Overview

I learn to migrate an Amazon RDS for Oracle Database to Amazon Redshift referring this tutorial https://docs.aws.amazon.com/dms/latest/sbs/CHAP_RDSOracle2Redshift.html

Trouble

In step5, I use Amazon SCT to convert the Oracle Schema to Amazon Redshift. But, I have to change config for Amazon SCT because the tutorial document is old written in 2017. One of the change config, I try to disable to use AWS Glue. I open Project settings to uncheck the checkbox "Use AWS Glue". And soon after, AWS SCT froze.

My PC has 8GB memory, and I try business PC which has 16GB memory. Still it is useless.

What I try

According to this blog,I need to increase JVM size. So, I edit the configuration files for SCT.

[Application]
app.name=AWS Schema Conversion Tool
app.version=1.0.645
app.runtime=$ROOTDIR\runtime
app.identifier=com.amazon.sct
app.classpath=$ROOTDIR\app\AWSSchemaConversionTool.jar;$ROOTDIR\app\AWSSchemaConversionToolBatch.jar
app.mainjar=$ROOTDIR\app\AWSSchemaConversionTool.jar
app.mainclass=com.amazon.sct.App

[JavaOptions]
-Xss128M
-Dfile.encoding=UTF-8
-XX:+UseParallelGC
--add-opens=java.base/jdk.internal.loader=ALL-UNNAMED
--add-exports=java.base/jdk.internal.loader=ALL-UNNAMED
--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED

[JVMUserOptions] #add
–Xmx4096m        #add 
–Xms2048m        #add

[ArgOptions]

I finish editing the files and restart AWS SCT, but JVM memory does not increase.

I have no idea about sovling the trouble. What should I do next? Please help me.

Resolution

Once, I uninstalled AWS SCT, and I reinstalled old version one. Then, I could open the Project settings windows and uncheck [Use AWS Glue] Project settings
