Hello,
We are running 13 different SAP production systems on our Production hardware cluster machines : node A and node B.
Platform info:
Model: "ia64 hp Superdome2 16s"
Release: HP-UX B.11.31
All our SAP databases are running on Oracle 11.2.0.2.0 (non MCOD, we have 13 distinct Oracle home)
All our SAP systems are running on Neweaver 7.00 or higher ; PI 7.31, EP7.31 ECC6 EHP.5, BW 7.3 , etc ...
NodeA and nodeB are the two nodes of the hardware cluster ; 7 sap systems run by default on NodeA and 5 sap system run by default on nodeB, in case of a hardware failure the systems switch to the other cluster node.
When the sap systems are running in their default cluster node, they use a 11.2.0 Instance client (11.2.0.2 or 11.2.0.3) but when the sap systems switch over to the other cluster node, an outdated Oracle 10.2.0.5 Oracle Client has been configured :

.dbenv.2.sh: ADD=/oracle/client/10x_64/instantclient
I think this is not supported , as mentioned in sap note 819829
"Use Oracle Instant Clients of release 10.2 only if your database is running on Oracle Database Release 10.2."
This has been done by a dishonest external consultant one year ago, without us noticing it.
We are now in the process of cleaning this mess, so we are reviewing in detail "SAP note 819829 - Oracle Instant Client Installation and Configuration on Unix"
As you can understated we could have potentially 13 sap systems of different shape and colors (ABAP,Java,dual stack, 7.00, 7.31) running on the same Hp-UX Superdome node , we were wondering if we can configure one UNIQUE Oracle Instance Client being shared by ALL the sap systems :
For Example
instantclient -> /oracle/client/11x_64/instantclient_11203
Is there a problem witch having one unique Oracle instant Client ?
Or should we we create dedicate Oracle instant client for each sap systems ? For example :
/oracle/JRP/client/11x_64
/oracle/BWP/client/11x_64
/oracle/SCP/client/11x_64
Thank you in advance for your attention
