- Oh cool! `select * from pg_stat_activity` shows "PostgreSQL JDBC Driver" for the application name! That's how you know it's working!
|
||||
- If you monitor the `pg_stat_activity` while you run `dspace database info` you can see that it doesn't use the JNDI and creates ~9 extra PostgreSQL connections!
|
||||
- And in the middle of all of this Linode sends an alert that CGSpace has high CPU usage from 2 to 4 PM

- The database connection pooling is definitely better!
|
||||
|
||||
|
||||
|
||||
- Now there is only one set of idle connections shared among all the web applications, instead of 10+ per application
|
||||
- There are short bursts of connections up to 10, but it generally stays around 5
|
||||
- Test and import 13 records to CGSpace for Abenet:
|
||||
|
||||
```
|
||||
$ export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xmx512m -XX:+TieredCompilation -XX:TieredStopAtLevel=1"
|
||||
$ dspace import -a -e aorth@mjanja.ch -s /home/aorth/cg_system_20Dec/SimpleArchiveFormat -m systemoffice.map &> systemoffice.log
|
||||
```
|
||||
|
||||
- The fucking database went from 47 to 72 to 121 connections while I was importing so it stalled.
|
||||
- Since I had to restart Tomcat anyways, I decided to just deploy the new JNDI connection pooling stuff on CGSpace
|
||||
- There was an initial connection storm of 50 PostgreSQL connections, but then it settled down to 7
|
||||
- After that CGSpace came up fine and I was able to import the 13 items just fine:
|
||||
|
||||
```
|
||||
$ dspace import -a -e aorth@mjanja.ch -s /home/aorth/cg_system_20Dec/SimpleArchiveFormat -m systemoffice.map &> systemoffice.log
