Hi Mark,

On the slowness, this is when they are retrieving random .js files from the 
exploded war file after deployment.

To clarify, these are .js files loaded directly from the file system? They are not packaged in a JAR file?

It's taking an a long
  amount of time. Some of these are quite large, like 2MB or more. When the 
issue shows, doing a curl we get to here and then it pauses for some time 
before it feeds back the data.

And it just hangs out here before finally getting the requested file.

How repeatable is this?

How long does it hang before delivering content? Is it always the same or does it vary.

Which connector are you using?

What Tomcat version did you upgrade from?

How does the problem before the upgrade compare to the problem after the upgrade?

What component is serving the content? Is it Tomcat's default servlet or is it something else?

When it happens, take 3 thread dumps a few seconds apart. The aim is to figure out why it is hanging.

In looking at the catalina.out log file, I am not seeing any 
errors/stack-traces.

Any ideas as to what may be causing this?

Not at the moment. The information requested above should at least narrow down which parts we need to think about.

Mark

Hello gentle beings,

I have a couple of application teams having issues since getting upgraded to
Tomcat 9.0.71.

Upgrading from which Tomcat version?

The main one has to do with an application that has run fine in the past is
now exceeding max cursors with their Oracle Database datasource. They are
using spring framework to control the Database operations. Here is what
their resource looks like:

<Resource name="jdbc/f***" auth="Container"
type="javax.sql.DataSource"
                 maxTotal="100" maxIdle="30" maxWaitMillis="15000"
                 username="${datasource.fm.username}"
password="${datasource.fm.password}"
driverClassName="oracle.jdbc.OracleDriver"

url="jdbc:oracle:thin:@(Description=(CONNECT_TIMEOUT=10)(RETRY_COUN
T=3)(ADDRESS_LIST=(LOAD_BALANCE=on)(FAILOVER=ON)(ADDRESS=(PROT
OCOL=tcp)(HOST=***************)(PORT=3203))(ADDRESS=(PROTOCOL=
tcp)(HOST=*****************)(PORT=3203)))(CONNECT_DATA=(SERVICE
_NAME=ceofm_u)))"/>

Here is an error from the log file:

[‎3/‎2/‎2023 1:50 PM]  Burgos, Maria D.:
here is the error in catalina.out

ate.java:1542)

org.springframework.jdbc.core.JdbcTemplate.execute(JdbcTemplate.java:66
7)

Any chance we can see a root cause for that? Something from the JDBC
driver?

The other team is having performance issues when using static .jar
resources in their war file. One part of the app, on the browser side
measurements, is taking 2.2 minutes to load. This started getting worse after
moving to 9.0.71. Are there any known issues that could be causing this?
Currently waiting for 9.0.73 to get release. :)

Do you mean static resources stored in a JAR's META-INF/resources
directory?

Is the WAR deployed in packed or unpacked form?
