Move a HiRDB/Parallel Server front-end server (FES1) and back-end server (BES1). The procedure is detailed below.
To move the servers, you must re-estimate the memory requirements for unit 2. You may also need to modify operating system parameters of the OS. For details about memory requirements and evaluating operating system parameters, see the manual HiRDB Version 8 Installation and Design Guide.
For details about unloading table data on a per-RDAREA basis, see the manual HiRDB Version 8 Command Reference.
pdstop |
Check that HiRDB terminates normally.
pdlogls -d sys -s bes1 |
pdlogunld -d sys -s bes1 -g log01 -o /unld/unldlog01 |
If you decide not to unload the system logs, use the pdcopy command to back up all RDAREAs. For details about making backups, see 6.4 Examples of backup.
pdlogrm -d sys -s fes1 -f /sysarea/log01 1 |
Create HiRDB system definitions that reflect the change in the server configuration.
pdloginit -d sys -s fes1 -f /sysarea/log01 -n 5000 1 |
Because you re-created the status files, the error shutdown status of the RDAREAs is not inherited. If necessary, use the pdhold command to place RDAREAs in shutdown status again.
pdconfchk |
If errors are detected, correct the HiRDB system definitions, and then execute the pdconfchk command again.
pdstart |
For details about making backups, see 6.4 Examples of backup.
For details about re-initializing RDAREAs, see 15.4 Increasing the size of an RDAREA or modifying its attributes (RDAREA reinitialization).
Use the unload data file that you created in step (2) as input data. For details about reloading on a per-RDAREA basis, see the manual HiRDB Version 8 Command Reference.
For details about making backups, see 6.4 Examples of backup.
Check if the following operands in the client environment definitions are specified; if the front-end server (FES1) that you moved is specified in these operands, change their values as appropriate:
It is recommended that after the command has executed you check whether or not the execution results are correct. For details on how to check command execution results, see the manual HiRDB Version 8 Command Reference.
