The available options are:
Expand
Option Description
-t, --time n
Deletes pending operations older than n hours. (Default: 1)
-u, --uuid uuid Prunes only applications with the given UUID.

Note

In most scenarios, you should not need to use the oo-admin-clear-pending-ops command directly. It is most commonly run automatically by the ose-upgrade tool as part of the upgrade process described in the OpenShift Enterprise Deployment Guide. This ensures the database is in a consistent state before data migrations happen.

9.1.5. oo-admin-console-cache

Modifying the HAProxy Multiplier

The HAProxy multiplier sets the ratio of how many HAproxy cartridges are enabled for application scaling. Setting the multiplier number to 2 means that for every two gears, one will have HAProxy enabled. Alternatively, you can set the minimum and maximum number of HAProxy cartridges allowed in scaling.

Modify the number of HAProxy multplier using the oo-admin-ctl-app command with the --multiplier option. 
# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2# oo-admin-ctl-app -l username -a appname --cartridge haproxy-1.4 -c set-multiplier --multiplier 2

Many common administrative tasks make use of the oo-admin-ctl-user command:

9.1.16. oo-admin-move
Copia collegamento

This command moves a gear from one node to another. Note that moving gears requires the rsync_id_rsa private key in the broker host's /etc/openshift/ directory and the public key in each node host's /root/.ssh/authorized_keys file as explained in the OpenShift Enterprise Deployment Guide at https://access.redhat.com/site/documentation. A gear retains its UNIX UID when moved, therefore cross-district moves are only allowed when the destination district has the same gear UID available.
To move a gear from one node to another, use the oo-admin-move command on the broker host, specifying the desired gear's UUID and the node host you wish to move the gear to:

Example 9.4. Moving a Gear From One Node to Another

# oo-admin-move --gear_uuid 3baf79139b0b449d90303464dfa8dd6f -i node2.example.com

9.1.17. oo-admin-repair
Copia collegamento

This command checks for and fixes various inconsistencies in the MongoDB datastore on the broker. For example, because a mismatch in SSH keys can be a potential security risk, the tool fixes any mismatches found by taking information from the broker datastore and pushing it to the gear. See the --help output for additional uses. 
# oo-admin-repair
Copy to Clipboard Toggle word wrap

9.1.18. oo-admin-upgrade
Copia collegamento

This command upgrades custom and community cartridges on a gear to the latest available version and applies gear-level changes that affect cartridges. See Section 5.3, “Upgrading Custom and Community Cartridges” for more information on the upgrade process and oo-admin-upgrade command usage.

Important

The oo-admin-upgrade tool is also often required when applying asynchronous errata updates provided by Red Hat for OpenShift Enterprise. See the latest OpenShift Enterprise Deployment Guide at https://access.redhat.com/site/documentation for usage instructions as it applies to these types of updates.

9.1.19. oo-admin-usage
Copia collegamento

The oo-admin-usage command displays a resource usage report for a particular user, or aggregated usage data of all users. The output includes usage type, gear ID, and duration. 
 oo-admin-usage [-l username] [options]oo-admin-usage [-l username] [options]oo-admin-usage [-l username] [options]oo-admin-usage [-l username] [options]oo-admin-usage [-l username] [options]

If -l username is omitted, the command displays aggregated data on all users.
Other options further restrict the output:

Option Description
-a, --app application_name
Filters usage data by the given application name.
-g, --gear gear_id Filters usage data by the given gear ID.
-s, --start start_date Filters usage data by the given start date, expressed as ISO dates (YYYY-MM-DD).
-e, --end end_date Filters usage data by the given end date, expressed as ISO dates (YYYY-MM-DD).
The following table provides more information on the output of this command:
Expand
Field Description
Usage Type
GEAR_USAGE is related to how long a gear has been in use with the gear size in parentheses.
ADDTL_FS_GB is related to how long additional storage has been in use on a gear with the number of GBs in parentheses.
Gear ID Gear ID indicates the UUID of the relevant gear with the associated application name in parentheses.
Duration Duration indicates the start and end time of the gear (or start time and PRESENT if still in use).

9.1.20. oo-admin-ctl-cartridge
Copia collegamento

In OpenShift Enterprise 2.1, the oo-admin-ctl-cartridge command facilitates cartridge management on the broker, including importing cartridge manifests from nodes and activating or deactivating cartridges. This command must be used to ensure that newly installed or updated cartridges can be used in applications.

Note

This command is not used for cartridge management in OpenShift Enterprise 2.0.

See Also:

9.1.21. oo-register-dns
Copia collegamento

This command updates DNS A records in BIND by wrapping an nsupdate command. Normally this command is used for broker or node hosts, although it can be used for other infrastructure hosts. Do not use this command to change DNS records for applications and gears, because these are CNAME records.
