#define TIBDG_CONNECTION_BINDSTRATEGY_RANDOM   (0)

◆ TIBDG_CONNECTION_HTTPS_CONNECTION_TRUST_EVERYONE

#define TIBDG_CONNECTION_HTTPS_CONNECTION_TRUST_EVERYONE   "trust_everyone"

Trust any realm server; property value constant.

This constant is one possible value of the property TIBDG_CONNECTION_PROPERTY_STRING_TRUST_TYPE in the method tibdgGrid_Connect.

The client trusts any realm server without verifying trust in the server's certificate. Do not use this value except for convenience in development and testing. It is not secure.

◆ TIBDG_CONNECTION_HTTPS_CONNECTION_USE_SPECIFIED_TRUST_FILE

#define TIBDG_CONNECTION_HTTPS_CONNECTION_USE_SPECIFIED_TRUST_FILE   "trust_file"

Trust a realm server if its certificate is in a trust file; property value constant.

This constant is one possible value of the property TIBDG_CONNECTION_PROPERTY_STRING_TRUST_TYPE in the method tibdgGrid_Connect.

The client trusts the realm server based on the trust file created by the realm server and distributed by the administrator.

Specify the file path of the trust file in the property TIBDG_CONNECTION_PROPERTY_STRING_TRUST_FILE.

◆ TIBDG_CONNECTION_PROPERTY_DOUBLE_CONNECT_WAIT_TIME

#define TIBDG_CONNECTION_PROPERTY_DOUBLE_CONNECT_WAIT_TIME   "com.tibco.tibdg.connectwaittime"

Property name for initial connection timeout; double.

When connecting to a data grid, supply this property to tibdgGrid_Connect. This value sets the fixed amount of time the call will wait inside tibdgGrid_Connect while it collects proxy responses. The value must be set to greater than the client-proxy roundtrip time or the connection will fail and must be retried. Default is 0.1 seconds. This value should generally be kept to less than 10 seconds. For ways to reduce to reduce the binding time, refer to the documentation for TIBDG_CONNECTION_PROPERTY_LONG_BINDSTRATEGY and related properties.

Note: this duration applies once the realm connection has been established. If the realm server experiences disruption, up to 5 additional seconds may be required.

◆ TIBDG_CONNECTION_PROPERTY_DOUBLE_TIMEOUT

#define TIBDG_CONNECTION_PROPERTY_DOUBLE_TIMEOUT   "com.tibco.tibdg.timeout"

Property name for connection timeout; double.

When connecting to a data grid, supply this property to tibdgGrid_Connect. Its value determines how long all calls, other than tibdgGrid_Connect, block waiting for the data grid to respond. Default is 5.0 seconds.

#define TIBDG_CONNECTION_PROPERTY_LONG_BINDSTRATEGY   "com.tibco.tibdg.connectbindstrategy"

Property name for specifying how a client chooses a proxy to establish a connection.

Supply this property to tibdgGrid_Connect.

TIBDG_BINDSTRATEGY_RANDOM will choose a proxy at random from the responses received. TIBDG_BINDSTRATEGY_NAMED will choose only a proxy supplied using the property TIBDG_CONNECTION_PROPERTY_STRING_CONNECT_PROXYNAMES

◆ TIBDG_CONNECTION_PROPERTY_LONG_CONNECT_NUMRESPONSES

#define TIBDG_CONNECTION_PROPERTY_LONG_CONNECT_NUMRESPONSES   "com.tibco.tibdg.connectnumresponses"

Property to cutoff wait time using TIBDG_BINDSTRATEGY_RANDOM.

No effect for other bind strategies

After receiving this many responses, the client will stop looking for additional responses

#define TIBDG_CONNECTION_PROPERTY_LONG_REALM_CONNECT_RETRIES   "com.tibco.tibdg.realmconnectretries"

Property name for initial realm connection retries; long.

When connecting to a data grid, supply this property to tibdgGrid_Connect. This value sets the number of times the underlying TIBCO FTL client library will attempt to connect to the Realm. The default is 5.

◆ TIBDG_CONNECTION_PROPERTY_STRING_CLIENT_LABEL

#define TIBDG_CONNECTION_PROPERTY_STRING_CLIENT_LABEL   "com.tibco.tibdg.clientlabel"

Property name for client label; string.

