Open System Services Installation Guide (H06.16+, J06.05+)

NOTE: The examples in this procedure show the prompts that OSSREMOV displays but not the

status messages. Example 9 (page 37) shows an OSSREMOV session with status messages.

1. Find any executing OSS processes by entering this command at the OSS shell prompt:

ps -ea

If any OSS processes are executing, stop them. (For instructions, see the Open System Services

Management and Operations Guide.)

2. Ensure that the INITIAL-DIRECTORY settings for all users have been removed. (For instructions,

see the Safeguard Reference Manual.)

If not all users’ INITIAL-DIRECTORY settings have been removed, and you tell OSSREMOV to

remove the security manager ($ZSMP), then you must do the following after you run

OSSREMOV:

a. Restart $ZSMP manually.

b. Remove all users’ INITIAL-DIRECTORY settings.

3. Remove any OSS files that contain SQL/MP code (and the corresponding SQL/MP catalog

entry).

4. If you have installed the SPI definition files on a volume other than $SYSTEM, enter this

command at the TACL prompt:

PARAM EASYSETUP^EMSVOL $vol-name

where vol-name is the name of the volume on which Event Management Service (EMS)

subvolume (ZSPIDEF) resides. This subvolume must contain the event definition files ZOSSTACL

and ZEMSTACL. The default value for this param is $SYSTEM. You are not required to have

installed SPI definition files, but if the SPI definition files are not installed in the specified

location, this utility will not generate EMS events. For more information about this param and

about enabling EMS event logging, see Table 3 (page 15).

5. If you want OSSREMOV to remove the $NULL, $ZSMP, or both $NULL and $ZSMP processes,

enter one of these commands at the TACL prompt:

• PARAM EASYSETUP^STARTUP $NULL

• PARAM EASYSETUP^STARTUP $ZSMP

• PARAM EASYSETUP^STARTUP “$ZSMP $NULL”

For more information about this param, see Table 3 (page 15).

6. Enter this command at a TACL prompt:

[RUN] OSSREMOV

7. OSSREMOV displays its start-up message, a warning message, and a prompt similar to this:

OSSREMOV - T0585H01 (01DEC2008) - December 10, 2008 17:47:05 System \NODE1

Removal of the OSS subsystem on \NODE1: STARTING

*****************************************************************

WARNING -- You are about to remove OSS from this system. This

entails removing ALL OSS data files on this system. This may

have grave consequences. Make sure no users are using the OSS

environment and all OSS applications have been terminated.

Executing this utility is similar to issuing the follow NSK or

OSS command, respectively:

TACL> FUP PURGE $*.*.*

OSS> /bin/rm -fr /

ARE YOU SURE YOU WANT TO CONTINUE WITH THIS ACTION?
