Ask a question about rocketmq-CodePudding

Excuse me under Linux configuration rocketmq are there any requirements on memory size, I buy 1 g memory server has to run the MySQL tomcat, free m see only 200 m memory me the runserver then executes sh file and runbroker sh all set within 200 m, the size of the boot server and broker to check the log said start is successful, but I run the test class is an error, seemed to me the memory problems

is my remaining memory is too small, please

CodePudding user response:

There is insufficient memory for the Java Runtime Environment to continue.

Means that the rest of the memory for the JRE

CodePudding user response:

reference 1st floor LCL_data response:

this memory reserve how much is it gonna be? Probably, eating so much memory

CodePudding user response:

1 gb of memory is too little, the server at least 16 g, most of the 32 gb

CodePudding user response:

reference LCL_data reply: 3/f

1 gb of memory is too little, the server at least 16 g, most is 32 g

I just buy a server to do the test to learn mq behind me to modify the view in sh after size is normal, but I copy of the official synchronous producers in the process of testing the demo, normal production, consumption, but with asynchronous demo complains why not:

Because synchronous producers default TopicTest is the name of the topic in the Message, I start a topic name has the same error MQClientException: No route info of this topic, opicTest, a little don't understand

CodePudding user response:

Lz you later to set how much memory, I also am 1 gb of memory, encounter the same problem with you

CodePudding user response:

Before you start modify rocketmq can occupy memory size

CodePudding user response:

It is better to your computer the virtual machine

CodePudding user response:

You are not only changed the runserver then executes. Sh start memory value, but also change runborker. Sh, specific modification can reference
Step 1: modify the runserver then executes. Sh the JVM parameters:

The original parameter value:

JAVA_OPT="${JAVA_OPT} - server - Xms4g - Xmx4g - Xmn2g - XX: XX: MetaspaceSize=128 m - MaxMetaspaceSize=320 m"
The modified parameter value:

JAVA_OPT="${JAVA_OPT} - server - Xms128m - Xmx128m - Xmn128m - XX: XX: MetaspaceSize=128 m - MaxMetaspaceSize=128 m"
Note: according to the server configuration to set

Step 2: the JVM parameters of the modified runborker. Sh

The original parameter value:

JAVA_OPT="${JAVA_OPT} - server - Xms8g - Xmx8g - Xmn4g"
The modified parameter value:

JAVA_OPT="${JAVA_OPT} - server - Xms128m - Xmx128m - Xmn128m"
