Oracle Database import question

[HK_10985243]

I am using Windchill PDMLink Release 11.1 and Datecode with CPS M020-CPS27

Can we import database using the following command: (This command has exclude=statistics)
impdp system/manager@wind directory=export dumpfile=EXPDP_acumedprd_19032023_01.dmp,EXPDP_acumedprd_19032023_02.dmp,EXPDP_acumedprd_19032023_03.dmp,EXPDP_acumedprd_19032023_04.dmp exclude=statistics LOGFILE=import_acumedprd.log schemas=acumedprd
And then run the following command as per article https://www.ptc.com/en/support/article/CS129969 to gather statistics manually:
execute dbms_stats.gather_schema_stats('DBUSER', DBMS_STATS.AUTO_SAMPLE_SIZE , CASCADE =>TRUE);

Here is what I do:

a. Export the current database with the expdp command and Windchill shutdown

expdp System/@wind schemas=PDM directory=expdp_full dumpfile=full_exp.dmp exclude=statistics logfile=full_expdp.log

b. Import the Oracle backup into the PDM user space

Impdp System/<password>@wind  schemas=PDM directory=expdp_full dumpfile=full_exp.dmp logfile=full_imp.txt

c. Gather DB Statistics

SQLplus PDM/<password>@wind

Execute dbms_stats.gather_schema_stats(‘PDM’,DBMS_STATS.AUTO_SAMPLE_SIZE, CASCADE =>TRUE

I do not see any reason your method should not work since in both cases the statistics are not part of the imported DB.
