Global storage GETBLK vector (X'000100030004')

The format of global storage GETBLK vector is shown in Table 1. One global storage GETBLK vector is built for each GETBLK subpool that exists in VTAM® per request for global storage usage data. A GETBLK subpool is identified by its pool ID and buffer size. A given GETBLK pool might also be made up of multiple subpools, each of which have a different buffer size.
Table 1. Global storage GETBLK vector
Byte Type Description
8–15 EBCDIC, left-adjusted Pool name
16–19 binary Subpool buffer length
20–21 binary Number of buffers per page
22–25 binary Page size
26–29 binary Number of bytes in use in subpool1
30–33 binary
resettable		 Maximum number of bytes in use in subpool since last reset1
34–41 binary
resettable		 Timestamp for maximum number of bytes in use in subpool since last reset
42–45 binary Number of bytes allocated in subpool1
46–49 binary
resettable		 Maximum number of bytes allocated in subpool since last reset1
50–57 binary
resettable		 Timestamp for maximum number of bytes allocated in subpool since last reset
Note:
  1. If bit 0 is off, these fields contain a byte count. If bit 0 is on, bits 1-31 contain a megabyte count.
