Steps I went through, the PI server is dual-stack PI 7.31:
1) Check what JDBC drivers installed.
1a) Check path “\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\bin\ext\com.sap.aii.adapter.lib\lib”, found default “com.sap.aii.adapter.lib_api.jar” only.

2) Download JDBC drivers. I’m using sqlite JDBC driver, from https://bitbucket.org/xerial/sqlite-jdbc/downloads. The latest available driver i used is “sqlite-jdbc-3.8.5-pre1.jar”.

3) Prepare “com.sap.aii.adapter.lib.sda” to include new 3rd-party JDBC drivers. Refer sap note 1138877.
3a) Extract file “com.sap.aii.adapter.lib.sda” from installation source “\DATA_UNITS\JAVA_J2EE_OSINDEP_UT\SAPXI3RDPARTY01_0.SCA”. Refer sap note 1770206.
3b) Open zipped sda file, add downloaded sqlite jar file into “com.sap.aii.adapter.lib.sda\lib\”, then save sda file.
3c) Open and edit “com.sap.aii.adapter.lib.sda\server\provider.xml”, add new line “<jar-name>lib/sqlite-jdbc-3.8.5-pre1.jar</jar-name>” under tag <jars> , then save sda file.
3d) Place this prepared “com.sap.aii.adapter.lib.sda” file at “\usr\sap\trans\EPS\in”

4) RZ10, import profile, select profile “DEFAULT”, remove parameter “service/protectedwebmethods”, save and activate, then restart SAP services (or restart PI server also fine). Found out this step able to solve the 401 Unauthorized problem as mentioned in sap note 1600846, and due to reason from sap note 1439348.

5) Execute JSPM deploy.
5a) Open cmd at elevated mode, change directory to “\usr\sap\<SID>\DVEBMGS00\j2ee\JSPM”
5b) Execute: go.bat -config=”/jspm/forceMode=true” -config=”/jspm/deployVersionRule=updateAll”. Refer note 1123333.
5c) Select ‘HotFixes’ option as the package type, choose the detected sda file, proceed, then restart AS JAVA.

6) Done. Start playing around with PI JDBC adapters. 🙂
