This database file includes high-level data link control (HDLC) file entries.
Statistics are kept on a line basis for the fields in the HDLC file.
| Field Name | Description | Attribute |
|---|---|---|
| INTNUM | Interval number: the nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command. | PD (5,0) |
| DTETIM | Interval date (yymmdd) and time (hhmmss): The date and time of the sample interval. | C (12) |
| INTSEC | Elapsed interval seconds: The number of seconds since the last sample interval. | PD (7,0) |
| IOPRN | IOP resource name. | C (10) |
| SHIOP | Reserved | C (1) |
| SHTYPE | The resource type of the IOP or adapter represented by this record. | C (4) |
| SHLND | Line description: The name of the description for this line. | C (10) |
| SHLSP | Line speed: The speed of the line in bits per second (bps.) | PD (11,0) |
| SHBTRN | Bytes transmitted: The number of bytes transmitted including bytes transmitted again. | PD (11,0) |
| SHBRCV | Bytes received: The number of bytes received including all bytes in frames that had any kind of error. | PD (11,0) |
| SHPRCL | Protocol type: S for SDLC. | C (1) |
| SHFTRN | Number of frames transmitted (I, supervisory, and frames not numbered) excluding frames transmitted again. | PD (11,0) |
| SHIFTR | Number of I-frames transmitted excluding I-frames transmitted again. | PD (11,0) |
| SHIFRT | Number of I-frames transmitted again. | PD (11,0) |
| SHFRT | Number of I, supervisory, and frames not numbered transmitted again. | PD (11,0) |
| SHEFFR | Error-free frames received: The number of I, supervisory, and frames not numbered received without error (whether or not they were transmitted again from the remote side.) | PD (11,0) |
| SHEFIR | Error-free I-frames received: The number of I-frames received without error (whether or not they were transmitted again from the remote side.) | PD (11,0) |
| SHFRIE | Frames received in error: The number of I, supervisory, and frames not numbered received in error. There are three error possibilities: (1) a supervisory or I-frame was received with an Nr count that is requesting retransmission of a frame, (2) an I-frame was received with an Ns count that indicates that frames were missed, (3) a frame is received with one of the following errors: a frame check sequence error, an abnormal end, a receive overrun, or a frame truncated error. | PD (11,0) |
| SHIFR | Frames received that are not valid: The number of not valid frames received. These are frames received with either: (1) short frame error-frame is less than 32 bits or (2) residue error-frame is not on a byte boundary. | PD (11,0) |
| SHRRFT | Number of receive ready supervisory frames transmitted. | PD (11,0) |
| SHRRFR | Number of receive ready supervisory frames received. | PD (11,0) |
| SHRNRT | Number of receive not ready supervisory frames transmitted. | PD (11,0) |
| SHRNRR | Number of receive not ready supervisory frames received. | PD (11,0) |
| SHLNKR | Data link resets: The number of times a set normal response mode (SNRM) was received when the station was already in normal response mode. | PD (11,0) |
| SHCPT | The length of time (in tenths of seconds) that the system waits for the response to a poll while in normal disconnect mode before polling the next station. | PD (3,0) |
