Hi All,

Have been installing ECC 6.0 SR3 on azure with linux and MAxDB. The installation at the phase 'Start Instance' failed to start. In dev_w0 and dev_disp found about some error as below.

ERROR => shmat(80248863,0x(nil),SHM_RND) (12: Cannot allocate memory) [shmux.c 1600].

Is it regarding a swap space memory or physical memory..have physical memory of 7GB and swap space 23GB. Attaching the dev_w0, dev_rd and dev_disp files. Could suggest idea/tip how to overcome this error.



dev-rd.txt (3.4 kB)
dev-disp.txt (53.1 kB)
dev-w0.txt (6.4 kB)

Is the MaxDB database running on the same host where the SAP instance is running? if yes then you will need more memory. First check memory assigned for database and for SAP. You should then consider increasing the memory on the machine.

Run sappfpar against the instance profile and fix any errors present in the output.

sappfpar check pf=/usr/sap/SD8/SYS/profile/SD8_DVEBMGS00_smartdocs

If the issue happens again then supply the contents of the instance profile - /usr/sap/SD8/SYS/profile/SD8_DVEBMGS00_smartdocs

You should also make sure that the SUSE Linux kernel parameters are set correctly for SAP systems.
