-DISPLAY ACCEL (DB2)
The DISPLAY ACCEL command displays information about accelerator servers.
Abbreviation: -DIS ACCEL
Environment
This command can be issued from a z/OS® console, a DSN session under TSO, a DB2I panel (DB2® COMMANDS), an IMS™ or CICS® terminal, or a program that uses the instrumentation facility interface (IFI).
Data sharing scope: Group or local, depending on the SCOPE option.
Authorization
- DISPLAY privilege
System DBADM authority
- SYSOPR authority
- SYSCTRL authority
- SYSADM authority
DB2 commands that are issued from a logged-on z/OS console or TSO SDSF can be checked by DB2 authorization by using primary and secondary authorization IDs.

Option descriptions
- (accelerator-name)
- The accelerator server name. This option limits the display to the specified accelerator servers.
- (*)
- Requests a list of all accelerator servers, whether the servers are currently in use or not. Specifying an asterisk (*) as the accelerator name indicates that the display must include all accelerator servers.
- DETAIL
- Displays additional information for one or more of the accelerator servers. If DETAIL is not specified, a basic summary report is produced.
- LIST
- Produces a list of accelerator servers that are currently in
use or that have been started. Valid values are:
( ACTIVE )
Restricts the list of accelerator servers to those that are currently
in use.
- (*)
- Requests a list of all accelerator servers, whether they are currently in use or not. An accelerator that has just been created appears in the list only if it has been started by using the START ACCEL command.
- SCOPE
- Specifies the scope of the command. In a non-data-sharing environment,
the option is ignored. Valid values are:
- ( LOCAL )
- Displays information only for the accelerator servers for the current data sharing member.
- (GROUP)
- Displays information for accelerator servers for all members of the data sharing group.
- MEMBER
- Restricts the display for the identified accelerator server to specific members of the data sharing group. The default behavior is to display accelerator servers for the local member. In a non-data-sharing environment, this option is ignored.
Output
Message DSNX830I indicates the beginning of the output of the command.
Examples
- Example 1: Displaying information about all accelerator servers for a data sharing group
- The following command displays information about all of the accelerator servers for all members
in a data sharing
group:

-DIS ACCEL(*) SCOPE(GROUP) LIST(*)
The output is similar to the following example:

- The following command displays detailed information about active accelerator servers ACCEL1 and
ACCEL2 for data sharing member DB1D:
-DIS ACCEL(ACCEL1,ACCEL2) DETAIL LIST(ACTIVE) SCOPE(LOCAL) MEMBER(DB1D)
The output that is displayed depends on the accelerators that you are using.
For example, the following output is displayed for IBM®
DB2 Analytics Accelerator for z/OS V5 and earlier:
