Add a data-path to an existing CDCStore agent configuration (.cab) file.
Syntax
sqdconf add <cab_file_name>
--number-of-blocks=<blocks_per_file>
--number-of-logfiles=<number_of_files>
--data-path=<directory_name>
Keyword and Parameter Descriptions
<cab_file_name> - Must be specified and must match the name specified in the previous create command.
[--number-of-blocks=<blocks_per_file> | -b <blocks_per_file>] - The number of 8MB blocks allocated for each file defined in the new data-path for transient CDC storage. The default value is 32.
[--number-of-logfiles=<number_of_files> | -n <number_of_files>] - The number of files that can be allocated in the new data-path. Files are allocated as needed one full file at a time, during storage agent operation. CDCStore recycles blocks when possible before new storage is allocated. The default value is 8.
--data-path=<directory_name> - The new path and directory name, where the storage agent will create transient storage files. The directory must exist and the user-id associated with the agent must have the right to create and delete files in that directory.
Notes:
1.Unlike the Capture/Publisher configuration files, changes to the CDCStore configuration file take effect immediately and do not require the usual stop/apply/start sequence.
2.Storage Pool Directories added using --data-path=<directory_name) will be used only after all previously allocate files have been created and filled.
3.Files or Directories once allocated and used will not be freed or released by the Storage Agent while it is running.
