Reduce the number of sapdata directories

Hello all,

I'm performing an ERP EHP8 installation for SAP NW 7.5 by using SWPM SP22 and XML Stack, also executed in Custom Mode in order to choose the parameters manually.

During the whole process there was not an option to choose how many sapdata directories should be created.

After first installation phase and Oracle Database installation (and patching) were completed I re-launched SWPM but I´m getting below error:

CREATE TABLESPACE PSAPSR3750 DATAFILE '/oracle/<SID>/sapdata2/sr3750_1/sr3750.data1' SIZE 16000M REUSE AUTOEXTEND ON NEXT 20M MAXSIZE 32700M LOGGING ONLINE PERMANENT EXTENT MANAGEMENT LOCAL AUTOALLOCATE SEGMENT SPACE MANAGEMENT AUTO

ERROR at line 1:

ORA-19502: write error on file "/oracle/<SID>/sapdata2/sr3750_1/sr3750.data1",

At first glance it seems to be an space issue but there are 279 GBs free in our /oracle/<SID>/sapdata1 file system, also noticed that the error points to sapdata2.

After verifying just realized that 3 sapdatas were created into sapdata1 (sapdata2, sapdata3, sapdata4)

Could you please advise if there is a way to reduce sapdatas and keep only one to perform the installation only there?

Also I would appreciate if you could provide a piece of advice regarding the error, probably would be necessary to keep 4 sapdatas and only correct the error

Thanks in advance

    Just one correction, the other sapdatas were created one level aboce sapdata1 and not into sapdata1, sorry.

    These lie into /oracle/<SID> path
