_group_id parameter of the GET CONVERSATION GROUP statement and the conversation_group_id column in the result set of a RECEIVE statement.

Conversation group IDs are reported in the conversation_group_id columns of the sys.conversation_groups and sys.conversation_endpoints catalog views.

conversation_id

The unique identifier that identifies a conversation. Conversation IDs are the same for both the initiator and target endpoints of a conversation.

Conversation IDs are reported in the conversation_id column of the sys.conversation_endpoints catalog view.

-TIMEOUT timeout_interval

Specifies the number of seconds for a RUNTIME report to run. If -TIMEOUT is not specified the runtime report runs indefinitely. -TIMEOUT is used only on RUNTIME reports, not CONFIGURATION reports. Use ctrl + C to quit ssbdiagnose if -TIMEOUT was not specified or to end a runtime report before the time-out interval expires. timeout_interval must be a number between 1 and 2,147,483,647.

<runtimeconnectionoptions>

Specifies the connection information for the databases that contain the services associated with conversation elements being monitored. If all the services are in the same database, you only have to specify one CONNECT TO clause. If the services are in separate databases you must supply a CONNECT TO clause for each database. If runtimeconnectionoptions is not specified, ssbdiagnose uses the connection information from baseconnectionoptions.

–E

Open a Windows Authentication connection to an instance of the Database Engine by using your current Windows account as the login ID. The login must be a member of the sysadmin fixed-server role.

The -E option ignores the user and password settings of the SQLCMDUSER and SQLCMDPASSWORD environment variables.

If neither -E nor -U is specified, ssbdiagnose uses the value from the SQLCMDUSER environment variable. If SQLCMDUSER is not set either, ssbdiagnose uses Windows Authentication.

If the -E option is used together with the -U option or the -P option, an error message is generated.

-U login_id

Open a SQL Server Authentication connection by using the specified login ID. The login must be a member of the sysadmin fixed-server role.

If neither -E nor -U is specified, ssbdiagnose uses the value from the SQLCMDUSER environment variable. If SQLCMDUSER is not set either, ssbdiagnose tries to connect by using Windows Authentication mode based on the Windows account of the user who is running ssbdiagnose.

If the -U option is used together with the -E option, an error message is generated. If the –U option is followed by more than one argument, an error message is generated and the program exits.

-P password

Specifies the password for the -U login ID. Passwords are case sensitive. If the -U option is used and the -P option is not used, ssbdiagnose uses the value from the SQLCMDPASSWORD environment variable. If SQLCMDPASSWORD is not set either, ssbdiagnose prompts the user for a password.

Security note Security Note

When you type a SET SQLCMDPASSWORD command, your password will be visible to anyone who can see your monitor.

If the -P option is specified without a password ssbdiagnose uses the default password (NULL).

Security note Security Note

Do not use a blank password. Use a strong password. For more information, see Strong Passwords.

The password prompt is displayed by printing the password prompt to the console, as follows: Password:

User input is hidden. This means that nothing is displayed and the cursor stays in position.

If the -P option is used with the -E option, an error message is generated.

If the -P option is followed by more than one argument, an error message is generated.

-S server_name[\instance_name]

Specifies the instance of the Database Engine that holds the Service Broker services to be analyzed.

Specify server_name to connect to the default instance of the Database Engine on that server. Specify server_name\instance_name to connect to a named instance of the Database Engine on that server. If -S is not specified, ssbdiagnose uses the value of the SQLCMDSERVER environment variable. If SQLCMDSERVER is not set either, ssbdiagnose connects to the default instance of the Database Engine on the local computer.

-d database_name

Specifies the database that holds the Service Broker services to be analyzed. If the database does not exist, an error message is generated. If -d is not specified, the default is the database specified in the default-database property for your login.

-l login_timeout

Specifies the number of seconds before an attempt to connect to a server times out. If -l is not specified, ssbdiagnose uses the value set for the SQLCMDLOGINTIMEOUT environment variable. If SQLCMDLOGINTIMEOUT is not set either, the default time-out is thirty seconds. The login time-out must be a number between 0 and 65534. If the value that is supplied is not numeric or does not fall into that range, ssbdiagnose generates an error message. A value of 0 specifies time-out to be infinite.

-?

Displays command line help.

Use ssbdiagnose to do the following:

  • Confirm that there are no configuration errors in a newly configured Service Broker application.

  • Confirm that there are no configuration errors after changing the configuration of an existing Service Broker application.

  • Confirm that there are no configuration errors after a Service Broker database is detached and then reattached to a new instance of the Database Engine.

  • Research whether there are configuration errors when messages are not successfully transmitted between services.

  • Get a report of any errors that occur in a set of Service Broker conversation elements.

Configuration Reporting

To correctly analyze the configuration used by a conversation, run a ssbdiagnose configuration report that uses the same options that are used by the conversation. If you specify a lower level of options for ssbdiagnose than are used by the conversation, ssbdiagnose might not report conditions that are required by the conversation. If you specify a higher level of options for ssbdiagnose, it might report items that are not required by the conversation. For example, a conversation between two services in the same database can be run with ENCPRYPTION OFF. If you run ssbdiagnose to validate the configuration between the two services, but use the default ENCRYPTION ON setting, ssbdiagnose reports that the database is missing a master key. A master key is not required for the conversation.

