H.4.2.13 RMS Class Record

The RMS class record contains data describing Record Management Services for specified files. The RMS class record has a record type of 20. Use the following formula to calculate the record size (the formula calculates the size by adding the size of the class header, the class prefix, and the data blocks contained in the record):

13 + 8 + (273 * MNR_CMP$L_ELTCT)

Figure H-20 illustrates the format of the RMS class record. Table H-20 describes the fields in the data block for the RMS class record.

H.4.2.14 SCS Class Record

The SCS class record contains data describing SCS (System Communications Services) activity for all SCS connections in the system, on a per-node basis. The SCS class record has a record type of 15; its size depends on the number of nodes being monitored. The size, in bytes, is calculated by adding the size of the class header, the class prefix, and the data blocks contained in the record. This is shown in the following formula:

13 + 8 + (56 * the value of MNR_CMP$L_ELTCT)
