The EXECUTE POSTINSTALL statement is a utility directive and does not
specify a managed object.
See Also Section 6.1
EXECUTE ABORT
FILE
execute
postinstall "@pcsi$source:[sysupd]product_cleanup.com"
uses [sysupd]product_cleanup.com ;
|
In this example, the EXECUTE POSTINSTALL statement sets up a command procedure to run after the product is installed. The USES option specifies the file name of the command procedure that is deleted after use.
The EXECUTE POST_UNDO statement specifies commands to execute when one or more patch kits are uninstalled by executing the PRODUCT UNDO PATCH command. These commands are run after all directories, files, and modules are processed.
(command,...)
Indicates the commands that the utility passes to the command interpreter after uninstalling patch kits indicated in the recovery data set being processed.
INTERACTIVE
Allows communication between the user and the specified command or commands executing in a subprocess.USES (file,...)
Indicates the files required to execute the commands you specified in the command parameter. The files listed with the USES option are saved in the recovery data set. When the UNDO PATCH operation is executed, these files are moved to a temporary directory for processing and deleted after use.
The EXECUTE POST_UNDO statement specifies commands to execute when one or more patch kits are uninstalled by executing the PRODUCT UNDO PATCH command. These commands are run near the end of operation, after all directories, files, and modules are processed. This statement is useful for automatically running a command procedure to perform cleanup or restore the system environment after one or more patch or mandatory product updates have been removed.See Also Section 6.1You specify actions to perform by including one or more DCL command lines in the EXECUTE POST_UNDO statement. These commands are passed for execution to the DCL interpreter running in a subprocess. Enclose each action, whether specified as a single DCL command or a command procedure, in double quotes. If more than one action is given, use parentheses to enclose the list.
Enclosing the EXECUTE POST_UNDO statement in a scope group (consisting of SCOPE and END SCOPE statements) has no effect on the way EXECUTE POST_UNDO commands are processed.
If you want your commands to prompt the user and accept the user's input, specify the EXECUTE POST_UNDO statement with the INTERACTIVE option. The INTERACTIVE option causes all output from DCL to be displayed, unless you prevent it. In contrast, when the INTERACTIVE option is not specified, output generated by DCL commands is displayed only for lines that are interpreted as DCL messages; that is, those beginning with a percent sign (%) in column one.
If you need files for the EXECUTE POST_UNDO statement, you must specify each one of them with the USES option. Files listed with the USES option are placed in the recovery data set (the [PCSI$UNDO_001] directory tree) when the patch kit is installed and retrieved during the PRODUCT UNDO PATCH operation.
There are certain restrictions on the use of the EXECUTE POST_UNDO statements:
- They can be packaged in a product kit only if the product is of a patch or mandatory update type.
- Only one EXECUTE POST_UNDO statement is allowed per product.
The DCL commands supplied with the EXECUTE POST_UNDO statement are not executed during the product installation; they are merely registered in the patch recovery data set description file for use in the PRODUCT UNDO PATCH operation.
The EXECUTE POST_UNDO statement causes the POLYCENTER Software Installation utility to define logical names for use by the subprocess that executes the specified commands. The commands should use these logical names to reference files, as follows:
- PCSI$SOURCE is a subdirectory in the root format under the user's login directory that points to the location of the files specified by the USES option. This logical name is defined for the subprocess in which product-supplied commands execute.
- PCSI$DESTINATION is a root directory specification that points to the root directory where the patch or mandatory update product material was placed in the installation operation.
- PCSI$SCRATCH is a subdirectory under the user's login directory that commands can use for temporary working space. The utility automatically deletes this directory and any files placed in it at the end of the operation.
The EXECUTE POST_UNDO statement is a utility directive and does not specify a managed object.
execute post_undo "@PCSI$SOURCE:[SYSUPD]EXEC_POST_UNDO.COM"
uses [SYSUPD]EXEC_POST_UNDO.COM ;
|
In this example, the EXECUTE POST_UNDO statement sets up a command procedure to run after the patch kit files are removed from the system as a result of the PRODUCT UNDO PATCH command execution. The USES option specifies the file name of the command procedure that is deleted after use.
The EXECUTE PRECONFIGURE statement specifies commands to execute after the user has selected the product for installation or reconfiguration, but before the user is asked to select options for the product.
(command,...)
Indicates the commands that the utility passes to the command interpreter in the preconfiguration environment.
INTERACTIVE
Allows communication between the user and the specified command or commands executing in a subprocess.USES (file,...)
Indicates the files required to execute the commands you specified in the command parameter. Files for the EXECUTE PRECONFIGURE statement cannot be supplied by a separate FILE statement because EXECUTE PRECONFIGURE is processed before files are copied to the target disk.
The EXECUTE PRECONFIGURE statement specifies commands to execute after the user has selected the product for installation or reconfiguration, but before the user is asked to select options for the product. This statement is useful for automatically running a command procedure in preparation for installing your product. This command procedure is packaged in the kit and is run before the standard configuration dialog with the user begins. The EXECUTE PRECONFIGURE statement gives you the ability to do such things as probe the system environment, ask the user questions, and define logical names for use later in the processing of LOGICAL NAME functions. The ability to conditionally provide product material, or to perform other actions based on decisions made at the very start of the operation, is a powerful and flexible mechanism.
Note
If you want to use LOGICAL NAME functions, the logical names must be either defined by the action of EXECUTE PRECONFIGURE statements, or by the user before the installation or reconfiguration operation is initiated. The processing of an EXECUTE PRECONFIGURE statement cannot be conditionalized by including it within an IF group that is controlled by a LOGICAL NAME function. In such a case, the EXECUTE PRECONFIGURE statement is always executed.You specify actions to perform by including one or more DCL command lines in the EXECUTE PRECONFIGURE statement. These commands are passed for execution to the DCL interpreter running in a subprocess. Enclose each action, whether specified as a single DCL command or a command procedure, in double quotes. If more than one action is given, use parentheses to enclose the list.
Enclosing the EXECUTE PRECONFIGURE statement in a scope group (consisting of SCOPE and END SCOPE statements) has no effect on the way EXECUTE PRECONFIGURE commands are processed.
If you want your commands to prompt the user and accept the user's input, specify the EXECUTE PRECONFIGURE statement with the INTERACTIVE option. The INTERACTIVE option causes all output from DCL to be displayed, unless you prevent it. In contrast, when the INTERACTIVE option is not specified, output generated by DCL commands is displayed only for lines that are interpreted as DCL messages, that is, those beginning with a percent sign (%) in column one.
If you need files for the EXECUTE PRECONFIGURE statement, specify them in the USES option. Each file you specify with the USES option must be present in the product material.
Note that the USES option does not cause the listed files to be placed permanently in your file system. As soon as the installation operation completes, the files listed with the USES option are deleted.
The EXECUTE PRECONFIGURE statement causes the POLYCENTER Software Installation utility to define logical names for use by the subprocess that executes the specified commands. The commands should use these logical names to reference files, as follows:
- PCSI$SOURCE is a subdirectory in the root format under the user's login directory that points to the location of the files specified by the USES option. This logical name is defined for the subprocess in which product-supplied commands execute. It is not the same PCSI$SOURCE logical name that can be defined by a user, in the user's process, pointing to the location of a product kit.
- PCSI$DESTINATION is a root directory specification that points to the root directory for the current scope where product material will be placed.
- PCSI$SCRATCH is a subdirectory under the user's login directory that commands can use for temporary working space. The utility automatically deletes this directory and any files placed in it at the end of the operation.
