Restore Gotchas

Restore Libraries alphabetically

• Let's suppose you have physical files in one library called GOODSTUFF
• Let's suppose you have logical access to the GOODSTUFF files located in another library called GETGOODIES
• Let's suppose you need to restore several libraries including GOODSTUFF and GETGOODIES
• OS/400 restores libraries in ALPHABETICAL SEQUENCE
  • (unless you restoring 100% or
  • doing libraries one at a time where you specify which one each time)
• which means it will try to restore GETGOODIES before GOODSTUFF
• but if the physical file that a logical accesses is not on disk at time you try to restore the logical, you will not recover that from the backup

Other Availability Recovery Topics

Security Considerations

• Who knows passwords to Master Security?
  • such as STRSST System Security Tools
• What happens if that person gets hit by a truck, or other accident removes them from the picture?
• Let's suppose, thanks to human error, the master security signon gets messed up, and no one can sign on with it. What now?

UPS Power Protection

• Do you check Power Protection periodically, so when the battery dies of old age, that is no surprise to you ?
• When it was originally hooked up, was it tested to make sure it was hooked up correctly, so when you need it, because of loss of public utility power, it does protect you?
