Dear Splunk,

2012-03-21 15:54:51,020 0 [main] ERROR com.splunk.jdbcscriptedinput.Main - java.lang.OutOfMemoryError: Java heap space
2012-03-21 16:34:32,108 0 [main] INFO com.splunk.jdbcscriptedinput.QueryRunner - Retrieved and printed 1226776 rows.
2012-03-21 16:35:32,111 60003 [main] INFO com.splunk.jdbcscriptedinput.QueryRunner - Time expired. Ending query loop.

Do you know how to increase the limit of this Java heap space ?

Thanks

As per Brian's suggestion :

If it is this app you are referring to :

  • open splunkjdbcscriptedinput\bin\run.sh
  • after the "java" command paste in the JVM heap settings

    java -Xmx256m -Xms512m -cp .:lib/* com.splunk.jdbcscriptedinput.Main $QUERY_NAME/query.properties $QUERY_NAME/query.pointer 2> $LOG_PATH

You can use larger heap memory sizes depending on your JVM architecture(32/64 bit)

Uh, need more information.

What app is this? Usually for java you can look for the "java -Xmx256m -Xms512m" line which sets the max (mx) and min (ms) memory used.

I'm not familiar with this script, so I couldn't really tell you where to modify it.

Is this a Splunk provided script? Or part of an app?
