Summary :
To optimize liveCache performance and prevent errors, appropriate settings for the operating system parameters are crucial, especially after modifications such as changes to DATA_CACHE or CACHE_SIZE, updates according to Note 425051, expansions in Devspaces data, and adjustments in MAXUSERTASKS and/or MAXCPU. Incorrect configurations may lead to liveCache failing to start. Operating system limitations that restrict memory allocation or fail to support the required number of user kernel threads also contribute to these issues. SAP recommends checking the necessary parameters like MAXCPU, OMS_HEAP_LIMIT, etc., in detailed notes and ensuring that the liveCache and operating system configurations are aligned, with sufficient SWAP space and supported package levels.
