Mystery Solved - Why My OSB Server is Taking lot of Time to Comeup

Once one of my teammates called me up and told me that OSB server in test environment is not coming up. He told me that he tried restarting servers multiple times and there is no luck.

The previous day, I have setup a monitoring script in that environment. So initially, I was misguided by a statistics related error and initial efforts gone in that direction.

From my experience, initial startup errors could be due to network or db. So I have ran lsof command and found that there was a connection to remote jms and socket status is SYN_SENT (lsof -p | grep TCP | grep -v ESTABLISHED). This gave me enough clue and revisited logs and found below error.

<11-Apr-2019 07:10:29 o’clock BST> << eis/jms/XXX_RemoteTopic > ResourceAllocationException generated by resource adapter on call to ManagedConnectionFactory.createManagedConnection(): “BINDING.JCA-12141
ERRJMS_CONN_FAC_NOT_FOUND.
ERRJMS_CONN_FAC_NOT_FOUND.
Unable to instantiate connection factory. JMS adapter was unable to look up the connection factory weblogic.jms.XAConnectionFactory neither through JNDI nor instantiate it as a Java class.

This log message has confirmed that server is waiting to connect to remote host and retrying. Instead of making changes, we have waited for 40 minutes and server came up. Post that we have removed that remote jms configuration and server startup time reduced from 40 mins to 5 mins. By default weblogic jms tries 10 times hence the delay in startup time.

Later found that this problem existed few weeks ago but the other engineer used to wait for 45 mins. But on this day, we got a new team member and she got panicked after seeing server in STARTING state for a long period and kept on restarting server. Fixing root cause saved 40 mins of our time every time we restart server.

HOW WE REDUCED SOA OSB PROVISIONING FROM 4 DAYS TO 4 HOURS

 In our organization, we’ve undertaken the task of upgrading both SOA and OSB from version 12.2.1.3 to 12.2.1.4. This involves an out-of-place migration approach, wherein we create a new environment and switch traffic during the cutover. As you know, this process typically requires several days we opt for manual provisioing. A very significant amount of automation work was previously accomplished for 12.2.1.3 by our predecessors. Despite these efforts, the process still used to take lot of time due to following factors: Bugs in existing automation. For example, SOA composite deployments is not stable which warrants lot of manual work Import of 10s of TLS Certificates into KSS Manual retiring and shutting down of services Monitoring setup Miscellaneous: Increasing Log file count, enabling GC logging, changing heap parameters, bash profile changes While our current automation initiatives have yielded substantial savings, we aimed to capitalize on this upgrade activity to enable end-t...

NOT ABLE TO START RABBITMQ CLUSTER: CANNOT DECLARE A QUEUE ‘~S’ ON NODE ‘~S’: ~255P

We have 7 node rabbitmq cluster and we are using sharding queues. We have shutdown all non prod rabbitmq nodes as part of VM patching. As it was non prod, we thought of shutting down all together instead of rolling patching. We couldn’t start the any of the rabbitmq post patching. All of nodes were failing to start with the below error: 2022-06-23 05:13:10.104845-07:00 [error] <0.647.0> “Cannot declare a queue ‘~s’ on node ‘~s’: ~255p”, 2022-06-23 05:13:10.104845-07:00 [error] <0.647.0> [“queue ‘sharding: shard.my.queue – rabbit@rabbit1’ in vhost ‘my_vhost'” This is a known issue in some old versions of rabbitmq. rabbitmq node fails to come up with above error. Work around for this is to disable sharding policy for the problematic sharding queue. It can be done either from command line or from rabbitmq admin page. It requires to connect a running node. But as all the nodes were down, we could not disable sharding policy. Luckily, rabbitmq allows disabling sharding pulgi...

SOA SUITE 12.2.1.4 INSTALLATION: GOT EXCEPTION WHEN AUTO CONFIGURING THE SCHEMA COMPONENT(S) WITH DATA OBTAINED FROM SHADOW TABLE

  We planned to do out of place upgrade from soa suite 12.2.1.3 to 12.2.1.4. As part of this, we planned to automate end to end provisioning. While executing domain configuration using ansible and python scripts, we got following error in domain creation step. Got exception when auto configuring the schema component(s) with data obtained from shadow table. Failed to build JDBC Connection object: com.oracle.cie.domain.script.jython.CommandExceptionHandler. exception. Quick internet search gave few solutions like deleting domain-registry.xml file, verifying dehydration store password supplied to script etc. But none of them helped. After trying several options, I thought I might have done some stupid error prior to domain creation step. To track down the issue, though of checking what getDatabaseDefaults actually doing. I tried to grep for the getDatabaseDefaults function call inside oracle home. But couldn’t find the source code for the python function. As a final resort, thought of...
