Identifies the DMCL with which the disk journal file is associated. Dmcl-name must name an existing DMCL defined to the dictionary. If you don't specify a DMCL name, you must establish a current DMCL as described in 7.3.3, "Entity Currency" earlier in this chapter.
Specifies the name of the journal file. Journal-file-name must be a 1- through 18-character name that follows the conventions described in 7.3, "Naming Conventions".
Journal-file-name must be unique among the disk and archive journal file names within the DMCL definition.
Specifies the number of blocks in the journal file. This clause is required on a CREATE statement. Block-count is an integer in the range 9 through 2,147,483,647.
Specifies an external file name. Every external file name in a DMCL definition must be unique. In z/VSE without DYNAM/D, an external file name must be specified. In other environments, if the external file name is not specified, a data set name or VM virtual address must be specified.
(z/OS and z/VM systems only) Specifies the external name for the file. ddname must be a 1- through 8-character value that follows operating system conventions for ddnames.
(z/VSE systems only) Specifies the external name for the file. filename must be a 1- through 7-character value that follows operating system conventions for file names.
Sets the external file name to blanks. It is equivalent to not specifying an external file name for a file. This option is not valid under z/VSE unless DYNAM/D is being used.
Identifies the access method for the journal file as BDAM, or DAM. BDAM is a synonym for NONVSAM. NONVSAM is the default.
The access method you specify must be the same for all disk journal files associated with the DMCL.
Identifies the access method for the journal file as VSAM. The access method you specify must be the same for all disk journal files associated with the DMCL.
Specifies the name of the data set to be used when dynamically allocating the journal file for z/OS, z/VSE, and OS-format data sets under z/VM.
data-set-name must conform to host operating system rules for forming data set names.
A data-set-name that includes embedded periods must be enclosed in single or double quotation marks.
Under z/VM, the DSNAME parameter or VM VIRTUAL ADDRESS and USERID parameters, or both can be specified.
Sets the data set name to blanks. This is equivalent to not specifying a data set name for a file.
(z/OS and z/VM systems only) Specifies the disposition to be assigned when the file is dynamically allocated.
Indicates that the data set used for the file is available to a DC/UCF system and multiple local mode applications at a time.
Under z/VM, DISP SHR causes a link with an access mode of multiple read (MR).
SHR is the default when you do not include the DISP parameter in a CREATE JOURNAL FILE statement.
(z/VM systems only) Specifies the virtual address of the minidisk used for the journal file. virtual-address is a hexadecimal value in the range X'01' to X'FFFF'.
Sets the virtual address to blanks. On CREATE statements, this is equivalent to not specifying a virtual address for a file. On ALTER statements, it removes any previous virtual address specification for the file.
(z/VM systems only) Identifies the owner of the minidisk used for the journal file. vm-user-id is a 1- to 8-character value.
A user ID for an OS-format data set must be specified. The user ID is optional for CMS-format files.
If a user ID is not specified for a CMS-format file, CA IDMS assumes that the owner of the minidisk is the user ID of the virtual machine in which it is running.
On CREATE statements, this is equivalent to not specifying a minidisk owner for a file. On ALTER statements, removes any previous minidisk owner specification for the file.
Displays or punches details about the disk journal.
Displays or punches:
Displays or punches all information about the disk journal. ALL is the default action for a DISPLAY or PUNCH verb.
Displays or punches the name of the disk journal.