It is good practice to include this property in tibdgGrid_Connect calls of every application program. Administrators can use client labels in monitoring and management to recognize and distinguish among processes.

◆ TIBDG_CONNECTION_PROPERTY_STRING_CONNECT_PROXYNAMES

#define TIBDG_CONNECTION_PROPERTY_STRING_CONNECT_PROXYNAMES   "com.tibco.tibdg.connectproxynames"

Property name for specifying pipe '|' delimited list of proxy names for TIBDG_BINDSTRATEGY_NAMED.

#define TIBDG_CONNECTION_PROPERTY_STRING_SECONDARY_REALM   "com.tibco.tibdg.connection.secondaryrealm"

Property name for specifying secondary/backup realm server; string.

When connecting to a data grid, supply this property to tibdgGrid_Connect. This value sets the url of the realm server to use in case of failures of the primary

◆ TIBDG_CONNECTION_PROPERTY_STRING_TRUST_FILE

#define TIBDG_CONNECTION_PROPERTY_STRING_TRUST_FILE   "com.tibco.tibdg.trust.file"

Property name for secure realm server trust file; string.

When connecting to a secure realm server, supply this property to tibdgGrid_Connect.

If the grid connect call specifies the trust type as TIBDG_CONNECTION_HTTPS_CONNECTION_USE_SPECIFIED_TRUST_FILE, use this property to indicate the location of the trust file.

◆ TIBDG_CONNECTION_PROPERTY_STRING_TRUST_TYPE

#define TIBDG_CONNECTION_PROPERTY_STRING_TRUST_TYPE   "com.tibco.tibdg.trust.type"

Property name for secure realm server trust type; long.

This error code will be returned when a client submits any operation that modifies the data on disk while the grid is in maintenance mode.

◆ TIBDG_GRIDMETADATA_PROPERTY_STRING_CHECKPOINT_NAME

#define TIBDG_GRIDMETADATA_PROPERTY_STRING_CHECKPOINT_NAME   "com.tibco.tibdg.gridmetadata_checkpointname"

Property name for specifying a Checkpoint to be used when retrieving data grid and table metadata; string.

Specifying this property instructs the data grid to use the named checkpoint when retrieving metadata for the data grid or tables.

◆ TIBDG_INVALID_RESOURCE

#define TIBDG_INVALID_RESOURCE   (5002)

Error code returned when a resource needs to be recreated; property value constant.

If a Prepared Statement exists prior to a grid redistribution, a subsequent Execute Query may fail. In this case, the Prepared Statement needs to be closed and recreated before running any more Execute Query commands.

◆ TIBDG_ITERATOR_CONSISTENCY_GLOBAL_SNAPSHOT

#define TIBDG_ITERATOR_CONSISTENCY_GLOBAL_SNAPSHOT   "global_snapshot"

Global snapshot consistency; property value constant.

This constant is one possible value of the property TIBDG_ITERATOR_PROPERTY_STRING_CONSISTENCY in the method tibdgTable_CreateIterator.

This value will cause a global snapshot to be taken across all nodes in the grid, which will then be used when iterating through the results. A global snapshot will ensure no partially committed transactions that span multiple nodes are observed in the iterator results at the cost of needing to coordinate the global snapshot when creating the iterator.

◆ TIBDG_ITERATOR_CONSISTENCY_SNAPSHOT

#define TIBDG_ITERATOR_CONSISTENCY_SNAPSHOT   "snapshot"

Snapshot consistency; property value constant.

This constant is one possible value of the property TIBDG_ITERATOR_PROPERTY_STRING_CONSISTENCY in the method tibdgTable_CreateIterator.

This value will cause a snapshot to be taken at each node independently, which will then be used when iterating through the results. A snapshot taken at each node does not require waiting to create a global snapshot across the entire grid when creating the iterator but could result in a partially committed transaction that spanned multiple nodes being observed in the results.

#define TIBDG_ITERATOR_PROPERTY_DOUBLE_FETCH_TIMEOUT   "com.tibco.tibdg.fetch.timeout"

Property name for the iterator fetch timeout; double.

This value determines how long (in seconds) the application will wait for the next batch of rows before timing out. If this property is not supplied the current timeout for the parent Connection is used. If a value of zero is supplied then there will be no limit to how long the application will wait.

