IMS DB system commands supported by
Enterprise Server, which are a subset of all IMS DB commands.
/DIS
Syntax:
/DIS[PLAY] DB ALL | database1 [database2] ...
Syntax Rules:
This returns the current status of each of the named databases.
1 to 16 databases can be specified or the “ALL” parameter.
ES-IMS only returns database status for those databases it knows about. ES-IMS accesses databases as they are accessed by application programs and system commands, so the list of "known" databases grows dynamically.
Database statuses::
UNKNOWN - The database name is not valid. There is no ACB defined for this DB.
NOTOPEN - The database is defined but has not been accessed.
OPEN - The database is currently being accessed by an application program.
CLOSED - The database has been opened but is not currently open.
STOPPED - The database is stopped and not available to MPP, BMP or CICS-DLI programs.
/STO
Syntax:
/STO[P] DB database1 [database2] ...
Sytax Rules:
The STOP command stops a database or a list of databases.
When a database is stopped, it is not accessible from MPP, BMP or CICS-DLI programs. The database is only accessible from IMSDBU or batch DLI programs.
This command is run synchronously. It will suspend until the database is closed and stopped.
/STA
Syntax:
/STA[RT] DB database1 [database2] ...
Syntax Rules:
The START command starts a database or a list of databases.
Use the START command to make the database available to online, BMP and CICS-DLI programs.
