Hi, The CPAT Development team created a great F.A.Q. and I’d like to share it with CPAT users. What are the various approaches to running CPAT? Does running CPAT require altering your database?  Does CPAT write to your database? What privileges does CPAT require? Does CPAT connect to the internet? How does the checks run by CPAT compare to Oracle Estate Explorer? What versions of Java…

Hi, I’m doing some import tests to an Autonomous Database Serverless and I have a few things to share. Usually, people use the dump files in an Object Storage, but you can also use it on an FSS. The recommendation on the documentation is to use the Service High and .25 ECPU per parallel: https://docs.oracle.com/en/cloud/paas/autonomous-database/serverless/adbsb/load-data-data-pump.html#GUID-30DB1EEA-DB45-49EA-9E97-DF49A9968E24…

Hi, I’ve never been a big fan of using the System user to perform database exports and today I found another good reason not to use it. I was investigating some slowness during an export phase.

I was doing a Full export from one PDB and I got the error: Worker unexpected fatal error in KUPW$WORKER.FETCH_XML_OBJECTS [ORA-00942: table or view does…

Hi, I was helping a customer who wanted to be ready to migrate the database to 23c when it becomes available using zero or near-zero downtime upgrade techniques. Besides Oracle Golden Gate, one good technique to consider is using a logical standby database to perform a rolling upgrade of the Oracle Database. Oracle Transient Logical Standby is…

Hi, I was helping a customer who needed to migrate to Oracle Database 19c but still using JDK6 and JDK 7. Using JDK 6 and 7 to connect to Oracle Database 19c is not recommended, as Oracle Database 19c may have compatibility and security features that are best supported by later versions of the JDBC…

It highlights variations in parameters, privileges, users and roles, reserved words, patch fixes, database homes, objects, and more. ORAdiff helps answer some common questions: How frequently does the ORAdiff information get a refresh? It is…
