Symbol migration report

If you open a backing store that was created before APAR PI66143, any stack symbols in that backing store are migrated to the new method introduced by the APAR. Previous to this APAR, each interface name defined in reusable configuration was a stack symbol for that interface's IP address, and the symbols were shared between TCP/IP and IPSec technology.

With APAR PI66143, TCP/IP symbols more resemble MVS™ system symbols. When the migration occurs, the following steps occur:
  1. The TCP/IP stack symbols are separated from the IPSec symbols. The IPSec symbols continue to work as they have previously, with an interface name being a symbol for its IP address. Interface names defined in reusable configuration are available as symbols to the IPSec technology.
  2. In the TCP/IP technology, the interface name symbols are converted to the new methodology by changing them into Network Configuration Assistant system symbols. The interface name symbol is changed to &interfacename_IPADDR. For example, an existing TCP/IP stack symbol for interface OSD1 is changed to the Network Configuration Assistant system symbol &OSD1_IPADDR.
  3. If the stack is in a sysplex, the special internally generated symbols, internalSysplex6 and internalSysplex4 are converted to &internalSysplex6. And &internalSysplex4. respectively.
The table on this panel shows all symbols that were migrated. The fields shown are:
  • Original Stack Symbol: The name of the stack symbol before migration.
  • Value: The value of the symbol, if known.
  • New System Symbol: The new name that the stack symbol was converted to, for TCP/IP technology.
  • TCP/IP filter rules affected: The names of any TCP/IP filter rules that use that symbol.
