Hi @Beltran,
The issues you have are related to the SAP Java Connector (sapjco). It looks like our community only has basic knowledge on the sapjco (at least I have), setting up Load Balancing with the information provided by the client is quite challenging (to say the least).
I would advice you to connect wtih SAP support, as both SAP HR/HCM and (SAP Java Connector) are supported by SAP Support
What type of support is provided to SAP customers building solutions using SAP JCo? Do SAP Customers need to purchase a support contract?
SAP customers get full support and service from SAP. This support is provided via the SAP Support Portal.