When creating an iterator, supply this property to tibdgTable_CreateIterator. This property can also be supplied to tibdgStatement_ExecuteQuery to override the value that was used when the statement was created.

◆ TIBDG_ITERATOR_PROPERTY_LONG_PREFETCH

#define TIBDG_ITERATOR_PROPERTY_LONG_PREFETCH   "com.tibco.tibdg.prefetch"

Property name for iterator prefetch; long.

When creating an iterator, supply this property to tibdgTable_CreateIterator. Its value determines the maximum number of rows that will be prefetched from the data grid. If not specified or a value <= 0 is specified, a default prefetch of 256 is used.

◆ TIBDG_ITERATOR_PROPERTY_STRING_CONSISTENCY

#define TIBDG_ITERATOR_PROPERTY_STRING_CONSISTENCY   "com.tibco.tibdg.consistency"

Property name for iterator consistency; string.

When creating an iterator, supply this property to tibdgTable_CreateIterator. Its value determines the consistency of the iterator and whether or not a global snapshot needs to be taken.

#define TIBDG_LISTENER_PROPERTY_STRING_EVENT_TYPE_LIST   "com.tibco.tibdg.listener.eventtypelist"

Property name for Listener event type list; string.

When creating a table listener, supply this property to tibdgTable_CreateListener. Its value should be a string containing a comma separated list of event types that can be used to configure the listener to only receive events of a specific type or types (ex: only expired and deleted). Only put, delete, and expired are currently supported as valid event types to use in the string. Error events will always be delivered. Use the utility function tibdgEventTypeList_ToString to construct the string from an array of event types.

◆ TIBDG_SESSION_PROPERTY_BOOLEAN_TRANSACTED

#define TIBDG_SESSION_PROPERTY_BOOLEAN_TRANSACTED   "com.tibco.tibdg.transacted"

Property name for a transacted session; boolean.

When creating a session, supply this property to tibdgConnection_CreateSession. The value true specifies that the created session will be transacted.

◆ TIBDG_SESSION_PROPERTY_STRING_CHECKPOINT_NAME

#define TIBDG_SESSION_PROPERTY_STRING_CHECKPOINT_NAME   "com.tibco.tibdg.checkpointname"

Property name for specifying a Checkpoint to be used for reads; string.

Specifying this property instructs the datagrid to use the named checkpoint as the data source for this session's read operations (gets, iterators, queries, or statements). Write operations (puts, deletes) do not support this property.

◆ TIBDG_SQL_CMD_ERROR

#define TIBDG_SQL_CMD_ERROR   (5110)

Error code returned when there is a generic error with a SQL command.

This error code will be returned when a generic SQL command error occurs during the processing of a SQL command in the data grid.

Function Documentation

◆ tibdg_Close()

TIBDG_API void tibdg_Close ( tibEx  e)

Cleanup ActiveSpaces.

This call terminates ActiveSpaces within your program, and reclaims related resources that tibdg_Open allocated and initialized.

Calls to tibdg_Close decrement the ActiveSpaces reference counter, but actually close terminate ActiveSpaces only when the counter reaches zero.

In each program, the number of calls to tibdg_Open() and tibdg_Close() must match.

Programs must not call tibdg_Close within an ActiveSpaces callback.

Programs must cleanup other ActiveSpaces objects before closing ActiveSpaces.

Parameters
eThe exception object captures information about failures.
Returns
void

◆ tibdg_Open()

TIBDG_API void tibdg_Open ( tibEx  e,
tibint32_t  compatible_version 
)

Initialize ActiveSpaces.

This call initializes ActiveSpaces within your program, including threads and global data structures.

The first time a program calls it, this call initializes ActiveSpaces. If the program (or a third-party package) calls it again, it increments a reference counter, but does not reinitialize ActiveSpaces. Calls to tibdg_Close decrement the ActiveSpaces reference counter, but actually terminate ActiveSpaces only when the counter reaches zero.

In each program, the number of calls to tibdg_Open() and tibdg_Close() must match.

Parameters
eThe exception object captures information about failures.
compatible_versionThe program must supply the constant TIBDG_COMPATIBILITY_VERSION.
Returns
void
