CDC Replication source system:
- 100 GB—Default value for the
Staging Store Disk Quota for each instance of CDC Replication. Use the IBM® Data Replication configuration tool to configure disk space for
this quota.
- 5 GB—For installation files, data queues, and log files.
- Global disk quota—Disk
space is required on your source system for this quota which is used to store in-scope change data
that has not been committed in your database. The amount of disk space required is determined by
your replication environment and the workload of your source database. To improve performance,
CDC Replication will only persist LOB data to disk
if RAM is not available. Use the mirror_global_disk_quota_gb system parameter
to configure the amount of disk space used by this quota.
CDC Replication target
system:
- 5 GB—For installation files, data queues, and log files.
- Global
disk quota—Disk space is required on your target system for this quota which is used to
store LOB data received from your CDC Replication
source system. The amount of disk space required is determined by your replication environment and
the amount of LOB data you are replicating. The minimum value is 1 GB. To improve performance,
CDC Replication will only persist LOB data to disk
if RAM is not available on your target system. Use the
mirror_global_disk_quota_gb system parameter to configure the amount of disk
space used by this quota.
