Installing the SASLINK AFL Plugins on the Appliance

The SASLINK Application Function Library (AFL) files are included with the server side components. These files must be copied to the SASLINK AFL plugins directory on the SAP HANA server.

Note: The SID referenced in these instructions is the SAP HANA system identifier (for example, HDB).

If it does not exist, create a plugins directory in the $DIR_SYSEXE directory.
1. Log on to the SAP HANA server as the root authority.
  
  You can use one of these commands.
  su - root sudo su -
2. Create the plugins directory.
  mkdir -p /usr/sap/SID/SYS/exe/hdb/plugins chown SIDadm:sapsys /usr/sap/SID/SYS/exe/hdb/plugins chmod 750 /usr/sap/SID/SYS/exe/hdb/plugins exit
Use this command to change the user to the database administrator.
```
su - SIDadm
```
Stop the SAP HANA database if it is running.
```
HDB stop
```

If it does not exist, create the SASLINK AFL plugins directory.

cdexe
cd -P ..
mkdir -p plugins/sas_afl_sdk_saslink_1.00.1.0.0_1
cdexe
mkdir -p plugins
cd -P plugins
ln -s ../../plugins/sas_afl_sdk_saslink_1.00.1.0.0_1 sas_afl_sdk_saslink

Copy the SASLINK AFL files from the /SASEPHome/SAS/SASTKInDatabaseServerForSAPHANA/9.4/sasexe and /SASEPHome/SAS/SASTKInDatabaseServerForSAPHANA/9.4/admin directories to the SASLINK AFL plugins directory.
```
cdexe
cd plugins/sas_afl_sdk_saslink
cp /SASEPHome/SAS/SASTKInDatabaseServerForSAPHANA/9.4/
   sasexe/libaflsaslink.so .
cp /SASEPHome/SAS/SASTKInDatabaseServerForSAPHANA/9.4/
   admin/saslink.lst .
cp /SASEPHome/SAS/SASTKInDatabaseServerForSAPHANA/9.4/
   admin/saslink_area.pkg .
cp /SASEPHome/SAS/SASTKInDatabaseServerForSAPHANA/9.4/
   admin/manifest .
```
Note: You can find the location of SASEPHome by using the following command:
```
ls -l /usr/local/bin
```
Restart the SAP HANA database.
```
HDB start
```
