Hi All,
Today I am seeing this error in many places in swalog, bi_server1.log,How to resolve "GC Overhead limit exceeded" error in OBIEE 11g?
Thanks,

Hi
This normally happens to us when there is more data to fetch or does not fit or poor performance of database.
Raise it with Oracle and see what they say on this.
Exception in thread thread_name: java.lang.OutOfMemoryError: GC Overhead limit exceededCause: The detail message "GC overhead limit exceeded" indicates that the garbage collector is running all the time and Java program is making very slow progress. After a garbage collection, if the Java process is spending more than approximately 98% of its time doing garbage collection and if it is recovering less than 2% of the heap and has been doing so far the last 5 (compile time constant) consecutive garbage collections, then a java.lang.OutOfMemoryError is thrown. This exception is typically thrown because the amount of live data barely fits into the Java heap having little free space for new allocations.Action: Increase the heap size. The java.lang.OutOfMemoryError exception for GC Overhead limit exceeded can be turned off with the command line flag -XX:-UseGCOverheadLimit.
java.lang.OutOfMemoryError
-XX:-UseGCOverheadLimit
Hope this helps

So you have something to investigate now.
PS: do not randomly change any heap size just because it's the suggested action, first find out why suddenly you have an error you never had before.

I scheduled the report in OTBI and the agent was run successfully. However, I do not receive the report after the run in my inbox. The addresses are properly recorded, and the report is in an excel format and saved as a pivot table in otbi. What can be the cause?
Anyone has any idea why the OAC documentation on custom viz is not available now? I was able to access till last week - https://docs.oracle.com/en/cloud/paas/analytics-cloud/acsdv/build-package-extension.html. Does this mean OAC doesnt support custom viz or custom workbook extensions?