The ssbdiagnose configuration report analyzes only one Service Broker service or a single pair of services every time it is run. To report on multiple pairs of Service Broker services, build a .cmd command file that calls ssbdiagnose multiple times.

Runtime Reporting

When -RUNTIME is specified, ssbdiagnose searches all databases specified in runtimeconnectionoptions and baseconnectionoptions to build a list of Service Broker IDs. The full list of IDs built depends on what is specified for -NEW and -ID:

  • If neither -NEW or -ID are specified, the list includes all conversations for all databases specified in the connection options.

  • If -NEW is specified, ssbdiagnose includes the elements for the first conversation that starts after ssbdiagnose is run. This includes the conversation ID and the conversation handles for both the target and initiator conversation endpoints.

  • If -ID is specified with a conversation handle, only that handle is included in the list.

  • If -ID is specified with a conversation ID, the conversation ID and the handles for both of its conversation endpoints are added to the list.

  • If -ID is specified with a conversation group ID, all the conversation IDs and conversation handles in that group are added to the list.

The list does not include elements from databases that are not covered by the connection options. For example, assume that you use -ID to specify a conversation ID, but only provide a runtimeconnectionoptions clause for the initiator database and not the target database. ssbdiagnose will not include the target conversation handle in its list of IDs, only the conversation ID and the initiator conversation handle.

ssbdiagnose monitors the SQL Server Profiler events from the databases covered by runtimeconnectionoptions and baseconnectionoptions. It searches for Service Broker events that indicate an error was encountered by one or more of the Service Broker IDs in the runtime list. ssbdiagnose also searches for system-level Service Broker error events not specifically associated with any conversation group.

If ssbdiagnose finds conversation errors, the utility will attempt to report on the root cause of the events by also running a configuration report. ssbdiagnose uses the metadata in the databases to try to determine the instances, Service Broker IDs, databases, services, and contracts used by the conversation. It then runs a configuration report using all available information.

By default, ssbdiagnose does not report error events. It only reports the underlying issues found during the configuration check. This minimizes the amount of information reported and helps you focus on the underlying configuration issues. You can specify -SHOWEVENTS to see the error events encountered by ssbdiagnose.

Issues Reported by ssbdiagnose

ssbdiagnose reports three classes of issues. In the XML output file, each class of issue is reported as a separate type of the Issue element. The three types of issues reported by ssbdiagnose are as follows:

Diagnosis

Reports a configuration issue. This includes issues found either a CONFIGURATION report is running, or during the configuration phase of a RUNTIME report. ssbdiagnose reports each configuration issue one time.

Event

Reports a SQL Server Profiler event that indicates a problem was encountered by a conversation being monitored during a RUNTIME report. ssbdiagnose reports events every time they are generated. Events can be reported multiple times if several conversations encounter the problem.

Problem

Reports an issue that is preventing ssbdiagnose from completing a configuration analysis or from monitoring conversations.

sqlcmd Environment Variables

The ssbdiagnose utility supports the SQLCMDSERVER, SQLCMDUSER, SQLCMDPASSWORD, and SQLCMDLOGINTIMOUT environment variables that are also used by the sqlcmd utility. You can set the environment variables either by using the command prompt SET command, or by using the setvar command in Transact-SQL scripts that you run by using sqlcmd. For more information about how to use setvar in sqlcmd, see Use sqlcmd with Scripting Variables.

In each connectionoptions clause, the login specified with either -E or -U must be a member of the sysadmin fixed-server role in the instance specified in -S.

This section contains examples of using ssbdiagnose at a command prompt.

A. Checking the Configuration of Two Services in the Same Database

The following example shows how to request a configuration report when the following are true;

  • The initiator and target service are in the same database.

  • The database is in the default instance of the Database Engine.

  • The instances is on the same computer on which ssbdiagnose is run.

The ssbdiagnose utility reports the configuration that uses the DEFAULT contract because ON CONTRACT is not specified.

ssbdiagnose -E -d MyDatabase CONFIGURATION FROM SERVICE /test/initiator TO SERVICE /test/target

B. Checking the Configuration of Two Services on Separate Computers That Use One Login

The following example shows how to request a configuration report when the initiator and target service are on separate computers, but can be accessed by using the same Windows Authentication login.

ssbdiagnose -E CONFIGURATION FROM SERVICE /text/initiator -S InitiatorComputer -d InitiatorDatabase TO SERVICE /test/target -S TargetComputer -d TargetDatabase ON CONTRACT TestContract

C. Checking the Configuration of Two Services on Separate Computers That Use Separate Logins

The following example shows how to request a configuration report when the initiator and target service are on separate computers, and separate SQL Server Authentication logins are required for each instance of the Database Engine.

ssbdiagnose CONFIGURATION FROM SERVICE /text/initiator 
-S InitiatorComputer -U InitiatorLogin -p !wEx23Dvb 
-d InitiatorDatabase TO SERVICE /test/target -S TargetComputer 
-U TargetLogin -p ER!49jiy -d TargetDatabase ON CONTRACT TestContract

