11gR2: Steps to Rename ASM Diskgroup with DB files
11gR2 introduced renamedg utility to rename diskgroups. I would discuss renaming a diskgroup on a Standalone Grid Infrastructure installation with Oracle Restart. Before you use the command, ensure that ASM diskgroup is dismounted. Below is syntax for the command. You can refer to 11gR2 docs for details renamedg [phase={ one|two |both } ] dgname=diskgroup newdgname=newdiskgroup [config=configfile] [ asm_diskstring=discoverystring, discoverystring ... ] [ clean={true|false} ] [ check={true|false} ] [ confirm={true|false}] [ verbose={ true|false} ] [ keep_voting_files={true|false}] Basically we have two phases of using renamedg command, phase … Read entire article »
11gR2 – SysAsm vs SysDba
SYSASM role was introduced in 11gR1 and was designed to administer ASM instances. In 11gR1 , if you connected with SYSDBA role , you used to get a warning which was only recorded in alert log (Refer to my earlier post here). But things have changed in 11gR2. While trying to dismount a Diskgroup, I found following errors SQL> alter diskgroup flash_arc mount; alter diskgroup flash_arc mount * ERROR at line 1: ORA-15032: not all alterations performed ORA-15260: permission denied on ASM disk group Above error indicates that I do not have permission on the ASM Diskgroup. As per 11gR2 documentation, SYSASM privilege is used for carrying out administration tasks on ASM Diskgroups. SYSDBA privilege can be used only for creating/deleting aliases and querying ASM dictionary views. Frankly speaking, you should unlearn the habit of connecting as “/ … Read entire article »
ORA-27146 Errors while starting up Database
Short post on a issue faced by me, while starting up a cloned database SQL> startup nomount ORA-24323: value not allowed ORA-27146: post/wait initialization failed This database environment was cloned and was being started for first time after cloning. Running hcve scripts on system indicated that OS kernel parameters were adequately sized. SHMMNI set to 1000 is adequate SHMSEG set to 120 is adequate SEMMNI set to 700 is adequate SEMMNS set to 2000 is adequate MAX_THREAD_PROC set to 256 is adequate NFLOCKS set to 1450 is adequate My Oracle Support articles suggested this issue is related to semaphores setting. As settings were correct, I attempted to start instance by commenting processes parameter in init.ora (setting was 1000). This time database started. I modified the processes parameter back to 1000 and attempted to restart the Database. It started again!! I am clueless … Read entire article »

This post is prompted by a recent issue where in DBA had modified racgvip script based on suggestion on one of blog (won’t name it).

Anyways I have put comment on the blog entry to correct or put a disclaimer … Read entire article »
