Rhino 2.6.2 :: Rhino Administration and Deployment Guide

To find activities in the SLEE, use the following rhino-console command or related MBean operations.

Console command: `findactivities`

Command

findactivities [-maxpernode maxrows] [-node nodeid] [-removed|-all] [-ra
<ra-entity>] [-created-after date|time|offset] [-created-before
date|time|offset] [-updated-after date|time|offset] [-updated-before
date|time|offset]
  Description
    Find activities.  Use -removed to list only activities removed but not garbage
    collected.  Use -all to list all active and removed activities combined.

Options

Option

Abbreviation

Description

-maxpernode <maxrows>

Retrieve at most this many activities from each event-router node (default is 100). Can be used to limit Rhino’s load when processing the request.

-node <node-id>

Only display activities owned by the given node.

-removed

Display removed but not yet garbage collected activities instead of active activities.

-all

Display both active and removed but not yet garbage collected activities.

-ra <ra-entity>

Only display activities created by the named resource adaptor entity.

-created-after <time>

-ca

Only display activities created after the given time.

-created-before <time>

-cb

Only display activities created before the given time.

-updated-after <time>

-ua

Only display activities updated after the given time.

-updated-before <time>

-ub

Only display activities updated before the given time.

Times for the above options may be entered in either absolute or relative format:

Type Format Description Examples

Absolute

[[yyyy/]MM/dd] [HH:mm[:ss]]

yyyy = the year
MM = the month (1-12)
dd = the date of the month (1-31)
HH = the hour (0-23)
mm = the minute (0-59)
ss = the second (0-59)

2008/04/15
04/15
10:57
10:57:35
2008/04/15 10:57:35

Relative

(<nn><d|h|m|s>)*

nn = a number
d = days
h = hours
m = minutes
s = seconds

1d
1h
1m
30s
1m
7m30s
1d12h5m30s

Rhino assumes relative time format is in the past. For example, 1h30m means 1 hour and 30 minutes ago.

Finding stale activities

A common search would be for stale activities. Rhino performs a periodic activity-liveness scan, checking all active activities and ending those detected as stale. Sometimes, however, a failure in the network or inside a resource adaptor might prevent the liveness scan from detecting and ending some activities. In this case, the Administrator would have to locate and end the stale activities manually.

To narrow the search:

To search for activities belonging to node 101 (replicated or non-replicated activities owned by 101) that are more than one hour old, you would use the arguments -node 101 and -cb 1h:

$ ./rhino-console findactivities -node 101 -cb 1h
pkey                      attach-count   handle                                 namespace   node   ra-entity    ref-count   replication-mode   submission-time     update-time
------------------------  -------------  -------------------------------------  ----------  -----  -----------  ----------  -----------------  ------------------  ------------------

2 rows

(This example returned two activities.)

MBean operation: `getActivities`

MBean

Housekeeping MBean

Rhino operations

Get summary information for all activities

public TabularData getActivities(int maxPerNode, boolean includeRemoved)
    throws ManagementException;

This operation returns tabular data summarising all activities.

Get summary information for activities belonging to a resource adaptor entity

public TabularData getActivities(int maxPerNode, String entityName, boolean includeRemoved)
    throws UnrecognizedResourceAdaptorEntityException, ManagementException;

This operation returns tabular data summarising the activities owned by the given resource adaptor entity.

Get summary information for activities using time-based criteria

public TabularData getActivities(int maxPerNode, String entityName, long createdAfter, long createdBefore, long updatedAfter, long updatedBefore, boolean includeRemoved)
    throws UnrecognizedResourceAdaptorEntityException, ManagementException;

This operation returns tabular data summarising the activities owned by the given resource adaptor entity using the time-based criteria specified (in milliseconds, as used by java.util.Date, or the value 0 to ignore a particular parameter).

Get summary information only for removed but not yet garbage collected activities using time-based criteria

public TabularData getRemovedActivities(int maxPerNode, String entityName, long createdAfter, long createdBefore, long updatedAfter, long updatedBefore)
    throws ManagementException, UnrecognizedResourceAdaptorEntityException;

This operation returns tabular data summarising the removed activities owned by the given resource adaptor entity using the time-based criteria specified (in milliseconds, as used by java.util.Date, or the value 0 to ignore a particular parameter).

Results depend on the Housekeeping MBean that invokes the operation:

Cluster Housekeeping MBean — returns results from all event-router nodes in the primary component
Node Housekeeping MBean — returns results from that node only.

For a description of the format of the tabular data that these operations return, see the javadoc.