D. Checking Mirrored Service Configurations on Separate Computers With Anonymous Encryption

The following example shows how to request a configuration report when the initiator and target service are on separate computers and the initiator is mirrored to a named instance. The report also verifies that the services are configured to use anonymous encryption.

ssbdiagnose -E CONFIGURATION FROM SERVICE /text/initiator 
-S InitiatorComputer -d InitiatorDatabase MIRROR 
-S MirrorComputer/MirrorInstance TO SERVICE /test/target 
-S TargetComputer -d TargetDatabase ON CONTRACT TestContract ENCRYPTION ANONYMOUS

E. Checking the Configuration of Two Contracts

The following example shows how to build a command file that requests configuration reports when the following are true:

  • The initiator and target service are in the same database.

  • The database is in the default instance of the Database Engine.

  • The instance is on the same computer on which ssbdiagnose is run.

Each time ssbdiagnose is run it reports the configuration for a different contract between the same services.

ssbdiagnose -E -d MyDatabase CONFIGURATION FROM SERVICE 
/test/initiator TO SERVICE /test/target ON CONTRACT PayRaiseContract
ssbdiagnose -E -d MyDatabase CONFIGURATION FROM SERVICE /test/initiator 
TO SERVICE /test/target ON CONTRACT PromotionContract

F. Monitor the status of a specific conversation on the local computer with a time out

The following example shows how to monitor a specific conversation where the initiator and target services are in the same database in the default instance of the same computer that is running ssbdiagnose. The time-out interval is set to 20 seconds.

ssbdiagnose -E -d TestDatabase RUNTIME -ID D68D77A9-B1CF-41BF-A5CE-279ABCAB140D -TIMEOUT 20

G. Monitor the status of a conversation that spans two computers

The following example shows how to monitor a specific conversation where the initiator and target services are on separate computers.

ssbdiagnose RUNTIME -ID D68D77A9-B1CF-41BF-A5CE-279ABCAB140D 
-TIMEOUT 10 CONNECT TO -E -S InitiatorComputer/InitiatorInstance 
-d InitiatorDatabase CONNECT TO -E -S TargetComputer/TargetInstance 
-d TargetDatabase

H. Monitor the status of a conversation in two databases in the same instance

The following example shows how to monitor a specific conversation where the initiator and target services are in separate databases in the same instance of the Database Engine. The example uses the baseconnectionoptions to specify the instance and login information, and two CONNECT TO clauses to specify the databases. -SHOWEVENTS is specified so that all runtime events are included in the report output.

ssbdiagnose -E -S TestComputer/DevTestInstance RUNTIME -SHOWEVENTS 
-ID 5094d4a7-e38c-4c37-da37-1d58b1cb8455 -TIMEOUT 10 CONNECT TO 
-d InitiatorDatabase CONNECT TO -d TargetDatabase

I. Monitor the status of two conversations between two databases

The following example shows how to monitor two conversations where the initiator and target services are in separate databases in the same instance of the Database Engine. The example uses the baseconnectionoptions to specify the instance and login information, and two CONNECT TO clauses to specify the databases.

ssbdiagnose -E -S TestComputer/DevTestInstance RUNTIME 
-ID 5094d4a7-e38c-4c37-da37-1d58b1cb8455 
-ID 9b293be9-226b-4e22-e169-1d2c2c15be86 -TIMEOUT 10 CONNECT TO 
-d InitiatorDatabase CONNECT TO -d TargetDatabase

J. Monitor the status of all conversations between two databases

The following example shows how to monitor all the conversation between two databases in the same instance of the Database Engine. The example uses the baseconnectionoptions to specify the instance and login information, and two CONNECT TO clauses to specify the databases.

ssbdiagnose -E -S TestComputer/DevTestInstance RUNTIME 
-TIMEOUT 10 CONNECT TO -d InitiatorDatabase CONNECT TO 
-d TargetDatabase

K. Ignore Specific Errors

The following example shows how to ignore known errors (303 and 304) in how activation is currently configured in a test system.

ssbdiagnose -IGNORE 303 -IGNORE 304 -E -d TestDatabase 
CONFIGURATION FROM SERVICE /test/initiator TO SERVICE /test/target 
ON CONTRACT TextContract

L. Redirecting ssbdiagnose XML Output

The following example shows how to request that ssbdiagnose generate its output as an XML file that is redirected to a file. The TestDiag.xml file can then be opened by an application to analyze or report ssbdiagnose XML files. Or, you can view it from a general XML editor such as XML Notepad.

ssbdiagnose -XML -E -d MyDatabase CONFIGURATION FROM SERVICE 
/test/initiator TO SERVICE /test/target > c:\MyDiagnostics\TestDiag.xml

M. Using an Environment Variable

The following example first sets the SQLCMDSERVER environment variable to hold the server name, and then runs ssbdiagnose without specifying -S.

SET SQLCMDSERVER=MyComputer
ssbdiagnose -XML -E -d MyDatabase CONFIGURATION FROM SERVICE 
/test/initiator TO SERVICE /test/target
