WEBLOGIC LOG EXTRACTOR AND SUMMARIZER

 As sysadmins, we need to daily deal with logs. It is overwhelming to check huge log files especially for application servers like weblogic which has numerous log files like diagnostic, server log, out log, OHS logs etc. It is time consuming and quickly lead to fatigue if log files are huge like weblogic. I have developed 2 scripts which extract and summarize logs. I have been using these scripts in both production and test environments. These scripts helped in quickly reacting to a situation and saved time. If your organization already has tools like Splunk, ELK, these scripts may not much use. But for those who couldn’t afford, these scripts could help. Please find brief description about each script as below:

Log Extractor: This script takes time in mins or time period as input and extracts logs produced between that time period. We can also filter log files based on log severity as shown below screenshot.
Script Location: https://github.com/RameshPoonati/oracleMiddlewareScripts/tree/master/LogExtractor

Log Summarizer: This script extracts and summarizes errors reported in log files with count against each error. It will help in getting snapshot of errors happened in past 1 hr.

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...
