RDAREA creation

Define RDAREAs in HiRDB file system areas for RDAREAs. Figures 25-40 and 25-41 show definition examples of creating user RDAREAs and system RDAREAs in different HiRDB file system areas on shared disks. Each system configuration is described following the figure. When you use the standby-less system switchover (effects distributed) facility, you define RDAREAs in HiRDB file system areas created on a different shared disk for each server.

Example of create rdarea statement specification

 
create rdarea SMAST for masterdirectory                   1
  file name "/sds0111/srd01" initial 10 segments;
create rdarea SDIR for datadirectory                      2
  file name "/sds0112/srd02" initial 5 segments;
create rdarea SDIC for datadictionary                     3
  file name "/sds0113/srd03" initial 20 segments;
create rdarea SUSR01 for user used by PUBLIC              4
  file name "/sds0121/srd04" initial 500 segments;
create rdarea SUSR02 for user used by PUBLIC              5
  file name "/sds0131/srd05" initial 500 segments;

Explanation

Creates the SMAST master directory RDAREA in the HiRDB file system area on shared disk A.
Creates the SDIR data directory RDAREA in the HiRDB file system area on shared disk A.
Creates the SDIC data dictionary RDAREA in the HiRDB file system area on shared disk A.
Creates the SUSR01 user RDAREA in the HiRDB file system area on shared disk B.
Creates the SUSR02 user RDAREA in the HiRDB file system area on shared disk C.

Example of create rdarea statement specification

 
create rdarea PMAST for masterdirectory                      1
    server name DIC file name "/dic0111/prd01"
    initial 10 segments;
create rdarea PDIR for datadirectory                         2
    server name DIC file name "/dic0112/prd02"
    initial 5 segments;
create rdarea PDIC for datadictionary                        3
    server name DIC file name "/dic0113/prd03"
    initial 20 segments;
create rdarea PUSR01 for user used by PUBLIC                 4
    server name BACK01 file name "/back0121/prd04"
    initial 500 segments;
create rdarea PUSR02 for user used by PUBLIC                 5
    server name BACK02 file name "/back0231/prd05"
    initial 500 segments;

Explanation

Creates the PMAST master directory RDAREA in the HiRDB file system area on shared disk A.
Creates the PDIR data directory RDAREA in the HiRDB file system area on shared disk A.
Creates the PDIC data dictionary RDAREA in the HiRDB file system area on shared disk A.
Creates the PUSR01 user RDAREA in the HiRDB file system area on shared disk B.
Creates the PUSR02 user RDAREA in the HiRDB file system area on shared disk C.
