Use the following operator command to load global variables from a global member (or an IOA variable database) into Control‑O memory:
F CONTROLO,LOADGLOBAL[=memname] |
where memname indicates the global members (or variable databases) to be loaded. The table lists the valid values.
Table 192 Values for Loading Global Variables
Value |
Description |
|---|---|
name |
Name of a specific global member (or variable database) to load. |
ALL |
Load all global members (and variable databases) listed in the DAGLBLST concatenation. |
If no memname value is specified with a LOADGLOBAL command, only member $GLOBAL (that is, the default global member) is loaded.
WARNING: Issuing LOADGLOBAL is hazardous in a live system!
Changes to the databases (for example, through %%SET in JCL, DO SET, or SET VAR) are accumulated in memory and are written to disk during the next WRITEGLOBAL command (performed automatically for the IOAVAR database at set intervals). Between the changes and the WRITEGLOBAL command is a time window in which the LOADGLOBAL command will delete the changes. BMC recommends only using the LOADGLOBAL command for updating a database during a scheduled downtime.
