When SET IMS=NEW, you have access to adapter environmental commands with which you can change certain parameters that control your FOCUS session.
To distinguish them from FOCUS commands such as the SET IMS command, adapter environmental commands include an MVS or TSO environmental qualifier and the keyword IMS.
The syntax is
{MVS|TSO} IMS SET env_commandvalue
where:
Is an environmental command.
Is an acceptable value for the environmental command.
Although the commands are prefixed with the environmental qualifier TSO or MVS, the adapter, and not the operating system, handles them.
Note: The MVS and TSO environmental qualifiers are synonymous and can be used interchangeably in any z/OS environment (for example, TSO or batch).
From a TSO session or batch job, you invoke the DBCTL environment by issuing the following two commands in the order shown
{MVS|TSO} IMS SET IMSPZP {xx|00}
{MVS|TSO} IMS SET DBCTL {ON|OFF}
where:
Sets the two-character suffix for the DRA Startup Table, chosen during installation (see Installation Instructions Instructions). If you do not issue this command, the suffix defaults to 00.
Turns on the DBCTL environment.
Turns off the DBCTL environment. OFF is the default in a TSO session.
If you did not create an Access File to automatically select the PSB for your request (see Creating FOCUS Descriptions) or to change the selected PSB, issue the following command
{MVS|TSO} IMS SET PSB psbname
where:
Is the name of the FOCPSB library member to use. This name must be identical to the name of the actual PSB that IMS will access. If the member does not exist, the following error message is generated:
(FOC4261) FOCPSB MEMBER NOT FOUND: psbname
Note:
(FOC4295) ACCESS POINTS TO DIFFERENT PSBS IN JOIN
If SET IMS=NEW, the default, you can issue the IMS SET ? command at any time during your session to display Interface defaults and current settings.
The syntax is:
{MVS|TSO} IMS SET ?
For example:
> > TSO IMS SET DBCTL ON > > TSO IMS SET IMSPZP 05 > > TSO IMS SET PSB TSTPSB01 > > TSO IMS SET ? (FOC4280) IMSMODE : DBCTL (FOC4281) PSB : TSTPSB01 (FOC4282) IMSSEC : OFF (FOC4283) IMSCLASS : (FOC4284) IMSPZP : 05
