su - <sid>adm
cd /usr/sap/<SID>/ERS<INSTNR>
mkdir data log exe work profile
Starting with SAP kernel 7.0, the following subdirectory structure also needs to be created:
mkdir -p exe/servicehttp/sapmc
Replicated Enqueue Conversion: RE095
A couple of required SAP executables should be copied from the central executable directory
/sapmnt/<SID>/exe to the instance executable directory /usr/sap/<SID>/ERS<INSTNR>/exe
For SAP kernel 6.40 the list includes:
enqt, enrepserver, ensmon, libicudata.so.30, libicui18n.so.30, libicuuc.so.30,
libsapu16_mt.so, libsapu16.so, librfcum.so, sapcpe and sapstart.
For some releases, the shared library file extension .so is replaced by .sl. Apart from this, the procedure
remains the same. Copy these files and add a file named ers.lst in the instance executable directory.
Theers.lstshould include these lines
enqt
enrepserver
ensmon
libicudata.so.30
libicui18n.so.30
libicuuc.so.30
libsapu16_mt.so
libsapu16.so
librfcum.so
sapcpe
sapstart
ers.lst
For SAP kernel 7.00 or higher, the following executables need to be copied in addition:
sapstartsrv
sapcontrol
servicehttp/sapmc/sapmc.jar
servicehttp/sapmc/sapmc.html
servicehttp/sapmc/frog.jar
servicehttp/sapmc/soapclient.jar
For SAP kernel 7.00 or higher, the ers.lst file needs to have additional lines:
sapstartsrv
sapcontrol
servicehttp
The following script example cperinit.sh performs this step for 7.00 kernels.
for i in enqt enrepserver ensmon libicudata.so.30 libicui18n.so.30 libicuuc.so.30 libsapu16_mt.so libsapu16.so librfcum.so sapcpe
sapstart sapstartsrv sapcontrol
do
cp /sapmnt/$1/exe/$1 /usr/sap/$1/$2/exe
echo $i >> /usr/sap/$1/$2/exe/ers.lst
done
echo servicehttp >> /usr/sap/$1/$2/exe/ers.lst
echo ers.lst >> /usr/sap/$1/$2/exe/ers.lst
