How to get Java8 Metaspace dump (not heap dump)

由 情到浓时终转凉″ 提交于 2019-11-30 08:40:17
Are there any tools that are able to get Metaspace dump from a Java8 hotspot vm ? It seems you encounter a class loading leak. Use jmap -clstats PID to dump class loader statistics; jcmd PID GC.class_stats to print the detailed information about memory usage of each loaded class. The latter requires -XX:+UnlockDiagnosticVMOptions . The heap dump will also help, because each class in the Metaspace has a corresponding java.lang.Class instance in the heap. 来源： https://stackoverflow.com/questions/37919215/how-to-get-java8-metaspace-dump-not-heap-dump

Thanks! 回答1: i never done something like this before ;) this will compile some c source, create a b.bash script

问题 im using DBI in Perl to connect to my PostgreSQL Database. Everything is working fine but in my debugging (printing results etc.) iam not able to see if the query prepared by perls DBI module is really correct.

问题 How can I get a SQL dump of a SQL Server 2008 database? That is, a .sql file with inserts to regenerate the data in another database, much like mysqldump. 回答1: From SQL Server Management Studio you can use the Generate Scripts command in the Tasks item of the right-click menu on the target database. From here you generate scripts for the structure and data and SPs etc: make sure 'Script Data' is set to True in the scripting options to get the inserts. 回答2: Not finding what I needed

问题 I'm looking for a function to dump variables and objects, with human readable explanations of their data types. For instance, in php var_dump does this. $foo = array(); $foo[] = 1; $foo['moo'] = 2; var_dump($foo); Yields: array(2) { [0]=> int(1) ["moo"]=> int(2) } 回答1: A few examples: foo <- data.frame(1:12,12:1) foo ## What's inside? dput(foo) ## Details on the structure, names, and class str(foo) ## Gives you a quick look at the variable structure Output on screen: foo <- data.frame(1:12,12
