Hi,
We are planning to build a Sybase IQ NLS landscape to support BW on HANA landscapes.
We have thought of installing DEV/QA NLS (IQ) on one server and accordingly have created the file systems on the Linux host. My question is whether we have to install sybase IQ 16 SP8 PL27 twice on the server to have two seperate $SYBASE install directories, from which we can source the environmenmt profiles while launching each of these databases.
The FS layout is as follows --- All FS's will be owned by sybase (2 sets of FS will be created with SIDs for DEV and QAS)
/usr/sap/SID/sybase ------------- sybase install dir
/usr/sap/SID/database -------- catalog DB
/usr/sap/SID/main -------------- IQ_SYSTEM_TEMP
/usr/sap/SID/log -- ---- Transaction logs and other system logs ----- Can the transaction log be stored here for Point in Time Recovery?
/usr/sap/SID/messages --------- messages
/usr/sap/SID/html ---------- html query plans
/usr/sap/SID/sapdata1 to /usr/sap/SID/sapdata4 --- for iq db spaces (user db spaces)
/usr/sap/SID/temp/temp1 to /usr/sap/SID/temp/temp4 --- for iqtmp spaces (both the sapdatax and tempx have same sizes)
Question ---- can the base directory /usr/sap/SID/temp become the IQTMP16 and will it access the other file systems (temp1, temp2 and so on) undreneath it or do we have to just create one file system - /usr/sap/SID/temp?
/usr/sap/SID/tmp ----- path for -dt option in the config file to store server dependant files. - I am not sure what this -dt stands for and how different is it from iqtmp FS (usr/sap/SID/temp....)
Question - In the First Guidance guide, this filesystem is mentioned as (IQ for Sort)... Does /usr/sap/SID/temp (iqtmp) and /usr/sap/SID/tmp (.tmp) have same sizes?
Question - Does the /usr/sap/SID/sapdata, /usr/sap/SID/temp and /usr/sap/SID/tmp have same sizes?
We will install DEV under /usr/sap/DEV/sybase and configure it to use the above file systems. Similarly, we will have filesystems for QAS but the install will begin from /usr/sap/QAS/sybase.....
Is it a viable way of installting multiple NLS databases on one server?
Please help....
