Examples of Segment Spaces

The products you choose to combine in a segment space and the location you load them at will vary depending on your users' requirements. The page ranges shown may not be the actual page ranges of these programs.

To see a sample storage mapping for a given set of applications, see Setting Up Your Storage Layout. The following are examples of what CP might return in response to QUERY NSS commands for varying configurations of applications:

1. GDDMXAL contains GDDM/GKS, GDDM/IMD, and GDDM/IVU:

   query nss map name gddmxal
   FILE FILENAME FILETYPE MINSIZE BEGPAG ENDPAG TYPE CL #USERS PARMREGS VMGROUP
   1112 GDDMXAL  DCSS-S     N/A   00600  006FA   --  A  00000   N/A      N/A
   1113 ADMGK000 DCSS-M     N/A   00600  00658   SR  A  00000   N/A      N/A
   1114 ADMIM000 DCSS-M     N/A   00660  006C4   SR  A  00000   N/A      N/A
   1115 ADMIV110 DCSS-M     N/A   006D0  006FA   SR  A  00000   N/A      N/A
   Ready; T=0.01/0.01 12:57:46

2. SQLDCS1 contains some of the SQL segments and QMF:

   query nss map name sqldcs1
   FILE FILENAME FILETYPE MINSIZE BEGPAG ENDPAG TYPE CL #USERS PARMREGS VMGROUP
   1069 SQLDCS1  DCSS-S     N/A   00700  008C0   --  A  00000   N/A      N/A
   1070 QMF220E  DCSS-M     N/A   00700  0084F   SR  A  00000   N/A      N/A
   1071 SQLRMGR  DCSS-M     N/A   00850  00860   SR  A  00000   N/A      N/A
   1072 SQLISQL  DCSS-M     N/A   00861  008C0   SR  A  00000   N/A      N/A
   Ready; T=0.01/0.01 12:58:42

3. SQLDCS2 contains SQL segments that are not used by QMF:

   query nss map name sqldcs2
   FILE FILENAME FILETYPE MINSIZE BEGPAG ENDPAG TYPE CL #USERS PARMREGS VMGROUP
   1073 SQLDCS2  DCSS-S     N/A   00900  00AA6   --  A  00000   N/A      N/A
   1074 SQLSQLDS DCSS-M     N/A   00900  009D0   SR  A  00000   N/A      N/A
   1075 SQLXDRS  DCSS-M     N/A   009D1  00AA6   SR  A  00000   N/A      N/A
   Ready; T=0.01/0.01 12:58:53

   You should consider defining both SQLDCS1 and SQLDCS2 as shown because QMF may use SQLRMGR and SQLISQL, but will not use the SQL segments in SQLDCS2.

4. GAMDCSS contains GAM/SP (Graphics Access Method/SP) segments and GDDM/graPHIGS. In this case, the segment space is still class S because the GDDM/graPHIGS segment, AFMASS00, has not yet been saved. Although the GAM segments have been saved, they cannot be used until member AFMASS00 has been saved.

   query nss map name gamdcss
   FILE FILENAME FILETYPE MINSIZE BEGPAG ENDPAG TYPE CL #USERS PARMREGS VMGROUP
   1146 GAMDCSS  DCSS-S     N/A   00800  008F3   --  S  00000   N/A      N/A
   1147 CMSGAM   DCSS-M     N/A   00800  0080F   SR  A  00000   N/A      N/A
   1148 GAMBUF   DCSS-M     N/A   00810  00811   SW  A  00000   N/A      N/A
   1149 AFMASS00 DCSS-M     N/A   00812  008F3   SR  S  00000   N/A      N/A
   Ready; T=0.01/0.02 16:29:09
