Performance issue when calling procedure from other packages

in SQL Performance (MOSC) 3 commentsAnswered

Hi,

We're experiencing a strange performance issue with one of our APIs on a specific database. The version is 18.0.0.0.0 SE2 on Linux x64 Redhat.

This APIs works fine on our DBs and on our clients' DBs, on different versions, 11g, 12c and 19c.

After enabling our custom tracing mecanism, we could determine that the issue comes when some procedures referenced in other packages are called. So what I mean is just the call of the procedures from other packages can take several seconds. No code involved, no SQL statements, just the call. We could see that because we trace the beginning and the end of our procedures' code.

Howdy, Stranger!
