This topic describes how to set quotas for database objects.

  1. Log into the Delphix Management application.
  2. Select Manage > Datasets.
  3. Select the Configuration tab for the object you want to set a quota for.
  4. Select the Policies tab and from the Quota tile select Customize this policy.
  5. In the Quotas column, click next to the group or object for which you want to set a quota.
  6. In the Quota Policy window enter the amount of storage space you want to allocate for a quota.
  7. Click Save to set the amount.

Quotas and Low Space Errors

Be very careful setting quotas. As a group or virtual database (VDB) approaches the quota level, snapshots may fail and logs may not be captured, causing LogSync to fail.

Quota Thresholds

The following is a table of the thresholds and a description of the actions taken at each threshold. This behavior is generic across all engines.

Thresholds

Default Ranges

Actions Taken

CriticalQuota ≥ 95%
  • Disable VDBs and dSources under quota (for a group quota, everything inside gets disabled).
  • Disallow jobs detailed in the DB actions table below.
  • Cancel all in-flight jobs listed in the DB actions table except for enable.
  • Poll every minute.
Resume95% > Quota ≥ 90%
  • VDBs and dSources disabled by critical quotas will not be automatically re-enabled (DBs can still be manually re-enabled).
  • Resume fault is triggered if the quota has fallen from the critical threshold and if a DB was disabled from hitting the critical threshold.
  • Warning fault is triggered.
  • Poll every 3 minutes.
Warning90% > Quota ≥ 80%
  • Warning fault is triggered.
  • VDBs and dSources disabled from hitting critical quota will be re-enabled.
  • Poll every 3 minutes.
Safe80% > Quota
  • VDBs and dSources disabled from hitting critical quota will be re-enabled.
  • Poll every 5 minutes.

If a DB was disabled prior to reaching the critical quota, it will not be automatically re-enabled when falling to an acceptable range or when the quota is removed.

Disallowed Database Actions when in Quota Critical Threshold

Here is a table of the actions that are not allowed when the quota is in the critical threshold.

DB Actions Table

Target is Group

Target is not Group

  • Refresh target in group.

  • Sync target in group.

  • Link into group.

  • Provision into group.

  • Enable target in group.
  • Refresh target in group.

  • Sync target in group.

  • Enable target in group.

If a critical quota is placed on a target, dSources, and VDBs can still provision to groups that are quota below the critical threshold.
