Securing your system prepares it and your users for a shutdown. Refer to "Securing the System for Tape Tasks" in Chapter 5 "Modifying Your System" for additional information about these steps.

If you are not already in the PUB group, change groups now.
```
  :CHGROUP PUB
```

Lower limits.


  :LIMIT 0,0
  :WARN@ PLEASE LOG OFF! SYSTEM UPDATE ABOUT TO BEGIN

Log users off.
Wait approximately five minutes, make sure users have saved their work and logged off, then abort jobs or sessions still executing. Use the SHOWJOB command to determine session and job numbers of work that is still in progress. Then, for each job and session still executing, type:
```
  :ABORTJOB #Jnn
  :ABORTJOB #Snnn
```
where:

Jnn

the ID number for each job to be aborted.

Snnn

the ID number for each session to be aborted.

Deactivate NS 3000/iX, if applicable.


  :NSCONTROL STOP
  :NSCONTROL ABORT
  :NETCONTROL STOP

Terminate logging processes.
1. Enter the following command to determine if user logging processes are running:
```
  :SHOWLOGSTATUS
```
  If logging processes are running on your system, a message similar to the following will be displayed:
```
  LOGID   CHANGE AUTO USERS STATE CUR REC MAX REC % USED CUR FSET
  SHPLOGID  YES   YES  1    ACTIVE  120   10016    1%     1
  ORBLOGID  YES   YES  9    ACTIVE  3812  10016   38%     1
```
  If no logging processes are running, skip to Step 6.
2. Terminate logging processes as shown below.
```
  :LOG logid,STOP
```
  where logid is the ID number for each logging process to stop.
3. Record the names of the logging processes, if you want to restart them later.
Prepare your manually installed products.
1. If you have ALLBASE/SQL, issue starts for each DBEnvironment that you want to migrate before you back up the system. Refer to the ALLBASE/SQL Database Administration Guide for more information.
2. If you have ALLBASE/4GL, unload all existing ALLBASE/4GL applications, if you have them on your system. Refer to the HP ALLBASE/4GL Developer Administration Manual for more information.
3. If you purchased and received AutoRestart/iX, install AutoRestart/iX before you run AUTOINST. Refer to the AutoRestart/iX Reference Manual for installation instructions.

For each lockworded system file, remove the lockwords.


  :LISTFILE filename,  -3
  :RENAME filename/lockword,filename

Purge spool files.
```
  :SPOOLF @;DELETE
```
Purge staging groups, if they exist.
```
  :PURGEGROUP UNL
  :PURGEGROUP USL
  :PURGEGROUP UXL
```
Verify each purge, type Y, at the prompt.
Do not purge the group install.sys or the file supacct.pub.sys, they are needed for future patch and add-on processes.
Purge specified files and groups.
1. Purge the PSIDNLD.DIAG.SYS file.
```
  :PURGE PSIDNLD.DIAG.SYS
```
  This file may have been purged already.
2. Purge each osxnn and xptnnnn group in the telesup account.
```
  :report @.telesup
  :PURGEGROUP OSxnn.TELESUP
  :PURGEGROUP XPTnnnn.TELESUP
```
  where:
  
  x
  
  an alphabetic character
  
  nn
  
  the numeric release number (for example, OSA10.TELESUP and 0SB23.TELESUP).
  
  These groups may not exist.
Rename the COMMAND.PUB.SYS file.
```
  :RENAME COMMAND.PUB.SYS,command_name
```
Where command_name is a temporary name you are assigning the file. This preserves your UDC information for later use. Record the temporary name.
