Change region cache use SPEL V2105

[djboyd4715]

We are working on an upgrade from CCV1 V6.4 to CCV2 V2105.

Understanding is that when deploying to the SAP Public cloud, it is strongly recommended to make use of dynamic allocation instead of fix.

At this time we have defined 4 custom cache regions as well as have set the size for the standard OOTB regions. Here is what we have for our 6.4.

• regioncache.productregion.size=2500
• regioncache.pricerowregion.size=32000
• regioncache.unitcacheregion.size=5000
• regioncache.userscacheregion.size=25000

OOTB

• regioncache.querycacheregion.size=150000
• regioncache.entryregion.size=150000
• regioncache.typesystemregion.size=50000

Do I do something like the following where heap size is 4 GB

{ "key":"regioncache.productregion.size", "value":"#{ 2500000 * ( T(java.lang.Runtime).runtime.maxMemory() / ( 1024 * 1024 * 1024 * 4.0 ) ) }"

},

{ "key":"regioncache.pricerowregion.size", "value":"#{ 32000000 * ( T(java.lang.Runtime).runtime.maxMemory() / ( 1024 * 1024 * 1024 * 4.0 ) ) }"

},

Hi David,

So you customized the region cache on CCv1 by adding 4 custom regions and configured the OOTB regions as well, on CCv2 you will need to move the customization and configuration as well.

And you can even reuse your existing local configuration files like local.properties file on CCv2, by mentioning the local files in manifest.json file.

what should be the max limit for regioncache.entryregion.size? By default it is 100K.

Did you mean entityregion and not entryregion? We don't have entry region. The max limit could depend on the total heap memory allocated to the JVM process. In a small or medium size sandbox environment, it could be 500k ~ 800k. Also the total cache size for all regions depends on your Commerce Cloud license.
