The CICSplex Transaction I/O Waits Analysis attributes report a breakdown of the time the transaction waited as a result of I/O operations. Use the CICSplex Transaction I/O Waits Analysis attributes to determine which activity is contributing excessively to the transaction's suspend time or overall elapsed time.
CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS image has a unique name. This name is an alphanumeric string, with a maximum of 8 characters, and case-sensitive. CICS region names are always in uppercase characters.
FEPI I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for all FEPI I/O services.
File I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for file I/O to complete.
Inter -Region (MRO) Indicates the amount of time, in thousandths of a second, that the transaction waited for MRO requests to another CICS region to complete.
Journal (z/OS Logger) Indicates the amount of time, in thousandths of a second, that the transaction waited for journal or z/OS logger I/O requests to complete.
LU 6.1 Terminal I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for control at this end of an LU 6.1 link.
LU 6.2 Terminal I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for control at this end of an LU 6.2 link.
Origin Node Is the combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.
When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.
RLS File I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for RLS file I/O to complete.
Shared TS I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for asynchronous shared temporary storage requests to complete.
Socket I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for socket I/O activities to complete.
System ID Indicates the four-character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum 4 characters, and case-sensitive. z/OS System IDs are always in uppercase characters.
Task Number Is the number sequentially assigned by CICS to uniquely identify each task.
Temporary Storage I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for VSAM temporary storage I/O activities to complete.
Terminal I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for user input from the terminal.
Transaction ID Is the four-character name of the transaction.
Transient Data I/O Wait Indicates the amount of time, in thousandths of a second, that the transaction waited for VSAM transient data I/O activities to complete.
