May 28, 2012 / RAC / By Brijesh / 1 COMMENTS At the time recovery in standby database if http://onlineappsdba.com/index.php/2012/05/28/asm-block-corruption-ora-01115/ you see error (Version 11.2.0.2) ORA-01115: IO error reading block from file 201 (block # 11080) ORA-01110: data file 263: ‘+DATADG/datafile/indx_8m.655.665578′ ORA-15055: unable to connect to ASM instance ORA-00020: maximum number of processes (100) exceeded ORA-01115: corruption in asm based datafile of 11g database on a standby database Steps to resolve issue: 1. Check ASM alert log file io error alert_+ASM1.log. 2. From ASM instance ================ sqlplus "/as sysasm" Increase the number of processes SQL> alter system set processes=200 scope=spfile; System altered. SQL> alter system set "_allow_cell_smart_scan_attr"=false scope=spfile; System altered. The parameter "_allow_cell_smart_scan_attr" is specific to exadata and in Normal systems with ASM will have this value as True which caused unwanted scans/processes to the ASM disks which caused io error reading ORA-20 and slight performance impact. By setting the value to FALSE in Non-Exadata will work around the issue. If OCR/Voting disk placed on shared Cluster file system, then bounce the ASM instance to reflect these changes,otherwise bounce the cluster in case OCR/voting disk placed on ASM file system.
