The CICSplex MVS TCB Global Details attribute group reports on data related to start time, storage usage, and CPU time of the CICS Task Control Blocks (TCBs). This is retrieved using the COLLECT STATISTICS DISPATCHER command.
Address Space CPU Time Is the total CPU time (accurate to three decimal places) accumulated by this CICS address space. This is obtained from the z/OS Address Space Control Block field ASCBEJST. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example, 1200.567. If you are using variable substitution, the value in this example would display as 1200567.
Address Space SRB Time Is the total SRB time (accurate to three decimal places) accumulated by this CICS address space so far. This is obtained from the z/OS Address Space Control Block field ASCBSRBT. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example, 1200.567. If you are using variable substitution, the value in this example would display as 1200567.
CICS Region Name Is the job name or modify ID of the CICS region that is being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case-sensitive. CICS region names are always in uppercase characters.
CICS Start Time Is the time at which the CICS dispatcher started. This value is used as an approximate time at which CICS started. The DFHSTUP report expresses this time as hours:minutes:seconds.decimals; however, the DSECT field contains the time as a store clock (STCK) value in GMT. This information is obtained from the DISPATCHER statistics record DFHDSGDS and the DSGSTART field.
CICS TCB Count Is the number of TCBs currently present in the CICS address space that are part of CICS, that is controlled by the CICS Dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_CICSTCB_COUNT.
CICS TCB CPU Time Is the amount of CPU time (accurate to three decimal places) that has been used by the TCBs currently present in the CICS address space that are controlled by the CICS Dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_CICSTCB_CPUTIME. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example, 1200.567. If you are using variable substitution, the value in this example would display as 1200567.
CICS TCB Storage Above Is the amount of private storage above the 16M line currently allocated to TCBs currently present in the CICS address space that are part of CICS, that is controlled by the CICS Dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_CICSTCB_STG_ABOVE.
CICS TCB Storage Below Is the amount of private storage below the 16M line currently allocated to TCBs currently present in the CICS address space that are part of CICS, that is, controlled by the CICS Dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_CICSTCB_STG_BELOW.
CPU Time since reset Is the CPU time (accurate to three decimal places) accumulated by this CICS address space since the last statistics reset. This information is obtained from the DFHDSGDS DISPATCHER statistics record in the DSGEJST field. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example 1200.567. If you are using variable substitution, the value in this example would display as 1200567.
Current non-CICS TCB count Is the number of TCBs currently present in the CICS address space that are not part of CICS, that is, not controlled by the CICS dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_NONCICSTCB_COUNT.
Non-CICS TCB CPU Time Is the amount of CPU time (accurate to three decimal places) that has been used by the TCBs currently present in the CICS address space that are NOT controlled by the CICS dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_NONCICSTCB_CPUTIME. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example, 1200.567. If you are using variable substitution, the value in this example would display as 1200567.
Non-CICS TCB Kbytes above 16M Is the amount of private storage above the 16M line currently allocated to TCBs currently present in the CICS address space that are NOT part of CICS, that is not controlled by the CICS Dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_NONCICSTCB_STG_ABOVE.
Non-CICS TCB Kbytes below 16M Is the amount of private storage below the 16M line currently allocated to TCBs currently present in the CICS address space that are NOT part of CICS, that is not controlled by the CICS Dispatcher. This information is obtained from the z/OS TCB statistics record DFHDSTDS, field DSTDS_NONCICSTCB_STG_BELOW.
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.
SRB Time since reset Is the SRB time (accurate to three decimal places) accumulated by this CICS address space since the last statistics reset. This information is obtained from the DFHDSGDS DISPATCHER statistics record, in the DSGSRBT field. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example 1200.567. If you are using variable substitution, the value in this example would display as 1200567.
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 four characters, and case-sensitive. z/OS System IDs are always in uppercase characters.
