pattern_type (wildcard_receiver) <-

: The type of expression UM uses to compare wildcard receiver patterns to new topics seen in topic advertisements or responses to wildcard receiver queries.

Attention: As of UM Version 6.1, wildcard receivers must use PCRE expressions.

Scope:	wildcard_receiver
Type:	int
When to Set:	Can only be set during object initialization.

Description

"pcre"

LBM_WILDCARD_RCV_PATTERN_TYPE_PCRE

The pattern is a regular expression usable by PCRE (Perl Compatible Regular Expressions) library. Default for all.

"regex"
DEPRECATED in UM Version 6.1.

LBM_WILDCARD_RCV_PATTERN_TYPE_REGEX

The pattern is a regular expression usable by POSIX Extended Regular Expressions.

"appcb"
DEPRECATED in UM Version 6.1.

LBM_WILDCARD_RCV_PATTERN_TYPE_APP_CB

The wildcard receiver ignores the pattern and calls an application callback set by the pattern_callback (wildcard_receiver) option.

receiver_create_callback (wildcard_receiver) <-

: Callback function (and associated client data pointer) that is called when a receiver is about to be created for a topic which matched a wildcard receiver pattern.

: This callback is called by the context thread and can not use an event queue. Therefore the callback function used should not block or it will delay reception of latency-sensitive messages.

: The callback function should always return 0.

Scope:	wildcard_receiver
Type:	lbm_wildcard_rcv_create_func_t
Default value:	NULL
When to Set:	Can only be set during object initialization.
Config File:	Cannot be set from an UM configuration file.
Version:	This option was implemented in LBM 3.4/UME 2.1.

receiver_delete_callback (wildcard_receiver) <-

: Callback function (and associated client data pointer) that is called when a receiver is about to be deleted.

: This callback is called by the context thread and can not use an event queue. Therefore the callback function used should not block or it will delay reception of latency-sensitive messages.

: The callback function should always return 0.

Scope:	wildcard_receiver
Type:	lbm_wildcard_rcv_delete_func_t
Default value:	NULL
When to Set:	Can only be set during object initialization.
Config File:	Cannot be set from an UM configuration file.
Version:	This option was implemented in LBM 3.4/UME 2.1.

resolver_no_source_linger_timeout (wildcard_receiver) <-

: This sets the linger timeout value before a topic with no sources is removed and cleaned up.

: Since wildcard receivers set the resolution_no_source_notification_threshold (receiver) to 10, the linger timer starts after the wildcard receiver sends 10 queries and subsequently receives a no-source notification.

Scope:	wildcard_receiver
Type:	lbm_ulong_t
Units:	milliseconds
Default value:	1000 (1 second)
When to Set:	Can only be set during object initialization.

resolver_query_maximum_interval (wildcard_receiver) <-

: The longest - and last - interval in wildcard receiver topic querying.

: This option has an effective minimum of 30 ms. See UDP-Based Resolver Operation Options.

: A value of 0 disables wildcard receiver topic querying. Informatica recommends against disabling all queries; see Disabling Aspects of Topic Resolution.

Scope:	wildcard_receiver
Type:	lbm_ulong_t
Units:	milliseconds
Default value:	1000 (1 second)
When to Set:	Can only be set during object initialization.
Version:	This option was implemented in LBM 4.0

resolver_query_minimum_duration (wildcard_receiver) <-

: The duration of wildcard queries in wildcard receiver topic querying.

: Only PCRE and regex pattern types can use wildcard queries. A value of 0 guarantees that wildcard receiver topic querying never completes.

Scope:	wildcard_receiver
Type:	lbm_ulong_t
Units:	seconds
Default value:	60 (1 minute)
When to Set:	Can only be set during object initialization.
Version:	This option was implemented in LBM 4.0

resolver_query_minimum_interval (wildcard_receiver) <-

: Interval between the first topic query sent upon creation of the wildcard receiver and the second query sent by the receiver.

: This option has an effective minimum of 30 ms. See UDP-Based Resolver Operation Options.

: A value of 0 disables wildcard receiver topic querying. Informatica recommends against disabling all queries; see Disabling Aspects of Topic Resolution.

Scope:	wildcard_receiver
Type:	lbm_ulong_t
Units:	milliseconds
Default value:	50 (0.05 seconds)
When to Set:	Can only be set during object initialization.
Version:	This option was implemented in LBM 4.0

resolver_wildcard_queries_per_second (context) <-

: Maximum number of queries sent within a one second period during wildcard receiver topic querying.

: A value of 0 means that queries for the wildcard topic are not limited to a maximum number of queries per second.

: Note that the topic's queries are still subject to being rate limited by resolver_wildcard_query_bps (context).

: Refer to Rate Controls for additional information.

Scope:	context
Type:	lbm_ulong_t
Units:	advertisements
Default value:	0
When to Set:	Can only be set during object initialization.
Version:	This option was implemented in LBM 4.0

resolver_wildcard_query_bps (context) <-

: Maximum query rate during wildcard receiver topic querying.

: A value of 0 means that queries for the wildcard topic are not limited to a maximum number of bits per second. Note that the topic's queries are still subject to being rate limited by resolver_wildcard_queries_per_second (context).

: Refer to Rate Controls for additional information.

Scope:	context
Type:	lbm_uint64_t
Units:	bits per second
Default value:	1000000
When to Set:	Can only be set during object initialization.
Version:	This option was implemented in LBM 4.0

resolver_wildcard_receiver_map_tablesz (context) <-

: The size of the hash table used for storing wildcard receiver patterns.

: A value of 0 disables caching wildcard receiver patterns. This value should be a prime number.

Scope:	context
Type:	size_t
Units:	map entries
Default value:	10273
When to Set:	Can only be set during object initialization.
