Host Environment Commands › ADDRESS MIM Command › ENV Function › Variable ENV.n

Variable ENV.n

The ENV function creates the ENV.n variable for every active CA MIM address space. The ENV.0 variable contains the count of these CA MIM subsystems. For example, values about CA MIM subsystems are in ENV.1 through ENV.x where x is equal to ENV.0. The index numbers do not have leading zeros.

Every ENV.n stem has the ENV.n.SYS.0 variable, which contains the number (m) of systems connected to MIM.n. These systems are in ENV.n.SYS.1 through m. In the same manner every ENV.n stem has also ENV.n.FAC.0 variable with number m of facilities. These are in ENV.n.SYS.1 through m.

In all cases, leading zeroes and multiple blanks are suppressed in the data fields within each variable. All components within the created variables comply with REXX standards, and as such are variable length, blank separated, and easily parsed into individual REXX names. If no data is available for a particular field, it will contain a single asterisk. Also, any blanks within a field will be replaced by an underscore.

The following lists the sequence of fields for ENV.n variable:

1

Contains the two-character CA MIM block version identifier.

2

Contains the CA MIM complex name, which can be up to eight characters.

3

Contains the jobname, which can be up to eight characters.

4

Contains the SSI command prefix, which can be up to eight characters.

5

Contains the CA MIM product version, which can be up to eight characters.

6

Contains the CA MIM product maintenance level, which can be up to eight characters.

7

Contains the CA MIM compatibility level, which can be up to eight characters.

8

Contains the CA MIM subsystem name, which can be up to four characters.

9

Contains the Address space ID (ASID), specified in four hexadecimal characters.

10

Contains the number of active facilities specified as a four-character numeric value.

11

Contains the Facility Mask specified as an eight-bit mask translated to a single eight-character word. Characters are Y or N corresponding to on or off. The facilities correspond to the character positions as follows:

15

Contains the heart-beat time. The time-of-day clock value consists of 16 hexadecimal characters.

16

Contains the heart-beat status, which consists of the following possible values:

• NORMAL
• WARNING
• PROBLEM

17

Contains the heart-beat reason, which can have up to 32 characters. The heart-beat reason is documented in the CA MIM Programming Guide section CA MIM Health Check State Management.

18

19

Contains the CA OPS/MVS operational state, which can have the following possible values:

• STARTING
• UP
• STOPPING
• DOWN
