char* RTI_PersistenceServiceProperty::cfg_file

Path to an RTI Persistence Service configuration file.

If not NULL, this file is loaded; otherwise, if cfg_strings is not NULL, that XML code is loaded

[default] NULL.

const char** RTI_PersistenceServiceProperty::cfg_strings

XML configuration represented as strings.

An array of strings that altogether make up an XML document to configure RTI Persistence Service. This parameter is used only if cfg_file is NULL.

For example:

int MY_PERSISTENCE_SERVICE_CFG_SIZE = 3;
const char * MY_PERSISTENCE_SERVICE_CFG[MY_PERSISTENCE_SERVICE_CFG_SIZE] = 
                         {"<dds><persistence_service>",
                          "<participant name=\"defaultParticipant\"><persistence_group name=,
                          "\"groupName\">...</dds>"};
property.cfg_strings = MY_PERSISTENCE_SERVICE_CFG;
property.cfg_strings_count = MY_PERSISTENCE_SERVICE_CFG_SIZE;

The reason for using an array instead of one single string is to get around the limited size of literal strings in C. In general, if you create the XML string dynamically using one single string in the array, setting cfg_strings_count to 1 is enough:

property.cfg_strings = malloc(sizeof(char *));
property.cfg_strings[0] = "<dds><routing_service>...</dds>";
property.cfg_strings_count = 1;

If your target system doesn't support a file system, you can configure the service using XML strings.

[default] NULL.

int RTI_PersistenceServiceProperty::cfg_strings_count

Size of the array cfg_strings.

[default] 0.

char* RTI_PersistenceServiceProperty::cfg_name

Configuration name. This parameter is required and it is used to find a <persistence_service> matching tag in the configuration file.

[default] NULL.

char* RTI_PersistenceServiceProperty::application_name

Assigns a name to the execution of the RTI Persistence Service.

Remote commands will refer to the persistence service using this name. In addition, the name of DomainParticipants created by RTI Persistence Service will be based on this name.

[default] The value of cfg_name if different than NULL. Otherwise, "RTI_Persistence_Service".

DDS_Boolean RTI_PersistenceServiceProperty::identify_execution

Set this to true to append the host name and process ID to the RTI Persistence Service application name.

Used to get unique names for remote administration.

[default] DDS_BOOLEAN_FALSE

int RTI_PersistenceServiceProperty::domain_id

DDS domain ID for the DomainParticipants created by the service.

[default] -1 (Use the XML value)

DDS_Boolean RTI_PersistenceServiceProperty::enable_administration

Set this to true to enable remote administration or false to disable it.

[default] DDS_BOOLEAN_FALSE

int RTI_PersistenceServiceProperty::administration_domain_id

If enable_administration is true, this is the domain ID to use for remote administration.

Takes precedence over the XML configuration. If enable_administration is false, this value is not used even if remote administration is enabled in the XML configuration.

[default] 0

int RTI_PersistenceServiceProperty::thread_stack_size

RTI Persistence Service thread stack size, used to specify a stack size for the main service thread.

[default] RTI_OSAPI_THREAD_STACK_SIZE_DEFAULT

char* RTI_PersistenceServiceProperty::info_dir

The info directory of the running RTI Persistence Service.

The service writes a ps.pid file into this directory when is started. When the service finalizes the file is deleted.

The ps.pid file is used to check if the last execution of RTI Persistence Service finished gracefully or there were errors

[default] NULL (the file ps.pid will not be used)

int RTI_PersistenceServiceProperty::restore

Indicates whether or not RTI Persistence Service must restore its state from the persistent storage.

Set to 0 to not restore the state Set to 1 to restore the state Set to -1 to use the XML value for restore

[default] -1 Use the XML value

int RTI_PersistenceServiceProperty::service_verbosity

The verbosity of RTI Persistence Service.

Values:

[default] RTI_PERSISTENCE_SERVICE_LOG_VERBOSITY_EXCEPTIONS

int RTI_PersistenceServiceProperty::dds_verbosity

The verbosity of RTI Connext core libraries.

Values:

[default] RTI_PERSISTENCE_SERVICE_LOG_VERBOSITY_EXCEPTIONS

char* RTI_PersistenceServiceProperty::license_file

Path to an RTI Persistence Service license file.

If not NULL, this file is checked for a valid license; otherwise, default location will be used. This parameter is not used in unlicensed versions.

[default] NULL.

DDS_Boolean RTI_PersistenceServiceProperty::enable_database_locking

Enable database locking.

Persistence Service will lock the database by creating an entry in a specific table in the datatabase

This entry is to avoid multiple instances of RTI Persistence Service are accessing to the same database at the same time.

[default] DDS_BOOLEAN_TRUE
