Not able to initialize due to mysql error

[Former Member]

I am using MySQL database in hybris 6.6.0.3. I am getting an error when initializing or updating and cannot proceed further.Please look into the error CREATE INDEX IdxtargetPK_11005Sn ON asboostruletrig11005sn (targetPK); CREATE UNIQUE INDEX uidIdx_2242 ON asfacetconf (p_catalogversion, p_uid); CREATE INDEX searchconfigurationposPosIDX_2242 ON asfacetconf (p_searchconfigurationpos); CREATE INDEX IdxlanguagePK_2412Sn ON assigngractiong2412sn (languagePK); CREATE INDEX linksource_2412 ON assigngractiongrrel (SourcePK); CREATE INDEX idIDX_609 ON attr2valuerel (p_externalid); CREATE INDEX IdxsourcePK_6213Sn ON basestore2count6213sn (sourcePK); CREATE INDEX IdxtargetPK_6212Sn ON basestore2langu6212sn (targetPK); CREATE INDEX seqnr_2413 ON btgrefoptopages (SequenceNumber); CREATE INDEX btgRulResIDX_2406 ON btgresult (p_user, p_rule, p_resultscope, p_sessionid); CREATE INDEX ruleRelIDX_2406 ON btgresult (p_rule); CREATE INDEX IdxtargetPK_5310Sn ON campaign2source5310sn (targetPK); CREATE INDEX seqnr_5310 ON campaign2sourcerulerel (SequenceNumber); CREATE INDEX seqnr_1103 ON campaigns4restriction (SequenceNumber); CREATE INDEX compositeIDX_2_610 ON cat2attrrel (p_classificationclass, p_classificationattribute); CREATE INDEX IdxtargetPK_145Sn ON cat2medrel145sn (targetPK); CREATE INDEX linksource_2012 ON catalogs4basestores (SourcePK); CREATE INDEX seqnr_1080 ON categories4restriction (SequenceNumber); CREATE INDEX rseqnr_3003 ON catsforprodcarcomprels (RSequenceNumber); CREATE INDEX IdxlanguagePK_1089Sn ON cmslinksfornavn1089sn (languagePK); CREATE INDEX uncollectedorderscronjobRelIDX_1064 ON cmssite (p_uncollectedorderscronjob); CREATE INDEX IdxsourcePK_1713Sn ON cockpittemplcla1713sn (sourcePK); CREATE INDEX rseqnr_1713 ON cockpittemplclassifrels (RSequenceNumber); CREATE INDEX IdxlanguagePK_1148Sn ON commentassignre1148sn (languagePK)]; SQL state [HY000]; error code [7]; Error on rename of '.\hdcadb#sql-66880_63.frm' to '.\hdcadb\commentassignre1148sn.frm' (Errcode: 13 - Permission denied); nested exception is java.sql.BatchUpdateException: Error on rename of '.\hdcadb#sql-66880_63.frm' to '.\hdcadb\commentassignre1148sn.frm' (Errcode: 13 - Permission denied)]
