Computing paradigms today tend to new standards and Kubernetes […]

Q: Where does the 5000ms timeout come from when I get “process(Lweblogic.cluster.messaging.internal.ClusterMessage;) timed out after: 5000ms..”?

And we said: The 5000ms is the currently default value for DatabaseLessLeasingBasisMBean.MessageDeliveryTimeout mbean propety. This is the stack trace generated by a weblogic managed server leader in a cluster defined with consensus migration in wich another cluster node probably died (or was very busy): Apr 25, 2016 10:47:42 AM CEST> <Warning> <RJVM> <BEA-000573> <RequestTimeout for […]

ApacheDS, user groups membership and WebLogic

In ApacheDS, the ldap search for getting the group names a user (for instance cn=juan,ou=usuarios,0=acmecorp) belongs to is as follows: (& (objectClass=groupofuniquenames) (uniqueMember=2.5.4.3=juan,2.5.4.11=usuarios,2.5.4.10=acmecorp) ) In weblogic, for the supported ldap auth providers, the user membership configuration pattern setting is: (&(<someattribute>=%M)(objectclass=<someobjectclass>)) Therefore a custom authenticator provider is needed in order to get it working. Enjoy 😉 […]

WLS WorkManager

This WLS WorkManager has been configured in a 6-node WLS cluster serving the first travel & tourism technology provider company website in the world. In weblogic.xml: <wl-dispatch-policy> RSSworker </wl-dispatch-policy> The following can be done in weblogic.xml or you can configure it with WLS console at runtime (better because is decoupled): <work-manager> <name>RSSworker</name> <capacity> <name>DELmaxcap</name> <count>10</count> […]
