Mike Ellis created JCS-101:
------------------------------
Summary: Basic cache functions (store/delete) not occurring
consistently
Key: JCS-101
URL: https://issues.apache.org/jira/browse/JCS-101
Project: Commons JCS
Issue Type: Question
Components: Composite Cache
Affects Versions: jcs-1.3
Environment: Linux, running on VM
Reporter: Mike Ellis
Priority: Minor
Our process had been deployed and running since December 2010 with no problems
but two weeks ago we started seeing that updates were not working consistently,
but we were not getting errors indicating any problems. We are using version
1.3
Our setup specifies a primary and failover linux server - see cache.ccf snip
below - but we see the error even when just one server is active. Separate
domain restarts (we use VMs) did not resolve the issue. A simultaneous restart
appeared to work (existing records gone, updates happened) but the problem
reoccurred within hours.
Commands like clear and dispose also failed to work. Normal ShrinkerThread
tasks were running as expected.
Our tech support are checking that the VM environment is working correctly, but
is there a reason why store/delete/clear/dispose would not work and would not
display an error?
Also, is there a way to retrieve all existing keys from a region at runtime,
rather than setting up a group and using putInGroup(...) as records are
created? The aim is to retrieve the keys from every record in a specified
region without changing code to specify/use groups.
