Loading AutoEdit Variable Databases

Use one of the following operator commands to load an AutoEdit database into memory:

• If Control‑O is not installed, use

  F CTMCMEM,LOADGLOBAL[=dbname]

• If Control‑O is installed, use

  F CONTROLO,LOADGLOBAL[=dbname]

  where dbname indicates the databases to be loaded. Valid values:

  • name - The name of a specific database to load.
  • ALL - All databases listed in the concatenation referenced by DD statement DAGLBLST are loaded. If Control‑O is being used, Control‑O members are loaded.
  • <none> - Only the default member, $GLOBAL, 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.
