Use the Coupling Facility attributes to create table views, charts, and situations that monitor coupling facility characteristics.
Connected Jobname The job name connected to a coupling facility structure. Valid format consists of up to eight alphanumeric characters. Example: IMS510AI
Connection Name The name of the connection between an IMS coupling facility and an MVS address space. Valid format consists of up to 16 alphanumeric characters.
Connection Status The status of the connection between an IMS coupling facility member (IRLM subsystem) and group. Valid values include ACTIVE, CONNECT, DISCONN, FAIL-PER, and FAILING.
Coupling Facility Name The name of an IMS coupling facility. Valid format consists of up to eight alphanumeric characters.
Elements Allocated Number of Data Elements allocated for data sharing cache and shared queues list structures only. Valid format is an integer.
Elements Used Number of Data Elements in use for data sharing cache and shared queues list structures only. Valid format is an integer.
Elements Used Percent The number of Elements in use divided by the number of Elements allocated. Applicable to Coupling Facility data sharing cache and shared queues list structures only. Valid format is an integer.
EMCs Allocated Number of EMCs allocated for a shared queues list structure only. Valid format is an integer.
EMCs Used Number of EMCs in use for a shared queues list structure only. Valid format is an integer.
EMCs Used Percent EMCs Used Percent is the number of EMCs in use divided by the number of EMCs allocated. Applicable to Coupling Facility shared queues list structures only. Valid format is an integer.
False Contention The number of contentions that the IRLM thought were competing for the same database resource. Valid format is an integer. Example: 893. An IRLM subsystem identifies a contention, but the IRLM grants a lock to a contending IRLM subsystem because the contending IRLM is requesting access to a different segment in the database.
False Contention Rate The number of false contentions divided by the number of seconds during the collection interval. Valid format is an integer.
Global Contention The total number of contentions competing for the same database resource. Valid format is an integer.
Global Contention Rate The number of global contentions divided by the number of seconds during the collection interval. Valid format is an integer.
Group Name The name of a data sharing or shared queues group. Valid format consists of up to eight alphanumeric characters, such as this example: IRLMD1.
Group Type Indicates the type of group, including DataSharingGroup and SharedQueuesGroup.
IMSID The IMS Subsystem identifier. Valid format consists of up to four alphanumeric characters, such as this example: I61A.
LockTable Delay Count For Coupling Facility data sharing lock structures, the number of requests that experienced a delay in servicing. Valid format is an integer.
LockTable Delay Count Extended Precision For Coupling Facility data sharing lock structures, the number of requests that experienced a delay in servicing (64 bit). Valid format is an integer.
LockTable Delay Percent For Coupling Facility data sharing lock structures, the percentage of requests issued that experienced a delay in servicing. Valid format is an integer.
LockTable Entries Allocated For Coupling Facility data sharing lock structures, the number of Entries allocated in the lock table portion of the lock structure. Valid format is an integer.
LockTable Entries Used For Coupling Facility data sharing lock structures, the number of Entries in use in the lock table portion of the lock structure. Valid format is an integer.
LockTable Entries Used Percent For Coupling Facility data sharing lock structures, the Lock Table Used Percent is the number of Lock Table Entries in use divided by the number of Lock Table Entries Allocated. Valid format is an integer.
LockTable Request Count For Coupling Facility data sharing lock structures, the total number of requests (IXLLOCK, IXLRT, and IXLSYNCH) issued for the lock structure. Valid format is an integer.
LockTable Request Count Extended Precision For Coupling Facility data sharing lock structures, the total number of requests (IXLLOCK, IXLRT, and IXLSYNCH) issued for the lock structure (64 bit). Valid format is an integer.
MVS System The MVS System Management Facility (SMF) identifier. Valid format consists of up to four alphanumeric characters. Example: SP11.
Originating System Identifier Fully identifies the originating IMS subsystem. Valid format consists of up to 32 alphanumeric characters. Example: I91A:SP22:IMS
Record Entries Allocated The total number of entries an IMS system has allocated for a coupling facility structure. Valid format is an integer.
Record Entries Used The total number of entries IRLM is currently using for a coupling facility structure. Valid format is an integer.
Record EntriesUsed Percent The number of record entries used divided by the number of record entries allocated. Valid format is an integer.
Structure Name The name of an IMS coupling facility structure. Valid format consists of up to 16 alphanumeric characters. Example: IRLMLT1.
Structure Size The size of an IMS coupling facility structure. Valid format is an integer.
Structure Type The type of IMS coupling facility structure. Valid values include CACHE, LIST, and LOCK.
Sysplex Identifier Indicates the originating sysplex for this request. Valid format consists of up to eight alphanumeric characters.
Timestamp The date and time when the monitoring agent retrieved the data. This attribute is intended for logging and reporting data collection times rather than for creating situations. To specify a time of day for monitoring, use attributes from the Universal Time or Local Time groups. See the Tivoli Enterprise Portal help for instructions on specifying timestamp attributes in situations and queries.
