Question

I have a problem with my Liferay Cache.

Scenario :
I am reading an XML file and importing layouts to my Liferay DB using Liferay API.

There is huge data being stored in the typeSettings column of the layout.

Problem :
When I am importing around 5000 layouts, I get an OutofMemoryException.
I could find the most retained Heap Space is by the EhCache object.
(which holds the LayoutCacheModel with my huge typesettings)

Is it a good idea to clear the cache after each layout import ?

If so, how can I clear the cache specific to layouts. (I am using Liferay 6.0)

Thanks,

Siby

Similar to the answer given by @ramsinb I was able to clear the cache using code from :

LayoutPersistenceImpl.java

public void clearCache() {
    if (_HIBERNATE_CACHE_USE_SECOND_LEVEL_CACHE) {
        CacheRegistryUtil.clear(LayoutImpl.class.getName());
    }

    EntityCacheUtil.clearCache(LayoutImpl.class.getName());
    FinderCacheUtil.clearCache(FINDER_CLASS_NAME_ENTITY);
    FinderCacheUtil.clearCache(FINDER_CLASS_NAME_LIST);
}

I had to manually copy this code as its not available as a service.
