CICS TS V5.5 Performance data in group DFHCICS.  Numeric identifier, type, size and a brief description are included.  The information is extracted from IBM website. Here is the lnk: https://www.ibm.com/docs/en/cics-ts/5.5?topic=fields-performance-data-in-group-dfhcics

351 (TYPE-C, 'OADID', 64 BYTES)
The adapter identifier added to the origin data by the adapter. This field is blank if the task was not started by using an adapter, or if it was and the adapter did not set this value.
352 (TYPE-C, 'OADATA1', 64 BYTES)
The data added to the origin data by the adapter. This field is blank if the task was not started by using an adapter, or if it was and the adapter did not set this value.
353 (TYPE-C, 'OADATA2', 64 BYTES)
The data added to the origin data by using the adapter. This field is blank if the task was not started by using an adapter, or if it was and the adapter did not set this value.
354 (TYPE-C, 'OADATA3', 64 BYTES)
The data added to the origin data by the adapter. This field is blank if the task was not started by using an adapter, or if it was and the adapter did not set this value.
359 (TYPE-C 'ONETWKID', 8 BYTES
The network identifier from which this work request (transaction) originated.
360 (TYPE-C, 'OAPPLID', 8 BYTES)
The APPLID of the CICS region in which this work request (transaction) originated; for example, the region in which the CWXN task ran.
361 (TYPE-T, 'OSTART', 8 BYTES)
The time at which the originating task, for example the CWXN task, was started.
362 (TYPE-P, 'OTRANNUM', 4 BYTES)
The number of the originating task; for example, the CWXN task.
363 (TYPE-C, 'OTRAN', 4 BYTES)
The transaction ID (TRANSID) of the originating task; for example, the CWXN task.
364 (TYPE-C, 'OUSERID', 8 BYTES)
The originating Userid-2 or Userid-1, for example from CWBA, depending on the originating task.
365 (TYPE-C, 'OUSERCOR', 64 BYTES)
The originating user correlator.
366 (TYPE-C, 'OTCPSVCE', 8 BYTES)
The name of the originating TCPIPSERVICE.
367 (TYPE-A, 'OPORTNUM', 4 BYTES)
The port number used by the originating TCPIPSERVICE.
369 (TYPE-A, 'OCLIPORT', 4 BYTES)
The TCP/IP port number of the originating client or Telnet client.
370 (TYPE-A, 'OTRANFLG', 8 BYTES)
Originating transaction flags, a string of 64 bits used for signaling transaction definition and status information:
371 (TYPE-C, 'OFCTYNME', 8 BYTES)
The facility name of the originating transaction. If the originating transaction is not associated with a facility, this field is null. The transaction facility type, if any, can be identified using byte 0 of the originating transaction flags, OTRANFLG (370), field.
372 (TYPE-C, 'OCLIPADR', 40 BYTES)
The IP address of the originating client or Telnet client.
373 (TYPE-C, 'PHNTWKID', 8 BYTES)
The network identifier of the CICS system of an immediately previous task in another CICS system with which this task is associated. See Previous hop data characteristics for more information about previous hop data.
374 (TYPE-C, 'PHAPPLID', 8 BYTES)
The APPLID from previous hop data. This is the APPLID of the CICS system of a previous task in another CICS system with which this task is associated. See Previous hop data characteristics for more information about previous hop data.
375 (TYPE-T, 'PHSTART', 8 BYTES)
The start time of the immediately previous task in another CICS system with which this task is associated. See Previous hop data characteristics for more information about previous hop data.
376 (TYPE-P, 'PHTRANNO', 4 BYTES)
The task number of the immediately previous task in another CICS system with which this task is associated. See Previous hop data characteristics for more information about previous hop data.
377 (TYPE-C, 'PHTRAN', 4 BYTES)
The transaction ID (TRANSID) of the immediately previous task in another CICS system with which this task is associated. See Previous hop data characteristics for more information about previous hop data.
378 (TYPE-A, 'PHCOUNT', 4 BYTES)
The number of times there has been a request from one CICS system to another CICS system to initiate a task with which this task is associated.
480 (TYPE-T, 'PTSTART', 8 BYTES)
The start time of the immediately previous or parent task in the same CICS system with which the task is associated. See Previous transaction data characteristics for more information about previous transaction data.
481 (TYPE-P, 'PTTRANNO', 4 BYTES)
The task number of the immediately previous or parent task in the same CICS system with which the task is associated. See Previous transaction data characteristics for more information about previous transaction data.
482 (TYPE-C, 'PTTRAN', 4 BYTES)
The transaction ID (TRANSID) of the immediately previous or parent task in the same CICS system with which the task is associated. See Previous transaction data characteristics for more information about previous transaction data.
483 (TYPE-A, 'PTCOUNT', 4 BYTES)
The number of times there has been a request from one task to initiate another task in the same CICS system with which this task is associated, such as by a RUN TRANSID or START command. This is effectively the task depth in the local region when using the RUN TRANSID command, or the START command when a new point of origin is not created. See Previous transaction data characteristics for more information about previous transaction data.
